We love our 3.4 liter fully assembled shortblock, which uses the BC 94mm crank, custom JE Ultimate Stroker Pistons (select compression)and your own rod choice depending upon power expectations and application.

Why spend $15,000+ for a 3.4 liter short block, when we offer the exact same components (lets face it, everyone uses the same components) and many of the same machine shops everyone uses. Truth be told not a single major Supra parts business has it's own machine shop, not one, us included.

Once we understand the application of the motor (race only, fast street car, etc), then we machine the block with the tolerances required. Upon completion assembly begins and all tolerances are checked and then double-checked. Crank has already been confirmed rotationally during high-speed final balancing.

Pistons weighed, rods weighed. We cannot describe everything, but suffice it to say, its a comprehensive build. Rings are hand filed and all torque settings done using SnapOn instruments. You end up with a professionally assembled motor ready for install.

We use the same guys and just give you options with standard BC rods, Eagle, Pauter X-Beam (we love them) or if you are building a 9,700 rpm 1300hp motor Carillo H-Beams.

At SupraStore.com we have always strived to bring you the latest products and performance components for the absolute fairest value without any sacrifice in quality or performance.

The same holds true on our fully assembled 2JZGTE stroker kit fitted inside a seasoned Toyota shortblock. This is the same kit powering some of the worlds fastest and quickest Supras.

Years ago Guilly and myself used to think about boring and stroking the highly successful 2JZGTE engine and what affects it would have upon turbo spool and engine overall power. The naysayers said the motor would never rev out well. How does 9500 rpm sound for a stroker kit?

The naysayers said that the additional .4 liters of combustion space would not help that much in power and turbo spool. They were wrong. The additional .4 liters over the factory 3.0 liter motor makes a significant difference in energy production, which in turn powers the largest of single and twin turbo combinations.

The torque curve has also shifted downwards to make the car more driveable on larger turbo set-ups. Plus, the additional .4 liters with a free flowing exhaust just sounds MEAN! There is no sound like a SupraStore.com 3.4 liter stroker kit.

Designed by the pro's in California this true billet 3430 crankshaft, with a whopping 8mm increase in stroke to 94mm increases the supra displacement in conjunction with custom big bore, big pin, coated ultimate stroker JE pistons by almost a half-a liter!

Couple the stroke increase with the inclusion of stroker and big bore specific-designated JE pistons in 87mm (various compressions can be ordered) and we have created a 3.4 liter building block to unleash new levels of power, quicker turbo spooling and torque that Supra enthusiasts the world over have yearned for.

If your goal is a very fast 750-1000hp street car and you are not going to be a hard core drag racer, with the thought being you want to spool your 67mm turbo as quick as possible, then your ideal set-up is as follows: You can consider an 8.5:1 or 9.0:1 compression piston and the strandard Eagle rods or for slightly more BC H-Beam Sportsmen rods. You do not need TMS billet main caps on motors in the 750-1000hp range. If you will still be in this HP range and want to run E85 (exclusively then consider a 10:1 to 10.5:1 compression ratio piston set.

The combination of a higher compression ratio than the stock motor (8.5:1) and the .4 liters of additional volume are PROVEN to spool turbos and make power unlike any 3.0 liter motor. This is a legitimate 8,900 rpm set-up.

For those running exclusively E85 or any high fractional component of ethanol, then you can really bump the compression up and see significant advantages in torque. 9.5 to 10.5:1 is the standard range for E-fuel motors.

We are using the highly updated JE ultimate stroker piston with both skirt and dome coating, as well as the upgraded wrist pins, not generic pistons.

If you want to go up even more in power, then we love the highly under-rated Pauter X-Beam Rods. The truth is Pauter X-Beams are world class. I used to run Pauter motors back in the day and when they shouted to the world the new 2JZ world every tuner took notice! Top quality and lighter weight X-beam design. A Pauter rod motor will rev quicker than any rod combination we have and handle the power. Engineered and proven to offer same tensile strength at key areas as Carillo H-Beams.

Finally, if you are going ALL-IN with your motor and plan big rpm, 1300hp and/or nitrous, then Carillo H-Beam.

Why Us:

Custom Billet Crankshaft 94mm

JE Ultimate Stroker Piston Set:Coated Skirt and Dome Stroker Pistons 87mm (select compression) Rings and the upgraded Wrist Pins.

Eagle Connecting Rods (or your choice of other rods)

The initial questions we are receiving are in regards to comparing this kit to the HKS and JUN kits. There are four significant advantages of the SupraStore.com Big Bore Stroker over the competition.

(this is our editorial, not another companies that uses the same thing)

1. Crankshaft

The utilization of the billet crank is superior in materials choice and final robustness over the forged crank assemblies used by the others, allowing more rpm if needed. Pro racers are 9,500 rpm plus. 9000 rpm on a properly assembled street motor is possible.

2. Pistons/Rings

JE or CP Ultimate Stroker Pistons (you choose compression) are at or near the absolute pinnacle of the piston world when it comes to quality, design and materials selection for high performance useage. Ours include free dome and side skirt coating to help increase robustness and decrease friction. These pistons ONLY work with 94mm stroker crank, as they are custom designed not only in compression, but in pin location for the rod.

The ability to special order custom-compressions, which are not available with the other brands is an excellent feature. The rings and ring landings are standard for JE and are readily available. Break a ring on the HKS stroker kit and you are WAITING for a long time for a custom built ring from HKS Japan.

3. Affordability

Simply put, the SupraStore.com Stroker 2JZ kit is positioned in the pricing department to offer the first truly afforable Big Bore and Stroker Kit for the 2JZ. Priced well below the the competition, this offers the end-user outstanding value. We use all the big name parts and save you money!

4. Availability

Long the achilles-heel of many of the Japanese companies is product availability. Many of you understand that most of these companies simply do not bring enough product to the States to meet the demand.

The other kits are no exception with it's "special-order" ONLY status from Japan. Delivery times of 6-12 months is not uncommon. Our kit is designed,manufactured and assembled in the USA which reduces lead times substantially. Delivery times as low as 3-4 weeks (due to custom piston order) are possible.

Included in our build:

•Toyota Shortblock Magnafluxed (seasoned) * Add $1450 for outright purchase (price is based upon using your block).

•3.4L Stroker Kit w/ Custom Stroker Pistons (select compression)

•Oiling modifications to block

•Eagle 1000HP Rods

•ARP Main Studs

•L19 Std. Dia. Head Studs

•Spec Coated Bearing Set

•Align bore, Hone, Deck

•Blueprint and Build Short Block

We fully assemble the motor, provide all parts and palletize and wrap the short-block, so all you have to do is arrange freight.

Standard is the BC Sportsment rods, which BC rates at 8,200 rpm. You can change rods in the drop down menu. We use Pauter in our personal street cars and trust them at the highest level. If you want to save some more money and are okay with 8,800 rpm then Eagles work well in that range.

If you plan on making 1200hp+ or you want to spin the motor to 9,000 rpm+, then we suggest going with billet main caps. These are far more robust than factory caps and will keep the crank in place under big power or high rpm.

In order to install the billet main caps, they need to be torqued properly in the block and machined in a process called line boring. Please see the video below to get an idea of what line boring is and how it is done. Line boring can be done by any fully equipped shop with the proper line boring set-up.
