My eclipse gsx with 272 cams
A short clip of my eclipse idling and a couple revs to 2k and 4k rpms. Open downpipe at the time, now I've got a turbo-back Exhaust.

4G63 Lifter installation without special tool part 2
In this segment I reinstall the rockers over the new lifters. Again, no special tools, or removal of the timing belt, cams, or cam caps. All we are doing here is putting the rockers back in place over fully bled aftermarket (topline) "3g" big hole lifters. These are NOT ebay lifters. I can't speak for them - I have never used them. *** Some side notes and related info*** -This car was purchased used with about 22k on it. They started ticking heavily about the third day after I bought it 2 years ago... and have ticked for about 20k more miles. -I recently switched from a 969400011 rom (05 rom) to a patched version of 96530006. Which must run different knock filters, as I had excessive part throttle knock I previously did not have. -Topline lifters stopped the part throttle knock -While they were pumping up and chattering, I couldn't even drive the car. I got repeated high knock counts to the point I could feel timing being pulled through the floor. -Once they filled up with oil and went silent I have NO knock. Even between gears, from stops, after a aggressive throttle then reapplication of throttle... Basically all the places I had knock before, I don't now. Which is great when it's this simple. Yay for lifters that don't tick.

4g63 Coil On Plug 201
This is a continuation from my earlier coil-on-plug how-to video. I was troubleshooting an ignition problem where I couldn't Boost over 14 PSI without misfiring or backfiring despite having an ignition amplifier, and this is what worked to completely resolve my troubles. There's lots of information about what parts work well on a 4g63 (and their relevance) as well as lots of reports about people having ignition problems once they're installed. I noticed that there's not really any instruction available regarding ideal methods for trimming the longer Chrysler boot down to the size and shape for a 4g63 setup. Some of this could be due to the depth of various COP mounting plates, but this video is intended as an effort to help fill that void regardless of why. If the boots are not trimmed properly, then as combustion chamber pressure increases, the possibility of the spark arcing from the plug into the plug well is possible. This can happen on improperly insulated plugs, or as a result of an old worn boot. The solution if your coil resistance is good... is to run down to NAPA and buy yourself a set of new boots. They come with new springs. They just need to fully-sleeve the spark plug's ceramic insulator, and make good electrical contact internally. If air can get in and out, so can spark. FYI: When inspecting older worn-out boots, wherever spark leaks through leaves a white spot.
