Installed Toda valvetrain/cams --- need advice please
Hi all,
If you could help me out with some questions that would be much appreciated!
Quick summary:
Shop installed Toda B's plus Toda springs, retainers, cam gears, timing belt, Spoon rocker arms.
Didn't remove the head (used compressed air to hold up the valves, which are stock), has a stock head gasket therefore stock compression. Motor is a '98 spec B18C ITR motor. Stock bottom end.
ECU is a OB2A JDM ITR ECU with a 'Toda program'. (not too sure about the A/F yet, but there's not knocking or pinging). Car is running butter smooth after the install.
Questions i have:
1. The motor generates a LOT more heat now after the cam package install. Any ideas why?
2. Any recommended cam gear settings? (note, i have yet to measure valve to valve clearance, but i'm thinking i'm safe with about 3 degrees between the intake and exhaust going either way? ie: intake +3 exhaust 0 / intake +2 exhaust -1 / etc..) i hope to measure valve to valve when i do my rings in the near future.
3. Related to question 2; quite the lack of power below 3000rpm...normal? or will cam gear tuning therefore, dyno tuning will fix it?
Keep in mind, motor is a JDM ITR with boltons (I/H/E) and a stock bottom end.
Any advice from the all motor gurus would be much appreciated. Thanks and sorry if i'm asking dumb questions!

yup, definitely something i will need to do..but i think i should get the valve to valve clearance measured out first...
along with a wideband, i'll be running the AEM EMS on this set up as well.
