    4AGE 16 valve swap into 78 Celica GT coupe?

    Hello all,

    I'm Justin New to the site and the radical world of Toyota's. I just got a 78 Celica GT coupe with a 5spd. The engine is on the downhill, so I found 16v 4age with trans, ecu and harness for cheap.

    I'll be starting the swap in a few weeks and was wondering if anyone might have some helpful advice or suggestions before I start. Your help will be greatly appreciated.

    Thanks, Justin

    Wow finally someone with a 2nd gen celica haha. Car looks nice. i wish i could help ya on that but im doing a ka24de. Go to 1stgencelica.com they have plenty of info. Even though there ment for the 1st gen the front end stuff is very similar. And also i belive club4ag has the wiring info and ecu pins for what each wire does.

    Why take a 2200cc engine out and replace it with a 1600cc one? Even if it makes a little more power, it makes way less torque...and your Celica is a fair bit heavier than an AE86. You should sell the 4A-GE to a Corolla or Starlet guy and put a 22R in there (easiest), or 2RZ/3RZ (best). AA63 is the only Celica that ever came with a 4A-GE...not exactly rocketships.




    Just my opinion though...

    18R-G is my personal preference for that chassis. :wink:

    I say either 20/22R combo hybrid or a 3RZ.

    I cant wait to see how this turns out. I am looking to pick up a 70s Toyota (although Im hoping for a first gen celica or a Corolla) in the next couple months and will likely end up doing this exact swap. I myself am not looking for a ton of power, just decent weight and a reliable engine.

    Do you have experience with swaps in the past? Do you have a decent garage and tool set? If its not asking too much I would be grateful for a good write up. I am gathering info on engine swaps right now, but havent seen many good write ups for putting an engine so new into a car so old.

    Here are some crapy phone cam pics (I lost my camera) of the engine. Needs some more cleaning up and maybe some paint. I think Ill need to modify the oil pan to clear the crossmember before it will fit.






    I need to finish this up before I can really tackle the swap.
