Turbo manafold/turbo seperation

s13driftertb · Post by **s13driftertb** » Tue Nov 20, 2007 10:03 pm

So on the way home from the Gymkhana event my turbo started coming free from the manafold. I got home and started tighting up the bolts but I've got them as tight as I can and it is still leaking. Could this have messed up the turbo gasket to the manafold?

If so what is the U.S part? 300Z TT?

yes, the gasket is most likely toast from the turbo coming loose. get a gasket for a 300zx and call it a day. if you can, find some all metal self locking nuts too. they're not a 100% solution, but they can help. also adding flex pipe to your exhaust can be a big help too.

if you can weld and are happy with your current turbo manifold set up you can tack the nuts after you tighten them

Another way is to "damage" the threads just above the nut by hitting them with a chisel. Doesn't take much for the nut to hold down, but it'll take a little bit of work next time you want them to come off.

what he said...

I'm going to put the stock nut lockey thingies back on. I used the hardware that came with the Megan manafold...

oh, on the Flex pipe. I do have one. current set up is...

Megan, manafild to turbo, to Megan turbo out to Megan down pipe (with flex) to megan test pipe to Greddy knok off cat back system.

I got all of the megan stuff together as a package for $400 that is why there is so much Megan stuff.

I'm hoping the Mafold doesn't crack, but I have sold engine mounts (hard solid plastic) and Transmission mount (alum) All MMR-Racing (thanks Patrick)

BTW thanks for the help guys!

the manifold will crack. it is just a matter of time, not trying to say it will happen tommrow but at some time it will happen. make sure you put the braket that bolt the turbo to the flange so that pipes are not holding the weight of the turbo. that is the main killer. and having a flex pipe in the down pipe is spose to help a lot too.

so Nissan is saying $24.74 for this little gasket, does that sound right? anyone know the part #?

UPDATE...

just got back from the Hippodrome Nisan dealer down town, good to go.

also xatracing.com almost always has that in stock.

another preventative maintenance thing you can do is like icandrift said, metal locknuts, plus lockwashers will help.

or you can be a baller and run vband....on a megan manifold.

i wish i had a ka-t so i could have a vband on a megan manifold, then i would be a cool kid

what is "vband"?

I had lock washers and locktight and they still came off.

also that wouldnt work that well on the manifold to turbo unless you are running a small turbo. you can also add bracing and stuff. locknuts and stuff should do the trick, i just dont like welding because thats a pita if you have to add/remove something.

you can also do like icantdrift said, and put a lsjuan in it.
