Got the second wastegate welded on today:
Oh and the oil cooler and power steering cooler turned up (actually meant to order the longer version of the PS cooler but this tiny one arrived and I'm wondering if it will do or if I need to swap it for the one that's twice the length). The oil cooler is quite large (34 row) because I had a 25 row on this engine/turbo setup when it was in the 350Z and oil temps did get a little high. Looking at the recommended size for oil coolers for various HP levels on one of the oil cooler manufacturers websites, they actually suggested an even larger one than this, but I think for the sake of space I'll try this one for now. Its not like the old 25 row one was terrible for temps, it just could have been a little better.
