i have a ls/vtec teg with a gsr (p72) head it needs a new head gasket but i plan on turboing it but i also have the stock head that the guy i bought the car from and he said "the compression is too high for boost". so what do you guys think should i stay with the gsr head or go back to non vtec and boost that? what type of things would i have to do to get the compresion low enough for some good power?
thanks for the help in advance.

 

Personally I would stay with the gsr head, no use in un-doing the work. Ls/vtec will make more HP in general do to the fact that the vtec heads flow a little better.........Stick with the ls/vtec you won't be disappointed when turbocharging!!!

 

ok thanks what would be a safe boost level from a .57 trim?

 

I would start w/ 7psi and go from there. Remember though, too much power and you'll def. be risking a blown motor. Those LS/Vtec's don't hold up without the proper build, so be careful.

 

10-12 psi on 57 trim

 

i would run 8-10 psi... 8 psi to be on the safe side.. 8 psi isnt that bad on a gsr.. ls/vtec more torque though eh? so that would be nice..

 

ok thanks guys. i want to get the tounertoys rods for this buil what pistons would you guys recomend and would hastings pistons be ok? and will oem head gasket be ok or what type of head gasket help me get my compression a little lower?

 

cp piston here, stick to oem head gasket, what is the compression of your piston or what pistons are in the block??

you can go higher than that, somewhere in the mid 7k range. i rev stock ls motors to around 7400 no probs

 

WE just did a ls/vtec turbo set up yesterday. running about 8-10 psi @ 10 psi it wants to lean out so im picking up a 255 WFP and we will se what happens. Other than the fuel issue it runs great. The head has been ported tit seats, retainers, bigger valves on intake side stock on the ex sice, and springs. Oem HG with copper spray. Stock bottom end b18a w/ a little over 70mies.

lsvtecs are good base engines,but should be built correctly...

im boosting my eg hatch t3t04e.57trim 13psi low and 15psi hi setting on my boostcontroller and i rev pass 7k..8300 all day everyday...and been boosting for almost 2years now and its my DD...btw the block is all stock...

 

ok so stick with the lsvtec. oem head gasket? do i need a ls gasket or a gsr gasket? can i keep my a/c? thanks for all the help guys.
hey dturbocivic i was born a raised in lansdale, hows the weather up there now? i want to drive my teg up there in the summer how strick are the cops on exhaust and height on cars?
