Seriously...how many people build 1.9s for power? it's almost pointless to start with 88hp and port and polish to gain 2-3 hp. combine it with sohc and 8 valves, and all you have is a car that breathes a little better with 92 hp.onelatin8ball said:so you recomend not to port and polish a 1.9?????????? :?:
I'm sure there's someone out there that makes butterflies in any size you want...just port and polish, measure and get the right size b/f valve. You could probably do the same thing with the TB as well...TitoElSpicco said:i was about to start before i sold my EGT..
port the exhaust side of the head as big as i could go then port match the exhaust manifold to it.. it boggles my mind how much the 1.8's love the free-flowing exhaust. most engines like a little backpressure, my 1.8 ran it's best when it was a straight header with no exhaust at all.
does anyone sell larger butterflies for the secondaries on the intake? Porting the primaries is pointless since it will give you a loss in torque, and add nothing top-end.
and no - no kit i could reccomend - everything i've ported on my tbird was with a regular carbide grinding bit from lowes.
Uhhh.... well?egtdude said:well I say to the right person you can find a way to do it with a 1.9. Its designed isn't as well suited but I like a challange .
I have a little secret quick 40 HP trick I've been wanting to trying out... wish I had access to a 1.9
Check around mang. I'd love to know. The little butterflies are probably the biggest bottleneck to a 200hp n/a 1.8.James92Scort said:I'm sure there's someone out there that makes butterflies in any size you want...just port and polish, measure and get the right size b/f valve.

You're making me wanna call around to shops/manufacturers and find some so I can try it on Primer Guru's GT (my legendary(???) Escort).
