Hey, would it be possible to convert an spi engine to carb spec? so it was basically the same as a carbed 1275. Would it need any other mods, ie; does it have a dizzy etc? I really have no idea about modern mini engines!

[Bungle]

yes there are a few topics about this on tmf

the only problem is a carbed injection engine shouldnt pass a MOT

and your reason for this bungle is?

[Bungle]

injection engines and a much more strict emissions test

there was a topic about this the other day with they guy that went to quick fit and they tested his carb engined to mini to the injection test and it wouldnt pass

What you could do is replace the SPi engine for an MG Metro engine. The emissions would then be based on the older engine, and MOTs will be much easier to pass. Also you won't need a CAT.

Also if you do go for this, PM MiniSprocket, He's in dire need of the ECU...... and would definatly grease your palm for it.....

Have a look on IME at my bit on their about the conversion we did.

Why do you want to do this? If your keeping the car standard and your not experiencing problems then be content, the spi system works well when it works properly, iv'e had problems with mine but as a result have learnt a huge amount about "modern" fuel systems as they are often refferred too.

If you are modifying the engine beyond a typical stage1 spec or just want a carb for ease of adjustment then syholl's suggestion of doing a straight swap for an mg metro engine would be a good idea. spi engines still fetch good money on ebay and you could probably pick up an mg engine for half of what the spi will sell for.

what is your reasoning for doing this?

[Bluemini]

Because SPI engines are a heap of shi....

Because SPI engines are a heap of shi....

.......just misunderstood.

Could be due to unfounded rumors spread on forums.....

I think its more to the fact that most mini owners are used to carb's and fuel injection is much different. But as fuel injection systems go, its one of the simpler ones.

[Bluemini]

Minis were designed to use carbs. There isn't enought room in the minis engine bay to fit an injection system practicaly.

The mini would have died back in the 90's if it wasn't for the adaptation of fuel injection for the A-series. Obviously it wasn't designed for it, but it was better that the mini continue production, albeit with a new fuel system than die out there and then. They wern't designed to use turbo chargers, or even to be used as racing cars but they did anyway.

I agree with you the fuel injection system is somewhat cramped, but there are definately worst vehicles to work on. You might say there isn't enough room to seat four people in a mini practically but that doesn't stop people. I've had five in mine + baggage. lol.

nowt wrong with the injection system when it is running right.

nowt wrong with anything thats works right
