2jz into a70 questionsa70 mk3 supra 2jz
Posted 08 July 2015 - 12:38 PM
Im looking at getting my hands on a mk3 supra and swapping a 2jzgte into it. has anybody got experience with this?
Im not quite at the stage of requiring a walkthrough but just planning ahead.
Is this something that i will need an Engineers certificate for?
Also, i have read up a guide on how to convert to a "1.5jz" , where parts of a 1jz are left in the car and parts of a 2jz are added, what is the benefit to this?
Is this to avoid complications with governing bodies/getting an engineers certificate, or does it make a stronger motor?
If a straight swap for a 2jz is the best outcome what will i need in total to make the swap? this will be my first project and my first conversion, looking to do most of it myself as i have mechanical and electrical knowledge.
Thanks in advance!

In my opinion the 1.5JZ is a waste of effort. The original idea was that the 1JZ head flowed better than the 2JZ head, so you would have the bigger displacement block with the higher flowing head, however I recall seeing actual flow test results that disproved the theory that the 1JZ head flowed better. Yes, shops in Japan do this, however shops in Japan do a lot of things that aren't always the best, sometimes due to parts availability and cost.

I can get my hands on a very clean ga70h with the 1G 2.0l motor, would this model have the engine mount locations necessary to make the swap to a 2j?
And once this is done will i need an engineers cert? Or can i just advise vicroads of the engine number update?
Thanks once again
