Ok i've just got a few questions.. What are the pros and cons of swapping any rb skyline series engine in a 240? I'm assuming its heavier and it costs alot more that a sr20 but it produces much more horsepower and torque.. So wouldnt the car be top-end heavy? Which would damper handling? So would an rb swap be better for like drag racing.. and the sr20 swap be better for twisties?

Also are the rb20det, rb25det, rb26dett all compatible for swaps in 240's?

Whats the difference between a red top and a black top sr20det?

Thanks in advance,
Mark

sear...well... u know by now

long story short: not being an *** or anything, but i've read at least two threads on each of ur questions here (most of them in the "Engine Swaps" forum). check it out, and then ask away if u can't come up w/the answers.

 

I did search and i didnt find the answers so.. Thats why i posted a thread.. I hate it when people say search and when you do theres nothing matching what you search for..

Search for RB20..RB25..RB26..SR20..READ..u will find ur answer. we have covered this so many times

 

funny, i found this in like 5 sec:

http://www.club240.com/forums/showth...AND+%2Arb25%2A

there was more, but i didn't feel like looking through all of it...

 

Ya i saw that thread about the only thing it answered was that rb20 and rb25 are compatible..And says what i pretty much stated above about the rb straight line ect.. But it also brings a new question to the table what chassis is a ca18 from i haven't ever heard of the engine before..

 

from old 180s..88-89 180s?

 

yep, and 89-90 silvias. also, if i remember right, one of the skylines (non GT-R, like R31 maybe?) came with it, too.

 

for the rest of ur inquiries:

blacktop/redtop:

http://www.srswap.com/

rb26dett:
- yes w/rb25 (rwd only) tranny (unless u wanna go for the first awd 240)
- yes w/single turbo, RHD conversion, or some kinda custom fabbed steering rack (apparently there are clearance issues w/twin turbos and the LHD position of the usdm steering rack

again, nothing that i've just put up here has not been posted a time or two before. although, i have to say that maybe the search function needs some tweaking. sometimes i can't find threads i know exist... hope that helps...

 

Really now? Thats interesting i have never heard that name before which is kinda weird.. But then again i never researched anything about those models.

I LOVE YOU. Thank you much for this info.

Mark

 

no prob!

 

Actually Mckinney motorsports has successfully completed a RB26DETT WITH twin turbos retained ina LHD car. If you had searched, you would know that...LOL
Anyway..it depends which RB series you are comparing. The RB and SR20 are so close in performance, it comes down to other things. The RB20 makes 215HP and 185TQ. The SR20 makes 250 on both I believe. So what you lose in HP you make up in TQ. Besides there are ways to remoe weight from the front to make up for the heavier engine. LIke i dont think the RB THAt much heavier than the KA. Remove the A/C and maybe move the battery to the back.

 

SR20 250 HP?? u mean 205 HP right..unless ur talkin bout the S15 SR..but whos got that installed

 

**** my bad...I never look back at what I type. I meant 205.
