i've read that you should prepare your engine for a turbo... now i have a gsr with 135xxx on it and was wondering what i should do to prep my engine to handle the turbo...also what type of turbo would you recommend ...thanks .p.s. not an unlimited budget haha far from it but i dont kno my limit now so dont ask just in reason...

well thats alot of miles to slap on a turbo. i would rebuild the bottom end first. put in some new pistons, rods, rod bearings....the whole 9 yards. Also get a Block Guard for some extra safety.

ur gonna need to upgrade ur fuel system too, bigger fuel pump, injectors, a FMU adj. fuel pressure regulator.

a simple T3/T4 turbo will do u good justice

the turbo size will depend on your hp goal.
if your looking around 350whp+ i would get je pistons(9.0:1cr) eagle rods,
new valvetrain(port flow,ferrea,supertech...) send your block to get sleeved.(i reccomend darton)
and get a gerret t3/t4 t67 turbo and hondata es200. and your set.

thanks for the info... but do u guys even think i should put in a turbo with this many miles....or will the new pistons valvetrain and everything make it realiable.... also how much do u think this would all cost thanks..

miles dont matter if your rebuilding your motor.
je pistons&eagle rods are the strongest for the price you pay. the pistons are like $550 the rods are like $450
supertech vavletrain is around $500 hondata es200 is about $700
thats all you need if your looking to stay lower than 350whp
if you want more power then send your block to darton to get sleeved thats $1500.
if i were you id just buy the turbo and hondata right now, and just save tell you have plenty of money to do the rest.

alright thanks that sounds good ....i have a verry limited knowledge about engines but do u think with help from my friend and his dad ..who works in a garage ..that i could put these on myself and then just have it tuned at redline motors or something..thanks

also gsr's have high compression right so would the rodsa nd pistons and everything lower it for turbo or what ??

Ur gonna need to buy low compression pistons for your motor. If ur going turbo, but will only run small amounts of boost like 8-12 PSI then u should get some pistons with a compression ratio of about 9:1

i donno about 8 - 12, on a stock internal motor. 7 is more than likely a max for stock b18. You might last a couple months with anything over 7, but dont plan on it lasting long :) <<--- Trust Me Ive Been Through It. Of course I do like to give it hell. Do the build before you bolt it on, otherwise use low lbs.
