6G Celicas Forums

Ok,
Haven't been on the site in a while, just thought I would post some info I have on the 3sgte for anyone who is interested in rebuilding one. I don't know if anyone cares about this or if this is a repost. I got this info from the prosis database at my college today during my engine rebuilding course, I already have my engine rebuilt so I was just checkin engine specs and helping other people. Also, the engine shop has a 3sge and two 3sgte's as demo engines. I am eventually going to rebuild a 3sgte and swap it into my celi, but for now my project is a 69 buick skylark that I am swapping a 425 olds big block and th400 trans into (360 hp and 465 lb.ft. of torque....stock ) anyways, i'll shut my big mouth now and post some of the info, if you need more specs on any other engines, let me know.

Thats all for now, I know not everything is complete, but it is some info for anyone who is doing some work on the wonderful 3sgte engine.

Good information, would be at home in a 3SGTE FAQ whenever it is compiled. I'm sure all of that information can be found on one's own, but you did us all a favor by making it one big list. My thanks!

do you know the exact year and model that is from? there are slight variences on some of the different models.

This was listed for 90-94 MR-2 and Celica All-Trac. There will be slight variances depending on your application, but for the most part, these figures will be similar for most 3sgte's.

your the man

Thanks\\//
