I think you are saying can you put a 4A-FE in a 90 celica GT... I'm not sure if you can, but why not just put a 3sgte, or a 5sfe in the celica gt. If you put a 5sfe you don't need a new harness or ecu or anything... just the engine.

Hmmm maybe he want the 5S-FE in his ST. You'll need everything: wiring harness, engine, engine mounts, tranny, axle, ECU. 4A-FE and 5S-FE are different series engine, they don't "drop in". So with all the cost for swapping a 130HP 5S-FE, you can do a 200HP 3S-GTE.

I thought it says he wants to put an ST engine in a GT? isnt a GT a 5sfe already? or is it a 3sfe?

Sounds to me like he wants to put a 4A-fe into a Gt which has a 5S-FE! But why down grade. The 5S-FE in the GT is better than the 4A-FE in the st!!!

Pinneaple, your missing radiator and one of the most difficult things. The passenger side motor mount bracket relocation. You have to get the motor mount bracket from a gts or gt off the junkyard, cut your old one off the st, & get it welded on the same gt location. St - gt is to expensive for very little horsepower gains. Go 3sgte on the st like I did. You will lighter than a gt and faster than an alltrac

well yea i wanna put the motor out of an st into a gt temporarly because the motor in the gt is siezed up and the one in the st only has 50,000 miles on it but the body is smashed in the front end and the gt has a pretty good body but how much do the 5sfe,s cost usauly for a decent running one.... im new to owning a toyota

5S-FE are cheap. Many people selling after swap. Check the forsale section and local junkyard, japan import shop.

yeah... I would of givin you my 5SFE for $100... but I stripped the car and sold it off anyway. so you might get lucky and get one for $200... CHEAP
