The only way to get a 535i to rival M5 engine performance (not even looking at suspension and running gear) is with a turbo. Problem is that no turbo kits are offered for the E34 535i any more.
Swapping an engine is false economy. You want the S38 in the E34 body, just buy the M5 and have it done right (installed at the factory). With the expense of the engine, the labor to put it in, sourcing the DME, wiring harness, transmission, driveshaft, diff, and all the little custom parts, you will have spent as much as the M5 would cost. And you still wouldn't have the M5 suspension, brakes, body add-ons, seats, and the special leather interior. And when you try to sell it... all you have is a bastardized 535i-M5 hybrid that you will be lucky to sell for 10% more than a stock 535i is worth.
Does that help clarify your options?

'94 M5 Touring 3.8 (360hp, 310lb-ft, almost as quick and fast as an E39 M5)
'88 M5 Turbo 3.9 (475 hp, 455lb-ft, much quicker and faster than an E39 M5)
ex-'85 535i Turbo (300hp, quicker than a US E34 M5)
I'm in the market to purchase a 535i. I am wondering if through aftermarket products and an engine swap to the S38, if I could eventually attain the same performance of an M5 without paying such a high price initially.
