Turbo minis are quality, I always fancied dropping a redtop in one, alas time and money always got in the way. Is it a metro turbo lump? Bore it to 1390 muarahahahh! Miss the mini crowd, use to be a regular on the l2b, mitp, smd etc, good times, really awesome group of people.
Mine is an SPI engine, with most of the bits from a metro turbo engine - but most people just take the complete unit. They're all pretty much the same anyway.
143bhp?! I bet it feels like you've got a rocket up yer bum! How did you manage it? More, cooler air in?
SPI engine, with.. T3 turbo running at something like 14-16psi (standard is 7). Maniflow exhaust. Modified & flowed downpipe and exhaust elbow. Oversized pistons. Chambered head with bigger valves. Ford Cosworth intercooler and a few other tweaks I've forgotten.
You must have whacked some fat jets in the carby I like the airflow setup btw, with all the fresh air coming in from the front, and exiting from the rear, both under the car and up past the lifted bonnet Lemme guess, the induction noise is too good to quieten it and perhaps gain a couple of hp with cold air ducting?
Actually the raised bonnet is a downside - it's a negative air pressure zone. It does, however, mean the stuff fits in the engine bay, where as some of it wouldn't if the bonnet was on properly!
