All he has to do is get bigger fuel injectors and higher volume fuel pump and he will be giving that Evo700 a good run. All that and no internal work.
Honestly I didnt feel that much lag when I had the car after Protomotive did the work and didnt feel like it was lagging badly at all. All I felt was the constant rush of power and the rear end wanting to slide on me when shifting to 3rd until I got the tires warm. I was told that if I was running race fuel to turn the boost up to 1.3bar even a bit higher and dont know if Joe did that when he dynoed it.
All I can say is that before and after were like night and day, the car was sick fast stock but after the work it was ferocious. I have never driven a Evoms 700 Porsche so all I can say is what my car felt like to me "seat of pants".
I can only imagine what VRAlexanders, Craigs, and soon Markski's car feel like.

All on STOCK internals

Maybe Sharky can chime in here about the spool up of the GT700 vs. the K24s.

Garrets are great turbos.

Joe,
I am willing to bet that if you left your combo how it is and gave the heads to McKenzie for an extreme head work job, you would gain over 100+hp..

With stock K24s obviously there's more lag and when the turbo hit it feels less luck a punch in the back (this is with a 600HP kit that I'm comparing it too) and you spin a bit in second and the car feels less threatening over all. As I said in another thread any GT2 with a GT640/700 scares the poo poo out of me.

If the voltage was/is low enough it certainly could? You'd need to hook up a voltmeter to it...

GT3 heads flow more than OEM TT heads. That being said, there may well be room for even more/better flow from a GT3 head.
However, I am not sure how much of a gain would be achieved. In a TT, the gains are realized because the larger turbos push more air than the OEM heads can efficiently/effectively flow, such that the heads restrict power. I don't know if porting TT heads in conjunction would K16s would provide any meaningful gains, as the OEM heads likely can flow the maximum air pushed by the K16s without restriction. Likewise, if the GT3 heads can handle all the NA air flowing through them, I'm not sure if porting the heads would produce meaningful gains.
In other words, I am not sure.
