Hi there,
I want to ask you about ways to reach more than 300hp in a brera 3.2 V6 FWD. Do you have any idea about performance parts like camshafts, exhaust headers, intake manifold, injectors, pump etc ...
the goal is to reach 350hp, that would be perfect.
Any suggestions are welcome, please if stating any parts I would prefer a link and specify power gains if possible.
thank you so much :cop:

We're looking to keep the car N/A, but we might think about fitting a supercharger (please if anyone knows from where we can buy a kit that would be an easy fit, provide me with links), unfortunately I am not from the UK.
The car will be for track use only.
the car is not Qtronic, it's a manual.

I think it would be hard to get another 100hp out of a N/A 3.2 without loosing tonnes of driveabilty and with normal available parts. Heads would probably have to be gas flowed and ported etc. And cams would have to be huge. Straight through exhaust and as straight through intake pipework as possible might get you something. That would all need mapping together to make it work.

Yes exactly. What about fuel injectors and pump ? also the intake manifold? has anyone done individual throttle bodies on these engines ? i've seen it on the 2.5 V6 from a 156.

how about an engine switch? not sure if the engine bay of the brera is suitable for this but the 1750TBI engine for instance is lighter and easier to soft/hardtune.
I think that with the amount of money you need to get 350bhp from the 3.2 engine you could also go for a lightweight engine+turbo construction.

Keep in mind that tuners (I can only speak for the netherlands) nowadays can get 300bhp+ out of an Abarth 595 with only a tiny 1.4L engine.

Opt for a supercharger and remap. No experience with the 3.2, but have one in the 2.2 JTS. Mine is from Autodelta (originally installed in 2008) and they used to do this with the 3.2 too. You can try to contact them.

In my case it gave an increase of 60hp (185 tot 245). According to a remap I recently did with a pressure test at least all the extra hp are still there.

Look at web sites in Australia - the engine is developed by Holden, and there a number of off the shelf turbo and supercharger kits that are easy to fit. If you want to take the engine completely apart you can go to 3.8L, again with readily available parts from Oz.

Uprated air filter & uprated exhaust & remap will get you close, especially with a specialist who knows what they're doing, although I have to say I wouldn't want that much power on the front wheel drive version.

You better sort out your oil pressure/flow problems first. And your V.V.T. accuracy; and your positional sensors first. Otherwise the hugely expensive parts you are proposing to spend your cash on, will soon be appearing on e-bay. Alternatively, you could spend a bundle on software up-grades. They can achieve magical results; even overcome mechanical design flaws.

Taking the P155 about software upgrades - of course they can't, but those who spent a bundle on them aren't going to tell you that. Neither will the softies. Then again, you could just buy nice wheels and go-faster stripes and a really tasty exhaust system which sounds at least 40 MPH faster!

Or, you could do this and fit a set of Colombo Bariani cams.:rambo:

Don't take too much notice of Sizewell. His oil pressure claims and mods are still unproven and you will be hard pressed to find any corroboration elsewhere on the 'net.

Just make sure your engine has good oil pressure and there is no sludge in it, nor oil in the intake duct.
(I suspect Sizey's problems were down to a badly worn engine (it had done 100kmiles). Worn bores and rings accounts for the sludge and oil in the intake duct corrugations, and worn bearings for the loss of oil pressure to the top of the engine).

Not sure any engine would make better than manufacturers spec after 100,000 miles plus if any of what you say were true. It might have been as a result of parodying you, going around country lanes on two wheels, in my 159, as opposed to you in your Brera!!!!!!! Would you like to share your rationale for those observations?

No! On the other hand - don't.

It was just an observation on my part. Personally, I think the O.P. should follow your every word, and provide you with the results, to avoid the need for you to do anything other than ponce of everyone else's efforts.:rambo:

You're so predictable!. I expected exactly such as response and we know that you take any criticism personally and respond like a spoilt teen throwing a tantrum. Grow up.

The OP can read your other threads for more of your 'expertise' on the V6 engine, none of which is corroborated by others. For over 300bhp, he will need a supercharger and any idea that you can get the most from mods without also reprogramming the ecu is ridiculous. You do the mechanical stuff first and the ecu work last, assuming you can find someone with the experience & skill.

What you offer is not criticism. Basically you are just a Tw(i)t. You have continued to monitor my every post, not with the view to adding anything useful. Perhaps you could point the O.P. in the direction of reading other threads which would be more informative? Given you continue to "loiter", one can only assume you don't know of any!

As for the last part of your statement, "any idea that you can get the most from mods without also reprogramming the ecu is ridiculous.", just illustrates how little you understand about fundamental engineering issues.

He is talking of over 300 BHP. I did not specify any power increase the oil way modifications would bring. Just, that regardless of what he chooses to do, it would be a worthwhile exercise to address those issues first, assuming he would want increased power, but not at the expense of longevity of his engine.

However, given you are so knowledgeable, perhaps you would like to air your opinion on which of the attached plots are more representative of a engine delivering good economy and output power. More specifically, which would respond more quickly to any throttle input from the driver?

One of these plots is representative of your engine, which is why it is a "Dog" and why you are highly unlikely to go round any bend on two wheels! Of course your's could be considerably worse than either given you have "F----d about with your software, not really knowing what you are doing!:rambo:

This thread went the wrong way, I apologize for that, thank you everyone for your suggestions and I respect everyone's opinion.
The brera project has been dropped in favor of a 156 GTA; I have already posted a thread in the Alfa GTA board.
Thank you very much !
