Is this for real, does anyone on here own this? If so please do a write up or maybe there is an existing thread? http://cgi.ebay.com.au/Toyota-Corolla-1984-KE70-100kw-4wd-rally-car-rollcage-/250717095175?pt=AU_Cars&hash=item3a5fe74507 That would be so fun

Click Me hmmm, a stock, 4x4 liteace, running a 3Y... id be intrested to know what driveline accessores its running... :jamie:

Gday, I have a 1975 2 door ke30, it has a 3k-h and had a k40 which I only just swapped over for a k50, now this gearbox has made my speedo out. Any suggestions on the best way to solve this problem as its turning over quicker and will be racking up more k's then what I am really doing. Any help is appreciated cheers.

howdy just after some advice on the best 5 speed gearbox to put in my ke30.. which one is the best and easiest conversion?

Hey folks, I tried searching for this but it wouldn't let me search "5" or "6" because they are too small...anyhow, if this has been asked before please just redirect me and it would be greatly appreciated :thumbsup: So basically, I'm converting my 4afe ae92 to a blacktop and i was wondering whether i should purchase the one with a 5 speed tranny or the 6 speed? There will be none to minimal trackwork being done and it is a daily. So straight line speed which is quicker? Or more economical? And as a final question, would the 6 speed need modifications done to the transmission tunnel/shifter, and how much would this cost? As there is an extra gear and all... Any person…

does anyone know if there is another car or anything i could use to change the 4 stud pattern to a 5 stud pattern? the mags selection for 4 studs is crap and the mags i want only come in 5 stud!! thanks! Dale

ok gust this is the second time it has happend to me with too difrent type of gauges (split fire) sold (auto meter) new 1 ok i hooked them up as the instructions sed to do // but wen u set your shift light posistin lets say 5000rpm the shift light would flash at 4000rpm but not stay on it would just flicker then wen u hit 5000rpm it would flash and stay on as ment to. just wondering if anny of u guys have had this problem or anny one have a taco and dusent have this problem with your gauges ???

Where can you purchase solid lifters for the 5k engine? Does the engine ever come out with standard fuel injection??? I have heard that few 5k engine actually have solid lifters stock, not the hydrolic lifters! Is this true? If so, How can you tell??? ( I'm new to this stuff ) :D thanks to All. ROLLAS 4EVA

Hey guys! I got thinking on the weekend, with my 5k, I could either bolt on a draw through system turbo or bolt on the supercharger! What do you guys think? Any comments would be great! I had a look at a supercharger to buy as well, $300 for an average intercooler and a sc14 (off a Toyota chaser 1ggze ) what is the correct supercharger for this application? Any thoughts or comments would be appreciated!

hi guy wanting to buil a 5k and seeing as there is much avalibil in cams 4 a 5k, can u use a bigger cam for a 4k in a 5k? i saw that the timing chain part numbers are the same between 4k-5k only diff i can see is soild lifters in 4k and hydrolic in 5k any help would be good

Hi all, I currently have a 3K in my KE10, but have a 5K on the way. Can I use the 3K rocker cover on the 5K?? I want to do this because the 3K rocker cover has the old Toyota symbol on it, where as the 5K is blank. Cheers, Ken Edit: Also, the 5K is coming with a 3Spd Auto from a Ke50-70 (not entirely sure what model), will I have to modify the tunnel??

I have a 5k rebuilt with 20 over piston and cam grind of 262 in my kp36 pick up daily driver. Those are the only modifications to the engine. the exhaust is two inches from manifold back. Thinking of getting a 32/36 Weber, the question; with this set up is it necessary to put on extractors? I currently have stock intake and exhaust manifold and carby off a 3k. I know that generally cam, carby and extractors go together. I live in Central America and getting extractors is not very easy. Any input.... Thanks

OK lads, After fussing with my old and crusty Aisan for nearly a week, I threw in the towel after realizing gas was leaking out the main shafts. A few days later, and I have a nice and shiny Chinese copy sitting on the wife's kitchen table. Ahh, but it looks like some changes occurred in the design. - Top cover of new carb had the fuel inlet clocked 90 degrees the wrong way, and a different thread size for the central air inlet stem bolt. To save aggravation, I just swapped in my old top cover (painted black because ugly). - Circled in green here looks to be a bimetallic switch which is controlling vacuum by some preset temperature. This fe…

