I'm also thinking of getting some dished oversize pistons, or should i get flat ones?? can someone help.

Hello guys, I have a liteace with 5k engine(1475cc, gas, 50KW) but my cylinderhead has broken down. Does anybody know where I can buy or does anybody sell a cylinderhead for my engine?, I am searching for one since 2 months ago :yes:

Hi everybody. Have got my 5K in KE70 and it has been misfiring in in high RPM's, more so when the driveline is under load. I have played around with the timing to see if it was that, but can't seem to find a sweet spot. So wondering what other issues may be causing this to happen. Could it be carby? Motor is a worked 5k with 35/75 Cam, ported head, solid lifters and probably lightened flywheel (I didn't build motor) with a 32/36 weber bolted to the top. 160/165 air jets, unsure on fuel jets. Any help would be greatly appreciated! Cheers, Vince.

Any one know were I can buy lifters for a 5K?

i have a 5k in an 81 starlet (in NZ) which has problems with the valve clearances. they are out, but they have hydraulic lifters so i can't adjust them!! can the hydraulic lifters be replaced with solid lifters from another k engine? or is there any other way of replacing them with solid lifters? or do i have to go and buy now hydraulic lifters? also i am thinking of putting a 4k head on it, would i be able to use the lifters and pushrods from the 4k head on my 5k? and is the cam the same with hydraulic and solid lifters? cheers

I have a 5k with just a bit of work done to it, 85hp at rear wheels at 7500rpm in a KE30 2dr sedan. I recently broke a valve spring as the cam has a lot of lift. Fitted new double springs with about 100lb seat pressure but chewed a lifter straight away. Replaced all lifters and runs ok again but to save the hasle of hydraulic lifters i want to change to solids. I know i have to have to cam hardened and that chev solid lifters will fit and pushrods i will change for 1 piece items of the required length. My question is: will the adjustable rockers from a 3k or 4k fit on the shaft of the 5k? I've been told that i might make an extra 10hp and an extra 500pm to be 95hp at 8000…

I hav 5spd manual(k50), KE70 with a 4k-c. Jus wanted to kno if it would be worth it to put a 5k into it. what sort of power upgrade should i expect if i put a 5k with sum sort of carby upgrade in it. Is it worth doing and what would else, besides the motor would i need to do conversion. Any help or info would be appreciated. THANKS

Hi, Just been cleaning up a 5K I have ready to install it into a car of mine. But I was interested to know about the carby they run. As the one on this 5K I have is well dead. So I want to use the one off my 3K will it be jetted right? Also does anyone know the compression one of thee 5K's run? Mine is a dished piston motor if that helps? Cheers Cameron

hey all i heard rumour of a 5k injected turbo? any1 kno if theres any truth to this n if so any idea where to pick one up? i don't imagine they would b easy 2 find....also what were they from...was there a turbo hiace or something? lolzzzzz

Hi guys, Torqued the head up on my 5k and slapped all the rocker gear in. OH OH valves hit pistons first go. Bugger. I pulled the rods out, they were about 156mm long, so I dug around a bit and found some 150.5 long items and they went in perfect. I'm guessing the longer ones are off an early K engine? (Kangaroosa, you might be looking for some longer rods I think they're the ones I got from you with the cam!) Anyway, the shorter rods gave me lifter preloads from 1.1-1.6mm as best I can measure. For you other 5K builders does this sound about right? I originally measured one at about 2mm but I redid it and got it about 1.6. The longer lengths are on the i…

Hi all, I have bought a secondhand 5k motor today out of a Liteace van, and I noticed that on one side of the sump there is a solenoid with a wire coming off it, also along the manifold side of the head are some small pipes that screw into the cyl head. :S So if anyone has an answer about what these two things are used for, then that would be awesome. :y: :bash: as my other 5k in my ke20 doesn't have this stuff. Is this 5k I picked up today a later or an import motor????? :yes: Cheers, Mark. 8| :y:

