your engine should be DOHC not SOHC, I'm guess you have one external cam gear so your thinking you have an SOHC when its a slave cam DOHC which would mean you have the 4AFE and the FE is not easy to get alot of power out buts its possible, but you end up putting in a lot of time and money so I've noticed, I have a 90 prizm with the 4AFE myself and all I have done is new NGK iridium spark plugs and took off the muffler that gave me better throttle response and more go but I don't know if it got any change in numbers, but seeing as you have already done exhaust and intake you should have pretty good get up and go

the only real thing I can sagest is higher duration cams, or even putting a bigger throttle body on her but the manifold would probably limit you on air flow

turbo it, or 7age it.
