Dave Lowery - 2007 Cayman - 4.2L swap
The motor retains the basic blueprint of the original VISION build, which is largely a mix of the same methodology and materials used by every other reputable M96-97 big motor builder (LN, Raby, BGB). However, on rebuild, Memphis Motorwerks has gone a bit further to address potential weakness and common issues with higher displacement M96-97 motors. The original build details and enhancements are as follows:

2007 Cayman - 4.2L swap

The original plan was to swap it down the road if something major failed....keyword "original". Two weeks after buying the car, my buddy sent me a link to a fully built 3.8 from a 997 S. Bored to a 4.2, deep sump, x51, pistons, rods, sleeves, etc and it was already set up for a 987.1. How could I say no?
The seller and I worked out a deal and set up shipping. The engine arrived and my friend, Tobi Connell, did the swap for me. A 4.2 from a base 2.7 is a NICE upgrade. :)

This was VISION's most extensive "full track" package. The cost for that build was $31,000, WITHOUT intake, sump, or exhaust components, and of course without install or shipping. On rebuild, Memphis Motorwerks has done the following:

- New OE 3.8 crank (NO cutting or machining)
- New OE harmonic balancer*
- New OE oil pump and cooler (precaution to ensure no debris from failure)
- Full set of new JE pistons (precautionary ~ $5,500)
- One Carillo rod replaced
- New timing chain, cam chain, and chain guides (precautionary)
- New IMS using LN's methodology of removing inner grease seal (https://imsretrofit.com/my06-08/)
- #3 cylinder re-sleeved with LN sleeve
- New intake valves and all valve seats refinished using CNC machining
- Full X51 intake + GT3 throttle body (~ $6,000)

For suspension, it's on H&R coilovers and rolling on 19" wheels.
