    Fuel tank frame is welded in and floor riveted to the frame, also bent up some aluminium straps to hold the tank down, I may redo these in stainless steel I'll see how these ones go.

    4k timing chain broke, great fun replacing.

    Jesus.i started reading that with interest But i got to the oil pump shimming bit and lost interest because all that does is make the startup oil presaure higher and increase wear, which makes the entire post seem sus. Ive also had a realy fukn bad day with my car, carby rebuild has sent me backwards, now with a stumbling hesitating intermittent idling car which randomly fills up the throats with fuel, plus completely cracked spark plug insulators and just a bad amell everywhere.

    Well, the rest of the head gasket has just one steel ring holding in the fire.. maybe you don't need more between cylinders! Here's Phil's project, a 4K block over-bored by 6mm.

    Hatch coming along. Been using ppg 1k acrylic primer filler. Its a great product. Amp is great but I need a sub.

    Perhaps it would be nice to see 4x oversize 5k pistons sitting upside down on an inverted cylinder head in their rough positions, to see just how small the gaps between them are.

    But theres only so much distance between the far side of cylinder one and the far side of cylinder 4. Obviously it works, or we wouldnt be having this discussion haha, but my concerns are about the ability to fit 4 x 83 mm bores inside the dimensions of the 4k head and block. I think its just all incredibly tight on a 5k, based on all the pics on the net.

    The head is just a flat surface where it sits on the gasket, so it doesn't matter how big the bore is. Wet liners were used too, they had an O-ring or similar seal at the bottom where they sat in the block and water circulated around the liner. Check out the twin-cam 4K, philfrederick bored a 4K to take 4AGE 1.6L pistons. A few guys have done that.

    Not only that, but the part number for the 5kj head is the same part number for the 4ku/j head, confirming it is the same size.
  12. A Finnish company sells 83mm Wiseco pistons so I guess a 5K can take it? I also don't get it how does the 4K head fit on a 5K with this having so much more bore available...
  13. Very rare, and hard to find complete set of tail lights from a TE27 Toyota Corolla Trueno Model. These can also fit various KE models. I had them fitted to my 1973 KE25. These are complete with the bezels, the reflectors and the electronic units. The frames would benefit from light restoration. The centre piece is a fibre-glass replica, but would not be noticeable once painted up on on the car. It needs some work to make it bolt up as you can see. Looking for £500 ono. Shipping available worldwide. I am UK based.

    Nah mine has std liners, theres heaps of meat. I think for a std 4k liner the bore is extended form 75 mm out to 77mm, no where near a 5k after 4 succesive rebores at 81.5mm. (80.5 std + 0.25, 0.5, 0.75, 1). So look its not actually the water jackets that concern me, I can't understand how the 5k can be bored out at all and still have enough meat between the cylinders. Just look at a std 5k headgasket, there is litteraly no rubber between each cylinder. I recon itd be like a piece of sheetmetal seperating the cylinders haha
  15. That's why I asked earlier in this thread, whether the boring out of the block, to fit the liners, ever broke through into the water jacket, in the area you are mentioning. I once read, that modified engines for 1/4 mile dashes, just fill up the water jackets with "Araldite", or something similar, to prevent the cylinder walls flexing, when they are bored to the limit, & become very thin.

    Thats how i found it. Yeh its still I'm the sump haha. No broken pieces anywhere to be seen. Remember everything here is dirt cheap, so its possible its just an aftermarket piece that is so crap it just broke. Kickn, so why are people always saying not to bore out a 4k to 80.5 mm for 5k pistons? Does the 5k block actually have more meat on the cylinder walls along with thinner water jackets or s9mething like that? And if so, how is this possible when there is the limitation between the two middle bores. They are so close together even on a 4k.

    No, have it more or less just sitting there at this stage. Zip ties so it doesn't fall off- I will most likely be making new brackets I think. Shouldn't be too bad. Yes, very proud of her... turns heads and I can't stop looking at her! Can't wait for rego!
  18. Hi Jeremy ! So where is the missing link ? Did you retrieve it, or is at the bottom of the sump ? To my knowledge, the chain is all one piece, with no removable link. That's why it is necessary, when fitting, to attach the chain, to the two sprockets, then slide them onto their respective shafts at the same time. The joiner pins in your pics, don't show any sign of wear, adjacent to the missing link, if it was rubbing against something. Was that how you found it, or was there some broken bits, still attached to the chain. I'm interested, as I've never heard of a K series chain breaking. Cheers Banjo
  19. Having just completed my KE30 4K-U Thermofan Conversion, using a Toyota Echo Radiator & fan, I have a few radiator related items in excess for my requirements. The radiator was recored about 2 years ago, & is still in very good condition, & was working perfectly, when removed from the KE30, a few weeks back. It has a radiator cap (13 PSI) that is relatively new, & works fine. Comes complete with all mount bolts. Will suit both manual & auto KE Rollas. $ 55.00 pickup south side Brisbane. Will post if necessary, but postage will be at buyers expense. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- This is the two piece shroud that attaches to the rear of the radiator. It is in good condition, & has no dings or damage whatsoever. Comes complete with mounting bolts. $ 15.00 pickup south side Brisbane. Very bulky for postage, but I could dissemble into two pieces & arrange postage at buyers expense. _________________________________________________________________________________________________________________________________________________________________ Two (2) radiator overflow bottles, with mounting bracket. Very good condition. No cracks or breaks. $ 15.00 pickup south side Brisbane, for all three (3) pieces). Can arrange postage at buyers expense. If someone wants to buy all items in this listing, then the price is $ 75.00 total, pick up south side Brisbane. Send me a PM, if you have any questions or queries. Cheers Banjo
  20. Last week
  21. All my suppliers sell .5,1.00 and 1.5mm(or .020, .040 and .060") oversize pistons. I also know of at least 5 83mm 5k engines getting around. So definitely can be bored.

