DATSUN 120Y ENTHUSIASTS SITE
Datsun 120Y modifications are fairly easy these days with lots of
interchangeable parts and after market kits. The Datsun 120y pictured here is
actually my own. This car was originally built and heavily modified back in the
late 1990's by Datspeed. It was originally purchased as a get around car for my
wife. No one ever imagined it would have turned into what it is today. As many
of you here in Sydney may have heard, Datspeed has since folded and moved
on.
The vehicle was originally built by Barry Corner from standard to eventually a
340 Horsepower unit. If anybody knew Datsuns, it was Barry Corner. The
CA18DET was originally in standard form on the bottom end even though it
really was not capable of sustaining this sort of horsepower from a standard
unit.
However, for the odd burst of power here and there, it was more than potent
and handled it quite well. Getting around town alone on 250 HP was more than
enough for get around duties in this Datsun. Well the CA18DET has since
given up the ghost and it has now been rebuilt with the intention of more HP to
come.
The original CA let go of a top piston ring in piston 4 and finally crapped itself.
With the engine out, I finally found the opportunity for the second time in a row
to at last change the colour of the car from what I call Diarrhoea cream, to a
nice bright yellow. This car was never meant to be a show car by any means.
Just presentable and a daily driver with all the punch one would ever need.
These cars have a tendency of being able to achieve just that, when built
correctly. It's almost how Nissan should have built them and also should have
made them available as performance options if one desired so

The car was completely reassembled by A1 Tuning And Performance who
carries out general repairs and high performance work and modifications
ready for transport to the fabricators for a different fuel tank and lines.
The scope for this car as far as 120Y modifications are concerned is to
build something different which is drivable and can be used everyday if
required without the pampering that comes with show cars.

Here are some pics of the damaged piston in cylinder no 4.
This is what happens when you have a partially blocked
injector for about 6 or 7 years and one cylinder constantly
running lean. When it comes to 120Y modifications, This
Datsun is about to cost me a bundle

Consistent detonation will do damage like this.
Detonation here actually ate a hole right through the
piston into the top ring land completely demolishing the
top ring.

By the time this piston was pulled out, there was actually no piston ring left
behind. It actually ate its way through the piston and into the cylinder causing
damage to cylinder chambers bouncing back and forth through the intake
manifold. I could actually sometimes here a metalic tinging sound.

Have to admit CA18DET Rods don't have a bad thickness for standard issue. These rods contended with respectable power and abuse
for a number of years and held out quite well.
Pro Fabrications Minto for Datsun 120Y Modifications ( Not Recommended........If you love your car )
The Ol Datsun 120y coupe was initially entrusted to Pro Fabrications in Minto as I heard good reviews about the guy for further
modifications to the fuel system to run on E85 and air intake tube repairs but after having sat in the workshop for 4 months with no update
call from them what so ever, I figured I'd go check and see what's going on. About the only progress I discovered was a pile of automotive
" SHIT " sitting on top of the bonnet of my car and basically being used as a storage space for other car parts and accessories from other
vehicles. I immediately got rather upset to see my car being treated like absolute crap and you can understand why a customer would
eventually pull out their car from such a fabricator. I don't recall seeing any crap sitting on top of the Lamboghiny though.
I suppose I may be to blame somewhat as well when I said " take your time " but some people perceive this as " you have the car for the
next 12 months without doing nothing on it and you can use it as storage space for other people's shit to sit on it............." Not Really !!
Maybe because it was a Datsun people can just put crap on top of it. Their demeanor and service towards me after me getting upset took
a turn for the worse for the simple reason that I went off my nut. Who can blame me ? I was also stupid enough to leave the car there
because they said they would fix the fuel system. When a Jack Ass don't move while being hit with a stick. Hit with a four by four.
So what did he fix ?
I can at least say towards the last two weeks it made it as far as the hoist and having some aluminium fuel line fitted as well as crappy air
intake repairs. And this is from a guy who is suppose to be good at what he does. Not in this case. Then again, this is the service one
would expect when you see a pile of rubbish sitting on top of your car and go off the handle. Don't expect to be a valued customer after
this in Campbelltown not just in this case but in any business. It's been a valuable lesson to me that when you see your car being treated
like absolute shit, speak your mind and remove it immediately. At least they came good on the bill but, too little too late. Oh and just to
add, I got a message from the guy after I picked the car up asking if there was a pile of helmets in the car. What the !! It turns out there
was. They also belonged to another customer. 12 Helmets being safely stored in my car.....Now that's what I call service. Book your car in
for a custom fuel system, and have your car used as storage space instead. Absolutely bloody brilliant.

