Tassie,

Heed the advice of several on here; build it for what you want to use it for.

Clearly identify the use intended - then considering cost and rego requirements, pick the engine that fits. There may be a few options here but this will narrow it down somewhat.

If you're asking the question "which engine" then you must have no preconceived desires. Keep it simple.

an LSA or LS9 will give you more power than you can use in these cars without a good traction control system. I went for a run in a work mates new GTS last week and it was just insane - 430kW LSA I think. If it didn't employ all the latest driver aids, I don't know if I'd be here writing this. My point is don't get hooked on bigger is better. What suits and what is easily registrable, is better.

In Aus the kit brand or build quality will affect the resale more so than the engine choice, but the car should ultimately be what you want, not what the next guy wants.
