All I can say is Ben, I didnt compromise, I got the 3037:p and all up fitted with HKS wastegate, manifold and all associated pipework, ceramic coating and braded lines it will be under 6k.

Rob, have you spoken to the guys at Per4manz Turbochargine - they were doing packages fully fitted for 5k about a year ago - pretty sure they were very capable of the sort of power you are after.

the gt30 seems very popular for the garret turbos. The gt35 is far to big for street. You can however get places like ray hall to change the front and rear wheels so your turbo does spool up sooner.

going for a custom job means that you get exactly what you want.

Going for a brand name you cant really go changing it as it isn't really worth it, as the cost u pay is a fare bit.

and remember you got for the garret turbo over the name brand you are getting it brand new, not second hand.

i'd also like to know what the gt30 goes like on a rb25

Has any one got any experience with these on the RB25 i.e where they make full boost etc?

The greenline kit is nearly 7k, the rx6 kit is a bit cheaper (by about 1k). I actually got the turbo from www.fvej.com, also got a hks wastegate for 290aud second hand in perfect conditon.

The rest is being custom made. I was supposed to be putting the car in last sat to get it all done this week, but the guy is sick so I'll have to wait.

Wouldnt be able to get a proper power figure up for a while anyways, as I have a head gasket and cams coming from japan, but they are on back order, plus I have to get my injectors and fuel pump fitted and a tune, so it will probably be a while yet:(

If you hunt around, you can get the bits cheaper than buying a kit - still waiting for a final figure (dont like setting price for custom work until its over - that way you dont get corners cut:) ) I have been given a rough price though - acutally be closer to 5 than 6 fitted - so you can save a quid.

With regards to fitting a GT30 500hp Unit on a RB Motor.

It normally comes off the shelf with a big comp cover and an externally ‘gated exhaust housing BUT….

I can do it with a .63 integral wastegate and a TO4B .60 comp cover that is a bit smaller. It will then all bolt on to your manifold and all is sweet.

Price is $2695.

If your interested I have been selling a lot of GT28’s with bigger (500hp) comp wheels fitted, these come integrally ‘gated and will be more responsive due to the smaller turbine wheel than the GT30. I have adapter kits to go from T25/28 to T3.. pic attached. Flange adapter kit is $150, GT28 500hp hybrid is $2295.

As I am chasing a turbo for my RB30 soon this is the reply I received from Tim @ Horsepowerinabox.

Joel, for a 3 litre, these turbos (from Per4manz in WA) have been used with huge success on 2jz motors, and very good on rb25 too. I would have got one if my 3037 didnt come up at the right price :) Basically a GT35 with GT30 turbine housing, externally gated

Most of the turbos we use come on boost @ 3-3500rpm for the serious hp applications or even sooner for street combinations.

 

Last 2 rb25's that I have done have made 320hp @ 1 bar (std engine) and 400hp @ 1.3bar (modified) at the wheels.

 

Can only supply propriety compressor maps and these don't have much detail (surge limits & max flow only) The gt35s flow @ around 80% efficiency @ 1 bar depending on a lot  of variables

 

Cost of one of these is $2477 inc gst

Edit: those adaptors look like turbulence city

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD?

      Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.

      So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!

      OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
