Hey people im new to the mini scene and fort i would start with my first project (going turbo with my 998) so my questions are
1: what is the complete setup i will need to turbo the engine thats all parts evry last fing
2: what head will i need to change to
3: how do i go about lowering the compression ratio

Not to sure else to ask so if anyone can give me a heads up that would be a great help ill get some pics up later of car and engine that i will be converting

Also when i brought the engine im converting i was told it has had unleaded head been put on it along with a new cam not to sute what one but the guy had it on a rolling road an it had 55 bhp at flywheel and 47 bhp at the wheels.

Thanks to all that help in advance an look forward to the coments Marc

Right to start doing a turbo conversion is pretty big, you will want to completly strip down your engine and box otherwise as it's an unknown engine you could put more power through it and find things will break pretty quick, then depending on how much boost you are gunna run you may want stronger pistons and rods, as to what parts you need it would be easier for you to understand what's required to do the conversion over on turbo minis I think someone converted an engine to turbo in a weekend to show it can be done but badly, that will give you an idea on what's needed, and there are multiple threads on here showing how it's done, it's like the old saying "you can give a man a turbo and he will boost for a day or you can teach a man to instal a turbo and he will boost around forever" ( ok that's not the saying but it's more accurate ;) )

But good luck with the build I have always been tempted to turbo an a-series but I find it's just too expensive compared to an engine swap

There's a few inaccuracies here.

1) Standard engines can take a lot of power without modification.
2) Standard rods are strong, I use them on a 180bhp 998 turbo
3) I wonder if you are referring to my weekend conversion? This was more a an exercise to dispel such nay-sayers, thinking that turboing is impossibly difficult and you can't turbo a standard engine, rather than an example of it being done badly. As it happens that conversion was done on a 70,000mile engine that had not been removed from the car since it was fitted by Rover. It ran as a turbo for over 20,000 miles without issue. I then removed the turbo stuff and sold the car, the engine is still in it. Also, it maybe took a weekend to convert; but it took 3-months prepping all the parts to make this possible.

Having said that, I do worry that someone who types 'fort' when they mean 'thought' may end up with an engine bay full of melted engine bits. Also, all the bits needed have been written down hundreds of times, so I'm not going to do it again. Try www.turbo-mini.com for a start.

When I first turbo'd an engine I bought a book on turbo charging so I understood what I was doing, rather than just buying a load of bits. slapping them on and hoping for the best.
