    Latest development in the super charger vs turbocharger series.

    As much as I'd like to flex my tig welding skillz and tryout the new machine by making turbo manifolds this has tipped the balance and made me want to go supercharged 998 even though turbo 1275 would cost me less and make far more power but this is more about a nice reliable street car.

    Thinking 998 a+ block (I have a 998+ engine going spare anyway) rebored +060 and decked, forged pistons (dished) and rods, all balanced, bigger valved 5 port head, kent 276 cam, 1.4 rockers, duplex timing chain, podifold, eaton m45 off a BMW mini blowing through a metro turbo HIF44 carb and plenum, intercooler off a renault 5 turbo, LCD exhaust manifold and single box rc40 pipe. Megajolt ECU.

    Rebuild gearbox with straighcut gears from swiftune and a crosspin diff.

    Gonna terrorise everyone by sounding like I'm constantly in reverse because of the gears + the wine of dat supercharger.

    Edit: not looked at suitable dump valves yet so suggestions welcome.

  • If you're doing all that work, then surely it would be rude not to add a quick BMW K-series 16v head swap at the same time. Make the most of all that 'charged air.

  • I didn't feel it'd be worth it for a 998 as it adds loads more complication, I'd need custom manifolds, mounts, conversion kit, cams, and it'd take up loads more space making everything a bit hard not to mention the cost. looking at nearly 2k for that conversion without the forced induction bits.

    I did consider a 7 port 8v head but I don't think even that would be worth it as it'd put the inlet ports facing forwards and that makes it hard to fit a plenum in the front of a roundnose mini and for once I don't really fancy bits sticking out the front. Gotta keep it stealth.

    Money no object mini would be a 1275 bored and stoked to 1460, KAD 16V head, twin turbos and EFI... but unless I win the lottery and build a sick machine shop that won't happen.
