• ^^Hahn Racecraft 20G is used on the whiteblock I5 by a few people, not that much more effective than a big 16G though it would seem, although that spins backwards and would have been much more of a pain in the arse to package.

    I dont know much about them to be honest. It has the same flange as the IHI and is more reliable, it would seem. So they were the main reasons of sticking it on.

    It had to be clocked like the IHI and the actuator bracket moved as they were obviously never destined for this block.

    There is a guy who has gone through 16g, 18g and 20g on a TT and got the most power (407bhp on a 1.8L) with the 20g. Hence our early estimations of power.

    I just want to break 400 as it looks good in the for sale ad!
