Show us your Maestro/Montego...

[MGTurbo]

Still think the concept of an EFi turbo is great though, pity that it's hard to get a gearbox totally up to the task. Yes, I have been reading the catalogue (year 1995/7). Whilst Motobuild are expensive and not exactly a flawless company it appears that there were very few other specialists for Maestros & Montegos during the 80s and 90s so you can't knock 'em for supplying tuning parts that the average person may never have got hold of.

Easy, just use a turbo box... There are virtually no specialists now because there is a tiny market. However it is my intention to specialise in minor restoration/spraying and mechanical work for this small market. The difference is, i'm not expensive, do a better job than anyone else and wont rip you off... Parts that motobodge do, i can get hold of too. In fact, anyone with a phone can do some investigation and make a huge saving.

Aren't the turbo and EFI boxes identical apart from some metal caged bearings instead of plasic caged ones?

Well, it's easy for me to just drive next door from my house to the local welder. He's doing a pretty good job of the sills. Can't wait to have my car back to start hammeriting the underneath. It'll probably be in the next year or so until I get the car officially on the road though. For the future I'd be interested to know which exhaust systems offer the best performance whilst being the best fit. I don't really want to turn the boost up though at 103,000 miles/15 years old, not that it'd be unreliable - just that I wan't it factory standard (as it has been all its life). There's something special about keeping a car how it left the factory.

Turbo box has an extra taper bearing on one of the shafts. Both types have plastic caged bearings after 87-88 ish.


For the exhaust there isnt alot off the shelf, go to Powerflow who will make you a 2.5 inch system with twin boxes, not too loud and a HUGE improvement in performance for the same boost.

A 2.5 inch exhaust isnt exactly factory standard, you will want to fit a boost gauge as after that sort of mileage your car will be running around 7 psi.

[John S]

So you reckon boost pressure drops over time??? Naturally I'd like 10 psi back if that is the case. I've got a boost gauge, just haven't fitted it.

PS: I did say 99% standard!

No it aint, but a peashooter is a bit gay and you can have a long lasting stainless replacement with a tailpipe that fits through the bumper without cutting, looks good and goes quicker.

Boost will have definatly dropped by a couple of psi if its never been touched. There's no harm taking it to 12psi and having a bigger exhaust. Carb needle wont need to be modified as there's enough fuel at that stage. Would be significantly quicker and would anyone know its running 2psi more at shows????

Hey come on theres nothing wrong with a pea shooter.

John your boost will definately of dropped.

[John S]

Where's the best place to plumb in a boost guage then? (bet no-one has ever asked that before) When I say the car is untouched, I did forget to mention that the carb has been rebuilt and the head replaced not so many miles back but that's about it. Could someone supply a diagram please.

cheers,

Plumb the gauge into the vacuum take off in front of the carb, using a T piece. I used a metal panel replacing the ashtray for mounting my boost gauge.

on the same subject I presume the best place to install my boost gauge on my diesel is to take a T piece off at the injector pump. What should it read at full boost? In the wrong place I know but I can't split a thread off fom this section.

Yeah that would be the easiest place. Should see 13-14psi flat out, taken in 4th gear from about 30 mph onwards. Handy if you have a rev counter too, to make sure the turbo is spooling up as it should.

Gareth

[E_T_V]

I'll be fitting both next week hopefully. I'll let you know how it all goes, as I'm sure there are a few people who'd like a revcounter on their oil burner.

This is my old Mongtego Turbo. Very slightly tuned, 0-100 in about 13s

That Turbo looks lovely and very rare in Azure blue! What became of it?
