So further to my fun and games in here.... http://www.300zx.co.uk/forums/showthread.php?168311-warning-to-zedheads-with-the-motors-out whats my options with regards to new or recon tubs and wheres best to buy??

I had exactly the same issue as you Brian, fresh engine build with same tubbies, run it in, up the boost and... Pop! The exchange rate was v good at the time so I went for the Z1 GT525's, not ovally laggy but a fair improvement over stock. The difference on launch isn't massive but the GT525's don't run out of puff towards the top of the rev band like stock so pull a lot stronger through each gear. Worth a butchers...

a pair of gt2554r ball bearing would give you enough puff for 480 hp and arnt silly expensive i can get these straight from garrett in around 3-5 days if you want a chat give me a shout on the blower happy to run through all turbo options and spool up times with you
