Last year I was given a Nubira with BHG, the owner considered it an economic write off and just wanted it gone. I drove it 20km home with 50% of the exhaust gasses exiting through the radiator overflow bottle and very frequent stops to refill the total loss cooling system. All of it's liquids and gasses were in the wrong places, I'm really suprised it made the trip. I've been tossing up weather to use it and promised myself I'd finish my Capella before I took on any other projects but it just looks too fun.

Basic stats as it stands from the power of google are 133hp @ 5400rpm, 184Nm @4400rpm, 1155kg empty, 0-100km/h 9.0 seconds, 5 speed 2.0L 16v.

It had sat for quite a while before the head we fixed the head gasket and it has some significant corrosion in one of the bores around where the top ring sits at TDC. It seems to idle smooth and goes alright though but haven't bothered to do a compression test, it is what it is. The cause of the faliure seems to be the pressurised plastic radiator overflow bottle had cracked. It's glued up at the moment but I plan to make a more permanent fix soon.

I live about 3 hours drive from my nearest drag strip so it's going have to haul me and mates under it's own steam (pun!) to any event and back again in relitave comfort (and legality!). Instead of going down the stripped out route, I'm thinking turbo plus decent management and go from there.

Budget so far:
2000 Daewoo Nubira CDX $0
New head gasket and timing set $260
Secondhand turbo, Mitsubishi Heavy Industriees TD05H-16G $120
Found cleaning the interior (-) $4
Gumtree Walbro fuel pump $70
New injectors $160 - http://siemensdeka.com/specsheets/FI114961.jpg
Secondhand "intercooler pipework" $5
Misc fittings for fuel system $5
Secondhand intercooler $20.55
Megasquirt MSII Extra inc. harness $535
Silicone bends and hose clamps $200
New standard replacement Excedy clutch with modified sprung ceramic button friction plate - $439

TOTAL $1,810.55
TIME -


Gave it a bit of a wash this arvo and will check out what it needs for rego during the week.

Youll probably find 100kg to rip out whilst keeping it legalish too.

I reckon 2.0l plus boost will do a 13 if it holds together

I started giving the interior a bit of a clean and to get the pub smell out of it, found a dollar! Also took it for a run on some private road and it felt retardedly fast compared to my Patrol. It made me realise I have not been in standard-commodore-fast car for a very long time. I think I'm going to have to do something about the yellow headlights under the safety spend. Rear wing has been removed for less shame and more speed.


I'm looking at my fuel system options.

Injectors
Siemens Deka 60lb/hr injectors I already have from years ago. Best price I can find is around the $40 mark, so $160 total. Will easily support more than the rest of the system regardless of configuration.

or

Buy a second fuel rail plus injectors from the wreckers and drill the inlet manifold for an additional 4 injectors. I'd hope that this would come in under $50.

or

Suggestions? BA Falcon injectors seem a bit too small at 29lb/hr. Any other OE options in 14mm worth considering that are 440cc+? PF members with anything for sale?


Fuel pump
I have a secondhand Fuelmiser universal inline pump, unknown capacity. I'm going to try and find a part number and specs. Will need to nominate a price if suitable.

or

A second Daewoo Nubira in-tank pump in parallel. EBay new is $49, might risk a wrecker pump if really cheap. As they are positive displacement type, I'll get roughly 2x the flowrate at the same pressure. Downside is that 2x might not be enough with aother bar of pressure. I suppose i could always have a cluster of 3 pumps in my tank...

or

Suggestions on a suitable/cheap OE pump or something for sale?

I have a spare 2jzgte rail with 440cc injectors, swimming type injectors, I reckon if the runner spacing was similar you might be able to cut to length and weld straight to the manifold

Couple of parts ordered. Secondhand intercooler $60 and 2.5bar MAP sensor $14.10 from RS, not paying $75+ for a GM 3bar MAP sensor. I haven't quite settled on engine management yet but what ever it ends up being it will need a greater range than the 1bar standard one.

