Vac secondaries dont work on a 6 port either. Racing Beat changed their Fc NA carb kit to come with a mechanical secondary carb. They initially sold a few vac secondary carbs but they didnt work.

Whats the difference between the carbs exept that you pull the secondaries open with the link instead of the vacuum? Does it also have a secondary enrichment pump in the secondary passage? I got here a carb for a streetported early 13b 4port engine with the secondaries linked.. but that carb is pretty fucked up..

Secondary accelerator pump on the mechanical secondary carbs.

Carb can arrive any day.. Hopefully is ha the 2nd accelerator pump and linked secondaries.. It's no problem for me to link them put probaly when you floor it at low rpms it will stumble somewhat I think..

Just a quick question about your oilpan.... Would the 13B one from the GSL-SE not fit, or did you just have two 12A pans hanging around?

Rub20B

It could have fitted.. didn't have one..



I had 12A pans enough so I had to go that way..



S4 TII pan has other front cover..

Got the carb..



The secondaries are vac controlled :/



Intake manifold lines pretty well up to the engine.. so making an adaper plate will be doable..



The primary runners and 2 middle bolts line up perfectly..
