Looking for a suggestion for my build. My motor is forged and heads have been wrked over nicely. I had a FAST intake that I was going to use but am thinking about just using a LS6 intake and recouping some of my cash. MY FAST was drilled and tapped for direct port nitrous but never used (plugged). Question is: what is a good TB for a turbo motor that will make 650-700-rwhp?. I have FAST fuel rails and 83lb injectors. Will a stock TB be OK or should I shoot for a Nick Williams maybe? The FAST intake I've read will really be no added bonus...true??

 

Stock TB here, I think lots of people use stock, but some upgrade to the wierd intakes with a TB that bolts on the top with a 90deg deal off the top, thats mostly the super high hp cars though.

 

stock

 

stock, but ported

 

I ran a stock ported TB + LS6 intake, went 144mph no problem. I'm switcing to 90mm stuff now for my 800-??? rwhp setup.

 

i made a thread about this before but do u guys think that the epoxy in my self-ported throttle body will hold up to my 8-9 psi of boost? i dont want that chunk of epoxy to slam into a valve and destory a piston or soemthing.....

 

Mine has for four years.

 

It doesnt make much sense to run a TB bigger than the Piping leading to it. Stock is right around 3" I believe.
