Supra dropped its first name, and with the introduction of the fourth generation model in late 9. Paseo. All of that was mostly because of the MKIV Supras factory turbocharged 2. JZ GTE powerplantan inline six cylinder engine so ready to make sobering sorts of horsepower that, even 2. L just as they did decades prior. And for good reason. Few production engines before or since are capable of the sort of outlandish horsepower the 2. JZ GTEs good for with so few modifications. WHERE TO FIND ONEHere in the US, the 2. JZ GTE, which was a clean sheet design, wholly independent of the preceding Supras 7. M GTE, was available only in 9. Supra Turbo models. In Japan the 2. JZ GTE was introduced in 9. Toyota Aristos hood and survived within select Japanese Supras until it was curtains for the car altogether in 0. The 2. JZ GTEs naturally aspirated and easier to find older sibling, the 2. JZ GE, is based upon the same short block and nearly identical but higher compression rotating assembly, but as far as Toyotas concerned, is only good for about 2. You dont care about these. Stay away from them by not looking underneath the hoods of non turbo, fourth generation Supras as well as Lexus IS3. GS3. 00, and SC3. THE JDM ALTERNATIVEOverseas derivatives of the 2. JZ GTE include the 1. JZ GTEa destroked, 2. L version of the familiar cast iron longblock of which later versions featured variable intake cam phasing and a single turbo. Even the 2. JZ GTE was updated for the Japanese market in 9. VVT i treatment as the 1. JZ GTE with updated turbos. But you dont live in Japan and, chances are, the engine you care about is the North American bound 3. L that makes more power and made you want the Japanese made supercar since before you were old enough to reach the pedals on a Huffy. But you should JDM engines are easier to source, less expensive, and just as capable despite some of their shortcomings, like smaller fuel injectors and cams. ITS ALL ABOUT THE BLOCKToyota took cues from Nissans circuit owning RB series of engines when developing its 3. L 2. JZ platform. Like the RB2. 6DETT, the 2. JZs inline configuration lends itself to a design thats naturally balanced. Unlike V type engines, half of the blocks rotating assembly doesnt get tossed around in opposite directions from one another. Watch the 2. JZs mess of pistons and rods spin about and youll notice its front three cylinders do the opposite of its rear. The even distribution of weight means the typical polar rocking motion youll find in a V 6, for example, isnt there. All you care about, though, is that the design means you can rev it higher longer, safer, and smoother than just about anything else. Being able to double power levels may not seem like something a simple engines capable of, but thats sort of what make all of this possible. Looking for an engine capable of 7. Build it out of heavier duty cast iron instead of aluminum, give it a solid deck to ward off cylinder movement, stuff in a forged crank, and tame the compression ratio with dish shaped pistons just like Toyota did. A series of seven main caps keep the crank from shifting and under piston oil squirters cool the rotating assembly and keep it lubricated at high RPMs. Toyotas people also carefully considered the engines geometry, integrating the elusive square shaped design where bore diameter and stroke length are one and the same. Aside from a temperamental bracket that secures the tensioner in place, an oil pump seal thats notorious for pushing itself out, and a crank pulley that likes to come apart, failures dont occur often, according to Southern California Supra expert Ian Sai Ngarm of FSR Motorsport Creations. JZ GTE The Good Bad. Pros Capable of 2,0. Tightly packaged, inline configuration. Non interference valvetrain. Bulletproof cast iron block. Forged crankshaft. Massive main journals. Under piston oil squirters. Square bore and stroke. Timing belt, oil pump, and cooling system capable of 1,0. Cons Failure prone timing belt tensioner bracket. Oil pump seal can blow out. Crank pulley can come apart. Poor flowing cylinder head. Failure prone sequential turbo system. HP THE EASY WAYMore than doubling the 2. JZ GTEs power output isnt hard, according the guys at FSR, but ditching the sequential turbo system for a larger, single compressor has got to happen first. First, look for a turbo in the 6. Both GReddy and HKS offer upgrade kits that include everything you need to do just that. Youll also need a higher flowing fuel pump, larger diameter delivery lines, 1,0. ECU, like AEMs Infinity, for example. Aftermarket cams like those from Brian Crower will make getting to that 7. MORE POWER THAN YOULL KNOW WHAT TO DO WITHThe 2. JZ GTEs already proven itself worthy of belting out more than 2,0. Youll need more than a 6. Start with something in the 7. Larger diameter head studs will keep the head from lifting off of the block. Even bigger cams and head porting have also got to be addressed here, and if you dont want to run out of fuel, look to 2,0. Celica lineage you want to get. GENTLEMEN AND THEIR AGREEMENTSThe 2. JZ GTE translates into a seemingly conservative 3. North American bound models, and theres a reason things seem so timid. Since 8. 9, Japanese automakers have avoided expensive horsepower wars by capping production car output in its homeland to 2. At least on paper. This Gentlemens Agreement has since been broken, but the once settled upon but often not followed terms meant engines like Toyotas 2. JZ GTE left the production line with a whole lot of unsqueezed juice left in them. At the time, the agreement made a lot of sense for a country with a maximum speed limit of 6. American car buyers who who expect moms minivan to make more power than a mid 9. All this means to you is that turning 4. JZ GTE with a few bolt ons any numbskull could handle is easier than you think. SEQUENTIAL BOOSTToyotas 2. JZ GTE gets all 3. Hitachi turbos codeveloped by Toyota that arent a whole lot different than the T3 turbo you once stuck on your Civic. Unlike parallel twin turbo setups where two equally sized turbos huff the same amount of air at the same time, sequential layouts allow one turbo to do its job first and the other to join in at higher engine speeds. Often times a smaller turbo precedes a larger one, but with the 2. JZ GTE, equal sized turbos sit at both ends. The Supra was one of the first cars to prove that sequential turbocharging didnt have to be clunky and unreliable. Here, by 1,8. 