I will try to answer all the questions here.
The lip is the street concept do luck style front lip. I called em up and got a great deal, the fit is great and it looks super.
I am not going to touch the drivetrain yet, next winter will be the motor, then after that I will look at doing the driveline.
The manifold is part of the kit. You would have to contact ISP in regards to the manufacturing aspect of the kit. They made the DP at the sop for me.
As far as the 303AWHP number, that was when I only had a few things done, with the stock turbo. I updated my first post but I will also put it here again. I went to turbotrix today, and came home with 439AWHP. I have attached the dyno sheet on the first post, and will put it here again.
I will try to snap a shot of the lip for those of you who wanted some close up's.
I leave tomorrow for Texas and wont be back till next week. So I may not get to it till I get back.

The pull is crazy! I wasnt expecting it to be so strong. I have to watch the RPM's now, when I hit full boost it is a completly different animal.
Now I understand why they say that the 35R is the best way to go.

Lookin' good, Caelin. I think you should go ahead and do alky, because right now, you're not making much use of the GT35r. You have less torque than my little ole stocker with stock cams, so it's probably not the most fun thing to drive. However, with some alky, you will be up in the 500-550whp range with over 400wtq on a daily basis...

In any case, what I was trying to figure out was what the lag/spool-up looked like. Best I can tell it's hitting 23 psi around the low 5000 rpm range.

Also I forgot to include this. The turbo is a full t4 so it will be a little lagier than usual. However for my driving style I dont see a huge difference in drivability. I usually put around town anyhow, and get into it on the hiway so this set up works out well for me. I hit full boost around 4800 rpm.

I agree with warrtalon,,, its tough to dyno a turbo like that on pump gas. That turbo wants to see 30+ pounds of boost to be happy. Im actually surprised the car made as much as it did. i normally see low 400's to high 300's with GT35's on straight pump. I think meth or race gas might be in the cards..
I like the kit though.. Spool up was nice .. overall they did a great job on the car. Good luck