Hey, I've got a 4 door KE55 getting painted at the moment, it's pretty stock but i've just found a 2 door sedan with a 5K motor. the shell needs some work so i thought i'd chuck the 5K in the 4 Door for the time being. Anyway, my question is will a 4K head fit on a 5K bottom end or a 5K head on a 4K bottom end? or is there a way to make it fit, e.g. drilling out oil/water ports ect.? Might be a stupid idea but i thought the 4K head on the 5K bottom end would bump up the compression and go a bit harder and that putting the 5K head on the 4K bottom end would de-compress the motor ready for a turbo. Any advice will be appreciated. Cheers, Tom

Hey, I am almost finished puting a 5K in my KE70. I was just wondering how much oil the 5K hold as i only have the dipstick off the 4K. Are the dipsticks the same. Any help would be appreciated. I have searched the forum and can't find anything. Thanks, Mitch.

hey guys, iv got a 83 ke70 with a manual & 5k conversion.. long story short. I was driving home the other day, and the oil light had come on as i was coming up my street, i got home and checked the level.. was full and rather clean. i started it up again and the light WASNT on.. but after a few minutes it slowly faded on again, and the ( rockers? ) were noticibly louder then normal.. so i turned it off again and checked the level.. was still full. I'm guessing my oil pump has shit its self? if anyone could help me work out the problem that would be great!

Ok here we go! 5k block,dished pistons machined to flat tops,block decked to suit,4k head,isky chevy lifters,430lift cam,fully balanced,datsun 12a push rods,new oil pump,all new bearings big end,mains,cam,all meassured 1.5-2.5 thou clearances. Now for the problem this is the third cam & lifters we have put in in 12 months all been the same and getting very pissed of. Start up cold 60-70 psi oil preasure once warms up drops back to 8-10psi at idel 1000rpm. Running Penrite 25-70 extra 10 oil,has any one out there had same/similar issues as this? would like to here from you so as we can sort this problem out. Cheers :- Stuart (Thomas dad).

Hey guys, Just after some input. I am currently running a 4k in my KE70, I have recently had ideas and dreams for more power so thought a bigger engine would be fun. I decided 5k since it seemed most of my 4k running gear will bolt straight onto the 5k. I found a 7k engine in good nick, which I've been informed most of my 4k gear will also bolt upto. What should I do? Cheers, Jake.

Can anybody tell me if these are factory 5k pistons?.. or are they aftermarket? :)

hey guys thinking bout buyin another rolla/toyota. 5k how much rwkw u able to get out of these things with say 2g spent on it. not include motor box etc. twim carbies head work, reground cam etc etc.... its either 5k or spend a bit more and going 4age NA.. the car is still undecided.. either ke20, 36 or KP36 publica. cheers guys.

So recently bought and had installed a recon 5k motor, had all my old stuff of the 4k put on there. First question is while wearing the motor in like a grandpa ofcourse I've been noticing when I slighty put my foot down while not under load and in low revs I get a loud almost tapping sound? Second question is it worth putting a 5k started motor in or is the 4k one plenty enough? Think my current one is struggling so wanting to replace shortly. Thank you in advance Scott

Hi guys, I'm having some trouble with getting some pushrods for a 5k. We bent two last season and have been chasing some replacements, unfortunatly with poor results. The local toyota parts department got us in what they called a 5k pushrod but it ended up being way too long compared to what we took out :cool: . The ones we had in the engine measured 150.5mm from the tip to tip and 8mm in diameter and looked identical in design to the "new but too long" ones toyota gave me, so the ones from the engine where definatly a toyota looking item. I tracked down some crow cams ones which are bloody strong but may be causing some valve train problems :hmm: . I'd like …

Hey all, I bent a pushrod in my 5K and I'm having a fair bit of trouble locating a new one. Toyota keep sending out the wrong one and the wreckers don't seem to be able to help. The pushrods in my 5K are roughly 15cm long. Firstly is this the right size that should be in a 5K and if it is why is toyota struggling to GET IT RIGHT. I would also like to know if all K motors have the same size pushrods and if anyone is Sydney has a pushrod that they think will suit or if anyone knows where i should look for one I would greatly appreciate it. Thanks, Mitch.

