Why must there always be the onslaught of OMG BEWST PWNZORZ ALLMOTO.
Most people know this he stated he was looking for all motor gains. I know your all trying to help but its like if I walked into Burger King made an order and you told me you know there is a great steak house down the street.
Slow99 gave some great ideas for gains for 1500 total i'd look into that head I linked you too and cams or you can look into F/I as brought up before a vtec head swap might also be nice some good gains cheap now and will help N/A or F/I setups heck that might be all you want and call it a day even.
Last thing, if you ditch the axle back get a full catback exhaust free up some power for you.
