Swap to a RB20DET
I was wondering if it was possible to do an engine swap from a KA to a RB20DET in mah '93 240. Is there ne modification dat would be needed to be done? thx for the help.

go to: www.unstable-hybrids.com
they did one. i don't really see the fuss in the RB20, since it doesn't really have as much backing as the SR, not in the states anyway.

Then why would someone get a RB20DET over a SR20DET? Can the RB20DET handle more boost than the SR20DET? If so, how do you know, and how much more on stock internals? I am really interested in finding out because I am considering both engines at this point.
Also, are there fitment issues with the RB20DET that you wouldn't have with the SR20DET? It seem like there would be. It would also seem like the weight balance of the car would be better with the SR engine. Is this true or no? How much does the RB weigh compared to the SR?
I know what SR20DET's sell for these days, but what about RB20DET's?
Sorry for all the questions, and thanks in advance for the help.

rb 20 clips go for 1000-1200 same as a ca.
i shall post my usual info about the weight diff hold up lets see here we go:
"that has absolutely nothing to do with anything what so ever.
Ever see the jms rb20s13? a typical rb not the 26 weighs about 50 lbs max over a ka. take the battery throw it in the trunk. remove the following: front bumper,ac dryer,ac condesor,charcoal can, old mechanical fan,ac lines,battery tray, window washer bottle,ac fan. and also if it's a s13 if you do a silvia convertion that will lose 27lbs also.
another thing if you use mounts IE -UH- or mckinney the motor will sit lower and back which also helps weight dist.
i hear this weight dist. bs agument all the time. and even from people who pull the whole interior and that can mess up front to back weight but it doesn't matter."
i quote this alot i see the argument everywhere.
also mounts from mckinney or -UH- help alot it makes it a drop in affair.

OK...I'm left to ask the same question I asked in the other thread:
Why would anyone get the SR20DET over the RB20DET? With the capability for more power, one would think it the superior engine. Do people get the SR20DET because it has more power initially?

wiring up a SR20 people say is hard enough, wouldnt an Rb engine be even more difficult to wire up?
Im going through the same debate right now, considering the SR or the RB, im constantly seeing threads with people having problems with their SR, maybe cause theyre trying to put out too much power with stock internals.
The thing i hate the most is hearing people putting in an SR and when they go to start it ..click.click..a big nothing.
I think its going to happen to me....NOooooooo.
what to do?
stick with KA and just add Turbo, cause my engine has 210km but i know it works fine. I put in an SR with 75km and ohhh **** it wont start.

OK...maybe I am confused as to why people pick SR's then...
Is the RB harder to wire than the SR? If it is, what sorts of wiring guides are available? The guy helping me with the swap is an electrical engineer, the other guy is a mechanical engineer, and I am mechanical as well, but I suck at wiring!
Are there still not fitment issues even with the UH mounts (turbo, hood, etc.)? How much do those cost incidentally? Even if they are somewhat expensive, you could easily pay for them in the money you save on the swap itself.
It seems like I am leaning more toward the RB20 now. As for the SR's being more "popular," that would be more reason for me not to get it.
