No, althought they did ask.

You got to read buddy, it says Edmonton right on the dyno chart

On par with the TT kits. A ST will make more power/psi up top though, as it is known to be more efficient. This turbo will be great for the stock block, and I am confident that it is capable of making 600whp with a larger turbine housing. It is on par with twin GT2860 turbos as far as air flow goes.

The other turbo will be the 6766, and that turbo will move 30% more air, making it a great option for those that do plan on building the block down the road. It wil be a direct bolt on to the kit, and nothing will have to be changed...it is a direct swap. This is a rather quick upgrade from Stage I to Stage II.

They flew into Edmonton for a group tune. They come just about every year

Wow, nice numbers! Lucky manual guys, haha. No love for autos.

The Edmonton Z Car Club brings them up annually to tune all the local guys cars.

Here's an STS system getting checked out by Seb

sent from my SAMSUNG- SINGLE TURBO SGH-1717

This does look pretty close to a TT, as expected it appears to spool a tad slower than the gt28 .64 twins from what I've seen and power/torque looks very very similar as well. This is a very strong competitor to the GTM twin kits, and the simple install makes this VERY appealing. Though GTM's new mitsu kits are looking really nice as well to reduce cost/install.

I mentioned in a previous post, but if this were available to purchase when I was looking I likely would have gone this route simply due to the incredibly simple install.

Yes, the power deliver is on par, as expected. The twin scroll turbines are very efficient, and clearly do a great job.

With this Precision 62mm turbo that comes with the Stage I kit, 600whp should be a reasonable estimate of maximum power with a larger turbine housing. With the kit already including large injectors, larger fuel pump, and complete oil cooler kit your savings get in to triple digits.

On top of that, there is still the install portion of the kit, which is half the price when comparing the kits directly if you do choose to get a shop to install this. Or even better take a weekend and install it yourself, since it is very easy to do.

Nice numbers bp and excellent work with your kit. Glad to see different options coming out for the Z/G.

BTW, what were the numbers on the STS?

440 and 370 at 8 psi curve is not near as smooth tho.

So excited!!! I'm personally gonna have to wait a bit longer a minimum of atleast 2 years. Oil prices dropped and need to make sure I have enough savings in the bank incase IT hits the fan again.

For others like myself who completely missed the results thread:

With all you guys that are on the "list", how may are looking at reciculating the wastegates and how many would like open dump tubes?

Remember open dump tubes = very loud

Open dump tubes will also be cheaper.

recirc

I may get flammed for this comment but....

we don't drive turbo civics, do the right thing and recirc lol

open all the way for me

bring on the noise :ughdance:

these cars need a little more sound, to quiet for me, and the car should still be quiet when driving out of boost.

Open dump will only be loud if driving hard correct?

Just to get an idea on volume, is it a lot louder than running NA with HFC and CBE at WOT and high RPM?

Running open waste gates is as loud as open headers would be. And, yes it will only be that loud when you are on the boost.

Open waste gates are cool for about a month. Then it gets real tiring. Just recirc them and get a non resonated exhaust. I LOVE the refined sound that comes with recirculated waste gates.

Rep'd :tup:

I would probably get recirc...

Thank you sir!

Here are a few videos that I have taken that should show what I mean:

Open waste gates and Berk exhaust:


Open down pipes - No exhaust


Recirculated waste gates and Fast Intentions 3" Non resonated Exhaust

Thanks for the vids. The last one was the best. Recirc for me.

I would suggest re-circulate because as mentioned, loud will get old.

The donor car had test pipes, and the 2.5" dual F.I exhaust when it came in. When it left with the turbo kit on it was quieter than when N/A. I would say at idle it would be comparable to stock because the twin scroll does act like a big muffler.

At WOT it is just the right tone IMO, but we all have different tastes. I like the stock look and sound, because I favor the sleeper idea. On the other hand there is the complete opposite side of the spectrum where a customer wants it as loud as possible.

Is there any other benefit to recirc besides just sound? does it help with spool or anything by keeping the air? if that is even correct on how it works lol

Open dumps will help with performance a bit in theory since the extra exhaust gas does not need to go through to the tail pipe. Less exhaust downstream from turbo means less pressure/resistance.

The three vids aren't a great comparison, but they are indicative. The 'quietest' exhaust has the camera 24" from the taiilpipe! LOL!

I've found VERY little performance loss with recirculation. In doing so you aren't looking over your shoulder, or annoying everyone, each time you want to step beyond half throttle.

I even went with recirculating the BOV. Quiet and stealthy across the board. YMMV.

Let the acceleration and exhaust note announce your authority, not from a dump. :D

Good builds here. Carry on.

Coop

I dyno'd before and after recirculating the WGs. Lost 8hp at the very top. Not noticeable and a very fair trade off. Loud does get old.

Having heard the BP on the dyno at WOT, I am very impressed with the even tone of the exhaust and also the overall volume/sound. Not at all 'boi-racr', more like controlled thunder... recircs are the key to a classy and powerful installation IMHO. James's car is a very stealthy turbo kit. Almost like it was a factory option....

recirc

For an 8hp loss, I'd do the recirc.

+1 recirc

I like noise.... but I want stealth...

Maybe a really loud BOV will tame my noise urge if I go recirc? or is it just because I miss my sti... that I even want a loud wooooosh:/

What to do, what to do.... recirc or no recirc?

Thanks for the feedback, sounds like this will be a recirc w/g kit.

Perhaps the select few that choose to go with open dumps will still get the down pipe with the recirc inlet, it will just be capped off. That way if it is too loud, or if if they get sick of it the recirc section can be sent out down the road and hoked up to the wastegates, then back to the capped port.


The Tial BOV's (that I use) are very quiet. If you want loud BOV noise, HKS is the way to go. However, these are a real PITA to install compared to the Tial. The snap ring can be a nightmare, and it holds the HKS BOV in place. If one wishes to use othe BOV's it is not a problem at all.

Any option to powdercoat the ic black for stealth appearence?

Also, any idea if the downpipe in this kit will mate to Nismo rear section?

PC can be done if requested.

I do not think the down pipe will bolt up to the Nismo exhaust.

Maybe a Nismo S-tune exhaust? ...since that one uses a Ypipe
But an OEM nismo (H pipe) won't for sure.

The downpipe in this kit will replace the h-pipe or the y-pipe for non nismo z's.

Downpipe would mate to the oem piping containing the resonators, then to the axleback.

Right, but the Base/Touring/Nismo Stune piping is a single pipe (after the Y pipe).
http://t1.gstatic.com/images?q=tbn:A...NCKrEWTz5tRDTQ

The OEM nismo is a dual piping configuration with two flanges.
http://www.the370z.com/members/equin...ck-exhaust.jpg
This is why I think Sasha says it will not fit.

Thanks for clarification with the images.

The nismo flange does look to be similar to the FI exhaust pictured in the build thread. Any way to confirm fitment?

Just from looking at the pics and remembering the FI exhaust, the bolts will not line up. It looks like the OEM Nismo has 4 bolts in a flat line. The FI used angled flanges on both sides.
https://specialtyz.com/shop/media/ca.../fi_z344_1.jpg

That, along with the pipe lengths (not sure if the FI front pipes are shorter/longer than the stock Nismo H pipe) would probably make this a no-go for a bolt up affair. Might be an easy exhaust/fab shop fix though.

I don't want to speak for Sasha though. I'll let him confirm
