Hey guys only recently blew the standard turbo on my 34 gtt, i was going to just keep it off the road until its sent away for the build but i want to get it back on as i dont want all my rego going to waste plus its extremely sad seeing it sit there and not move...but anyway

Ive had no experience with upgrading into a smaller turbo class with the rb25s/neos etc...so was wondering if anyone could point me in the right direction as to what would be a good choice as a straight bolt on to the original manifold/dump etc i want something with a little more punch than the standard turbo as i want to run a bit more boost for the time being so any help as to what would be ideal to throw on and make a little more power and not have to go through a drastic tune or at least be relatively driveable once i bolt it on.

Thanks. B

Drop your blown into a turbo place like Hypergear and get them to highflow it. That will get you 240-250rwkw with supporting mods and will bolt straight up to everything and appear standard for the cops.

+1.

Either shoot Stao (Hypergear) a PM or give him a call and he can help you. Very helpful and the turbos are excellent from my experience :thumbsup:

Ill have to get on to them and perhaps post it or something cause im in the middle of rural NSW with no performance shops anywhere in sight so we all have to do everything ourselves around here..good way to learn but yeah do you know anything about what price it would be to get it cleaned up and high flowed? the car made 235rwkw at 10psi and i had it running at 1bar after a while, stupid idea and probably why it blew but I knew what i was in for and didnt mind as i was going for the new build soon anyway but that seems like a quick fix and being the same turbo would obviously bolt immediately back on thanks for the help guys

but you'll need ALL the supporting mods if you go the highflow route...

grab a std turbo and bolt it on, otherwise start planning to spend a heap of cash...

Its currently running a big trust front mount, power fc /w hand controller, avcr, apexi power intake, Z32 AFM, 3 1/2inch jasma exhaust, big sard fuel pump, hks plugs, hks SSQV3 bov and soon to have spit fire coilpacks so its plenty to handle the high flowed set up

If there are no shops to tune though, what you doing to do there?

You also need injectors

And for the record there is no way you made 230rwkw on the factory turbo, its impossible. At 10psi, 190rwkw would be about right.

What state? You will need a tune, nistune. There is a search box up the top right, select 'this forum' and punch nistune into that.

Drop an nismo, tomei, bosch fuel pump in the car and run 14PSI with a nistune and you will actually run 230kw.

Don't just get a high flow and run the standard ECU, no point.

Could have been flywheel kw...it has injectors already sorry didn't put that down and yeah I haven't even seen dyno sheets for it I'm just going off what the seller had actually told me so I'm not trying to spin shit, all I know is it ate my mates 06 sti, has beaten ve ss's, supras etc but yeah I'll have to dyno it after the turbo gets back..this is all a learning experience as I've never worked on these engines before

It sounds to me like the turbo you have blown is not standard. Never heard of anyone doing all those mods plus injectors and Z32 AFM for a standard turbo on 10psi??

Maybe it was a hiflow already? Post up some pics of it.

      Do you plan on using 98 or e85?

      This should be pretty easy. 200rwkW is just about the max power out of an RB25 stock turbo. So, 12ish psi on a 2.5L. That boost limited mainly by the prospect of seeing the turbine in the cat after the smoke show. A steel wheeled equivalent would likely happily do ~220rwkW at something like 17 psi, where it would probably be bumping into the usual limits of such a sized turbo. These things have like a .48 rear. You will not need the 0.86 rear. The 0.64 will be fine. In fact, if you were looking at various mid-200rwkW options for RBs, most of them would be in a 0.64 rear. So, I think you will definitely want to be no bigger than that for a same sized but probably even more efficient (at making power) modern engine.

      Well, it's taken me until the last week of 2024 to actually do something on the Skyline but I consider it a good head start to 2025's efforts! I managed to justify (to myself anyway...) my purchase of the lift table. It made taking the rear subframe out a lot easier than it would have been without anyway! Everything is out and stripped down ready for a clean then powdercoating.  She's pretty grubby under there but pretty good condition for a 38 year old Japanese tin bucket. 12 years of zero street time have obviously helped that... I need to decide which of the factory suspension arms I will keep and replace so I only get what I'm keeping powdercoated.  Baby steps but it's a start!
