I have a set of ETP 225 heads with a FAST 90 and FAST fuel rails that I am getting ready to install on my LS2 06 GTO (A4).

My question is will my current cam be sufficient enough for those heads. My cam specs are 232/234, .595"/.598" 114 LSA. My other supporting mods are SLP LT, Borla Catback, Yank 3600, LPE CAI, 160 thermo, and a 125 dry shot, Cobra Blue top injectors.

Any feedback would be appreciated.

 

Yes that cam will work fine with those heads and intake. Will pull like crazy from about 4200-4500 and won't stop till read line.

 

So will that effect my bottom end efficiency if it will only pull from 42-45 rpms? Or am I not reading it correctly

 

?? Anyone

 

With that Yank 3600 stall it should pull like a rocket. It will be a strong street setup and with the gas, watch out. Those heads have good mid-lift flow and a very good intake to exhaust flow ratio so she should run real well. I would run the cam you have installed right now. Your torque numbers should be quite good and that's a plus with a car the weight's as much as your does.

That should run very good... take it from someone running ET heads

 

I'd say you should be doing pretty well, though I would have gone with the 205's unless you had more than stock cubes. The stall is going to help you get into the power band in a hurry, so your bottom end shouldn't be much of a concern.

Just stay away from anything resembling a cat in the street (Inside Joke), and invest in some new radar/laser protection technology. You already need it, now you'll need it more.

 

Thanks for the input. I cant wait to get them in the car I will update with numbers when Im done

 

Got the car done and needless to say I am extremely impressed with the numbers that it gave me. We will see how they convert to track numbers here in the next few days.
