from what i have read, the motor should be able to stand up to a 50 shot. 75 has been done, but generally isnt recommended. 100 shot has also been done, and the motor was not at all happy about that.

if you do go with the nitrous, i am sure it will probalby shorten the life of your little spi (and your clutch)

about how it feels? i wouldnt know, never tried it.... but bet its a kick in the pants.

Well, the stock "motor" can handle about a 150 shot, but the stock engine managment can only handle about a 50 shot.

Get a nitrous tune from either Wayne at hypnotic illusions or Randy at FS, I have seen a thread on here where a guy was running N20 and it blew a hole right through one of his valves b/c it was untuned. Nitrous creats hot spots and it will keep hitting that spot and make it weaker and weaker untill it breaks.

I think the SPI will hold up to it fine and if you run a tune with it I cant see damage happening from it any time soon.

Yeah it's worth it. If you spent $600 on all the normal bolt on crap you'd only gain like 9whp.

You'll be fine with a 50 wetshot, just get some copper plugs that are a least one step colder, and run at least 91-92 octane gas.
Then if you want to run more then that, or want to run crappy gas you'll need some tuning.
