Aren't you seriously concerned about what else you will find post purchase?

 

 

i assume there is a vtec head on the swap and that the guy is not just trolling you by saying there is "vtec on a switch". yes there is a way to fix it, and that would be to properly wire the vtec pressure switch to the ecu. you can either get a wire harness that is already wired for vtec from the factory. or wire it yourself. all the info can be found here .:FFS TechNet:.

 

Learn early not to ignore bright red flags. He's selling his experimental project car, including all of his mistakes along the way. Don't buy Dr. Frankenstein's project car. You'll thank me later.

 

 

b20z, vtect switch. This is what I read in the OP



I've made it sound like vtec kicked in before with a high compression b20.......

 

I would walk away from that deal, OP. Halfass work done by incompetent idiots.

 

all of the above, plus.... if the ECU is not tuned to run in VTEC, and you force the head to engage the solenoid... what timing and fuel maps are going to be used and just how wrong will they be? (you can't see that damage from the outside)
It can be done, if the ECU can read the switch, any decent tuner can make the input toggle the maps.... but that level of tuner would never let someone have VTEC on a switch in the first place.
