  1. Hi all, I'm in the middle of an engine rebuild on my 1965 Hillman super minx (1592cc engine) and have found that my oil pump is bad. I'm having a hard time finding a replacment but can get one for the newer hunter engine 

    Does anyone have any experience swapping them? I have read that you need to retain the original gear as the hunter on has an extra tooth and will put the timing out. 

    Im also guessing that the pickup might need to change as well.

  2. Built up the rest of the manifold. It was a little rough (ie not grinding down all the welds) as I planed to heat wrap (not sure any more though)20161229_150121_1484437023711_resized.jpg

    Once Installed I had to build the synchronization link between the 2 carbs and run new fuel lines plus accelerator linkage. 

    I decided to work late to get it all done. Finally finished it at about midnight and thought I would lake it out for the first run. Everything was going well until I pulled out on the the main road and the accelerator pedal fell to the floor. Luckily the idle was high and I managed to ride the clutch until I got off the road. Turns out I didn't put a split pin in the accelerator linkage and it was lying on the ground. After some tweaking I was good to go again. Definitely more power and acceleration.20161223_153609_1484437027860_resized.jpg

    Hopefully I'll post a video of it running soon.

  3. As this engine has the intake and exhaust manifolds in one flange I have to build the Intake and exhaust at the same time. Using Solidworks I sketched up the flanges and got them laser cut out of 10mm mild steel. Shopping around I found that Stainless Design was pretty good on price and and had good service (also have a work account with them).

     

    I started looking around for Extractor calculations to get the right size pipe diameters and primary lengths. I found it hard to find a reliable formula as some of the sizes seemed too small or too long.  In the end after talking to a few people I just went with best guess. My first design was 4-1 style extractors but after reading a few forms and doing some research I settled on a 4-2-1 design. Lucky there is quite a bit of room in my engine bay.

    In the end the Intake is 38mm, Exhaust is 32mm Diameter for the first 315mm then 40mm after the join with a total length of 1100mm finishing with a 50mm section

  4. Hi All,

     

    I though I would start posting abut my latest upgrade to my 1965 Hillman Super Minx. A few months ago I bought 2 Weber IDF 40 down drought carburetors to fit. I know it will never be a speed daemon but I just like building things. Carb's are new to me as I mostly work on injected engines so this was bit of a learning curve (still is). 

    I will add some more posts of the build when I get more time.

     

    Here is a photo of the carbs when they arrived

  5. I want to keep it Hillman stock at the moment, I may plan to re power it sometime in the future. Since they did come standard with the 1725 engine (mine just missed out) I though I could get away without cert. The motor also comes with the overdrive gearbox that I want. Would the hunter box bolt up to my 1600cc engine as it is? I may just consider replacing that. I have had to put seat belts in the back anyway (kids with car seats) so theoretically I need to get Cert but might as well make all the changes before doing it.

     

    If I do re power it I would go a newer engine with EFI, as I'm an electronics / software engineer I have no worries getting the electronics to go

     

    I will post up some more pics as I go

  6. Hi all. First time posting here, looking for some advice.

    I have just bought a 1965 Hillman Super Minx. The car is in good shape, minimal rust WOF and REG, drives ok for i's age. Since this is my hobby car i'm looking to do some upgrades. It has the stock 1592cc engine with 4 speed manual (no over drive). I have 2 thoughts on the engine.

    Option 1: Stick with the stock engine and do the following

    Weber carb

    Build new intake manifold

    Build new headers / exhaust

    Port / Polish head

    New cam shaft

    Option 2: Find 1725cc engine and do the same as above.

    Would a 1975 Hillman Hunter enging fit in?

    Engineering parts is not a problem as I have a full work shop. My main question is, is it worth going for the 1725cc engine or stick with stock?

    Thanks for the advice.
