i stay in Pretoria,
i did fit 2lt sentra valves and i have double valve springs, let me give the complete kit starting on the head,
A 14 Head, 2lt sentra valves,VW polo Valve guides, Alfa valve springs,
The Sub, well i fitted a A 15 Carnk, with 1500 pistons Giving me a total 1540cc ( I dont know if that is where my problem is for not getting more) standart conrods. and a 262deg van der linde cam, and all was balanced.

It just struggles to climb in refs.
i am still running the standard feul pump can that also be a problem to get more feul on high rpm?

I am working in that direction but as i did work my 1400 and i heard of peple geting 7000 + out of the basicaly the same motor i was just wondering if there is any other trick that i can try?

Dear All,
i have a A 14 motor that i have worked on a little but i cant get the rpm any thing above 6000, it was balanced, the head was ported and gas flowed, and i am running a 262 deg cam, lightend flywheel, and twin 40s!
Any Idea why i cant get higer rpm?

Thank you, i wil give it a try !!!!

Dear All,
I am looking for a solidmodel of a Datsun ute or an Datsun Gx, then i can start some
planning or if any body can give me an indication where to begin looking.


Any file format will do!!!
