R34 Traction Control Mods

Hey guys,

I have a mate who has an r34 GTT 4 door auto with Traction Control. He has asked me to fit a highmount turbo and greddy plenum and fab his intercooler piping. He has already purchased a greddy plenum, but was told from a shop he was going to goto the you can't retain the traction control with a forward facing plenum. I had a quick look at his car today, and saw how big the throttle body / tc unit is, so I can understand why it won't fit, but I was thinking, maybe you could just cut the TC part of the throttle body out, and if I have to, weld a 2.5" hose tail to one side if there isnt enough room, and extend the wires, and fit the traction control butterfly in the inner guard or something?

If he can't keep the TC he doesn't want to fit the plenum, but I really want to put it on, as I hate the clutter of factory plenums. Has anyone ever toyed with this idea? Anything you can see going wrong with it?

Thanks

He won't do it if it gets rid of tc? Lol wut. Every person I know with r34 tc drives with it off. All the time.

Tell him to make his foot the traction control. Ie don't flat foot it in the wet and you won't need traction contol.

The reason that it would remove the tc is that the tc backs off the revs and won't let the car go. If you change the throttle body with a different one it won't work

Yeah I know exactly what your saying.. But he wants it, and it's not my car, so I cant tell him what to do. But not sure if you understand what I'm saying. The throttle body and TC unit is one piece, with two butterflies, and the TC has a control unit with motor... and I'm thinking of cutting it in half, so the TC unit is alone with its butterfly, control unit and motor, and plumb it into the cooler pipes in the inner guard, and just want to know if it will still effectively work.

Well tell him to go and pay someone else to do the work.

Obviously you are doing @ cheaper - gotta be harsh sometimes to people who don't think, you're doing him a favour as with a bigher turbo there is NO promise that TC will work correctly and not have an absolute fit 99% of the time as more power/less traction - and a bit of wheelspin will actually make it faster than TC totally shutting down the car

Your theory sounds good, put it into practice and let us know how you go :)

The OP suggestion will work in theory.

Also, I believe it was urtwhistle, modified his TC butterfly (shaved it down so that when it closed, it wouldn't fully close the opening) to allow a bit more power through when it kicked in, allows him to chirp 2nd pretty well now with TC enabled, instead of completely dying in the ass.

Bit of a thread mine, but thought I'd add to this rather than create a new thread.

When the traction control is engaged, does it do anything with the engine management (pull timing etc) or just close the butterfly?

Has anyone drilled some holes in the butterfly or modified it to make the effects less noticeable but still retain some traction? I like the idea of it, but the effects are a bit harsh

I wouldnt bother.

When i got my car imported two years ago, it was kicking sideways with traction control ON. Of course they took all the parts off it when they complied it -.- , but still, TC will be next to useless with anything close to 200 kw atw.

Really you guys are telling fibs

My car with 350 at the wheels still has TC.

I love having TC on when i dont want to die in the wet....

It works...not as well as stock...but it works.....

My car has plenty of power and the TC removed, no issues driving in the wet...

Yeh I have this handy thing attached to my leg, right at the bottom there. Useful little thing commonly referred to as a 'foot'. The right one is pretty effective for keeping me alive, when it's wet I simply choose to not be an idiot.

TC can suck it.

You might find that the engine will go into limp mode shutting down the injectors with the sensor missing. Just had this problem with mine. Had to use stager with deleted TC. Also you can remove the butterfly from the TC as I had done prior to fitting my greeddy manifold.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
