Educate the uneducated. Turbo'ing an NA car.

For a basic conversion sticking with the stock NA pistons, and not having to crack the engine open this gives you a good idea of what you need

Then if you want to go with more boost low comp pistons and stronger rods would generally be required.

If I'm not mistaken turbochargers, and superchargers are also added to increase engine effeciency?

Turbos yes, as they are driven by exhaust gases but superchargers are driven by the engine itself.
 
-Pedant- Turbos are driven by the engine as well - just via the pressure and heat of the exhaust gas that the engine produces. They are not 'free', and still create a parasitic loss, although in some instances obviously a lot less than a mechanically driven supercharger :)

Both turbochargers and superchargers are used to improve the volumetric efficiency of the engine (the ease with which the engine can move charge into and out of the combustion chamber, with the 'VE' being a ratio - or expressed as a percentage - between the theoretical maximum capacity of the cylinder and the actual volume of charge drawn in).

Both can, as such, be used to improve the overall efficiency of an engine - but it depends wildly on what the engine is, the fuel being used, the workload of the engine and so on :)

You can use turbochargers as a mechanical power recovery device too - instead of an intake turbine, the exhaust turbine spins a shaft which connects to the ancillery drive or crank of the engine to recover the energy that would otherwise be lost in the flow and heat of the exhaust :)

There was a Pug 205 GTi in one of last years Retro Rides (i think) that had a rear mounted turbo. Would make you even more terrified of speed bumps though!
 
Get Maximum Boost by Corky Bell if you want to learn about this in the generic manner you seem to be after rather than disclosing the particular car Phate.

You know what I meant :p
 
all this discussion is nice but what you need to turbo a car purely depends on the car itself.

for example, honda b18 vtec engines will take 400bhp on a completely stock engine, you dont even need to split the engine, just give it fuel, cool air and the right spart and your sorted.

other engines dont need bigger injectors so moderate boost levels,

pick a car and ill tell you what it needs, without that information your list isnt correct and can lead to you spending money you dont have to
 
Make sure to tint all the windows (illegally of course) and put huge chrome alloys on it. Buy a dumpvalve and fit it badly and possibly to the detriment to the well-being of the car - this helps the turbo spool up faster.

Alway, always lower the car on no-name coilovers you bought from ebay. Or from some bloke you met in the pub.

As I understand it, these changes alone give you well in excess of 150bhp (more depending on how far you drop the car).

Yes. Because everybody who modifies their car is a Chav.
 
I have a turbo charger on my car, was quite cheap. Will get a pic in the morning. I think I fitted it right too.
 
I had a 1994 Civic VTi some years ago which I decided to turbo.

I bought a turbo kit from America consisting of

Turbo
Tial waste gate
Intercooling
All piping
Blow off valve
Piggy-back ECU

I added

450cc injectors
450lhp fuel pump

My dad fitted most of it. I was meant to run it round off boost until I could get it mapped, boost was too much fun to resist, my engine lasted one week :D

Next I ordered forged pistons, rods and head studs and had the engine rebuilt, then the car was mapped.

The gearbox lasted a few weeks before it developed a bit of a rattle. This was replaced with an LSD Integra box, I already had a paddle clutch and light weight flywheel.

The car was about 240bhp and was a lot of fun to drive. I do regret spending so much on an old Civic but also glad to have experienced it.

There you go lol
 
if your asking whats needed tbh just get a kit thats available for your engine

the sad fact is without a lot of money spent doing internals its a prety pointles exercise as it will just be unreliable as an everyday car
