This thread has been split out from my 2001 project car thread, as although it is all part of the same grand plan in terms of engine development, it isn't really anything to do with that particular project.
This part of the project involves buying in a full Boxster 3.2l engine, seeing which ancillaries are the same as the 3.4l M96.01 engine so that I can use those for checking clearances, and then have the rest of the engine rebuilt as a 3.7l engine for my C2. The thinking behind this is as follows:
1/ The overall project aim is to develop 3 sets of camshafts for different engine specs, so it makes sense to build up three engines. We already have two lined up, so this one will be the most 'base' spec of the three.
2/ A 3.2l Boxster engine can be had MUCH more cheaply than a good 3.4l 996 engine. It produces less torque and power so is less likely to have internal wear issues, and it shares the same block, heads, crankshaft and camshafts, which will all be used.
3/ As the block is being bored out anyway, the fact that the Boxster runs smaller pistons is of no consequence.[/list]
I heard the engine running before it was pulled so hopefully no bad suprises in store.
