jara Posted September 30, 2012 Report Share Posted September 30, 2012 Got a ke55, 4k, 3 speed auto. I know the auto is holding it back and I'm going to keep it that way, just wondering, is there anything i can do to give it a little extra punch? the hills really take it out of her.

altezzaclub Posted September 30, 2012 Report Share Posted September 30, 2012 Nope! We had an auto in the KE70 and that is exactly what happened. You can do the usual cam grind, Weber carb, extractors, sports exhaust, but the auto will still hold it back. Probably 1500cc 5K pistons will make up for it! Go manual- changing the box will take 30kg out of the car by itself! Quote Link to comment Share on other sites More sharing options...
jara Posted September 30, 2012 Author Report Share Posted September 30, 2012 the guy that did my head gasket said that it had racing sized pistons put in... i don't know why, he could be wrong. is the "cam grind, Weber carb, extractors, sports exhaust" going to make a big difference? sounds expensive too Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted September 30, 2012 Report Share Posted September 30, 2012 Yes it will make a big difference, and cost really depends on shopping around and doing the strip & assembly yourself. Cheapest would be the Weber 32/36 & adapter plate, 4-1 extractors and a 280deg cam cut. The cam is a couple of hundred bucks, as you get the followers ground as well to suit the new cam. The carb is for sale here and there on Rollaclub, the extractors occasionally come up but for under $300 you can get them new. Add a couple of hundred more for a sports exhaust system in 2" or inch & 3/4. You would have to pull your cam out & send it off to be cut, fit the new extractors & carb and hook it all up. It depends on how good your motor is right now, so when was the head gasket done?? What he probably means is that it is bored oversize, but it would pay to go back and ask him more details. Really its the ideal time to pull the motor out, and fix any small things wrong and check everything that is not wrong. Shim the oil pump, pop the head off and grind the valves, but don't take the pistons out. However if you've just had the valves ground and the head skimmed then leave the motor in and pull the cam out out through the radiator.

mhmills Posted September 30, 2012 Report Share Posted September 30, 2012 Go manual, you'll never regret it. Biggest power upgrade from the auto. Quote Link to comment Share on other sites More sharing options...
