Our team at SupraStore.com have been involved in the 2JZ world for quite some time, with our founder - Mark owning the first stock block 1000hp Supra in the world all the way back in 2001.
For years people have been asking why you must pay $1500+ for a turbo manifold. I understand it takes time to engineer, test-fit, build a prototype, then build a jig, just to offer a header. This costs money and quality fabricators (check out our x-ray verified welds!!) are not cheap either. Our goal was under $1000 for a world-class hand-made manifold for the Supra community, which we have been a part of longer than any business on the planet.
We all know you can buy a manifold from China for $200 and at the end of the day, it is a manifold from China for $200, enough said. Our manifold is SupraStore built, we control it, we build it, we offer it to you for less. If it does not have our logo spot-welded on it, then it is a copy.
Our 304SS tig welded 2JZ exhaust manifold scavenges like none other on the market, with efficient runner designs and a proven collector. They are finished in a brushed-stainless "raw-look", but we can ceramic coat them at extra cost, if that is what you require. They are robust, handle heat cycles correctly and are guaranteed to perform.
The No. 1 runner is designed to provide maximum clearance for larger compressor cover turbochargers, while at the same time providing for an efficient overall layout.
QuickSilver turbo manifolds are offered in un-divided (standard) and divided for those wanting to run twin scroll turbos like the 6266 or 6766 from Precision, as well as QSV and Borg Warner EFR Non-Gate designs.
If you are using a Borg Warner internally gated EFR turbo, please make sure you select this from the drop down menu. EFR turbos are internally gated, which means we do not just clamp off the wastegate tube at the extension, but rather we eliminate it all together.
QuickSilver turbo manifolds are hand-made in a jig (to offer consistency) and have amazing welds, and the fitment is outstanding. The standard sized runners are 1 5/8" inside diameter and utilize .080" wall thickness stainless.
This design allows for higher velocity exhaust energy, while still maintaining significant flow. These manifolds perform outstanding up to 950rwhp.
For those with turbos larger than for example a Precision 7175 CEA (950hp), and for midframes, then it would be best to go with our mid-frame larger tube diameter manifold.
These are configured in either T3 or T4 designs. Why offer a T3 manifold on a 2JZ? Good question! The reason is simple, as there are many global customers who like the smaller T3 turbo's, so why not give them what they want?
Inside Tubing Diameter: 1 5/8"
Wall Thickness: .080" (2mm)
If you require a Tial, Precision, standard square gate flange, or other branded flange welded in, this is available as an option in the drop down menu. If you require another type of wastegate flanged welded, please select "Other" in the drop down menu and make a note in the comments section of the type of flange required and our staff will contact you to confirm details. If no wastegate flange is selected you will receive the manifold with the standard length wastegate tube "open" to mount whatever you want.
* Quick Spool Valve Turbo Manifolds are Available. Please see our other item listing for that specific version *.
* Our 3-year no questions covers any manufacturing related defect, including all welds and through cracking. The no questions asked warranty is for the original purchaser only. Micro-cracking of external welds in heat-cycled stainless has no affect upon performance.
ALL VALVES ARE NOW HEAVY DUTY VERSION, WITH THE OPTION FOR THE TITANIUM VERSION!!!
Okay, so you have read or are about to read what is below and you want the brief-no-nonsense quick opinion from SupraStore. Here it goes. The greatest single complaint we get from people switching from stock twins to a larger single turbo is LAG. Many people are just tired of having to deal with the lag of a bigger turbo. Bottom line, with the quick spool valve, your 62-67mm single turbo will spool quicker, hit harder and faster, and make much better torque and horsepower than your stock twins! End-of-story, read the stuff below for the technical nuts-and-bolts. What about bigger turbos? Same result: spool quickly, lag minimized, bam!!
Now that you are convinced, watch the video and notice the first two dyno runs without the quick spool valve in quick spool mode, you will see how long it takes after the driver put the accelerator to the floor for it to get on big boost and spool. Now, fast forward to around 1:42 in the video and watch the quick spool switched on. Pay attention or you will miss it, as soon as the driver nails the throttle, WHAM, BAM, it spools NOW!!
Oh - why buy from us? Simple, I have personally known Larry at SP for years, have tormented him back in the day and was running 900rwhp+ 10 years ago on a stock motor with one of the first SP74mm turbo's on the planet. That isn't a reason? Well, then, we sell it for LESS!!
Are you a hard core racer, running explosive anti-lag or 2-step blasts on your car? If so, worry not, as all of the QSVs are now the HD version for us hardcore enthusiasts!
This is one of the BEST upgrades for everyone running a T3 T4 or T6 turbo. The Quick Spool Valve has proven to produce as much as 150ft/lbs MORE TORQUE in the midrange of the powerband, AND it will make more peak power as well due to the turbo spooling faster.
The Quick Spool Valve has a butterfly valve blocking a scroll of the divided turbo housing, making the turbo act as if it were a smaller turbo. All the exhaust energy is routed through half the turbine housing, causing the turbo to spool at a much more rapid rate. In other words, the spool valve is essentially "halving" the turbine A/R when the valve is closed, and then you get close to full A/R when it is opened. For example lets say you have a .86 A/R 76GTS turbo. With the quick spool valve operating, at lower rpm's it acts like a turbo with a .43 A/R housing, which means it spools very quickly, shifting the power band downward on the curve and allowing for much quicker build up of hp and torque! When the valve opens, you end up with about 95%+ of your total A/R available and full boost.
Incredible for street cars!!!
The switching solenoid can be wired up to open at a set point and when the valve opens up, you have the full potential of your turbo with no sacrifice of peak power.
The Quick Spool Valve thickness is 3/4" so this is going to require either modification to the exhaust manifold or the downpipe to compensate for the height increase of 3/4". The valve sits between your turbo exhaust housing flange (sometimes called a footprint) and the exhaust manifold. All QSV's require final fitment by the installer and may require slight clearance mods depending upon the turbo.
People are asking, "how does it work with smaller T4 turbos? " Well, it works fantastic, as the design is not dependent of a large turbo, or for that matter, a large A/R. A 7MGTE owner with a 62mm turbo (see dyno sheet) was able on stock 7MGTE with SAFC on stock ECU to see a shift of 500-600rpm sooner spool, and a maximum gain of 50hp and 71torque at 3500 rpm! The red line on the dyno sheet is a dyno run with the valve closed; the blue line is with the valve open, as if there was no valve.
YOU MUST HAVE A NON DIVIDED MANIFOLD! If you have a divided manifold, we offer our own QuickSilver manifolds to suit your needs.
