Turbo to downpipe bolts
 

After 5 of the double threaded bolts for my t25 which connects the turbo & exhaust downpipe, know i can get them from Nissan but not willing to pay just short of £50 foe 5 bolts any ideas where else i can get them?

My local motor factors stock loads of different Bolts/Studs and Nuts. Might be worth trying one around your way. Or maybe an Exhaust fitters?

or just get a bit of M8 studding, im sure they use std M8 thread in the turbo housing, it dont "have" to have the shank bit in the middle, just measure the depth of the hole, add enuf for the nut washer and elbow, and wind them into the bottom with some locktight, leave for a few hours, and then fit the elbow and nut, should do the trick, but check first that the thread is M8 in the housing (just in case im wrong)

Thanks did have that in mind but was worried that the high tempeture may cause then to seize or break?

get high tenstile studding, or you could use high tenstile bolts and cut the heads off at the right length.
