Rebuild Engine?

[240SX21]

hey all.  well ive starting to make performance upgrades to my car, and i was hoping you guys could give me your opinions.  would it be worth it to build my engine?  i have an 89 S13(2.4L SOHC engine) with 89K miles on it.  so far ive only added platinum spark plugs, apex catback exhaust system, & injen intake.  i want to concentrate more on the engine itself now, but im wondering if i should just install aftermarket parts(fuel injectors, cam gear, etc.), or if i should first start by getting the engine rebuilt.  ive had no problems with it since i bought the car 4K miles ago (except for needing a new valve cover gasket cuz I was leaking oil).  have any of you had your engines rebuilt?  how much did it cost you?  think there's a good chance i could damage my engine if i add aftermarket parts w/o first getting it rebuilt?  any and all opinions are greatly appreciated.  thanks guys!!

well first  u need to plan out the future plans that u want to do to the car.
and u have to stick to them. so, in other words, if u want to run a turbo car. u rebuild the motor for turbo(lower compression pistons, rods, etc.)
but if u want to just have it normally aspirated, then i would have to say, that their is no reason to rebuild the motor if it only has 87k miles. the simple bolt-on modifications shouldnt do any harm to the engine. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

89k jeez. your motor has just been broken in! with that many miles, i'd buy the parts first, then rebuild. you could put a turbo with low boost on that engine and it would be fine as long as you have your engine checked for leaks and cylinder compression.

thanks fellas. &nbsp;actually im not looking to go turbo, just upgrade the engine. &nbsp;im looking to get an all around car(sound, looks, & performance) so i cant afford to go turbo(side note: im only 17). &nbsp;i got my system all done & now im working on performance. &nbsp;thanx for the advice guys. &nbsp;i guess ill wait till i hit at least 100K to get the engine rebuilt.

even 100k is to early to rebuild i think <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wow.gif" border="0" valign="absmiddle" alt=':0'> that is if your car runs fine. i know you've just got your car but most nissans will last forever. only rebuild if your engine dies, otherwise you'll be wasting your money if you're not going turbo. i have 187,000 miles. my engine could use an engine rebuild (cly #4 is barely oily sometimes) but it runs just as good as the day i bought it with 132,000 miles
