first rotary powered deLorean
dunno if this is a repost, but check it out, the first rotary powered deLorean.
ROTARY DELOREAN!!
We've successfully installed a Mazda 3-rotor rotary engine into this car! Rotary people know this engine as the 20B, it is a 1.962 liter engine with sequential twin turbos. This engine was originally made for the Mazda Eunos Cosmo, we picked up a model year 1990. This engine yields about 300HP, and 297ft-lb of torque at 3000RPM. We have not had the time to weigh the car, though the stock Delorean claimed just over a 2700 pound dry weight. We guess that the 2.0 liter rotary and the 2.8L PRV V-6 engine weigh about the same. With this horsepower and low weight, this car really moves!

Hi.
From Wikipedia, the specifications for the STOCK Delorean engine:
Specifications
So, you can see that for the same wight, they have about tripled the horsepower in the car. That is pretty cool...
I drove a Delorean a few times back in the day, and (to be kind), it was not a powerful car by any means.
Also, my Dad had a Volvo 262C of about the same vintage, with the same engine as the Delorean, and it was a slug - could barely accelerate out of it's own way.....
From Wikipedia, the specifications for the STOCK Delorean engine:
Specifications
- Power (DIN): 100 kW (134 hp) at 92 r/s (136 hp at 5,500 rpm) [2]
- Power (SAE): 97 kW (130 hp) at 92 r/s (130 hp at 5,500 rpm)
- Torque (DIN): 215 N·m (159 lb·ft) at 48 r/s
- Torque (SAE): 208 N·m (153 lb·ft) at 48 r/s (153 ft·lbf at 2,750 rpm)
- Compression ratio: 8.8:1
- Bore: 91 mm (3.6 in)
- Stroke: 73 mm (2.9 in)
- Displacement: 2,849 cm³
- Firing order: 1-6-3-5-2-4
- Weight: ~150 kg (331 lb)

The 20B-REW in the Eunos is reported (on several non-Mazda websites*) to weigh 350kg fully-dressed. For comparison, the same websites put a 'racing version' of the 20B at 143kg.
I think what gh8st was quoting was comparing a ~143kg rotary with a ~150kg piston engine.
I have some doubts as to the 350kg number for the 20B (for comparison, a 13G 3-rotor race engine also seems to weigh in at around the 150kg mark).
Hope this helps.

This car was built several years ago. With the original engine, I don't see how it could top 88 mph. This would seem to be supported by the fact that you can't outrun a VW van full of terrorists. The 20B could though.

But why would you want a car that you had to keep under 88 mph, other than the fact of time travel. Speaking of which... i think my flux capacitor is on the fritz again, can someone help?

If I recall correctly, the DeLorean was originally spec'ed out to run on a Wankel from Citroen, but was ditched due to fuel economy reasons.
So this is a return to its true design.

Sorry if this is a noob question. But other than Back To The Future and its RR drive chain...what other significance does a DeLorean play? Why is it so famous?

Well, Wikipedia is your friend....
A couple of salient points (from my memory):
- Former Big 3 auto exec starts own car company.
- Funding from Canadian and Northern Irish governments
- 1979?
- Car made of unpainted stainless steel (later ones were painted / clearcoated)
- Gull-wing doors.
- Relatively low price (about the same as a BMW or Mercedes of the day).
- Company gets into financial trouble.
- Founder (John DeLorean) busted for millions-dollar drugs sting. Rumor that it was to help bail out the car company.
- Company fails... Causes government scandal in N.Ireland.
- 1982?
- 2008 - another company buys inventory and announces that they will re-start production. Haven't heard anything more.

Ross.... I kid you not!
You can get one today starting at $57,500 (according to the website, at least).
