Pick up a Tens machine and ice. It helps my back big time!

This gives you efficiency of a single turbo (more efficient than twin), with the benefits of a twin turbo, where the exhaust pulses between the banks are seperated. With the twin scroll the two banks are seperated untill the exhaust gases reach the down pipe. To take it one step further, the OEM and aftermarket headers have equal length primaries, and this creates the desired scavenging effect, because each combution pulse is seperated from the next. Something a log style manifold simply can't do, due to the design and space constrictions.

The twin scroll will also outspool an open inlet turbine housing every time. This gives it a great advantage over the top mount open housing turbo kits as well.

The only way to avoid pulse interferance (increase efficiency) with a twin turbo is to build a tubular manifold where you have equal length primaries feeding the turbo. Here is a perfect example...R35 kits are now being build with tubular manifold, going away from the log style in order to reach the power levels not seen before:

http://www.extremeturbosystems.com/i...it-2-01-01.jpg

Greddy has also switched from the cast/log manifold and gone to tubular...for the same reason.

So that is one of the big advantages...efficieny.

Price is the other big factor. For starters you will save about $500 with the twin scroll single kit that is capable of producing the same power as a Stage II twin turbo kit. On top of that the twin scroll single kit comes with a complete oil cooler kit ($400 retail) value, larger fuel pump 340lph (vs 255) larger injectors 750cc (vs 600cc) as well as an oil pan spacer ($100) to increase the oil volume by 1qt. So that alone will add up to another $1,000 or so. Some nice clutch/flywheel money.

Simplicity is another thing to consider. No need to pull the engine, get a new washer fulid reserovoir, and removal of many OEM components is minimal. Car can be returned back to stock in a weekend, without ever knowing there was a turbo kit installed. Because of the "bolt on" simpicity the install cost is much less, $1,200 on the single kit, and about $2,500-$3,000 with any twin kit mainly due to the need for engine removal.

For results, you can go the the first post on the first page. There is a dyno sheet posted there.

Thank you!

This is exactly what I was looking for. I've seen some of the other Single turbo kits, and was just curious as to the differences between yours/theirs/TT, and this explains a lot. Especially in terms of what I'm "hoping" to achieve when I go FI.

I'm guessing with the Single turbo, it spools up much quicker, does that have any effect on initial response with wheel slip or anything?

Can't wait to see Install Threads/Videos/Dynos/Strip runs and drive by's.

I will read back through the development of this kit, you've really got me intrigued.

Now you were talking about clutch/flywheel upgrades for the 6MT, of course. For the 7AT, are you looking at requiring/will be needing upgrades there as well? I know GTM has AT upgrades, but as with anything else with the GTM branding, it's going to be insanely expensive (but worth it). Are you expecting the 7AT guys to have to upgrade bits with this kit as well?

omg. I just spent 2 hours reading this entire 89 page thread. I'm even more <3 for this kit now. An amazing product, and a strong dedication to precision and meticulous craftsmanship and customer service. You're giving Tony from F.I. a run for his money on best customer service seen here

After looking through it I only had 1 real question/observation:

The 2 cars that had posted pics of installs both had the Stock sway bars. Has there been anyone with aftermarket sway bars looking to install this kit (preferably Whiteline since that's what I have)? Only reason I ask is for clearance between the sways/oil fittings/lines/etc.?

And lastly, can someone go kick down the door of that guy who said he'd drop off his 7AT with you and steal borrow his keys/car so you can get under it and see if it is impossible to rig up a kit for the 7AT...

Perhaps your next batch of 6 should be for 7AT drivers...

Not only that. Your kit comes with down pipes with Wastegates.. While GTM doesn't even comes with normal test pipes

.. this alone is $1200 value

Its funny how GTM advertise their stage 2 kit for "600" WHP when their kit runs out of fuel at 500 WHP

The 3rd reason why this kit is better because this is a true full kit and true full bolts on! and here is why
This kit comes with Oil pan spacer for turbo lines, while gtm you either have to drill your stock pan or purchase a spacer.

This kit comes with Oil cooler, GTM kit doesn't come with that so you cant go to track with GTM kit otherwise say hello to overheat and goodbye to the engine.

