exhaust studs

[ditchdiggerjcf]

What size are the exhaust studs on my 91 3.0 engine. A thread from a while back talked about buying new studs or bolts from NAPA to replace the factory studs. Is the NAPA stuff any better?

I THINK it was M8x1.25. anyway get the early 300zx turbo studs they are stronger and less prone to breaking.

Napa should have them If you look up by 84-87 nissan 300zx turbo.

Yes, the are M8x1.25 and the factory studs were weak, almost anything is better but the ones for the 300zx turbo are the right thread, length and are sufficiently stronger.

Nissan issued a TSB and provided revised studs

check the service records to see if you have the revised ones before you go spend the cash

while on that same topic, I read somewhere on NPORA that the 300ZX Turbo studs that we need are:

 

 

I looked for these online and found them at www.nissanpartszone.com

However, if you simply SEARCH for them, they will be reported under Nissan Quest:

 

 

On the Pathfinder page, those same studs were highlighted as the revised# for the WD21:

 

 

 

I wasn't able to find the Nissan Part Number for the 300ZX Turbo studs on that website though

I used stainless hex head bolts, but if I were to do it again I'd use the ZX studs simply because its easier to line up the exhaust gasket when bolting the headers/manifolds back on. You have to hold everything in place while you screw at least two of them in when using the bolts. With the studs, the gasket and exhaust will hang on them while you nut 'em down.

Will surely do that

 

But is the 14065-V5004 the correct OEM number for the "revised" Pathfinder / Nissan Quest or 300ZX?