00 rpm the first turbos already online. Stab the throttle, let the ECU, wastegate, and a couple of bypass valves do their jobs, and by 4,0. JZ GTE PARTS GUIDEBrian Crower Cams Aftermarket cams like those from Brian Crower are one of the best ways to shift the 2. JZ GTEs powerband into a more effective range, making the engine a whole lot more efficient. The company offers three stages of cams that are suitable for everything from daily drivers to full blown drag cars. AEM Infinity Programmable ECU The Supras cast iron block is strong, but without the right tuning, itll blow to smithereens just like any other engine. AEMs plug and play Infinity ECU connects right up to the Supras engine and chassis harnesses and allows for complete control over everything thats going on with the engine and a whole lot more. View Photo Gallery 2. Photos. GReddy Turbo Upgrade The 2. JZ GTEs factory turbos will only get you so far. As it turns out, a single turbo overhaul, like something from GReddy, has got to happen if you want to get serious. GReddys single turbo conversion kits include all of the important bits, like an equal length exhaust manifold, an external wastegate, and the turbo itself, with options serious enough to allow for nine second time slips. Honda Swap What Fits What. We kick off Part 2 of our Honda Swap Combinations writeup by taking a look at the H series VTEC motor from Honda. First found in the 1. Honda Prelude Si, the H2. DOHC, 2. 15. 6cc four valve engine that put down 1. Despite the impressive power numbers, Honda enthusiasts once upon a time found the H series motor to be the black sheep of the Honda family. Once you have your engine removed, you can begin planning the best H series swap possible. Fast forward a few years and as technology has given us tools to improve the H series engine, the attitudes of enthusiasts toward the H series  has also changed. With parts like the H2. B adapter plate, which allows you to use a B series transmission on any H or F series motor, it really changed the game for Honda swappers. H2. B adapter plates truly have changed things for H series swaps. For the Honda Prelude the H was reworked to increase displacement 2. These changes resulted in the H2. H series motor that produces 1. The H2. 3 was first created for the Ascot Innova, while the H2. JDM Honda Accord Si R in 1. In 1. 99. 7 the H2. This raised the bar to 1. Later the same year came even more improvements for the H series, with higher 1. Honda then put it into the Prelude Si R Type S, another model we were never graced in the US with. Cool Car 9. 58. 19. USDespite the H series advantage in displacement, it never took off the way the smaller and more accessible D and B series engines did. In fact it wasnt until well after the arrival of the K series in 2. H series motor wasnt more appreciated by enthusiasts and Honda fans. Deserving of the black sheep label or no, the fact remains that the 4 cylinder H series still stands the test of time from naturally aspirated standpoint. Like them or not chances are you arent going to get the same level of reliability and power from an aftermarket all motor standpoint. What Do I need to Swap a H into my 1. OBDI Single Cam This covers the 9. Honda Civic EG and the Del Sol, and unfortunately this will require a custom swap mount kit. Hasport and HCP are just two of the manufacturers that produce H series motor mounts. In discussing the H2. H2. 3 swap into a Civic, well be addressing the stock H series hydraulic transmission. If you are looking into a H2. B transmission swap, scroll down to that section for details. OBDI H2. 2 or H2. This single swap provides the largest gain in horsepower and torque while staying true to the Honda all motor roots. With this swap youll have a huge gain in power, and huge improvements in low or midrange rpm. Transmission Because the H series hydraulic transmission works differently than the rod actuated transmissions of the D and B series, this is the biggest change when it comes to swaps. You will most likely require a custom mounted shifter box, where your stock shifter floorboard must be cut open and the shifter box mounted. Wiring  If your Honda was not originally equipped with VTEC, this will have to be wired. Other sensors that didnt come in your car naturally are going to have to get wired. Click on the links for a primer on How To Wire VTEC or Wiring a H series. ECU  The P1. 3 or a chipped or modified P2. P7. 2 will work great here. Again if your Civic or Del Sol did not come equipped with VTEC, check our How To Wire VTEC article here. Axles A simple call to Driveshaft Shop or buying an aftermarket swap axle kit is of course the easiest way to go about the axles for your swap. If you wish to use a frankenstein combination of Honda parts, you will need the inner CV joint of a Prelude Accord for it to snap into the transmission past the circlip. The passenger side 1. Acura Integra Axle with the inner CV joint will get the job done. The driver side 1. Acura Integra axles will bolt right in. What transmissions can I use for my H series swapFrom 1. USDM Honda Prelude VTEC carried the M2. F4 five speed transmission with a final gear ratio of 4. From 1. 99. 7 2. H2. U4 five speed was equipped with a 4. Most people looking to transplant a JDM engine anyways will opt for the M2. T4 five speed that came in the 1. JDM Prelude Si. R. This transmission came equipped with a factory LSD and a similar 4.

Complete swap kits are now available, making this swap a breeze. With this H2. B kit it will allow you to not only bolt on a B series hydraulic transmission and retain the rod actuated shifter, but it also allows you to use B series clutches and flywheels. With better gear ratios and a bigger selection and variety of bolt on transmissions, this modification truly has redefined the H series engine swap as a whole. Engine Specifications.
