Well to get that HP, lets see. And note you can spend ALOT less on this stuff, but I bought good products.
JLT= 150
TB= 180
plenum=140
E Water pump= 300
U/D pulleys= 140
LTs=500
X pipe=200
Catback= 350
VT stg 1 cams= 549
windage trey W/ gaskets= 100
Tune=350
Chip I bought well before tune (wasted money really)= 325
About $3300. If you get stg 2 cams + 200 for springs, you would make about 300 or maybe a hair more.
Now with EVERYTHING including rims, gears, tubular K member, shifter, ect...I spent about $5500. Basically id have a bone stock GT with a 9PSI KB on it + then would need a tune from MPH =600. Then you will want gauges to keep an eye on everything (good 2-300) Im guessing it would make about 365RWHP cool. Hot on the street would be closer to 350. By the time you dial in the KB and get everything safe you will probably be looking at around $6500. Plus my car would weigh around 3500 vs 3250 now.
I honestly dont think it would be much faster, id say it would trap 110-111 if I was lucky. Would run like a stock terminator. (they go 106-111 down here...and they may be modded) So im happy with the way I went
. I have a good looking car that stands out and is pretty darn quick.
