1jz is way better and cheaper than an sr20, y aren't more people doing it?Originally Posted by Echonova
i will say truely, finding forged internals or a greddy intake manifold for an sr20 is like finding parts in nopi for a civic. it is hard to get forged pistons for an rb20 and i don't know any company off the top of my head that makes an intake manifold for one. however most peeps on this forum wouldn't know how to drive anything over 350rwhp.
mike you remember that white s13 i was selling a little while ago, that clean ass one. week later the kid wrecks it....bone stock cleanest s13 i eva SEEN!!
a lot of the sr20's i've seen in the last 2 years were either stock, under 300 horse, or the person attempted 350hp and it didn't last 2 months before it dropped a valve, or the shim on the valve came out or it slung a rod through the block. i don't think i've ever met an rb20 guy that put a rod through the block. cracking pistons/rings yes, i've seen my share of both motors detonated, i personally i have done it to each LOL
that's y now after i see turbo dave i put tape over my boost controller knobs ROFL
i would like to emphasize the revability factor though. both motors aren't that huuuuge of displacement. so you pop a decent sized turbo on it, it's gonna be laggy, but once you can get into boost, you can twist the 20 up waaaaaaaay higher than the sr without valves/springs etc etc. true or false?
both motors got crappy turbos stock. however i'd take the sr's t25 over the ceramic crapola on an rb20 any day. sr20's t25 won't hold 14 lbs of boost all the way to redline....and the rb20's doesn't make anymore power after 5500 (stock or stock /w upped boost)
i believe 350hp is safer on an rb20 than an sr20. and more fun to drive since you can marinate in boost longer.
