    Distributorless 5K Engine

    Wasn't aware of slack on the chain contributing to timing variations. Won't you be happy with a wasted spark system?

    Distributorless 5K Engine

    Banjo search for Speeduino. It's a fully programmable ECU developed in Arduino that can cost half of a Megasquirt price. I've spent some time thinking on a distributorless ignition but what to do with the oil pump? It'll still need the shaft in there for that. And that could be used as camshaft signal for the independent ignition.

    Enlarge head ports

    Yes I know I can make gaskets. Not having the template to do it is the issue here... As soon as I get that one piece gasket I'm gonna create a template of it so I can get it done in the future.

    Enlarge head ports

    Finding that gasket is going to be a nightmare. The one on eBay with shipping costs more than 30€. Already PMd oldskewltoy on porting tips, and altezzaclub to see if sending me a gasket is "doable"

    Enlarge head ports

    I have a twin squish head that I want to apply on a worked 5K and I want to enlarge the intake and exhaust ports. I know that the one piece gasket is very good to match but I can't source one in Europe (at least at a fair price). So I would like to ask for tips on the sizes of the ports. I was told the one piece gasket is 33x30 on the intake and 27x22 on the exhaust. The intake seems fine but the exhaust sizes are almost the same as the stock head... What's the safest sizes I can go? Thanks
  6. 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...
  7. I think early 4Ks had flat top pistons and double row chains (here in Europe almost every 4K has D dished pistons). I also upgraded my 5K from single to double

    Lower Temperature Thermostat

    I already knew about that ToyheadAuto thermostat but was looking for a cheap option as I was told there was a Hilux or Dyna or something that had a lower temp one that fit K engines. I've been running a Payen paper headgasket on my 5K with above 12bar of compression pressure in each cylinder for almost 2 years with lots of punishment and still goes great!

    Lower Temperature Thermostat

    I get what you're trying to say, and believe me I'm always thankful to anyone who takes some of their time to explain me something. Let's imagine I live in the hottest place on earth, I don't have any radiator selling point in a range of thousands of kms, but I have access to that specific 78°C thermostat. Will it fit? Hahaha it's really just a yes or no topic

    Lower Temperature Thermostat

    That's exactly what I need, regulate the temperature of the cooling system to a colder temperature. I will run a very modified 5K with a Nissan Primera radiator but need to control the temps to a step colder just to keep it safe. I'm not running into any issues, I just want a lower temp thermostat to play safe. Factory thermostats weren't designed to modified engines pushed way harder than the vehicles were created for. If I noticed a difference from a 88ºC one to a 82ºC, that 78ºC might be exactly what I look for. I just need to know if it fits, considering what I exposed on the 1st post.

    Lower Temperature Thermostat

    I just need it to open a bit sooner. When punishing the engine the temp goes a bit hotter than normal operation and I want to keep it safe.
  12. A long time ago I bought a 5K assembled head that had some work done to it and was ready to be installed (face machined, all cleaned, etc). It had a brand new thermostat installed also so I just dropped it in. First time the engine ran the temperature went past the usual maximum point before cooling (signal of thermostat opening). Took the thermostat out and found it was an 88ºC one while I've been running an 82ºC one. Later someone told me he found a 70 something degree one but wasn't able to provide me a part number. Today I've done a bit of research. Started with my 88ºC part number (Gates TH14088G1) and was able to find several vehicles where it fits (Ford, MG, lots of Toyotas, etc). When I looked for the Daihatsu Charade G100 GTi there was a 78ºC thermostat (Gates TH29478G1) on the list along with the Gates 88ºC one. But there's a small problem, the sizes are very different and that's where I need your opinion: Gates TH14088G1 Gates TH29478G1 Both of them fit the Daihatsu, so is it safe to say they'll fit our Ks?

    Oil pump failure

    That's a google picture. I have a 5K but I'm running all the Starlet gear, including the Starlet fan

    Oil pump failure

    You can see it there

    Oil pump failure

    Banjo the Starlets had that thermostat housing with the hole because it's where they have the temp sensor for the electric fan
