Stock sleeve D16Z6, stock head, SC34, RC440
Car originally had a set of 660cc modified IPT/Honda injectors that were causing glitches at idle and fogging the plugs due to poor atomisation. We threw some RC440's laying around in to get the guy rolling until his replacement RC750 arrive. I'm guessing the cam gear is a hair off resulting in solid midrange power without much of an increase in the higher rpms, typical D-series parts mishmash. I'll retime it before I tune on the new injectors later this week. 11 psi wastegate: 14 psi: 19 psi: Car's neat as a pin, I'll make sure to get copies of it's pictures before updating.

Got a set of RC750 for the car and retarded the cam timing 3 degrees. Graphs certainly look healthier! Kinda surprised me as the engine reputedly hasn't been decked/milled any significant amount. Maybe the aftermarket cam gear isn't terribly precise? 240 whp at 12 psi: ~14.5 psi: 18 psi: 20-21 psi:

It really takes a second to catch on with the D16... low mileage stock block that was barely milled or decked during the build translates into the the engine is 2-4 degrees out of time. Every D-series needs a cam gear, and to be put into correct time, before the tune starts.

What's the easiest way to put it in correct time? Do the math based on how much the setup has been decked/milled, or something out?Joey Misanthropy wrote:It really takes a second to catch on with the D16... low mileage stock block that was barely milled or decked during the build translates into the the engine is 2-4 degrees out of time.

Center non-Y8 distributors, lock timing at 16 degrees, adjust cam gear until in ignition timing. Y8, IMO, need the Belben degreeing kit until I've been through one and can figure out a way to eyeball distributor alignment.
