fresh stock springs yes. If your springs are soft, then it would not be a good idea. All depends on the condition of your motor so i guess we’re both right
A non-built up ls/vtec can be had for about $1g, which would probably just be slapping the head on. It wouldnt be the “monster” ls/vtec everyone thinks aobut when you say ls/vtec, ,but it would still be ls/vtec.
Originally posted by notecLS Just by bolting on the head, only expect maybe 20, remember he wont be revving to 8000 rpm…
please tell me why only 20hp is gained from this swap?
(91 ls=130 and 94 gsr=170) since a ls/vtec displaces more than a gsr then shouldn’t the hp be at least equal! to be safe, the ls bottom end should be limited to 7000rpm but even at that rpm you’ve gained at least 30!

then you don’t know what you’re doing! i did an ls/vtec swap for $800. so it’s your pipe dream

Good luck on that motor lasting. And you redline at 7,000 rpm, that is such a waste. Most VTEC motors hit peak torque and horsepower well above 7,000 rpm.

gsr redline = 8000
ls redline = 7000
ls will make 1/8 less hp due to less revving
170 * 7/8 = 148.75
gsr has a better stock exhaust manifold, ,ls has like 30cc more displacement, those sort of balance themselves out.
And yes I know theres many variables i didnt throw in liek torque curve and stuff, but its still pretty close.

why wouldn’t the motor last if the redline is kept 7000k or under? wouldn’t it still be similiar to a stock ls as far reliability?
even if you don’t get the full benefit of the higher redline of a vtec motor it’s still better than spending 1g on an intake and exhaust(+5hp).
big difference! if you put a b16 head on a stock ls block you’ll get 9.5cr and 9.7cr with a gsr head. remove one layer of the stock head gasket and you’ve raised cr by .2
94-up gsr=10.0:1 cr
