It's really funny how people keep on writing things like this - not to 
have a dig at what Peter's written - he's on the money. What it comes 
down to is the odd-fire crank in the DeLorean engine is simply not 
suitable for turbocharging, and that is only at the top of a very long 
list of problems with turbocharging this engine.

Why else would the Renault 25 Turbo have such a massively re-engineered 
engine? The Renault Alpine A610 produces in excess of 400hp reliably 
from a 2.5l PRV-6 that mates to the exact same gearbox as the DeLorean. 
The engine is an enhanced and intercooled version of that in the R25 
Turbo, which can be found in scrapyards all over europe.

Why do people keep trying to reinvent the wheel with an enhanced 
original DMC PRV when so many are available just begging to be dropped 
in, have an exhaust made to fit, and bingo-splingo, a 400hp capable PRV 
in the back of your D?

The DMCH engine is about as good as you'll get without spending serious 
money on rebuilding and reengineering a stock engine.

Oh, and the 3.0l PRV used in cars like the Renault Espace and Citroen 
Xantia up until only a few short years ago can be tuned (at some 
expense) to 300-350hp. It will bolt right in.
