@chrisdfv how’d the install go? Any problems? And how’s the car feel with this kit on it? Did you end up needing anything that wasn’t included in the kit? Looks great by the way!

Install wasn't bad. I had a bunch of friends help and we got it done over a weekend. Things I purchased that weren't included in the kit were the donut gaskets for the manifold to the head, a new gasket for the water pipe, vacuum hose, some misc tape, and heat tubing. The kit includes a 50ft roll of exhaust wrap.
Car feels great. It's obviously not instant spool like stock turbos, but after 1500 rpm it feels normal under daily driving conditions. Power comes on fast, and the powerband is linear now(I prefer this). I no longer have the crazy mid range torque to just blow the tires off.

I dyno'd around 460/400 on wastegate 15-17psi with very low timing.

that's some nice and linear power right there. nice to see some fab shop start using some real turbos.

Nice!! What turbo did you get with this kit?

I ordered the same kit with a GTX3584rs

@Jonvigil82 was great in helping me get set up.

I was only half joking. Also pretty sure the difference between a ball bearing Precision vs. the equivalent GTX is like 1k if not more. Unless you meant to say GTW?
