 Howdy Ho people
I have a 83 Corona st141 that i got for free. It had some front damage but a hammer and some extras fixed it.  Apart from that it looks bran new.
Now I want to get a faster engine.
I have the standard 2S-C and dang it boots compared to all the other coronas i've seen with that engine so i'm wondering if the person who had it before added some things on.
I was thinking a 1g-gte engine for it. I've looked up on the net for the cost and most of them cost about $700-1000.
Does anyone know the cost of the conversion i want to do it myself. I have lots of spare time
Anyone know what needs to be changed/Brought n that?
-------------------------------------------------- -
Apart from that if anyone know what can be added/replaced/attached without changing the engine to give it that extra shwing can ya tell me
Any extra info i need to know about the car, engine ?

Get in contact with 7M-Brisbane, he got 90% through a 1G conversion in his ST141 before he sold it. It's a relatively straightforward process as far as engine conversions go.

I documented a lot of it.

Definitely don't buy a bare engine, buy a complete half cut. They come complete with everything (intercooler, engine, gearbox, etc).
It's not the easiest of conversions, personally if I had my time again I'd have gone for a rotary or another 4 cylinder such as an SR20. As much as both of these are done to death, they will fit much easier and be less of a pain to work on in future. Why mess with somethign that works?
1G is certainly doable, it's just not as simple as some claim it to be.
A 3SGTE is a good option, however there are apparently some issues finding a traditional RWD gearbox to suit, as well as a few dramas converting them to a traditional RWD layout.

If its 2S-c powered it would probably have a w45 box thus bolt the bellhousing to a W58 or something and a 3S to the other end and apparently you can use some of the 2s bits to convert a 3s to RWD??

the 2S corona came with borg warner box and rear end
not suited for 3S conversion, the SA63 celica is the best candidate for 3S conversion.

Every ST141 I've seen had a BW 4-speed box and rear end.
