Intake Manifold Help
Now that i got the full exhaust that i want im going to go with a new intake manifold as my next mod. However ive run into a snag... Im currently deciding between a 78mm intake and a 90mm... if i go with the 78 im going to go with the slp LS6 manifold (as of now, any suggestions on that?) and if i go 90 im obviously going to go with the LSX.
How much of an advantage hp wise will i get by going with the 90mm set up? are there any other special things id need other than a new throttle body?
People on here have had good success with the FAST setup on a relitively stock car. But IMO its a bit overkill especially since it will run you over a grand.
I say keep it basic and go with the LS6.
