I'm not sure about this, but I believe you can only do the 3.4 or 3.6 engine swap if you change your transmission also. You will need the Boxster "S" type trans. in order to get the 6 speed gear box. So if you have the 2.7L base model like me, you have to upgrade the trans and clutch too. Otherwise you have all that new power with no way to use it. You will also need a new CPU for the new engine. Can't use the 2.7L CPU codes on a 3.4 or 3.6. Unless they re-program it for you. Better brakes would also help, but bigger may not matter.
