What kind of ignition coil does a Honda S2000 use?
The OEM s2000 ignition coils are a hit or miss on what kind of power they can support. We have seen the OEM coils support very high power levels (800 whp+), but also have issues even with decreasing spark plug gap greatly at 400 whp power level. We have found the best replacement for the OEM s2000s are from 06+ Civic Si / K20 coils.
What should the plug gap be on a Honda S2000?
Plug gap should be between 0.018~0.028″ depending on the condition of the ignition coils. If using E85, race gas, or pushing pump gas to the limit NGK Iridium BKR9EIX plugs are what we recommend. The OEM s2000 ignition coils are a hit or miss on what kind of power they can support.
What should I do if my Honda Civic cylinder is misfiring?
Check the cap for any cracks, verify the pick-up coil is a safe distance from the shaft, and check the ohm readings on the ignition coil. If all are within spec try changing the spark plugs first, and then proceed to move up to the wires as well as the distributor. Figure 1. Checking the ignition coil.
Why does my Honda S2000 not have FRM liner?
00-03′ s2000s can suffer from oil jet banjo bolts that do not flow adequate amounts of oil to the cylinder walls. The FRM liner on the s2000 cylinder block walls needs to have a constant oil supply in order to prevent scuffing of the piston. The banjo bolt/oil squirters provide this.
