Bigport down draft setup

[CRO747]

Hey guys I'm looking at building a 4age bigport for my ke70 and I want to run a single carb setup with dizzy, has this been done ? Does anyone know whereto get manifOld from? Any help would be great, I also have a fairly big Toyota supercharger and was think of running a blOw through setup anyone done this or know how to go about it ? Thanks :)

Whats wrong with efi? Could probably order a manifold from a v8 workshop as they have redline catalogs, I would think it would also be easier to stay with efi if your going supercharger.

My uncle has a workshop and he is pushing me towards carb I tend to like it too he has resources and knowledge for that aswell

Fair enough, may aswell go twin sidedrafts if your going carby.

Single carb set up with distributor.....is your uncle about 70 years old?

Blow thru turbo/ charger is a pain to get right, + you need the right carb for the job and most are for v8's or you need to make a box for the carb...... Should go efi cos it will cost less in the long run and run better. I tried with a corona ended in fail (d'-' )

haha hes around 50 lol we talked today and are probably going to go twin side draft instead,

Why not just get an aftermarket ecu for it and wire that in? You're taking a massive backwards step by going to a carby setup. Will cost you more to get twin carbies a dizzy and coil setup to operate it all, plus a shitload of effort to get it working, when the most basic aftermarket ecu could have the whole thing running in a couple of days if you wanted.

Sorry to sound negative, but just because old guys know carbies doesn't mean it makes it cheaper in the long term :P
