I am looking to get the max out of this motor before heads/cam go on. I have the following:

Long tubes
Full exhaust
LS1 SLP lid setup
52mm TB
Pullies
1.6s
LT4 KM
AIR, EGR, and cat deleted

Chris1313 Ram Air, EWP, and a tune are next. What else am I missing?

Cutout and stickers. Gotta have stickers. And maybe some gears. (The sticker thing was a joke)

Gears! Probably the best bang for the buck out there.

Thanks for the recommendations guys, but just looking for ENGINE mods for now. Already have a cutout, 918s, magnum pushrods. Is it really worth going to 1.7s over 1.6s? If I didn't already have the 1.6s I'd go that route. How about a lightweight flywheel? The car is strictly a street car, it has only seen the track once in the five years I have owned it. I have plenty of suspension done and gears are sitting here at my shop waiting to go in.

I wouldn't really even bother going from 1.6s to 1.7s because of the minimal gain. just my $0.02. Definitely get a tune and do the TB by-pass mod if you haven't already.

Just the rocker swap alone was worth 10 rwhp and 6 lb torque across the board for me. I switched from 1.6 s/a Promags to the Scorpion 1.7 nsa.

I would definitely say 1.7s. Some gears. Tune. Of course the free mods, tb bypass and all. Nitrous is always an option. A frequently overlooked option is weight reduction. I don't even have full bolt ons but with the amount of weight reduction I have done, I still frequently outrun stockish LS1 cars. Of course I have thrown a lot of shit out of the car that most people wouldn't be okay with. A/C, carpet, sound deadening, safety equipment, etc etc. And the gears help too. Haha.

Yeah Stickers belong on a tool box or somethin in yer shop NOT a street car Circle Track & Sponsored Drag cars ONLY!!! LoL But as stated gears & a Stall converter. 3.73s for an auto & 4.10s for a M6 Keep you 1.6s for when you get porting & a cam :) Suspension is a MUST Have too
