The 3S-GTE in my 1990 GT-Four has recently overheated and blown the head gasket and damaged the head. It's currently with the good folks at Canberra Toyota for examination for further damage. The engine is original and hasn't been re-conditioned or modified in its 14 1/2 year lifespan. I suspect it'll require a total rebuild, and while I'm sure Canberra Toyota will do a good job, they'll be expensive and I'm wondering if they're my only real option.
My two principal questions are these:
1. Are there any good Toyota engine re-builders in the ACT region (incl. Queanbeyan)?
2. Apart from re-building the 3S-GTE, what are the pros and cons of other options which I might have, for example:
(a) replacement 3S-GTE, including that from a GT-Four Group A Rallye;
(b) replacement with another Toyota engine (e.g. Supra turbo);
(c) replacement with another engine (e.g. WRX boxer turbo)?
