First idling of the 1/2 bridge

http://www.youtube.com/watch?v=5ozpit8NtGE

Don't rag on the few missing bits here and there

It is LOUD. If you want attention (of both the right and wrong kind) 1/2 bridge your car hehe

Still lots of tuning to do with the Haltech, its misfiring very strangely, but its running now so some driving/tuning will help immensely.

Fuel delivery issues and that vid was snapped before I zero'd the timing and started dialing that in. You can't hear it missing?

The front mount is an FD Godspeed one I modifided. Didn't want to ditch the rebar and wanted short piping so I routed as you see. The core is about 13" tall by 22ish wide 3" thick. Should be good for my power goals of 400ish

The turbo on there is a shitty ebay job I did some trial and error with before. I'm using it to break in the engine then I'm switching to my T04-R. The one on the car is a 60-1 with a 1.15 A/R ...............the R has a 1.00 divided.

I idle at 1400 rpms because my exhaust ports ARE HUGE. If I set the idle any lower it wants to sputter and die....

Wow, that sounds really good. Nice and deep.

Not that high whine pitch that sounds like a broken lawnmower.

Way to go man!
