Hi ? (you don't sign with your name?)

I think your attitude is commendable. It's so easy for people to put 
their hands of their ears and go "la la la la" :-) It's nice to know 
you're taking this stuff seriously. It certainly sounds like an 
excellent place to start as long as you don't pay too much for it based 
on these claims, and I've always been keen to see what a 3 litre 
odd-fire would do. But the 3 litre engines have a fair amount more 
differences than just 126cc (2975cc - 2849cc).. That said a standard 
Renault Safrane engine puts out only 170hp at the flywheel (catted and 
restrictive exhaust and tuned for torque) - this was the ultimate 
evolution of the naturally asp 12v PRV. It has higher lift cams (albeit 
with hydraulic tappets), considerably larger valves (it's valve 
circumference that makes the difference, not x-sec area) fatter pistons 
and the same stroke as a DeLorean engine. Your engine must be running 
stock heads because the DeLorean intake manifold has to have adapter 
plates made in order to mount to the 3 litre heads (the ports are higher 
up) not to mention not having the injector ports.

The exhaust bolts right up. This is the approach I took doing this 
Renault Alpine which began life as a GTA Atmo (ie naturally aspirated - 
essentially a DeLorean engine with carbs)

The exhaust is an aftermarket one that came with the car. We're 
installing a custom ECU and I hope to breach 200hp given a better 
exhaust and no emissions worries! That is a completely standard Safrane 
engine that originally came from our courtesy car.