EMS
Twelve year old computer just had to go
Ahhh the old Dual Sport EMS. What on earth were they thinking when they built
this dynosaur ? You didn't have to ask any owner of a modified car in traffic if their
GTR or Commodore or whatever had an EMS fitted. All you had to do was look for
the carbon encrusted Ass End and you would know the poor sod was sold a group
firing EMS.
This ECU may have worked well on the track but for
road purposes was a horrible ECU. I didn't know back
then anyway, I just asked for an after market ECU and
this was what I was given. There is nothing more
embarrasing then just squeezing the throttle to just
accelerate a little bit and you look like you are gunning
the damned car as if you are taking off and you are
going no where, even though you are just changing lanes
and behind you is a mess of black smoke endearing all your fellow drivers behind
you. I was so sick of having a dirty black Ass End over yellow paint.

Not only this but, the fuel economy was horrible. Why on earth create an ECU that fires all injectors at the same time instead of the correct
firing order. Did the people at EMS just get lazy ? Was this the same with all after market ECU'S back then ? Well, what ever the reason
was, I was glad to get the opportunity to remove it now that the new CA 18DET had been fitted.
The last thing I needed was a new engine with brand new bores being flooded with raw fuel from a group firing ECU. Perfect concoction for
glazed bores. This was the only downside that made the whole exercise rather expensive in rebuilding this motor was that the motor could
not have a group firing ECU while wearing in. It in turn required another couple of thousand on top of the cost of the motor. All for
sequential firing.

HALTECH SP1000
Out With The Old In With The New
I don't happen to know much about this ECU but it it one of the latest ECU'S to hit
the market for its time and comes highly recommended by fellow car enthusiasts
for its very fine points of tuning, range of map availabilty for road or track and
also allows for basically running of duel fuels such as Pump Fuel or switching
over to E85. How good is that ? It actually even has allowance for traction control.
Traction control in a 120Y !! Imagine that. No thanks. I've always said if you want
traction control, learn to control your right foot. All the traction control you will
ever need. However good this ECU is, Im looking forward to better idling, better
fuel economy for road use and better performance all round from an updated
ECU. I'm not fussed about the track because this car was never really built for
track use and quite frankly will never be raced.

The main aim of this car was to rebuild it the way Nissan or Datsun back then should have built it. You don't build a coupe or as we know it
a " FAST BACK " and stick a shitty little mower power 1200 in it. These little engines may have been great for getting around in the
standard 120y's such as the sedans and what have you but, for a coupe !! I don't think so.
Much in the way that most manufacturers these days have a special design vehicle out of a range of vehicles with all the added benefits to
the standard issue vehicle, this is how Datsun should have built the coupe. If you are going to leave standard running gear from a Datsun
120y into a sports design coupe, then don't build the damn thing to begin with. I didn't exactly plan to build a 120y as my chosen vehicle for
performance modifications. It just happened to be there on blocks in the garage.
It was actually the wife's get around. It just needed a new motor but, when I bought her a new car instead it just sat there for three years
and that was when I decided to do something with it. By then, all the new Turbo design donks were already out and it was a fantastic
opportunity for a power to weight ratio animal that not even the factories offer without having to spend 200,000.00 dollars in the process. It
was really a shame because here in Australia we got all the crap 120Y's while in other countries they camE with completely different styling
and choice of different engines.
It's like Australia when it comes to cars is supposed to get all the shit left overs from car
manufacturers. You look at Mercedes, In Europe they are considered as Holdens, while in
Australia we are slugged with luxury tax, even on the crappy small Mercs. Even in the US, you
can pick an AMG for the same price as a shitty so called performance HSV or FPV here in Aus.
It really is a joke and this is the same with Datsuns. We got all the leftovers from Datsun back
then while in Africa 120y's had a completely different styling. Look at the styling at the 120Y
on the right here. This model coupe had a completely different front end ( much more appealing )
and also came with a different range of engines from the 1200 to the 1600 and up to the two litre.
Now this was certainly not even offered here in Australia. The General idea of my building
of this car is to bring it to how it should have been built to begin with. A small highly powered
and well handling car that accelerates, stops and handles when you want it and so far it is doing everything just as intended
Stay tuned for more to come with the slow development of this project.

