As you may know I,m having some work done on a new modified cylinder head
and I,m quite excited to see the end result.
Dave - Mr Fixit Enginetuning from here on the Forum is carrying out the work and he and I are throwing around a few new ideas for something special.
Here is one idea we have for a new inlet manifold.
Increasing the plenum length should give more low/mid end power and removing the curves speed up the intake.
Something similar to the third picture as used on the old Lancia Deltas.
Also looking to fit a larger throttle body either from another model or something universal.

Hello Guys,
From having a good search around the net I have found various links, to some modified Barchetta's and Punto HGT's.
Most with power ranging from between 150 to 170bhp and a couple of others between 180 to a 250bhp 10,000 rev screamer. All Naturally aspirated.
Apparently all the power is to be made from the fantastic designed head.
Now, I'm looking to get my B to a more powerful but still drive-able state. so
I have asked for a list of the work being done with the cylinder head and Dave the tuner has told me he will not go overboard with the modifications and just removing imperfections in and around the head casting.
This will allow for some better flow and coupled along with the newly designed inlet and throttle body should get us up the power band but still give us good torque from 3000 to 7000revs.
The bottom end will be dealt with once I have the engine opened up as this is a another head that I purchased although my engine is one of the very first 183a types manufactured in 1995 which from research show to have good quality cast cranks. Early RR tests on the standard engine without mods was producing a healthy 138bhp so slightly up from the 130bhp they are listed with.
Here is a list of the work being carried out to the new cylinder head.
Strip down clean and inspect
Port out inlet ports
Port out ex ports and polish
Finish inlet face
Finish exhaust face
Port match inlet to head
Port match exhaust to head
De shroud valves
De shroud plugs
Re-leave combustion chambers
Polish combustion chambers
3 angle valve seats
Blend valve backs
Clean and polish valve faces
Lap valve seats
Skim head face
Measure combustion chambers and balance
Flow test with postage
Select cams and pulleys
De burr oil and waterways
Atomisation grooves, fitted grooves
Final buff, clean and rebuild
Supply stainless steel nuts/bolts
Weld and polish cam cover
Port and polish throttle body
Make custom inlet manifold, port out and port match
Check variator
Vernier pulleys
Race camshafts
Head gasket with kit
Hydraulic lifters

Uhm! Still not sure as parts and labor seem to be rising, I was hoping to not exceed a 1000 but looks like it may cost more by the time were finished.

I've discovered the cams from the Alfa Romeo 1.8 and 2.0ltr TS are a direct fit into the Barchetta head as long as you replace the exhaust cam timing wheel and keep the Fiat one.
They give a duration and lift to that similar of the mild/ med C&B cams.
A little bit more torque and power so a good mod should you ever need to replace your cams.

Kc3 I was told that the Alfa ts and the barchetta engine were built in the same factory and are quite alike

Yes, I've been told the 1.8 TS Alfa share an identical block and a near setup for the head only with the addition of the 2nd spark plug.
Using the cams from an Alfa 1.8/2.0 which has been done will increase power and torque throughout the rev range.

before and after the 2,0 ts cams, timed with alfa spots....(i dont how you call them)

Hiya, Demy,
Thanks!
Are those graphs from a Barchetta with the Alfa Cams?
Thanks!

Sure KC they are, the thin one is with the original cams and the other (better one) with alfa cams.
The gain was 5.3 hp at the peak but as you can see after the power ends with the original cams it continues with alfa ones until 7000rpm!!!!!

Is this yours! Are those results on a standard set up?
What a surprise I had today.
I was looking for my old RR graphs for comparison, but only I managed to find one from back in 2008 from Red Dot showing 151bhp.
Since then I have had the cam belt changed, new variator/pulleys, redesigned the induction, decatt the exhaust system and lightened the flywheel.
You would expect with these extra mods I would have gained some more power but my my last Dyno a few weeks back was approx 10bhp down from this old figure and a little surprising to say the truth
Although I've done a total of 850 miles since all these new mods were fitted I thought something was not quite wright hence wanting to develop a new engine.
It just wasn't exiting enough but put it down to the cars map that was off.
I was waiting to finish the new induction before having the B remaped tomorrow but today curiosity got the better of me and I went back to check the cam timing.
Would you have it, the timing was off by 2 teeth.
Driving the B home was like driving another car,
Going on the dyno tomorrow morning so lets hope we have gone past the old 151 mark.

OK! Went on the Mustang Dyno this Saturday just for a quick run.
Sine my last Dyno run in UK and the latest modifications.
Decatt 54/55mm straight through mid section exhaust.
4kg titanium billet flywheel, black diamond fast road clutch.
New timing belts, pulleys, water pump.
New CDA induction system.
Managed to run 127whp at the wheels which when calculated is 150.6hp at the engine flywheel and torque peeks at 152Nm so a little down from prior runs but will be going in for a remap next week so hope to push the levels up.

Looks like your "sweet spot" is 59312 rpm where the power and torque curves cross with both almost at maximum. The sweet "window" is around 400 to 500 rpm which is not that far off the Barchetta 3rd/4th/5th gear ratios.
With Barchettas orange/red lining at 6500 and 7000 rpm your curves support a 5000 to 6000 rpm optimum performance window.
Set your shift indicator to 6250 rpm for maximum effect.

Thanks! I never looked at it that way! Things may change again once its remaped this week, trying to keep the power and torque rising..
Although with the up and coming cam and cylinder head upgrade to get another 30 horses

Arh! Yes , sorry, been busy and it slipped my mind. I,ll pm you.
hey KC, that is impressive!!!!! with my ecu(mk2) had the same problem with the bmc!!! didnt work at all.
I hope after the reprogramming you will see the results you expected.
Also i have to add tha the torque curve is not so good before 4000rpm...and that is BMC's fault.......

my co worker tunes engines with specialist software but has no experience at all in regular street cars like fiat
He does those wrock crawlers buggy's verry impressive
what needs to be done to acces the cars ecu (I have first gen 97)
I already have al needed cables and software (fiatecu) to see engine computer.
Can it be tuned with other software?
