I have been spending a lot of time investigating all of the performance PRV-V6 motors, and this is a turbocharged motor. The performance tune on this motor is from the addition of a turbo. The pistons are lower compression than the DeLorean, so they can increase the boost over what our aftermarket DeLorean kits are limited too. Although I do not have details on the differences between the A610 cam's and the DeLorean, I dont think this swap will be any improvement.. The A610 is rare, and I was in the process of trying to purchase and import one of the motors. Most of the leads I got with claims of a A610 motor were actually A310 Turbo, or other similar renault turbo engines. On closer inspection, the configuration of those motors will not fit in the DeLorean without heavy modification to the turbo plumbing. Sad things is, Most of the high performance cars that used the PRV-V6 motors are considered rare.

It was equipped with a Garrett T-3 turbocharger and produced 250 hp. I would assume that it had a "performance" cam and that such cam might very well work in the D engine. Anyone know anymore about this? Dick Ryan VIN 16867
