The exhaust wheel in the lower turbo of my grey GTR shattered the other day and ended up as small particles in the cat. As such I'm up for new turbos.

I am considering R34 N1, HKS GTSS, Garrett GT2860-5 or HKS GT2530. I have sought advise from others on SAU here http://www.skylinesaustralia.com/forums/in...howtopic=131350

I am wondering if any GTR owners in SA have any of these turbos and could we meet up so I can jump in the passenger seat and experience their power delivery? I would also like to discuss other mods you've had to do to support the upgraded turbos and anything else related.

I'd be really appeciative and you'd heaping a fellow GTR owner. Thanks

PS - naturally I pay for fuel and a cleansing beer afterwards :P

I have an R34 spec motor in my 32 GTR which is running N1 turbos... currently making 251.4 kw atw on 13psi. No boost control yet but cant wait to dial up 20psi or so!! Clutch is struggling at the moment but can give you an idea.... I am in southern suburbs.

Hey talk to Bill from ATS. I think its gonna be expensive whichever way you go (new turbo x 2 = ouch) so I'd give him a call and he'll be able to give you very good advice on which way to go.

I have a S2 stagea (rb25det neo) and my turbo died so I went to ATS and they recommended either a GCG hiflow T28 (bill sends the turbo off to GCG and waits for it to come back - he gets the SAU discount price so its cheaper than GCG quoted price still) or the option I ended up going with which is Garrett GT30 (6 blade) internals machined up to the stock housing.

Obviously being all steel (and BB) I now have a bit more turbo lag than with the stock turbo but when it really hits boost (starts spinning up at ~2000rpm but reaches full boost around 3500rpm) it really goes hard all the way to redline!

Just another option worth considering. Comes with full 12month Garrett warranty and if you get Bill to install it he gives 6 months warranty on labour. He really looked after my car and did an awesome job. I'm not affiliated with ATS in any way - just a really happy customer. Its fairly expensive but well worth the money IMO.

He also mentioned the GT30 is good for ~300rwkw. and being all steel and a good ball bearing, it can a bit more boost :(

sounds good pixel8r so hows the stag launch now :D:P

I'm thinking of posting about this actually...

its not pretty at low revs (lag) but once the turbo kicks in (~3000-3500rpm) the front lifts up and it pulls nice n hard all the way to 6000rpm where it changes gears. Then lag comes back to bite again as it now drops off boost on the gear change (~2800-3000rpm) temporarily.

Obvioulsy I have a very mismatched setup at the moment so hopefully that will improve when i can afford to support the turbo with other mods...

Still, the recent sau cruise through the hills had the stagea sitting in the higher revs a lot so it went really well.

Unfortunately tho i was recently stood-up by my bro-in-law in a magna...gotta do something about that lag...

A side note - the stagea actually now averages 13L/100km city driving now, down from 14L/100km before...so thats nice.

wot u mean where it changes gears i thought u said sum where is a manual if so RB25det rev to 7g

even if u change @ 6000rpm you only gunna drop 1k in rpm u should still be on a good boost level

spewn about the magna do u want me to say ello to him :D:P

nah its an auto - tiptronic (r34 gearbox). it'll still rev to 7g (using tiptronic) but it hits the rev limiter too quick so lots easier to let it shift at 6g.

doesn't really "drop off" boost - just not on full boost from 1st into 2nd. and because of my restrictive exhaust it can take a little while to build up again - not too bad tho.

yeah i stuffed up the launch with the magna. was gonna stall it up but was too late and it really bogged down when i took off.

my car's not super quick but should've been quicker than a magna - still, thats how it is, its not about how quick your car is, its about how its driven...and in this case i lost. :D
