These work for a 4g64, 4g63, g4cs and I think even the newer Evo/Eclipse 2.0s and 2.4s but they're not for the timing belt. I didn think about it but I do have a particularly ugly timing belt tensioning tool I made, so ugly it won't be showin its mug here, I assure you!

These are 1 driver and 1 installer used in a bottom end performance mod on the above engines. Here's a hint after I did this mod I blew off the oil filter a week later, caught it right when it happened, popped on another filter and 3-1/2 qts of oil and went on my way. 1 wk later I had the same thing happen at about 6500 rpm passin on the highway and wasn't so lucky
