Ive been on Zilvia.net for awhile now. I have a S13 that I have stripped down to just a shell pretty much, no motor, no trans, no harness, etc. I was planning on doing a KA-T in the beginning but now I am almost certain that I want to do a RB20 swap. I have looked through countless threads and post about the swap. Now I would just like to see if anyone on here has done the swap and if so are you satisfied with it? is there anything that you regret now that you could have done different?

I have a 25 and regret not just getting a 26. The RB20 and the SR20 have the same displacement. The RB has the skyline factor but the SR is a direct swap and will be way cheaper for name brand parts.

If you go RB I'd recommend the 25 or 26. If you want RB20 go SR20.

RB20 is pointless

even a 26 is semi pointless. when there are options like 2jz for cheaper, the only reason to do RB-ANYTHING is to be able to say you have an RB.

if you dont care about the letter R and B together associated with your vehicle... your inline 6-cylinder swap should be a 2jz.

I don't see anything about "people who don't have RB's" or "give me toyota motor opinions"Prepare to be flamed by RB owners everywhere, forever...

people who hate on rbs prob have never done one, or they had one and it was a lemon and blew up on them or something. i have a s13 with rb20 and im very happy with it. sure most of that is due to the fact that i got it for a steal. so i would say if you can get it cheap (around 1k for whole swap) DEF do it. its a fun a** motor, takes a beating and can make decent power with a simple turbo upgrade. do i wish i went 25? yes but at the same time theres always tomorrow. the way i feel owning a 20 right now and then moving up to a 25 or 26 later on just gives me valuable experience in working on the motors learning them and whatnot.. plus like i said i got mine cheap so if it f***s up... oh well. IMHO if you can get a rb20 for cheap go for it, they are cheaper than sr20s at the moment so i don;t see why not.

with my rb20 s13 hatch on 10 psi vs my friends built sr20 running low boost 8 psi in a s13 coupe we were dead even. my car is way heavier and his is just being broken in from a fresh build till he gets it tuned. on the dyno i made 219whp and 184 lb/tq. go for it man you'll love it.

he's pretty much right. I sitll love sr20's they're simply more practical.

buy / build whatever motor you know the best.

1jz's and 2jz's require extra work w/ fuel lines... and brake booster + cylinder.

BUt if you like rb's get one... if you like 2j's get one of those... if you like ls motors get those.

cost benefit analysis leads to twin turbo LQ motor with holset turbos... massive power... and very driveable... not too expensive either. thats my vote from personal experience.
