147 2.0TS tuning

Hi all, looking for opinions on some planned mods.

I have a CF3 (I think) 2004 147 2.0TS. I've already upgraded the suspension and brakes and am now looking to make some performance mods. I used Alfa CF1/2/3 Engine Identification to identify the engine type, I'm sure there must be a safer way - please let me know!

I've been talking to the Wizard and am hoping to fit one of his manifolds to go with my SS exhaust system. I intend to compliment everything with a sports cat and a remap. I already have GSR induction and am looking to fit a discreet vent in the front mesh to get more air to the intake.

Realistically, how much power gain do you think these combined mods will give me over the stock 150bhp as standard?

Any help greatly appreciated.

Well you need to thoroughly think over the manifold as I had some issues with mine...

Without touching the block I reckon you could probably get up to about 168-170 realistically but every engine is different so it depends...

How about the JTS Camshaft?
It's like a slight sports camshaft and will get you about 10bhp.

I was hoping for 170 or thereabouts. Wizard mentioned some improvements to the manifold to avoid lambda issues with the CF3. Is this where you had problems? Anything else I should be aware of?

Yes the lambda sensors couldn't pick the readings properly, this would need to be revised...

i think with only an inlet mod and an exh manifold mod you wont get past 160, the new manifold only offers some good improvement if you optimise the flow in your cilinder head (flowing etc.)

you can get +-170hp from stage 1 catcams, inlet mod (bmc) and adjusted engine mm.
the manifold itself wont win you much more then 3-4hp (and is very expensive)

i have an supersprint manifold an ss cat replacement and i dont think i won more then 5-7hp tops.
however the sound is amazing!

Hi James,
I'm getting a pair of TS cams re-profiled by piper and with out a map, no exhaust mods on a standard engine +10bhp!

My engine has been rebuilt with a lightened and balanced bottom end,
Full s/s Alfaholics exhaust including custom manifold, they made it 3/8th of an inch larger.
So with the cams should get me to around 185 bhp with a good map, give or take a few

Cheers Andy. Did you mod the head at all?
My only issue is that it all sounds so expensive. I'm wondering whether I should finally just bite the bullet and buy myself a GTA.

I was thinking about looking into increase bhp on my bella but with the cost and hustle and I too have the same idea and get a v6.My dilemma is which one, the 156 GTA, 147GTA or the 3.2 GT.

I rebuilt the head myself and kept it standard, there's alots of debate on port and polishing

The design of the TS head is very good already

Here's a Link

Up to you mate? I wasn't selling my Spider

I've bought a silver GTV I'm gonna super charge/turbo (haven't decided yet) should see 230 bhp to start with

From experience and spending well over 7,000 on parts alone on my 147 2.0. I would recommend not upgrading and buying a GTA, ok I had something great and unique, but then the GTA is

Right, I've decided. No more upgrades to my twinny, the money would be better spent going towards buying a 147GTA.
I can take my FSD's across too!

Go and take a test drive in a 147GTA 1st and see if the car meets your expectations.

OA and guys - unfortunately we don't have GTAs 156s... So it Ia really a case of more serious tunning of the 2.0 TS. I have a cf2 with C&B cams, SS exhaust manifold, 100 CPI cat and 60mm ragazzon exhaust and backbox... Remapped, etc..
Do you think flowing the heads would be a worthwhile mod? There are some mechanics that in addition to flowing the heads modify some angles at the valves, in order to increase the turbulence in the mixture and imcrease power, or so they say...
Never heard in the forum about valve angle mods... Any thoughts ?

Yes, valves can have the seats cut with 3 different angles and the base of the valve reground to change the dynamics of the air passing through

I did all of this to my 2.0. Yes it made the car special, but the cf3 isn't as easy to mod as a cf2 engine.

I flowed the head, increased compression and had 172 cams, with induction and remap I hit 182BHP and 172ft lb torque (the torque was immense, usually its 134ft lb!) To get much more power it would make the car pretty much undriveable at low speeds around town. The high lift cams make the twinspark very lumpy.

I also increased the valves by 1mm on the intake. See below pic....

And the engine itself...

Might as well upgrade to a GTA, I've thought the same seeing the road tax is the same price!

True that or just throw away the engine and fit a coop turbo engine whichever you prefer.

Hey, i am interested in catcams. Does anyone know how are they compared to C&B? See on youtube they are pretty lumpy.

I'm thinking of around 180hp with cams, head p&p and full exhaust including manifold and intake. Tuned by a unichip most likely.

the catcams stage 1 are very decent, very good to live with.
only when its cold outside(beneath 5C degrees) it is a little bit lumpy.
The catcams will give you a bit more torque through the entire rev range, and above 5500 more HP.
But more importantly a wider powerband....it really shifts between 5500 and 7500rpm, There it makes all the diffrence.

i think with these cams and a flowed intake throttlebode and head, bmc cda. you should be pushing 175-180bhp, do know it will cost you, quite alot.

Thanks thamaesta. When you say Catcams stage 1, you mean the Sport ones yeah? I would like more power up the rev range like you said. The 2.0 TS powerband cuts off around 5000rpm i reckon. Only thing, i'm driving a Selespeed so unless i remap and increase my rev limit, i'm stuck at a rev limit of 7000rpm and it changes gear automatically.

I'm sure someone can remap the gearbox ecu as well as the ecu to increase the rev limit.

indeed you need the sport ones, and there will be someone who can adjust your rev limiter

Cool, thanks. You know any Catcam dealer? One that can deliver overseas?
My contact in Singapore is not getting back to me.
