Which would be better to run? I would assume external?

External is always better if the budget allows it.

since these manifolds are goinna have the port for the ext wg anyway, would an option be to get the down pipes for the kit that have the int wg so it will bolt to stock exhaust and then install the ext wg and have them dump to atmosphere? i prefer the ext over the int, but i dont need the 3" downpipes

"Needed" is a bit subjective. For me, I focused on significant upgrades to the overall cooling system, a good EBCS, and gauges to keep my eye on things. Did not replace the clutch yet because it is not worn out yet. Only have 4700 miles on the car. I drove my 490 WHP STI on stock clutch for years, though it did start slipping at the end. When my Z starts slipping, I will address that.

OK I have an issue. I come here several times a day and stare at this kit. Is that normal? I'm addicted. Like my needs are never met. I really need to work in a performance shop.

Same here. We should have a weekly meet like alcoholics anonymous! :bowrofl:

If you dont have to relieve yourself after that than you are still normal :tup:

i JUST got the car on Friday. and im seriously considering this...

^ Another Atlanta guy. Woot

I'm craving it too. Riding around in my buddies vette with 438hp..... At the crank! Can't wait for 500whp

You guys are going to love the gtm kit.. I always look forward to when I have a chance to take a spin in my ride.... Now I need a new clutch and a boost controller...

Now that I think about it, this many pre-orders will be great for guys that wanna boost in a few years. Think about all the cars we can monitor for reliabilty and how many miles, what boost level and hp, etc.

I feel like this is gonna open up the 370z world a bit more. One step at a time.

I am hoping by the end of the year my inbox goes crazies or this thread increase a lot. http://www.the370z.com/forced-induct...ed-builds.html
Trying to keep track of as many as I can and with this many people on the list we can get a nice log going.

anyone know how the ewg's are gonna be ran? i havent read thru every page, so if it's been mentioned sry in advance. but are these gonna be routed back into the exhaust or open dumps? if open dumps, then hellll yea. i love the ease of internal wg's, but im slightly worried about boost creep with my 2.5" test pipes

Recirculated external wastegtes, is that an option?
