Just an FYI as I took a recent trip out to see our friends at Evolution Motorsports and amongst other things I got to get a good taste of their new GT660 kit. We've always been a fan of the GT700 kits and have been installing them since 2005 but in my mind anything after the Stage II using the K24s just didn't cut it. The K24s aren't really fun to drive with. The 660 kit sits right there as a logical step-up for people with Stage IIs looking for more power. Built-upon similair building blocks to their GT700 kit, EVO's GT660 kit incorporates their newly designed Garrett turbo chargers. The red 996TT (Steve's?) we got a ride in was spot on the 660 hp / 652 tq On Pump Fuel Mode 91/93 Octane after the mustang dyno AWD conversion (I got to see about 30 dynos before my ears gave out). For any cars already with an exhaust and a few other parts this kit works well to incorporate what you already have. The stock fuel system can take a little more than 600 but really starts to max out (wish us 996tt'ers had the 997TT injectors) so having the higher-flow injectors bring the duty cycles back down to where they should be
There should be some new announcements from EVO shortly. I got to drive in another car with these afformentioned turbos and again the spool-up is much improved. Let's face it none of us really like those laggy K24s...
Anyways, we're all systems go on these kits now. Contact myself alex@sharkwerks.com , mike@evoms.com or stephen@imagineauto.com (depending on where you prefer to go or who is close to you).

I think in the GT2 they feel much mroe seamless and "right" so to speak. It's a different platform but in the X50s/Turbo S' they're not my favorite... These turbos spool 300rpms sooner and the car just feel more responsive down low. When you're driving mostly around here from 0-80 quicker spool is more preferable I feel. On the track, K24s are obviously fine and in the GT2s case more "controllable" in terms of how they come in...

alex...with that type of horsepower increase don't you really need to also upgrade some of the engine/transmission internals....how much horsepower increase can the stock engine safely handle...and i mean for street and not track use..? this has always been a concern of mine. one thing is the cost of the kit, but most importantly what would it cost to improve basic engin internals.

Building the engine would really vary on the parts used and who does it (labor rates). Most of the engines we've build have had Carrillo rods, ARP head studs, EVO head gasket, GT3R oil pump and misc stock replacement parts obviously. No doubt it's expensive but unless you had 70K miles on the odo I wouldn't see the need for it at 660hp (crank).

I am the owner of the first GT 660 kit. I really don't have any experience with 996tt. This is my first Porsche. I bought my car stock with 8K miles and went straight to the GT kit. So basically I have put over 3K miles and it runs stronger than ever. I am still learning how to drive this car which is very different than my M3. I need to take it to the track to feel its limits and personality. I am very satisfied with this kit. The main reason I chose this kit is how easily upgradable it is. I can get to the GT 700 kit very easily. Here is a vid of my impressions.
