One of our friends has a Supercharged 1.7 16v IE race car, although it isnt running currently as it dropped a valve in september last year. it sure can be done! the main problem for him is getting the power down to the ground, the best setup for him is 16x10 racing slicks.

Im only running here from personal opinion not solid fact, but i dont think the 16V shell is a very good start for any serious project. It looks great, but its not that stiff. I know when ours is jacked up its hard to open the doors. Granted mine has had a hard life, but friends cars exhibit similar symptons - one has shown me where a small amount of paint has cracked off from body flex on the track.

If you want to build a hot boxer I personally think a 2 door sud or sprint would be the ideal base. Espicially if its all apart a few bracing bars and/or cage would make for a strong, light shell which would be great for a high powered boxer engine.

I know its not Alfa but i cant beleive the torsional rigidity of my X19 Fiat. At the moment its just a shell undergoing resotration, and the other day i went to change the jackstands. I noticed that it was only sitting on 2 of the 4 jackstands (FR and RL) yet it was rocking between the two of them. It doesnt droop at all, and it doesnt even have a roof!

on another supercharged note a friend of mine at uni was involved in the buildup of a supercharged boxer for an open race car. I havnt seen the car driving, but have seen a video of the engine running and it looks amazing. Its running massive boost, somewhere nearing 20psi think and last time they tested it, it used 22 litres per hour of fuel at idle! Next time I see him I'll get him to sign up as a member here and maybe he can give some insight into this nuts boxer?

I had a similar experience with my Sud and jackstands, it sat stripped for several months and I noticed it was only using three of them and it never changed over those months....and yes the 33's do flex a bit and so too do Suds when jacked up, all that weight right up in the nose.
As for the Supercharged boxer guy - Jono, he was a regular Poster here on the BB, his name was KABOOM, haven't heard of him for a while now....be good to hear what hes up to with his boxer projects.

That photo I found in internet, never met the guy really.

I have read one posting here to advised about to change for SUBARU engine.

Does anyone ever have the information to do that into 146?

As 146 is front wheel drive, yet SUBARU is 4x4, How to lock the rear drive? What will be the mounting will be.

Here in Malaysia, a lot of JAP car engine conversion, BMW with Nissan Skyline engine, or TOYOTA SUPRA and so on.

Of course, It does killed the feeling of driving the true BMW or else.

To maintain the BOXER 1.7 is a bit troublesome in MALAYSIA, the true expert to do the maintenance and upgrading here is very busy where it takes you several month to swap the engine due to the demand.

Where other mechanics is just a "clown" when it comes to the itallian engine.

So the option left is only to swap the engine into JAP engine.

The question is, is there anybody in this world have changed the boxer into SR20 or SUBARU? Does anoyne have the info, photo or whatsoever? please notified me.

Hi Tiang,

That's some impressive work on your car there, that turbo manifold is a work of art! How much did it cost you?

I've heard of people putting the subaru motor in the boxer alfa's, so it can be done. Don't have any information more specific than that, unfortunately.

Hi Spooty,

As i Just mentioned, I get the photo through one link, Cardomain. http://www.cardomain.com/ride/617055/10

I still try to locate the owner just wanted to see the real thing. I know that only 2 guys did this turbo on the boxer.

You may browse to the link to read more.

Anyway, the subaru in alfa is interesting. Reliablity of 5 bearings and so on. But the true feelings of Alfa will be not there.

I know it could be done, but still want to have some info about it. I ever read and watched the video of VW Bug with ALFA engine, VW Bug with rotary. VW bug with Toyota engine. The rotation of rear engine and front engine is reverse if i am not mistaken, yet that guy could manage to put ALFA boxer front engine into VW rear engine bay.

Really hopes that anyone with the information about subaru in ALFA or any JAP engine in ALFA could share with us.

Rotation can be reversed by changing the orientation of the differential. Not always possible in most gearboxes, but I'm pretty sure this could be done on the 'sud/33 transaxle, however a new bottom plate would need to be manufactured.

"Reliability of 5 bearings" is rubbish if the engine is maintained with regular oil changes with a quality oil. Replacing an Alfa boxer engine with a WRX motor is a waste of money - you might as well buy a WRX. The 33's boxer is what gives the car its unique character to begin with. A 33 16v only needs a moderate increase in power from standard, spend the rest on handling, wheels, brakes etc and you will out perform a lot of modern cars - just ask Flyboxer!

**** straight boy, there is no point putting something in that its not designed for. The alfas dont need sheit loads of power cause they handle bulk good, and if you spend as much attention to the handling and braking as i have you won't really be beaten. Its not all about power:D

A 16v turbo would be good. A non-cat 16v 33 puts out 138 bhp in standard format. It wouldn't take much boost to turn what is a fast car (0-60 in just over 8 secs), in to a very fast car.

Using moderate boost could be practicable at a reasonable cost. This is a rough guess here but I would have thought you could get away with a very well rebuilt stock 16v engine (new valve guides, conrod bolts, flywheel bolts etc), having machined the pistons slightly to lower the compression and be good for 10-12 psi.

10-12 psi would give you between 180-200 bhp with a good level of torque. The torque and accelaration from an engine like this in a 33 would feel like you've just dumped a 24 valve V6 from a 164 under the bonnet/hood :D (we say mum you guys say mom).

The 16v 33 only weighs 1000kg. Just imagine this setup in a series 1 sud which weighs 810kg.
