Newbie to this forum, but have mustangs before.

I just purchased a 2000 Saleen S291 coupe with a bad engine.

Do I replace it with same?

Is there an ease swap out to up grade the engine?

Thoughts ? Ideas?

 

The S281 had the stock 4.6L 2-valve engine, with a Roots-type Saleen supercharger, Saleen's cast-aluminum intake manifold, and high-flow (24 pounds per hour) fuel injectors--all managed by custom fuel-delivery calibrations. It also had a Saleen air filter. Presumably you could move all that onto a donor 2-valve block, but you would need that Saleen computer calibration for the fuel delivery, or it will probably just be a mess.

I can't find anything about a Saleen S291. Unless it was a variant with a different supercharger mounted up top.

You could just swap in a normally aspirated 4.6L 3-valve engine from the 2005-11 Mustangs. But then you are looking at a complete CPU swap, and the electrics probably will not play well together. That could become a nightmare fairly quick.

 

Do you know what the failure is or was? I would consider rebuilding before changing to a different engine. Numbers matching is a big deal with some buyers.
