Any way to change from 4-bolt to v-band? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

NickS14 · 06-01-2015, 02:54 PM

So, I've bee having an ongoing issue with my downpipe bolts wiggling loose from the turbo manifold, I currently have a 4-bolt patterned housing bolted to a Megan Racing downpipe. My question is, is it possible to have that changed without buying a whole new turbo exhaust housing? Or does anyone have any suggestions to help the issue...

I've had all 4 bolts work themselves out and almost lost my entire exhaust one drive because of it... boiled brake fluid... not fun...

cutting the 4 bolt and welding a v band

Yeah, easy to do on the downpipe side, but not so much the turbo exhaust housing...

??

And get a flex section in the downpipe if you don't have one already.

Downpipe has a flex section.

And that looks to be what I need, however it still bolts to the downpipe and turbo... I must be missing something...

bolt this on and tack weld the bolts. Or you could get a vband turbine housing for your turbo, that would be the more expensive, but better route

All hardware is Grade 8, still work themselves loose even with thread lock... I think I'm going to get the adapter and tack the bolts, just don't want this to be an issue any more
