Find it strange that they would design a pump that can run fast enough to cavitate when they have no idea what engine/system it is being run on!

Exactly. I knew the rest 😂

As you have removed the engine coolant pump and replaced it with an electric one that isn't linked to engine speed do you think you could also do away with the restrictor plate? Might be worth asking the manufacturer of the pump?

I still have the original oil cooler in place. My coolant sits between 90-95 exiting the engine and I think the oil sits around 85 degrees. I cant remember if that's before or after its been cooled.... Fairly sure I am running 10-30w.

It is possible to replace the oil filter casting completely. You can buy/make parts for this. I used an adapter that screwed onto where the oil filter would go retaining the water cooling parts. Couple of examples.
I used something like this (different thread size)

thats the knock sensor. You probably wont be using it....

Is that "cold"? Mine is connected straight to the 109 guage and works pretty well!
-
My adapter didn't cost a grand! but you know with inflation etc....

You would also then need to find somewhere to mount the clutch slave cylinder.
I can send you my cad if its at all helpful. It was almost perfect.... 52.1mm though. I looked at the spacing from the face of the flywheel. 2 bolt holes didn't line up (internet borrowed dimensions.... Might have been for a different sump design.
-
looking back through I may have used standard bolts?

some photos..... and here is my dry bearing.... https://youtube.com/shorts/33Jcj7Ioo2Q

Well its been a very long time since I posted in here.... I still have it, no massive changes, going through some updating renewing parts etc. The following is a list of work I have completed over the past maybe year or so....
3D printed a snorkel in ABS in about 16 parts and melted it together using acetone.
Reprinted my speaker mounts in ABS, the previous PLA had warped in the hot weather.
Changed the clutch release bearing as its been squeaking. Unfortunately only discovered LOF do an extreme heavy duty bearing after replacement.... 😕
Changed the front axle casing after finding out the mounts were about 9mm too far apart, also wanted to increase the castor angle to get rid of some remaining prop vibration. Its now on the limit of what it can be but is good for vibration.
Changed the timing belt/waterpump. Cant say how glad I am that I did this. One of the bearings was as dry as the sahara and I also found the timing belt was not correctly tensioned 😳 So its always been a bit loose in my ownership.... Fortunately now corrected with a homemade washer in a washer....
I am also making a new android head unit for the car based on an SBC but that is work in progress.
I need to do the pictures another time.... All of them appear to be in different places hiding somewhere!

@jad Hi
When you built Koya, how did you fasten on the flywheel to the 1uz crank, did you drill out crank holes and re-tap to tdi size or use 1uz bolts
TIA regards Stephen
I don't appear to receive emails when I'm tagged 🤦I had someone turn out the inside to fit over the crank and turn down the outside to fit the ring gear. I didn't adjust the bolt holes even though they are very different sizes. It should be the clamping force holding it in place. It might have been better to dowel the holes and redrill to the 1uz pcs but I haven't had any problems. Can't remember what I did for the bolts but they definitely would have had to be longer...

Morning, thanks for the suggestions. Not looking to diagnose or solve any issues. Was just quite surprised at how gloopy the diff was when it was removed. Given how thin ep90 is.... I don't do significant mileage just seemed like a good idea to do while the axle is already in many pieces!
-
Evening, I am changing my axle casing and have dissembled my old axle. The diff appears to be covered in a lot of one shot grease from the CV's. Any recommendations on how to clean it? The internet suggests brake or carb cleaner.... Or should I just not worry about it? I was planning on flushing with some old (but unused) ep90 after a few hundred miles.
Thanks
Jad

Yep sounds sensible! Got a couple of other jobs I'm lining up to do in one go so will be a little while before I do this. Least it's useable at the moment....
-
I'm not too bothered about the looks.... But don't particularly want to be taking the rad out of the car 10 times when I find out it hasn't worked! 🧐
-
Has anyone repaired their own radiator before? I have a very small coolant leak, circled below. I do not use the 200tdi style oil cooler. I can weld, so am hopeful I could solder a radiator.... Any experienced views? There is a chance that it is cracking all the way around the joint, although it might be a crack in the paint. Maybe....

Almost sounds like it might be better to have a larger tank inside just in case LPG stations are few and far between. I thought Europe generally were a big LPG fan. Always found it interesting that you could buy LPG versions of cars in Europe but not here. Although there are some exceptions like the dacia duster...

From memory the smaller tank is 45L, the larger is 55L - from empty to full is around 85L which would work out somewhere close to right as you can't fill them completely full. I think they are this type: https://tinleytech.co.uk/shop/lpg-tanks/single-hole/single-hole-cylinder-tank/
I ran the BLOS on megasquirt for a few years - you just have a second ignition table with the LPG curve on it, and a completely zero'd fuel table. I'm now running multi-point with an LPG ECU, but slowly moving more of the LPG functions to MS - gas pressure correction etc. At the moment it runs well, but there's a few niggles which appear to be because the LPG ecu makes corrections that the MS doesn't know about, even though I've disabled as much as possible.
Elbekko is right regarding the injectors - you would likely need a peak + hold board to drive them. It's also likely that the currents are different to peak + hold petrol injectors (some are, some appear to work) which means modifying most of the peak and hold boards from standard. You would also be 'better' moving to MS3 if you aren't already as this offers a lot more control around dual fuels, and can do all of the gas temp/pressure correction.
Yeah without significantly modifying the the rear bulkhead and outrigger I am not going to be able to accommodate a reasonable size tank so think I am stuck with one inside!
I think that I am running MS2... It's been quite a long time since I have played with it!

We're planning something like that for @Escape's car.
This definitely needs a good write up 😉

I looked into that previously and I think the main issue with using megasquirt to drive both is that most petrol injectors are low impedance and LPG injectors are high impedance or vice versa and if you get it wrong you can blow the ECU. I think you have to run an external control for the different impedance injectors or something. It looked a bit more hassle than it was worth but if anyone has any further experience that would be great!

I would be surprised if anyone ever performed the fluid dynamics on such an old engine with or especially without the impeller....
