Hi, block, crankshaft, rods are basically the same (blocks before 1990 don't have holes to attach power steering pump), you can eventually mix them more attention with the design of the pistons, that shoud fit the correct heads from 1987 they changed the combustion chamber design (allowing use of lo...

Hi, sharing this here so it can be found with an internet search: Front suspension of alfa 33 S3 had these steps: - from 1989-10: 4 bolts system > coils 321 mm > coils 311 mm on 33 Q.V. (> other specific coils on 33 TD) - from 1991-06-15: 4 bolts system lowered height > lowered 311 mm coils are used...

Hi, hope it can be usefull if I add this: Front suspension parts are slightly different in alfa 33 respect sud, but it seams to me they have a similar dimples rotation scheme: here a photo of parts from one my alfa 33 of 1991 with carbs, considering in my photo the top rings are seen from "below", i...

Hi, I read about this after your post, F3 Novamotor TS engine it is an interesting history I didn't know. I read few technical infos avalaible on the net, probably the same you already discoverd. Engine being high performance ( 200HP with F3 air intake restriction of 24mm, or 240 prepared without it...

Hi, a practical question, it will be easy for you or not (?) get longer conrods that can adapt to alfa 33 crankshaft? Custom made conrods? AHM conrods? Or some from japan cars? About travel vs bore, I will be very interested in reading about you experimenting a super-square boxer, this will remind m...

Hi, in forums I have see some modifications to rebuild alfa 33 thermostat as a serviceable one; one of the most simple mod. I think was one I have see photos posted by Yuri on a Fb group: After opening the alfa 33 thermostat and removing top and inner worn out cartridge, he welded an alu flange/plat...

Hi all, really sad about international situation, reading alfa forum to give me a break and relax if you stil didn't have, considere to have PDF of Alfa Workshop manuals about Sud / Sprint / Alfa 33 (and eventually also 145 manuals boxer engine and gearbox repair section ) PS: I'm quite confident af...

Not sure, but I think the cut is to help gas forming on hot disk surface
under strong braking to exit a bit more and so retard brake fading?

Drilled disk I read they have the same function, help eventually forming
gas to quit surfaces avoiding they can do air cushion between pads and disk

Hi, I don't know if is a reliable option to lower a bit compression ratio, but searching for engine spares I walked in these "lowering CR" heads plates for alfa boxer engines: http://www.alfasud-parts.co.uk/catalog/mechanical-engine-turbo-supercharged-alfa-boxer-engine-compression-plates-p-3050.html...

Hi, thanks for the link! the page has usefull manuals I had not, they permits make correlation between old spare parts codes and new codes Ps.: not sure if I read correctly the image, valve gaps are so different from correct ones? One interesting document for your topic is this one: http://alfasprin...

Hi, for what I can read differences between 95 and 105 (so we exclude all engines with one double-carburetor) where about: - carburetors (36 nominal, with 32mm venturi inner diameter instead of 30mm for 95cv) - not sure about different head air intake port and intake collectors just below carburetor...

Hi, can I ask you if your engine has twin lob cam/tappets systems or the shims cam/tappets systems? I think the more easy way to know (unless some heads swap) what engine is to read the engine code on the block ( as you did, 30520 for ex.); (and sometimes two different codes refesr to the same engin...

..and just in case you already didn't know, usually bolts must be tighted with the car sitting on his wheels or with another system in which the suspensions are compressed at about half ride by the weight of the car This will permit rubber in the bushes to strech less and reduce a lot the risk that ...

At the moment the Oem nissan pistons so economic (kit of four with rings and pins was at 75-100e because used also on some 'humble' nissan pickup) seam a bit less easy to find on-line, I think due to lockdown, I hope they will return more available in few time, but yes, there is a version without th...

Hi Oleino, it's nice to see such a custom project like yours I link here the reference to another project, from Bert308, (1800cc boxer with nissan pistons) if eventually it can be usefull to you: http://www.classicalfaforum.co.uk/forum/viewtopic.php?f=3&t=486&start=30 It seams that slightly ovesized...

Hi, confirming and adding some details about the with/without power steering mod: I think it is from the late 1989-1994 models (S3) that all the engine blocks (hydraulic tappets) have the predisposition holes for the hydraulic steering pump and car can have or not power steering You can find S3 mode...

Hi, later 33 have X-circuit with 4 separated lines, (rear compensator have 2 in and 2 out lines) also if is still use a pump with 3 out, one out of the pump goes to the T connector that serves both one front wheel line and one rear wheel line (opposite side, X-crossed) I have these photos, sorry lef...

Hi, I'm not an expert of AlfaSud, maybe it seams there are at least two quite different front suspensions set for sud, one with very long struts or deeper inferior coil pan, because it sounded to me a bit strange reading about 400mm coil, 338mm seams more normal (but may be for last models) if I con...

Hi, one first thing I will check is if coil lower ball bearing (I mean the ball bearing under the lower coil plate) are shot. Another small upgrade will be modify strut top ending to apcet top mount from alfa 33 last model (90-94) that have another additional small ball bearing also in the top mount.

One other possibility of modification is this: http://alfaimola.free.fr/technique/transmission/commandeboite/index.html About spares: - rubber bush for alfa 33 1988-89 is 60502642 (about 38mm x 19mm OD x 12mm ID) - rubber bush for alfa 33 1990-94 is 60524873 (about 35mm x 19mm OD x 12mm ID) - (gener...

Hi, sharing this about front brakes larger discs upgrade on alfa 33: many treads exist on using opel (vauxall) calibra/astra brake caliper on 33, to put sligtly bigger diameter discs of 22-24mm on 14 rims on alfa 33 on budget. (the only tricky part is have custom brake lines with mixed opel-fiat end...

Hi, this is the brembo cataogue, you can search by car model or by disk dimension (better selecting "2mm tollerance" in red position; Ps: the search module by dimension is quick but it will find most but not all the disks that are present in the catalogue searching by car model): https://www.brembop...

Hi, nice customization, tryng to get maximum from brake disks. I'm not sure but regular rims for golf could be ET 38mm ? using your rims with ET 33 you have a 'virtual spacer' of 5 mm (and maybe also some more millimeters due to larger than regular rims, 6"). This to say that probably you can still ...

Hi, nice to see on picture some precise measures of rims, spacers and 4 pot calipers.
Can you gain some millimeters of space reversing left/right
the image of the caliper or is about the same?

Bob

Hi Bert, always interessant the news from your "personal garage",
very nice idea your set of custom head gaskets.

Thanks, brilliant techniques and explanations.
I will no more dubts about an error in spare codes or spare construction about these bushes..

Hi, I'm seriously curious about, it is a old question also here in Italy between people repairing Sud and 33, someone says he managed to install these chamfering one edge, others suspected that there was an error in spare code (slightly different diameters along the years/models), most choosed to bu...

With the conrods, I think you should weight and mach with other conrods eich side of the conrod (small end and big end, and so also total weight), https://lh5.googleusercontent.com/-j_u6POcdCjQ/VPtAL1BZpiI/AAAAAAAATbA/GrQsTUfCiJQ/w453-h602-no/IMAG1746.jpg http://www.ciaocrossclub.it/root/discoremoto...