I started working out where and how the turbo was going to fit. I looks like I can get away with a simple adaptor. Next step is a wood mock up. I'm going to retain A/C however it would be much eaiser with it gone.

http://i451.photobucket.com/albums/qq233/fsmx02/IMG_1319.jpg

Started on the fuel system. I'm going engine bay surge tank + pump + fliter in one self contained unit. It's a butane gas bottle purchased half full from a garage sale 10 years ago. If it's good enough for gas it's good enough for fuel...the top 90 degree bend came out of an efi Navara inlet manifold that I got from a church garage sale. Threads kinda mashed in, silver solder will fix it.

Roadworthy is happening independent of vehicle luckily, hopefully this week though.

I still haven't deceided on management. I see Greddy E-Manage Blue can intercept ignition trigger, I didn't realise it could do this, now it's back on the list again. E-Manage plus Jaycar DFA? Would probably come in under $200.

crack
03-06-12, 10:20 PM
this article (http://www.dezod.com/files/FICvsEMAN.pdf) should remove greddy e-manage from your potential interceptor list and add AEM FIC in its place.

i'd also check out the old haltech interceptor, which i have seen a few sell for at $350 (according to the previous article though, the AEM FIC is going to be hard to beat)

The plan for engine management has changed from the Jaycar DFA to a secondhand AEM F/IC purchased secondhand from a fellow pf member.

So the intercooler shown earlier in this thread was aborted with shipping issues on the seller's end so I came up with another one, $20.55 eBay purchase. 700x200x75mm, not sure what it's original application was.

First component of the water injection system also purchased, 100w inverter, $19 secondhand.

Cool, do you have a build thread or more details on your nubira?

RMX
15-06-12, 12:57 AM
No completed build thread, I started one on the daewootech forums but only made one post lol.

Basic rundown off the top of my head:

Started with the 1.6l (A16DM):
WRX TD-04L
PWR Cooler
Microtech LT10s
factory cast manifold with turbo flange welded on
exhaust
Leganza 2.2 Injectors
Turbo XS bov
China FPR
070

Broke the 1.6 and put in the 2.0 (X20SED) - I assume the same engine you have.
Installed a S15 T28bb as the TD-05 was a bit fucked.
440cc injectors and used the above gear on the 2.0l bar the manifold. A mate welded up a basic turbo manifold for me.

After a tune it made 232fwkw with the 2.0.

Factory gearbox didn't last long, Installed Holden/Opel Calibra F20 Gearbox with LSD - The dream was a 6 speed F28.

The car got rear ended by a Navara and was written off just as it was finished.

ls400x
15-06-12, 10:25 AM
Thanks for the details! Was 232kw on stock pistons and head gasket? I'll be very happy if I get anywhere near that much. Did you find the clutch and cv's held up ok?

RMX
15-06-12, 01:01 PM
Thicker head gasket to drop compression, stock rods and pistons.

Clutch was fine, CV's didn't like limiter launches .. same reason factory gearbox died. I was young and abused the shit out of it.

I also forgot to mention, To fit the turbo up and make oil changes possible without removing the turbo I used a Remote oil filter mount - the motor uses a Z154 filter, Same as 3.8l V6 Commodores so I used a remote filter kit to suit a Vn made by Speco Thomas IIRC.

ls400x
18-06-12, 12:55 PM
You're correct, my engine is a X20SED. I've read that a factory turbo gm variant comes with a MLS head gasket standard and the look to be pretty cheap. I'll try and save opening the engine again though and run the standard head gasket. Hopefully water injection will give me a bit of headroom.

That nubira in the video does 0-200km/h in like 11 sec!!

19-06-12, 03:50 AM
Yep, It was working pretty hard at 1.2 bar (And losing efficiency) .. but I didn't get to run it on another dyno or the strip it's possible that reading could be a little optimistic.

For daily duties it was running .8 bar and 194kw (on the same dyno lol).

It felt quick for what it was, I'd comfortably say it had above 210kw atw..

winging it or factory wiring diagrams at yo disposal?

ls400x
18-07-12, 10:54 PM
Winging it. The diagram I found was maybe 30% similar. The factory loom was coated in ectoplasm.

