Old original clutch burnt out ready to install the new spec stage 2+
New 7.5" intercooler
Hand for comparison
One of the many times the transmission has been out. That time was denial the motor was rod knocking and I was hoping it was just loose flywheel bolts
After 50k miles on the spec clutch, still looking good.
Finally bighting the bullet and hoping the bearing didn't take out the crankshaft. It didn't!
First set of many spun rod bearings.
One random maintenance day with the original motor
Front clip removed to pull the tired original engine out.
Pulling commences

Build story

Bought the car May 2017 bone stock with 130k miles and 6 previous owners and have slowly been building/repairing and driving it ever since. Built the car completely backwards with the first mod being the single turbo kit in May 2018 after bringing most of the common maintenance items up to date followed by the first fuel pump upgrade in Oct 2018, clutch in Nov and finally got rid of the stock intercooler in Mar 2019. Drove the car in that configuration for years. Spun my first set of rod bearings in Oct 2019 at 194k and swapped them out on jackstands in my driveway and continued driving the car until I spun my second set on the same motor at 223k. The original engine was still running strong but was drinking a qt of oil every fill-up so I decided to swap in a "refreshed"(rod bearings and resealed) 120k mile motor at 231k chassis miles. I decided I wanted more power so I went with additional port injection with a flex fuel sensor to run e85 at the time of the motor swap. Chassis is now sitting at 247k miles and I drive it every day.
