Hey fellas,
Doing some homework on dropping the 4Z into my car and i need measurements. What i need is someone thats done the swap-mount way [swappning the gemini mounts left to right] to run a tape measure over something for me. Plan on doing mine this way because the engine sits nice and far back.
What i need is the measurement from the front of the gearbox plate to the radiator support where the radiator bolts in.

Can't give you exactly what you are after but this thread will tell you how to modify stock engine mount brackets to centre the engine perfectly between the wheels.
It will also show mod of the mount to raise of lower the engine height (without adding spacers cos spacers muck things up geometry wise).
Then all you need to do is adjust where the engine sits forward or back. And I suggest for this a test fit engine, with the modified brackets tack welded and the dissy in place (because the dissy clearance of fire wall is usually critical) to confirm the final adjustment needed to the mounting bracket.
Also keep in mind that there is no rule that says an engine has to sit perfectly vertical. A cant of a couple of degrees to the left may help with that dissy clearing and not be an issue with fuel bowl levels in carbys etc.

Hey Toby,
Was actually flicking through your one just now along with sandys swap run through. Ideally id like to do it leaving the mounts around the standard way as it looks like it can be done/clear the firewall judging by sandys pics, worst case itll be a left to right swap adjusted to sit straight. At the moment im just chasing the measurement so i can see if my hair-brained idea will actually work.
Dizzy clearance wont be an issue, its a 4ZE1 which will be modified to run coil on plug, possibly off the crank pulley. Also no carbies to worry about either.

That's who ive been discussing this with. In a moment of madness he took his 4Z out of his car and put something ugly inside insteadLOK15 wrote:jonno??? paging jonno????

Re: 4Z in Gem roll call
I ran my engine mounts around the normal way. I modified the heater fan cover originally because I ran a piazza dizzy. I've since changed to a 4ze1 dizzy with no cap as a crank trigger with coils. it clears the firewall ok (10mm to spare). I'd avoid using the mounts around the wrong way because the gearbox will have to come to far forward. even with the mounts around the correct way the gearbox still had to dome forward 10mm. 4z blocks are shorter at the front and at the rear.

Re: 4Z in Gem roll call
Yeah i know about the front shorter bit. Overall my 4Z is 525 end to end , vs 615 for my G series. Reckon you could do me a favour and run the tape measure on your car for me?

Ok, with my engine mounts around the normal way the distance from the gearbox/engine mounting face to the radiator support panel is 695mm. Hope that helps.

And I don't have the specific measurements
