Need help

Post

I'm planning to fit a turbocharger in my 1242 cc Fiat Palio.

what are the changes that are required to be made.

Someone suggested that no change should be made. But according to what I know the head gasket, and connecting rod have to be changed.

Can anyone guide with this???

I have fitted turbochargers to non-turbo engines and they need a lot of changes.
I'm not familiar with that car so I can't help you out with specifics but you're definitely going to need to change the fuel system, exhaust, possibly modify the intake system and maybe engine internals depending on whether you want to risk destroying the engine or not!

Then there are other little bits you need to add like oil/water feeds to the turbo and so forth.

Take your car to a qualified auto / tuning mechanic to assess whether it is fit for more power before you do anything.

The same.

Engine internals to change I you want to do a good job: aluminum cast pistons to forged pistons and you´ll need less compresion ratio.

I owed a 1.4L F.Uno and that engine was the same as the 1.6L but with smaller diameter pistons, so, I dont know if it is the same with that Palio, but if it is, you would probably dont need to put strenghtened con rods, bearings and crankshaft because it surplus.

Turbo:
- more air inside engine = more air has to come out = bigger exhausts
- NA comp. ratios goes from 9:1 to 12:1, in a turbo maybe you´ll need 8:1
- check what type of turbine you´ll install:
low speed turbine: low turbo lag, high torque, pressure decreases at high speeds
high speed turbine: high turbo lag, high power output at high RPMs


SUGESTION: if you wanna do those modifications as a hobby to get mechanical skills and experience, go for it!
if you want speed with a reliable car, sell your Palio and with the money you where planning to spend in modifications, buy another car

I was always told to spend my money at the track practicing before I spent it on the car, but here's a pretty wicked modification a friend of mine is attempting.

He runs a Turbo Diesel Citroen CX, this isn't it but its the same model. Image
The plan is to haul a small canister of Methanol in a compartment in the boot, at the press of one of the 'spare' buttons in the roof console the methanol valve will be activated and once the accelerator is depressed 3/4 of the way and held there a jet of methanol and water will be injected, along with the diesel, into the combustion chambers.

Obviously the water is to keep the engine from combusting itself internally, he has done alot of calculations and has convinced me that it will work, and will get the car down the drag-strip faster than just about any other MoTd vehicle on 4 wheels.

I might add that this is the same guy who successfully supercharged a Citroen 2CV and said:
Has to be the wildest car about! It maintains an amazing ability to completely overcome the front tyres and send itself straight on with smoke pouring from the wheel arches!

But it also doubles as convenient transport to and from the shops, and indeed to work, beauty spots, evenings out etc. In fact it's my everyday car. It even starts on frosty mornings!
My aim is to recreate a similar vehicle with an engine in the back so as to avoid that minor understeer issue.

@Tom: I loathe french cars but I absolutely love the citroen CX they're just so much more uncommon than a DS, which so here in holland on almost every corner! Can't get myself to buy one though I have the feeling that they might be all wobbly, if I did though it would make my grandpa very happy he loves french cars 8)

To return to the turbocharging, buy the DIY turbocharging book I think it will be very usefull!
