I have managed to find an A-14 which has been put into a sunny wagon. Any way what is the best way to get these motors to perform and rev hard.
Couple of sugestions i have heard (can you tell if it works or is it just a load of crap)

Bolt A-12 head onto A-14 block (high
compression) can it be done

Use A15 crank rods and pistons machined to fit A14 block again can it be done

You tell me what is the best formula is to get power out of these little beast motors

Cheers Josh

well i am getting a fully rebuilt A14 with a flowed and ported a12GX head, and i has a potential of 123hp at the flywheel, and that is with a econmical port job

yeah from what i have been told a A14 block with A15 crank rods and rb26 pistons shaved off (is this right people rb26 pistons can be used?) .... and a gx head, will give good peformance and power.

a guy up here runs a A14block, A15 crank forgie pistons GX head etc etc big fuel injection system and is getting 168hp....

p.s people i will be getting photos of this engine fuel injection motor this weekend, as long as the guy is running in the hillclimb

Thats 80mm RB20DET pistons not RB 26.
They are cam ground back to 78.5mm

How much would it cost for these rb20 slugs modded for the a14 running an a15 crank??

Hey yes pls show us those pics when you get em.

Seems to depend on the mood of the piston maker????????

I have been quoted $350 for the four pistons (plus initial purchase price). I will keep the club informed of the success or other wise of the mods.

These slugs r the forged items??
I hope they work out.
