    i've got a stock b17a1, was wondering what a safe level of boost would be, hoping for around 260-280 hp, all new gaskets, new timing belt and all that....want to push around 7 lbs...possible or not...i've got a pretty decent budget, plan on building my head slightly, and of course fuel management

    you can boost 300-ish on stock sleeves, about 250 on stock pistsons/rods safely on most b-series motors in good shape and TUNED PROPERLY with an electronic fuel management unit like hondata/uberdata/etc

    however, you're never going to com close to 300 on 7 psi. lol

    i hit 290-ish on 11 psi on a sleeved 2.0 gsr motor with a t67 turbo.

    get some 94+ gsr cams. cheap, and effective for turbo motors. no other headwork is necessary.

    everything else, pretty much comes down to how much money you have to spend.

    ok, got a new idea...gonna hunt me an ls block, and put some better rods and pistons, and keep the block stock...would you still recommend that sc50 for about 260-280hp...and if im going to do this, i need a good piston, rod, crank, choice...or...should i buy a block that is already built? sorry for all the newbie gayness

    did you see the aftermath? my block was fubar. crank mains were out of spec almost .5". i had no oil pressure... but anyway, that motor is long gone...



    its pretty much a b16 with a little longer crank and different rod length. its no worse than a gsr or b16.



    ;)

    just wondering what kind of output i'd be looking at with about 7-10 lbs of boost on a built block w/ 10.0:1 compression...and was wondering whats prolly the most boost i would wanna push on that compression, while at the same time keeping it from being too incredibly hard to tune

    500 hp on stock sleeves = disaster, defenitly not reliable

    I would actually suggest a 60/48 turbo. Get a t3 42/48 and put a 60 compressor housing on it.

    260 hp is easily obtainable

    -t3 60/48
    -custom IC piping
    -JRC (yes a fucking JRC, 8" would be fine)
    -a full race manifold would be ideal but if you're on a budget any log should be fine
    -Uberdata
    -550s
    -Greddy BOV (most aftermarket are fine though)
    -3" Kteller Exhaust
    -Tial 38mm WG

    As for the b17 being the worst engine of the B's, maybe just the least reliable or not the best choice to start modifying. It's probably the best for a swap with IHE and that's it.

    Good luck finding rods for it, don't they have an odd size or was it just a stroked b16.

    don't sell the head... it actually has a pretty good flowing head.

    Texas; where else?


    if you hit only 290 on a sleeved 2.0gsr with a t67 pushin 11 psi, then, i would imagine that you were running lower compression pistons; but why sleeve it if you're gonna run lower compression pistons? were the pistons a lower cr? or, possibly whoever built your engine didn't do a very good job (and no offense if it was you). also, what elevation are you at?

    i refer you to hondata's dyno page: http://www.hondata.com/dynocharts.html

    i dunno, maybe these cars are special cases.

    also, you're always saying that head work "isn't necessary," but when you get right down to it, a good PnP is always gonna help you breathe better.

    and lastly, everybody always suggests full 3" exhaust, and at 250 or even 300hp, you don't need 3" exhaust. i'm sure a 2.75" or maybe even 2.5" exhaust at those power levels would have far greater exhaust velocity (in a mandrel bent system, of course. if you're using crush bending, then i suppose 3" would be needed.) if you're exhaust is too big, you will lose power, both in the bottom end and top end.

    finally, i don't mean to offend you by any of my comments, just my opinions based on my education thus far in my mechanical engineering degree, and from what i've read.
