They might be for cars, they might be better than normal esc cossie T34s, but il put money they not got the 3bolt exhast flange (If this for the american market it prob got a 4bolt flange, or a 5bolt thing that needs a turbo elbow similar to what ERSTs have, and many jap cars have), not at all suprised if the manifold flange is a bit different (prob a T25 one, most are), and youd want to know what the compressor side of things is, tho thats PROBABLY better than a esc cossie T34 one as most T34s use big T4 comps.

The ex and manifold flanges arnt a big deal to get adapted anyhow, bit of cutting n welding...
