I have a nice little project going on. I have a 240SX with a LS1/6 its a 12561168 blocks with the LS1 heads from a 2002 Fbody.

I am paired up with a built TH350, Shift kit, B&M Torkmaster 2800 Stall, 3.69 gears, I could go to back to 4.08 if need be.

I am not an engine guy, I know my way around and how to work on the normal things, but when it comes to building them up I dont know the pros and cons of what parts work well with others.

I would like to up the power some, I would like to make 400-450 RWHP

Right now I have
Dual Borla XR's 3.0 in/out, and an Xpipe all three inch pipe, no cats
I am using a fuel cell with a MSD 2225 inline fuel pump, Holley Regulator
Ported and De-Screened MAF
Fast 90mm Intake Manifold

Looking to go to 42# injectors, FAST fuel rails

I have a lot into the car and much work to do so I am on a budget, What would you do to meet my goals. Its not a DD but its a street car, mostly for weekend drives, show, and having fun. I was thinking about getting a set of LS6 heads and getting a port and polish, and a Thunder Racing cam for starters. Are the LS6 243 heads a good choice to get me there, if so what should I do to them and what cam should I pair them with.

What do you suggest?


I got a set of 317 Cast heads for free off of an LQ4, but I dont think I have a use for them

Go ahead and pick up a cam and a valve spring kit and install them, depending on the size of the cam you can make great power. I would suggest a much larger stall for a cammed car though.

So just stick with the OEM LS1 heads?
No porting needed?
Rockers?

Any cam suggestions, iv been looking at the Thunder racing cams but there are too many choices. But they have a package deal.

"Thunder Racing LS1 Cam Swap Package w/ Dual Valve Springs Includes:
- Your Choice of Thunder Racing Camshaft
- Dual Patriot Gold Valvesprings and Ti Retainers
- Thunder Racing Pushrods (7.400)
- Valve Stem Seals
- Additional spring options available below"

And I was thinking of going to the 3800 stall TCI StreetFighter/Super StreetFighter

Too many cams to make a recommendation. Do you want the car to have great street manners?

Well I am looking to have a fun car I can run the 1/4 with time to ime, but its mostly for going to shows and having fun on the weekend. I want it to be aggressive, but not to the point where its gonna be stalling and can be cruised with out mashing the gas
