Just returned from an 18 month deplolyment and have around 1600 left to spend on my baby, 98 gt vert with 110,000 miles custom gunmetal paint and intake, 4:10 gears and thats it. WhAT NExT
When I did my PI swap, I got ported heads and intake and the PI cams for about $800 if I remember correctly, from a forum member here. They were off a '02 GT with like 20k miles and had just been ported w/ a valve job. For that price, I couldn't pass 'em up. Then you can get a PI swap kit from GEF, find a buddy and do the swap over a wkend.
You should buy a short throw shifter first. I recommend MGW. Next, midpipe, then SFC's, then the PI swap. If you do the PI swap, you should go ahead and buy comp or VT cams.
