Supercharger or Turbo

sylonien · Post by **sylonien** » Tue Oct 05, 2004 1:53 am

Just wondered if it would be possiblet to add a supercharger or turbo to a "normally aspirated" car engine like the 1.4 Polo in anyway? Or would a engine swap be a much better option?

(Note, just dicussion, not actually doing it!)

putting a factory forced induction engine in is by far the best, cheapest & easiest option.

all the quotes from a company seem to be about 6k for an engine conversion.

i think the cheapest way to go is fitting a turbo - usually costs about 2k - anyone confirm this?

Didn't though it was possible to fit a turbo to normally aspirate car or am I wrong here?

And a what? "Factory Forced Induction Kit"? May I ask what that is all about? Sounds rather fancy? Or just another word for a Induction Kit?

Anything's possible.. you just have to be rather careful that you don't put too much pressure on the N/A engine as it'll almost certainly be weaker than one that's designed to take a turbo.

you usually have to lower the compression when fitting a turbo - so either change the lift or skim the piston heads (i think), or get a new head.

a factory forced induction kit is a turbo or charger direct from the original manufacturer, IIRC

But you can't really get a "factory fitted" turbo for the new Polos, can you?

I just mean use an engine that originally came with a turbo or supercharger on it rather than trying to use one on an engine not designed to take one.

Any type of forced induction (turbo/supercharger) effectively raises the compression ratio, a lot! Any worthwile amount of boost requires significant engine mods, or it will have the life expectancy of a mayfly. As others have pointed out the easiest way to go is a transplant, either that or a fat cheque book & plenty of patience.

actually in the process of developing supercharger setup up for polo 6n/6n2 at the minute can't give u a exact price of setup YET!
its literally just a bolt on system though so no heavy engine mods and as long as you service your car regular you will have no problems with reliability.
roughly at the minute:-
rotrex charger at about 7psi (not confirmed may go up or down yet)
extra row of injectors for manifold and a seperate management system to control including all plumbing and pipe work.

using my own polo for development work

its going on the rolling road after new year to see what the engines putting out as standard
then the system is going on let you know how it goes and any end figures if anyone is interested

theroretically the system should fit any polo

For what engine are you developing it on?

mr toxxin developing the charger on avy eng code 6n2 gti

mr uk polo gti i live eastfield (i know quality place to live)

any chance of this fitting a 6n2 1.0mpi engine? *cough*

as it happens yes might have to drop the boost level slightly but yer should work
