Turbo Stilo.

[face]

Thank you Face for your views on Stilo turbo.

But I have several doubts.
Will the coupe 20V headgasket and pistons fit the 2.4 just like that?
Are they of the same dimensions?
Is the diference in displacement betwen the coupe 20V and the Abarth 2.4 due only to a bigger stroke with the same bore?

Thanks again.

Sorry for the delay, i didn't notice this post and now i am going to whip my back for doing that...:icon_lol:

My informatives told me that pistons and headgasket will fit just fine, and the 0.4lt difference between the coupe and abarth engine is exactly due to a bigger stroke...Fiat designers really worked them selfs to death trying to produce horsepower from the bravo brava N/A engine, while following EU emissions regulations...:biggrinsanta:..Which is good for uk abarth owners trying to turbo their stilos...!!:biggrinsanta:

How would this apply to the 1.6 engine though do we need lower compression pistons or just a thicker head gasket could you also give me the cost for doing the turbo conversion on the 1.6 engine [told you I will keep you busy didnt I :biggrinsanta:

A thicker head gasket is an easy (but not proper) way to increase durability up to 0.8bar...It is wise to decrease the compression ratio down to 8:1 to be safe...But by decreasing the compression ratio to that number you get more turbo-lag..

The right way is to replace factory pistons with forged ones (custom made by any well known company ex. acralite). You can "order" them to give you a compression ratio of high 8:1 or low 9:1 to increase trottle response and decrease turbo lag....

the total cost incl. blow off valve, whole exhaust system -not only the downpipe- intake (taken from a lancia 1.6 or bravo 1.6), gauges bla bla bla ,is up to 5000Euros...

If you include forged pistons the price goes up by 1000Euros but the apllied pressure can be increased up to 1.3bar....

In addition it is essential to replace the stock gearbox with a stock punto gt one..2 screws need to be modified..I ve smashed 2 of them stock 1.6 stilo's gearboxes...:biggrinsanta: (4 gear is extremelly weak) :biggrinsanta:....

Thats quite an involve process and didnt realise it was .....did you do all the work on yours yourself ?

I had all this work done by someone who knew what to do...I am just playing smart cause i 've observed all this work ...:weihnacht2:

But Pantelis (1.2 turbo-ed) did all this work by himself..!

Does he live in Thessaloniki as well then 1.2 TURBO !!! jees I bet that goes like a bat out of hell :Snow: how many bhp is it running at ? and was it difficut to do /did it also need another gearbox etc etc etc etc etc :xmas-smiley-004:

Nope in volos like me...It produces from 130 up to 150bhp (depending on the owners mood and finger tickling with that pressure valve mounted on the gear nob)....

The gearbox...He used a different aproach. The "i don't want to smash the gearbox one"..He did not substitute the stock clutch with a reinforced one so the gearbox does not suffer with much strain. Doouch:weihnacht2:

Thanx for your answer face!! :Santa1:

I have some information with regards to turbo charging the abarth 2.4 5 cylinder. First of all I would agree with Face that so long as the pressure is kept to 0.8bar (around 10psi) you should be fine with stock parts, no need to change to coupe ones. The only thing I would fit from the coupe would be the turbo itself & exhaust manifold, I would use a saab9000/ volvo 850 T5 intercooler & as for fuelling I would source an aftermarket fuel pump. With regards to the ECU I would say rather than running a parrallel ECU remap the standard one first & run an apexi boost controller, that should work if only running to 0.8bar. Of course a decompression plate is needed regardless. I haven't done this conversion yet because I'm not allowed to as the person I'm developing parts with won't let me. The main problem with the abarth engine is the crank it's cast rather than a steel item, I have had mine remapped with a proper induction kit & supersprint cat back exhaust & it now pumps out 204.8bhp & 211.1lbs/ft torque & apparently I'm at the limit of the crank already which is hard to believe as I have no sports manifold or free flow cat yet. We are looking into using the 2.4JTD crank which is a steel item & should be more durable. Anyone planning to turbo an abarth will have to consider the cost particularly if planning to run more than 10psi, you would have to replace all the internals then i.e crank, pistons & conrods & possibly cams also.

Very usefull post...especially the crank bit...If you manage to stick the diesel one, it is ideal....You cannot imagine how high the resistance to failure is....!!