Hey there people, Well it's a long story, but I'll do my best to cut it short :lovin: I ordered some new 5K pushrods from Toyota last week and went to pick them up today. Basically got there, compared my one from my engine to the new ones, and hmmm the new ones are too long. So, I ask the guy to have a look to find the part number for the pushrods from the varied 5K models (flat top pistons/solid lifters). So anyway, the guy goes and gets help from another guy. So now two people there ask me if I am certain I have a 5K and with my response the guys looks through the computer muttering stuff the the first guy, "Check the YH** Tarago, I think they had 5K's" :D Funnily e…

I am doing a head job on a 5K motor. The hydraulic lifters have already been replaced with solid adjustable ones. Unfortunately upon inspection, one of the push rods is bent & needs to be replaced. Where or what car would I find a usable push rod? Clive S

Hay guy's just a couple question's i have a 5k its in my KE36 wagon that iam scrappen soon I'm keeping the 5k motor and ke55 5 speed box. And i just want to no what kind of problems i will come across when i put the 5k and the ke55 5 speed in my 1978 ke30 ;) cheers shaun any info would be great thanks

Long time reader first time posting! I'm unsure if this is in the right place but here we go anyway I've been looking into putting a 4k head onto a 5k block, I've done some searching and i couldn't find any confirmed information as to what lifters and push rods that are needed. If anyone has this information that would be amazing! Also I was winding if this combination of parts will work together Soni don't waste money on something that I don't need 5k block 4k head with rocker gear 4age pistons and rods from what I've read holden solid lifters and datsun a12 push rods soul work but not confirmed Any info would be appreciated Thanks

hey all, iv got a 5k with 32/36 weber? ( i think ) tighe 25/65 cam 10:1 compression premium 98 fuel i got it all back together today, and it was running fine for about an hour, i turned if off, to put a stronger spring on the throttle return, and didnt like it so i put the old one on again.. started it up, and then all of a sudden it just wouldnt idle.. it kept stalling.. so i turned the throttle up, and it will idle at around 1200+rpm, but if i slow it down to about 800-1000 it runs for about 5sec, then gets real rough and stalls.. is this because of: carby needing to be tuned? timing is wrong? or my dizzy needs to be adjusted? video of …

ok guys sum of you may know i picked up the qwad throt injected 5k race motor of ke25racer ok now here is the problem. ? we start the it up runs fine for the first 5 or 10 min then its nice and warm then it starts starving for fuel what is causing this to start gasping for fuel. ?? we have put a fuel presure gauge on it (vl turbo pump is 95 psi and it sits on that till the motor warms up and then drops rapidly down to 20 or 30 psi) ? ok guys any and as mutch help needed have had this happening for a couple weeks now and just can't put out finger on it. KErolla :) with love, the spelling fairy

I have just started to build my self a ke30, so far have lowered it,17 1nch mags, new panel and paint and prelude seats. That went all good but I'm not to clude up when it comes to the engine side of things. I only no what I have read, with no real knowledge of engines. I have got myself a 5k engine that has has the head shaved,ported and polished, 2t vales with hardened valve springs, a street ground cam (half race cam), lightly balanced crank.pistons and rod, and a set of 2t twin carbs to start things rollin. I keep reading about people changing the lifters to solid ones, so my question is with what I have done do I have to change the lifters or will I get away with wha…

