Hey guys,

 

I have 32/36 weber sitting at home waiting to be fitted to my 5k, but i have not fitted it due to it being jetted for a standard 4k.

I was just wondering if anyone could send me in the right direction, in relation to jetting.

 

List of modifications to the 5k :

 

Engine rebuilt

Extractors with 2 inch exhaust

11:1 compression ratio

bored out to a 1600

Crow cam and hardened pushrods ( Unsure on the lift, but its big)

Heavy duty valve springs

Balanced crank

Flywheel balanced and lightened

Dizzy recurved

Gt40r Coil

 

Any answers would be appreciated!!

Get it on a dyno, there's so many variables that affect jetting. It would be a shame to have all that work done and not fully unleash it's potential.

I was hoping to do it myself, but i may be able to get my car on my mates dyno for cheap. Just thought someone on here may have done similar modifications and i could go from there.

I'm sure someone can get you a baseline that will get it rolling. I've got a boring 4K with just a shaved head that I could give you the jetting from if you're stuck. It would be a reasonable way off though.

This is true! I was thinking maybe i could use the specs off the 2l escorts, as they use the same carb. What do you think?

Weren't these carbs on a 1.6 as well? Somewhere between the two would get it moving.

yeah, i think so. Can you use a 4k dizzy on a 5k?

Yep

Thank god for that. I think my vac advance diaphragm has a leak on the 5k dizzy. Luckily i have a couple of 4k dizzy's sitting around:-)
