HDDP, are you only concern about the engine? Or the look and body too?
Because I can help with the body, I Know the right company if we want to get a full body kit design for $675+ shipping and a xfire from California gets it free see below:

Custom Body Kits.

START A GROUP BUY FOR A CUSTOM BODY KIT
WE CAN MAKE ANY STYLE KIT FOR ANY CAR...

That's right, we make custom body kit (s) for any car, and any style you choose, we are a body kit and spoiler manufacturer. Your shop, or you can start a group buy on any message boards/groups, and the original starter who organizes the group buy, and decides on a style body kit, it could be any style, will get a really good deal on their kit for their car.

Info on the custom kit:

1. Each group buy has to be the same style kit, and the same years.
2. All we need is 10 pre-orders of the same custom kit you choose $675.00 x 10 people with the same car, and want the same design kit (that is a complete kit!) add shipping is paid upon delivery FREIGHT COLLECT. (you don't pay for shipping upfront, you pay for shipping when your kit arrives) we would need to ship to a business address (any business address will do, like your work, or a body shop).
3. After we get the pre-orders, we would need a sponsor car to prototype the kit on in CALIFORNIA, of course the sponsor car will get a FREE Kit, but first we would need the pre-orders and the group buy organized and pre-paid before hand. (please do not email us for sponsorships for this).
4. After the group buy is complete, allow 5-7 weeks for us to make the kit, and we can ship the kits our after. We do not make custom kits for one car. we only make custom kits for group buys of 10 orders minimum. Email us for inquiries regarding group buys for a custom design body kit).
