I recently purchased a 95' 240sx. It has a few modifications to it such as a short air ram, greddy exhaust, modified spring (don't ask I don't know), and supposidly a greddy header. The car has 150k miles on it and as far as I know, its has never been rebuilt and has completely stock internals.
My question is, if the compression checks out, would it be a green light to turbo it? Also, if there is a slight compression problem, would that make it more likely to blow? I am just asking cause when I was looking at the KAT hp poll, someone was running 10psi and popped the engine. I plan only to run 8 psi as a daily driver. My goals are eventually 300whp, but a round number like 200whp will make me happy as well.
I know its been said on the forums that its not psi that ruins engines but horsepower.....but I don't really comprehend that....but anyways....

Re: Pre Ka24de-t question (amdpowered)
Think of this if you use nitrous to boost your horsepower your putting more stress on the engine to produce more horsepower. The amount of horsepower your producing is proportional to the amount of stress the engine is going to endure, also the engine is only as strong as its weakest link in this case pistons, the pistons can handle up to about 300hp in stock form, with a GOOD tune and proper care will still be reliable. So I guess this still didn't answer why the same boost don't matter? There are several reasons such as efficacy but the main one is prob that different a/r ratios and wheel sizes can move more air at the same psi, so its the volume of Air that matters more not how much it is compressed. IF that didn't answer your question SEARCH noob its located at the top right corner of the page, use it and become its buddy j/k and welcome to NICO
BTW dude, 300 is just as round a number as 200 one that wouldn't be so round would be 267 or something</sarcasim>

it's not the HP...it's bad fuel management that kills a motor...amdpowered wrote:I know its been said on the forums that its not psi that ruins engines but horsepower.....but I don't really comprehend that....but anyways....
but good compression is key when turboing a motor....if your results aren't strong consider things like, new headgasket, piston rings remachined top end, etc.

I'm at 140K now... over 25k with this turbo. The engine will hold fine long as its good to start with.
