I must admit, I browsed Dinans site when I first got the 535i E34, and their prices are a bit mad.
I can only assume there must be shedloads of time involved in rebuilding the S38 engine, hence the price.
When you see the PDF files of people who have rebuilt these engines, it scares me silly just how much time and effort is required.
Dinan have a great reputation amongst E39 owners, so I won`t criticise them too much, after all a $14,000 engine on a car that cost pretty much $70-80,000 when new isn`t that bad.... until 10 years later when the car is worth $14,000. LOL.
UPDATE - From the next thread here !! "
I don't think Dinan is building the s38 stroker any longer nor are they interested in doing any type of custom engine builds. I asked about the stroker a couple of years ago and they didn't want to touch it."
As for their performance gains.... well IMHO totally overstated would be a polite way of saying it.
Look what it took to change a 3.6 to a 3.8, just to get 25 BHP gain, new flywheel, pistons, compression up, per coil ignition, 300cc, errr... other stuff DeWitt is going to jump on me for forgetting. See, loads.
And all along, they could have just reprogrammed the OBC to have a bit lousier MPG. Doh !
To be honest, don`t mod the engine. It is sweet as a nut anyway, so look at wheels and extra options for your viewing pleasure. Choose a nice colour too.
My 2 cents (US not Euro)
