Did it end up being an improvement, R34SR? Seems like a good deal.

Don't know yet, still haven't gotten to finish my build and tune on current cast manifold....I want solid numbers and logs before I switch so I can share real world numbers.....this was just too cheap to pass up as a backup.

Nice. I know that setup has been around for awhile but usually twice that price. I had the obx t25 manifold, nice build but the turbo flange was warped and a weird angle to making the downpipe was a pain

Just wanted to give an update, I was going to use this full setup with my 4 bolt holset hx35, my plan was to ust remove the 5 bolt flange from the downpipe and weld on a 4 bolt... but upon removing the flange from the downpipe I realized the piping looked kinda narrow... Measured it and it was barely over 2"....no way in running such a tiny ass downpipe.... So I scrapped the downpipe and I'm currently fabbing my own.
