Since you have all these toyota motors around, is there anyway you could compare an S series head with an MZ series head, or the deck on the block?
Id be interested to see how well they match up, a 1MZ-GTE would be pretty badass. Maybe its feasible to shave a cylinder off the head if the bore spacing and waterjackets match up. Ive seen someone weld two v8 heads together for a straight 6 before, so anything is possible.

Any recommendations for a specific mz block for reliability/ease of swap for my daily college/pizza driver? Lexus or Toyota block make much difference?

They're the exact same. A 1MZ from a 94 Camry is the same 1MZ from a 94 ES300... and so on.

to make the swap the easiest, i suggest getting a 1MZ out of a 5 speed car. that way you are not dealing with ECU issues chasing Auto codes

Agreed. 97+ ANYTHING Toyota/Lexus that has a V6 minus SC300.

Smaay I need a little info to see if it's worth venturing into it. It's in relation to the coilpacks on the 1MZ-FE.

How many pins do the plugs to these have? I want to know if they have inbuilt igniters or if they're just coils. Also, how long do the boots for the plugs measure in inches?

the igniter is an external box just like the 5S. the coils i believe are only 2 wire and they are wasted spark meaning 1 coil feeds 2 cylinders. This is for the non VVT 1MZ

the VVT 1MZ and 3MZ are 4 wire i believe just like a 1ZZ or 2ZZ. they have the igniter built in i think.

you can see here the 2 wire plug on the side and the spark plug wire that runs around to the back 3 plugs.

So these are just coils... hmm.

I'm going to run a wasted spark setup for now but I wanted to clean the bay up a little. I was thinking these would look cleaner. I could use these but Id rather use some with inbuilt igniters because it's better, noise-wise (less noise inside the megasquirt with the bip373s) and less heat as well.

Are the 3mz coils the same? I mean wasted spark, or individual COP?

sorry i didnt see this sooner, the 3MZ actually went to a 4 wire coil on each cylinder so now there are 6 of them.

Oh so true COP then. Thanks for the info. Do you happen to have any of those laying around?

sorry i dont

I'd love to hear this thing. Has there already been a video posted of the exhaust? I might've missed it.

oh yea i rem. needs to be redone without wind.

i live in Lancaster, its always windy here. ill try to take a better video.

How are you making out with the VVT? I am getting ready to drop a 3MZ into my 94 ST, and am currently sourcing the ECU. I have a ton of options, but they boil down to 1MZ with manual ecu, or 1MZ with VVT ecu, nothing with both. I'd really like to get the VVT working, but don't want to fight all the auto trans codes.

Also, how do you determine if ECU has immobilizer?



This is a fantastic tip!

Just giving an update, the car is running as strong as ever. Im chasing an AC issue. i think i have a leak somewhere.

UV dye and a black light.

That crap blows... Hopefully it's just an old O ring somewhere. I managed to crack one of my hard lines in one of the times I pulled my motor, then I made the mistake of trying to replace them with the motor in the car. I got it finished, but it would've been a lot easier with an empty engine bay. Then again, if it's something I've done, you've done it ten times and you're a hundred times better at it.
