A14 HELP NEEDED !!

Postby iamkiwiana » Sat Aug 12, 2017 4:07 pm

Hi all, I have an A14, it came out of an sgx b310, the vin stated it was the 80hp model, but it is a round port h72 ?? is there any differences to the block between the higher and lower hp model A14s? or just the Head ? As I have an h89 head I was planning to put on the block, would this bring a lower hp engine to be the higher hp model? and what modifications would be needed for the head swap ? Thanks for your help :pc:

The blocks will definately be the same.
Most A14's Ive seen had the open combustion chamber H75 (or H72?) heads.
your H89 should be an improvement.

I would think the cam will be different also, as the low horse power was an economy engine.

How do I find out what head is on my b310s a14, it goes like stink and one of the previous owner's built it, but I have no clue what the head is or what internals it has as the cam is lumpy as and it revs out to 8. Where do I check what head it is?

Remove the rocker cover and you'll find a casting

No need to remove MAnifold to check ports. Oval ones have a water jacket on the bottom of the manifold and are much deeper in the manifold, post up pics if you want, I am sure you will get opinions on which it is without tearing it apart. A pic of the casting will identify it also I would think.

Hi guys I havw taken some pictures to see if you can help identifying what sort of ports my A14 head has on it and what head it actually is.
