ElmerRacing Billet 4b11t Race Block Machining
Machining the ElmerRacing 4B11T (evoX)-compatible billet race engine block! Prototype was tested back in 2015 by Riku Tahko, during the whole FIA RallyCross EC series + test sessions. Upgrades for 2016 (as shown in video): Mass reduced 1.2kg Multiple variations available [bore: 86 or 90mm] [mounting: stock or tilted race version] Direct link for more information:

100 psi of boost, 11,000 rpm and 1900 horse power - This billet block can handle it
Bullet Race Engineering are world renowned for their billet engine blocks which are seeing use in both drag and circuit applications and breaking records everywhere. In this video we find out what goes into designing and building a billet 4 cylinder engine block that can cope with 95-100 psi of Boost pressure, 11,000 rpm and 1900 horse power.

4g63 Block Oil Gallery Mod
This modification is intended to improve your 4g series engine's oil delivery. People frequently discover large chunks of flash in their engine's main oil gallery. It's because the galleries are part of the cast, they're not machined into the block. There is also a very rough sharp edge where the main oil gallery is bored into the block, and oil must make a slightly greater-than 90° turn in order to begin its course to the parts it lubricates. Both of these conditions cause turbulence in the oil flow. My goal in this video is to eliminate as much of that as I can. This is a cheap and easy modification if you have the tools, and the patience. Any engine with cast-in oil galleries could probably benefit from this. Be careful not to cut into the high pressure oil gallery or else you will circulate un-filtered oil to the #1 main, oil pump, and rear balance shaft. You will also deprive the rest of the engine the oil pressure it needs to operate. So in short, punch a hole in that and it's trash. I did this my way, everyone may choose to do this a different way. I just wanted to make this video to raise awareness. Also, there's a great thread on DSMtuners about this. Pictures and everything. Written by a machinist and friend of the DSM community. Go give him some reps because he's posted a lot of great info about the DSM oil system over the years. ng-mod.html
