I'm piecing together a 12a dellorto low boost (5-8lbs) for my 1980 626. I have a rotary works 12a exhaust manifold and tial 44mm external wastegate. I need to make a decision on a turbo. Here is what I'm looking at:
Goals are a fun car. No drag racing or competition. 12a is stock port and I won't be running an intercooler. Thoughts?
I would say your best bet is to go with a turbo the same as a turbo II fc or the same as a race tech kit from the 80s if you want a fun ,fast and street friendly car . I would also not be afraid to throw 15lb at the 12a .
Thanks Matt. Problem is I already ponied up for the fancy manifold. I have an fc t2 turbo and manifold but would have to modify heavy to work on the 12a
Locked dizzy with leading timing at 10-12 degrees adv. trailing at 0
Taking the centrifugal advance springs out should work fine, that's what I did for my blow through setup a while back. You may want to see if you can find a JDM 12A turbo dizzy. It's all setup by Mazda to work with boost.

Redirection was necessary and steps have been taken
I figured timing was critical and since oem pulleys are notoriously variable I got this Found some rot to be dealt with so this had to happen Got an rx2 manifold and a s4 turbo with 12a fitment Some time with a grinder and some high temp paint will go a long way toward making this look presentable Turbo that came with the manifold is seized but I have another. Jeff20b might have had something to do with recent decisions lol 😂
