All motors could require minor modifications for install (drill and tap holes or clearancing). These changes are minor and can be performed with simple common tools. Thompson Motorsports is not responsible for the work required nor does this warrant a reason for the return of the product, even in the case of a direct replacement. We are dedicated to customer service and are more than happy to help with the install in any way possible. Please feel free to call or email with any questions or concerns.
All high performance motors will come with no VVTI or DOD. If the vehicle originally had either or both of these you will need to change to a LS2 front cover and LS2 valley cover to eliminate. You will also need to alert your tuner to the changes for PCM changes.
