So..I put OEM SR20DE 9.5:1 pistons in my SR20DET...
So to be honest..It wasn't intentional, but interesting that it kinda worked anyway.
A couple years back i had a machine shop do the assembly on a rebuild and they said they could also order the factory pistons.
Without thinking what that meant, I went ahead with it. ( I intended to put factory DET pistons in it ).
After the engine was complete I had it dyno tuned on a mustang dyno with the following:
Stock rods
Stock injectors
Stock fuel system aside from Z32 filter / walbro pump, also stock fuel pressure.
Stock intake manifold.
Nistune
HKS GT2510
256/256 cams
Tubular bottom mount manifold w/ full exhaust
91 octane gas @ 17psi
Results:
366whp / 310ft lbs tq
I was maxing out the injectors so the low boost = low tq.
I ended up having my drain plug back itself out on the dyno that day, lost all oil and killed the turbo.
fast forward 2 years: at some point during a injector upgrade/turbo swap, or maybe even the same day I killed the turbo..my ( DET ) piston rings are toast.
Pulled the head yesterday and discovered my mistake from the build.
Even though it wasn't intentional, i figured I'd share anyway as I've never heard of it being attempted.
