Porsche engine options (long)

["d_rex_2002" <rich@xxxx>]

Porsche engines in Deloreans are feasible, but you need to look into
exactly what you want to accomplish and find the best donor for your
needs. To better define what will fit easy and what will require the
6 foot shoe horn to get it to fit, let's look at the Porsche options.

To further clarify the Porsche engine options, the 911 series engine
including early 911's and later 964, 993, 996 and Boxster 986 series
are all horizontally opposed flat 6's, which vary from 150hp to up to
and exceeding 300hp in normally aspirated OEM stock configurations.
The main difficulty with this type of engine is the width, not the
length, to attempt to fit this engine in a stock Delorean engine bay.

As for the 944 engine options, the early 2.5L 8 valve 944 engines
produce between 145hp ('83) through about 165hp ('88) for the normally
aspirated engine and in excess of 300hp for a 'tweeked' turbo setup.
The later 2.7L models (in 944 S) produced a few more usable HP, but it
was not until the 3.0L 16 valve models in the 944 S2 that the normally
aspirated model exceeded 200hp. The best of this line was the '92-'95
models of the 968, with the 3.0L vario-cam setup producing 232hp in
normally aspirated form and over 450hp in the turbo Club Sport model.

The 944 series engine is an inline 4 cylinder, which was designed as
half of the 928 V8 engine, so it sits on a 'slant' in the engine bay.
It uses counter-rotating balance shafts (they wheigh about 3 lbs) to
keep the engine from running rough, and it's a very smooth setup.
This engine will fit into the Delorean engine bay without major mods.
The best 'bang for the buck' would be a 944 S2 engine (over 200hp)
since there are no turbo 'plumbing' issues regading sufficient cooling
and the reduced engine weight would better balance the distribution of
the overall car weight to about 40/60 from 35/65, depending on the
transmission selected.

As for the Porsche 928 V8 engine, this is an aluminum block V8 ranging
from early 4.5L with 220hp (US) and 300hp (Euro spec) to the later
model 5.4L with 345hp (using the same external dimension size block).
Although this is an aluminum block engine, it is by no means lighter
than Ford or Chevy V8 engines. Although one of my projects may use a
early 928 S4 5.0L V8 engine with 320hp, I do not have the measuremants
finished to identify how much of the Delorean engine bay will require
modifications (and obvious reinforcement).

Porsche transmission options I will leave for another discussion.
