Non VVTI to VVTI?
Hey guys, i was just wondering,
From a 93 Sc300 OEM 5-speed, with a non-vvti motor, what would i need to do to swap in a vvti motor, lets say from a later SC300, or an is300, if thats possible?
Im assuming i would have to switch out alot of wiring, and the ECU. Is it plug and play? Seeing as most motors are A/T ECU's what would i have to do to make it work.
Thanks alot in advance, im completely clueless when it comes to swaps.

Why would you want to do that??? The vvti motors are weaker than the non vvti ones are.
If you are gonna go to all the trouble of a swap at least get a 1jz and make it worth while.

They have weaker rods so if you plan to modify later on they dont hold as much power. Honestly do you think its worth all the hassles of swapping motors etc.. for 15hp???? You do know that youll have to convert from OBD1 to OBD2 so if the state checks your ECU with any kind of scan tool (some check the "check engine" light for codes) they will know instantly its been modded (OBD 2 only came in 1996+ cars) and they will probably give you more hassle than if you just did a 1jz swap (at least 1jz is OBD1) and no its not plug and play it would require just as much work/risk as a turbo swap.... Only without the benefit of boost.

im not swapping the motor so i can get 15 hp.
I have a high mileage motor, and im just looking for viable options in-case the one i have does go.
And i know there are members with 1jzgte swaps on the forum in CA, but like i said, thats not a viable option for ME.
Thanks.

Well i dont know how many miles you have on your car but my old SC has well over 260K on it and still going strong, i know of a several others over the quarter million mark with no issues either so if you maintain it they will last a LONG time, Since you are in cali if it goes bad you should have no issues finding a lower milage stock GE laying around to put back into it for a couple hundred bucks from someone that has done a swap.

I guess if you want to be prepared for when your engine dies. You will need a non VVTi engine, to keep it CA smog legal.
Reason why I say non VVTi but not OBDII it's because you can use your wiring/and ecu to convert the OBDII to an OBDI. There wasn't and VVTi OBDI so... you are out of luck.

You can do that if your car came with vvt-i, like a 98+ SC/GS/IS etc.... then you can stick an older bottom end onto it, or you could just put stronger rods in the vvt-i block since thats the weak spot.

Honestly man its a waste of time, most people that are wanting serious power switch out the cams anyway and go with off the shelf HKS or some custom grind, there is a reason the guys that make big numbers use a ported GTE head with cams in it, no need to reinvent the wheel here........
