Its been almost 2 years since I've picked up my 620 and after diagnosing a rod knock I have have since rebuilt the motor

 

-l20-.20 over stock rebuild,

-U67 w/ large factory intake runners

-Z therapy-1800 SSS Carbs

-81ZX 5spd. with 40k miles

-Exedy clutch

-1800 Exhaust manifold

-2" Manifold/back exhaust with turbo muffler

-Coolant temp sensor

-Oil pressure sensor

-fuel pump

-Plug/wires/cap

If I were to guess, this is about $3000 worth of refreshing-Labor excluded.

After 2 years of owning this little truck, It finally runs, and it runs WELL. Very well. 

 

My HOA threatened to tow it, got raped on a set of carbs, raped on some faulty donor parts, and felt like throwing in the towel more than once. All in all i'm glad I followed through. 

 

l20b (.20 over), u67 head with big intake ports and big valves, Z -therapy - SSS SU carbs, and a ZX 5 speed. Gotta say this combo is fun, fast and agile. The only thing i had sourced out was the engine machine work and the tuning of my carbs, by a Z car specialist. 

 

Enjoy the pics and videos.
