ok the main reason i wish to know this is because i can most probably get my hands on a 1G-GTE motor with an unwell bottom. can i just drop most of the 1G-GTE onto the top of my 1G-GEU, like cams ect and it will run fine??? Because compression is govened by the heads arn't they? and maybe the pistons.
Compression is goverend by the pistons.
To run the 1ggte properly, you'll need the 1ggte ecu.
