LN 3.2 to 3.6

[The Radium King]

hello - has anyone doe the LN Engineering 3.2 to 3.6 bore increase without any other revisions to the engine? that is, Jake Raby also does valves, cams, ecu, oil plugs, etc., as part of his conversion - is this required, or can you just increase the bore and let the ecu compensate as per the LN website? i've heard headers are a real benefit, but are any other intake mods required (injectors, etc.)? i realise that any mods done in conjunction with the bore increase will increase hp/torque, but are any NECESSARY to accompany the bore increase? or, are do any of them provide an ok 'hp:$' ratio? i ask as a Raby stage i engine is over $15k, but the LN bore is only $4k. i'm sure that that additional work Jake does increases hp and longevity, but i'm trying to get a feel for where the law of diminishing returns kicks in (probably when i first bought the car ...).

thanks.
