If you take a look at this topic: http://www.e30zone.co.uk/modules.php?na ... pic&t=2649

There are a couple of options covered there with regard to turbocharging.

My project is a twin turbo setup with throttle bodies and mappable engine amangement, but there are cheaper ways which involve readily available exhaust manifolds etc.

RE: not harming a stock engine, that's no doubt right, but it won't do an engine that's at the end of it's life any favors so depending on the age, milage and condition of yours, it might be worth factoring in for a rebuild too :( [/url]

That Rotrex Supercharger dosnt look too bad, does anyone know if it possible though to turbo.supercharge an M42 18.is engine? Their nippy cars to start with, but with a supercharger i could see it being awesome, anyone know if theres similar kits out there?

You can pressure charge pretty much anything, depending on how much power you want, I'd guess that a supercharger from a new Mini would work quite well and they go for about Ԛ£150 on ebay!

A positive displacement blower would make for quite a nice conversion, lots of low down torque etc.

As with all these things, the engine management is key to getting the most out of it!

P.S. is that a Jem I spy in your avatar SwirlyE30?

It's definately worth calculating how much air your engine will consume before buying the M45.

Have a look at this graph:

As it may be that the M45's too small for the M20 engine.

I worked out some time ago that I needed two of them in order to make about 400bhp on my E36 M3 engine. I does say that they're good up to 3 litre engine capacity, but I've a feeling that they still only support 200ish bhp which is why the Mini people swap them in the works kit.

I take it the M45 is the name of the mini supercharger?

They may be too small for the M20, but how about an M40/M42 motor?

It's not so much the capacity of the engine, but the power you want from it that affects supercharger sizing.

Oh right, so it wouldnt make a difference if it was in a 4pot rather than a 6?


You seem to know a fair bit about this mate, what would you say an ok Supercharger setup would be costing me? And is it worth upgrading my motor to an is or can you get similar results from the M40 1.8?
