I know a little from MC racing. But that wasn't my question. If I'm reading this stuff right the bigger difference between the V2/V3 is quality and that external resevoir. But it looks like you need to choose adjustability to get it. I don't disagree with you about not needing adjustability. I want to know if I'm giving up quality along with it?

Jim,

If I were considering dropping $8k plus installation cost I would consider shipping the car to Fast Intentions or GTM.

That'll be my set up one of these days.

Meulen

Are those really a "true" coil over though? Don't they use the stock perch?

Correct. Not a true coil over, however for what I intend to use my Z for (pleasure with maybe some track time), it'll be plenty.

Meulen

GTK! I guess that would give me the option of doing the springs now and going with the Koni's later as well if I wanted.

Oh....and Sean. I'm reading more about the V3/V2 comparison. I'm still not sure if the V2 is a lower quality and less technology option of the V3. Correct me if I'm wrong on that? But I did read the adjustability of the V3 is only for low speed driving. Meaning, high speed track valving is pre-set still. You wouldn't have to mess with it on the track, just have the ability to make adjustments for a more comfortable street ride.

KW V2 vs V3 is the same technology, just different features.

It comes down to whether you want:
- V2 rebound adjustability or
- V3 rebound and dampening adjustability (you're correct on just the low-speed part)

P.S. KW's own site said: The “reservoir” on a V3 is not the same as a “reservoir” on one of KW’s 3-way race shocks. There is no adjustment, or performance advantage of the “reservoir” on a V3.

I thought V3 use stock perch as well

I think they come with a new perches...or am I understanding this wrong?

Well.....looks like there isn't a KW V2 for the 370. So only choice I got with KW is V1/V3

well....I guess it's just my opinion, but.....

If I were dropping that kind of cash and going twin turbo it would be for one of two reasons
1. I'm going for a major cool factor of the twin turbo or...
2. I'm planning on breaking open the block and building 1000+ HP monster

Honestly, even with #2 I'd have second thoughts. One big turbo should more than do the job to deliver enough PSI to get over 1000hp. If I was planning on playing it safe around 500hp no way would I spring for the twin setup. It's just a waste of money.

The guy I recommended you talk to on facebook is a young guy, long time Z fan. He's just building a business so he can't afford to specialize in Z's or tuning, or anything else. He's an all around body/performance/mechanic shop. Quite honestly, I don't think the demand is there in our area to support a specialized shop well. He know's his stuff though. I trust him because I talk to him all the time. We are constantly in each others garages lending a hand on each others projects. I'm confident he knows his turbo's because I've seen and driven his custom made system on his Lexus. He literally bought all the components, bent the pipes and built his own kit. My only point here is, there are guys here that can do the job you want. You may have to open your mindset away from the hype of twin turbo systems or the popular shops and find a guy in an unconventional place to get it done. Or bite the bullet and ship it out for the cool factor and piece of mind of more reputable place and build. Either way your car will be sick! just something to think about!

Single turbo is really only up to 500 or 550 whp. After that, the turbo lag will be bad. Sure you can build a single turbo 1000 whp monster, but it will only be useable at the track and there will be very little power in a daily situation. Twins help resolve that with quicker spooling/smaller turbos while maintaining power levels. A popular mod for TT supra was to convert them to single big turbos. This made huge power at the top of the range by sacrificing low rev range power. Great for 1/4 mile and highway racings, not so great elsewhere.

Here's my logic:
If you want cost effective turbo kit and plan to be around 450-525 whp, get a single turbo.
If you want room to build the motor eventually/ get 600+ whp, then plan on investing in a decent twin setup.
