Advice for Mazda 121 1.3i
Albert Leong
Hi, I am from Singapore and is driving a Mazda '92 121 1.3i. I would
like to know what can I do to improve the performance of the car.
Thank you.

Anyway, if I was going to spend money on a 121 I'd put a big jap bodykit
and stereo, mags etc, go for a visual impact.......making one of these
quick would be hard, but I suppose you could do it......I don't know if
you could do an engine swap....the only thing I could think that may go
in would be one of the early jap 323 efi turbos......so good luck with it

Well you can improve it, but you might still be hard pressed to beat
the hot Excel brigade by the end of it!
The usual route probably with EFI engines, decent exhaust (probably
need only 2'' max, probably only even 1.5'') from the start of the cat
back with extractors, cleaned up air intake (try to get rid of
restrictions, cool air duct). I think consensus around here is that
aftermarket air filters probably only filter better rather than
returning significant flow improvements.
That's about the start of it and by far the cheapest things to do with
good gains, everything further starts to get expensive. (Cam/chip
changes, raised redline etc. etc.) With a 121 you wouldn't want to go
overboard with spending big bucks.

If you're feeling creative I believe there is a Jap import motor that will
bolt in, it is called a BJ and is 1.3 DOHC efi. It would be hard to find I
imagine.
Now I wonder if a B6 will fit?

You could bolt in a B1 or B2 but you'd need to paint your car with blue and
white stripes. You would then spend all day chasing Teddy around Singapore.
When up o normal operating temperature, your car would also smell like a
certain sub-tropical fruit.

Won't the 1.6 litre B6 turbo (a la TX3) bolt up to the gearbox?? My Missus
has a 121 1.3 and thats the path I was looking at taking. The handling could
end up being tricky (lethal) but what a SLEEPER!! Nyuk Nyuk imagine that

Don't Chiptorque have a nice new Excel turbo kit out now? I read high
7's?? Do you prefer the 121 over the Excel? 121's are damn ugly
compared to Excels, but then I'm a Swift fan, so what would I know :)

Talking to the guy who developed it at willowbank the other weekend
My mate was racing in his class and ended up against him. The car
was running consistant 15.4's. I was impressed. Stock drivetrain,
all parts are supplied bolt on, literally. Even uses factory
heat shield over the turbo! $4950 for the kit including everything,
intercooler etc. It is so easy to fit, aparrently that they only
charge $500 if you don't want to do it yourself. The kit at the time
was legal just about everywhere but QLD, they were waiting to hear
from qld DOT later in the week. Very well put together kit. Not that
I like excels. Just a good conversion.

I'd like to see how "consistently" long the thing lasts with the
stock drivetrain. Nearly twice the stock output is sure to
cause problems.

$500 sounds small compared to $4950, but it still works out
to be 10 hours of labour! I'd hardly call that an easy fit.
I've never understood people wanting to put a turbo/supercharger
on an Excel. The Excel is crap to begin with, the mod costs
nearly half of the market value of the car, and finally, no mod
to any Excel will help its spiralling depreciation.
$4950 is a little steep anyway, just add another grand and a
similar job on a Falcadore V8 will see low 13's and better.

Yeah, but you can't get a Falcodore that somebody hasn't most likely
treated like shit, for $13990. And you especially can't get one with that
new car smell.

A car is not an investment, especially a falcadore or crapcel.

With all the riceboys around I thought that they would have had a good
market but I 'spose that may increase performance so they would steer
clear of it. ;-)
Performance is relative of course. If you are used to driving a 120Y and
Jump in a VL Turbo you may be impressed. If you are used to cruising in
a Lambogini Diablo VT and jump in a VL turbo you may not be. Most guys
who have modded Excels think they are genuinely quick. Sad really but
they probably are quicker than stock, sometimes ;-) They've just got
to pick who they race more carefully. They don't pick on falcadores
but try and race pedistrians or snails instead or 120Y's

Just to agree with you I know a guy with a 120Y Panel van who runs mid 14's
on an essentially stock drive line. Uprated clutch and welded diff centre
are the only mods. The car is launched at 8000rpm on 8" slicks and lifts
the front wheels. Been doing this for over a year with no probs. BTW
it is a turbo 1400.

Half a car length, in these things is about 1m ;-) or roughly .1 of a second
but a good start would easily make this up.
Paul nelson
I was just wondering if you could give me a quick list of the mods you had to
do to turbo your 120Y. I have an escort that will probably get the same
treatment inthe not to didtant future.
Cheers Nels.

