If there is too much positive pressure in your block it will restrict your oil being returned into your pan, increasing the oil pressure in the turbo causing oil to seep past the rear piston ring on the shaft.
Finally got a hold of some is coils.
Here are the coils inside the 1zz coil bracket to see what changes I have to make.
Pretty sure I will have to open up the 3 holes and turn them into rectangles so the coils sit further in.
Also the last coil needs to be clock at a slight angle so it...
I also am running the MP-70
Made 508rwhp at 18psi.(14.7psi creeps to 18psi by 7500) on my 1jzgte last month. On a .68ar
Going back on Jan 22nd for the 28-30psi. I now have a .81ar housing on with shimless buckets. 8500-9000 rev is where I wanna be.
Shimless is lighter and you won't spit a shim on rev or antilag etc etc.
You you have shims, it is easier to do valve clearance, shimless the cams have to come out and they are twice as much.
Shimless is like $13ish for a bucket
Shims are like $7ish each
Usually it is a fuel cut for two step iirc. Antilag does a spark cut, that's why you get the explosion tht can backfeed.
I also have a high pressure ratio. 3:1 in my manifold. So also could be bad, that's why I went with the .81ar housing
