Looks so cool and well thought out!
That 650 is a made up number. There is zero data backing thatMileage estimates are 100k plus. The forged pistons are gonna wear the bores more though. From my understanding engine warmup is mandatory, not optional on this setup. The upsides are worth it though. IMHO the Juke have a strongish stock piston but the rods are more questionable. I’m not taking any chances in case I get a boost spike or detonation. Plus, the forged pistons and rods cost maybe $500 more than the OE rods and pistons, not that much of a difference.
It’s very likely the 2J upgraded rods could be reused on another rebuild, maybe just requiring a piston swap. They are rated for 650 whp. The stock parts I don’t think that’s the case. The V1 engine blcok can easily handle 1 engine rebuild due to the thicker iron bore liner thickness.....possibly 2 rebuilds. The V2 engine block liner is much thinner. Once it’s out of spec it’s a throwaway block.
Yes, it's a problem. Exactly, furthest cylinder gets rammed with more airflow.....basically it's intuitive. The airflow can't make the inside turn without recirculation and lower pressure. That little bit pressure difference from inside turn to outside turn really messes with the flow balance across to the ports. HVAC systems use turning vanes........but there is a much more elegant solution to the problem without adding any measurable restriction or complexity.so is there a problem with the difference in relative velocity between the ports? Maybe not at higher boost levels, but could this make maybe cylinder 1 (furthest from throttle body) always run lean and cylinder 4 (closest to throttle body) always run rich? Just thinking about air being forced into a cylinder and anther being starved due to velocity of the air.
