how long do you guys think the engine would hold up if i put nitrous
in it, say a 50 shot or so
i have a b&m ffm if that helps me at all

 

My guess would be not that long. First and foremost, do a cylinder leakdown test. If you yield good results then maybe a small 50 shot will be ok. I would also add a nice ignition system to your set-up as well as retard the timing about 2 degrees and colder spark plugs.

 

Koo, yeah i did a compression test (i know there pretty inaccurate )
but it read 140 140 135 145------pretty low

do you run nitrous also or just turbo boss hoss

 

My friend with a 91 civic SI decided to go nitrous at 215k miles on the original motor. Hes been through 3 bottles (ZEX kit 55 shot) so far and no blown engine yet. But of course looking at your compression numbers it wouldnt be the best idea. Good luck with it.

Retard the timing on the intake or exhaust side?