I have a 5k motor with a head that has Electrolysis around the head gaskit, and pistons that are oval (just a little amount of piston slap). would I need to hone the bore back to a useable shape OR bore to the bigest sized pisten that will fit in the block? what cam would i need to use that will pull from idle up to 6000 rpm - 7000 rpm??? how big a cheque would i need to write out??? :D or will it be easyer to fit a BIG port head on top

I was ponderin as we all do from time to time? Can you turbo charge a 5k? Ive seen pix of them but no real info? ANY THOUGHTS??? :D JK

hi everyone, i want to bore out my 5k about 8 thou and put over sized pistons in but i have no idea about it should i do it, will it make much of a difference in power, (will it make a difference at all?) if i do it what else will need to be done. oh and what else can i do to the bottom end to give my 5k more power?

Does anyone know the maximum bore for a 5K? Also does anyone know anywhere i could get flat-top pistons for a 5K? The rollaclub wiki reckons aftermarket ones exist... but coventry doesn't sell them.

Alright guys, I'm sure there's millions of these threads but I'm on iPhone and it'll take a rediculous amount of time so here we are. I know you can use the crow find a cam thing but I'd have know idea what it's like to live with. So, rebuilding the 5k to put in my ke10, k50 gearbox and possibly ke55 diff. Minimal head besides a skim, 32/36, extractors, dished piston motor. Looking for a bit more mid range pull and maybe a little more top end, nothing huge as I was planning to keep factory head gear and hydro litters as I wasnt sure if my datsun/ Chev combo works with the 5k head height. So yeah, any suggestions are greatly appreciated especially …

hey, just wondering, apparently after putting a cam in my 5k, i have to run adjustable rocker gear? ( even though keeping hydro lifters ) just wondering if this is a " have to do " or can i get away without doing it?

Hi guys, I have a mystery cam I bought of kangaroosa. Its had a grind, but no idea what it is. Before I run it I want to check the lift etc. If anyone has a stock cam and a stock set of rocker posts lying around, I was after the following measurements: Root diameter of both inlet and exhaust cam lobes Overall height (from face to face) of the rocker posts. Cheers tom.

Hi, I have a 5K, 97% sure that its high compression as it ping with 91 fuel (lol) it has extractors and a 1n 3/4 inch exhaust and i plan on getting some decent carby or carbies on it.. Now my question is, what specs should I have the cam to if I want it to be 'mild' Mild meaning a bit lumpy and nothing crazy RPM haha .. also keeping the hydro? cheers

hi just chasing the difference between 3,4 and 5k carbies as I'm chasing a new unit to put on a junior sedan and as far I I can tell are all the same in fitment but am unsure wether the jets are any bigger on the 5k ones?? and at around $250 delivered to my door may be a good place to start seeing as all is brand new any help would be appreciated thanks Darren

guys, I'd love some advice before i buy the wrong HD clutch kit. i have read all the guides i can on here, and they all seem to say that a 5k clutch is 200mm in diameter, and 4k is 180mm. now, i measured up mine and its 180 mm diameter, and its def. a 5k engine. so, i assume previous owner/s has put 3,4k clutch on it, and i get the 200 mm clutch kit regardless? or do i order the 180mm? any help appreciated

Hi, can anyone tell me if there is a difference between a 4k and 5k crankshaft pulley, size or weight :y:

I've finally got my 5K running, done the timing, tuned it and it seems to be running totally fine but at 2 points in the revs it totally stops getting power so I get jerked forward in my seat. If I back off a bit I can keep accelleration I can rev higher then it does it again and I have to back off more. It's got a weber, I don't know what the specs are but the previous owner had it on the motor and said he rejetted it and everything and it runs fine at anything but hard accelleration. Also the sump is only just touching the crossmember, which makes the whole car vibrate and rattle. Is this normal? Should I try putting the 4K sump on instead?

Hey guys I've just out a 5k in my 26 that has had a little amount of work done to it at some point, put new carbies on there and got it running. Only problem is that cylinder 1 doesnt do anything! So far I've figured out that compression is good, I've got spark (at the plug), valve springs and push rods are fine and I have fuel as its on the plug when I pull it out. As I'm a novice mechanically what else could I be looking at? I'm assuming a valve problem?

