Pardon me for asking, but why did you choose to go internally wastegated on this build? The ATP manifold is going to need a block off plate (which would be a great spot for an EGT and/or backpressure probe if you were so inclined).
I figured I'd start with this setup first. I prefer internal gates just from a simplicity perspective, plus having an external wastegate sitting on top of the exhaust manifold is a blaring red light should I get hassled by the fuzz (regardless of the car being exempt). Not to mention having to plumb it in to the DP ect.
IF I can fit it, you hit the nail on the head. I'll use the block off plate and put my EGT probe there. If I need more firewall clearance off the back of the turbo then I'll go external.
I'll know once the motor is in the car though, I'm pretty sure I can stick with internal. You're right, much better design. I had the traditional T3 housing on the T5R and even with the "ultimate internal gate" from ATP, I had 18psi from 4500 rpm on if I wanted it or not Hoping this one flows a bit better.
Oh and it's still between a GTX3067R and GTX3071R. I keep thinking the 67 but then I wuss out and think I'll want a bit more power from the 71. The GTX3067R sure sounds good though, good power with a wider power band. Honestly, if I can do 400whp (450 on e85) with a big power band I'm a happy camper. I sure loved the GT3071R on the t5r.
