14B Bolt Sizes
 

Just took my turbo down to home depot looking for some bolts. Couldnt find anything that fit the threading/size. Anyone happen to know the sizes of the oil drain holes, and the sizes of the exhaust housing to o2 housing?

Also where are most of you people getting your small air filters for the turbo inlet from? Everything I've ever seen is too huge to fit my inlet?

8m x 1.25 amd 10m x 1.5 should be the bolts.. For the air filter the best bet is to get a silcon reducer.

i bolted my t-25 to my adapter plate using cheap strut brace bolts.(the strut brace pep boys sells for like 30 bucks)and for the o2 housing i used 3 rear upper control arm bolts and one castle nut from my stock front upper control arms on my 98 civic ex. i have so many bolts lying around from all the times i took parts off my car to put better ones on. after all this is home made turbo(recycle, reuse, blah blah blah)
