Not sure on the others, but avoid Jasper or ATK. My Jasper 22RE has burned well over 1 qt of 20W-50 every 1000 miles since I got it.
It's at about 15k miles now (well past any break-in period) and still doing it. Junk.

Does anyone know if EB builds and ships complete longblock 22res? Honestly, I have decided that I may just go straight Toyota factory if I replace this Jasper. Expensive as hell but the thing will be set up right with the right parts.

1989 reg cab pickup, 22re, 31s, 4.56s, rear ARB, rear OME springs, RS9000s, otherwise stock.