Fuel system:
Carter fuel pump pushing out 97gph but also at 12psi
Malpassi fuel pressure regulator to keep fuel pressure above boost presuure.
If I figure on 4psi above boost this gives me a range of up to 8psi with my current pump.
Feed line to regulator using 3/8" hose.
Return line using standard fuel line. I have just removed the sender unit from the
fuel tank and drilled a hole and soldered a piece of copper pipe so that it is bear the
bottom of the tank.
Also I have a fuelfilter before the pump which is mounted under the boot.
The carby is a weber 32/36 ala 2L ford (escort/cortina). I have removed the choke
plate and bogged up the hole where the choke arm conects to the choke plates.
Currently I run a 135 jet in the primary (as setup for NA 120Y, standard is ~180?)
and a drilled jet in the secondary, about 1.5mm, This is to stop leanout and also
to reduce detonation due to hot intake charge, water injection will go on soon to
counteract this also. It still gives good economy around town when the secondary is
not used (7L/100km) but gives shit economy when the boot is buried(18L/100km) due
to running way to rich, black smoke out the back everywhere. It is my everyday driver
BTW.
The carby is mounted via an adaptor plate and the linkages required a bit of stuffing
around but as standard fitment on the 2L esky you should have no probs.
Turbo:
I am running a T2 off a pulsar ET on a home made manifold, basically the tops off
a standard manifold with box steel welded along the bottom and a flange welded on
to mount the turbo. This turbo is not ideal for a RWD as everything is backward
to what I would have liked. I run a 2 1/4" exhaust with a single muffler, dead quiet.
Oil lines:
Feed is from where the oilpressure sender usually goes with a larger hole and 1/4"
tube running over to the turbo. The return line is about 1" with a pipe welded
straight into the side of the sump. Oil pressure is the same with the turbo connected
or not, I run an oil pressure guage as a precaution.
Water Lines:
Depending on the turbo used you may or maynot need these. I have just T'd into my hoses
to the heater core.
To connect the turbo to the carby I made a new baseplate for the standard air filter
thing with the snorkel on the side (what is it called??) and welded a piece of exhaust
in the back and connected it to the turbo after bogging up all holes and snorkel. I
ran into problems with the lid flexing and loosing boost.
Engine internals:
Stock.
Head:
I have just attacked the combustion chamber with a die grinding bur mounted in a drill to
remove a heap of material to lower the compression. I have also fitted uprated
valve springs. I had a problem with valve bounce over 6500rpm. Now it will rev
off the tacho (8000+rpm) but I find 7500rpm to be the best shift point. I use
as standard head gasket and haven't had problems. I run about 6psi controlled
only by the waste gate, no pop off valve.
Standard drive line, no probs so far. The conversion has cost $600 all up. The
performance has increased a fair bit. It will keep with a stock V6 automatic commodore.
I have only done 1000km so far but have had no problems.
Need any more info etc, let me know, keep us informed with your project. Once you
get all the parts it only takes about a weekend to setup.
Good luck!

Well you can, if you look carefully and long enough. But my point was
not to add a $5-6K supercharger on a $10K near new car, add it to a
$20-30K near new car, say a nicely kept late Fairmont or such. I see
such an expensive modification is better "invested" in a more solid
and opulent car that will end up eating WRX's (well, in a straight
line for beginners!), rather than splurging on a flimsy tinpot
with the end result being only that you can keep up with XR
Falcons and no better.

But pulling low 15's on a stock Excel drivetrain would place the same
loads as being a traffic light bandit. I'm simply saying doing this
over and over will and eventually you will hear that fearful CRACK!

And so the "consistency" of keeping everything from falling apart
will be affected, just like I said!

And yet again you are putting more power into a standard driveline so
you will still have the same "consistency" problems that you would have
with the excel. For a falcon to be eating up WRX's you will be needing a
huge rise in power

Makes owning a sleeper fun. Something I'm sure you can relate to.

No, you keep all your old bits so you can return the Falcodore back to
factory before you sell it. You then put the SC into your new car. That's
the beauty of bolt-on superchargers.

Apart from the immorality involved in doing this to either car, you could also
do the same to the Excel ... and lose less money overall.

Well, then you put the SC in the non-Falcodore assuming it's not a turbo/SC
or something like a 300ZX where you can't fit anything bigger than a tennis
ball. Surely, you'd think about the applicability of the SC in your next car
if you were going to remove it.
