If I add a turbo kit to my 1993 Honda Civic del Slow Si (manual), what other modifications would I need to make?
Since the car has 145K and no resale
value, all I want is to keep it and get
a little more pep out of it.
A turbo will put a lot of stress on an engine- the factory makes beefed up engines to handle the extra power- how many engines have been blown because owners thought that it would be easy to just "add a turbo"? Also, you are wrong that the Del Sol has no resale value- unless it is wrecked, these are very popular little cars-
I guess with your turbo mod you have a pop-off valve / waste gate? A large size front mounted intercooler will help, & a 62 mm or bigger throttle body, & MSN ignition. Save all your engine parts to re-build it someday to phase II. New bearings, rings, pistons, cam, & ported & polished cylindar head with new matched for the cam (kit) valve springs & valve guides. With 145k miles, it won't last too much longer. Seek a pro Honda machine shop to do the work & assemble the short block. & or start to build-up your spare (salvage yard) motor now, then easy for you to switch them out when the time comes.
