Hay fellas

I'm starting to build my r34 gtt and i want to get about 260 to 300 kw at the rears.

So far I have a blitz return flow fmic

A pod filter

A 3 inch dump pipe to cat, And 4 inch cat back.

Is the 4inch cat back exhaust to big ?

Or should I buy a turbo to suit ?

On the to buy list is

Turbo

Injectors

Fuel pump

And ecu and tune

Am I missing something ?

Cheers

also easy to get massive kw,

just buy the usual shopping list tonns of fuel lots of over priced parts with a massive turbo and you will smash massive hp

also have a shit as all hell car to drive which will last for 3 months.

hard to make big kw, usable, reliable and well tuned.

Aim for 260 rather than 300 unless you have to have 300. Then get a Hypergear bolton, unless you're rich. Nistune ECU if you want to keep it as close to standard looking legal as possible, otherwise just about any aftermarket ECU will do the job (Hypergear will want to sell you an Adaptronic, which is OK, others here will tell you to go PowerFC, or Link or it's cousin, all of which are OK).

If you retain Nistune or PowerFC you'll need a Z32 AFM. Get some fuel system upgrades and a tune and you'll be gold.

Oh, and a clutch. Oh, and some better brakes. Oh, and thnik about making sure the dampers aren't dead, and the bushes. And so on.

Yep.

Clutch

Brakes

Suspension

Diff

Wider wheels and good tyres

That is roughly 6k just there and without it you 260rwkw car will be slower than a car with those mods and only 200rwkw

At 200rwkw my injectors were maxed and clutch started to slip.... So yes you certainly need to upgrade all the supporting items....

and at 360rwkw your clutch decided it wanted to be permanent part of your fly wheel.

I've read this 3 times and I'm still trying to work out what you were trying to communicate...

Lol yes this is correct....

Shows when building a decent GTT that overkill is never enough :)

better than the flywheel wanting to make close friends with your ankle... seen that too.

easy to make power, hard to make a good car

Kind of irrelevant for OP.... GTT is a tough base and a damn good car when built right

I will aim for 260 but if I can get more I won't complain :)

So a 4 inch cat back exhaust is over kill ?

I run a 3" system and I'm making 363kw, that being said the exhaust is choking the car a tad I reckon BUT 4" is not necessary.... If you go 3.5" then make sure it has big free flowing mufflers and none of this hotdog and cannon crap :)

if you already have it, just leave it on. it's overkill, but doesn't mena you need to go buy something smaller.

Good pick up, I didn't see that.... Yeah keep it if it's quiet and street able

E85 also masks some of that too.

If you tried it on pump you'd be unlikely to get there :)

    • That looks good, but I think you're going to need much beefier side skirts now.
    • They are daft and there's a reason it never caught on. Steering feel? We don't need no stinking steering feel!
    • I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.
    • Define "starting to fail". Wy not just rebuild them?
    • Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
