Julian's Astra Van | |
| This is also one of our own cars. This is a case of a car we got carried away with... |  |
 |
The van is used mainly for spiriting and actually started of as 1300cc builders van and went through various engine changes until we settled on using the 2 litre twin cam engine from an Astra GTE. The v an was competitive but we felt it needed a little bit more so with the help of a local engineer we developed our own turbo conversion using a garret turbocharger from a metro! |
| We also fabricated our own inlet and exhaust manifolds as well as a lot of the pipework and bracketry. To obtain the compression ratio required for turbo charging a stainless steel spacer is used between 2 head gaskets, we chose to do it this way rather than have the pistons machined because if anything dm go wrong with the engine internals we could rebuild it with parts off of the shelf rather than have to wait for parts to be re-machined. As you can imagine this made the van a bit of a surprise to the unsuspecting performance car owner and the odd motorbike. |
