Don't know a lot about A14's, but in a lot of engines you'd be getting close to the water jackets.

sounds good to me.

i live my life quarter mile at a time.

Hi Sparky

Great idea.
I am just a bit worried about your gearbox for drag racing. GX 4 speed does'nt say anything. As far as I know it is just a standard 4 speed and according to some guys on this website they are a bit weak.
See if you can put in a bakkie 5 speed. Willing to pull 500kg on the back tells me it will be willing to do the 1/4 mile.
Otherwise sounds great.
If you want, I can PM you Minnesh's number so that you can get some more ideas for your GX.
He was in one of those Speed & Sound issues with that quick naturally aspirated A14 powered Datsun 4 door sedan.
Something like 13.8 seconds 1/4 mile in Durban.
Let me know.

Hallo there,
Getting to the gearbox, the Bakkie gearbox is strong but i blew mine around 200km/h.
same sort of spec as below,
just be sure there is enough oil in there( you must over fill it ) 1200GXman gan you please send me that Number?????

Cheers Sakkie,

is it going to be a drag car or a shopping trolley?
wheres the turbo,or nitrous?hell,its not even a v8.

yerr i agree with dat383, circuit car maybe?

I am not a great fan of turbo and stuff,sure they make alot of power but anyone with the money can have a fast turbo car.
Having a normally asperated thats really strong takes some brain power!

An NA A series can be a great little performer but they are not going to set the world on fire as a drag racing motor.
