wats up people i just recently got a ls vtec rebuilt by a local mechanic all new bearings on da block,,, ls rods arp rod bolt n pr3 pistons stock gsr head with a aebs intake mani i was thinkin of puttin a turbo n runnin 5 psi....would it b safe to turbo dda lsvtec im not sure wat da conp will be n dat kinda scares me....i dont have $$$$ to put lower comp pistons in so if turbo dont werk can i throw a nos system on it???? NE HELP WOULD B GRATEFULL THANKS IN ADVANCE....

boost it man.. i have a lsv with stock internals that i have pushed 5psi for a year and just went to 10psi today

why dont you ask the machine shop that built the motor what comp it is, they will have to know unless its some dude in a garage putting it together. Most likely you can turbo it as long as you have it tuned right after the turbo instal. You can even ad a small shot of nos to gain a extra few hp and lower iat's.

i hope you atleast plan on running e85

why e85? its not needed and not the answer either

i just hope the OP plans on proof reading his post and begins to fix his grammar

with the b16 pistons with a gsr head it will give him like 11.5 cr, not super good with boost. just needs a good conservative tune. e85 will ensure no detonation

If running a B18A/B crank and rods with even USDM PR3 pistons compression is over 12:1 and that is only if the head has never been milled, which is fine for boost you just need a good tuner. The compression will depend on what pistons the motor was built with. Ask the people that built the motor what pistons they used in it. E85 will not only ensure no detonation but you will make more power with it as well over 91 pump gas.

holy hell i had a hard time reading that.

i would not run boost on that motor with cast pistons.

Its all in the tuning. A good tuner and E85 work wonders. Also keep in mind that it wont take much boost to make good power with higher compression. A little 50 trim would be a fun turbo on low boost like 5-8 psi, would be a blast DD to drive. Its not like B18C and B18C5 motors have not been boosted stock before.

to protect him from detonation .
