what engine does the MG Montego Turbo run!?!

all i know is its a 2.0 that produces c.150bhp but is it one of the EFi jobbies? could it be a B-Series? or a K? or maybe a forerunner to the K!?!

also, what about the MG Maestro? does that run the same engine too? i know the Maestro is supposidly faster than a Porsche 944 or something...

any help greatly appreciated!!!

I have a feeling it was the O-Series in both the Montego and the Maestro.

didn't know there was one???

i take it the O-series bridged the gap between the B in the Ital/Marina and the K in the Rover 200/400!?!

any info anyone please?

O series engines went in Maestros, Ambassadors, Montegos, Itals, Rover SD1s, Rover 800s plus a few more I can't remember.
The Turbos only went into the Montego and Maestro.
It was based on a development of the B series block coupled to a SOHC 8v alloy head. (16v versions were the M and later T series engines).

I've had both Montego and Maestro Turbos from new.
The Maestro was the better car (although the Monty wasn't bad either) and easily had the legs of the contemorary BMW the 323i / 325i).
Looked like a pig though, which coupled with a poor reputation for reliability made them about as desirable as a pork pie at a jewish wedding. Only 505 Maestro Turbos were built (with Tickfords input!) and finding a good one these days is tough!
Mine never broke down in 70k miles (plus lots of track days) so maybe it wasn't as bad as legend has it to be.

I am not sure if the Montego uses an O series or a later engine, however assuming the later engine, its called the M16 or T16 - i think the turbo denotes the whether the T is used.... The first O series was developed from the B series but i don't think it ever made it into production before being further altered. This was technically called the O2 series to those *in the know* aparently, but most people just know it as the O series. In reality the only things in common between the B and O series are their outside dimension.

The M16 is basically the 16 valve version i think, with other changes i guess and the Rover 420 i hired (which went like shite of a stike!! well you make that rhyme..?) which had this engine in, produced 136BHP i think.

The Turbo was higher.... The Rover Coupe had 200+ i think....

I have an interesting email from Roger Parker of MGOC who i had scoped out for info as i am investigating engine mods for the BGT. I can post it (providing i can find it!)

Just to be a total anorak, the Montegos had A series (1.3), S series (1.6), O series (2.0), O series turbo, and Perkins diesel and turbo diesel (O series based!)
The M16 series started life as the engine for the 800 range (together with the V6 2.5 Honda unit, which later got swapped for the 2.7 Honda unit, and then swapped again for the 2.5 KV6 Rover unit).
The M16 became the T16 when the 800 range got a facelift in 1991 or such like. The T16 also went in second generation 400 models, the 220 models and even the LR Discovery!
No Maestro or Montego ever officially had an M16 or T16 engine, although a few have been built for rallying and racing.

cheers... now to my next question:

will it fit in a Mini?

and if it does... would it be worth it? or should a 1600 K or something just be bunged in!?!

Probaly - B series have been fitted, and if you can get a Vtec and Vauxhall 16v lump in, it should be possible... (I've even seen a rover V8 mounted transverself on an austin allegra gearbox in the front end)

Probably not worth it - it was IIRC a heavy cast iron lump - better off with a lighter K-series or Vtec

I had a Rover 800 M16 engine in my Montego estate back in the late eighties, it was a very nice car. There was an Austin Rover field service engineer who had some very weird and wonderfull vehicles in his stable, a P6 Rover with a twin plenum SD1 Vitesse engine, a Series III Allegro with a full works Turbo A series, and a Montego estate with a really hot Turbo 'O' with the four speed ZF auto that did 140mph, it was that awfull off white colour with 1.6L badges.

Sounds bloody amazing - saw it at Mini in the Park this summer - still the 8port A-series with twin webers sounded better though...

The engine of choice for Mini turbos is a Metro Turbo engine. I believe it is easiest to convert to a flip-front (weld wings and bonnet together and have the whole lot hine forward.) You also need to mod the bulkhead (as the turbo needs to effectively be in the glovebox!).

Metro, Maestro and Montegos were all blow-thru carb setups.

i know that through choice you'd bung in a Metro lump but i was just curious as to whether the Montego engine was:

a. any good?
b. would fit?*

i don't even own a mini so its not some crazy project i've got going...

*in theory any engine should fit as i've seen everything from a Rover K to a V8 and a Vauxhall BTCC engine...
