Whoa! I have driven a twin turbo equipped DeLorean since 1987 and I doubt that anyone of this list has put more miles on a twin turbo equipped DeLorean (over 100,000 miles) than I. I have never run less than 7lbs. of boost. I have never blown out the dipstick or any of the other horror stories aluded to in Michael's post. Smoke does not follow me down the highway. Forged pistons are a very desireable upgrade, but not mandatory as long as the boost is kept to a resonable level, say 7 lbs. or less. I like Stephen Wynne, but you must remember that he sells a alternative to turbos. He's right in that you CAN ruin an engine with an improperly installed and improperly driven turbo, but then, you can blow up any engine if you don't treat it right.
