Surely the cost would outweigh the benifits here? Whats your options?
* keep the 276hp engine and mod it up to 310
* put a super carger onto the engine keeping standard internals 380ish
* put a super charger / turbo onto the engine changing the standard internal and aim for the stars
* swap out the engine to a HR one and get 313
On paper I know what I would do... but cost, time, insurance etc would probably change it...
The Q to ask and answer really is this >>> What do you want to get out of this?
One thing to remember, I didn't get modding to save money or expect to get any of it back if I sell up...the more mods going in though the less likely that I'll sell in the first place
