Marin's
Zastava 101 turbo project
Marin
is a very interesting guy - he likes Fiat engines screaming
all way to the redline, doesn't have a problem if he
destroy engine or two and enjoys " junkyard surfing"
through the northern Italy in eternal quest for tuning
parts...yes, with such qualities he deserves it's own
pages - not to mention that he helped me numerous times
with my engine !
I'll
try to explain his plan:
First,
he did few months ago Uno Turbo 1.3 IE engine swap -
OK nothing radical, you'll say. But he wants to install
Megasquirt on this engine and to see how much power
can he "squeeze", then he will remove that
engine and put 1600 SOHC Fiat engine completely prepared
together with T3 turbo,enormuous intercooler, long custom
header, open exhaust,lightened flywheel and Megasquirted
of course, chassis lightened with fiberglass parts if
possible to drop weight, suspension with drag slicks,etc...
What
is he's goal? To make monster Zastava 101 that goes
13 sec 1/4 mile - isn't that just a perfect daily driver
:-)))

|
This
is his Zastava 101 - it's chassis is Fiat 128 based
and they are indeed very similar. Marin did recently
a low cost paint job that turn out pretty well, as you
can see on pic left.
For
now, car must look outside as standard as possible. |
|
This
is his ride before paint job - paint was old and dull. |
|
Sometimes
Marin works so hard on his car that he doesn't even
noticed that turbo flange make a bite on his white T-shirt
, ha,ha,ha :-)))))
Sorry
Marin, I just haved to ! |
|
Uno
Turbo engine is inside - Marin is wrenching seriously
;-) |
|
Oil
cooler placed, well, how should I say ,not exactly invisible...
I
noticed that German tuners like their oil coolers placed
outside on their raced prepared 128's - it seems that
Marin is under strong German influences ! |

One
more shot of Uno turbo engine.

Marin's patented "Original-screwdriver-engine-mount™"

Here is Megasquirt instalation - does this pic remind
you of spagetti ? Me to ;-)
That
instalation will stay messy only untill we finish fine
idle tuning, find use for all connectors on harness
and mount properly all sensors,relays and stuff . |
|
This
is screenshot of my laptop with few Megasquirt configuration
files (*.msq). For now , it seems that car idles best
with Toyota 1.6 16v map slightly modded for 330cc injectors.
Idle
is at 1200-1300 RPM, throttle response is very good
- we must mount soon O2 narrow band sensor and start
some driving and datalogging. |
|
And
this is el cheapo manometer that we'll use to check
fuel pressure on fuel rail at idle. Engine behave strangly
and idle is very rough - I suspect that fuel filter
is completely dirty and/or that pump hasn't enough flow
on higher RPM range. |
|
Here
is our pride & joy freshly mounted and ready to
measure some fuel pressure ;-) |
|
Fiat
Uno 1.4 IE intake manifold is very sexy looking - why
can't I get such nice manifold ;-(((( |
|
This
is Weber TPS potentiometer type from some Tempra or
similar - Megasquirt can't work with old switch type
TPS.
Good
thing is that everything is bolt on - no need to modify
and invent some new brackets - what a relief ! |
|
El
cheapo gauge has plastic cover of incredible quality
so that few gasoline drops on top of it make it almost
unreadable :-()
But
even with some reading difficulties, we measured around
2.9 bar which is in manufacturer recomended range. But
in higher RPM range pressure drops very much and needle
erraticly moves around with 1 bar amplitude - seems
like there is some restriction in fuel supply - bad
fuel pump,dirty filter or something else? We'll see
very soon...
