Here is what I know:

The 3.2 uses a head nearly identical to the 3.4

The 3.4 makes 300hp stock

The 3.2 makes 250hp stock

Porsche CUTS THE NUTS off of the Cayman's and the Boxster's

If I use the same size exhaust and cats from a 3.4/3.6 on a 3.2 and utilize a 3.4 Cayman Airbox and a 3.4 sized throttle body, I *should* be able to make 300hp out of the 3.2 engine without compromising anything. We have already made 250 with a 2.7 with little to no mods.

3.4 has the 3.2 crank with just smaller pistons in the 3.2
3.4/3.2 cams are identical.. (they say 3.2/3.4 on them)

I have the 3.2 car I'm going to test all of this on, and I have a base tune ready for the car based on a 3.4 tune.

As some of you dig in deeper to the ECU's you are going to see the BIG cam timing difference between a 3.4 996 tune and a 3.2 986 tune. Then again with the 3.4 CaymanS tune and the 3.6 996 tune.

From a manufacturing standpoint.. they will only cast a few parts.

CaymanS 3.4 uses 3.6 heads.... (they actually say 3.4/3.6 on them)

So? why would a 3.4CaymanS only make 300hp? when the 3.6 makes 350? (Porsche cuts the nuts off the mid engine cars)

Just thinking out loud. You may have to consider the merits of the 3.4 intake runner and plenum (left and right) acoustic properties to get the 3.2 to breathe.

Brad,

How are you getting 250 HP from a 2.7 with little to no mods? I
have a 2001 and I feel like a moving pylon at the DEs against all the Caymans and 996s in my run group.

Thanks
