Skip, I have looked into engine conversions for CA. Call your local BAR Office and request the guides on engine conversions and the listing for what engines/smog equipment is needed for your yr Supra. The link below for engine conversion is generic in my opinion after talking directly to my local BAR.

ie you can legally use up thru an '89 Supra engine to be installed in a '85 MK2, key point no mention of what engine 7mgte/7mge can be used :lol: You must retain ALL smog equip for the chassis and ALL smog equip must function. Probably a point of contention is using newer engines most newer engines MKIV/SC300/GS300 etc use a 3 way cat and OBDII/III, etc these eng would not meet the letter of the law since a 85 MK2 uses a 2 way cat of sorts and no OBDII/III. But I have seen a 92 7MGTE legally converted into a MK2??.

You will have to take the car to a referree station for certification and the chassis will receive a engine conversion sticker when passed.

Sites to check for more info

'86 Supra MA67

been searching all over the internet for this info. i have
found info on some websites, but im looking for something more OFFICIAL. i checked the DMV site but couldn't find it. can someone point me in the right direction.

ALSO: ive been seeing alot of this from what i've been reading...

"as long as the engine is the same year (or newer) as the vehicle."
"Motor, ecu and emissions equipment must be the same year or newer as the car it is being installed into"

what exactly does it mean by "newer as the vehicle/car"
please give me SUPRA related examples. thanks.
