Motor swap options????

[986speedster]

Everyone talks about upgrading or supercharging, turbos..... What is the largest motor one could swap into a Box? If I had the money to buy a 997 3.6 twin turbo, could I have it installed, or is there a size limit?

I would rather do a 996 GT3 motor!

Right now, into the 986, the largest displacement that is a pretty straightforward swap is the 3.6L from the 996. I believe there are a couple 986 boxsters out there with the 997 3.8L, but that is a pretty extreme and involved swap. The 987 boxster can get away with the 3.8L from the 997. You could go pretty large...and could always go big bore on a 3.6L and make it a 4.0L or even larger.. the motor itself is the same size... just playing around with the internals to get a bigger displacement

One of the size limitations with either the turbo motor or the GT3 motor is the external oil sump that these motors use. Flipped around for use in a Boxster, the oil sump would be on the left rear of the engine. The wall into our trunk is in the way. A possible solution would b to fabricate a sump similar to the coolant tank on the opposite side and plumb it in. I would absolutely love to see a Boxster with all the GT3 bits, including the motor. THAT would be an amazing automobile!

The only limitation is how much $$ you have to spend.
Unlike what is mentioned below, it is no more complicated to put a 3.8 into a car than a 3.6. And no more complicated to put a 3.6 into a 2002-on car than a 3.4 into the earlier cars. It is when you start crossing the boundaries it gets complicated.

Try the search function, these questions have been answered several times.

Can the exhaust components from a 3.2 be used on the 3.4? ECU?

I know the question of putting regular 3.2, 3.4 or 3.6 have been answered in the past. I was asking specifically about the turbo motors. Thank you to everyone else who understood my question.
