LS/Vtec question
 

ok... well Im thinking of a b18a for my rex rather then a b16/b18c due to costs.

Now for the question. People say that a LS/vtec isn't a long term swap because the long stroke of the b18a will kill a high revving engine. Well, why not just swap in a b16 or a gs-r crank to shorten the stroke?

Re:LS/Vtec question
 

that is a mini me swap but you change out the pistons and rods as well.

Re:LS/Vtec question
 

thats not a mini me, a mini-me is a6 w/ y8orz6 head.

thats a b18a block w/ b16 head (ls/vtec)

but thanks, piston/rod/crank are different to the gsr (not including the intake manifold.)

Re:LS/Vtec question
 

how hte hell did i type mini-me??? i was tired as hell. so ignore it:)

haha!

back in NYc my friends use to call me the LS/VTEC king...
i would build them like once a week, for myself, my friends and customers. Every car i have ever owned in NYC, had a LS/VTEC engine in it last....what i mean is i would swap a GSR, later i would build a faster LS/VTEC and swap out the GSR.

LS/VTEC's are great.

Re:LS/Vtec question
 

the rod/stroke ratio is bullshit. it will last a long time. my 400sb is the longest stroked small block chevy and it revs to 7200 and will be for a long time... but its balanced :/

Re:LS/Vtec question
 

i have never blown an LS/VTEC, nor have i EVER seen one blew up, heard of many that blew up, but non of mines, nor the ones i built...(excluding the few i have seen on Boost blown)

Re:LS/Vtec question
 

LS/Vtecs are great!!! Sure the rod ratio isnt as good as the GSR or a B16, but I've seen some serious power out of them, and its about all I build for my customers too. Cheap way to build a GSR, and you end up with more torque, and with a little compression good hp #'s. One of my favorite little builds is ITR pistons. With a B16 head it gives you about 11.2:1.

Re:LS/Vtec question
 

well all this info has been very helpful.. I dont have much worries about reliability w/ a ls/vtec now...'


im thinking of a b18a in my rex over the winter. tare it down and rebuild it properly. and then in the spring slap a b16 head on it.

so I should replace the b18a pistons w/ ITR pistons?
