iv got some quotes for my r33 gtst s2.

the aim of the car is a high 11sec on street legal tyres.

i got 3 quotes of 3 different places all the quote were similar but all used different turbos. which are.

t61 bb inovative turbo 650hp

t4 garrett 650hp (bush baring)

gt30 bb 600hp

what are your thoughts on these turbos

1 guy said to use the standard manifold and modify it

what are your thoughts on the std. manifold

on high boost it willbe making around 270-290kw on about 20 pounds

also what are your thoughts on ecus. caus all used diff. ecus

microtech ltx12

autronic

apexi p. fc

any help would be good

thanks

on my 96 s2 GTST:

im running a LTX12 ecu (the lastest one not the first LTX12)

T04 on custom manifold

im told for 300rwkws with this setup i will only need bout 20 psi which isnt much boost

my car hasnt been started yet or dyno'd but with this setup, my new cams and the rb30 im hoping to make bout 350rwkws or somewhere it that region

should produce a high 11sec 1/4 pass on 300rwkws or so

the reason i went this turbo as it only cost me $900 brand new and costs $300 to replace the bearings if they ever fcuk up :D

but the other 2 turbos would suit fine, but cost more and are more expensive to fix ($1000)

just my 2c

      R32 update from 1990's spec.

      So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House

      RB26DETT Sketchy boost mod?

      Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?
