Turbo to manifold bolts

Was just wondering if anyone knew what size bolts I need to replace the bolts and studs that go from a 2g manifold to a 14b turbo.... I could always pull one out and match it up just wanted to save a trip... car is 20 min from where I am... thanks

It should be all bolts. You can't just use regular bolts, they are hardened steel. Buy them here: Click half way down the page.

i would replace the stud with a bolt.

They are m10 x 80 1.25 mm thread pitch.

I've used hardware store bolts for short term repair, but definitely but the real thing from JNZ, or if you can find them, grade 10.9 bolts.

i also got some pretty neat lock washers so that they never come loose. Might wanna look into that as well

 

Thanks thats what i needed to know.... can't just use grade 8 bolts? Or is 10.9 the metric equivilent? Was going to replace the stud with a bolt anyways.... thanks for the help

10.9 is the metric equivalent. I HIGHLY suggest just getting the OEM hardware from JNZ though.

I used regular grade 8 hardware one time in a pinch and after about a month of driving(forgot to change them out) one of them broke at the threads and the other were super brittle.

you can get ARP Chromoly Turbo Bolts for not much more than stock bolts

^ I have the ARP bolts in mine, but I'm still JSB so no review. It looks sexy though! /ubbthreads/images/graemlins/grin.gif

I would stay away from the ARP hardware. When I was first getting into DSM's and the 4g63 motors I ordered the ARP hardware from FFWD Connection thinking they were the best available. I soon found out that they were not, they seized up and stripped out a s16g even with the use of anti-seize. Since then I have never used anything besides OEM hardware and haven't had a problem since.

two:
- that's messed up that grade 8 failed so fast.. was it purchased from a reliable source? I'm no metallurgist but it just doesn't seem right
- ARP: great head studs, do not buy the turbo bolts. I broke 4/4 on mine in the housing

 

[Muskrat]

^^ I'm assuming he meant metric grade 8.8, (really Class 8.8). It's equivalent to a US Grade 5 bolt.

 

[jepherz]

Same experience with the ARB turbo bolts; I've had them seize up and strip out as well.

IMO, turbo bolts are almost a maintence thing. It's less of a headache to replace all four every 10-20K miles than to have them break or strip out.

I got nothing but bad things to say about the ARP turbo to manifold bolts, they are a waste of money. I reused the OEM 20 Year old hardware and they held up pretty well /ubbthreads/images/graemlins/smile.gif

 

I just reused the stock bolts, can't find a quality enough bolt in town to replace them. thanks