Ok as the title says I have a 5k newly recon motor in the KE70. Current mods: extractors, 36/32 carbie, 5 speed box and exhaust system I'm hoping the get more power out of my car but to also learn more about my car and cars in general. I've read the how to build a tuff k motor and it goes in to great detail of the amounts of possibilities I have to which I can do. I was hoping some1 could tell me that something a novice could do to my internals to gain that bit more out of my motor? Sorry about the layout of the post Engrish aint my strength thanks Scott

hey i was just wondering whats the highest anyone has seen a 5k rev too

Hi! I have D shaped pistons and head with lugs under 1 & 4 cylinders. I'm doing solid 3F lifter conversion and need pushrod lenght and original parts number for that pushrod. Heard that it was same as 4K-u? We don't have 4K-u's here in Finland so that is why I need parts number to order from Toyota. Will 3K or 4K rockers work? Thank you already! -Jansku99

Hi, bought myself a 5k gear reduction starter today and was wondering what goes in this hole or what it is for.

Hi everyone. I have a 5k in my KE70 and I've broken two starter motors in the last 4 or 5 months - however long I've had the 5k in! It seems that the one that most recently broke down was due to the solenoid. It was an NRMA replacement item, so I wouldn't have expected it to break! (It wasn't brand new, but was on a guess less than 70,000k's fresh and was in good working order). 1. What possible causes could there be to the starter motor's breaking? 2. Is it just a common thing for starter motor's to break on K motors? 3. Best/cheapest options to fix! - brand newie (cost?), 2nd handy from wreckers (cost?), recondition? 4. Any experiences people have had. 5…

Guys, I took my 5K for a burn yesterday and it got too hot. I got the radiator cleaned out (about 30 percent blocked) and today it still overheated, although it took longer and a much more energetic drive to do so. I've front mounted a davies craig thermo. I'm getting a lot of "blowback", lots of air bouncing off the radiator and pushing forwards. Yes, before you ask the fan is running in the correct direction. Has anyone ever seen a shroud on the front of a rad? I don't like the idea because you lose a lot of open road airflow, but in this case it will definitely improve the fans effectiveness. Any other ideas on how to get the temp down?

I recently bought whitey of grimwolge to doner a few parts to my KE55 and a mates KE70. Well what I was wondering was what cam people have had the most success with a 5K. I'lll be running a 32/36 weber and extractors to begin with, using a 4K head, ported by my mate (thanks Mick). I'll be upgrading to a single 45mm DCOE carb at some point too. Whitey has a massive 88 - 42 cam, I don't think the 5K would be too happy about that as a streeter ... or should I wait and see now nice it rumbles. I'll be running 202 Holden H/D valve springs, because these were inteded for a stage 3, 6 cyl cam, should I only use the outer spring? They are bloody hard eh. How much …

Does anyone remember seeing the ke20 / ke15 with the injected 5k turbo engine in it? i think the picture of it is between two skylines??? Any one 'member? :dry:

hey guys can 5k webbers fit on to a 7k? I'm led to believe that 4k extractors can fit on a 7k, but also some parts can't fit. would it do the trick? help would be great, cheers. :S

Hi, Ive been reading up that 32/36 DGV weber are a good upgrade for k series motors. I'm trying to work out what cars these come of so i can get one from the wreckers and get it rejetted etc. I think XE-F falcons have them, but they have a 3.3l which is considerably bigger than my 5K. I just wanted to make sure that they are ok and if they can be jetted down enough to suit my motor. Also if anyone has done this conversion their advice would be helpful as ive searched the forums and not found much. Cheers

Hey guys I'm looking at a very cheap liteace van and was just wondering if anyone knew the years that the Liteace had the 5K motor in it? I've tried searching and google but haven't found anything. Any help would be appreciated. Also the car owner won't be able to tell me what engine it is until 3:30 today so it would be good to know if it could possibly have a 5k

:) I have a question for any one that can shed some light on the subject, I currently have a KE20 corolla that I used for racing through country dirt roads with friends, I have retired the car to the paddock to teach the children how to drive as the car is very easy and reliable for them to learn in, here is the question, I am building an engine and need some info, 5k engine, 4K-e, injection, Big port 3K head, BMW bolt on super charger, Silvia intercooler, will the compression be low enough and will the 3K head match up with the 5K block without much modification?
