@porsche928fan Yes, it's been detuned for street use. There's a knob to increase boost and horsepower. it's currently at 550 hp, and you can increase it from there. I will share more information tomorrow once Robin replies to this question.
is this engine streetable or mainly for race track?

@porsche928fan Yes, I removed the engine from a 1987 930 Turbo with the factory whale tail.
would this fit stock 930 turbo bodywork with whale tail?
935's are 'flat' fan motors

As an engine builder Robin Reddy is incredible. I own a 934 replica that he built. The motor was a 1979 3.3L bored to 3.6 and paired to Kokeln turbo producing 500 HP. A street legal monster.
The suspension wasn’t set up very well - it was lowered too much. Bob Farmer had to adjust it. Currently one of the best Porsches I have diriven/own.
@group911 Engine was built by Neal Harvey and rebuilt by Robin Reddy of artesian motor
@muhamad7323 I'm confused. You say the engine was built by Robin Reddy but @Helix10 say sit was built by Neil Harvey. Can you clarify?

@Daryle I purchased the car at 80% completion. The engine rebuild was complete, and the previous owner was working on converting it to a street version. They had removed the gas tank and installed a factory gas tank, and they were Planing on fabricating an oil tank to fit in the back. When I purchased the car—a 1987 Porsche 911 Turbo Cabriolet—I thought the engine was overkill for this build. So, I took the engine and transmission out and decided to bring it back to the stock engine and transmission. As a result, I never started the engine, and it hasn't been started since the rebuild.

Would you happen to have a video of the engine running on a test stand or dyno?
GLWA - extremely nice engine and transmission built by one of the very best (Neil Harvey).
