A Series Engine stories..

Recommended Posts

So, we all know the beloved A series.. the under-powered piece of cast iron that moves our rust-buckets. And for those of us who've owned them, we know they are virtually indestructible. My Old man gives me a hard time for revving to 5k, most times I drive it. Does anyone have any stories of doing this regularly and killing the motor? His reply to my driving tonight... "You're damn lucky it's a datsun."

If in good shape and filled with oil and not allowed to overheat they can sit at 5K all day. It has FIVE main bearings supporting the crank!!! If anything like the L series the bearings were way oversize on the rods.

She's in good shape! Sitting maybe a half a quart low. Almost time to change it anyway. Never let it overheat. Don't let the temp gauge run far past half (roughly 5/8ths). And damn, I didn't know about the bearings...

i hit 6200 and floated valves in mine all the time. overheated it on the daily too. i just ran synthetic and kept an eye on the oil pressure. mine never dropped below 45 at anything over 1500 rpms. my regular shift point was 3.5-4k in my auto.

Search youtube for NZ Ministocks (cant access youtube at work to post a link). A12 powered dirt track cars that 12-16 year olds race.

Slap it in 2nd and plant your foot. Great fun.

I have run my A12 about 400 miles around 4500 to 5500 rpm worked like a charm. Years ago ( and buddy I mean YEARS) I tried to blow up  an A12 motor...couldn't do it.

Cool story: Before I rebuilt my A14 she was running on only 2 1/2 cylinders but still getting 30mpg. Funny/D'oh story. After I (thought) I finished the rebuild, I discovered a pile of long thin cylindrical pieces of metal. I'd forgotten the pushrods. ::Facepalm::
