MGB GT
doitongrass - 13/5/07 at 05:31 PM

Does any one know of a good engine to tranplant in to a MGB GT? I dont want to stick with the standard 1.8 or v8.

Thinking of something revy, although the BEC boys recon its too heavy for one of them?!

Any suggestions?

Cheers Dave


StevieB - 13/5/07 at 05:34 PM

As suggested in the BEC section, Honda S2000 engine is probably exactly what you're looking for - loads of revs, very powerful and will easily cope with the weight of the MG.

Plus, since it's honda kit, should be very reliable.


stevec - 13/5/07 at 05:41 PM

Rover Kseries VVC revs high.
Steve,


doitongrass - 13/5/07 at 05:45 PM

Is the rover k series from aRWD car or are they the ones that are simular to the honda vtec engines- b16?


fesycresy - 13/5/07 at 05:47 PM

I've seen a K series done.

Isn't the bell housing big on the S2000 ? How much room do you have in the tunnel / bulkhead ?


britishtrident - 13/5/07 at 05:48 PM

Rover T16 Turbo


rusty nuts - 13/5/07 at 05:50 PM

PPC did an article on an MGB engine conversion using a rover twin cam engine but not the K series. IIRC it was the T series. Might be worth getting hold of?

PS the Honda engine turns the wrong way so you would have to fit the Honda axle.

zetec,you know it makes sence


StevieB - 13/5/07 at 06:01 PM

MG ZT was rear wheel drive and used the K Series, so the running gear from one of those should do the trick.


MikeRJ - 13/5/07 at 06:02 PM

If you like revs, and you want a relatively standard engine the S2000 would be good choice, but they certainly aren't cheap engines/boxes.

Dolomite sprint engine with an uprated cam and twin webers gives an easy 200 HP. Great revving engine.


stevebubs - 13/5/07 at 06:37 PM

The s2000 engine is nice but very very tall. Doubt it would fit in the engine bay.

Rover v8 will
Chevy LS1 may do...


DIY Si - 13/5/07 at 06:45 PM

If it'll fit, and you can afford it, the S2000 engine is precisely what you want. It also spins the correct way, so you may not need to change the rear axle, unless you find the ratios all wrong, as IIRC the S2000 used a 4.4-1 FD.
If not, the K series would be next if you want revs, or the civic engine if there's a RWD kit for it.

3 liter sraight 6 Austin Westminster lump ala MGC.

I have not had to fix one myself, but the engines are prone to knocking out number 3 piston very early, particularly in the states


DIY Si - 13/5/07 at 06:57 PM

Ooh, there's an idea, except using a nice BMW straight 6. I think an M3 engine should prove to be suitably brisk!
And there's space, as tghe BGT was made to accept a straight 6 from the off, hence the bolt in bulkhead/panel thing at the front of the engine bay.

Mg ZT = RWD - Check
MG ZT = K Series - Check.


Unfortunately not at the same time.
The only RWD ZT had a Ford V8, not a K series.


ayoungman - 13/5/07 at 09:30 PM

a mate of mine has put a Zetec into an MG Midget, even got a jag rear axle in it ! he's now fitting a super charger onto it

how abut a montego mg turbo engine
basicly same block so could retain the origanal gearbox and sump
still run carbs so no hassle with efi ect
and i had a mg turbo and for all there faults it was bloody quick upset a few rs boys


marcjagman - 13/5/07 at 09:51 PM

Rover 820/220 engines have same bolt pattern to gearbox.

As zil says. It was the ZT260 with the Mustang motor, and it's HUGE and very heavy

Ideal engine for you is Chevy LS1 motor, similar size to old R V8 but 5.7l and approx 400bhp from crate.

I attempted to fit a 4AG to a B GT, didnt work. The pan ran into the crossmember. But i've got a customer who has fitted a Miata motor and gearbox to both an MGA and an MGB. Fits very nicely.

Only the ZT 260 (V8) was rear wheel drive, ZT are identical mechanically to the R75 except for the suspension.

Lovely engine even the base Rover T16 Mpi engine produced 140bhp, Turbos produced 172 or 190bhp, very strong bottom end.

Only real mechanical fault was oil seapage from the head gasket -- just like the MGB B series.


MikeRJ - 14/5/07 at 12:23 PM

I have some doubts as to how happy the standard B gearbox would be with turbo'd T16 torque being pushed through it...


Catpuss - 14/5/07 at 08:51 PM

Trabant engine. Gives the nice crazy frog ring tone of an MZ BEC.


r1_pete - 15/5/07 at 02:10 PM

I'm in the process of stuffing a 2.0L twin cam sierra motor in an MGB roadster, I've seen one done and looks quite neat, clearence between the oil pump and steering rack look as though it will be tight, wne I get a gearbox I'll have a trial fit and let you know.

david walker - 15/5/07 at 04:13 PM

Montego Turbo? Dolomite Sprint? (oh yeah, 200hp), K Series? Austin Westminster? Sierra DOHC? - you all gone mad


NS Dev - 15/5/07 at 07:28 PM

It would appear so, something funny in the water I think.

