Either that or add up what the cost of gas/hotels would be to get there and a plane ticket back x 2 of course... Which is cheaper?

Well for sake of argument and last off topic post lol shipping it would be a lot less since gas on avg for premium would be 3.85 a gallon and 3000 miles one way it adds up lol and plane tickets to Cali are like $800

Then just ship the damn thing! FProblem solved.

Sounds good I will ask again in 12 days time.

Also I'd like to thank mike at Gtm for the offer of a quote and quick response afterwards. Kudos for the great customer service to mike and all the guys at Gtm.

How much for the Tt kit

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

I know logically which one sounds better as a given, but say finances didn't permit both, you would opt for the tranny work prior to the TT work correct?

In the grand scheme of things, it would be ideal to do both the Twin Turbo and Transmission at the same time. Ultimately, it would save on transport costs and doing it all in one shot would allow you to truly enjoy the car from the get go.

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.

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.

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.
