GSR engines' weak spot?

[stealthy]

heres the deal. i want to boost my gsr, but i cant decide if i wanna boost it stock or throw in some pistons and rods. whats the weak point in the motor, is it the sleeves? i just dont want to spend the money on pistons/rods if its the sleeves i need to worry about, in which case i would just boost it stock and then later on do a full sleeve and build. i just got a gt35r and im trying to figure out where to go from here

personally if you still look to build for later i would just throw a kit on the stock motor and run at 9 psi all day every day and you'll be just fine and should put down upper 275-300 whp, with good tunning and set up. but with rods and pistons you can go with a dual stage boost controler and do 9 psi daily and filp it up to 15 psi for your weekend worrior. but if your more interested and worried about the safety go all out and get it sleeved and built.

over building an engine is the source of reliabilty. if you can afford it now then you might as well build it. why wait to see if it throws a rod through the block or something if you have the money and can spare the downtime on your car now.
