Hey John - the Glenwood GTA motors in 3.2 trim are converted to around 290 crank-horsepower a sea-level. The stocker is rated by the factory at 250 horses... Just FYI.
All the same ! Congratulations - I am excited for you - looks like I will be getting a 3.2 GTA for my street Verde as well.... The conversion is very do-able. My motor would come converted in terms of internal balancing WITH the crank pulley and flywheel - ready for the longitudinal installation.
Your engine right now has an external balance-factor only and it is setup for a transverse installation in the front-wheel drive application of the 147/156 GTAs...
A short-cut way to get around this - but it is not perfect - is to find a flywheel and crank-pulley from a 3.0 12 valve Milano Verde (or from a European 75 Americana), or from an SZ Zagato engine even and to use this on your 24 valve engine in the GTV6.
Once you have the pulley, you would need to press the little timing ring-gear from the 24 valve pulley on to the 12 valve 3.0 pulley (can't be a 2.5 pulley!!!) and either have it tack-welded in place or use machine-screws installed to hold the entire ring-gear "cup" on there (like from the 164 type 60 minus 2 tone-wheel set-up...)
You would also need one of those 3.0 bell-housings OR just use washers/spacers to get the starter-alignment accurate.
Ideally you would just send the entire thing to Dawie at Glenwood - let him convert it to 3.45 or 3.7 or just keep it 3.2 but get the balance-factor accurate and get all of the other little things in line... You will also need any Milano/GTV6 sump - converting it to fit on the GTA is a bear - the oil-pump doesn't clear and some of the holes don't line-up...
There is a deep custom aluminium sump available from Dawie (I have one for you) for 500 dollars USD that will fit over that crank-driven GTA oil-pump. I suggest inspecting the bearings while you are there - BONE STOCK the 3.2s have a propensity towards spinning their main bearings. Once it its right, it is right, but just have a look-see. (I was just at Alfissimo in Jo'Burg and there is literally a sea of GTAs in SA (stockers) with dead cranks and spun bearings - straight from the factory!) The old 12 valvers were so solid at the bottom...
Other than this, you are pretty close. The good news is that dimensionally the block and head externals are identical between the newest generation 3.2 litre 24 valve and the oldest 12 valve 2.5..... The engine would sit RIGHT on the stock mounting points and the stock drive-shaft will bolt right up to the 3.0 flywheel (now on there once you install it...)
I would attempt to get the ECU and stock harness with it, or consider going with a stand-alone engine management system such as the GoTech or other - you may need external drivers for the coils or get a set of VW VR6 coil-packs or Mitsubishi Pajero (or other) 6-pack coil-packs or coils with their own drivers...
More expensive stand-alone ECUs or the new GoTech Pro-X will drive those 6 stock individual Alfa coil-un-plugs without a problem. For now it would be best to run the stock Bosch setup - make sure that all sensors are there such as the knock-sensors... Also, make sure that it comes with a crank-angle sensor (200 bucks USD), the cam-angle sensor (also 200 bucks), the 44mm GTA/164 Q chrome intake runners (400 bucks) and the larger GTA intake plenum!
Fuel rails and injectors (red GTA injectors - can't miss them - 3-400 bucks) and timing belt covers in one piece is also important. Is the timing belt still installed? Do a compression test - depending on how long it sat - this may not tell you anything either...
Good luck with it!
