RE: WTB : 5 cyl. Turbo - 215hp

[Todd Phenneger <phen9461@uidaho.edu>]

Mike,
    No I am sure you have gotten many responses to your inquiry but I
will add mine.  No Audi motor makes 215hp.  You are probably thinking
about the 3B motor which is the 20v turbo that is in the 91' 200
quattros, S4's, and the S6.   This motor put out between 222 and 227 hp
depending on the application.
    THe other motor most commonly used is the MC code block which was
available from 1986 - 1990 on the Audi 5000 turbos, 5kt quattros, 200
and 200 quattro.  Stock the 89.5 - 90 MC is better with higher
compression (8.4:1) and a smaller K24 turbo that spools up much
faster.   For high boost applications I would think the earlier MC with
(7.8:1 ??) cr would be better but it has a primitive turbo design that
is not good for more than 300 hp.
    BTW, the 20v turbo on the newer cars also has a k24 turbo.
THe MC swap is much easier and can give ou 250hp fairly easily.  300 -
350 depending on how much you want to spend.  Talk to someone like NEd
Ritchie at Intended Acceleration if you are serious about modifying the
motor.  His Web page is  http://www.intendedacceleration.com/index.html.

    There are many other sources too that the list can provide you with
but this is who I am most familiar with and I know he is VERY
knowledgeable in this department.
    THe 20v turbo swap is much more involved and the initial price of
the motor will cost you about 3 times as much.    ($1,000  vs  $3,000
)   THat is for a used block i good condition but of course you may
stumble on a real find too.   The 20v motor is heavier but uses a
MOtronic Fuel Manegement system.  THis means the Mechanical part of
putting in the motor is easier as you dont have to bend a Tie-Rod to
make room for the Waste GAte, and you have lots of room where the MC has
its   CIS system.  The downside is that the wiring is much more
intensive than for the MC  motor.
    HOWEVER, both motors require major rewiring as they both need their
ECU and wiring harness added in and some connections spilced into the
main fuse box and Fuel Pump Relay.
    The 20v is good for 400+ hp without major work and is good for even
more with stronger cranks and reworked  head/cam/intake etc,.   Again,
talk to Ned as he has built a few 400+ hp cars.   BTW, with this much
power,  THe rustangs/camaroes/ or even Vette's will have trouble keeping
you in sight.  :)
    Glad to hear of another person attempting such a project and give me
a ring if you have any more simple questions.   L8R
    AND PLEASE,     UPGRADE THE  BRAKES AND SUSPENSION IF YOU DO THIS
CONVERSION FOR THE SAFETY OF THE CAR, YOURSELF, AND OTHERS.   :)

Hey guys -

We are looking for a engine to put in our 86 4000CS Quattro.. The 115hp
or
so just doesn't cut it when trying to keep up with american V8's..
  Sooo... I don't know much about the engine names.. So bear with me..
It is the 215hp Turbocharged 5 cyl. that was in the 89 (we think) to 91
cars.

Anyone that has done/attempted this that feels free to share your
thoughts,
please do!

Thanks
