Purchased an Full Race EFR 7163 kit in September 2018 only to do a compression test right after and get the following results: Cyl 1 190 Cyl 2 190 Cyl 3 165 Cyl 4 190 I was really looking to push the turbo so figured I'd go all out with a built motor. Purchased an SP63 Stage 2 off the shelf build a few months ago and I should be getting it any day now. Goal with the build is a car that can make big power on the street along with track days, while still spooling well enough to be competitive in Autocross. Goal is ~550whp. Parts I've ordered so far: FR EFR 7163 Kit SP63 Stage 2 Build South Bend S3 Enduro Clutch Kit Replacement Slave Cylinder SP63 6th Port Kit Aeromotive 325 LPH Fuel Pump (Figure with an unregulated fuel setup any extra flow will help with making my goal numbers on E50) Eric Yarbrough Wire Tuck w/ PI Dongle JBR Under-Route Hot Side Kit CS 3.5 Bar MAP CS Injector Seals JBR Oil Pan Baffle CS Intake Manifold (If it ever goes in stock again...) Koyorad 25mm Radiator - Already installed this, was a cake walk without a motor in the car. Some pics: Before anyone says anything... I am not rich, just run a side business solely to fund all car related activities. Having a monster MZR build has been a dream of mine since I was a kid in highschool nearly 10 years ago and joined the Mazdaspeedforums.
