Rb25 Turbos

[Bo0oSt]

hey guys any differance between the r33 series 1 & 2 turbos and the rb25 neo turbo ? just asking caus i was looking at boltin one onto my rb20...

r33 s1 has steel compressor wheel, and s2 has nylon

r34 has nylon compressor and bigger exhaust A/R (same size as VG30)

ok so what would yield better gains/effects on a rb20 ?

R33 s1 and s2 are really good on rb20s, just a tiny bit laggier than the stock turbo.

not too sure about the r34 turbo, not sure about wheel sizes compared to R33 but the rear housing is a bad match for rb20s.

I'd guess that the series2 would be better having quicker spool time? RB20 would take a little longer to spool a bigger turbo, so you might as well get the most efficient one you can.

i got the neo on mine, comes onto boost at about 2800, hits top boost at about 4200.. in 2nd, in 1st i spose it would be about 3000 and 4500.

Not much laggier than stock

hey ie got pretty much the same mods as you except the turbo and i was looking to get my ecu remapped as well. My power goal however was 200rwkw and ive been told that with the rb25 turbo zorst, pod, cooler and abotu 14 pounds, 200 was achievable so i was just wondering how come u have 170rwkw ?

DYNO A says he has 170rwkws

DYNO B says he has 200rwkws

DYNO C(and my favourite) says he has 500rwkws

And bragging rights goes to the bloke who uses DYNO C......

I could only crack a good 170-180rwkws on a rb25 with those mods except i had a powerfc. Need to remember every place you goto will yield a different power. Some accurate and some others not so accurate.

auto has different actuator to manual

[Bo0oSt]

well the advice i got was from re customs and ive heard good things about them...plus ive seen people on here in the rb20 upgrade section with that kind of power so basically the question still stands

2 rb's with the same mods are often far apart

no 2 engines are the same !
