I have CELICA GT 2004, It has 6-speed tranny, and blown GT engine vvt-i and I installed GTS engine vvtl-i in it, It started good, but what else do I need to replace maybe wire harness and copmuter?

Did you swap the tranny in too, cuz the GT's didn't come with 6speeds, they came 4 speed auto or 5 speed manual? Also, please better explain what is working, and what is not working.

Yes, You need the GTS ecu at the least. the GT on wont control lift.

I haven't done (or seen) this swap, but if it's like most toyota>toyota swaps you'll need to splice the old and new harness together.

I know you need to add the Lift circuits to the harness. Other than that I have no idea since I have never done the swap. Look up the wiring diagram on each engine and see whats different. Then you will know.

Id go to mr2oc.com and do what the Spyder guys do when they swap. Should be exactly the same thing for you.

There's a lot of information for this over on newcelica.org. For starters, I know you need at least one new engine mount and a GT-S mid pipe for the exhaust. You'll need the ECU and harness for a 2ZZ as well, and the harness is plug and play if I'm not mistaken- at least I've never seen any posts saying otherwise.

the 6 speed came in the GT overseas, so that answers that part. as for the swap, you need a GTS header, ECU, passenger engine mount, and need to add wiring to run the lift. i have it all documented here.

The GT downpipe will not fit the GTS header so that will need to be modified or you need a GTS downpipe.

you will have to change the pins on the plug for the TPS sensor.

you need a GTS heater hose from the head to the heater core. the hose with the big dip in it will fit fine.

you also need the GTS throttle cable from the cruise to the TB.
