Look up Flat 6 Innovations. They have a range of options around this as well as LN Engineering

ttt123

they are just as expensive

My Vision built 4.0L was ~$25k. It is a race built blue printed engine with all the good internal parts. Mine was low compression for turbo so I have no idea what the NA wheel HP was, however the NA 4.0L in another Vision race car did an easy 360 wheel HP on 91 octane. It could have done more but class restrictions for weight to hp resulted in a tune that rolled off top end power. For the street a 4.0L makes a great difference because there is a fat torque increase across the entire rev range.

ttt123

nice. Did they do the tune as well. Did you supply the motor or them?

thanks

My engine was trashed. The heads and X51 intake where reused . 3.4L blocks usually can't be bored out to 4.0L. A used 3.8L block and crank from Visions used stock got the job done. All accessories where reused. Vision did the tuning on the stock ECU. For the M97 race turbo and the NA 4.0L M97 AEM ECU. My 836 WHP TT Mezger is Motec tuned by Shane Tech.

thanks for sharing. Im trying to explore all options.

Go turbo. If done right, you won't look back. Just manage the intake temps and don't run more than 5 /5.5psi on a stock motor. Use a good quality air / water cooler and / or a good boost controlled water / meth injection kit.

My son's car should be back together in a few weeks. I can email you a couple of vids if you'd like.

ttt123

I would love that. Pm and i can give you my email. Im willing to make upgrades to this motor (2.7) if needed for whatever route i go. I just need to pick one

thanks

There is a UK company making a 987 Twin Turbo kit, going to be released early next year ;-)

ttt123

Might be a bit longer than anticipated now. Going to get a new turbo and fab up an intercooler. I will however let you know when it's done.