Now instead of rebuilding a dolly sprint engine each time you fill up with fuel, why not fit a k series as hundreds already have

1600/1800 K series, caterham sump, caterham bellhousing plus ford type 9 gearbox = job done, all bolt on.

Why make life difficult?

The MGCC Klan will don thier white cloaks light a firey hexagon jump in to T Types and carry you off into the night for doing that. Ford engine (and not even one Ford fans think much of) sullying the enging bay of a pure bred Abingdon built MG.

MGC didn't use a Westminster engine, it was the Austin 3Litre unit --- different engine not a single part shared between the two. A sweet engine in its day but not a sports car engine even in 1968.


r1_pete - 15/5/07 at 09:49 PM

Let the purists howl, if you saw my MG its no sacrifice, if it ever hits the road again it'll be a miracle of the first order - never seen so much rust....
Remember "a kite rises against the wind"
P.S. if anyone wants 5cwt of B series motor give me a shout..


britishtrident - 16/5/07 at 02:04 PM

And the prophet Cecil Kimber servant of the Great Lord Nuffield took his master aside and said that the MGB should live for ever and not be destroyed by the the legacy of evil Baron Stokes of Bald Skull. And Nuffield said "make it so".

Kimber then came down to earth to visit the bold knight Michael Edwardes in dream and said "it would please me and my master greatly if new body shells were made for MGBs and Midgets and these would be sold to barking members of the MGCC Klan who don't have a life. The great white knight was however locked in duel to the death with evil gorgon Red Robbo who was wrecking chaos and plagues of strikes in the once great and fertile Land of Longbridge.

In the morn the white knight Edwardes arose and consulted his only wise servant. Who said "but master we must sell our policies at Abingdon where MGs are made to pay for the war, if not the Huns will invade and Shanghai our people." Then in a flash of inspiration Edwards spoke, "we must take inspiration from the words of our patron and teacher the gentle mistress Thatcher. We are not for turning we must privatise" .

That very day British Motor (BL) Heritage was born and new MG bodyshells were built with special DNA that would never suffer donor rejection.

To use a Zetec would have made a lot more sense, compact lighter, more poweful, a lot more reliable and cheap as cheesey wots its.


Neville Jones - 16/5/07 at 02:27 PM

Just put a 302 Ford in it, mated to its T5 'box and be done. Lots of 'em in the usa.

Cheers,

Couldn't agree more, but, the distributer would end up at the back, pushing the motor too far forward, crank pulley would then foul the steering rack, or push the motor too high, the oil filter location woud screw things up, but I guess remotes are available.
I looked at all sorts of engines, I've done a MGB / Rover V8 in the past, but I recon a reasonably moderrn 2.0L will give comparable performance and twice the mpg, without having any unleaded conversion woes...
Anyway the 2.0L DOHC came at the right price and that clinched it, anyone got an ignition module for a 1990 CARB DOHC Sierra??
Cheers.

Better have been free, and delivered for nowt as well and gold plated Immensly overweight engine, still only 8v and a fortune to tune.

Might as well have stuck a pinto in if you wanted a ford engine, would have allowed you more power for less cash too

If it was me I would have just stuck a small block V8 in for a laugh. Would understeer like hell with all that weight up front, but would certainly be fun in a straignt line.

Either that or done something even sillier like fit an alfa V6

britishtrident - 18/5/07 at 06:43 AM

Zetec dosen't have a distributer


zilspeed - 20/5/07 at 04:06 PM

If you ever find a zetec with a distributor on it, be sure to let me know, because every one I have ever seen has DIS.

(That'll be Distributorless Ignition System).


r1_pete - 20/5/07 at 04:44 PM

OK, the coils, where the ht leads connect, only ever seen pics, never been under the bonet of a Ford..


zilspeed - 21/5/07 at 05:51 PM

That's the coil pack, and like any coil, it can be mounted on any secure mounting point, so it is no impediment to choosing that engine


r1_pete - 21/5/07 at 07:31 PM

Is there a remote oil filter kit available for the zetec? had to use one on the V8 mgb and that was specific to the engine.... Yes you guys convinced me zetec is the way to go, and I've got chance of a cat B 2004 2.0 mondeo.....

I think raceline do a take-off plate...


zilspeed - 3/6/07 at 10:19 AM

Sorry about the slow reply - forgot about this thread.

When I fitted a remote filter to the zetec in the last sylva, it was a universal remote filter kit we used.

Cheers
