Hi.

I'm just want some tips on how to get more effect out of a B27 RPV engine;-
what's the quickest and easiest way
to do this?

Thanx in advance

Well, I pulled mine out and fitted a 350 chev instead. :-)

In all seriousness, the first thing to do is make sure that everything
is there and working properly, including the air intake duct from in
front of the radiator, which seems to vanish on cars in Australia...

The _first_ job should be to pull the fuel distributor, etc. off the
top of the engine and service the ignition system fully. I'd put a
new rotor, cap and leads on simply because it is such a painful job
to do - fit new bits while it is apart...

Had this motor in two Peugeot 604s. Both blew up. Never again

I put the first one on LPG (removed the Volvo injection system) and
got it to last 2 years - it then did a bottom bore seal and filled
the sump with coolant.

In the meantime, I'd _sold_ a '78 engine to a Pug guy "as is" with
an apparent blown head gasket (it was half way out of the car when
I bought it) for $50. When I pulled the running but water-in-sump
engine out to put the 350 in, I _gave_ the second engine including
a modified intake that cost me $50 in TIG work to the same guy.

Now, the same guy is going to _buy_ a running B28 from the '82 265
I bought recently for parts - He's offered $200 and the engine is
about 12 hours from being out of the car...

This guy has a PRV in a 504 (?) with a turbo and running LPG...

Quickest and easiest is probably to swap in a better engine, the PRV's,
particularly earlier ones had problems being reliable in a stock
configuration, start cranking up the power and it'll likely fall apart. If
you started out with a newer B28 you'd likely have better luck, but overall
that's not a very good motor for high performance.

Renault made a light iron block for F1 racing based on the aluminum
motor. The iron block was stronger and more suitable as a suspension
component in the stressed motor configuration. Fitted with the Gordini
four valve heads it can be configured to various displacements and
horsepower. The 1.5L F1 qualifying turbo motor in the late '70's made in
excess of 750 hp. The 2.3L Alpine turbo version did somewhat better.

The PRV engine has a bad name only because mecanics do not know how to do
regular repair jobs on the engine.
In order to be succesful you need to think french.

It has a bad name because it needs regular repair and rigorous maintenance,
whereas the 4 cyls are bomb proof and run reasonably well and for many miles
with bad maintenance.
 
Hey we are talking PRV V6 motor here not four cylinder "tiny" motors LOL. The
B27 is 2.7 Litres of V6 with a poor reputation for the oil feed to the
camshafts. The later B28 (also V6) suffered from a similar problem while the
B280 was free of such problems. The B280 was used in Renault, Peugeot and Volvo
cars and was also the motive power for the DeLorean. If you want to up the
useful power from one of these V6s then choose the B280 and if possible one from
Peugeot or Renault as these were available with turbo and intercooler.

Cheers, Peter.

Unfortunately for DeLorean the B280 motor wasn't invented yet. They had
the standard B27 with K jet. Volvo did the head redesign for the B280 and
solved most of the lubrication and metallurgical problems that plagued
the earlier versions. It's really not the same motor at all in terms of
reliability and performance.

Are you sure about this? Everything else I've read says the DeLorean
came with "US emission-controlled version of the Volvo B28 engine".
It is K-jet fuel injected, and the displacement is 2849 cc, which would
also suggest B28 and not B27.

But in either case, as you said, it _definitely_ was not B280. Heck,
they stopped making DeLoreans _long_ before the B280 came on the scene.

I think you're right, the Delorean used a B28, although the engine was
actually bought from Renault, not Volvo. And for the purposes of this
argument (durability) the B28 and B27 are identical.

The DeLorean that was built (assembled) in Northern Ireland had a B280E motor.

Cheers, Peter.
