If you have your old camshaft then find your most local camshaft grinding place and send it to them to regrind for you.

For oversized pistons, identify which ones you want and try your local motor factors shop.

I used Mazda UC 77mm pistons and they were on the shelf at my local shop. I sent my Camshaft to Camtech in Australia.

When i modified my A14 I used mazda UC 77mm dia pistons and a camtech 621 cam together with an A15 crankshaft, H89 head and a 38DGAS carb.

Cam came with double valve springs and a stated max RPM of 6800.

Big improvement in power felt and it pulls from 1500 or even less in 4th gear.
Not yet tested on Dyno as my next step is programmable ignigion but very happy with my mods.

How about that cast iron very heavy bracket that bolts onto the block and supports the alternator ?
that must weigh a few kg.....

I think you have to just buy a new one.
There not expensive.

No, not normal, it means your pump seal is leaking, time to get another one.

there are plenty of them on Ebay...

The pipe at the back end of the block is the crankcase breather.
Dont put coolant into it !

My H89 head had a fitting for a heater but it had been crimped shut. I think by the factory as i have seen others done in exactly the same way.
Heaters not required in Thailand..

This is what i managed to get for my rebuild, though i only ended up changing the main input and output bearings.
This was about a year ago.
Some of the bearings had extra metal oil shields on them which i had to remove.
I took me quite a while to find the correct numbers which is why i asked if you would post some pictures. I couldnt find the part numbers of the needle rollers at the time.
I see DD has updated the Tech-wiki for future reference.
Thanks DD for your continued efforts in updating this valuable resource.
