How Do You Put An Rb20det In The 13's, Stock?

[PROJECTRB240SX]

I HAVE SEARCHED AND THE ONLY THING THAT I HAVE FOUND IS THAT SOMEONE HAS DONE IT. CAN SOMEONE TELL ME HOW THEY DID IT? I AM TRYING TO PROVE MY FRIEND WRONG. HE THINKS IT CAN'T BE DONE.

Traction and weight reduction are your friends...get those two things right and the rest will follow.

CAUSE IN A STOCK 240SX IT SHOULD RUN MID TO LOW 14'S RIGHT?

Find out wha an Sr20 does stock. I have heard most sr20 red tops do mid to high 13's stock I guess. They hav "about" the same numbers. Actually I believe the TQ is lower on the Rb20 than SR20.

the first rb swap -UH- did and i've seen the video to boot. was 14.1 @ 109mph. and that was with a open diff, the car spun the 1/8thmile and hauled *** the rest of the way.i would say if it had a good diff it would be 13.5. and that car was stock except for this. the uh plenum and a starion fmic and 1 BAR on stock turbo.and it had a N1 dual cat back. and my motor will be in after this weekend. and the goal is to have it ready for hyperfest in DC for the US drift nationals.

No way sr20 red top does mid 13's stock. Mine did low 14's with exhaust and boost.

I'm not sure comparing SR times with RB20 times is a good measuring tool.I'm pretty sure that the RB20 puts about 210-220 to the wheels, just like the RB25=240-250 rwhp and RB26=300 rwhpWhile the red top SR puts about 160-170 rwhp.

Therefore comparing them wouldn't be an accurate measurement for your times

Good point. I am skeptical on that though. i have read that, but have not seen ANY dynos to prove that. Maybe on the RB26 because of the gentlemans agreement, but the 20 and 25...I am skeptical.

[Imissmyturbo]

Ya the RWHP for the RB26 is right but I am guessing that the RB20 + 25 are lower. Just look at the Austrailan boards and see what they put down to the ground stock. The fastest I have seen an R33 with Intake, DP, upped Boost is 13.4. So I would think an RB25 in a 240 would run low 13's. I think we have about 3-400 lbs on the R33's.

I'm just going off of what Night told me.

Here's a good thread in SDU that shows a mildly modded r33 gts-t dyno figures. http://forums.skylinesdownunde...+dyno

250rwhp *stock* for a rb25 is a load of you know what. Whenever my s14 rb25 is done I will dyno it within a week for a baseline figure.

whats the conversion from KW to HP?

KW*1.341=hp

Imissmyturbo...are you talking about Rev210's car? He's done impressively well considering the very stock nature of his car...in fact, I'm going to try to follow his modifications a bit You notice he's still running the stock intercooler?
