here is the thing: a genV is and always will be more efficient than a genIII. a fully ported genIII will be cheaper than a genV and will get you pretty far. a blower swap is usually the last thing people end up doing to their car. on a full out cam build with an intercooler when someone swaps they will usually pick up between 15-20 whp because of the blower. on a more mildly modded car this will not be the case and youll be lucky to see 10 whp out of it.
if youre not looking to go mega fast its not really worth the money.
