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?

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.

    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
