At the end of the year it's going to Paul at minicraft in Kent for a new front end and a respray. I visited 3 different body shops and settled with him as he only works on minis, does 1 in 1 out and seemed reasonably priced. Anyone have any feedback about paul's work?
While it's the engine is out I am looking at either a rebore to sports tourer spec at swiftune which is down the road or at specialist components. Swiftune we all know are pretty awesome but not cheap. SC I can't really find much feedback on. I am considering a 7 port if the funds can stretch. I have heard some casts have porosity issues. Their billet head is really pricey though. I am not sure whether to stick to what I know or go for it. Anyone guide me please
Cheers

I would be miffed though if I got the swif tune and had 20hp and torques more than I have now and found it still to be a bit on the sluggish side

Choose the gear ratios carefully too. Makes a big difference to the character of the vehicle.

Currently I think the mg metro box is a 3.2 it seems pretty good . 4th is slightly tall but some it seems to be a happy medium.

3.2 will be fine if it's supercharged.

So supercharged route.....which would you go for
Depends on your budget. VMAX is quite popular, however it is a suck through system.
3.2 final drive would be my absolute limit, 2.9 suits them well, and even the MPi 2.76!

is there a problem with suckthrough systems?

worth noting that the rotrex unit is a centrifugal supercharger (effectively it's a mechanically driven turbo), so available boost will be related to engine speed, whereas the positive displacement superchargers like the eaton types should in theory provide the same boost at all engine speeds

I now think the 7 port is not enough bang for buck compared to a sorted 5 port

I don't think so otherwise the BOV will be open on anything over tick over
