6G Celicas Forums

It really depends on how much effort you want to put in up front to make it work. Between Smaay, kurt95gt, and myself we have more or less documented every single aspect of the 1MZ/3MZ. The information is all over this site and will answer most questions you will have.


My thought on the 5VZ is that it isn't worth the extra time and effort to make it fit and work. No, it probably will not clear your hood, but I'm sure the 3VZ (and possibly even the 1MZ) lower and upper intake manifolds should bolt on and then you're fine. Same will likely go for the water pump. The beauty is that many of the parts are interchangeable... the problem is that you would be pioneering a bulk of the swap as it pertains to making it fit by building a Frankenstein motor, and wiring it together with the Celica's harness.


Best thing you can do is buy the motor, manual transmission, harness, and ECU from a Camry Solara and follow our documentation. I have a 94 1MZ in my MR2, and the problem you would run into choosing a pre-97 setup is that NONE of the 1MZ vehicles were manual transmission. This created a problem for me that I had to solve with a standalone EMS.








I guess what it all comes down to is how much are you willing to figure out on your own?

Well that is what I need your help for, I mean I have searched the boards and have done a little reading in just confused about wiring. If I got a vvti 1mz, manual transmission and ecu what would need to be wired in to the Celica harness. If there's a link to a detailed write up please shard

There are no write ups because all 3 of our harnesses were built by mr220v. The wiring has to be redone to use the stock celica fuse box an rerouted for the factory hole into the car for the ecu.
The wiringvgor both of those are on the wrong sides of the car in the stock 1mz harness
I'm sure. smaay an 95celicagt will both agree when I say having mr220v do the harness is your best option.

We've documented the Mz swaps fairly well on here but have yet to work with anything else

Yeah, granted mine is a bit more complicated as mine was into a MR2, but the headache of doing the wiring was something I was more than happy to punt off to MR220V. He returned to me a complete harness that had the fit and finish of an OEM unit. It made it all plug and play, and all I had to do was plug it all back in and route it accordingly. It would be best to label absolutely every plug as you remove it from the V6 so you know where everything goes when you put it back on.



If you don't want to pay someone to do your harness then you're going to need to look up wiring diagrams for both vehicles and figure out what needs to go where.
