My rear Subframe has never been dropped . . . but it needs to come out as there is a small hole that needs welding above it. I found a good Video where a guy leaves everything attached - just unbolts the Propshaft, bottom of the rear Shocks, rear Brake Calipers and then removes it with...

OK, thank you. Sending it to a guy who rebuilt his engine, but connected all the brown chassis wires (that connect under the Inlet Manifold) to +12V . . . I'm pretty sure he will have fried at least part of his ECU!

Forget the Code Reader . . . have you tried linking the pins on the Diagnostics port and reading the Flashes of the Engine Light to see what codes you get? (as per the details in the TSRM) Does the engine turn over OK? The radio has nothing to do with the ECU, so sounds like you have a power...

Will a 7MGTE ECU from an Automatic car fit and work in a Manual car with a 7M-GTE ? (both are Facelift models) I seem to remember it will . . . but can somebody please confirm before I send it. (Trying to help someone out who has blown up their ECU!)

Just love how it looks and how it drives. Took mine to a local Classic car Show at the weekend . . . lots of admiring comments, and not just from old guys. Lots of young kids really love it, compared to most modern cars! And what's my favourite thing about MY Mk3? Having a 2JZ engine in...

I've got a brand new one (boxed) I picked up cheap on ebay a few years ago . . . but waiting to get my front bumper re-sprayed before I eventually fit it!

Haven't read every single post in this thread, but just a couple of comments . . . It's certainly much easier if you get a 2JZ engine (and ECU) from a Mk4 Supra, along with all the ancillaries The Mk3 Temperature Gauge sender fits in the 2JZ block - I swapped mine so I knew the gauge...

Just to pick up on this discussion . . . as a long-time Mk3 N/A owner (15 years) who has also done a lot of research. In my opinion, when it comes to reliability there is no comparison between the the 7M-GE and the 2JZ-GE ! The 7M was one of the most powerful 3 litre engines when it came out ...

Nobody is telling you to replace your Head Gasket . . . yet ! Not until you've done proper tests. It's just that I doubt very much if your problem is down to the Rad Cap. Some of us have had a lot of experience of these 7M engines . . . myself it's 15 years . . . and we know all the regular...

If the plan is to replace the complete engine, then you can keep on driving and just top it up when it overflows - eventually it will be undrivable. However . . . as I mentioned, once coolant starts getting in the oil it will permanently damage the big ends - even if they don't fail straight...

I also doubt that the cap is your problem, I'm afraid. When the HG starts to fail on these engines it usually starts leaking INTERMITTENTLY. It can be fine for a couple of weeks . . . and then one day you will get pressurisation and tons of coolant pushed into the overflow bottle. When this...

The stock radiator is fine, so don't bother changing that ! (unless you're doing a 400hp modification) I'm afraid if you have water gushing out into the overflow bottle, that usually indicates pressurisation in the cooling system, due to a blown head gasket. As you're probably aware, the 7M...

I presume you just have ONE Cat (like on UK Cars), after the twin downpipes? Here in the UK there is no legal requirement to have a Cat, as long as the car still meets the Emissions Spec (which the 7M EASILY does!) And having no Cat does not cause any kind of exhaust smell ! HOWEVER . . ...

Are you using the 2JZ Aircon Compressor? (but with the head off your 7M one) The 2JZ Compressor has 4 wires coming off it . . . but you can remove all of those - just find the single wire that comes out of the actual compressor itself. You then attach that to the single wire that comes...

Have you thought about also offering just Plug n' Play adaptors, to save people having to buy a whole new (expensive) harness? When I put a 2JZ-GE in my Mk3 Supra, I obviously got the new engine WITH its harness and ECU all attached. Having spent dozens of hours comparing the circuit diagrams...
