3.4 or 3.6 Conversions?

I'm thinking ahead just a bit, as my 2.7 still runs nicely. But when the day comes when it's time to retire the tired old friend, I'm thinking that it's time to really consider an upgrade to a 3.4 or 3.6. RUF will do a 3.6 conversion, but they want to sell me the entire RUF upgrade which is nearly $30K (I don't really like their wheels or body kit).

Other things to consider, what else would need to be upgraded? Brakes? Suspension? Also, who are the reputable shops that will do the conversion?

Those that have done this, please chime in.

Thanks,

Jeff

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.

I've got a tiptronic so that shouldn't be much of an issue. I know, I know, but in a major metropolitan area with heavy traffic, a tip can be a welcome way to cruise. Plus, once you get the hang of the steering wheel shifters, it can almost be as much fun as a standard transmission.

Having a tiptronic does not necessarily mean that I squat to pee.

But even with the tiptronic, you still only have 5 gears with the 2.7L. The 6th gear would still be required weather you have an auto or manual.

There are 996's with 3.4's and a 5 speed tiptronic. So I don't think that a 6th gear is required.

If that is true, then you got me. Sounds like it's posible with your car to do then. I would definately upgrade the clutch, CPU and brakes then. Good luck if you decide to do this mod.