    It’s looking fantastic. You must be so proud of what you have achieved, it’s come such a long way. Did you bolt the front bumper to the front guards? You can guarantee you will then crease the guard lip if you ever touch anything with the bumper

    Right. Big news.. sorta And apologies to you, and my future self, for the lack of updates between the previous post and now. Regardless; the car is more-or-less back together! I have been very much enjoying sitting back in awe of what's been accomplished... but I'll save all the sappy stuff for the big one.. rego! Car went back together relatively easily. I did however learn that masking tape is a biiiitch to get off things once it becomes old. However, that said, I am thankful I used at least something to hold certain bolts/nuts in certain places... it certainly aided in the midst of the "where-the-heck-did-that-bolt-go?" Situation. The interior, though it's pretty banged up, is great to see put together. I loved the fact that it took about an hour to put it in! A lot of dirt came off the parts. It's been a while. I am not entirely happy with my rear window rubbers and how they sit. Front bumper apparently doesn't fit anymore! Jono C. (Green Sprinter) had mentioned he had difficulty refitting his because the mounts would bend apart and away from each other... but i have a different problem. Mine no longer reach the bolt holes. The chrome bumper itself hits the stonetray/valance/whatever you wish to call it before the mounting holes line up. I suppose this is an after-effect of all the surgery. By the seems, this means my car is ever so slightly narrower in the front. By...2cm or so peobably. The car looks amazing. Yet there is still much to do. In fact.. i have a list written on my phone that still does not fit on the screen. But, optimism is key. It's all uphill. She's closer than ever before. For now, just gotta keep my head down and cross things off the list. And of course enjoy the occasional sneaky drive ;)

    anyway so heres that damn chain, i found it. The part number gives me these hits http://www.japan-parts.eu/?parttt=&part=13506-13020&regi=EU&cars=ok

    this piston is at TDC. it has about 1 mm worth of bore involved in the equation. Note, you can see the liners clearly here

    4k timing chain broke, great fun replacing.

    but thats only true if the combustion chamber isnt the size of the bore, which it is on these motors; the combustion chamber includes some of the bore when the piston is at TDC. The piston stops about a mm before the deck or something like that. So if u expand (bore out) that smaller compression chamber area along with the entire swept volume, you are in fact enlarging one half of the equation, the compressed half, meaning they both cancel each other out, mathematically. That smaller half of the equation, (the little TDC combustion chamber) is more sensitive to change, because it is smaller to begin with, so increasing it marginally, has a significant effect on the entire equation.

    I think you will get a compression of the distance between the top of the piston/head gasket and the head, versus the stroke. So the air column in your 73mm stroke is going to be jammed into about 3mm, about 25times. Think if you kept the same combustion chamber and bowl in the piston, but bored it out to.. say, a metre! There is a massive flat area around the piston bowl going up to meet a massive flat area around the combustion chamber, compressing that volume 25times. Soon the combustion chamber and bowl in the piston would be so small that your compression ratio would be 25:1. So reboring it wider must give you a compression increase each time, but small rebores will make a small difference. That's providing the piston shape stays the same of course, and it reaches the same stroke height. Someone used VW pistons to get a flat-top piston a few years back, but I couldn't find one with the right gudgeon diameter and deck height. You might be able to get some really interesting parts we wouldn't see in Aussie.

    4k timing chain broke, great fun replacing.

    Yeh tge compression ratio will remain about the same on this motor, as the piston does not travel all the way to deck height. For compression ratio to increase with a rebore, the piston would have to have always (before and after) reached absolutely 0 clearance between cylinder head and piston crown. This is because, in my case, with the very small clearance between crown and deck, plus the distance between deck and cylinder head (head gasket), every bit the bore gets larger, means a larger "clearance volume" proportional to the increase in swept volume. So unfortunately, i can't gain compression by boring out. In fact i have evidence / proof. The rollaclub wiki page shows blocks and associated cr figures. The 4ke and the 5k both share the same piston types introduced in 1982 just proportionally wider for the 5k with the same increase in dish volume. The 5k has less compression ratio due to its larger clearance volume. 4ke 9.5:1. 5k 9.3:1
