The 901 box is strong , we had them in our old VW drag cars and they did not break , 

We also used 240Z half shafts that have Ujoints and also did not die , 

they also come in 4 speeds which is what we used for the shift pattern ,

Any thoughts on mounting the engine at the factory angle versus modding the oil pan and pickup? They both look to be the same amount of work. It sure looked great in Burrito's coupe with the cam gears sitting level but I can't imagine it wouldn't look equally cool at an angle. I obviously lose one of the 4 bellhousing bolts on the 901 in this position so I would have to weld the adapter plate on.

Any issues with oil draining back down into the crank case with the angle?

or oil puddling on the  edge of the valve cover with no place to drain to ?

Considering that is how Suzuki mounted it in countless swift GTIs, I doubt there is a problem.

Trent, I dont have any insight on the angle of your engine's dangle, but is the Porsche transaxle to block bolt pattern the same as an air cooled VW?

I will be using VW rabbit CV shafts. The 90mm inner joint bolts right up the 901 flanges. I am also using the front hubs and bearings from the rabbit in custom hub carriers I am currently machining. 

Space is incredibly tight in a car this small so U-joints are less than ideal.

I have a Fiat 600 and the gearbox is tiny !

I haven't had an aircooled VW engine in my hands in a decade or so.

In reply to RossD :

if you are asking if the 4 bolts ( 2  bottom studs + 2 top thru bolts)  are the same pattern on an aircooled VW  and the Porsche 901 -915-930 gearbox the answer is YES

and you can put a 911 motor up to a bug / bus gearbox.......

What did you guys source the steering rack from on the fiat 600 suspension? Looks like its been shortened? Im running into a similar issue on my 1969 simca 1000(almost the same chassis as the fiat 850). The 68-on simcas have a rack & pinion, but the rack is quite long for the a-arm length I want. Im so excited to see this car on this forum again

That is a Triumph spitfire rack that had to be shortened.

Cool! Yeah that rack really lends itself well to being shortened. Thanks for the hot tip

Scrolling through my watchlist, hoping for an update. I love this car, as well as your ability to solve problems and describe the solutions.

Uh, yes and no? I have come to terms with myself that this project might make Binky seem like an Overhaulin' build as far as time frames go. I fabricate little things here and there, then place them in my toolbox drawer only to proudly show them off to anyone who has the misfortune of asking what's up with the Fiat.

I have recently decided on a total redesign of the rear suspension and subsequently the whole back end of the car which has me itching to tear back into it. 

You see I have recently been having the pleasure of modifying one of my favorite cars of all time

Seeing how Renault did the rear suspension on these R5 Turbos gave me lots of inspiration. 

Acquiring the sexy alloy rear uprights and fittiing some VW hubs into them gets me started.

Anyway, I have 6-7 hours a week for my projects and the last 100 of those have been me moving goalposts around with the mini. That reminds me, I should update that thread. 

Last week I did pick up a disaster of a homemade engine stand based rotisserie to repurpose for the Fiat as soon as the mini is back on the road. 

I'd say "Watch this space" but I don't want to string anyone along.

R5 Turbo rear suspension was parts binned from the Alpine A310 wasn't it?

I'm looking forward to seeing this progress, I'm kind of contemplating a hotrod 850 coupe in the next few years... Abarth OT style but with something different engine wise (Fiat 1600 twin cam maybe, maybe a Honda K, maybe something completely different...)

It seems they did. The inspiration came more from the rear frame rails and shock towers they grafted in. The R5 turbo and the Ferrari F40 I did some work on were both very similar in the rear suspension department but the Renault was done in a retrofit manner that seemed more achievable.

I really wanted to build a R5 Turbo replica a while back, originals being unobtainably priced... Turned out that R5s of any flavour don't exist in Oz anyway. Would be interesting to see some pics of the R5 Turbo setup though. Those uprights are lovely parts.
