ketowagz Posted November 9, 2012 Report Share Posted November 9, 2012 Hey guys. i'm looking to re join the corolla owners community :thumbsup: only having owned a 4age powered ke70 my knowledge of 4k and 4ac motors are very very limited. I was just wondering does anyone know ways of pushing out more power from these motors with out weird draw through carby turbo setups? (can't drive turbos due to S.A laws :() obviously i'm not expecting to bolt on a better carby and get an extra 1000 rwkw. but anything that would make the car have a bit more power and torque. if you could help in anyway by telling me what mods i could do. where to buy these parts from and how much money i'm looking at spending for these parts etc. as much help as possible would be awesome because as i said i'm a 4k and 4ac virgin and know nothing about these motors all i do know is that i won't be going very fast lol. cheers in advance Clouds Quote Link to comment Share on other sites More sharing options...

altezzaclub Posted November 9, 2012 Report Share Posted November 9, 2012 Cost me $2000 for twin carbs, custom cold-airbox, Crow cam, extractors and full exhaust system. Had the head done & fitted new bearings but never touched the pistons. Next time I'll bore it out to take 5K pistons and run a 1500cc 4K. It goes up hills fine, cruises at 100kph and last week it did the 650km from Walcha to Orange at 6.3L/100km, although it usually uses 7. Although not hard to mod, I'm afraid the 4K will never match a 4AGE! http://www.rollaclub.com/board/topic/42407-the-girls-ke70/ Quote Link to comment Share on other sites More sharing options...