I'm in the process of installing a 5k into my ke30 sedan. Although i noticed i don't have a dipstick for the 5k - so i was wondering if anyone knew if a 3k or 4k dipstick is interchangable with a 5k motor? I'm happy to hear any suggestion as to what else would fit. The 5k is estimated at 140hp with datsun and holden internals, so i don't mind if a dipstick from another model fits, and indicates the right oil level.

hi all, just bought myself a 5k dizzy from the wreckers and want to know where both of these lines from the vacuum advance mechanism are meant to go. Because the 3k one that I'm using at the moment in my 5k motor only has one line that goes to the bottom of the carby. I was wondering if i need to use both or if one was some sort of emission line. :P

Hi, I have a electronic 5k distributor in my 4k ke20 corolla, it has a buggered vacuum advance diaphragm, I'm wondering if anyone knows, are they interchangable with a vac advance unit from a 3k nippondenso dizzy?

hey guys and girls, just bought myself a 5k for my ke20. I'm stripping it down to replace rings and was just wondering if its worth installing aa double row timing chain?? cheers

Picked up a 5K electronic dizzy on ebay recently for just $ 50.00 in excellent condition. It is a Nippon Denso unit with 5K-C on the Toyota label on it. It is the electronic dizzy with the ignitor built-in. The plug to it has only two connections. One presumably goes to +12V ignition & the other to the +ve side of the coil. One wire is black with a red stripe on it, the other is black only. I presume the red stripe is +12V ignition & the black one goes to the coil. Can any one confirm, who has a 5K wiring diagram, showing the electronic dizzy connections ? Does anyone know of the original 5K coil primary resistance specs ? What other low resistance pr…

Folks, Dropped a 5k block and head down at the engine builders to get a "work list" for stuff to get done to it. Please have a look through and offer opinions on pricing, where I might save cash and if there are things I have missed (Camshaft for example isn't there) Prognosis is: Block needs a rebore. Here is the list of stuff he gave me: Block work: - $120 to Rebore to any size (probably 60 thou over because I can) - $40 to deck the block - $50 to remove camshaft bearings and hot-bath the block to clean it up - $40 for new cam bearings - $250 for new pistons and rings, size to suit bore etc. Block work total: $500 - ~$300 for the Head work inclu…

Can Someone PLEASE help me! sob I am in great need of a re-build book or engine manual for my 5k??? Does anyone have one they could send or email??? Many thanks :D ROLLN WAGON

I've been having a problem with my starter for too long and have no idea of what can be the issue. A lot of times it's impossible to start the car when hot. For example, if I go to a gas station I turn off the car, after refueling and paying I try to start it and a lot of times it just cranks reaaaaaally slowly or doesn't crank at all. If I let it rest for 10/15 minutes it cranks and starts like everything is fine. Cleaned all the terminals on the earth wires to the engine block (there's 2 or 3 of them), the starter was recently disassembled, cleaned on the inside and brushes were replaced. Can it be battery related? I've got no space to place a bigger one …

I'm looking for the torque settings for the 5K flywheel & rocker gear. I've looked in FAQ and Google but neither seem to have the info. Thanks in advance.

Hey guys somehow my 5K has snapped all 6 flywheel bolts clean off, does anyone have any idea where I can get some stock replacements? I don't want to use the old flywheel bolts I have lying around, I would rather start with a new set. Tensile strength has to be correct of course.

hey, i think i may have found myself a 5k, but i thinnk it may be a forklift motor.. would need a rebuild and i would be turboing it so it will be getting different pistons anyways.. are there differences between the motors? are they the same? help??

so after buying my ke30 from andy h, a few weeks later my head started to leak water into my pots. after inspection i found a brand new head gasket and a minor surface crack in my head, but the crack had the appearance of one that had been there for years. the mechanic at API engines lonsdale agreed. it looks like the previous owner has obviously had troubles with the crack before then just put on a brand new head gasket to buy him 3 months or so and sold it to me under the impression the car was gold. The head has been welded and shaved by API engines, ive bought a new water pump (because the old one was going to give out soon), and new gaskets for everything…

Does anyone know the tension the head bolts in a 5k engine should be set to? Or know where I can find this?
