[5S-FE] : Engine Rebuild Questions (Forging, Headwork etc) Options

[Syaoran]

Hey everyone,

So I'm looking to do a full re-haul of my 5S-FE. Long story short, I was deciding whether to keep my Celica or not, and I've decided I will, and I'll just build it completely, starting with the engine. Later on I will work on getting either an S54 from an MR2/6GC or an E153 from a Solara locally. Keep in mind I'm in Puerto Rico and parts aren't easy to come by, so I have to work with what I have available and get the best out of everything.

POWER:
Basically my goals are 300-350whp. I'm going to get Colt Cams (260* .345) from the group buy on here. I'll be boosting it after I'm done with the engine work. Will most likely go GTX3076R or something similar

RELIABILITY:
I want to crack open the engine and replace all seals and gaskets with OEM or better (cometic headgasket, arp hardware, etc). What should I do to the head/block while it is out? Simply port and polish the head, bore the head to match my forged pistons, micropolish the crank journals...

I'm willing to listen, and I want a pointing in the right direction. Thanks in advance.

Thanks for the input, hope someone can clarify as well.

Would I need oversized rings even if I got overbore pistons (.040" over 3s-gte pistons are 87mm just like our 5s-fe block stock bore)
