While our household doesnt require any extra cars, I decided to give the FWD challenge a go, and picked this up just before I went to Targa Tas

2.2L MX6 Turbo for $500

Plans for now will hopefully be a bigger turbo and nitrous. .... if it doesnt blow up it may remain as a household hack and get an EMS ECU which Ed has laying about and some other stuff

Seen this car the other day, damn good buy regardless of the 13s for $1300 challenge.

Will be interesting to see what you cunts will be able to get out of it.

wow.
really clean for $500.

I had one of these in gold may years ago.
Full boost by like 2200rpm.. :lol:

was a good car.
I reckon this thing stripped will be great.

Gearboxes are soft from what I remember.

terribly, they shut down and 12 psi. i had a 13b turbo on my f2t and it would boost cut at 5 psi.
run ecu of some sort and remove the VAF

You'll definitely need bigger injectors too. VR4 injectors are apparently a drop in solution. Prepare for bulk torque steer.

Yep injectors are on the cards, and the thought of e85 too.

I have a feeling this may blow out the budget of the 13's build eventually ...

The stick turbo is tiny. They used to use Liberty RS internals to high flow the F2 turbos. I'd go with one of those T3 adaptors and a GT3071/76 sized unit if you can find one cheap. Or even a WRX or 200sx turbo should be the goods. You'll probably have to ditch the air con pump to get a decent dump pipe in there though.

Yep, aircon doesnt work so that will go. ... was looking at maybe a td04-05 as they can be cheap or t3 rb turbo of some description ... and some kind of extra injector or something as well as nitrous

I've got a S4(or maybe s5) turbo in the shed - there used to be an mx6 with one on it getting around.

Wes Mantooth
26-04-12, 09:32 PM
You'll find thr regardless of which turbo you use, it won't have a great deal more top end. The engines weren't built to rev and the standard cam is pretty shit after about 4000rpm.

I seem to recall something about 13Bt or 12At injectors possibly being easily adapted.

They supposedly did 15s standard.

The boost cut is a cunt of a thing. Prepare to headbutt the steering wheel when it cuts. Maybe find a cheapo interceptor unit thingy?

mate had a 626 turbo of the same model, was 100% standard other than a boost controller, on 10psi smashing boost cut with a dead clutch it went 15.9

getting around the boost cut willl be your biggest problem, but if you can then it shouldn't be too hard to do.

E-Z
27-04-12, 02:15 AM
Just stop the flapper from opening 100% that's what boost cut is, just the trap door in there opens too much. Stop it and then add more fuel with jerry rigging. I had a s4 turbo on mine first, bad combo, but for drags might be ok, it would only manage 2 psi in first then 6 in 2nd then boost cut at 8 in 3rd

TT
27-04-12, 07:51 AM
On that mx6 forum you will find what they call a VAF Hack.
There is probably instructions on how to do it.
That will take care of the boost cut in a dodgy way.

I recently sold a good condition rb20 turbo for $50 so you could get one of those on sau or boostcruising.
That was good for 160rwkw on the rb20 at 15psi.
Probably not for a long time though.. :lol:

Coffin
27-04-12, 10:19 AM
Ok so maybe an RB turbo might be better?

So can you just stop the VAF flap from opening 100%, say by obstructing it someway?

Motherfucker Jones
27-04-12, 10:25 AM
Put a screw through the body of vagina box so flap hits screw before flap open 100%. It would even be adjustable ;)

$100 just up the road turbo sounds good for 'drag car' and chemicals will help it spool :D

Spoonfed
27-04-12, 11:38 AM
I came here to offer advise based on experience, but all you smart cunts have it covered. lol. Stock turbo with a highflow will see 13's........... just maybe with enough boost and traction. I may even have a comp wheel somewhere still you can have (shaft snapped, wheel not too bad) if you can get someone to machine the housing out cheap? You have to also wack some springs on the waste gate to hold boost. They certainly don't rev and you'll be shifting at 4500rpm but hold boost/torque through the gears well so can surprise.
+1 on the cam timing idea, does help in the higher RPM a little, found this out by a flogged out crank key haha.

yeah i reckon if using gas go the rx7 turbo. big rear for max hp. mine used to rev out to 6k nicely

Coffin
27-04-12, 07:51 PM
Ok well some roadtesting started on this today, and there has been a few hiccups. First of which was the lack of brakes (but the last to fix .... they work fine now)

Biggest issue has been a fuel/ignition kind of cut that happens randomly and inconsistantly. New plugs, and fuel filter were done, throttle body cleaner all throughout the TB and it still did it. Put more new fresh fuel in it (had 1/8th tank of questionable fuel in it) .. still does it. .... Mr Jones thought it could have been the VAF flap opening too far, so we tapped a screw into it to prevent full movement of the flap and therefor "theoretically" preventing the boost cut .... still does it. (see dodgyness on the left of VAF below of screw insertion)

http://i66.photobucket.com/albums/h249/CoffinRX2/IMG_0281.jpg

Its also idling like a pig, so we drilled out the idle screw (see on right of VAF in pic) ... well moreso air-hacksawed it and adjusting it does nothing to the idle!

So any ideas?

Idles like a pig
Not over boosting (have "boost" gauge) plumbed in
VAF Flap not triggering boost cut (that we can tell)
Not consistant fuel/ignition cut ... but will generally happen off the line on light throttle, or after quick accel .... back off and feather the throttle .. 1-2 seconds its all ok again.

Motherfucker Jones
27-04-12, 08:21 PM
I'm thinking it's either fuel pump problem or that stupid vagina flap thing. Just remembered we have a fuel pressure gauge at work we could plumb in near the filter and 'mount' next to the boost gauge. Its bigger though so it may need to be zip tied to the wiper arm

Coffin
27-04-12, 08:30 PM
Guessing you not working tomorrow? :)

If its a pump problem, there is a Bosch 910 in the garage .. which I was going to eventually fit anyway ... if its a vagina problem, will have to source another cunt

Fuel pump. Had a Volvo 740 turbo that would do the same thing and it was the fuel pump cutting out every now and then.

Keep an eye on dodgy or busted vacumn hoses as well. E30's run a similar system and will run like pigs if any extra air is introduced into the engine without coming through the AFM.

Sounds like tank flush and pump has the issue sorted though.

boost-T went into it today, was donated by Terbulent for the cause.

Used to run about 7psi (on my uleh spec borrowed kPa gauge) .... now shoots up to 10.8psi (75kPa is the limit of this hectic instrument) by about 2500 and still keeps hauling, ... only problem the sludge in the fuel tank is back, ... going to see if I can get it in the hoist and remove the tank and flush it very soon. ... when its not surging its uber torque steer through 3rd gear

Nozzle location was fail. Everytime I hit the horn (dodgy nitrous activation system) it backfired. Moved it to the intake pipe and it was happy days… for a few hours. Apparently stock 4afe's don't like 100hp of gas for long…

I think the big problem with the box in these is the diff. It tends to fail and sends chunks of metal through the casing, destroying everything along the way. Might be worth welding up the centre as some insurance.

My old tx5 went 14.8@97mph with exhaust, intake 12psi and a remap. Really shit at putting down the power but I wasn't really buying good rubber.
Ended up getting a torsen lsd from guru which cost a shit load and didn't make much difference. When I got that changed there was already lots of damage to the side gears in the centre.
