Mods?
Sorry for the stupid question but I am still new to ls1's.
Thanks
with hundreds of thousands of threads and topics....you don't think you could do a little reading first?
SEARCH is your best friend.
i suggest reading the first 10 pages of threads (scanning for the pertinent ones) of the LS1 internal and the LS1 external sections, as well as the suspension section.
search anything you don't quite understand.
99.9% of things have been asked....several times...usually in the past day or at least week.
welcome.
oh and make a signature telling us about your car, year, type, mods, goals...etc
- supercharger
- changing gears in the rear end
- high stall converter (I know you have a manual)
- gigantic cam that won't run well at low RPM

For the OP, I would do just bolt ons. i didn't see what year your car was, so I will just throw these out. Lid, Ported TB, ls6 intake, LTs (emissions permiting), ory/duals, catback w/ cutout. Nice gains, wont kill mileage. Gears if you want to accelerate quicker, but if you drive 75 mph highways everyday, I would reconsider. Oh, after everything is installed, TUNE. Best way to get the most out of your mods, and mileage and drivability. Hope this helps.
Start with bolt-ons then work towards the bigger mods. Just do your research before you start and have your goals in mind the whole time.
