Nd4SpdSe - 1992 Mazda Mx-3 GSR (End Of File)
Posted: January 14th, 2006, 2:23 pm
I've got a few small projects lined up for this year, and I'll document them all, but the goal for 2006 is to get the Mx-3 at least in the 14's, and get rid of my dreaded wheelhop. The engine *is* a KLZE, not a KLDE.
For the engine, these are all the signs that I've come up with in research and talking to other people:
- Sludge on the underside of the valve cover indicates poor maintenance.
- Ticking lifters since it was first installed, usually a sign of high-milleage.
- Dyno from October 2005:
Max Power: 147.97hp @ about 5600rpms
Max Torque: 148.50ft-lbs tq @ about 4700rpms
- Compresson test from October 2005
180 185 170
185 160 180
Ideal seems to be somewhere in the high-190 to low 200 mark
- 1/4 Mile Trag times are a stead 15.4 - 15.4 seconds
- The best drag race was done after the engine and clutch break in period, was 14.756sec @ 91.51Mph. Even though it was in the 14's, apparently the low trap time indicates lowish peak horsepower. The stock intake and exaust setup I assume created more torque. Adding my bolt-on mods for better top end horsepower may have removed the benefits of the stock system which created more low end torque, which compensated for the lower power, and gave my car a quicker 1/4 mile time.
Engine and mods:
- Millenia KLZE with KL01 Cams
- Curved-neck Intake Manifold
- PRM Cold-Air Intake
- KL36 ECU and JE50 VAF
- New 02 Sensors
- OBX 1gen Headers
- Magnaflo Hi-Flow Catalytic Converter
- Magnaflo Muffler
- 2.5" Stainless Crush-Bent Exhaust
- Walbro 255LPH Fuel Pump
- New Plugs (NGK Irridiums for Probe 2.0 i4)
- Injector flush few weeks prior to dyno test
