Stumbled across this site trying to find information on my N75 boost solenoid. It takes a little patience (because it's bilingual) to look through and find stuff, but there is quite a bit of info there. I found a bunch of pdfs for my engine by looking at engine page.

I looked at the

Mitchell Repair Information Company which cost money to subscribe to.
