Will this turbo header fit????
I know its hard to tell from just a picture, but any opinions would be appreciated. This is the turbo technology header from their Impala kit.

Looks like it would fit on the drivers side no problem, but it also looks like it would put the turbo too high and mostlikley hit the hood.

Looks like it would fit on the drivers side, but a big turbo (T4) will be close to the hood. I would actually be more concerned about the turbine housing and downpipe though. I don't think you will be able to fit the cross-over pipe and an adequately sized downpipe between the engine and the steering shaft. I know this is very tight with the brake booster and master cylinder right there, but the steering shaft location will make it next to impossible without serious modifications. This was an area I had trouble with in my JY twin turbo set-up on my 89. I actually used a 2.5" pipe and smashed it down to 1.5" To fit between the manifold and the steering shaft (I could get away with this because it was a twin set-up, so only half of the engine's exhaust went thru each downpipe). If you used this manifold, which is designed for a single turbo, you will need at least a three inch downpipe and it would be very tough to fit into this location, not to mention that you need to connect the crossover pipe in this area also.
Looks like a very nice header though.
I could e-mail pictures of my modified stock manifolds for anyone who would like to see them. This is simple to do and has worked well for me so far.

that makes me soo sad, considering the small #'s of those cars built in comparison to ours, that they would get a turbo header and we wouldnt 
flip the picture around, put the turbo more forward and lower, add a wastegate port and this would be magic (hello guido?
). or atleast more like this:
