So I posted a thread recently regarding low oil pressure and long story short I think Im looking at an engine rebuild in the next however many thousand miles.

What my plan is is to purchase another MPi engine and rebuild this and when the time comes that my current engine comes out I can just swap a few bits and sensors over from the old into the new and away we go, this is just to save the car being off the road for too long and Ill end up with another block for my brother to maybe do the same thing for his MPi if needed.

Ive messaged Minijosh92 and he says hes got a couple of blocks and cranks but no pistons so Id probably need to rebore and source pistons.

Im reasonably sure of my ability to get this done but will need some help, never had an engine apart.

So lets say I get a block and crank from josh, what else do I need and what can I reuse from the old engine? The sensors should all transfer pretty easily what it comes time to swap, anything else worth keeping? I was thinking to just reuse the old head and either refurb that or wait it out and get a professionally modified one when I save some more money

What have people done with an MPi rebuild? I want to do my best to keep this mini as long as I can, so I want it doing right and not need rebuilding with new parts.
what are the limitations with the injection set up with regards to the rebore? Can the ecu handle 1330 or should I just go to 1293?

Any help is appreciated Im just trying to get myself a list going of parts and stuff that needs doing

I would stick with going to the next size up with the rebore.

The injection set up starts to become restrictive at around 85-90 BHP, there are options with aftermarket injection/ecu setups but they aren't cheap.

A nicely modded head will be welcome but you can add around £600 - £700 for that, the injection set up will be ok with this.

You'll need access to various precision measuring equipment

 

About 2.5K in with my build so far, that does include the rebore and crank grind, but the rest is all parts from the list above

A slight alteration to the list above, stick to the standard clutch as the pressure plate/boss alignment is crucial for these engines to work.

Depending on your budget, Id let rob walker do the engine work and guessworks do your gearbox.

Thanks for the reply man, nice list.

That there from mini spares seems like a good enough deal, looks like the most sensible option for someone in my position.

I know the limit of that ECU is around 85 90 bhp so do you think for £774 for a ‘new’ engine as is claimed from minispares then I can save money for a head? Thinking with me having a top limit to my bhp then I can still achieve something I’m happy with just with headwork and breathing mods, maybe a cam?

Guessworks has already built this gearbox for me with the x pin and a 3.44 and I’ve got the MED MPi clutch kit the best one they did.

Nice little discount with your TMF+ membership too.

whilst that may seem like a good option, I have heard reports of these NOS MPI short engines being a little less than perfect.

My advice would be, if you go for this option, is to strip and measure/check everything, in fact this is advisable for all of the build, its best not to just to assemble all the parts together assuming that what you have bought new is going to be right

Sadly it's true. One of the guys on the 500 register was boasting about his new engine a while back, put it together and it destroyed itself. It's what you get for not checking every component on an engine rebuild!

[Austifiniho]

Just re looked at this and it looks like there is no cam, followers or timing chain so that brings the price up of the engine.

Is there much harm to reusing a cam? From what Ive read there is one option for the Mpi cam and its the swiftune one, sw5i I think, so Im thinking to just stay stock, unless you guys know any?

Looks like I might have to just try build an engine up on the side while this one is still ticking over.

Kent also do a cam for the MPI, as to reusing an old one; I guess its fine if its not worn

Kind of strange that Mini Spares wants core blocks in exchange for these brand new (new old stock) short blocks? Why would they require a old block in exchange for a brand new part?

Kent make the Swiftune SW5i under license, which is also a great cam!

Id imagine they re use them in some way, be it rebuilds etc, better to get some use out of the parts rather than throw them away

Of course if you dont send them one back you just forfeit the deposit you paid for the exchange. Like Cian I suspect they have a ready market for the block and crank in the same way they have/had Bill Richards engines on exchange.
