I don't have one myself, but every person that has got a UR kit loves it. I have never seen a bad review with UR, and they are known for superb customer service.

I would stay away from Agency Power and Crawford.

I have seen Perrin kit and it is nice. Heard great things about UR.

I saw a Perrin kit that Crucial was coating yesterday. It was pretty sick. Doesn't Gruppe-s have one as well?

You might want to check out Kingpinperformance.com and slowboyracing.com. I believe Kingpin's kit is a rotated mount--featured in Modified Mag. Slowboy racing's GT35R turbo actually fits in stock uppipe location--owner has his ride featured in the website with supporting mods. I personally went with a FP Red--really big turbo that also retains stock location; didn't want to have to buy entirely new downpipe and uppipe combo all over again. Good luck with your search and decision.

From what I heard, fitment on Kingpin kit is very poor.

I had a slowboy racing GT35R in stock location. i made 508Whp uncorrected in Denver(5280feet). that was on stock block. I had full boost at 4200rpm. i would HIGHLY recomend this turbo!!! now i have a Garrett GT4088 (GT40R) on a fully built cosworth motor. the car will be tuned a week from today all try to post some dyno charts. if u have any questions about the turbo or anything else in general pm me and all give you my cell. I know the motor and tranny builder from easy street so if you need advice im in kind of a place to give it.
