i have a 92 legacy na 2.2l first ibelieve it has single exhaust ports. i'd like to find headers and do cams next. just wondering should i look for differant heads at the same time, easier to find headers ,posslibly better flowing, did they make 2.5 heads sohc? any help would be appreciated.

 

ps anyone installed a groupa throttle body spacer?like it?

If you're 2.2 in your 92 Legacy is the stock one, it already has dual ports. All 2.2s were dual port until 97.

so will any of the 2.5l dual port headers work... borla etc.

i'd like some opinions are the gains in increased valve size worth the loss of compression when swapping a sohc 2.5 head onto a phase 1 2.2 block, so if anyone has two cents throw them my way. also planning headers and cams, if i stroke it will i need new pistons to restore compression if i don't plan on boring it any it will remain a na build
