VK Swap Discussion...

bullitt5897

So I have been contemplating the idea of using the latest VK v8 in a swap. The motors can be had for cheaper than our VHR motors...

My Ideal setup:

De-Bored VK56VD from 5.6L to 4.8L block with lightweight forged internals. By doing this we have effectively made a squared v8 @ 92 Bore and 92 stroke... A very potent combination! This will give us the strongest v8 possible. Personally, I would want a high compression 12.1~13.0:1 compression ratio and 9,000 RPM red line.

Optional: Flat Plane Crank shaft... What this would do would even out the exhaust pulses and effectively make the motor act as two I4's strapped together... Which means you would have a lighter assembly which revs faster, a larger power band, and a very unique sound geared to sound similar to a formula 1 style car in higher RPM's.




Why the VK56VD?: This is the latest version of the VK motor which supports both Direct Injection and VVEL! This would be the closest VK motor to a direct swap that hopefully in theory we could keep our ECU....

Why De-Bore?: Toyota and many others have proven that a squared setup between bore and stroke produces the strongest motors... Whether it is N/A or FI a Squared motor is going to be the most reliable.

Why High Compression?: Because RACECAR!

Why 9,000 RPM?: See Above ^^^ lol also a broader RPM range gives us more room to work with on the motor. Would a De-Bored aka "Sleeved" motor make it to 9,000 rpm? I dont know... It would be fun to try though!

Why Flat Plane Crank?: Ferrari and many other exotic v8 cars have used this technology and have had impressive results with it. Remember the 458 Italia???? some argue is the best production v8 of all time... Lets hear that bad boy scream!




What are your thoughts on the subject?
