Mr Hardware Posted March 31, 2005 Report Share Posted March 31, 2005 Hi All I have a 1980 KE55 Sedan with a stocko 4K-C in front of a stocko 5 speed. She drinks too much for my liking. 400km will be 48L or so, and it doesn't really change much whether I have a bad case of lead-foot-itis, or i granny drive her. Thats city driving though. She comes down to about 40L for 400km of highway. I have changed oil, oil filter, air filter and spark plugs. I use normal Unleaded and FlashLube fuel treatment. She's got plenty of power. I don't need any more power. What are some ways I can make her drink less without losing power, and without costing the earth? Quote Link to comment Share on other sites More sharing options...
crazy_bunny Posted March 31, 2005 Report Share Posted March 31, 2005 that really isnt that bad on fuel, most small cars nowdays are only geting 500 - 600 ks on a tank... older carby style 450ks is normal.... but yeah u could change the air/fuel ratio... but meh there goes engine life Quote Link to comment Share on other sites More sharing options...
Mr Hardware Posted March 31, 2005 Author Report Share Posted March 31, 2005 Yeah, i don't feel like killing her to save a few bucks. I know the fuel economy ain't too bad, but after driving Nana's new Toyota Echo Automatic, and having 300km cost me $18 in her, i just wanted one. The only other place you get that kind of saving is LPG. How do you tune a 4K-C? What numbers do i need? Quote Link to comment Share on other sites More sharing options...
Mr Hardware Posted March 31, 2005 Author Report Share Posted March 31, 2005 Vaccuum Guage Install - Cheap Get the Carby rebuilt and rejetted if necessary - Cheap These should get you well on your way to fuel savings My grandad has a Vacuum guage in his VH Dunnydore. Does it tell you fuel economy? How much is cheap? And how much is cheap for a carby rebuild? Quote Link to comment Share on other sites More sharing options...
Mr Hardware Posted March 31, 2005 Author Report Share Posted March 31, 2005 No mods whatsoever. I am a computer technician. I have no real Idea about cars. I know how to change oil, oil filter, spark plugs, spark plug leads, battery, air filter, coolant but thats about it. I would not be game to rip off my carby. If i could get 450km from 40L I would be over the moon. I don't even get that on the highway. Quote Link to comment Share on other sites More sharing options...
demuire Posted March 31, 2005 Report Share Posted March 31, 2005 I used to get about 400ish k's from a tank in my stock KE55... Quote Link to comment Share on other sites More sharing options...

demuire Posted March 31, 2005 Report Share Posted March 31, 2005 (edited) Well, my Camry (3SFE, 2L) does just under 600km of mostly highway driving, on a tank of approx 55L. It does about 500-550ish km of city driving on the same tank. Towing a trailer, I got less than 300km on the same tank. Mostly because I had to rev each gear out a fair bit, and even doing 90km on the highway I had to sit in 4th gear, unless I was going downhill. On the steeper hills it was back to 3rd... My Corolla (4AGE), I have no idea because I've never run the tank much below 1/4... Edited March 31, 2005 by demuire Quote Link to comment Share on other sites More sharing options...
Medicine_Man Posted March 31, 2005 Report Share Posted March 31, 2005 I get 400-450km out of a tank of petrol in my KE70, most of my driving is highway driving, though I'm never easy on the throttle, always giving it lots of stick. I recon I could still get about another 50-100kms out of the tank if I was game enough to run the car from the empty mark down.. Quote Link to comment Share on other sites More sharing options...
demuire Posted March 31, 2005 Report Share Posted March 31, 2005 (edited) My 4AGE tends to run pretty rich. Especially up past about 6000RPM. And Hal has 50L I think. Maybe even 55. In fact, I think the Camry might actually be 60L, not 55L... Edited March 31, 2005 by demuire Quote Link to comment Share on other sites More sharing options...
irokin Posted March 31, 2005 Report Share Posted March 31, 2005 I get 8.3L/100km :D I have extractors with heat wrap, a weber 32DGV, 1.6L 2T. I think the heat wrap is helping heaps. Quote Link to comment Share on other sites More sharing options...
kangaroosa Posted March 31, 2005 Report Share Posted March 31, 2005 I get 10km/L around town. Thats with a worked 5k and a single DGV weber. Thats NOT driving like a grandma either. I reckon thats pretty acceptable! Quote Link to comment Share on other sites More sharing options...
TRD ke70 Posted March 31, 2005 Report Share Posted March 31, 2005 i'd check the exhaust just to make sure you haven't got a blocked muffler, i know adding electronic ignition helps, they start easier and are i little more fuel friendly. i had a camry at use to do 550km to a tank around twon and almost 650 on the hi way, trying to remenber why i sold it.

Super Jamie Posted April 1, 2005 Report Share Posted April 1, 2005 no, that is about right economy for a stock 4k in a 55. emissions gear and heavy weight suck, yo Quote Link to comment Share on other sites More sharing options...
irokin Posted April 2, 2005 Report Share Posted April 2, 2005 Anyone interested in doing a coil pack conversion on a K motor :dance: Ive got some CA18 parts that would work beeautifully. Ive seen the CA18 CAS (crank angle sensor) grafted onto a datsun distrubutor before...but I can't find the pics of it anymore :D Quote Link to comment Share on other sites More sharing options...
