    Work is progressing. Lots of parts coming out of the 180. Dirty parts. The last time I drove the 180 was at Wakefield 2 years ago, and it was really wet. I made several shortcuts through the sandtraps that day. Seems as though I brought a bunch of Wakefield home with me. Every move I made under the car when removing the driveline goodies resulted in eyeballs full of car crumbs.

    Diff, clutch and dirty gearbox.



    Dirty brakes and shiny rocker stoppers.




    After all that dirt I thought I'd give the Silvia it's first wash after being detailed last month.




    Been ordering and waiting for random parts to come in the mail. Cams have been quite a saga, so far they've done 2 trips from Sydney to Toowoomba.... hopefully they'll back in Sydney this week. Lightened flywheel came from Melbourne. Oh, and so did these:



    I've waited a long long time to be a trumpet owner. Pretty stoked, can't wait to play some sweet tunes on them.
    Thought we should at least get some mesh filters. Ugly as fuck. I prefer open trumpets. But we can't have rocks getting in and jamming the throttle open or something silly.




    Once the parts pile gets a bit bigger we'll the Silvia in the garage, yank the engine and start fitting all the goodies.

    I suggest if you're going to be running any sort of angry SR20, that you get a set of these for the gearbox: https://www.rhdjapan.com/kameari-sup...a-skyline.html

    The absolute cheapest mod for NA's is to run the 6 speed box with a 4.3 diff.

    Normally 6 speed is run with 3.692 final drive. I crunched the numbers once, running with a 4.083 ratio, its equivalent to a 5 speed gearbox with 4.9 diff, BUT, still has a highway friendly top gear.

    6 speed + 4.3 is just that little bit more special. DumHed's budget car (with previously mentioned budget 120kw NA special) was doing 1.08's at Wakefield with that setup.

    Pics of the car look great man. I wish my rear guards weren't so mangled...

    That gearset looks tastey. Wouldn't mind a 6 speed too, something to look at in the future. Right now we'll have to stick with the 5 speed and the 4.3 diff due to budget. The diff needs some dhim removal, at the moment it has 1.2 and 1.0mm shims in it and is effectively locked. Not so nice on the street. Has to be a compromise there.

    Thanks. It's not quite so nice up close. Some cock has keyed it at some point, the front bar needs paint and there's some nastiness around the sunroof. It's a 5 metre car now, before it was about 20.

    those mesh covers for the trumpets are shit iirc
    better off with actual filters that allow some some space from the trumpet itself from memory?

    Yep, even socks outflow them.

    This will be a lot of fun.

    Ah fuck, seriously? I thought socks were the worst, thats why I got mesh!
    I'd prefer to have nothing and just suck birds and grit into them, but I worry about that odd stray rock jamming shit wide open.

    Latest theory I read on them is that you're better off with an airbox hanging off the trumpets with a filter on the end of that, as per bike engines. Supposedly better throttle response.

    Hmm. I think this is going to be one of those situations where asthetics are going to win out over functionality.
    I'll just have to drive it harder.

    Yep, despite how many people do bare trumpets with ITB, plenum > no plenum

    Thinking of using the electric vacuum pump off a Holden SIDI V6 to supply the brake booster now that there is no longer a port on the manifold. Anyone got a problem with that?

    Yeah do sidi booster & post up pics so I can copy you in few years haha
    an easy fix is get a mate to drive in front of you at 60 then 80 then 100 and mark in on your speedo with some liquid paper.

    I've daylied and raced my s13 with a chasebays booster delete bracket for about 7 years and never once had an issue. It makes for a much cleaner engine bay.

    I can get the SIDI pump for $0, and it's easier to wire that up than remove the booster, and I get to keep boosted brakes.

    Pump seem unnecessary. You are going to need a 4 into 1 little chamber for the map sensor anyway why not run the booster of that?

    Yeah I got that with the throttle setup. Bu the outlet is tiny. I'm worried about even teeing the fuel pressure reg vac hose off it.

    oh well if its free that's a different story. I assumed you would run an alpha-n tune.

    A what now?


    Just ordered a fuck-tonne of seals, gaskets and a timing chain kit from Taarks. Cams should be back from their Queensland holiday in a day or too. Had to send one of the trumpets back for exchange, the bellmouth was a fraction too big and the mesh filters wouldn't fit on it. Joys of building cars, waiting on parts.

    Alpha n tuning is commonly used on itbs which uses tps vs rpm tables instead of map vs rpm. Often using itbs there isn't a stable enough map signal at lower rpm so you can get better drivability using alpha n. It really depends on the size of the cams you plan to use and the signal the map sensor sees. You should be fine with the map sensor but if it drives like crap you may have to look into ditching the vacuum chamber and going alpha n.

    Actually most ecus now days can do a combination of the two types so alpha n will be used in lower rpms where the map signal is poor then it will swap to speed density higher up.

    Ah yes, thankyou. Hopefully whomever tunes the Haltech will be able to sort that. It has a built in MAP sensor so it would be silly not to use it.

    done this on track 911 and 240z works well. blocked off the fitting on the manifold.
    also i use ITG filters (use their sock filters if you have to)


    i know you said no plenums but a carbon one is really effective/porn/great noise

    Well it's good to hear somebody else has used that pump. Just ignition power through a relay?

    I know an airbox is the smarter, performance minded way to go about it. I'm not going to lie though, 99% of the reason why I wanted itbs was the glorious induction noise and the look of the trumpets. Performance wasn't really a factor. I'm expecting less power and poor driveability compared to a single throttle standard manifold. Worth it.

    I'm spewing that the throttle cable will have to run across the top of the rocker cover due to the way the throttle cam is oriented. It will look horrible. Priorities.

    not 100% it's that specific pump but i do know it's off a holden commodore so surely same-same. can't fault it, 911 originally couldn't get enough vacuum from ITB's so the brakes were shithouse. rather than source a non-boosted pedal box and setup ($$$ because IROC guys use them) just added the pump. worked well so did it to the 240z later. should be fine for this project!
    you won't lose induction with proper air filters, the ITG ones leave heaps of space internally for air flow. the mesh is just shit.

    Awesome, thanks! Will surely be an SIDI pump, they're the only ones that run them.

    Whats your opinion on hydro handbrakes for rookies drifting?

    Necessary? Easier? Not needed at all?

    Depends on the car. In my VL i fitted one because the standard handbrake is junk. Worked fantastic.
    Standard S chassis Nissan handbrake works really well with the handbrake built into the calipers. I fitted GKtech lever extenders to the calipers to make them that little bit more awesome.

    Guys running Skyline rear brakes tended to have dramas with an innefective handbrake because they have drums with shoes.

    I really recommend a good handbrake for beginners. I didn't have a working one until 2 years into it. I had to learn the hard way.
    Don't use it too much though, flat spots delaminate the tyres real quick.
