hi matt,

i have a rb20 and i have been thinking of this for a while.. so do you only replace the compressor wheel. do you need the stock housing machined. lets say that i gor the rb25 comp wheel what power increase do you think and would this be the same power as if i were to just buy a full rb25 turbo.

thanks

If you bought the rb25 compressor you would have to machine your housing($50) The VG30 comp and housing would totally bolt on but make 10kw or so less. You will pick up between 20kw - 50kw depending on your tuning, mods and boost. I have made 225rwkw with the RB25 compressor. Depending on the A/R exhaust housing difference between your current turbo and an RB25 turbo you could estimate lag and power differences.

Any of these wheels will make give you a large power increase.

is the vg30 compressor & housing off the bb version or the plain bearing version? cause I'm pretty sure they have different shaft sizes....

if its off the bb version I would be very interested :-)

Yes they are different, this is a bb VG30. The RB25 compressor will make more power.
