R32 Gtr Upgrades

[paulR32gtr]

Hey all,

I'm building a list of items to fit in one go to my R32 GTR.

List so far is:

- HKS GT-SS Turbo Kit

- Trust - Greddy - Extension Front Pipe

- APEXi - Power FC & Hand Controller

- HKS - Cam Pulley - Duralumin intake and exhaust

- Power Enterprise - Super Strong Timing Belt

Already on:

- APEXi AVC-R boost control

- APEXi super happy power intake

My queries:

1. Injectors / boost level - Not sure how much boost to run as yet I guess racepace will have a good recommendation - however - what are others running with these turbos and are the stock GTR injectors up to the task?

2. Exhaust - Does anyone have the trust front pipes and what did they use for the rest of the system? how is it?

I need:

a) a high flow cat and b) rest of exhaust that will bolt up - I don't want to muck around with getting flanges changed etc

I much prefer the thing being quiet as well - which does not seem to agree with the jap exhaust market

Recommendations peeps!!

any takers?

well to get the most of the set-up I would add:

fuel pump (nismo)

sard 700cc injectors

nismo or Z32 afms

basically any 32 GTR system will (should) bolt up to the Greddy front pipes. I would suggest an 80mm or bigger system would be the go.

This exact same question has been asked before do a search. Beer baron is spot on though you will want to replace the fuel pump and injectors before attempting to extract more power by way of upgraded turbos.

I have the same set up but with GT2530's insead of GT-SS's, and I have nismo AFM's. I didn't upgrade my fuel pump, or injectors. But I would recomend it. I have a 80mm cat back hooked up to my trust pipes, just boldted straight up. i'd recomend 80mm or bigger, as the trust pipe has a 80mm exit.

what did you do about the ..ahem.. catalyzer?

I'm a hippy that drives a gtr

[sav man]

my car might have come from japan with a punch through catalyzer. But i bought it off a car yard, so how am i to know

the trust kit bolts straight to the cat.

cool thanks for the info all

Pity I need to upgrade the fuel system but them's the breaks - want to do this properly and all at once. Gives me a good excuse to get rid of the leaky factory injectors anyhow.

So im adding

- Nismo fuel pump

- 2 x Nismo AFM's

- 700cc SARD injectors

- Trust PEII cat back and ill sort out a cat over here

Now I just gotta get it past management and i'm away - too easy

If Ben is doing the work i'd chat to him first about the exhaust

Also the other parts, depending on what you need, you dont "need" AFM's.

Ferni doesnt, he is another Racepace GT-SS setup with stock injectors/AFMs. There are a few small tricks, so have a chat first is my suggestion before purchasing.

[paulR32gtr]

Will do - gotta take it in for something else this week so was going to take the list in and pick his brain then.

Be careful of those Greddy dumps, they will need modification....the exhaust port is bit too big and the gasket won't fully seal on the flange.
