Love this build! I look forward to a final weight.
The F20C seems like the ultimate out-of-box n/a 4 banger. There was an MKI Ford Escort competing in Targa Newfoundland last year powered by an F20C running through a Qauife sequential gearbox. Unfortunately I had to help the driver out after he rolled it into a telephone poll on a practice stage, but he had it back up and running for competition stages. I would have done horrible things to have that drivetrain setup.
Yes, I too think it might be the best N/A 4cyl out of the box. I do think just from the inntial reactions from people outside this community that it is a little frowned upon to be putting 4cyl where 6cyl belongs and a Honda engine instead of a Nissan/Datsun, but I guess it is different and for me this project is all about the driveability and fun factor and you just cant beat that butter-smooth 6 speed and 9K redline when it comes to the F20C.
