Hi,
I am from the UK and own a 91 GL hatch. It comes with a d14a1 with dual keihins from stock and a vaccum advance dizzy.



I have recently bought a D16a9 and an ZCspeed inlet adapter allowing me to bolt the carbs up of which looks like so....



Sorry about the terrible quality.

Now i have two vaccum advance distributors one from the SOHC D14 and one from a Brown top D16a1. Both of which do not fit the pattern of the D16a9 :(. Is there anyway i could make either fit?

I am sure i could fab something up to make the SOHC dizzy fit which would be prefferable but would the car run okay? Just to note the D14s do not have an ECU. Unfortunately i still don't wuite understand all types of ignition system so when it comes to igntions curves and advance i still have alot of learning.

Any info would be greatly appreciated,
Many thanks,
Lee.

This would be a very good shout. But finding a 3G prelude over here would be extremely hard. The only ones i have ever seen are b20a's and they are fuel injected last time i checked.

I really don;t want to have to spend out on aftermarket management if i don't have to. As my budget is very tight as it is.

i think you would be best off with a spark controller like MegaJolt

or see if you can rig up the distributors to bolt to the head with spacers/ears. as long as you can synch it properly and it wont move, it doesnt matter how its secured there...

I totally agree with you Danz, but i am poor :(.

Also the B18a distibutor doesn't fit.

''Honestly, since you're going to use a carb on the B20A, you only need the distributor out of the 86-87 D16A1. The TDC/Cyl sensor on the exhaust cam is useless to you. The distributor is a straight bolt on part. No need to modify anything'' This was taken from a 3G prelude forum.

Unless i can find a way to use the d16a9 dizzy and ECU, but i am unsure about how to go about it.

I should be able to modify the D16a1 distributor to work with at least 2 bolts but it is a bit ghetto IMO.

Yep. I hacked up some tabs on a B18A distributor and made it run my D16A6 when I was caught in a jam a few years back. Long as you can hit base timing and still secure it, it's good.

Cheers chaps. I have found that if i can get hold of a cam cam from a ZC1 then atleast one bolt hole will line up.

Thanks again.

Also this is going to sounds newbie, but quite fitting when you look at my post count. Can you remove the rotor arm on a ZC1 distributor as it doesn't have a screw like the rest of the honda dizzys i have come across.

I tried all the intuitive things albeit with caution, being trying to pull it off and screwing it off but nothing happened.

Ok just to be clear you need to know that the jdm and edm accords came with b18a and b20a from the 86-89 is different to your b20a from the 3G prelude and the b18a of the civic

What you are looking for is the carb model dizzy b18a from the jdm or edm 86-89 accord

I have a contact in new Zealand who can source this for you if you want but check out the int version of eBay they might have it too

Best of luck if I was you I would rather go with megajolt