The AEM wants me to earth it's power ground to the factory ECM power ground and, signal ground to factory signal ground. Do you think it will cause problems if I just earth it all to one unknown ECM ground? I have no way of knowing what ground is what.

I'm not sure if I got the crank angle sensor connected correctly either. I can choose magnetic or hall type. I assumed it was magnetic but I dont know the polarity, AEM wanted a decision so I guessed. Stupid wiring.

crack
18-07-12, 11:23 PM
magnetic is usually two wire (polarity important), hall is usually three wire (power, ground & signal). i know that doesn't really help you much though.

it will pay to get the ECU power ground and signal grounds right. look for a common colour wire that comes out the back of TPS, MAP, ECT & IAT - that is most likely the sensor ground. remove the ECU plug and test for continuity between the wire common to those sensors and the same coloured wire at the ECU plug. hopefully that will work.

wiring is a bitch if you don't have good diagrams to go off (or if you haven't removed and stripped the loom).

ls400x
18-07-12, 11:32 PM
Thanks for the info. The CAS is 2 wire, the schematic has a picture of a coil. I found a Siemens part number but no specs.

That's a good idea for finding the signal earth, I'll try that.

If all goes to plan I'll put the exhaust back on and start it up to test tomorrow afternoon.

Given they're a delco ECU, possibly check some commodore diagrams?

ls400x
19-07-12, 12:10 PM
Iím more confident that the crank angle sensor is a reluctor type now, triggered by a 60-2 tooth wheel between main bearing 1 and big end bearing 1. At worst Iíll just have to change the polarity to the AEM (I hope). Somewhere between the injectors and the ECM the injector signal wires merge so the ECM only has to drive 2 outputs. Coils are dual post so itís just a 2 cylinder ECM. Makes for no cam angle sensor requirement.

It would have been so cool to get an accurate wiring diagram, second Nubira ECM, plugs to butcher so I could have made a patch loom in the comfort of my bedroom.

19-07-12, 01:07 PM
unless both injector drivers are driven low at the same time (i.e. batch injection) i would have thought a home signal was necessary. for example, if the ECU wants to fire 1&3 a the same time and 2&4 half engine cycle later (i.e. group batch injection) then it must know what half of the engine cycle the two groups of injectors are at and this can only happen with a home signal.

ls400x

It's just cylinders 1 + 4, and 2 + 3, 180 degrees apart batch I think, definately no cam sensor in the system.

19-07-12, 02:22 PM
yeah fair enough. wonder why they do it that way instead of full batch? (my mazda only has two injector drivers but it also has a home signal i'm assuming to ensure each group of injectors are fired at a particular part of the engine cycle.)

at the end of the day it makes fuck all difference to driveability, fuel economy, etc.

I gave up in the idea of an external fuel pump and bought an unused pump of boostcruising for $70 claimed to be a Walbro 225l/hr, it has no markings so I guess it's a lucky dip. Required a few mods to fit.

http://i451.photobucket.com/albums/qq233/fsmx02/IMG_1699.jpg

I'm not sure about how heat shrink will survive in fuel so I put a piece of fuel hose over the soldered join to insulate it just in case.

Daewoo has a plastic surge tank arangement spring loaded to keep the pick up on the bottom of the tank. The return line dumps into the top keeping it full.

http://i451.photobucket.com/albums/qq233/fsmx02/IMG_1701.jpg

Unfortunately the orignial pump has a unique fitting into the plastic housing that also seals into the steel pipe, would not work with the walbro so had to get creative. The steeel pipe also forms the pivot for the spring loaded mechanism so I had to retain it. I cut out a section so that I could attach flexible hose to the outlet and retain the factory lines and fittings external to the tank.

Work out where the wastegate mountings need to be on the housing then drill and tap into it (obviously separate it from the turbo first), or get bungs welded in, and tap those. Use washers if you need to to mount it evenly.

Without seeing the oil sender I have no ideas on it, sorry.

