Turning up the boost is a free option. fit a boost guage with 1psi incrememnts and set it to 9psi using a mechanical boost controller.

you can run 12psi no preoblem but it will involve canging your spark plugs and there gaps and possibly adjusting your timing. A reeer flowing air filter and removing the s12s centre silencer and changing the rear box are also cheap ways to get good power gains. a 35bhp increase over standard is quite easily achievable for peanuts

for the auto-manual conversion you will need to fabricate a gearbox mount and use the prop that comes with the manual box as the auto/manual/mk1/mk2 have different lengths i think they may have different rads as well, as the auto prob needs a oil cooler
its not too hard, but unless its a low mileage rust free minter i would sell it and get a manual

i've got a mk2 auto in white, its very tidy, thats the only reason that i'am doing the conversion, the pedal box is a right tawt to get out.
