Rb20det

[cruzin33]

I just bought a freah import red top rb20det after killing my silvertop and i have two turbo's in my shed vg30 and sr1 rb25 both have minimal shaft play and are ready to bolt on, so what should i put on? The motor is pretty much stock apart from the hks pod, hybrid intercooler and 3inch zurst. The future mods will be remap ecu, hks head gasket,arp head bolts and a hks boost controler.

Any help to save me a day's work would be much appreciated

Cheers

RB25 FMFW.

The RB25 turbo runs the larger compressor.

The VG30 runs the rb20 compressor but with the larger r34 GTT turbine and usual r33/r34 rb25 compressor housing.

So.... If you can.. Drop the VG30 turbine housing on the RB25 turbo and you have the a R34 GTT turbo which makes the most power out of all.

yea what he said

did the same thing with my car when i suspeceted the turbo blew up, but found out later it wasnt the turbo, but if i was to do it again, and a little less cheaply! i would do the r33gtst turbo, as the vg30 is rather ;larger and laggy as a mofo! getting technical with the 30 housing on the 25 turbs is beyond be , but i would go the r33 gtst for sure if your chasing responsive, or big numbers go the vg30

i just put a vg30 on my r31... i recommend it completely sure the there's a tiny bit of lag(starts to boost at like 3500rpm)... but wen it does boost up its a hell of alot of fun... for normal drive and fuel economy lag is good...

i have the rb25 compressor housing and vg30 exhaust housing on mine, i reakon its laggy, but pulls hard on boost!

same here ^^ but with steel wheels.

i hate lag,

[Sambo33]

yep i have steel wheels too, makes you appreciate the stock turbo spool up hey?!

[craig R33]

definately

sounds like we have nearly the same gear

[Sambo33]

we do hey, we got similar power at the wheels too
