There are four different generations for the 3S-GTE, and the most sought after are 3rd and 4th Gen. From 3rd gen onwards they made a lot of changes, making it more powerful and tougher (especially if you want to turn up the boost). But of course it costs more than a 1st/2nd gen, so be prepared to pay at least $2-3k for a decent motor, and then more again if you want to include a newer E-series gearbox (If I recall correctly, the g'box in your Celica has seen better days!). And then maybe more again if certain parts are not included, like an ECU. Sometimes people also sell them without turbos and stuff. Also, don't forget the cost of changing all the oil seals, all the gaskets (except headgasket hopefully), the timing belt, water pump, dizzy cap and rotor and leads, and a few gallons of oil to flush the engine a bit.
The early gens are still decent though, and they will be much cheaper. I'm guessing you don't want to spend a ton of cash on this car!
Considering that this is now your daily driver, the best option might be just another 3S-GE. You can probably find a second-hand motor for like $500-800, and it will just drop in and go (after changing the seals and stuff, of course).
A reco'd engine will probably be about $1k. A fully rebuilt engine will be more like $2k+.
And this is all before fitting. These are all just estimates anyway, so you will need to call up places in Perth to get an accurate idea of what it will cost. I don't know if things tend to be more expensive or cheaper over there. Maybe get GT to recommend a shop for you.
Anyway, I'd say your go-faster-dollars are better spent on the other Celica
Just get this old guy moving again.
