Hmm
Not sure who has told you this Cookie but they are talking utter sh*te :hihi

Its not a simple job to turbo a car that was naturally aspirates (non turbo) from the factory.

Depending on the turbo you may need to lower the compression ratio of the engine with a head gasket, and you will also need to consider the following

Intercooler and pipework
Oil supply and return from the turbo
Inlet manifold
ECU * this is the biggie, you will need to get a custom chip or remap for your ECU that accounts for the turbocharger. THis is a specialist job

Otherwise your car may/may not run, if it does run it will run badly. and it will very likelly grenade the engine in a very short time

Good post above.

I went the s/c route because i like the more linear power delivery, power and torque is instant off the throttle, no turbo to spin up. And its a bit different !

My car makes 4.6psi at 2000rpm and 9.6 at 6500rpm

s/c does sap power from the engine, so for ultimate power turbo is a better route.

look on some of the US forums, they are pumping over 1bar with stock internals

turbo or s/c normally have a bypass, so unless they are under full or partial load they are effectively out.

thats why normal driving you still get good fuel consumption.

why would a turbo have a short lifespan ?? i dont see why you say this
the turbo on the 2.0t's have a span of 100k and most of the cars are over that so i thought if you do 60 mph the turbo would be in, and with that mileage at the end of its life

So what sort of money is ok to pay for getting it mapped once I've put my turbo kit on?
I know what's involved in putting the kit on,manifold,oil feed intercooler pipe etc so what would be after that? And also is it easier cheaper to do this on a say 320 6cylinder?
Thanks for all the info,really helping

good thing to do when you run a turbo'd motor.
when you get home or turn the engine off is to let it idle for at least a minimum 30 secs. this gives the oil a chance to cool down on return from the turbo, yhus prolonging the life.... i should know, i ran one for over 120k in a subaruand its still the original
