Well . . . how much added hp do you want? You can buy kits that come with jets for 50-125 hp and you can set it as you want. Just do your research before you buy and install the kit. More damange is done by nitrous+ignorance than the added strain of nitrous alone.

I've read that 75hp is pretty much max on an older stock motor, unless you rebuild it and get it in like new condition first, I wouldn't even add nitro. Unless of course you can afford to have it blow up.

i'd stick with a 50hp dose unless it's been rebuilt lately.

FYI: IT's NOT NITRO its , Nitrous Oxide or NOS/Nitrous a very large explosive differance.

A compression and leak down test should be done before thinking of using Nitrous Oxide unless you have a spare motor to put in. Spinning a old bearing is easy to do.
I would put the money in a good tune-up with some performance parts. What works for one doe's not work for another.

nitrous

If it's a stock non-rebuilt engine i would not chance it. But for different reasons. Your engine probably is full of carbon deposits in the chamber. These deposits will become a source for hot spots on the juice witch Leeds to detonation, witch in turn will cause a burn down of a piston or a torched head gasket....

Yes, a new cast bottom end can handle quite a bit of abuse. But with something that old and that wore in I would be hesitant to chance it seeing as its probably his daily driver and he probably doesn't have another motor for it just in case.
