ok my engine is an 11:5:1 compression forged lt1
gasket matched heads-polished
gasket matched intake manifold-polished
220/230 at 510 lift cam
1.6 roller rockers
stock fuel pump
stock injectors
stock throttle body

what do you think i should get next
fuel pump, injectors, or tb

 

You might see some small gains with a TB upgrade. I didn't see any exhaust or suspension upgrades in your sig, if you haven't done any of those upgrades, you should see some nice improvements in both those categories.

 

slp headers, random tech hiflow cat, and hooker catback
vogtland coil overs in front, vogtland springs with koni adjustable shocks

 

I say get rid of those slp headers man (I think all they made are shorties right?). Some lt's should net you at least 20 hp. Then a tb then youre talkin, injectors wont get you more power (unless your maxing them out) but you may be above your duty cycle at that power level)

 

I would do a tb and long tube coated headers.

Then I would go with sfc's, lca's, and torque arm. If you car is lowered and you don't have an adjustable panhard bar you need to get one of those also.

 

thanks for the replies guys im about to order a tb, and im looking for lt's

 

id also do a fuel pump.. partially as a security measure. and also if you havent had the car dyno tuned.. i would
