Yeah this is the A20 the 14.5 was with the ET1 bored out to 2.0l with super short manifold but that had much higher CR ratio and stock valves the A20 has super low CR and huge valves! But the block is getting tired now after about 20ish thousand miles registering about 160-165 on all 4 cylinders when cold which isn't great. Although if i try a thicker oil may bring this back up a bit! Main issue i think is piston slap too much clearance and engine not getting hot enough, but the engine is producing so much force on the water pump that if i use a thermostat it rips it and the seal to pieces!! So have to run without! other alternative is to run a heat controlled electric pump which would also free up a few bhp from nut running a belt for the pump and also have much better control over temps and stuff. Looking into it but off course more money and weight!! lol!!
But when i get this new exhaust should really fly and also have to start work on a new engine soon as I don't think this one will last too much longer but we'll see I'll keep driving it till it pops! Have plenty of A20 spares so not so much of an issue! If i run out could allways try and drop in a B20A hehe but would probably go back to ET1 as that was such a good head!
Well anyways going forward lots to do and work out as usual and i really need to upgrade that ignition and also get some new carbs either bike ones or another set of webers. I'm fancying bike carbs though as cheaper and better and would be easy to fit onto my existing manifolds if i chop the weber flanges off, I'd probably stick the webers on the B20A though!
