My buddy is building a ls/vtec and i always heard you had to change out the pistons to vtec pistons is this true? Cause hes saying he wants to use the stock ls pistons and i dont want him to mess it up. Please help..

 

No, I think you can keep the stock pistons. Now is a good time to change them if he ever want to upgrade though.

 

, but you'll get low compression.....and you can't rev high at all or else your valves will hit the pistons.

 

you can keep your stock pistons....ls/vtec is a headache.....right way--->if you go this route,then do it right by putting all the oil sprayers,oil pump,tranny,etc...etc.....be prepaired for motor oil leakage......thats normal on ls/vtec....unless you are bless......i highly doubt it....half *** way-->just put the vtec top-end on your block...done...personally i would stick to one whole motor....don't complicate things.....keep it simple....peace

on my all motor ls/vtec my oil pan gasket leaks, is that pretty normal/ evrthing is brand new,13.5 -1 comp.

 

I don't have any leaks on my ls/vtec. just make sure you get new gaskets and use a lot of silicone

 

When an LS/vtec is done right you don't get headaches or oil leaks. You don't have to be blessed to make a good engine, you just have to know what you are doing. You can get away with your LS pistons but using the Vtec oil pump is a must.

 

Have you even built or participated in a build up of a frank motor?
