912 Engine Project Part 2

 

It takes some time to have all parts together for a nice build Porsche 912 Engine.

This engine will have it all.....

 

The 912 Crankshaft after polishing looks nice

 

the new lifter where checked for the cambered surface

 

Looks good!

 

The Lifters are all in tolerance but I like to pair it with the rigth lifter bore

 

New JE Pistons, 2g difference that`s too much for me.

I`m a little disappointed about that, because a high price piston like that should be better in tolerance.

Anyway I brought it to 0,2g ;-)  

 

 

AA Cylinder: Measuring the length, the Ø and out of round all where perfect :-)

 

Backlash and axial endplay of the Camshaft

 

Good fit of the Rods!

 

Dial in the WEBCAM Camshaft

The quality and finish of WEBCAM is very good

 

 

Just to compare:

 left 912 Pushrod

mittle JPS custom Pushrod for this engine

and the VW Typ1 stock

 

The weigth of 8 Stock 912 pushrods :-(

That`s too much in weigth and they where too long too!

 

Ah, 202g ligther than stock!!

JPS Aircooled Aluminium Pushrods for Porsche 912 Engine, you have the correct geometry with the rigth length and reduction in weigth too.

 

Win win!  

 

 

 

The combustion chamber after masching!

On Porsche 356 and 912 engines the combustion chamber are not equal you have to fix all
