I'm reading and learning., keep it coming as my brain is like a slowly dripping sponge!!
I know the feeling! I had about a year and a half of that while I figured out the Microtech MT8 and then the Megasquirt 2!
PS WTB non cracked piazza turbo manifold and any late model 4zE1 head with closed chambers!
Uncracked Piazza manifolds are almost nonexistent, I've been looking for one just to complete my backup/original setup, and I know of two others who are looking for one too, the problem is half of the people selling them don't care enough to look properly. Also if you find one, hot tip, don't try to remove the EGR bolt, that's how I cracked mine...
My two cents, don't run a T2 series turbo on an E1, they're just too small for it. Even my GTX3071R's 0.64 rear is borderline too small, well in my opinion it's just right but I have ridiculous boost creep with a 38mm external gate, it goes to show how much exhaust gas is trying to get through, it's creeping to 25psi in the top end so I just expect a T28 would nuke itself. Even an older (and cheaper) T3 turbo would go well on an E1 I reckon.
Hey Ant - I'm probably going to try 4x DIYAutoTune IGN-1 coils as the specs are good on them, I've heard LS are good but on paper the IGN-1 and IGN-1A are better - time will tell if the specs are accurate in the real world...
