    phew! man.. that kinda scared the crap out of me… I thought it a bit weird that there wasn't any mention of oil squirters in the haynes manual. That's a huge relief.
    8.5 custom arias pistons (.020 over)
    eagle rods
    t70 turbo (man was that a squeeze)
    38 mm external wastegate
    mild port/polish
    3 angle valve job
    custom intercooler piping
    twin external intakes with z32 maf
    rad moved back
    3" exhaust with only a resonator
    romulator
    420cc injectors
    custom body work, homemade oil lines and fittings..
    walbro 255lph in-line fuel pump.... and lots of headaches… lol

    On my set, there's never any piston clatter. Also, clearly, I had them coated at Swain, which isn't included in his price.
    this might sound stupid..but im new does this piston setup require boring…and how much if so?

    yes, too much for a vg30 block. should be fine on a vg33.

    consult your machinist.

    Kind of off topic a bit. About the oil squirters.

    Has anyone actually tried to put them in on a VG30E(T)? I was looking at my buddy Scot's torn down VG30DE and it just looks like they're tapped into the main oil galley. Seems simple enough to have the machine shop do.

    Also was reading up on the oil squirters a bit. The VG30DE(TT) all used a small diameter open squirter but the SR20 uses a small check valve squirter that only lets oil squirt above something like 25-28psi. I assume for when the motor is building more oil pressure due to higher revs aka racing.

    I'm about a year (fingers crossed) from tearing into my motor to do any hands on with this but maybe someone with a block ready for machine work would be interested.