Made up an adaptor for the wastegate actuator. I still have to file the holes a little to get things lining up perfect where the 2 fasteners are missing in the photo. Unfortunately having a neatly mounted wastegate actuator means I had to remove the engine mount from the gearbox end (lower) block to the member under the radiator. I figure the engine mount will be easier to make work than the actuator.

Ah you've jogged my memory. This is an N13 18LE Family II block, Driver's side rear of the motor. The factory oil pressure switch has been T'd to use an aftermarket oil pressure gauge along with keeping the factory oil pressure light. There is a bung down leftward of this port which from memory was a 1/8 NPT fitting (check though as it was a while a ago that I did this.) With any luck you might also have the same oil gallery port there.

I'd like to change the end of the braided turbo oil feed to a banjo bolt though if possible, despite making a bracket to hold it out of the way it sits closer to the driveshaft than I'd like. I fear it one day getting loose and getting smashed by the shaft on a large bump and grenading the engine :(

Very interesting, everything looks familiar! My oil pressure sender screws in the oil filter housing in the lengthways direction, where the plug is in you first photo. I'm hoping mine has a tapped hole into the block in either location where your sender or oil feed is. That would make it easier for me not having to match the sender thread.

Maybe the hole into the oil filter housing is the same thread as the one into block on yours as a solution to your hose routing.

Thanks, I reckon seeing your photos has given me a direction to solve mine

I reckon there's a a good chance there will be a at least one tapped hole as that motor is essentially the same as what was used in the 2.0 Calibra turbos. There's a thread here that might be give you some more info:

Hopefully has a bit more in it once it has something resembling a tune, more than the 8psi that actuator seems to give, and a better exhaust. It's still got the original system including cat. The rear muffler is full of loose pieces judging by the sound it makes when I kick it. It's super quiet at the moment but good for listening for pinging.

AEM forums seems to have one other person with a similar problem, no real resolution. One thought was to change the region settings to US on my lappy. I did, no change.

How anyone can road tune a car by themselves without data logging I have no idea.

I'll check out Benaraby and Willow calenders, it seems to have no trouble cruising at highway speeds with decent reliability.

Had a breakthrough on the untunable areas after 5000rpm, turns out the standard exhaust system the problem. It would barely rev past 5000rpm let alone make power. AFR kept maxing out the meter rich for sensible inputs on my fuel map. I dropped the section between the dump pipe and the cat. Night and day difference, pulls to limiter easy now but I run out of time before dark for more tuning. I'm happy with my progress being the first ever crack at tuning/efi mods. Idle is still funky though.

I think I should fix up the air filter location and adaptor. Currently between it and the turbo is a 2" to 3" reducer with sharp 45 degree transition. The air filter half exposed to the back of the radiator fan to.

There is a 5mm step all the way around the transition from the exhaust manifold to the turbo adaptor and a similar step from adaptor to turbo. Goal for the first half of the week is to grind this out.

17-09-12, 09:50 AM
does your wideband controller come with a 5v output to power an aux device like a map sensor as well as logging capability? if so wire up a map on a couple meters cable, weld some bungs on compressor inlet, turbine outlet, post cat and post rear muffler. that way you can quantify and remove largest restrictions.

inlet sounds alright if it is 3" out of the airbox. what is the piping like pre airbox? could you add a larger pipe and make it a cold air induction? you've got the right idea with removing pressure loss.

Since my injector control seems to be all over the place I'm wondering if the fact that I've got 2 injectors in parallel is messing things up. The daewoo ECM only has 2 injector drivers and the wires split somewhere in the loom. Maybe I should try splitting the injector input into the F/IC and use 4 injector outputs. I also bought some ferrite beads to put on various wires to ward off noise voodoo.

I'm not too sure what the AEM injector druvera are happy with but I figure it's an easy experiment to test.

make sure all interceptor fuel and ignition modifications around idle are removed?

