Im glad to see a single kit come out. I am assuming this would be cheaper since you are only using one turbo. Is this going to be a direct bolton? Any ETA on some numbers, or are you still in the planning stages. I am very excited about this turbo kit!

 

Doesn't mean it will be cheaper, just that it will keep costs down, better parts,

then again he did say to "We'll be prototyping this in an effort to keep costs down for you folks!"

 

With my limited knowledge of FI, I think a single turbo would be better for our cars. Correct me if I am wrong.

With bolt-ons for better breathing and enhanced performance, our bottom end and off-boost power will be fine lower in the rev range. With our 6 speed trannies and the fact that shifting doesn't put us below 4,000 rpms (or is it just me?) on throttle, we should never fall out of boost when we don't want to.

It just seems to me that we have enough torque to take care of ourselves until single turbo boost kicks in. Plus, I don't want boost in the low-low rev range for every day driving because I have a base model, so that means no traction control . Single turbo setups should be cheaper and take up less space. Seems like a winner to me! Please correct me if I am wrong on any of this or just chime in with your opinion!

 

3.5 liters of displacement would be nice behind a mitsu 24g compressor! (Not that they are using this, But the 24g would be my first choice) I pray for someone makes a single turbo kit! Less heat under the hood, less expensive, less pipeing. Single turbo is the way to go. Oh yeah! LESS LEAKY OIL LINES!! gotta love that. I am waiting!!!!

 

Ultimate Racing,
any update on how the kitis comming along,

 

Hey guys,

Our 350Z has already gone under the knife. Fabrication has begun, however, we're missing a great deal of parts that are being delayed because of the fires in Southern California.

I will keep everyone posted.

Thanks

Darryl

 

Whats your ET on the finish of the kit?

Bill

 

Heck guys, it's only been 15 days - they're gonna need a little time before even a preliminary ETA is available

 

Thank you, sir.

Hang in there guys. I assure you all, the wait will be worth it!

Darryl

 

I have one question, that might sound silly to some of you.
What is the benefit of putting a single turbo on a V shaped engine?
You have two sets of exhausts coming out of each side of the engine. How can you manage to extend the exhaust pipe to the turbine? Or is there going to be a turbo on just one side of the V?
That sounds like it is going to worsen the balance of the engine?

Can someone explain this?

 

I don't know maybe we should ask the Grand National guys!!! Just kidding. One good benifit about a single turbo for our cars would be that considering we build a good amount of torque at the bottom end we don't need anymore so the lag would fix that and give us power were we need it, up top. also with all 6 cylinders going to one turb we could use a bigger turbo.

 

oh by the way using one side would be very bad for our engine. all 6 cylinders will goto the turbo, not just on side.

 

I am thinking the exhaust manifold will have to be built this way... this is an HKS 'up-pipe' for a Subaru Impreza WRX. As you can see the subie exhaust ports are opposite of each other as well as the V configuration engines of our z's and g's. The 'header' or exhaust manifold will bolt onto this up-pipe which will reroute the gases to the turbo. Both ends of the up-pipe must be equal lengthed and also short for maximum performance gains (or so people say). Basically.. you'll have one long header system to a turbo... sounds kind of however the maxi guys are really content... wrx guys don't seem to have a problem with it...

although twin turbos sounds REALLY NICE... the most important concerns I would have are the wastegates, extra lines and the cladding of piping... just overall sophisticated. Gotta lose some to win some i see...

on a side note:
Log style exhaust manifolds have been utilized for quite some time now.. as in ActiveAutowerke's m3 kits and the performance gains have been very impressive... can anyone explain the pros and cons between each style of exhaust manifolds?

 

Um, that is the header/manifold, not the up-pipe. The up-pipe connects the 2 bolt flange at the collector to the turbo.

 

thanks guys. very complicated...

 

By the way do you have any plans to sell the single turbo kit in Japan?

 

Have you talk to Top Secret? I heard they have a single turbo kit running 460rwps in japan. That would be your best bet.

 

Yeah, Ive checked out Topsecret.
But it was more of a one-off rather than a turbo kit.
Right now Im waiting for Greddy twin turbo kit which is said to come out at any time.

 

Haji, US turbo kits wont fit on your car, and Japanese turbo kits wont fit on our car. This is because the steering rack on opposite sides. Both Greddy and PE had to redesign theirs to work on US cars. You should just have Top Secret construct you another one off kit.

 

jesus, i was totally forgetting bout that point...!
thanks for the reminder.
