Lucas 244 Report post Posted November 16, 2017 This is one of the best performance upgrades, that just a little over £400 can get you! Do not hesitate and snatch the kit while you can - there's only 1 left. These new CNC machined power blocks from billet 6061 aluminium, sit between your cylinder head and your intake manifold, purely to get longer intake runners. The lengthened intake runners increase the volumetric efficiency of the engine which gets you an extra 19 horse power and 15lbs/ft of torque! And on top of that, the torque dip has been narrowed up by 300RPM on a completely stock FA20. As you can see on the dyno graph in pictures, torque went from 155 to 170 as well as BHP went from 187 to 206 All this works with all aftermarket tunes, exhausts and intake components. All that tested by Crawford. I personally think, that this would be very successful with Tuning Development's Tune https://www.part-box.com/b0400-crawford-big-power-blocks-intake-manifold-spacer-toyota-gt86-subaru-brz-12-17?search=crawford spacer&description=true £367.15 Share this post Link to post Share on other sites
