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.

Thanks HOSTILE. PM sent.

writeoff i know a guy that isnt on these board is comming sunday with the HKS 2530's HKS cams cam gears and sard inj 800cc is making 330RWKW (should make more) he will be willing to talk to you and possibly take you for a ride but that sort of power is big money

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

yeah i heard you can get manual kits for arround the 300$ mark

manual kit? i got my shift kit (valve body upgrade - makes the shifts more instant but still an auto) for about $440 from mv automatics at blackwood. includes auto trans service.

yeah ^^ manual kit = manual valve body like u got i was speaking to 4door_sleeper he got his from there and i swear he said he paid 300 for the R33 auto box dunno if triptronic is much different prolly is

    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
    • I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
