So you’ve made it to this stage then you are ready to start pulling out the 2JZGE, make sure you have ample space in yours or someone else’s garage or workshop to work.

Ensure you reference the workshop manual for the process of removing all of the parts, and that you label them and keep all bolts/nuts together.

Begin by draining and safely deposing of all of the fluids from the engine such as;

  • Oil – Plug on bottom of sump and oil filter under intake plenum
  • Coolant – Plug under radiator, engine plug also at rear behind exhaust manifold
  • Power steering fluid – Remove any hose under reservoir
  • Transmission fluid *Optional if V160/V161 – Although recommended changing while you’re there

Remove all of the following;

  • Hood/bonnet
  • Battery, tray and clamps (Remove the battery ground leads always before working on any car)
  • Any wiring sensors/plugs you can reach
  • Igniter / Fuse box connectors
  • Intake system
  • Top and bottom radiator hose and overflow hose
  • Radiator, clutch fan and Fan shroud
  • Drive belt (Accessories belt)
  • Exhaust heat shield
  • Exhaust system
  • Front bumper assembly/plastic under-guards
  • Heater hoses
  • Charcoal canister and hoses
  • Throttle Cable
  • Power steering lines (On reservoir and steering rack)
  • Fuel line from fuel filter union bolt
  • Return fuel line
  • Clutch pressure line to slave cylinder
  • Ground wires that go to transmission/fuel filter
  • Grounds wire at the back of engine (To firewall)
  • A/C compressor lines *Optional – I didn’t remove these, I was tight on budget at the time, but if you do remove the lines please remove as per workshop manual. I would do this as it makes it easier than keeping hoses connected and working around the compressor!
  • Shifter assembly
  • ECU wiring/loom pulled out through firewall
  • Drive Shaft
  • Rear transmission support
  • Engine mount bolts

This article is a guide and summary of the work involved in swapping from a JDM 1998 Toyota Supra SZR to an RZ. Basically all steps involved in removing the 2JZGE and putting in a 2JZGTE VVTi, otherwise known as the NA-TT swap. For those that aren’t aware, the SZR came with the A02B torsen diff, 6 speed V161 and carbon fibre steering wheel, with my car it had only done around 50,000km (31,000miles) and was in great condition. At the time I did not have the budget for an RZ supra at my age and income, I came across a cheap 2JZGTE VVTi engine and thought this was the best opportunity to move to a TT, so I gave the conversion a go way back in 2006!

Toyota Supra Informational Video

Another Toyota Supra Informational video from the vaults, a Toyota Sales US video back in the launch year of 1993. Still to this day the Supra does not age, for those that watch the video please take note that the supra was probably closer to 4.9 seconds from 0-60mph for the US version. Thanks to Youtube user roliks.

If you know of any Toyota OEM or museum videos for the 2JZ either on Youtube or elsewhere 2JZGarage would love to see them, comment below or contact us directly.

REAS Suspension Diagram, Pictures and Information

Found in the 97.9-02 JDM Toyota Supra (RZ and SZ-R only) was the REAS suspension system – REAS (Relative Absorber System) shock absorber system.

I was lucky enough to have this suspension in my supra before I swapped it out a few years ago for some HKS hypermax coilovers.

I’ve posted a link below with some information on the system and also one of my favourite pictures of the supra, a chassis picture without the shell showing the REAS suspension.

Basically it was to improve ride comfort while still having good flat cornering ability. I’ve also put some pictures of mine when I pulled it out, I still have this available although I’m not sure if they can be re-filled or re-used.

(Translation from Toyota Japan – hence the japanese-english translation wording!)

REAS (Relative Absorber System) for comfortable ride and high handlings stability.
The REAS features an entirely new mechanism that functions not only to achieve a comfortable ride with a relatively small amount of damping force in cases like when both tires hit a gap in the road, but also functions to stabilize the body of the automobile against lateral “rolling” motion by adding a suitable amount of extra damping force and absorb the force acting in the lateral roll direction, as when cornering, when the pattern of depressions and protrusions in the road surface are different on the left and right wheel sides or when subjected to cross winds. Three main points of the REAS structure are as follows

1. The left and right shock absorbers have separate oil chambers with a REAS valve positioned on the connection flow passage.

2A single gas chamber is shared by the left and right.

3. Using the separate actions of hydraulic fluid and gas, a separating piston is activated by the coupled movements from the right and left.

2005 – IS300 Service Manual

Thought I’d had these posted but realised I hadn’t, this is the 2005 IS300 workshop manual pages. These come in handy for the VVTi guys due to the VVTi head torque and specs, most apply to the 2JZGE and 2JZGTE VVTi figures.

Most of these documents are applicable to the J-SPEC and Europe-SPEC supras. There might be differences to driving side, wiring and some features and functions.

Supra and 2JZ World Record 1/4 Mile Runs

E.Kanoo Racing has just broken the 2JZ World Record again, 3 major records were smashed with their 10.5 Outlaw 3/4 chassis supra driven by Garry White;

Fastest Toyota Supra
Fastest 2JZ powered vehicle
Fastest Import

Congratulations to the E.Kanoo Racing team, hopefully GAS motorsport can bring the record back to Australia 🙂

E.Kanoo have also beaten the IRS supra record, running a 7.12 @ 201 mph. What a great achievement!

Video is a mini documentary and both runs are in there.
