GM Top Engine Cleaner part#1052626 (available from your local GM dealer) for de-carbonizing the engine. HOW-TO with Seafoam. You can use either product for de-carbonizing...I prefer GM Top Engine Cleaner as it is O2 sensor safe. I use a different method of application. I remove the intake tube and spray in the cleaner with THIS.

I have been unable to find the lift/duration of the VX camshaft. I thought I saw it on gassavers once.... Do you know this information and could you link it if you find it on gassavers?

[GasSavers_TomO]

I did some searching and couldn't come up with anything on the VX cam specs. I'll look further into it and get to posting the info I find.

Do you know what the difference is in the 92 - 93 ECU, & the 94 - 95 ECU?

I find 2 different part numbers for 49 state models at San Leandro Honda. Are they interchangeable, or do you need to use the correct one for your model year?

[GasSavers_TomO]

It looks like the 92-93 uses the original revision of the ECu and the 94-95 used the the first revision.

I have tested one of the original revisions in my VX and it works fine. I have it for sale too if you need a replacement ECU.

From the Haynes for 96-00 I know these specs for the VTEC-E camshaft in the Civic HX (D16y5):
Lobe height:
Intake:
primary------1.5129 inches
secondary---1.2674 inches
Exhaust-------1.5269 inches

I was unable to find duration/lift values.
I have an HX and would like to install a VX camshaft. I have one already, but it is in Tulsa in storage so I need to know if this is worth pursuing.
Do you have a Haynes or Chiltons that would give the lobe height for rebuild?
Thanks.
