Vtec installation

The last thing you want to do is drop a valve at high RPM. Apply to the VTEC lobes, journals and the cams themselves. The cam caps should already be identified and laid in place. If you are buying a used VTEC head, make sure to ask for the right cam caps and the proper orientation. Using a different set of cam caps is asking for trouble. Because each cylinder head is different, picking up a used set of cam caps may lead to engine failure or premature damage.

In many cases a line hone is required which makes using different cam caps completely cost inefficient. The caps are labeled I or E for intake and exhaust, and should be numbered 1 for cylinder 1 to 5 from the timing side of the engine to the distributor side, respectively. Make sure that all of your temperature sensors are properly teflon taped and installed. The dummy sensor is a one pin connector, where as the temp sensor is a two pin unit that your Honda ECU uses.

Wiring up the VTEC pressure switch and the solenoid is simple to do. Check the torque specifications at the bottom of our LS VTEC build page to see what you should be torquing the sensors to. Because this leg will hit the VTEC solenoid, and only one bolt will truly line up. Once you have your LS VTEC build assembled, make sure to use the proper break in techniques to ensure a long life and proper ring seating. Leave them for us below and let us know!

Need to know what are my options are for SMOG. Hi Musa, BAR legal Honda engine swaps are definitely pretty easy to do, and it really depends on your ref. My recommendation is to try looking for a friendly ref in your area that may be more lenient than others. Take your P75 ECU in and speak to the ref about what might be wrong with your swap if he turns you down. This site uses Akismet to reduce spam.

Some ECUs have these parts already. In the past we used to include a 10k resistor for spot R, but we never found one ECU without it, so we stopped including them. If you find an ECU with a blank R spot, please contact us.

In spot IC14, solder in this part. Install them correctly. Use a leftover piece of a resistor or from the diode legs to jumper this spot.
