I remember seeing this on AZ, very nice work. Any idea if the owner is a drag racer at all, I'd love to see what this could lay down?

[mbgt72]

impressive, can't wait to see some serious info be posted up on it and see that thing hauling. I'd always wondered about a single turbo conversion for the B5's. I know size in a constraint, but man you could really go through the roof on the upper end with a big spooling turbo!

Things to come:

STANDALONE ENGINE MANAGMENT

Of all the thanks to Unitronic Chipped and support they give you, why are you guys switching this car to stand-alone engine management?

Second, if there weren't pictures posted then you could go ahead and delete it at the rate it's getting updated.

Quintin Fail. Why doesn't that surprise me?

[drew]

can you say turbo lag...

[JohnnyAlQaeda]

can you say turbo lag...

tru dat. i really dont understand the point of coverting to one huge fucking turbo when you could run two moderately sized and not have to wait till 6k rpm for the thing to fucking spool. granted thats probably an exagerration but you get the point.

[beemercer]

I don't know, the 4094 isn't all that huge.. seems about the right size for a 2.7L that can build some revs (built head).

Hell, the 4.2 should do well with a single GTX4508R anywhere between 10psi and 20psi.


It ends up coming down to cost, you could get two $2k+ small frame BW EFR's or GTX's or any other high-spec billet wheel turbo... or you can get one $2.5k large frame high spec turbo and then build a twin scroll manifold for it.


I personally would prefer a single large frame turbo with a twin scroll manifold, it's too bad the B6 engine bays would limit that with a 4.2... though the C5 may be better off

wow i haven't been on this site in forever. To answer this question...Time. Mike Z just doesnt have the time to tune all this fancy one-off cars we make so with Standalone you can at least call in a schedule a tuner like Kevin Black, Chris Miller, or maybe even Jeff Atwood (to name few).
