Well you have to work at it but yes, everything he listed will work on your L67. As for Input Shafts...Have Dave install them when you get a Triple Edge Performance Transmission
*RANT*I doubt it would cost $15,000 but from after talking to Tom and Paul about the Whipple setup and Robotec on here (WHO HAS ONE) you jsut have to know how to tune for it. Reason people blow **** up is because the Whipple creates SO much heat...hence why a Intercooler/Meth or whatever form of cooling route your going to use has to be VERY efficient. Tom ran a Whipple on his stock GTP with a Open cone intake and tune and put down 330HP. Only deficiency there is to keep KR levels down he ran a 4.5" pulley. Using something that large put boost levels too low to make the Whipple work well enough into it's "sweet spot" since the Whipple is made to make LOTS O BOOST, I've had buddies with them on Cobra's running upwards of 22+psi, granted they can handle it. I'm just coming from the standpoint if I had Ten Grand to waste...I'd put it into a Forged Bottom End, Heads, Cam, IC/Meth, 60#'s and get the damn Whipple. I love the sound, I like the idea and you can't argue the thing makes power. In a way I like to compare it to the NIC Cam. They both make crazy power but at a risk...the Whipple is very hard to tune for just like the NIC Cam, which many people (And even ZZP contested to it) that an improper tune with take out a car with only a 3.4" pulley on it...it is just the fact I think it is a really cool concept and would love to do it someday...I just suggested it thinking I'm not the only one who would want to do it, but meh...whatever.*END RANT*
Heads, Cam, IC/Meth, TB, Headers, Tune, Smaller Pulley, Intake, GenV, Injectors, and a Tranny...
Details is up to you. Heads can be pricey so I'd look around and make sure you know who is doing them...that is one thing you NEVER want to skimp on if your gonna do a build. Intense-Racing does great head work too IMO. Ed Morad (Morad Parts Company) can also help you out with any 3800 part you might need.
