yea i just found that aswell, i would go for something like this,
http://cgi.ebay.com.au/T2-TO-T4-TURBO-FLANGE-ADAPTER-for-INTERCOOLER-CARS_W0QQitemZ370126270021QQcmdZViewItemQQptZAU_Ca r_Parts_Accessories?hash=item370126270021&_trksid= p3286.c0.m14&_trkparms=66%3A2|65%3A1|39%3A1|240%3A 1318
but even a 5yo can weld that up, plus i want there to be a SMOOTH transition from round to rectangle, not the way it is in my link,......which would =turbulent flow, increased heat, something that isnt effiecient!
ill continue looking for now
