Ok now that I have a couple minutes to post.
Levi the common denominator between, the first motor that had unfortunate valve issues (that had the same part throttle issues) the LS, and this motor, vs your first GSR is.....
The Battery being moved to the trunk.
So because I can't stand to see this fail anymore.
Battery To BLOCK.
Block to chassis
Block to frame
Block to T-stat
Block to ect...
You get the idea now I am sure.
I agree with the grounds being looked at. I went into detail about a ground issue I had with him last night with my first setup that behaved MUCH like this one.
However.....
As far as common denominators go in relation to the problem....
You also forgot hat fucking clusterfuck of an injector driver and those faggot 1600s... He doesnt need them, and it WILL idle like shit (ill go as far as agreeing that a ground issue COULD definately affect them, but its gay and uneccessary). .
If it were mine it would get the ID injectors (I know they dont flow like 1600s, but there will be PLENTY for his goal, and they will idle WAY fucking better than the 1600s).
AS FOR IGNITION, i MADE WELL OVER 600 ON A BONE ASS STOCK JDM DIZZY STRAIGHT OFF THE CRATE. NO NEW CAP NO NOTHING.
SiMPLICITY IS KEY,
The only reason I run the 7AL2 is that Ross gave it to me for my birthday, and I know it worked as it was in Full Race Geoffs car.
Battery to block
Battery to chassis
Chassis to motor
All you should need.
Levi:
Remember to look at the ground with the four wqires in it that we talked about... It should be ground to your MOTOR, IF YOUR MOTOR DOES NOT HAVE A DIRECT GROUND FROM THE BATTERY, it is likely at least signifigantly contributing to the issue.
Fuck a battery in the trunk, LOVING my small ass Odessey battery in the engine compartment slung low... MY longest ground cable is about a foot long...
DOnt give up Blackness...
