Hello people
Can anyone recommend someone capable of making bellhousing adapters/custom flywheels etc? any recommendations perhaps local to Hampshire/Wiltshire ideally but I will travel as far as needed for the right job.
I'm looking to fit an engine to a gearbox and it's not available off the shelf at all, and it's a bit silly so nobody will ever do it again. One off jobbie.
I'm open to suggestions to make it work and have the components out of both vehicles to take measurements etc and then eventually mate together into one filthy dangerous package. I don't have the facilities to make it myself.
I'm hungry to get this done as soon as I can before I spend money on more tat.

Have done this 3 times now. Triumph 6 to Toyota W58 (cut ‘n shut bell housing) Triumph 6 to MX5 (casing chop, weld on adapter flange to take Triumph bell housing) and Zetec SE to MX5 (anothe bell housing cut ‘n shut).
What strange parts are you trying to unite?

Reading with interest I want to try to fit an early mx5 box on to and Mgb engine. I know you can buy kits but not cheap

Our current thoughts are to fit a K-series to a TR7 LT77 and another one to either an Omega or BMW getrag gearbox, probably using adapter plates. Although cutting and welding the bellhousings is a possibility.

good topic, I have this which I really like and will post the build thread of the relevant vehicle soon:  |

i had an adapter plate drawn up/ laser cut by wheng parts in ilkeston to mate a MX5 box to a pinto- i nipped the box down to him so he could measure it.

Could you re-drill/ machine one of the k series to type 9 bell housings to bolt up to the lt77.
If I wanted a modern 4cyl I would just fit a complete mx5 engine and box though.
V engines fit easily and work well in the TR7, you are welcome to come up to essex and sample my V8 at some time.

V engines fit easily and work well in the TR7, you are welcome to come up to essex and sample my V8 at some time. We'd have to get one, and like anything to do with T9s now, they ain't cheap. It would only be of use if the depth was the same, and that's unlikely. The mounting bolt hole arrangements are very different. And we'd have to do something about the hydraulic clutch which adds to the expense. No K-series comes with a RWD gearbox, so we might as well adapt it to the one that's in the car and works. An MGTF will provide all the engine parts, seats, brakes, wheels(if the slotmags don't work) for the TR and a bunch of other stuff for another project, for far less than MX5 bits. The car is intended to be usable everyday, so a four pot is all that's needed for a drivability/reliability/economy/budget upgrade. A Lexus V8 would be the choice for a toy, with Jag or Omega V6s halfway. Realistically a VVC engine offers more power than will be used almost all the time, without any of the compromises. I mentioned a Getrag conversion; that's intended for my Morris 8 project, and I suspect it will be a BMW one for cost and availability reasons. |

Would a flat plate do it? If you can draw one up in CAD they are not too expensive to get laser cut.
I wouldn't do a Rv8 now, 15 yesrs ago it was a cheap easy conversion, now I would probably go the jag V6 option.
Mgf seats are a bit too high for the TR7 (I am 6'4"though) the standard seat has a very shallow base mx5 ones are closer in height.

Laser cutting a CAD design is the plan for a number of projects. The amount of work it saves along with the quality improvement is worth the premium over just buying the material

K-Series in a TR7 actually sounds like a great idea. Although they're 1.8s, the regular VVCs are a good comparison to a Sprint engine. 127hp @ 5200 and 122lb-ft @ 4500 for the Sprint vs 143@7000 and 128@4500 for the K. Like a sprint engine that keeps going for 1000 more rpm.
The 160hp Trophy/later TF engine should be even better.
TTV will happily make custom steel flywheels if you can get the dimensions. Great company to work with.

They're even better when you consider the Sprint 127hp is a lie. Like the 135/160hp that Ford claimed for the 3.0l Essex/2.8i Cologne.
Then there's the cost; a breaker VVC MGF is <£500 and is usable straight away. A used Sprint engine is real money, and will almost certainly need an expensive rebuild. And they're pretty fragile as well as being afflicted with twin carbs and a risible ignition system.

I'm a big fan of 3D scanning. Combine that 'data' from that with one of the legion of 'rent them by the hour' Solidworks or somesuch other software freelancers that are out there and then one of the machine or 'cut on-demand' laser or CNC places here or abroad and far from 'not having the fully equipped garage/workshop to do this' you become perfectly capable of doing this job yourself, very cost-effectively, even if what you are really doing is 'managing' it. I'm not knocking cardboard of mdf templates and spending your happy time chain drilling and wielding a curse word file in hunks of ally for those who want to, but paying someone else to do that these days is like to be expensive with a capital £. Going the digital route means your clutch will thank you for you making the effort to ensure it is actually central your crank too etc...

Marking out the various boltholes and other features measuring from the crank centre isn't difficult. Nor is recreating them in a CAD program like Fusion 360. Do the same with the new bellhousing on another plane spaced the thickness of the plate you intend using and you just need to fill the gaps for a finished part. That's what you have cut by CNC, knowing that it's as good as your measurements. Which you would have checked at least a couple of times, right?

As a few others have suggested, a 2D plate like this one might be possible in your situation, this is one of mine from a 3D scan of engine, gearbox and bellhousing etc. for starter motor dowel positions etc....  |
