hm.. this is kinda both engine and FI question... but i think i'll just put it here:
I had a compression test done today just to see how my engine is doing... 1st-150 2nd-150 3rd-140 4th-150 brand new engine would be approx 180 or so psi... but my numbers are still acceptable right? i think anything above 100 is fine for stock engine and anything above 130 is fine for turbo engine? my engine has about 100000miles on it... even though these numbers are acceptable... is it necessary to take a further look into it? with these numbers would it be safe to go FI?

get your own kit and do the test yourself. also, google "compression test" and read all the howto's on it. a lot of things can affect the numbers, like if it was done hot or cold, if the gas pedal was at wot, if the efi fuse was pulled out, etc...
your numbers seem ok. the only one i would doubble check is cyl 3. the idea when doing the test isint to really get all high numbers, but to get numbers that are very even across all 4cyl. a leakdown test would also be a great idea.
