you'd be better off sticking a 2.5 engine in there first mate, and putting the nitrous on to that,
not only will the 2.5 give you an instant BHP upgrade,(pluss it's a direct fit) so you can put more nitrous in to it, but.....
you would also be better off if you done some engine work first, cam/chip/intake/head work/lightend flywheel/ etc etc then the same goes, you would be able to put more nitrous in,
if you a bit strapped, just stick a 2.5 in and slap 70horses of nitrous in to her, you can pick up a 2.5 for cheap enough these days
if you do go for nitrous, please make sure you put the correct jets in for fuel/nitrous, or you engine could just go POP, if you need any info, instructions, help, just give me a shout and i'll try my best to help you out matey
