I really didn't notice much if any lowend torque loss. The cold start is fine, but it just wont run well at all when its cold, it needs to be about 65C+ and it runs great!
You need a nicely matched single turbo for that. Pertty much the same setup I want to run in a few years when I get back from over seas. But I'm still figureing out what turbo I want to go with...
jeeez man, thats some fast *** revs there
im non seq too but no way does it hit 8k that fast, and in second too!!
i guess the half brid does help in this situation..anyway, get yourself on the dyno, maybe you dont need to rev that high..

Building a half bridge motor isn't rocket science. If you break it, you replace a couple parts, do some port work, and throw it back together.

A few forum members can vouch for it
I need my single turbo really bad, im trying not to drive the car that much and hard all the time.

Ya some one posted what twins looked like with a few runs on a half-bridge. They were totaly trashed. The pics looked as if they could have just fallen off the engine. I don't remember if they were posted here or on the other forum.
Half-bridge ports are designed to run 9k+ rpms. A properly matched sigle that pushes near full boost(15-17psi) around 4.5k on a street port would probably work really well on the street. This is because the larger overlap forces the turbo to spool faster. So with the larger port the turbo could come on full by 3.5k-3.75k.
Man, I can't wait to build mine...
