[quote=dave33;758187]Been there, done that. I had an 89 S2 car set up for racing and didn't want to start preparing another shell all over again. A Sud would probably be a bit lighter, but I was keen to continue developing the 33. Spares are lots easier to get !

This my logic as well, i already have the car and engine so i might as well use it

i dont have a donor car so fuel setup might have to be custom

The wiring is reasonably straight forward if you work logically through it, although there's plenty of it !
Your current g/box will fit but you will need to grind a little semicircle in the bellhousing to accommodate the crank angle sensor.

what about the clutch, are they the same?

Please budget on new cambelts and pulleys if needed !!

I will do this before fitting the engine to the vehicle, might make things a bit easier me thinks

If you have a 16v with powersteer and aircon, the crank pulley extends too far out in front, and needs modification or replacement with a custom made item or it will foul the radiator.
Also the radiator fan is a challenge - bugger all room to fit it in there, so I ended up finding a non-Alfa one and fitted it to the outside, modifying the grill & bumper slightly (but unnoticeable from the outside.)
You'l need to transfer the exhaust system too.

If it's for competition, forget the power steering IMHO. It is adding weight and dragging power from the motor - why would you do that ?
I also grafted in the bracing pieces from the fire wall to the chassis rail on each side of the engine bay. The S2 33s are prone to cracking on the inner guards and the chassis rails over time. Worth doing, although its a fiddly job as the fire wall isn't dead square on the S2 like the suds & S3 cars are.
That's the bad news, the good news is that the 16v is a good bit quicker than the 8v 1.7 in stock trim. Took 1.5sec off my previous best lap time at Pukekohe race circuit, with the set-uo otherwise the same. It runs sharp and clean, but is a ***** to change the spark plugs on, although I haven't had to yet. Has a rev limiter at around 7K rpm I have found too. :-)
Best of luck, it's a bit of a job, but very do-able.
Happy to assist further if I can.
