    why would you "want" that? buy a l67. low compression is best.

    not really. generally you cant run as much timing, and that makes it slower. note my mod list, i needed meth to get to 17 wot timing.

    l67 and a 3.4 can run 18 all day long most of the time.

    That's because you're running meth and a 14.x 1/4 time. lol

    If you're really looking for performance, extra compression will be your enemy eventually due to detonation. Not to mention the weaker connecting rods on the L36. Go L67 and either mod away, or go turbo. If you really want the extra compression, go with L32 connecting rods and get different pistons.

    It depends how far you want to take it. If your just looking to have a fun mess around car that is safeish and has some power go with a l67. If you want to make a track car that's all out balls to the wall go with the l36 and higher compression.

    higher compression has more potential, but will only make more power in the absence of knock retard

    Look, I understand this is a very heated debate, but seriously man? If you're going to go drop insults for no reason, don't preface it with knowledge I'm pretty sure all of us know. We're all here to learn and we all make mistakes. And unless you have a degree in mechanical engineering, I'm pretty sure you're no better off than the rest of us. We appreciate your opinions without putting others down.

    There's for sure no 100% right answer on this because it depends on what your goals are.

    Thanks for the catch Scotty, I was intending to say the L67 rods over L36. I've had both side by side when rebuilding my engine, and the wrist pin area and stem were much thinner.

    In my opinion, if I was really going for performance, I would choose L67 and focus on boost mods.

    If you choose compression, you won't need as much boost per horsepower compared to the L67. However there will be a point when keeping knock under control will be a big problem.

    Personally, I'd like someone who's modded both of these platforms to chime in and shed some light onto what those barriers for each hp stage with knock for L36 and adding boost for L67.

    Again, my intention is just to provide my experiences and opinion, not to insult anyone or claim I know better.

    Good luck.

    there really is no rule of thumb here, its a game you need to play, and if you want a top swap buy a tuner first. your gonna need it.

    the game is boost vs timing, which one nets you more power via butt dyno. more boost less timing, or less boost more timing.

    stock pulley, ported heads, rockers, l36 bottom end i was able to run 14 wot, thats fuking it. and i was only making 6 psi. most top swaps will make 7 to 8. on a stock pulley. but the heads and rockers helped lower it some.

    got a fsic with a ported lim was able to get to a 3.2 with 8 psi, at once again 14. still weak on power, dont get me wrong, it was still better then a stock l67.

    added a meth kit, went right to a 2.8 pulley and 18 wot timing, (12 psi now) had some kr up top so i knocked it down one degree. and about kr free now, few blips here and there under a degree. i can live with that little bit.


    theres no way in hell you can pull off any of whats listed with out a tuner in your hands. unless you want to take shot in the dark with mail order tunes and updates. a top swap will need to be 100% tailored to your engine, no 2 are the same.

    in the end, the l67 will take timing and boost. why i wish i was able to source a l67, but a free engine of any type is golden. and funds were low, so thats why i got a l36 block. not my first choice really. it does run pretty damn good tho.

    If me and Scotty had an l67 right now we'd probably be able to run a 2.55 pulley which would be a completely maxed out m90 on a stock cam. So there's deffinately more power to be made with higher compression and really its not some super high compression build. Your going from a 8.5:1 to a 9.4:1

    Speaking of mistakes....

    I thought when you said "retard" you were trying to call one of us stupid!

    I was shocked that you would just drop that since every other interaction I've had with you was amicable.

    Wow. My apologies man! I cried I laughed so hard when I re-read this!
