A turbo question...
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?

What about one of these?? Cheaper, current aero, good turbine options... 57mm Enhanced S200SX-E 7670 Turbo ? Full Race

You'll need to start by plotting your engine's operating points on the compressor map you intend to use to see if it's a close enough match.

P.S.-What do you have planned for ignition timing control?

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 😂
