Personally... I've yet to hear about anyone doing a successful 5SGE n/a build. Granted it's great for a turbo set-up... but n/a... I don't think it's worth it.

This is off another celica website hope it helps. So in your opinion how much time/money would it be to do this conversion on an existing 5SFE? exactly what parts do you need?

Well, the problem with doing this with a car that already has a 5SFE is that you would have to change the whole top end. You would need the 3SGE head, 3SGE intake and exhaust manifolds, 3SGE electronics (injectors, VSV's, etc.), 3SGE wiring harness and 3SGE ECU. It's still entirely possible to do though. If you have access to a donor car, here's what I would do....

DONOR CAR
-Disconnect the wiring harness from the ECU.
-Remove ECU
-Unbolt the boot for the firewall pass-through and pull the harness into the engine compartment.
-Disconnect the harness from anything that is staying in the car
-Remove the timing belt
-Remove the valve covers
-Remove the head with the intake, exhaust, and wiring still attached

YOUR CAR
-Repeat the above procedure with your car, then install the parts from the donor 3SGE car.
-You will need a good wiring diagram for both cars showing the pin placement for the ECU plugs, then you'll need to make sure all the wires are in the right places for the ECU wiring that DOES NOT go to the motor, ie. dash lights, guages, etc.
-Work out the bugs!
It will definately be alot more work and time consuming than what I did, and I'm not sure how much better a 5S"GE" would be than a 5SFE...

yeah basically from what Ive been told, you are practically doing a 3s swap and leaving your bottom end.


worth it? up to you. I was going to give it a shot but money was an issue, maybe next time lol tongue.gif

The question is not how far. The question is, do you possess the constitution, the depth of faith, to go as far as is needed?