This kit comes with large injectors and fuel pump to be able to make "600" hp without running out of fuel. While GTM comes with 600 injectors and 255 that are known to max out at 500 WHP.

And there are many other reasons but last and not least, when Boost performance gives you a lead time for kit. it will come in time or even before that! but with GTM? I don't even wanna talk about it

Don't get me wrong, I have GTM TT kit for my self but im just saying the true facts

Way to go Boosted Performance!

I'll let you know how it fits. I have Whitelines.

The aftermarket sway bars have the same shape as OEM, and are only a bit larger diameter. This should not be a problem at all. The oil fittings are also way up there with the OEM oil pressure sensor, so there is no chance of contact.

Now that you now know that this kit does not work with the 7AT. I will try to do something about this in the spring/summer next year. If I can find the donor car, by all means I would do my best to make this happen. The manifold will have to be different for sure, and I am not sure if I can keep the twin scroll for it. The OEM 7AT oil pan is so large, and takes up a lot of valuable space under the car. I have been known to perform miracles though....so you never know.

You are right, these are the things that a lot of people miss when looking at/purchasing these kits.

IMO, if it is needed, why not make it a part of the kit. It saves the customer the run around and frustration. When I say this kit will support 650whp in the Stage I form (that is over 700hp as advetised by others, since they advetise flywheel) out of the box, I mean that because I have customers that have done it. No further upgrades to the kit are needed, of course other than the turbine to support the flow. That however is only about $250, and takes 30 minutes to swap (5min if the turbo is out).

I think it is also important to mention service if something does go wrong. I have a local friend who blew one of his turbos on the APS TT kit on his G35. The bill on that: $4,500. The shop pulled the engine out to remove the turbo, so that set him back $3,000 alone. He ened up getting both turbos rebuilt...and the kit only had 11K miles on it. The turbo that comes with the BP kit cost about $450 to rebuild (by the manufacturer, Precision turbo), and I can't see a shop charging more than 2.5 hours labor for removal install.

Perhaps it would be easier to make a different oil pan for the auto trans? Or relocate most of it to the side or elsewhere? Integrate it to an oil cooler to give you the same volume of oil with a flatter trans oil pan? You'd need to know how deep in the oil pan parts of the valve body go. Never pulled off the pan on those trans and can't seem to find a decent photo of the trans so don't know if its feasible or not, just throwing it out there but I'm sure you've already thought about it.

It's not just the oil pan, it is the entire castin of the transmission, that is large:

VS manual:

You can see that the turbine housing with these turbos is rather large..this is what allows this kit to make the claimed power.

It would be difficult to do, but I can always try.

What about a smaller turbo setup for the auto guys? Or twin turbo kit with double twin scrolls.

Yeah, I noticed that photo not too long after posting. Guess it's not gonna be that easy. It's a bummer for the AT guys that those auto trans really do take all the space available.

I had thought about a smaller turbo, but can't really do anything without a car at hand.

Double twin croll...that would defeat the purpose and simplicity of the systems. You also need at least 4 cylinders for that to work...so a V8 with an alternating bank combustions cycle.

If a local opportunity comes up for me to look at this option, I will. As it sits now, I can't keep up with the demand of the 3 rurbo kit options I offer for the VQ's. I am going to start building 4 kits for the 350z guys right away. After that it looks like I can easly build another 6 370z kits, and those would be gone instantly.

Nut_N_Much · 12-23-2012, 05:26 PM

My god man, I just read through each page of your thread and it was the best read I have had in a long time. It also pisses me off that I didn't have the patience to wait and get your kit. I haven't even installed my Stillen yet and I want to sell it already.

Great build, you have some mad skills. Can't wait to see the 7AT thread come to light.

This may sound extreme/crazy/ridiculous, but what about potentially replacing that black cross bar with some bar that has the turbo mounted under it, or would it be too low?

If completely impossible, understood. Just really would love a kit for a 7AT.

wheee! · 12-23-2012, 09:00 PM

We might be flogging a dead horse here. The whole purpose of this kit was power and simplicity. The auto transmission is just too big!!

wheee! · 12-23-2012, 09:02 PM

Having said that, I understand your desire to have this kit!
