Outer Limits 4x4 Board

G'day all,

Just wondering if any of you guys on here have used weber carbs on ur 2.6 astron 1 engines and your overall impression on the swap ie power increase, driveability etc.

Cheers Dan

I had twin DCOEs on my Sigma, but that's probably not what you wanted to know about...

Yes, Weber conversions are common, but these days a conversion to Magna EFI is becoming popular. Search this forum for posts by member mrx78u, or have a look at www.sigma-galant.com

Thanks mate,
Yea just doing a bit of research for the old man, who is strictly carbs for offroad. Hes got the 4x4 l300 van with a fresh 2.6l astron 1. So im just poking for info on the weber downdraft 32/36 or 38/38 swaps that are apparently popular with these engines.

Cheers Dan

Yeah mate, I had a 32/36 on my first Sigma, and with a mild cam the thing was great.

Then again, I also had one with twin 48 side draughts and 5 grand worth of motor work, now that was unf#@kn believable!

hey all,im about to put two of these 32/36 on my 2.6,im making a custom plenium that welds to the std manifold.i had thought of using a rotary 4 barrel as they ar eexcelent carbs but could not find 1.cheers ill get pics sn.

Do you have an idea of what jets you will be running? Have you tried a single before?

Cheers Dan

na i havent got that far yet im picking up my manifold today,so hopefully ill be up to the jets tonight.i havent tried a single on a astron yet but have had them on heaps of other motors.im guessing it shold be somewhere between a single 32/36 and twin 40s.well see tomorrow or later tonight.

ok ..update,i only just got my manifold back from the welders,in the mean time i got bored and slaped 1 32/36 webber on a spare mani and it hauls.it has std jets (what ever a cortina has). hope to have it running with the twin soon.

Any more updates? Would u mind telling us what the std cortina jets are if you take the carb apart?
Cheers Dan
