thats not an ls vtec. LS Vtec is a ls block with ls rods and crank and a vtec head. not a ls with gsr crank and rods and a b20 head.

Like Dylan said, that isn't LSVtec. That's the head that someone got rid of so they could go B20Vtec.Im thinking about doing ls/vtec with my motor i just built. ive got gsr rods and crank with b16 pistons and a b20 head rightnow. i was just wondering if any has done this before.
Also, If you're putting the GSR rods and crank it an LS block, you're destroking the block. This is not conducive to making better power.
This is correct.thats not an ls vtec. LS Vtec is a ls block with ls rods and crank and a vtec head. not a ls with gsr crank and rods and a b20 head.

you could do a gsr motor with a ls crank and rods. Thats my idea of a true ls vtec.

i already have the motor built and in the car. i know its ls/vtec yet. i was going to get a b16 head to do vtec with. so what kind of power do you think it will make if i dont ask/

With what you have listed....140-145whp if you're using stock b16 cams. Give or take a few since you destroked the block by using a GSR crank and rods in an LS block.i already have the motor built and in the car. i know its ls/vtec yet. i was going to get a b16 head to do vtec with. so what kind of power do you think it will make if i dont ask/

Im confused here, what block do you have? Are you saying you have a GSR crank and rod setup in a LS block? Or do you have a non vtec head on a GSR block?

the head im going to get has gsr cams and im also getting a p28 that is chipped and has twostep. is a b20a a jdm motor? cuz i can get a complete motor that needs rebuilt for 50 bucks. and it sounds like that is the way to go.

The b20a is from the older Preludes and is the bastard child of B series. Stay away from it. It doesn't have the "bolt on" and "change over" properties with other b series motors that a b20b or b20z will have.the head im going to get has gsr cams and im also getting a p28 that is chipped and has twostep. is a b20a a jdm motor? cuz i can get a complete motor that needs rebuilt for 50 bucks. and it sounds like that is the way to go.

81mm b16 pistons in B20 (84mm) block wouldnt be good... why de stroke a LS.. the point of an LS is the rod x stroke ratio. Just cause you have gsr rods dosent mean there any better

b16Ls/v-tec is LS block with SI head or GSR head...

Technically it can be any B Series Vtec head... PR3 or P72
Instead of saying B16, ITR, B17, GSR, etc...
Why would you put a B20 head on there. It had it on already :what:
That wouldn't be an LS Vtec.
I got confused too.
