I recently bought a 99 TA and am looking at going with LQ9 heads to lower the compresion and stepping it back up with spray I will be changing the pushrods at this time also so how much can it handle SAFELY being the key word. And also before i get the heads and rods put in how much will it handle.

I would leave the heads alone nitrous loves compression. As far as your question with fuel system upgrades trmin8r is running 200 on a stock internal motor and seems to be doing just fine, how ever most speed shops and manufacturers say 150...split the diff go 175 with a fuel pump

If you plan on pulling the heads you might as well do some porting to them yourself.
