hey people, i am currently trying to get my efi sorted on my 4age bigport, but i am having some problems.. and now my plans for the motor have changed and id like to go carbi.

 

whats the deal with a dizzy, do i have to replace it with a carbi one or can i change the internals or can i leave it as it is?

also I'm going twin webbers, is there any special requirements/mechanical work needed that i should know about other than removing the throttle body/intake?

and is there anything else i need to change other than those 2 things?

This should tell you everything you need to set it up:

This should help you tune it:

I have a 5k electronic distributor that has been modified to suit 4age that I will sell

Send me a pm for more details

I would persevere with EFI.

 

Bite the bullet and buy the three looms, ideally from a zenki AE86, from Yahoo Japan.

 

Won't cost much and will likely solve your issues.

I'm looking at a possible supercharger later on. an after market loom and computer would be costly and I'm finding it hard to sort the efi as my rolla was orginally carbi before i converted it. i have been offered a twin webber kit and dyno tunig for $400.

also, what about all the plugs, like the two on the back of the engine, would i just unplug them from the loom or??
