I think it's more likely to go the other way...that is forged rods being found in later cars as stocks were used up, remember the forged rods were also used in the early NA cars, costs and perhaps experience due to use, stopped their use as engines didn't seem to blow up. Also worth bearing in mind that the early turbo engines 85/86 had thicker sleeves for their bores, not by much but it all counts, they truly were over engineered and thus able to take serious modifications above that of the later cars as has been shown in the past, Fen's car being an example of what can go wrong with cast rods. Engines failing though are not just about parts being stronger in the earlier engines, they too can fail. It's also about ensuring the engine is in good order before improving performance, how many check the piston pin bearings? there is a design flaw on No.2 which gets less oil flow due to it's position in relation to other internals parts ( sorry can't remember exactly what the issue is off the top of my head, iirc something about oil circulation perhaps). I was shocked when I checked mine during it's rebuild although not too surprised considering how much extra power it had been producing for many years, I have no doubt that if I rebuilt it without changing the small ends it wouldn't last long. As T3rra states a well tuned MAF kit will help greatly with spool up as much as with extra power. the original AFM really is worlds away from a good MAF/MAP kit. The 944T is a truly wonderful machine in any form, early, late, standard or modified they are in a class of their own...enjoy...
