I'm not sure if I'm allowed to say. Let me ask mike if I'm allowed to share that info yet since the kit isn't actually available yet

Looks like I need a tranny build then since I love going to the drag strip lol

Not unless you will be trapping faster than 125mph. That's where 4th finishes up on the 7AT. A valve body upgrade ought to be sufficient for a topping out 4th gear.

hmmm interesting. but still i usually hit higher than that on the highway sometimes and i dont want to blow a transmission in the process. idk if just a VB upgrade would allow me to do that.

In regards to the second half of your question, I personally feel like it's a really tough pill to swallow doing the transmission first and then doing the TT later as the performance gains from just a transmission build aren't exciting enough on their own to justify the cost. If it were me, I'd do the Twin Turbo, transmission cooler and tune to increase line pressure first, drive the car and enjoy it (within reason) while saving up for the transmission build.

Again, it's not truly necessary to build the transmission to have fun and enjoy the car. For example, I know that the transmission in my Subaru is made of glass and is ultimately a ticking time bomb...that didn't stop me from upgrading my turbo within reason and enjoying my car for what it is. I just take care of it and don't beat it like a drum...simple as that. I still track it occasionally and stomp on the go pedal when I feel like it, I just don't abuse it and change the fluid regularly. One other tidbit is that I do not take it to the drag strip because I know that all it takes is one bad launch to grenade that box into a trail of shrapnel. Know the limitations of your hardware and drive accordingly.

The bottom line is that if you are adamant about doubling your power and want to thrash the ever living $#!^ out of your car, then yeah, you ought to build the transmission to take the abuse.

Thanks for the response Mike. That does make a lot of sense.

I don't plan on thrashing my car any more than what you're doing in your subie until I have another car as a DD so if something happens to the Z I'm not transportation-less.

Are the upgrades that are done to the 7AT in conjunction with the TT build things that are again improved even more with the AT build, or is this a separate solution to the increased power?

Mike or Sam - Is there a way to tune the car so that when the car is in 6th or 7th the boost will be less? That might save a few transmissions that aren't built.

Know I am not Mike or Sam, but the Z's factory ECU doesn't control boost, that's controlled either by WG spring pressure, manual boost controller, or electronic boost controller. There are some high-end EBCs that can do gear / speed specific boost control, but I am not sure if any of those work on the Z or not.

You are right.

My HKS EVC can do that.

The HKS EVC 6 electronic boost controller can be programmed for per gear boost. That said, you can't run boost any lower than wastegate spring pressure. Most of our kits ship with 6psi springs, so that would be as low as you could go.

Also, I don't know if you knew this or not, but your right foot also functions as a manual boost controller that can change boost pressure on the fly.

I was born with a tragic birth defect on my right foot: PB distum pedis. also known as... Lead Foot.
