I was wondering if it would be alright to spray a 75 shot of nitrous into a car that has 147,000 on the clock? It has been well maintained and still runs strong. I was looking at the Zex systems and they look like they would be the safest system. Or would it be better to do a PI Head Swap, I only have around $600 to spend right now. Any comments would be greatly appreciated.

I would recommend the PI swap, simply because the power you gain will always be there and you won't have to keep getting the bottle filled. Thats just my opinion though

Can I get the swap for $600 or less with everything I need to do the swap? Thanks!

yes you can get all the parts, but the install is alot more expensive. If your doing it yourself then im jealous and wish I had as much mechanic ability as you do. I wouldnt like spraying a car with that many miles if I wasnt prepared to pay for a new motor if anything was to happen. Normally a 75 shot would be completely safe, but if there is anything in the engine that is close to coming loose, the nitrous will surely find it faster. I would do the PI swap simply because you are getting new heads and valvetrain. Thats whats normally seems first to show wear on any car. Honestly, you could find a decent complete engine for not much more than what you have now. I bought a PI engine once for $500 and it only had 47,000 miles on it. It was a deal from a guy that lives nearby me. He was asking $1000 at first. If you could do that, you would have something you could add nitrous to later and itll keep you running good longer too. $600 will just barely buy a nitrous kit. Then you need possibly fuel pump *questionable*, bottle heater, gauge, window switch, etc...so I really think youll end up spending more on it plus you have to get the bottle filled....I say get the whole engine
