After reading the title of the thread I was sure it was going to be a link to E-bay LOL!!!

Fair play to the chap who's building that, he must have a fat wallet!

that's gotta be 100K, why didn't he just use a Mitsubishi engine?

Hey Ashy, email him and ask if he's using a T2 flange :laugh:

I can't really find any info that I'd trust on that turbo, but what I've seen puts it at around GT3071R size - which is pretty small for all that power.

First thing I spotted. Crude to say, but yes from the look of it it doesnt look big enough.

sounds about right, if it's designed for WRC it'll be optimised for high pressure ratios (due to the restrictor) optimised around 30lb/min. That small inducer is about the size of my Gt28R which kinda backs that up. I bet that'd be an interesting turbo on a GTT.
