MOOG: Welcome to another episode of Mighty Car Mods
MARTY: Recently we uploaded 3 massive videos showing you how to turbocharge your car
They went for hours and took weeks to make
MOOG: So in this video we are condensing all the information down to just a couple of minutes
For anybody who's ever wanted to know how to turbocharge their car
And at the end of the video we are going to give ya links for the full length versions so you can get more detailed information
So this is how to turbocharge your car in just a couple of minutes
So the first thing you're gonna need is a non turbo car
This is an MX-5 that we bought for 1500 bucks
You're also gonna need a turbo
We took this one from our Forrester XT
You'll also need a turbo manifold
water and oil lines, dump pipe, exhaust and an ECU to run it all.
Turbos uses exhaust gas to pressurize the intake
so everything before the intake manifold has to come off
as it's gonna be replaced
One of the trickiest bits is the exhaust manifold
You can either buy one premade or fabricate one
But be careful of the really cheap thin wall manifolds as they can crack
and in some cases even send dodgy welds down through your turbo
which causes major damage, and that sucks balls.
We're fabricating this one out of thick-walled mild steel bands.
The turbo is then rotated so the inlet and outlet are then oriented correctly
for our engine and for ease of pipework
which is created out of stainless steel bands.
We're reusing a front-mount intercooler
which has hot air in one side, cold air out the other.
and into our new intake piping.
The spent exhaust gases need to be dumped out of the back of the turbo
and into the exhaust
So we're also fabricating a dump pipe out of stainless steel.
Turbos spin super-fast and need oil to lubricate the bearings
in between the compressor and exhaust housings.
Tap a high-pressure oil feed from your engine block
Or tee off an oil-pressure sensor.
This feeds into the top of the turbo core
and then the low-pressure oil is drained down into the sump
where we've tacked a brass nipple (and nipples are awesome!)
A spinning turbo at supersonic unicorn speeds
creates heat, and water is used to cool a turbo down.
It's tapped from either side of the the water pump
for its feed and return lines, often using the heater hoses works well too.
Extra air in the engine means extra fuel is needed.
The stock injectors may run out of fuel flow,
so bigger injectors are a good idea.
We're going from 220cc to 450cc.
Meaning double the fuel flow,
And a more more modern injector is better for spray pattern and atomization.
An upgraded (or at very least brand new) fuel pump
supplies good fuel pressure and flow,
to meet the needs of the injectors.
An after-market ECU allows you to map for positive pressure inside the engine.
You can go full standalone as we've done,
or use a piggyback ECU which retains some of the factory ECU functions
ECUs need sensors to read air and water temperature
along with manifold pressure and RPM.
Some of the factory sensors are utilized
but we need to install an intake air temperature sensor
to accurately measure the temperature and therefore density
of the air entering the engine after it's been pressurized by the turbo
and cooled by the intercooler.
The ECU is wired in and calibrated so it knows exactly what point the four-stroke cycle
it can then inject fuel and fire the sparkplugs
at precisely the right time as dictated by the mapping.
The car's strapped to a dyno [dynamometer], also known as the rolling road,
which accurately measures power
and allows the tuner to hold the car at certain load points and road speeds.
We've installed an electronic boost control solenoid
that the ECU will control to bring on full boost as quickkly as possible
and then hold that desired boost level according to the engine mapping.
Low load tuning's done first, so the car drives well on the highway and around town
and then power runs are done to map out full-throttle response.
With 146.9 kilowatts achieved on the dyno at the wheels,
a drive on the road confirms the map's complete.
We've managed to double the factory output of our little MX-5
resulting in an awesome driving experience.
MARTY: So that's a summary of how to turbocharge your car.
Now there's other things to consider like clutch, brake, differential upgrades,
and lots of other turbo-supporting mods
but that varies depending on what car you got.
Luckily for you, there's books and Internets full of information
that'll help you get your conversion right.
MOOG: Now the other thing that is really important to consider
is that you've got to see how turbo conversion affects your registration, insurance, engineering
But again, that varies so much depending on your country and region
so you're gonna have to do your own research.
Now the most important thing that you have to do now, Martin,...
