I have a 12a turbo and I've heard good and bad things about a locked and unlocked distributed...
I just want to here what some of you got to say, and maybe help me decide what to use.

 

Locked. Unlock = Boom.

 

n/a needs more advance as rpm increase, thus mechanical advance. Turbo cars incease compression via boost, mechanical advance = certain detonation!

 

is there anyway i can go with an electronic setup

 

if you go with a stand alone, efi set up from a tii. but why on a 12a?

 

The primary injectors have the bungs in the center iron, all he would get would be secondary injectors unless he welds more in.

 

my bad

 

yes you can go electronic. I have a haltech in my car and personally think it's the only way to go. The amount of control over all aspects of the car is phenomenal. Carbs are cool, but efi is tha' ish

 

locked

 

couldnt i get more power if i made it electronic?

 

A megasquirt n spark would allow custom fuel and ignition programming.
The low tech option would be to recurve the distributor. You would want the opposite of what is typically done for a V8 drag car.
They use light springs to get earlier advance while you would want stronger springs and possibly braze in the slots to limit total mechanical (centrifugal) advance. Some work on the vacuum advance may be helpful to get best cruise economy.

 

thanks the low tech way doesnt sound bad for now, where could i find stronger springs that small, also when they weld the dizzy where do they weld it, is it by the springs inside the dizzy? when you remove the bearings?

 

If you weld it you won't have springs and you'll weld the weights in the fully advanced position, and figure timing off that.

there are many threads that explain this in far more detail than we can get at here.

 

lol yea i got tired of looking after the 3rd page lol but ill get back to it thanks alot though

 

An auto electric shop or a speed equipment dealer should have the springs.
If not you can lighten the weights to get a similar result. You would need to disassemble the distributor to do these mods. I prefer to braze the slots to limit the total advance. Welding is usually more "permanent" IE non adjustable. Welding may also distort the plates in the distributor that run in tiny ball bearings, potentially resulting in binding or inconsistent vacuum advance. All bearings and bushings must be reused.
