no one makes a supercharger kit for the NG engine. It will be up to you to

Actually, I have the 'NG' engine. The 1988 Audi 90 Quattro came with
the 2.3L, not 2.2L, hence the dilemma with the A/C. If a turbo won't
work, even with a custom down pipe, I would be willing to lose the power
steering assembly in order to install a supercharger system.
Unfortunately, I haven't been able to find a kit for that app, either,
and a custom supercharger kit would cost almost twice what I have to

I have not done this per se, but I've been involved with a few
upgrades such as this.
Your engine is an Audi 2.2 liter Inline 5.
You will likely want to do an engine swap, but you'll keep your A/C (I
can see why you want the A/C in SC, I visit there from Seattle from
The engine that gives you the most bang for the buck, and is a easy
mechanical swap is the Audi MC engine code turbo I5. It's from the
1986-1988 Audi 5000 turbo quattro. It is mostly a direct replacement
for your current engine, with the turbo goodies, and some helpful
internal improvements such as oil sprayers on the pistons to help with
There are people who have bolted on the turbo goodies to the non-turbo
engine, so that is an option, but the MC swap will likely be more
Now, in the old days, the hard part of such a swap was moving the
engine management system. That involved stripping the wiring harness,
ECU and various sensors out of the donor car, and cobbling it together
into the recipient. It was a daunting task. Today, however, you
wouldn't want to do that. Just replace the whole 1980 style fuel
injection system with a modern kit fuel injection system.
Depending on how technical you are, megasquirt is a very good starting
point. You do it youself, but it has a lot of support for DIY types.
There are many MC engines converted to Megasquirt, so you can get
advice and initial tuning maps from people.
A more upscale unit would be Javad's EFI034; costs a bit more, is a
bit better. There are commercial ones that cost even more than these
two, but they are not as sorted out for the Audi application. I'd
stick with one of these. I have a megasquirt, but not on my '88 5ktq.
I'm thinking of going EFI034 for my Audi.
The modern EFI units avoid the need for much of the FI plumbing from
the original MC donor. Between not needing the wiring and ECU and not
needing to fit the MC airbox and other plumbing, its a huge win to go
with an EFI upgrade as well. I don't think anyone would do a
wiring/ECU swap today.
Take a look at:
BTW the stock MC engine has 162 HP. A used one should cost around
$500. With EFI and perhaps a stiffer wastegate spring, you can easily
get to 250 HP. With a better turbo ($1500 ) and a better Intercooler
(not sure of the $$$, but likely $1000 or so) you can get above 300
You'll be very sorry you asked this question and very sorry you looked
at those sites :-)
