  1. Romandayf I was pondering direct injection as I cant get 1urfse/2urfse's out of my head, what is the main reason you abandon the DI? Cos its a bitch or? 

    Some very light reading suggests benefits mixture (efficiency and power) and Im sure something talked about charge cooling too, or is there really a need to run both DI and port injection that Im missing and so becomes a big faff?

    Or is the main reason for looking at these toyota DI n/a engines because they typically have the higher compression as a starting point

  2. pistons supposed to be reasonable, some internet experts rate the standard fg xr6t piston over the FPV F6 semi forged one for bigger power over stock (although its heavier, i cant recall if this was just FG or same for BA/BF). Aftermarket forged obv get to even bigger power. cant recall what the internet says stock rods are good for but i thought so long as not mk1 BA xr6t small rods then unlikely to turn to bananas until seeing much more power than stock, didnt think rods were any more limiting than pistons but maybe they are??? i guess all depends on budget and goal for power/skids for the kids

  3. I went down the rabbit hole on them once and they are an aisin AY6 (as opposed to an AZ6/J160) 

    They are the same box as in a manwel VE SV6 if anyones driven that to compare, its apparently supposed to handle a reasonable amount of torque. I dont understand fully yet but it says it handles more torque through a different input/output shaft configuration which means it spins the gears faster, so I am guessing might be happy on a lower revving torquey motor but might not like higher rpm situations - speculation only.
