Yeah, but with the larger wastegate that creep should be prevented. The average ported stock wastegate is like 20mm or soemthing... pretty small. HKS sells some with 45mm diameters or somethnig? Thats a huge difference.

I was referring to stock turbo.
With an upgraded, you'd use it to help the turbo spool, which is fine.
The main problem I was referring to is the change in boost. Boost builds up... its neither on nor off. Thus, nitrous use at 3000 rpm with a T78 would be running extremely lean, since the turbo boost pressure would be low, and thus the tuned fuel pressure would also be low.
The only real way to tune nitrous, unless you have an aftermarket turbo and are already at full boost, or don't use the nitrous under boost, is to run your own, non-referenced FPR and pump.
Can anyone guess my next set-up?
BTW, the kits will include a system for this.

The Problem is being able to run those damn vacuum passages between the spray bars.

I figured I'd go ahead and bring this one back to life. Any updates on the NOS kit? I thought I had heard some rumors about Scathcart leaving the RX scene, so I was wondering if the kit has been dropped.
