85' Buick Park Ave One of 5,759 Olds Diesel powered 4 door cars. There were only 536 Olds Diesel powered two door cars. Exterior is in need of repaint (peeling clear coat). Interior is mostly stock with an after market CD, AM/FM reciever, digital oil pressure, water temp. and boost pressure gauges.

The factory engine for this car is the 4.3L Olds Diesel Vin "T" (no it was not turbocharged from the factory). This 4.3L Diesel (engine shown is currently being replaced with a "currently in progress" rebuild) has been upgraded with a T3-T4 hybred turbo, American Cams roller turbo diesel cam/roller lifters and a very large K&N air filter (hidden inside left front fender).

Block has been bored .040" over for the new pistons. I've opened up all the oil drain back holes to accommodate the extra oil draining from the turbo. More pictures to be added as the assembly progresses.

Crank and bearings, roller cam and bearings, injector pump drive and bearings and single roller timing chain and gears are installed.

Pistons (22.5:1 Compression Ratio) are fitted with .040" over Total Seal piston rings. Rods resized, new pin bushings, and assembly balanced.

Pistons and rods installed in block with rod bearings, ARP rod bolts and torqued to specifications.

Shortblock is assembled ready for smaller parts, oil pump, pan, core plugs, timing cover, etc.

Cylinder heads had cracks welded and machined. New guilds, valve seats, hardened keepers, and Ferrea larger diameter intake and exhaust valves were installed. Intake and exhaust ports have been opened up "slightly".

Valve train consists of Harland Sharp adjustable full roller rockers, 7/16" rocker studs, hardened pushrods, and hardened guild plates.

Custom Garrett T3/T4 Turbo by Turbos Direct, LLC (Compressor A/R .60 and Turbine A/R .48). Custom fabricated waste gate actuator arm. Compressor outlet is clocked at different angle than in earlier pictures to accommodate the addition of an intercooler.

CXRacing intercooler and piping will be installed in front of A/C condenser and plumbed into turbo and intake manifold. Will not be using the diesel truck intercooler - to great of a pressure loss. Pictures will be available soon.
