I guess I should add that I'm asking this to decide if the speed inc setup would work out on my motor. Those two turbos were the options I have to choose from. I'd love a high and up front setup but prefer to do the install myself.

I'm trying to find a foundry that can duplicate the manifolds in cast iron in low quantities.
The other option would be to integrate slip/expansion joints into the manifolds, but I couldn't be 100% certain of reliability until they were actually put into service and tested.

How is the intercooler setup? Are you merging into both turbos into one outlet or one on each side and the outlet on top.
Very nice work...

Also the ETT 70 wheel alone flows 94.XX lbs/min.

I am hopping Jim gets these manifolds done with in a reasonable amount of time as I would really like to drive the car more without hesitation. Love the kit though.

thanks Chris.
thanks Chris.
, but you can read the numbers . Yes it is a bad turbo 
As for spool times it will be close. The wheel is a touch smaller, but the shaft in these things is larger and much tougher. So its a toss up.
