What prices are we talking for both complete kits?

Like 1400 compared with 1900 I think

But that's with a large hotside pipe.

I paid $2400 for the 2.2 kit and hot side piping from Kevin (ProcessWest), I also picked it up myself though to save the shipping, plus I was very excited to install it.

Theres $100 difference between the pw stg 2 and the nizpro stg 1

Mika, did you polish your cooler?

Nah it's not polished. When I installed it I tried to get it as centered as possible..

I'm assuming your is the 'raw' state then Mika, looks awesome.

I installed a nizpro coller and adapted a proccess west throttle body relocation kit

The result was 360rwkw @ 15 psi std motor n nizpro 4 inch exh ,just my experience.

Both coolers are good enough for easy 400kw just depends on which look u like.

I ended up purchasing the process west stage 2 and a hot side pipe, im sure this will be ample for my requirements. Keen to see photos from others! Also, peoples experiences with under battery intakes? Iv heard mixed reviews?

Btw. Kevin is a really nice guy at processwest, very happy with his service.

Tofski what other mods are you using to make that power?

I run the PW 2.2 with the udp, car has seen as high as 417 rwkw on the Autotech dyno, has run a 10.91 @ 131.9 MPH and has seen a highest MPH of 134.56, factory turbo and manifolds on e-flex.

Would highly recommend this kit as it works well.

Tofski what other mods are you using to make that power?

Other mods include wasregate mod ,4' nizpro exh ,injectors pump,4' intake from plazmaman and cooler ,tuned by cv ,could got more power but wanted to keep it safe and traction is hard to get on the street as it is even with semi slicks .its a ex chaser bf 2 std motor unopened with 110k kms ,btw its my wife's car with 2 baby seats in the back .To make good reliable power all you need is remove all the restrictis as possible ,make the motor breathe easy and power will come after it all about efficiency.
