What about the gt35, (m24, a/r.70, 1.06 hotside that came off the car that I already have? It spooled slow IMO, but maybe that was setup, injector, the shitty leaking chinese manifold, leaking vaccuum lines, poor tune problems, or porting issues, who knows. Thoughts?

Divided T4 exhaust housing is available for GT35R (GT3582R), so you should be able to use that with off the shelf rotary manifolds on the GT3576R.

Only problem is the GT3576R costs the same as the EFR 7670, then you have to buy the right exhaust housing and of course it still doesn't spool as well.

However : If it costs the same as an EFR , Garrett needs to seriously rethink their pricing if they don't want to die a slow painful death.

Dies off and runs out steam as bad or worse than a BW 7670?

May not be able to do that with the IWG. I used the light springs for run-in purposes but they work well and are great in the wet so they stay. EBC has no prob with 18psi. (maybe more? car is tuned to 18)
Went with ewg for packaging concerns more than anything else (tight engine bay/ existing twin gate mani) but glad i did.

EDIT, but if you need new manifold anyway and already have water inj, it would be mad not to consider turblown iwg kit. Those cast manifolds are sexy.

Full boost not far off 3k.
