I am the original owner of a 1992 Caterham Super Sprint with 1700cc Crossflow engine, 5 speed transmnission and DeDion rear end, long cockpit version. It has been street driven and used in track days, more recently more track days than street travel, it has low mileage, around 12,000 miles last I looked.
I am just finishing a major rebuild and upgrade to the engine: 45mm Webers, roller rockers, bigger valves, A6 Cam, CP forged pistons (84mm, 11.5:1 CR), SCAT Crank, lightened flywheel, dry sump and Comp 4 to 1 header.
I have a couple questions now, maybe more later:
RE: Header The original header was the 'stock' 4 - 2 - 1 header exiting the body on the drivers side. My new header is the Caterham part Comp 4 - 1 header with the collector outside the body. My question, does anyone know how much to enlarge the hole in the body, does the hole center stay concentric or is it offset in any direction? With the engine installed (not currently) fitting the pipes one at a time may not be obvious and enlarging the hole an exact science. Any help here or a way to figure it out.
RE: Brake Pads The current pads are stock as delivered, any suggestions for a pad more suitable to track use? From what cars (make/model) did Caterham source the calipers from?
Thanks for all your help and suggestions
