Well it seems that at my last outing to winton raceway my turbos decided that enough was enough.

so im now looking to upgrade a bit. the thing that im having trouble deciding weather to stick with the twins setup or to go big single...

if its going to be twins, im looking at the garret 2860-7's.

i want something that going to give me good power/torque, without sacrificing response. the car does see a bit of track work...

but ive always liked the idea of the single turbo with the external gate screamer (love the noise!!!).

has anyone got any suggestions on what i can go for?

cheers.

matty.

You know what, i was gonna go for the HKS gt-ss kit but with all the trouble from EPA today its best to for for garrett stuff because if you do wind up in a testing booth, they will only see the garrett logo and think its stock.

everyone so far is saying the -7's are the bomb for track and street + add some cams for a little extra top end and your there.

I wanted a big single sooooo badly for the gate and look but honestly, after my recent exhaust EPA im sick to death of dealing with all the bullshit so stick to the lowmounts.

Ummm have you even looked @ GT-SS turbos?

They only have Garrett markings on them, Garrett housings etc.

Fact. Ive seen them, i have them.

Either way, GT-SS are not affordable anymore with the yen the way it is.

-7's all the way. You don't need cams.

so it looks like im on the money then. :(

its currently got the N1's on it, with 20 psi of boost the car made 310kw at the rears. what sort of power should i expect to se out of the 2860-7's with similar or less boost?

a bit of a curley one i know but im just after a ball park figure. im hoping for about 350kw (bearing in mind im getting larger injectors done at the same time.). do you think im dreaming, and what size injectors should i go for?

cheers.

near enough to the same really, GT-SS make around 330rwkw or so.

Depends on the dyno more than anything.

The -5's (next step up) will make 350, but they are good for a bit more, but then you hurt response so thats where the question lies

it seems the that -7's are the go,

would 700cc injectors sufice, or would i need bigger?

also is it worth spending the extra money on cams as well, or will the good ol' standards do the job?

700cc is fine, and standard cams will work a treat ;)

NA - Not Applicable! :bunny:

As for you conrad... i suggest rather than buying really expensive STI parts to make your car something its not, just get the genuine article. or at least get a real car... you can only abuse an "STI enhanced" badge so much! :bunny:

Shepo - I would have brought an STi, but the bank was being a complete tightass that day!! And "Expensive" parts?? That's what I have you for!!! Full retail is for chumps... And who needs an STi motor... I have my SHARPIE TUNE to take care of that department!!!

But then again. Whose car is running...? Hmmmm?

  • 3 weeks later...

Just thought i would update for those who may be interested.

im going ahead with the 2860-7 turbo's. also sard 800cc injectors (probrobly overkill, but better safe than sorry in my opinion.) and lastley getting a trust stainless steel intake piping kit.

once done, should be good for a bit more power. :P

will keep you all posted as things progress along. let me know your thoughts.

cheers,

matty.

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
