Killer turbo kit. Wish I had the means to bring it to my car

just incase u are serious....no it won't. if u use a muffler like the magnaflow and exhaust pipe out the back ur car will accually be pretty quiet. u'll hear the sound of a v-8 somewhat but u'll also hear the turbo spinnin....u'll like the sound it'll make.

CAT3- As far as using stock manifolds, you could build a system that way (that was the very first version of CAS's twins), but turbo placement is less than optimal and plumbing/drainback becomes a problem. With the way mine is set up, the turbos have to be exactly where they are. I spent an entire weekend making adjustable brackets and playing around with turbo placement until everything was in the best position.
obZidian- Since I am using Precisions 5 bolt exhaust housings, the only a/r's available (that I'm aware of) is .48 and .63. Though I won't know for sure until I tested on the dyno, I would assume that anything larger than 370ci would have excessive backpressure with this system even with the .63 housing. IMO 400+ci engines would be better off with twin T4's or a single T6, and I don't think I could fit twin T4's without notching the frame and heater box on the passenger side.

A GT35R is available with 3 exhaust housing A/R's. .63, .82 and 1.06

Well, I believe you could fit larger turbos if the heater box was removed and the frame was notched (the part that interferes houses the evaporator core not the heater core), but if you're removing that you're defeating the purpose of this system and would be better off mounting twins up high as we did on Andys car.

Well the update is that the fixtures are finished for the headers and the y-pipe, still need to make the fixtures for the induction piping.
Those should be finished by the time we recieve the next batch of materials, enough to initially make another 5 systems.
As far as the exhaust housings, I built the system with Precision housings, which to my knowledge are only offered in .48 and .63.
The link to ATP's turbochargers which HPCubed posted shows they offer the GT35R's with higher a/r's, but I'm not sure if those exhaust housings external dimensions are identical to Precisions housings (which they would need to be in order to fit).
My comment as to notching the frame and removing the heater box was in reference to fitting T4 turbine housings in that same location.

We finished all the jigs except for 2 of the pressure side induction pipes on saturday.
I have an order in with SPD for materials which we will recieve in 10-14 days (per SPD). Enough to initally build 5 more systems.
We are direct with Tial, and last time I spoke with Precision they had GT35R's and Intercoolers on the shelf.
So, things are moving along well. Not at light speed, but we're making progress.
