Here's some nice pictures of the same manifold. I had it and sold it to a member on here. If I could go back i'd definately go with that instead of this junk HKS.

looks like the pics are as useless as the OPers link. Here let me show some pics I took.

 

Damn I should have gotten this thing heat coated and just used it with a 60-1 trim.

 

It definatly adds some engine bling. Is that upper or lower mount? also looks like they only do that for the 1.8. WG also quite far away from collector.

 

Upper, and the WG is on the 4th cylinder.. which I'm not sure is a good thing considering our 4th cylinders heating issues.

 

that thing is a POS

 

The WG is meant to be as near to the collector as possible otherwise it can create boost creep issues apparently.
