I have chosen to rebuild a couple of V4 engines. I already dismantled three spare engines I have, so I can get the best bits and pieces from them.
One motor will be close to original specs for the future 95 project. I will use mainly used parts for this to keep cost down. The engine doesn't really need to be like new, as it most likely will never be driven more than a couple of hundred kilometers per year.
A used pair of heads for the 95, in very good condition (propably about 100 000 km on them at most). I also have a rebuild pair that I might use, they are as good as new.
The other one will be a tuned up unit for the B105.
So far I have been gathering parts for it. I have the Ford 1.7 litre crankshaft and a 7.6 cam. I will also have a lightened flywheel machined (the intermediate version, with just the outer rim machined off).
The biggest job will be the heads. The intake and exhaust ports have already been opened up to the specs of The Manual. I will need to have bigger valves fitted. The exhaust will be a self made freeflow system.
Also the intake manifold needs to be opened up a bit. Below you can see the original one that will be machined later. When I took the photo it was glass bead blasted only halfway. It looks really nice completely done.
I'm still thinking about what carburetor to use, but most likely it will be the original Solex with drilled out jets. If it works I will have saved quite a bit of money. If not, I'll get a Weber. (Ofcourse I'm dreaming that the crossover intake will somehow magically appear on my doorstep...)
The engine block will be machined and the bore opened up to 92 mm.
The original distributor will be replaced with a breakerless ignition system and the cooling fan will be replaced by an electric unit. In the picture the fan bearing has already been removed from the timing gears cover, now I'll have to blug it somehow.
Well, this should be a nice winter project (and expensive). Hopefully the engines will be done before the summer.

Ok. The Saab 95 engine is now partly put together, here's the cover painted with new seals and new fan bearing:
The heads were carefully sandblasted and then put together again.
