how much would it cost to get my si on twin webers and approximatley how much power gains am i looking at.

[Stoned]

webbers are carbs mate and your Si is fuel injected

It wont work!

You wanna upgrade your injectors to get more power, but to be honest the Si 1.6 isnt a good engine to work with for power gains. You would be better getting a 2.0; engine

Thought it would work if you get separate management? Anywayz though, it wouldn't be worth the money for the pwer gain! Nothing is for the 1.6 mate.

prob 15bhp and awesome noise! but watch the fuel gauge drop, lol, u can stick carbs on nething, just have to get sep spark management about 350 i think+mapping

[makaveli662]

are u sure the power gains are that small. even if i ran it on 48's (if thats possible)

[zetec_si]

£500-600 quid will get your car running a 2 litre mate which would instantly give you 130BHP so why spend more to gain 15-20 BHP?

i think you can run fuel injected motor retro into a dual carb setup, you just need a new management system for the fuelling etc....
a lot of people retro fit zetecs into classic fords and remove the fuel injection in favour of twin webber of delorto carbs using a seperate management system...

have a chat to Burton Power, the website is at

they've got loads of stuff on this

urm i said u can run it , yeah well 1600 is an economy engine, 2 litre on 45`s would go like stink, 1600 is always restrictive, lol u shoud see the size of the valves!

[zetec_si]

What sort of BHP increase are we talking on the 2.0?

[snake]

slightly less than t/b`s cheaper as only need spark management, use more fuel though and requires settin up more often, think your lookin at 150-160ish on standard 2 litre, sound the nuts though

Also check insurance mate, changinf your engine to a larger siaze can be expensive and bring your insurance group of your car higher
