okay i found that the r31 version came with a stock 180hp versus the 215hp in the r32 version.

 

yea, redtop (r31) and silvertop (r32)


RB20DET red top
1986-1987: 178bhp (NICS version)
1988-1989: 190bhp (ECCS version)
RB20DET silver top
1989 onwards: 214bhp

Spend a few more and get silvertop if you decide to get one. Its a bit newer and has 35hp more give or take.

 

redtop rb20's suck, period.
dont buy it wiring is totaly different and its going to be old as crap.
no aftermarket support and you will be out whatever money you spent on it as no idiot would pay for any parts off of it.

The seller is just as stupid, who the hell does he think he's gonna sell it too?! Maybe parts for Japanese only! I love how Carl is so brutally honest, its nice to have around hahaha

Well said Carl

 

They came in fairlady z 200zr's too. I suppose if some one wanted to restore or "make" a z31 200zr, they would want to buy that motor. As far as 240 swaps are concerned, they are completely worthless. r32 - r34 motors were built relatively the same and all have good tuning potential. I'm sure the redtop could probably make 250-300 whp, but it would not be worth it compared to an r32.
