Delta Camshafts

[William D. Robinson]

Does Delta make performance camshafts for the EJ22T turbo?

By the way, about twelve years ago I rebuilt my 83 Mazda 626 and had Delta Camshafts of Tacoma regrind my cam and rocker arms.

When I installed them, the car ran very poorly then catastrophically puked, well before it ever warmed up.. A rocker arm snapped and tore a hole in the head. I had a machinist check it out and he determined that the rocker arms had all been mis-chucked. Delta freely acknowledged that they mischucked the rocker arms, but insisted that their responsibility ended at replacing the torn up cam and the rocker arms that they ruined. I was stuck with a freshly rebuilt engine that was full of metal particles from all the abrading that happened before the rocker arm snapped. I had to throw in a wrecking yard engine. Delta's sloppy workmanship and their refusal to accept responsibility for it cost me an entire engine.

Good luck if you use Delta Camshafts, you'll need it.
