Alert me when someone posts in this thread:

To quote Jack Ashcraft (and many others) Speed = $, how fast do you want to go?

A factory 2.0 v4 is English. 1.5 and 1.7 v4 are German. English and German do not have interchangeable parts.

I bought a bored and stroked v4 from Sweden. 1.7 into 2.0. Reground crank, but cracked at all 4 throws. I had a billet duplicate made by Marine in the LA area. I own the settings. Requires the balance shaft to be relieved to clear the rod bolts.

Old SAAB pistons are heavy, replace them with light weight modern forged units. Jack Lawrence did the custom order for me, from JE Pistons. I recommend you also use modern forged rods, but I don't remember the manufacturer I used. they had to be modified slightly.

I used factory dual exhaust port heads, but Jack Lawrence has pointed out that the design has flaws. More to say about that. Cross-ram DCOE 45's.

I replaced 14:1 compression with 12:1 for drive-ability. I also didn't use the most radical camshaft. My meager driving skills will never miss the extra HP, but still dyno'd in the 180 HP range.

I use a race engine builder who specializes in twin-cam Fords. He caught multiple problems that I would have missed. I'm an amateur builder with lots of competing professional and recreational interests besides this. I rely on help from others, projects do get finished, and I have never run out of SAAB tasks.

Current jobs are replacing exhaust header gaskets that blew out, tightening modified speedometer takeoff at the transmission, and replacing banged up hood signed by Erik Carlsson with a newly painted one.

There are many other topics involved in the project you are planning. I have lots of pics from the 96 build.

Now working on a similar 1.7 engine for Sonett with SAAB canted 2 X DCNF to fit under the hood. I don't remember the choke sizes. Jack Lawrence also builds a straight intake manifold for those.
