Got an R 32 GTR, and I have noticed that the 33 GTR have much better suspension...

Is it possible to fit the upper arms from a 33 to my 32?

If so, will the geometry still be good?

Pics and/or drawings would be great!

Track only, don't have to be road legal...

you mean front upper arm right? because rear is the same design and therefore interchangeable for upper arms.

at the front the 33/34 design is heaps better - but personally if I was going to go to the trouble of custom mountings for the arms, I would probably just go to a blank sheet design anyway - a nicely space triangluar wishbone like the lower end has. I know of at least 2 cars that have put full custom suspension in the front, Mark Berry's 34 and Brad (Risking)'s 32.

Do they use completely different pick up points and re-designed subframe? I would love to do something like that, especially something to replace the super heavy upright (knuckle), I thought about getting them made (either cast or machined) from aluminium but either way would be expensive!

Yes, front.

If the inner fenders and whellwells are looking almost the same, I hoped for Bolt-on, or not too mutch velding...

But that is too mutch to dream about?

The car is race only, but class regulations states that it is supposed to be in street-legal shape. So custom is out. "bolt-on" is ok.

What class?

I race at "Gatebil" in Norway, and some other races that have national regulations in Norway.

cars competing are divided in classes depending on if they can be licensed for road or not, and I will race in the category "can" for as long as possible. (easier to win...)

i was Norwegian Champ in 2006 with a different car, trying to get the funds to win again in 2010!

nothing other than R32 arms will bolt straight in.

It would be possible to make the R33 uppers fit and use the R33 upright etc but I dont think it would be feasable.

The best way around it as duncan said is to use a completely custom upper control arm set-up that elliminates the massive upright and terrible upper arm. The other adavantage is you can fit some good sized wheels on the front. Up to 12 inches wide if you want to push the friendship a litte with the factory guards.

The front craddle is okay it just needs some mounting points welded on for the new lower control arm and away it goes.

There is no point doing all this work if your not going to buy software and redesign the front geometry, it can be so much better than it is but it does take alot of work.

Hence my move to a space frame car which has no limiting boundaries other than the ones I create.

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
