ke20rolla Posted February 3, 2008 Report Posted February 3, 2008 Hi everyone just want to know what HI CAM means when it comes to the ke70 corolla. Must have something to do with the camshaft in the motor, surely :jamie: Please can anyone cure my curiosity? :hmm: Thanks. Quote
JiP Posted February 3, 2008 Report Posted February 3, 2008 I thought we were saying Hi to Cameron :jamie: Quote
untubbed_20 Posted February 3, 2008 Report Posted February 3, 2008 I always thought they put a slighlty larger camshaft in the 4k for that model onwards and it made a bit more power ,I could be complety wrong though Quote
LittleRedSpirit Posted February 3, 2008 Report Posted February 3, 2008 Gotta Love Beallys sense of humour... Quote
irokin Posted February 3, 2008 Report Posted February 3, 2008 I always thought they put a slighlty larger camshaft in the 4k for that modelonwards and it made a bit more power ,I could be complety wrong though Nope absolutely nothing different. 100% marketing bullshit... worked too. Quote
Trev Posted February 3, 2008 Report Posted February 3, 2008 It was to stop the rabbits getting in... Nah take your tappet cover off, They put a spare cam under there. Quote

camerondownunder88 Posted February 4, 2008 Report Posted February 4, 2008 HAHA I though this thread was also saying Hi to me..LOL Anyway I read a book once on designing piston motors etc few hundred pages long. It mentioned a motor that has its cam on the side of the motor (like a K motor) is termed a Hi cam motor. don't know how true it is but hey the book had it. And I just put it down to yes was the same motor so Toyota used the technical name for a old motor to help try to sell it that is it. Also KE70 4K cam shaft is 100% same as other 4K ones. Only K motors that get slightly different cams are K-B motors usually had different cams in sprinters and van motor versions. That is why when you run an electronic dizzy on a sedan cam it just isnt right. Get the dizzy re graphed and WHAM you get more power and that. Cameron Quote
Rolla__Boy Posted February 4, 2008 Report Posted February 4, 2008 I thought it had a slightly different profile, so it could run unleaded fuel more efficiently. They came out at the same time.I just put one into my ke55 over the weekend and it runs much better than the old non hi cam k motor did (I have have this car before unleaded became the norm). I am using the same carby,inlet and exhaust manifold. Probably got less K's than your old engine...or has just been looked after better. Hi-Cams had different water pumps though Quote
ae174agze Posted February 4, 2008 Report Posted February 4, 2008 so toyota bullshited people in jazzing up the old tyerd 4k by make the new and owww new totally awsorm 4k high cam ahahahah way of marketing Quote

Rolla__Boy Posted February 4, 2008 Report Posted February 4, 2008 Well they have a different part listing...and are supposedly different. Maybe one of the engines wasn't actually a hi-cam one? Quote
Taz_Rx Posted February 4, 2008 Report Posted February 4, 2008 There's heaps of different outlet/inlets on the water pumps and thermostat housing as most would know. The bolt pattern for were they bolt to the block is all the same. Only difference with the ke70 water pumps is the mounting for the pully. A ke30/55 etc pully won't fit the ke70 pump and vice versa. ;) Quote
