The stock ECU is tuneable, so when the engine has been mounted I will just have it mapped. I will keep the alfa heads and all wiring, sensors will be kept stock. Simplest solution I think. Last couple of days I have been thinking... maybe I should have ordered new cams as well... anyway, they can be fitted and tuned later on.

okey.

thought it was pretty hard to tune it, if you look around on different forums, but ive never done it so i dont know
are you planning on using alfa camshafts or GM ones?
Does GM fit right in? cause those are like one third of a price of colombo&barianis. alfas camshaft has a extra lobe for pump i suppose doesnt look like GM camshafts using it

any thoughts?

i think its much easier to install shaft right away.. that was my plan anyway. you need to remove all chaingear wich might be a bit of a problem dont you think?

The gm LY7 cam wont work obviously because of the extra lobe required for the hpfp.

The LLT cam will fit i think but its a rather fruitless exersise as the specs are the exact same as the alfas. The only way to improve cams is to either buy the mace engineering cams. The hyper expensive c&b cams or if you know of a place that specialises in camshafts get your made 210°@.050"

As always, things get delayed. Went to see how things are going and finally the engine has been fitted in the car. Hopefully it will be ready soon.
Alternator fitting had to be custom made for the LY7 block as it had already been told here. Otherwise there hasnt been any trouble with it.
Couldnt replace injector gaskets because I couldnt find them anywhere, even the local Bosch dealer said he cant help me twith these. Hopefully they will not leak.

If anyone is interested I have for sale extra: gearbox, transfer box, rear diff, drive shafts, 1k km driven clutch pressure plate and disc.

Hi

Could you please share some photos of your custom made fitting for the alternator. Im finally removing the engine from the bay (today/tomorrow) and starting to look on new block and upgrading the heads.

Have you done any upgrades fir the engine

How will you upgrade your injection to compensate power?

Thanks

It's alive! It runs! My 3.6 runs!

Sorry, I didn't even see the fitting myself and don't have any photos of it, but I'll have a look if I can take some pictures of it if possible when I get the car on a lift at work. I can probably pick the car up tomorrow evening if there aren't any problems, but hopefully everything is okay. Just wheels need to be fitted and the usual check up that there arent any leaks etc. Can't wait. I'm in doubt that the fuel system needs to be upgraded... injectors and pump wise. I guess we'll see when the car eventually goes to the tuner and on the dyno.

Was really nice to hear it run and rev. Just a tiny bit louder with the rear cats removed - wasn't very quiet with the SuperSprint exhaust to start with...

Hello all, I am Austrian, own a 159 3,2 Q4. I followed your postings with high interest. Seems, in e few month I will be at the point to maintain the timing chains, the idea to purchase a stripped down GM / Holden basement and to prepare an engine calmly upfront, sounds interesting. Because once the engine is out, some other small problems have to revised, too. Looking at the completely diverse spare parts pricing politics, itīs worth to put an eye on. Just, my idea was, to take a GM Holden 3,2 ltr. HFV6 engine as basement, and do the same job as Alfa did -- using Alfa heads and the Alfa sump, having then a replacement engine at interesting price. Does anyone know, which GM Holden engine exactly had the same block Alfa used ? The one from Holden Captiva ? A part number would be very welcome !! So I could check up. Thanks !

The pistons on the Captiva are low compression ratio. The reason I went for te 3.6 build is because it is cheaper. If you can find custom pistons for a reasonale amount of money then ok.
I went for the 3.6 because Camaro pistons and connecting rods cost 50$ per piece and 3.6l engine blocks can easily be found and are cheap.

Just ask from an Alfa dealer how much a new piston costs.

OK, this is an argument. Then better to take a 3,6 LTR engine, take care of right pistons and strip up with Alfa heads and sump and all sensors (just to rebuild the alternators mount). Did you need to remap th ECU ? What is your feeling about the power output of rebuilt engine ? Thanks

I will keep you posted on how much power it will make when its mapped and if there are any problems with mapping.
Im hoping it will make around 230-240kw and 350-360nm as the LLT Camaros do.

On the crank i think you will probably see those numbers but not on the wheels i think. Very curious to see the dyno numbers so please do keep us posted.

My brera is allergic to the dyno. Everytime i want to take her there something new breaks. This time the aircon clutch decided to to seize in the engaged position. Sigh...

i can barely wait

i bought a new car for a couple of weeks ago and had to rearrange in the garage. done with that and a new heater installed so i can operate while its minus degrees outside.. very good. heads are now left for porting at the local workshop. crank is left there too for lightning and balancing with the flywheel.

How will you map it? The dream car would be a 3.2jts mapped for e85 (optimized for power with the option of lean burn on longer journeys). I wonder who is able to to take advantage of the direct injection in these engines.

Got some local guy who seem to be a man with a lot of knowledge about SIDI. He got a rolling road for 4wd cars and promissed me a decent increase in power after engine hardware is upgraded and remapping is done. I will build on llt engine with upgraded heads crank and mace eng. cam shafts. I think, and i hope around 350-370hp will be possible to achive with my setup.

The ammount of work required for this is probably huge, any idea how long it would take for a mechanic at a shop? Or is it rather that if you cannot do it on your own, don't do it? Also, from where did you find the engine?

Not sure im with you on this one...
Its not a very special job. I bought my brera with a streched chain so the car were cheap from the beggining. Work shop will of course charge some money but not very much. Ported head required some time but thats all. Crank and flywheel is pretty straight forward as i learned. Ive bought a LLT engine wich is a camaro or late caddy CTS 3.6l engine. It got 323hp as stock here in sweden. Camshafts, porting and extractor manifold should do a good job among some other small things

Brera 3.6 Q4

I've been driving the car now for the past 2 days and the difference compared to the old 3.2 is huge. So much more torque in the low end and pulls way better all the way to the limiter.
First evening was okay just threw P0430 once - cat efficiency low, because the rear cats were removed. But since yesterday It's been misfiring below 2000rpm. Going to check the coils and plugs. Maybe just needs to be remapped... I think maybe it ran fine in the beginning because the battery was disconnected and the ecu was compensating fuel and it was running rich!?

What concernes in how much work is involved in building a 3.6, then I was charged for 49h of work. Removing and stripping old engine, new engine build and refitting and head work - just cleaning and cutting valve sockets. + extra for block, was honed and crankshaft polished - didn't have the crank lightened. I'm not building a race car I just want it to run smoothly and have the power it should have had in the first place.

Thats great rags. I also got misfire on mine. Do a scan for the misfires then we compare it to mine to see if we got the same issue. I always get misfire on cyl 3 then later 5 will also log and mych later 1 will come along.

I have checked literally everything and just wrote it off as a cam overlap misfire on the mace cams

Did it also misfire before mapping? I remember you saying somewhere you drove the car for a while before mapping it. I get a strong stutter and pop like a fouled sparkplug on a turbo car under boost.

I never knew if it misfire befor the conversion because i bought it with a seized engine. Does yours misfire only when cold? Id it under acceleration or whilst idling?

Seems to do it hot and cold. Only misfires while driving and under load. A gentle accelarations doesn't do anything but like 50% of throttle does it.
