so besides the obvious 39mm wasgate size im thinking about buying a manifold but it only comes in 39 or 46 mm
my tial wastegate is 38 am i screwed and have to buy another 1? i dont want to hack in to a expensive manifold

 

i may be wrong but the precision 39mm is the same as the tial 38mm

 

Pretty much, there are small difference but overall they both do the same job. Precision 39 bolts to a 38mm flange. We have them in stock if you need a wastegate fyi.

 

sweet wasnt sure if my tial 38mm would work or not
