I spent the better part of 2017-2018 fighting some motor issues. Went thru 2 NA-t builds to test the limitations. Melted the pistons on the first motor and cracked the ringlands on the second motor.
The 3rd motor was supposed to be a built GTE with a 3.4L crank, forged pistons and rods. There were multiple red flags since initial start up. The motor was purchased from a trusted builder and a friend that owned a shop. But when it comes to money, no one is your friend. That motor spun a bearing and died a week after it was dropped in.
Took a gamble and had the crank cut 0.75mm over size and rebuild the motor with a GE block from the previous limitation tests. Fought oil pressure issues from the initial start up. Couldn't get the oil pressure to rise after 3k RPM. Eventually resorting to Motul 300v competition ester based 10w60 helped significantly, but not enough.
The bearings deteriorated when engine speed was held in 7500 RPM range. That build was a torque monster. 504HP/588Tq on a Mustang 4 wheel roller dyno. Tuned by JeffTsai
I suspect the crank and/or oil pump being the issue as there are no other significant source that would cause low oil pressure. All parts were new except the head and 3.4L stroker crank.
Getting a motor built by JeffTsai @ Powerdynamix next with Stage 3 dimple porting on the head.
8.5CR due to limitation to pump gas. AEM Methanol kit with 50/50 mixture.
850cc Sard/Denso injectors / Walbro 450 pump
BC272 cams + BC valve springs + shimless buckets.

Tuned on Infinity 506
Motor will be shipped here to Taiwan and piece back together by summer.
The front bumper I have is a Mode Parfume with the grill/rails chopped off.
The side skirt and diffuser was something sourced locally.
The rear is a fusion of LS460 lower half.
The car won't go into paint until new motor is dropped in.
Couldn't wait on the interior so went ahead and installed the Clazzio seat covers.
Added the Blue 5D carbon fiber vinyl wrap and EL Wire light mood light strips.
Stereo is Phoenix Gold 600.2ti x 2 to Punch P3s 10".
Still on Airrex.
Only if video posting is available on here.
Stay tuned. I'll update again when I have time. May be another year, but better late than never.
