ls/vtec
Whats up guys, my rings are on their way out so i'm thinkin about ripping the engine out and disassembling it. I've been reading about dropping either ITR pistons or B16 pistons instead of the stock ls ones. I just want some feedback on this before i start looking for parts. Let me hear some of your experiences and pros and cons to both. Is it cost efficient for the extra bit of power i'm gonna get from the compression jump?

Re: ls/vtec
I may be wrong but I think you have to use either b16a pistons, b16b(ctr), or itr pistons, not sure bout gsr's but im pretty sure you cant use the stock ls pistons with a vtec head like b16 etc...

Re: ls/vtec
the rods are a little too long (LS) to use with a b16 head. you'll have to change those out to use b16 pistons. Why not just go high compression LS? I did that and the engine had some pretty good pull. 84.5 mm pistons (GE), mild port and polish on the head, skunk2 valve train.
it was the very nice.

Re: ls/vtec
I think thats what i'm doin
I've got a lsvtec in it now. My rings are going bad so i want a cheap fix because i'm a broke ass. I figured up the compression while i've got everything apart. I've got a spare gsr crank too. would there be any benefit to pulling the ls crank out and running the gsr one? what would that do compression wise?

Re: ls/vtec
I'm not sure the GSR crank would change the compression at all. I believe the GSR crank was a little knife edged so it will cut down on the drag of the crank going through the oil of the oil pan. Please look into it actually fitting- the GSR was such a renegade motor that very little of it actually fit into anything else.
