    • Hey mate, thread dredging hahah To answer you directly, yes I had my itbs oversized and custom butterflies etc made by EFI Hardware in Sydney back around 2017-2018 if memory serves. My setup had a vast amount of other changes too though, so no direct comparisons unfortunately. i went from oem itbs, HPI manifold and internal gate hks 2835 pro S; to 49mm itbs, cnc port matched Nismo plenum, RB25 Neo lower runner adapter hand port matched, r31house v2 Takoashi MAX equal length twin scroll manifold with twin 38mm tial gates and a FP HTA3076 with 1.01ar twin scroll real hosing. feom power Fc to a link fury wired by 12volt, r32 gtr fuel tank conversion with frenchys twin 460 / surge tabk fuel hanger combo kit, 1659cc injectors, full 4 inch turbo back stainless exhaust, Z34 6 speed, Tomei 2way with 4.3 final drive and a ton of other shit. ive posted elsewhere here with complete run down, but here's a graph from its initial tune with no boost control on, 20psi gate springs only and e85.   7542AE72-DA92-4E0B-8660-B0940FEA7F24.mov

    • Slap it and say it ain't going no where, you'll be fine.
    • So the whole rb25de neo setup was a tiptronic setup and i swapped everything over to my rb20de neo setup and yes even the cluster of the rb25 was swapped over. 
    • and I thought size mattered 😝 At this point I may either pray to the Afterpay gods and get a torque wrench or attach a water bucket to the breaker bar. I appreciate the help though 🙏🏾
