2007 Cayman - 4.2L swap

Instagram: @cruisin_for_causes 

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. :)

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:

• 997S 3.8 Donor Motor, fully disassembled, inspected, cleaned, measured.
• LN IMS retrofit; gear welded to the shaft
• New water pump; main and rod bearings
• Original crank knife-edge and machined 
• Carrillo rods and bolts
• Oil pump housing ported and polished
• New oil cooler
• 103 MM JE Pistons
• LN sleeves
• Motorsports AOS

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:

• Full disassembly, inspection, cleaning, extensive measuring, etc.
• 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)
• Custom aluminum Bodymotion 3 quart deep sump + pan ($4,000)

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

• 19x8.5 Varro VD38X Gloss Black (Spin Forged) 5x130+
• 19x9.5 Varro VD38X Gloss Black (Spin Forged)5x130+
• 235/35/19 Pirelli P Zero
• 285/30/19 Pirelli P Zero

The car serves as an icon for my charity, Mayhem Raving Charities. We raise money via road rallies, car meets, etc and make sure to create a positive image for the car community. If we want to keep our hobby around, we need to ensure we give our communities a reason to want us around and that's really our mission with it. Help improve our direct communities with the power of cars and enthusiasts.
