The Project:
1988 Toyota Supra Turbo. 57 trim CT26 from MDCMotorsports. 16psi.
Lost ~40 psi compression on #3, #5, #6 cylinders, on 212k mile 7MGTE.
Current Status:
Engine:
Crankshaft: 7M, Stock, will be re-machined and upgraded.
Crank Scraper: Once the shortblock is assembled, custom crank scraper will be made @ Ishihara-Johnson.
Connecting Rods: Eagle Forged Rods with 3/8" ARP2000 Bolts
Pistons: Wiseco 83.5mm Forged, with 1.0/1.2/2.8 rings.
(Entire rotating assembly to be lightened, and zero balanced)
Bearings: Genuine Clevite 77 P series throughout
Block: Will be bored with a torque plate, mains trued and honed.
Harmonic Damper: ATI harmonic damper for the 7M.
Flywheel: 12lbs Chromoly lightweight Ebay flywheel.
Transmission/Driveline:
Currently a worn out, slipping A340e. Replacing with a rebuilt (by me) manual transmission:
R154, new design synchros, new bearings, new seals. New Marlin Crawler HD bearing retainer. New Marlin Crawler nylon seats + shifter bushing.
Stock r154 drivetrain, unless budget allows for a one piece aluminum driveshaft.
Turbo/Exhaust:
57 trim CT26, unclipped, from Jon @ MDCMotorsports. Will break in on stock boost, and move back toward 16psi.
3" Divorced Downpipe, recirculated, with flex section. 3" mandrel bent exhaust, no catalytic convertor. Magnaflow 3" in, dual 2.5" out stainless steel straight through muffler.
Fuel System:
Currently stock injectors and pressure regulator. Walbro 255 already installed, with drilled J-tube. Once break in is complete, moving to Denso 550s + Aeromotive AFPR.
Engine Management:
Stock TCCS + MAFT-Pro. Currently running Speed Density with no AFM in the system. Zetronix ZT-2 keeps tabs on my AFRs. Will be adding an EGT probe as soon as time permits.
Pics as this comes together. :naughty:
