How To Get More Power Out of a 2JZ-GTE Stock Supra Engine - BPU

The engine replaced the past Toyota 7M. The 2JZ is a simple sort of a straight 6 cylinder motor with a hard cast iron cylinder block and 3 liter displacement. Comparing with the 1JZ, the block of cylinders became 14 mm higher. A crankshaft with a longer piston stroke to 86 mm. The motor is like the 1JZ. It has got two camshafts and 4 valves for each cylinder. The engine is equipped with an ACIS variable length intake manifold. Since the VVTi system was added. There are no hydraulic lifters on the motor. The valve clearance control is needed each 60, mileskm of mileage. Firing order on the 2JZ is The 2JZ has a toothed timing belt. Its life span is 60, mileskm of mileage. The quickest and craziest Toyota Supra engines horsepower were made of the 2JZs. The 2JZ was produced from to Their specifications are given beneath. It has got a compression ratio of The first modification produced till had compression ratio of Its capacity depended on settings and varied from to horsepower. The capacity remained the same. The motor was improved with CT20A turbochargers, intercooler, and the other pistons fitted to compression ratio of 8. The connecting rods were borrowed from the 2JZ-GE and the injectors are cc. Such engines developed a capacity of horsepower at rpm. Due to those factors, the capacity of the exported 2JZ-GTE engine was increased to horsepower at rpm. The 2JZ failures were similar to those of its younger brother, the 1JZ. Water can pour onto the spark plugs if washed. Due to the presence of the VVTi and idle control valve sensor, there can be problem caused by rough idle and so on. It is HEREwhere you can find out about all common problems. The 2JZ is extremely safe and durable. If your motor has been properly maintained and only a high quality engine oil has been used, the 2JZ engine lifespan will comprise more thanmileskm of mileage. Although, some basic principles are worth mentioning. You can certainly buy all the necessary performance cams, ITB, do head porting, mount an aftermarket intake system, headers and performance exhaust system. When the engine has been built, it will develop not bad capacity, but the 2JZ-GTE equipped with a simple boost-up will be more powerfull and simpler. You can also buy a 80 mm throttle body and adjust it on the Greddy E-Manage. As a result, you can get about horsepower. The boost-up is to the first step to upgrading the engine. For doing that, you need to get a big intercooler, huge radiator, oil cooler, air filter, Toyota Supra US lph fuel pump, and injectors. The stock can be remained or you can buy cc stock injectors.

All rights reserved. More on this:. Up Next. The 2JZ-GTE engine is known to have a lot of unexploited power amount lying in its six cylinders waiting to be unleashed. Most tuners can get it to around hp with stock internals by converting it to single turbo, changing the ECU and adding some bigger injectors along a less resistive exhaust. This includes updates to the intake, exhaust, downpipes and boost controller for starters. You should know that the BPUs should be made all at once to get the most out of the setup. Now comes the actual turbos. These are the main components that will give you more power through ramming more air in the cylinders. The stock turbos are making 11 psi 0. If you have a JDM engine the turbos are ceramic and can safely handle about The 1. To make the turbos go faster and make more boostyou need to free up the exhaust. Which means to take out the catalytic convertors which highly restrict the gas flow in the exhaust pipes. There are two catalytic convertors, one for cold engine emissions and one for when it gets hot. Tuners will offer completely de-cat exhausts or some that will ease the gases flow but not disable them completely to stay in the emission levels. Latest car models:.

Bore and stroke are Compression ratio rating is 8. The 2JZ-GTE has an oil spray nozzles to aid in cooling the pistons and a different head with redesigned intake and exhaust ports, cams, and valves. As a result, this engine produced PS kW; The second generation used VVT-i system on the inlet camshaft and was manufactured since The output power remained the same, but peak torque was increased to Nm The breakdown of the engine code is as follows:. The cylinder block, a monoblock specially cast structure, employs the seven bearing support system. The crankshaft has seven journals and twelve counterweights; both pins and journals are induction-hardened. The pistons are special aluminum casting. Each piston is fitted with two compression rings and a single oil ring. The surface of the top compression ring is chromium plated. The cylinder head is made of a light, strong aluminum alloy with good cooling efficiency. Camshafts are made of specially cast steel and are driven by a timing belt. The 2JZ-GTE engine is equipped with four valves per cylinder: two intake valves and two exhaust valves. The Toyota JZ engines are not equipped with hydraulic lifters, so special valve shims are used to adjust the valve clearance. Valve lifters are available in 17 sizes range from 2.

I have a 2jz na-T and its at 16psi with whp on a. So what is the limit on an pistons? When do they fail? My tuner is concerned that pushing any more will make the reliability go down significantly and possibly damage the ring lands since its not the turbo pistons. THMotorsports New Member. Your tuner would be corrent. You can take them up to sub hp, some have done more but for what time period? That being said, save up, build a block and replace. Thank you. No Way Man. Staff member. Super Moderator. Joined Apr 17, Messages 12, Location Tokyo,jp. You could do that. Are you running stock ge head gasket? The gte hg will lower the compression ratio allowing for more boost. What are you tuning with? So after some forum lurking and reading flamed threads i have came up with a plan whp goal 2jzge stock head replace 2jzge rods and pistons with TT parts they come with arp bolts for rods and npr rings and new wrist pin bushings TT head gasket mojo lq9 coil on plug conversion e85 tune lph walbro use factory hard lines. Seeing as pump gas is max of 16psipsi. Joined Mar 30, Messages 1, Location Abalama. I would keep compression Especially if you are standalone.

2jzge piston limits?

In the hands of the right tuners, decimation is what the Supra was all about. It was a high point for the Japanese auto industry, and the 2JZ was a high-point for big, tough, iron-block straight sixes in passenger cars. Toyota only puts big straight sixes into trucks now, and its big rear-drive sedans have V6s. Any couple schmucks can drop a few thousand dollars to buy a 2JZ to cram into some old Nissan if they want to and make a high-horsepower car in their garage. The 3. Those high performance GTE models received different aluminum cylinder heads with unique intake and exhaust manifolds, higher-flowing injectors, recessed pistons offering lower compression ratios which allowed the engines to handle more boostand oil squirters to keep the pistons cool. Because of these differences, the GE models, which you can find all day in Lexus GSs, are not as desirable in the tuning scene. That was a brazen lie. And in the U. Between the power, and the pound-feet of torque at 4, rpm, the Supra instantly became a force to reckon with despite its prodigious weight the engine itself weighed over pounds. The car could do zero to 60 mph in under five seconds, according to contemporary tests, making it a very quick car in its day. That was stock. Nobody kept the Supra stock. Way too much could be gained if you messed with it. Its iron block is tough as nails, its seven main bearings—despite only being held by two bolts each—are absolutely gargantuan and hold the crankshaft firmly, its forged counterweight steel crankshaft can handle huge power and high engine speeds, the oil pump and water pump can take the heavy mods without failure, the fully-closed deck means the engine can withstand enormous cylinder pressures, forged connecting rods are stout, and the oil-cooled cast aluminum pistons can handle a beating as well. Yes, horsepower on stock internals. And many tuners have cranked theirs into the four-figure range with some more work. Though there are a couple big-bore and stroker kits out there, most high-horsepower 2JZ-GTEs get that grunt by way of changing out the intake and exhaust, swapping those sequential turbos out for an enormous single turbo 67mm is commoninstalling a bigger front-mount intercooler, and bolting on some bigger injectors and fuel lines. It was an advanced engine in its day, and forit became even more so, as the Japanese version got variable valve timing. Sadly, the U. Technical Editor, Jalopnik.
