i got a 98 GT and want to do the PI swap, what all do i need to do or get? will the fuel system and computer still work?[/align][/align]

Chris98Gt

Fuel system and computerwill work, but I'd suggest getting it tuned afterwards for a few moreponies. Try andget a set of late 01-04 pi heads and all you'll need is a head change kit, a pi intake, and a pi coolant line that goes around the pi intake instead of under the npi intake. If you can get a npi aluminum coolant crossover plate with 2 temp sensor holes swap that one onto you new pi intake so you dont have to drill and tap a new hole. If you can only get a set of 99-mid 01 pi heads you will need new valve covers and a few larger timing case cover studs, and the chain guides will only be held by 2 bolts on the passenger head. (thats no big deal tho)

how much was your cams? and where did you get them? is it a naticable differance after the swap?[/align][/align]

I got my cams and valve springs from modularmustangracing before I knew about modularpowerhouse. I think it was around $900 shipped to me. I don't know how much a difference they made since I did everything at onceexcept the procharger,but after the swap I was out test driving it and I was on the limiter before I knew it. It definitly pulled up top much better. They also have a nice lope at an 800rpm idle.

ok next question, what is the rev limiter set at on a stock 98 gt? whats the highest safest RPMon the stock bottom end?

Chris98Gt

Stock limiter is 6000 or6250 I think, Tim set my limiter on 6500 after he tuned it, I wouldn't turn it any higher than that since stock stuff won't make power that high and it won't hold up long.

ok just wondering cause the intake i was looking at makes 23 more hp than stock at 6300 i got a SCT and i think i got the limiter set at like 5500 cause i wasn't sure and didn't wanna blow it up[/align]

Chris98Gt

A stock npi car isn't making any good power after that anyway so you weren't hurting yourself.

ok i set it there cause thats about where i felt it quit pulling
