Autodelta 3.7 GTA AM engine

Hi folks!

I'm new (-ish) to AO and have just bought my first ever Alfa (a 1985 GTV6 - rear wheel drive, of course!). The car is currently shabby and will, over the coming months, hopefully be transformed into a fast road & track car. I was going to install a standard 147 GTA 3.2 engine but have recently come across Autodelta's 3.7 conversion; does anybody out there have experience with either the 3.7 or any another Autodelta powerplant? Will the unit turn itself in to a very expensive grenade when it hits 7,000rpm for the first time? Or can I expect it last for a few years before it requires a re-build? Any thoughts would be greatly appreciated.

Best wishes from the funny farm,

Paul

Zender 156 V6

Re: Autodelta 3.7 GTA AM engine

Autodelta have one of the best reputations in the Alfa tuning industry and I would say without any doubt that there engines will last for years.

If you search the internet you will find a lot of examples of their 3.7 engine in cars and some cars used by the press too.

Also I think there are some differences between the RWD & FWD V6 blocks so it may not be a straight forward swap to fit a GTA engine to GTV6. Alfaspence is doing a 24v 3.0 engine conversion to his 75 at the moment.

Autodelta are expensive and there are other companies in the UK offering 3.5 & 3.7 conversions based specifically around the RWD engine

156 2.5 V6 24v, Cosmos Blue Metallic, Tan Leather, 17 GTA's, 225/45 Michelin PS2's, Full Zender body kit, GTA Headlights, Eibach springs, Koni FSD's, Eibach Anti-roll bars, Ferrari 360 Brembo calipers, DS2500 pads, Squadra ECU, 45mm Intake Runners, Carbon Intake, Dan & Wizard exhaust

156 2.5 V6 Qsystem, Red + Red Leather, Bilstein dampers, DS2500 pads...soon Brembo calipers, 17" GTV Teles

Before committing try speaking to Adie Hawkins at AHMotorsports as they do a range of upgrades for the track and have a good history in the alfa racing championship.

Re: Autodelta 3.7 GTA AM engine

pjgid, there's also a GTV6 going around with engine rebuilt with stronger parts, and twin-turbo'd

Its been on here before I'm sure, but for those that haven't seen it, look here:

Re: Autodelta 3.7 GTA AM engine

Ha ha if you have the money.... DO IT!
I can't wait 'till mines finished! my 75 was reasonably quick untill it blew number 3, can't wait to feel how rapid it'll be with a 24v mill growling under the bonnet
I did hear something about spacers being required for the crank/flywheel/propshaft on the gtv but i don't know how true this is as my std 75 flywheel bolts directly upto to the 24v's crank. Only difference is the 12v's flywheel bolts are longer and a different thread pitch so new bolts are needed.

Re: Autodelta 3.7 GTA AM engine

Hi again, everyone! Thanks for all the replies - obviously I'm not the only Alfaholic out there!

Originally I'd found a standard 3.2 engine (with ECU & 6-speed transmission) in Auto Italia magazine, however I'm now awaiting a call from Jano at Autodelta about the 3.7 unit. I think around 320 bhp & 250 lbs/ft, when mixed with rear-drive, a slippy diff & relatively narrow tyres, should equal a whole lotta fun....!!

I've already spoken to Adrian at AH Motorsports - he suggested that converting the GTA engine from FWD to RWD would probably be the easiest way of getting the outputs I'm looking for. He also suggested I talk to Alex Jupe Motorsports about other alterations that will be neccessary - this is fortunate as Alex is the poor individual who'll have to put up with my further insane requests for braking, steering, suspension & drivetrain upgrades!! He's also the nice man who is responsible for turning my bank manager in to my new best friend - I really must thank him for that!

Keep posting any tips, thoughts & reassurance - my wife still needs convincing....

Re: Autodelta 3.7 GTA AM engine

My mechanic, rest his soul had managed to fit a 3.2 GTA engine to an Alfetta GTV6 so it is possible. Can't tell you any more details now though because his shop is closing for the summer tomorrow but I could try asking the chief-mechanic when they reopen if he remembers what it took.

Alfa 155, GTV V6

Re: Autodelta 3.7 GTA AM engine

I vaguely recall seeing a post on the gtv6.org website about a 3.2 V6 into a GTV6. they main issue I remember was the sump - they had to make a new one! Otherwise I believe it was not so bad - as far as those conversions go. Had considered the same myself But am going to stick with the GTV v6 I think...

Re: Autodelta 3.7 GTA AM engine

only by emails, maybe i asked silly questions or he is busy, but honestly cant say I was inclined to spend near 4 grand with them!

Maybe a phone call instead would be better

Re: Autodelta 3.7 GTA AM engine

If you look at http://www.alfapower.nu (Swedish site) and ask around, there have been a few 3,0 24V conversions on GTV6's there. The last one is a 3,2 GTA enginge. The site is in swedish, but everyone knows english).

Good luck!

Re: Autodelta 3.7 GTA AM engine

I have an old GTV6 3L (SA version) fitted with a low compression 24V V6 at 3400cc(best size with turbos), I use a BMW Getrag dogleg 5 speed box mounted up front & a BMW M5 rear diff. There are a few of these in South Africa, all done by Glenwood Motors. Also a number of GTV6's running GTA3.2's, only tuning is that they run Glenwoods individual throttle body & GoTech or Motec management, monsters pushing out 400hp+ in NA form.
Check out www.glenwoodmotors.co.za

Head honcho, Dawie De Villiers is a helpfull chap, considered the boss globally as far as the V6 Alfa is concerned. Use me as reference, no probs.

There are around 30 old GTV6's converted to 24V 3-3.7L running around in SA that were built by Glenwood so they are in the know.

Ciao,
Monstro
