I have the head built on my turbo LS (dual springs,retainers,3 angle valve job), the block is completely refreshed with new ITR oil and water pump, with endyn pistons. How do change the factory limiter so I can reach my highest HP peak. Do I need a new ECU?

 

I would recommend Hondata , do a search on it.

 

You probably wont make much power past stock revline with stock LS cams, but who knows. You need to chip your ECU one way or another, I like uberdata personally. its free. http://www.ecimulti.org/uberdata.

absolutely. The cams will be your weak point, anything is better than stock. use uberdata.

 

So how much power would he see from better cams at higher RPMs?

 

cams are the weakest link in a LS head. thats where all the power will come from, stock ls cams suck!

 

don't even bother changing the factory redline yet until you've strapped your car to the dyno and know for sure that you're making power past stock redline. if you haven't done so yet...then just stick to stock for the time being.
