[DML] Turbo PRV.

[Marc Levy <malevy_nj@xxxxxxxxx>]

I think if there was a reliable modest way to gain
power, we would *ALL* have done it already.  With that
said, you can go ahead and change the pistons and rods
in your PRV and bolt up the turbos.  You will probably
like the end result, but it sure would suck to blow
the engine up after you have spent all of that money. 
I have considered doing this myself a number of times,
especially because I already have the Island setup...
But always go back to the point where I ask why I
would spend so much money on 30 year old technology?

I am not taunting anyone.  I am not a turbo expert by
any means, heck I am barley a turbo amateur!  I know
just what I have learned about turbos (on the DeLorean
only) from talking to people like Rob and Fred about
it.  If you have the cash to spend on a Hi-Po PRV,
give John Lane a call.  He seems to be *THE* north
American PRV expert.  

Based on what I saw, the designs were similar.  The
Alpine (310's I think) were fitted with the Twin Turbo
engine, similar to what is currently in 502 and 1860.

There were some pictures Fred had of other concepts,
but they were all foam mock ups of possible manifolds
and component layout.

Best of my knowledge, the only configurations Legend
built were the twin turbo (502) and a single turbo
(528). The single turbo came AFTER the twin turbo in
an effort to reduce the cost.  Although I have spent
time looking over 528, I have never heard it run so I
don't know if it was a stock PRV with turbos bolted
on, or it was a modified PRV with just the one turbo
instead of 2.  

The Legend engines do not run as quiet at the stock
PRV.  You can hear some piston slap. 

As far as specific answers to your questions (sourcing
parts, and such), My plan would be to rebuild your PRV
using parts from a Alpine, or maybe even a Venturi. 
Those pistons/rings/rods/head gaskets all worked well
with forced induction..  Legend had planned on a
electronic boost control (I think 502 has this), but
1860 has a vacuum based control with a threaded rod to
adjust the waste gate (My guess is this is how they
dyno-tested the engines).
