Last week, I was surprised to find out the dieseling sound in my Mach was caused by 4 spun rod bearings. The surprise really wasn't the spun bearings, but that 4 spun bearings didn't make a lot more noise - I only heard a low dieseling noise very briefly at start up, and when driving about 2200-2300 RPMs. Anyway, I’m definitely into a motor rebuild.
I have decided that I am not adding a supercharger or a turbo, and I do not want to get into upgrading the fuel system. But, I am going to build the new bottom end strong enough to handle anything I throw at it in the future.
I’m still trying to decide how much power to shoot for, but since my Mach1 is more of a daily driver and an occassional road course car, I know I'm looking for the low end torque instead of a peak HP number. After talking/PMing/emailing several people, this is where I am heading...
Block:
- Forged Rods with ARP2000 Bolts
- 020 over Forged Pistons 10:1 Compression
- Oil Pump with Billet Gears
- Fluid Damper
- Windage Tray with ARP main studs
- Aluminum Flywheel
- Clutch and Pressure Plate
- Stock Intake
Heads:
- Valve grind and deck heads
- Bronze Valve Guides
- Custom Cams (specs TBD)
- Oversized Valves
- Valve Seals
- Valve Springs
- Adjustable Cam Sprockets to degree the cams
- ARP Bolts
- Probably some long tube headers
I am going to keep the Zex 100 shot, the 3.90:1 gears and the Borla Stinger Cat Back. The MRT Catted H-Pipe will probably need some modification to fit with the headers.
I have a local engine builder all ready to go. And the head work will likely be done by John at Modular Performance.
So, what am I missing?????
