Failure of Superchaged Z and Cosworth rebuild

[TDI]

This supercharged engine suffered a catastrophic failure at an indicated 195 MPH in 6th gear with the techo needle bouncing off the rev limiter

 

Pieces of the connecting rods are still spread over some Belgian tarmac I believe

 

Here's what happens to the cylinder block when a connecting rod parts company.

And here is what used to be a connecting rod

so you mean this engine has gone pop with an HKS SC and cossie internals?????

No, the engine was standard but is now being uprated with Cosworth internals . Sorry for any confusion

[TDI]

Here's a picture of a Cosworth low compression forged piston undergoing the balancing checking process.

 

These are very strong and are ideally suited to engines with a supercharger or turbocharger.

 

The piston skirts have a super slippery anti-scuff coating too

These are the Cosworth/Carillo H section forged steel connecting rods fitted to the Cosworth pistons.

 

Please note the design of the underside reinforcement of the pistons.

Here you can see the cylinder block partially assembled, showing the Cosworth piston crowns, Cosworth cylinder head studs and metal cylinder head gaskets.

This picture shows the cylinder block assembled with one cylinder head/camshaft assembly almost complete.

This picure shows the engine mostly assembled, without the anciliaries etc.

This picture shows the engine fully assembled, with the ancilliaries and HKS/Rotrex supercharger, on the trolley on it's way to being reinstalled in the car.

Here's a close up picture of the Rotrex supercharger

Here's another picture prior to engine refit

Here is the engine bay prior to engine refit

Here is the front of the 350Z without the nose cone, showing the intercooler.

Here's the engine safely back in it's rightful home.
