Modification to 3S-GE Gen 1 engine

[Norky86SX]

hey guys.

I own an 1986 Toyota Celica SX, with the 3S-GE engine, and recently had the head repaired, and now im looking for some extra power.

i was thinking about forced induction, but with the 3S-GE compression ratio, i think that would be a bit dangerous... any ideas?

Edit: 9.2:1 compression ratio, turbo an option?

already done the exhaust, with extractors and a sports exhaust.

IMO dont bother turbo-ing a 3SGE (although it can be done), just swap to a 3SGTE.

I've written an article on modifying 3SG's. it does not cover turbo conversions as i have a separate article on the turbo engines.

see it at www.roadandtrack.net.au.

Doesn't that article specifically not mention Gen1 3SGEs though?

Would it not be cheaper and give a higher turbo pressure turbo putting a 12Psi in then swapping for the Gen 2 GTE?

Are you still interested in a 3sge head?

PM me, Rick

It might be cheaper, initially, but it will cost you more in the end (believe me!) and you can run 12psi on a stock Gen II 3SGTE if you get a boost controller for it.

Throw in a 2 or 3gen 3sgte and build from there. Much easier getting now. Unless you want mild power extractor and aggressive cams?
