What is the stock turbo size and max psis for the RB20DET motor? Motor construction? Intercooler size?

uuninja · 01-24-2002, 12:37 PM

Stock out put is 10 psi and the motor makes 215 HP with 195 TQ

All of the RB motors were aluminum block and heads IIRC.

IC is a small ish side mount like most other stock Nissan IC's  

The turbo looks like a t3 but the casting on the compressor housing doesn't say. I have read that it is a t3. The Turboon the rb20det is good up to 14.7 PSI from what I have read.

That should be a start.

Thanks a lot, Matt! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I always kind of thought the motor was Iron block, Aluminum head, but I guess not...

Intercooler is two-core, 24X12X6, if I recall correctly.

Ball-bearing Turbos available? $$$?

I also thought the RB was an iron block... the CA and FJ are both thought to be mini-skyline engines and they're also iron....

The RB is a made of Aluminum/Iron just like the KA. Its the SR that is all Aluminum.

I could be wrong. I will have to look it up.

BlankFlip · 01-25-2002, 02:21 PM

my rb was a stock ball bearing turbo, but i can't recall if all the rb20det's were set up like that.

uuninja · 01-25-2002, 02:54 PM

Yes the T3 on the RB20 is a BB from what I have read. It is also a common upgrade for CA and SR turbo's so in theory after market turbos for the SR and CA would also work for the RB20.

Hey, Halo, nice to see you man.

Matt, thanks for the info again. I was also wondering whether SR turbo upgrades would apply to the RB series. I'm seriously thinking of getting this motor for my next S13, but I don't want to get it without the US aftermarket support, and I'm just gathering information now.

Thanks, everyone, and thanks in advance for whatever I may get again. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

unless they're also swapping manifolds also......  I was under the assumption T3 and T25 flanges were different...
