I'm looking for some type of upgrade over my stock LS1 trottle body, BUT is it even worth it? i will nto be upgrading to a LSX intake so the 90mm is out of the question, possibly one day i'lll switch to a ls2 intake a TB someday but for now i just want a little bit more. Supposedly the stock TB is 75mm but only a 72mm without some porting work. Ive found a few but i dont know how good any of them are..
- BBK 80mm...$300
- Accufab 75mm...$400
- FAST 78MM(some say it will fit stock intakes...)...$400
- Thunder racing ported stock TB...$150
- Lingenfelter ported stock TB...$100
- MTI
- Holley 80mm
- OR just try porting it myself (i have 2 housings in case i screw up)
You would assume the BBK to be the best choice but im hesitant of BBK products(dunno why though). I may try porting 1 housing i have, and if i screw up, i think i'll go for the lingenfelter one. What do you guys suggest?
