I wanted to know if anyone has a h22 with this rare ac compatible turbo manifold. Anybody making big power with them? They look like this:

 

I have one on my Ls, not an H22 though.

 

I have one, but my rig isn't finished yet (i.e. no numbers) however the shop that is doing my tuning used the same mani on another customers car a few years ago and made 500+ using greddy emanage ultimate and a SC61

 

I had one for a while, made around 500 WHP with an SC61 on a B20VTEC setup.

 

^ did the manifold look similar to that? Did you have any pump gas numbers? I herd from someone that these manifolds crack... anyone have this problem? Thanks

 

I ran the B-series version of that manifold for 3 years. Never cracked once on me. I made 400whp at 16lbs with a .63 Trim T3/T4. I used it so I could still run AC and PS. Sold it to a buddy and he's been using for months now.
