RPM/Speed
Hi all. I bought an 87 RT4WD with a blown engine and since I love doing dumb shit, I'm putting a 3 cylinder kubota diesel engine in it. Hoping with some modifications and a garbage ebay turbo I'll be making a blistering 60-70 horsepower.
I've never actually driven a civic wagon, only honda I've ever owned was a 96 Del Sol.
Anyway.... what sort of RPM do these sit at for highway speeds? Say, 60-70mph, are they in the 3500-4000 range? This has the 6 speed manual and a D15a2 I think? Not even sure about the original engine. I hear some talk of being able to modify the transmission for a longer 5th gear, which might be necessary. My 2005 Pontiac Vibe does 75mph at about 2900 rpm, helped slightly by the fact that I've got larger than stock tires, which may also be a go-to strategy for the higher end speeds on the Civic.
