What? Want Less Power?!

[MaximusPsychosis]

So kids, I have this lovely AE82 Seca, 4 speed auto and a well used, compression losing, oil chewing, 4AC. Now I was wondering about getting more fuel for the Ks then the Km/h... having all that power compared to the weak 2A from the old rolla, I got thinking, what if I leaned out the carby to the point the exhaust is coated white (and burning seals and rings and other things) for a little less power and more range...

 

on the other hand in the European and japan market, there is such thing as a CE80, or a CE90/96/97 that uses the C1 toyota Diesel motor (mmm, diesel AWD corolla ...ahem), that got me thinking, what if I find a townace or a liteace that had one and dropped it in? will you guys hate me?

 

Oor, I do remember seeing a thing called 4ACE motor, its a 4AC, with the Electronic Fuel Injection system (I am right, right?), it thats the case, is it possible to add a carby injection job (you know, them single injector in the throat of a gutted carby), will that be doable? because I could modify the computer to run lean...

 

Oh, I do have another 4AC lined up to buy, it has a 5 speed manual attached to it.. It is sitting in a sedan AE82, that found its way into a channel, front end got a little mangled, need a wee wheel alignment, its stuck doing a 85 degree turn..

 

PS, there is also the option of electric drive-train (or hybrid)... but think I'm in the wrong forums for That :P

Save yourself the trouble and get one of these http://en.wikipedia.org/wiki/Daihatsu_Charade . A mate used to thrash his and always get like 6l/km.

[MaximusPsychosis]

heh, by my calculations i'm getting 4.7L/100Km highway, 7.2L/100KM town, and I don't like the look of them things... I like the reach-back look, like the old KE55 coupes, and oddly, the ugly seca.

 

if I wanted 6L/100K I'd get my 1995 Camry running...

 

Alright, you got me, got no money, the best option I have is the carby lean-off, but I don't mind going though the scrap yard and playing silly bugger with odd parts om my car (hence the idea of the efi'ed carby)

 

now if I did come across a lite/townace in the yard, I'd see about the diesel swap.. even to an old wreck for a dummy fit'n'run..

[jono1986]

I'd stick with 4.7 and 7.2 mate, wish i was getting that.....

You want better fuel economy out of a 4a?

 

:lolcry:

 

You have an engine that chews oil so the bores will be oil washed, best to rebuild the engine or get a replacement engine that is good on compression and doesn't use oil or blow smoke.

 

If you get a replacement give it a service (oil and filters) and a fresh set of plugs.

 

What ever way you go, make sure the car is getting to operating temp as running them cold (faulty thermostat) will restrict vac advance and basically keep the choke on using more fuel, also run atleast 95 octane fuel, they love 98 but don't run it if you can't afford it but they do get a bit more out of it.

 

If you find it pings on 95 then back the timing down to 7-8 degrees.

 

EDIT: should get off facebook while I am making a post so it doesn't take 15 mins to do :laff:

Yeah, your right trev. it loves the oil when its cold.. I did replace the plugs just recently, surprisingly clean for old plugs, only one more fouled then the others (guessing the piston with oil-addiction problems). It has only done 2K and the oil looks like it needs another service (someone told me to use penrite, hmm)...

 

This old motor would of been in better nick if a couple of old men didn't fight over car repairs, now I have it :D done a manifold gasket, thee other one was burned to the crapper thanks to a few bolts loose, half the vacuum hoses are blocked up with solid carb, fuel is even getting in... oh and the thermo fan sensor is shot (must replace, the fan constantly running)...

 

I'll just wait till I get this wreck rebuild that motor and gearbox (maybe just a new clutch, see how rough it is), then I might rebuild this motor, or run it into the ground...

 

... on the other hand, could rebuild the 5S-FE and dump it in.. HA :lolcry:

I think you need to check your calculations. I'd expect 4.7L/100km out of a modern VW Golf turbo diesel not a clapped out 20-something year old automatic 4A-C. Double that figure and I'll start to believe it.

Ha, just read that, 690k's around town and 1000k's highway, must have long range tanks, would expect at the maximum (absolute max) 650k's highway and 500ish around town.

[MaximusPsychosis]

hmm.. maybe you're right Irokin, just done a quick calculation on my phone, 11.04L/100K, 255KM on 23L :/ sorry

 

still, according to the fueleconomy.gov (oooweeww)the camry does 9L/100k

.. same site says the seca should be doing the same :-?

 

ah well, I might go decarb this thing

..now where did I put that wd40 and hammer :-?

 

the old corolla I was pulling 750KM/tank(50L) combined driving..

ah those offical figures are always a bit unrealistic for people like us. Sounds like you could use a 7afe, they are tuned for power and torque very low revs and have no cam overlap, great for economy. Can someone who has owned a 7afe powered car verify this?

How are you going to measure mixture? Will you know if its lean or rich at whatever revs?

 

The modified 4K we run put in 7L/100km last week over 500km, and I'm quite particular about filling it up and checking the odo. That's with a cam, SUs, free-flow exhaust and bit of extra compression, on a trip at 100kph through the hills. Dead stock it did 6.5L/100km, but it was at half that speed! It managed 80kph comfortably and died on all the hills!

[MaximusPsychosis]

No real way of measuring it, only the tell tail signs of white muffler and hotter running motor (and maybe less power...) other then that, just old fashion trip/tank measurement..

 

of cause, i could be completely wrong about it...

1C not C1 but i'm just being picky.

I'm a fan of the diesels. But don't go expecting all the u-bute fuel economy that your seeing from the late model oil burners. Its all from being computer controlled, direct injection, common rail, turbo, etc etc.

 

Oor, I do remember seeing a thing called 4ACE motor, its a 4AC, with the Electronic Fuel Injection system (I am right, right?), it thats the case, is it possible to add a carby injection job (you know, them single injector in the throat of a gutted carby), will that be doable? because I could modify the computer to run lean...

Grab yourself one of those Weber carby adapter plates and go on the hunt for a CPI throttle body (Centre Point Injection), they come under a few other names as well, from the EA falcon (amongst others) and then grab a Megasquirt or if your willing to give it a go a Delco from the camira, pulsar, commodore, you'll just need the Kalmaker software.

You could look into hydrogen