Watching this guy wire up this engine was almost
like watching a damned science experiment.
Computers, wires, and gizmos and what have
you. It was actually a relief after three years to
actually hear it kick over with an all mighty blast
of black smoke straight out the exaust and
revving at about 5000 RPM. OOOUUCH !!
With 1000 cc injectors and trying to tone down
the fuel flow was a bit of an exercise.
" Thanks for the big injectors Paul " Was it
necessary ? Who knows, but we'll find out.
Well, after two seperate Sunday's and quite a bit
of time in removing the old EMS and fitting of the
new Haltech, we basically now have a map to get
started with. Considering the way engines have

gone, it was much easier in my day of working as a motor mechanic and just dealing with simple carburrettors instead of having to through
all this. However, when you look at technology and how much power has increased because of it in most common engines, it kind of pays to
steer towards technology of today. Hell, why have 150 horsepower at the wheels when you can have 250. It was unheard of in my days of
growing up that one day small four cylinders would be capable of 400 plus HP. Well there you have it. Please don't ask who the guy is that
wired up the Haltech. He would like to remain anonymous.

DYNO TUNING DAY
Well eventually the day has finally arrived for the Ol Datto to hit the Dyno and maybe breath some life back into the ol Girl but,
unfortunately could not be done with E85 due to reasons that the fuel system was clearly not up to scratch to handle the volatile fuel. Not
only that but coupled together with the cost of the tune it was going to cost a small fortune to get it all running
up together in one hit .
For the time being though, we are just performing
a run in tune on pump fuel just to let the donk wear
in somewhat and get some of the cobwebs out from
the run in. If it's going to be pump fuel for the time
being then so be it.
I had a nasty suspicion that an old VL Turbo pump,
some rubber lines and a Malpasi regulator were not
going to be up to the fuel delivery duties, especially
in volume flow. As is for now I'm going to have to fit all
the goodies bit by bit to trim down the cost.
Starting for the tune, I retired the old fuel pressure
regulator from its duties on recommendation and
fitted in place a 1200 FPR Turbo Smart Fuel pressure regulator to commence duties regulating fuel for the new CA18. This fuel pressure
regulator handles all types of fuel as far as racing fuels are concerned. Not only this but the Malpasi was really out of date with fuel
handling requirements. As it urns out for the run in tune on the dyno capped off at 5000 RPM's with little advance with got results of 177HP
or 130KW at the wheels with about 400NM of torque on 10PSI of boost. 177HP may not be much at the wheels these days but coming out a
1.8 Litre and on only 10 pounds of boost with little of breathing mods, that's not bad considering it is also capped off at 5 grand with no real
timing. Responsiveness is also excellent. The best thing about the CA18 DET rebuild is because we now have new sealing parts, boost has
also tarted 1400RPM earlier. That is a massive improvement. It now starts at about 2400, and is at full flight by 3400. Before the build the
turbo was starting at 4000RPM and was at full flight by 5000RPM. From what I am told, even running E85 I would only gain about an extra
20 or 30 KW. I no longer know if it's actually worth the headache or added expenditure
The power didn't stop there. It continued to climb looking at the Dyno results but we had to cap off at 5000RPM for now. Looking at the
graph here, there is basically boost starting from early on in the RPM'S. It doesn't appear to be your normal turbo type of graph where it
starts flat and then climbs suddenly. It's almost like a V8 Type of curve where power just starts and just continues. Full tune will follow soon
on 20PSI with advance timing.

on 20PSI with advance timing.
Run In Day. RATTS.....No E85 for now.
