hey guys and girls... do u know if an rb30e sump will fit onto an rb20det out of a gts4? as im looking into putting one into my skyline, but want 2 remove the front defferential... also will an rb20det bolt straight up2 a rb30e gearbox? and last, but not least, will an rb30e crank angle sensor work on an rb20det, with the stock rb20det ecu and loom?

cheers, steve.

1 - Don't know 100% but I highly doubt it.

2 - Yes!

3 - Again, highly doubt it.

Do you already have the GTS4 motor or just have access to one? I will be selling my RB20DET long motor kinda soonish (none of the exhaust gear included, maybe the inlet manifolds but not sure yet) if you wanted to wait.

Cheers, Greg.

As Greg said. Not likely but possible, Yes, No.

yea i have access to a gts4 rb20det on the cheap, but in just trying 2 find out how much of my own stuff i can use, and what needs 2 be purchased...

RB30 sump wont fit.

Gearbox will but ratios aren't the best (depends what rear your running though)

CAS wont fit

Your better off spending a little more and buying a full long motor something like Dan has 4 sale out of his 31 at the moment

i think u might find it will fit because my rb25det has a rb30 sump on it

With an RB30 pick up?

no it still got the 25 pickup side by side theres no difrants bettwen the sumps

ok sweet, thanks for that.

GTS-4 RB20DET's use a differnt sump and a different block when compared to an RB20DET from a GTS-t.

I would assume the GTS-4 sump is the same bolt pattern as an RB26DETT, and im 99% sure the RB26DETT is NOT interchangable with the other RWD RB engines

just weld the holes up
