Single turbo about 400hp at the wheels about $5,000.00
Twin turbo about 400hp at the wheels about $7,500.00
1. which option would you choose,
2. would you buy it?
thanks for your input

2. Not for 3 years/36k miles unless my warranty is preserved, something I think will only happen with Nismo.
In short, sorry James but, probably not in my near future.

SX7r (Thomas in Dallas) runs 12.8 on his VQ30DE (4th gen Max) with a FMIC and single turbo, the compression is slightly lower than the Z, but I would think the internals are slightly improved.... So, I would guess a max of 12, and that may be pushing it for the long term. 10-11 would probably be about right.

There would have to be some significant advantages to the TT setup. I had already thought that I'd limit an FI solution to about 5k, and I'm reluctant to do even that if I'm voiding my warranty with no other warranty to put in its place.
I'd vote option 1.

We are gathering interest at this moment,
The car is being taken apart for evaluations next week,
we car currently planing to use a T3/T4 turbo, I like to use the ball bearing version as it does spool up considerable quicker.
The VQ35 from inside sources at Nissan should take 8 psi with the stock internals, i will be using my 350Z for durablility testing, from my sources at Nissan , the tranny (6 speed) is comfortable on taking 400hp / 400 pund of torque.
I will keep you posted on the project.
As for the Twin TUrbo set up by the other company, from a marketing perspective I agree the Twin Turbo sounds awesome, but in terms of marketbility (due to the high cost) we don't know if the public will accept the high cost, that remains to be determined.
I have had good luck on our MR2 spyder turbo thus far, I like the 350Z very much , and i think it has great potential.
Regarding the fake HKS interfooler question, yes it is my car, yes it is a REAL intercooler, no it is not functioning, we fab it to see if they is room for the intercooler and piping, the people form Nissan really like it and ask us to leave it in for the SEMA show and LA auto show, it will be turbo soon, (hopefully in a month)

option 1 for me.
I currently have a T3/T4 on my old (and recently undriven) 280Z. The ball bearing mod should help lag which is acceptable on the 280. However, if I were doing it again I would consider an air to liquid to air intercooler system so that the piping length could be reduced (this would also reduce lag). Since I in don't spend time on the track so I would not be in the turbo for extended times the air to liquid to air intercooler would work. (I would also like to try to cool down the liquid reservoir to a little extra).

What are you going to pull over at every stop light to put more ice in when summer comes around? Air to Air setup is best for street use. Water to Air is the best setup for drag racing. It you have a properly tuned kit the lag will be very short.
thanks,

------------------------
Guilty as charged, DSMer here ...my fourth vehicle is a 95 talon. Do you mean you think a 20g would spool at a lower rpm on the VQ35?
------------------------
Based on our gearing, compression ratio, and engine size.. I think we can make 8 lbs at 2700s rpm range.
But I like the T3/T4 since there are so many different variations out there (good for prototypes). The 20G was easy for us since we don't have to change the exhaust manifold on DSM.
Good luck Axis!

Why isn't the Single turbo pulling more horses out? How big is it? Obviously small if it can't get better numbers! My brother had twins on his supra with 320 hp and when we put the T-66 single it took it to 627 RWHP with an upgraded fuel system!

you are comparing a car designed for low compression and turbos to the Z with high compression and internals geared for NA use.
IF the internals would take it and you lowed the compression ratio (ie...more boost could be dialed in) then we'd see the monster numbers like the Supra puts up. Not to mention those cars were way over engineered...perfect for enthusiasts though.
Several 500+ hp 300zx's running around Dallas as well as monster Supras, but they were all designed for forced induction. As we see more parts for the Z.....we;ll start seeing these numbers climb. Personally I think 360ish to the wheels will satisfy me. I would live with that.

OH YEAH.....Axis, I have to vote single turbo as the Z has enough torque down low to be sufficient with only the one. A sequential setup with a smaller turbo would only make a good launch and 60' time almost unattainable. You'd spin all over the place. Full boost at 3-3500 would be perfect.....IMHO.
Good luck and please keep us updated.

If I were to go the turbo route, then I would opt for the simplest solution. Simple = less headaches. 300ZX twin turbo = complicated = worries = headaches = $$$

Option 1.
Twin turbos would be "nice" there's really not much reason for them other than a less complicated exhaust manifold setup if the single turbo is properly sized.
Honestly, I think the car has plenty of torque low-end so I could care less about a little turbo lag. Nobodys going to be running obscene levels of boost anyway on the stock internals so such a kit should have an appropriately sized turbo.
At the point where someone is building up their engine with low compression pistons and beefy rods they can go for a much bigger turbo and simply bolt it on and adjust mapping.
Too bad no one at Nissan is smart enough to give us an engine option for "stregthened internals" straight from the factory. I'd have ponied up $3k for that without hesitation... Ahhh one day they will get enlightened.

I can generate more power at 10 PSI with one turbo than another at 18 PSi on the same exact motor. ....................... What you want is a properly matched turbo to your engine size and your power goals.

As for the Axis set up (if it is still under development), I think I would go with option one.
Same output... less headache... and more within my budget.
The only reasons I would go TT would be if it produces more power and because it looks and sounds cooler to say you have a Twin Turbo.
Regardless, I would not buy either of these set ups unless the target price includes install and comes with some sort of warranty. Without these elements, I'll wait on GReddy or Nismo to roll something out.

I had a small (SP63) Single turbo on my Supra. It spooled nearly as fast as my stock twins but produced significantly more power. On low boost it would hit over 500RWHP and 600RWHP on high boost. I would not be worried about the lag of a single turbo.
A single will be less expensive, weigh less, produce the same amount of power and will fit better in the engine bay. Sounds like a simple solution to me.
I would be more concerned about traction isssues with this car. My car with CAI and grounding kit breaks loose in shiftronic mode at roughly 287HP. I can only imagine what would happen with 400HP. I would need to purchase slicks just for my commute to work