I have a short blanking loom that came with the AEM that removes it from the system. I'll give a go with stock injectors like you said. I think I can rule out the min throttle opening scenario as the hunting is perceptable all the way up to maybe 3000rpm under no load at a frequency of once per second ( AFR jumping between 14 to 20 ish still).

I'm down to a quarter of a tank of fuel and on my last road test there were some pretty big lean outs that were sometimes thrown into the mix. I'll top it up before before I add my fuel pump or fuel pump installation to the list of potential stuff ups.

I've got the standard MAP voltage clamped above 4.8v but I might reduce that to 4.5v as I seemed to have slightly less problems when it was previously at 4.5v. I haven't got the IAT in the inlet air stream because of the grommet fitting it uses and figured I'd tune around it. Maybe I should stop being lazy and think of a way to get it in there.

Must resist urge to look for cheap stand alone ecu's and blow the budget.

Deal haha. I fixed the wiring so that there is one injector per output on the AEM. It started and ran fine, 1050rpm and 10.5:1 afr and graduated to 850rpm and 14.5:1 afr after a couple minutes as you would expect. Then it started loping again. Noticable to at least 4000 rpm.

Pulled one injector plug off at a time. Lope remains.
Pulled o2 sensor plug. Lope remains.
Pulled coolant temp sensor plug. Lope remains.
Pulled TPS plug off. Lope remains.
Pulled IAC plug off. Lope remains.
Swapped polarity if crank angle input to AEM. Wouldn't start.
Re-checked all my connections, all good.
Put AEM MAP signal into the fuel reg signal instead if an individual barb off of the throttle body housing. Lope remains.

I did some more testing and I seem to have solve the hunting. I had the injector response time set to 690 micro seconds, I pushed this up to 1300 micro seconds and no more hysteresis. I can't get leaner than 10:1 afr at idle now as I assume this sets the min pulse width. Not to worry, that's probably par for the course for 61lb/hr injectors on 500cc cylinders at 800-850rpm anyway?

I then took it out for a few full load runs on the road. Afr is now consistant and steady!

The next job was to hook up the Autospeed spec boost controller I bought off of TT. Daewoo had thoughtfully provided studs to mount it to the firewall. At this stage I was pretty excited to get it back out on the road, as ususal, my do first, make informed decisions later methodology was employed. I backed the adjusters all the way out assuming this is min pressure relief valve setting and min regulator setting. I lazily brought it up to about 3000rpm in second and opened it up. It immediatly clocked the boost gauge well past it's last increment of 20psi and smacked the limiter. Hmm, pulled over and it had blown several small hoses off including one to the boost controller. Plan now is to read the instructions.

I got the driver installed for the USB to Serial adaptor so I can use the Innovate Motorsports Logworks 3.0 software however I plan to do all the logging with the AEM and the AEM logging software with the wideband as one of it's inputs. Watching the AFR trace in Logworks was intereresting as I could see the frequency of closed loop fuel trim cycles the Daewoo ECM was applying and under what conditions it would drop out of closed loop. Testing at no load, if I was too far off on my injector pulse width scaling resulting in a resonable devation from stoich the closed loop corrections would be too large each cycle. It looks like the Daewoo ECM would maybe drive from it's base pulse width to one that correlated with stoich at a frequency of about once per second. If it's base was too far from stoich it would overshoot or just the large afr change each cycle would result in poor running.

Nice one, glad to see this is still cooking after the hiatus. In my Family II N13 motor there's an N13 Exedy 5 puck disc with an SR20DE pressure plate, this has stood up to everything that's been thrown at it so far. Another advantage of this pressure plate is despite the increase in clamping load, the pedal effort feels the same. However I don't think the sam approach would work with this car, as the N13 Family II block has a different block casting to accommodate Nissan's engine mount locations and gearbox mount, which differs from the camira. However GM being GM, it wouldn't surprise me if a few tougher bits were available, perhaps from a twin cam Calibra?

Though that being said those things aren't exactly dotting every wrecking yard at the moment. Although there's another bloke here in the 13's challenge with a 20XE-Calibra-Powered Barina isn't there? He might have a spare clutch sitting around?
