I dont think that engine was ever sold without turbos (the closest I know of is the engine in the merak and Citroën sm, but that's quite a bit different), and there probably isn't much reason to remove the turbos from one.

The early cars were 185hp and low compression, so I can't imagine how little power they have w/out the turbos

The only reason I ask is that Wikipedia says the car was sold in a non-turbo format and it seems like the turbo is the biggest headache with the car. Seemed to me like if you could find an application for the engine without the turbos then you could do engine swap on the chassis and sorta win/win...
The turbos are not the issue.
Would junking the OEM engine management and replacing it with something like megasquirt make it work right?
I think what junked most of them is a combination of tight tolerances on a high compression interference engine with short belt life.

Megasquirt won't fix that.

Nope. A "LS" would.

Okay, so which is it, High or Low compression? Or are we talking about a change from early to late production?
Low compression with turbos. I consider that end product to be high compression, if that makes sense.
stroker, the Biturbo was never sold naturally aspirated (hence the name Biturbo...), can I see your source?
The main issues are the incredibly complicated timing gear and the comparably complicated blow-through carburetor setup. The turbos aren't the issue, the fact that they blow through the carb is. Later fuel injected models are said to be a lot more reliable. But they are all interference, and to call the timing belt a 60k interval is probably on the generous side.
I'd love to put one of the Biturbo motors in a Locost. It'd be a lot easier to work on, too!
I think the actual interval is 30k, which is the same as the alfa milano. The valve gotta adjust the valves every 15k, so might as well do the belt then.
There used to be one around Columbus that was for sale for a long...long time. I think the last price was 500.00.

what's wrong with feathered hair? 70% of the Class of 1980 I was part of got through high school with this hair. (30% had perms)
how many of them still have hair, Pete?

I don't see anywhere on that entire page where it says there was a naturally aspirated Biturbo. If you mean the info box on the right, that is because the 2.0, 2.5, and 2.7 were ALL twin-turbo. Again, hence the name, "Biturbo".
Wikipedia said: ...featuring, as the name implies, a two-litre V6 engine with two turbochargers...

On the right info pane, it says: 2.0L V6, twin turbocharged 2.5L V6, twin turbocharged 2.8L V6, twin turbocharged
Where on the page does it say it was available normally aspirated?
The only thing I can think if is if you are assuming the carb'ed engines are normally aspirated, but they are not.
Of the three engine alternatives in the right pane only the 2.8L is followed by "twin turbocharged". I'd interpreted that as that the first two engines were NOT boosted. The other reference is in the chart under Spyder where it does not list a Turbo for the 1995cc engine but that apparently was never exported from Italy. I guess I misread the right pane as indicating the first two engines (2.0L and 2.5L) were normally aspirated.
I like the looks of these. I don't want one, but I like the styling.
There's a piece of crap Buick Reatta that belongs to the landlord next door that won't go away. Maybe I should try to sell it.

Even the 2.0l in the Spyder was twin turbo. Wiki is wrong.
