Spare sr engine more power?

[dangeestarlet]

Got a nice 60k 4efe out of a sr here and going to keep it for my other sr so I want a build a high compression 4efe, is fte anthena head gaskets same as 4efe ones? What else can I do to increase power? Port and polish, head skim etc , just want more power and don't want to do a turbo conversion as it's a sr want to keep it as it is with 4efe

Arent athena ones thicker? Think trd do a 0.6mm one to bump up the compression, maybe skim the head a bit too.

Custom cams or 5efhe ones.

Itb's/glanza/corolla inlet mani.

exhaust mani

exhaust

management And a map.

Obviouslt freshening up the ignition system would help also.

Not to sure , il have a look for a trd one, what would be the most that I could skim off the head ?

I got a mani back exhaust system so will keep an eye out for manifold,

Thanks

standard gasket is 1.2mm in both the fe and fte. If you want more compression the TRD gasket (0.6mm) is an option or i think the sera ran a 0.5mm gasket.

The TRD gaskets are discontinued now! They where 0.6mm. Ive just got one off mikey on hear as a spair lol

Want to sell it ? 😛 what about a fte head? Would that make any difference in performance wise. Is that a standard sera head gasket or you mean trd one?

All you will gain from a FTE head is better valve springs, turbo cams are not the best for a N/A 5efhe cams would work tho. And no I dont want to sell the gasket lol I know how hard there going to be to get hold of!
