anyone know what the thread pattern is on the "50 trim" china turbos? i put in some m8x1.25 or something and they seem loose, anyone know for sure whats supposed to go in the downpipe bolts?

i think there a standard bolt like 3/8 by 16 or 1/2" by 13. all of the turbos i have owned have had standard threads

Buy suggested bolts and see which ones fit

HiProfile · « **Reply #16 on:** February 23, 2010, 05:08:54 AM »

If the threads are wrong, they will only thread in 2-3 turns with your finger. If you manage to strip/crossthread the threads with your fingers, the porn industry needs your strong hands...

There will be course, fine, and "Honda" in case of bigger metric bolts (very fine). If a Honda bolt doesn't fit, which will be either m10x1.25 or m8x1.0, try the next thread pitch up. Just remember, CDM = whatever the fuck they had tooling for. No QC & non-decerning customers = no real standard.

Why don't you take the turbo to the hardware store and buy the bolts? Walking around with a turbo housing = bad-ass.

Quit being a faggot. Either buy a variety of bolts and return them if you don't need them or take off the turbo. I can't imagine taking off the housing taking more than an hour or so.
