So damn close. We've been working with the motor for a couple of days and mostly chasing down a few electrical gremlins. Namely for some reason the ECU wasn't triggering the injectors as both sides in were getting 12V from the main. So we softwired the injectors to the ecu and now the injectors are working properly. I have to recheck that the coils are actually on the right plug, but all in all it looks like startup will be tomorrow night.

 

Thanks!

It's running the Link G3 Plus. Overall the ecu seems to be a keeper. We had some trouble at first with the ignition but after some calls to nzefi, we found out that we had to change out the firing order in the ecu. Once that was figured out, the car fired right up and idled smoothly. It was a bit like training a dog. The dog wants to do what you ask, but it doens't know what youre' talking about. Same thing with the motor. It wanted to run the whole time, but just didn't understand what the ecu was telling it. :) In the video, it's the second idle attempt. Much of that is due to the tuner, I couldn't ask for any better than Darin.

 

Thanks Chris!

Thanks Ed, fell free to call anytime. Also I have some news about the compression ratio. It so far seems to be normal. :) Whatever it is, it's definitely NOT 14:1. With the piston mixup, it was always a craps shoot as to ratio, but so far every cylinder is in the 170psi range. Perfect for boost :) I have to say I'm happy about that. I suppose we clearanced enough out of the heads, and the dished valves helped out a little. There also may be some cam overlap. Either way, we've go the green light for boost.

 

Thanks!
