Isnt that how all carb'd turbo minis are set up? Blow through style requires pressure sealing of the carb.... |

Metro turbo used a sealed carb. So do most turboed Minis. 
Float bowl is vented only to the carb plenum. |

Once again.... stand corrected.... The suck through setup seems like the simplest method tho? |

Simple, meaning you can use a normal carb. Not the best... cant exactally cool the air (I think) as it already has the air/fuel mixture. |

The fuel/air mixture is gunna end up gettin chopped to bits once it his that compressor fan. And der, of couse no option for cooling the compressed air... Unless u want to cool compressed air and fuel? |

I've been told fuel/air mix into an intercooler is no good cos you sludge up the 'cooler or something. I can't think that a blow thru would be that efficient due to the heat created. But still doable, but you may aswell get some Metro Turbo bits from UK imported and work from there, unless you want to go custom. Supercharger blowthru however is better than turbo due to the lack of heat generated I think. |

Most aftermarket turbo set-ups, on any car, used to be suck through. The idea was that the carby still worked in a traditional sense in that the air (just more of it) was being drawn through the carby. There are only two real reasons why the preferred option now is blow over suck.
2. On suck through the turbo is under vacuum during idling and low loads. More particularly when the engine is at high speed and the throttle is suddenly closed such as a gear change, this tends to suck oil into the air/fuel mixture from the turbo which increases the chance of knock. Modern turbo's are better than older types but it's still a consideration Obviously there are more complicated issues that we could discuss such as evaporated fuel displacing air (reducing potential power) and blah blah, but suck through has been proven to provide good results. There are plenty of working examples out there, the original Zakspeed turbo mini (QIK850) was a suck through and I'm pretty sure Wayne W's Mk11 is suck through as well. The first rotary's to break into the 9's in Australia were all suck through.... In saying all that I would try to use the turbo metro set-up (or at least the parts) for a conversion knowing that there are limited people who can help out should you have any problems. This is a blow through and will allow you to add an intercooler to the conversion without adding to much cost. Regards Daniel |
