Hey guys.
I recently purchased a ke55 completely stock and now I’m looking to do a few upgrades. It’s a 3 speed Auto, so i guess my first question is what type of manual gear box I could fit and how much it would cost (would need a mech to do the work). Other than going manual, what other recommendations would you suggest for increasing power/efficiency. Lastly, driving on the highway for no longer then 10 minutes and the engine went red hot. I pulled over and the radiator reservoir was bubbling. Not sure yet if it’s a thermostat issue or if the old ke isn’t supposed to run at over 90/kph, regardless, I need the car to be able to handle highway use.
I appreciate any suggestions, cheers.
