A couple of months ago I blew a gasket between my turbo and exhaust manifold....my bad because I didn't check the nuts which had backed off. Fixed that issue but then three weeks ago I noticed the car sounding more like a truck. Long story short, the exhaust manifold was somewhat loose and found that two bolts had broken off. I had torqued one off when we installed the turbo but these two that broke recently were at the other end of the manifold.

I had all the bolts replaced and during this found that the manifold itself is a little warped but with the new gasket and nuts/bolts, things seem to be fine for now. I will have to buy another exhaust manifold however

Are there stronger bolts/pins that can replace the oem ones ? Not sure if anyone else with an aftermarket turbo has had similar issues.

I suspect that there is a shearing effect going on during wot which may be causing this....just a guess.

I definitely am going to keep a close eye on them but I know I'm going to go thru this again and would like to do my homework before that day comes.

Any thoughts ?
