I got a magnum 80 sitting here now I'll see what I can do about some pics. Was gonna build a kit with it. Its not a bolt in for the 76, its more like a t4 BW s480. The t4 bolt pattern is a little diffrent.

Yea it's a t5. You can slot the turbo manifold flange and the turbo a little and should be good.

What no twins for a choice?
Dual s480?

The opening of turbine inlet is the sames size as a T4, just the bolt holes are about 1/8 wider on both sides.

You going to make any quick spool valves? A 475 with one of those would be fun.

It's an 88mm turbine and a 1.15 a/r I believe is the only size they have right now.

Just had to look it up ha ha. 88mm inducer and 77.5mm exducer.
I like looking and comparing the exducers against other turbos.
What's the price on these?
