My car wasn't burning oil either
When I had the blown turbo

But concerning the engine swap
Its either you stay with the 7m or go big with the 2jz
I really don't see the point of the 1jz swap
Since it has a 2jz bottom,
When the top part of the 2jz is the most important,
I'm going 2jz too,but idk if its gonna be with the mk3
I'm thinking of going mk2 with a 2jz
Cuz a mk2 with a 7mgte is a freakin rocket
Like the other guy said
And I have been told numerous times
That it can work
