Few days ago, I bought a decent '86 Alfa 90, with plan to use it as a parts car for my GTV6 project (http://www.alfisti.hr/forum/viewtopic.php?t=882).

Papers say this 90 have 2.5 V6 engine, but, after seeing it, one friend said he think it's a 2.0 V6 engine. What is the best way to determine which engine I have ?

Another confusing part are 4-hole wheels.

Looking at the injection system, I would say it is a 2.0 V6.

You lucky SOB!

that's the engine to build i screamer from.
Short stroke and NICE intake!

So there was never a 2.5 with this type of injection system ?

Nope, all 2.5's of that era had the GTV6 / 75 / milano intake.
I didn't even know the 90 came out in a 2.0

It was 2.5 only in Australia - we never got the 2.0 v6 in anything.
I'd love to see some close ups of the intake and injection on that one.

I will post a detailed pictures whet it comes home, in a few days.
Any idea where I could find 2.0 V6 specifications, e.g. what parts could I use on my 3.0 GTV6 ? Jetronic type ? And yes, I'm thinking about those cams ...

Try Dutch alfa 90 register A lot of people there, with 90 knowledge.
I think the 2l V6 was rare and controlled by a mm of weber or marelli?

The advantage of that system are 6-throttles, and a I think it uses either a MAP sensor or somekind of hotwire/film sensor.

I wonder if standard (mild) suspension upgrade path would be the same as on 75 ? Poly-bushings + bilsteins all around?
Are all (mechanical, except for engine) parts compatible with 75?

I see 90 is generally considered as a "couch" compared to 75. What causes this, thin torsion bars ?

Since I was thinking about setting-up one 75 (in addition to gtv6) for a daily driver, I don't have a problem beeing a bit different and using a 90 in that role, if all the parts are swapable with 75.

Thanks, Mario

you will find they are nearly exactly the same in regards to suspension. i have actually done the opposite before and used parts from a 90 to fit onto my 75.

On Daniel's request, few close ups on engine:

Thanks Mario, what a great looking setup that's got. Never seen that over here.

The throttle response should be good then. This setup should work really well on a 3.0 V6, although the size of the throttle and plates needs to be increased.

are those runners plastic or r my eyes playing tricks on me? id love to buy a setup like that for a project im working on in the future after i dom my turbo. id use it as a base and expand from there.
