Question
Hi!
I am trying to find as much info on how to go about converting a 968
sport coupe to a turbo.
What are the pros and cons?
What percentage increase could be achieved?
How will it affect reliability?
Can the chassis/suspension take the increase in power?
Thanks
Question
I am from the US and was wondering did Europe get
a 968 Turbo or Turbo S. Is there a kit or some sort to upgrade a US
968 to convert it to a Turbo model?
Thanks for any info,
Answer
Hiya
Don't even bother trying to Turbocharge you 968
engine, the hassle time and
money out way the costs
Your best bet is to source a good 944 Turbo engine and transplant this
into
your Car, its completely a straight swap.
install an dual port waste gate, a replacement Garret turbo unit. An
air
induction kit and stainless performance exhaust, and voila, 300+ bhp.
If you want to get it chipped and a MAF air flow unit as well, then
you can
be looking at 315 - 325 BHP is that enough for you
Go for it
Answer
It is possible and not too expensive to convert
a std 968 to turbo S specification.
We are presently conducting just such an exercise and the engine has
been built and is presently ready to go back in the test car. Once it
has been proven we will reveal the results and costs etc. However the
process of working on the conversion has revealed many interesting points
and bits of miss-information that has been trotting around the internet
and various books etc.
We think we have worked out how Porsche did it and what parts they used
and we only had to manufacture one component and modify another to put
it all together using parts from basically 3 different engine types
- bolted together - so comparatively unspecialised and relatively inexpensive
if access to some used spares is not a problem - with replacement parts
already available world wide.
I prefer the idea of a 3 litre turbo running at a lower boost than trying
to get the same output from a 2.5 litre engine with more boost because
the drivability of the car under acceleration is the most important
feature for me and there is not as much weight over the driven wheels
as for a 911 variant - so a smooth increase in torque from low revs
is more important than a sudden huge boost of torque at higher revs.
By retaining a std turbo charger and boost we expect 300+bhp but a much
smoother torque curve. Of course extra boost would make thie engine
extremely powerful.
I hope that this might make the ultimate front engined Porsche - but
only time will tell.
Because we are so busy at present it may take a few months before more
is revealed but I am hopeful that it will be worth waiting for.
