Hey guys i just brought my first r32 gts-t i was wondering which turbo would be my best choice. it already has a gt35r on it an its a laggy as f*k it starts to make boost around 4300 an full boost around 4600.car has wolf3d, larger unkown injectors sard fuel reg.custom turbo manifold with external gate etc etc.After around 200-230kw.what would be an ideal turbo that makes boost around 3000? any thoughts would be greatly appreciated.

Have you driven a car with that much? That turbo is rated for 300+ kws or so... that's a big drop down!

I have a VG30 turbo lieing around (slightly better then an RB25 turbo)... you could highflow it for around 220 - 230kws...

NYTSKY mate i was thinking along the lines of a gt30 when do they start to make boost?a lot of people on here seem to be using hks GT 2530. Mlr mate with the cam gears what sort of rpm do u think this would lower the boost range by? thanks

Not sure mate, I'm looking into this as I'm having the same thing going on with mine, rb25 with gt35, tuner recons it will drop between 250 to 500 rpm.

Not doing this though till next year when its going in for a rebuild so no answer on this for a while from me, sorry.

I'm sure someone on here could give you a definitive answer.

Yeah i will do some searches on that an thanks man.

Unbiased opinion.

GT3076R would be good choice

But if it was me I could not go past the Billet S56-GT3 with .63 A/R hot side.

The S56-GT3 specs are pretty dam good

The S56 compressor wheel has a 56mm inducer and 80mm Major + (ETT).

Turbine has an exducer of 56.6mm and a major of 65mm and is made of 713C Inconel

    • Actually, if having and keeping the stock ECU is the plan, the correct answer is to put Nistune into the ECU and improve the situation, not just look at it.

    • Yeah so physically that port is consult not OBD2, but also be aware that "JODB" is not really a thing - it came in around 2000(ish) but is not a standard like ODB is, each manufacturer had differences. If you are looking at ECU only and have a standard ECU, go with Datascan as Turbo Tapin said. Per another recent discussion here thought that won't do other systems like in a modern car, for example bleeding ABS
    • They're not rebuilt Racepace items. They were mint. From memory the were ex display stock that I bought off yahoo and he ran....from memory he barely used the REs when he replaced them with a set of Tein RS If have been stored correctly and not leaked fluid then they will be mint   As an observation the Racebuilt rebuilt Tein RA/RE/RS were a better street/club/track package. Really nice on the street and did good numbers at the track.  I think the factory Teins wont match the Racepace valving on the street but would be in the same window of performance on the track... albeit firmer
