Thread: Manny's VET Open-Motor Surgery

I will go with that but the Mazwox head stud is 12.5 mm and that holding power is from being much wider. I would like to know how much more surface area it has over the stocker

This is what I did on the drag car 8 years ago. Remeber this was my motor and I put in 1/2 studs in the block. Mine just bottomed out with straigh threads.

Wider studs are way beter as they will increase surface area hold by alot.

the nismo studs for the gtir have the same feature as those aebs,

do the tomei, greedy studs have the same, never seen them ?

this came up before on sr20forum, think it was bigtoe who was emailing them at the same time as me, the guy at arp he was discussing it with was saying they had nothing to suit the application when given a drawing. The guy i was talking to was saying they knew of no issues with the sr20 studs, they are not designed to bottom out, 2-3 times diametre of thread depth is adequate in an ali head, but he did quote a higher torque than is noted on the packaging iirc (80lbft instead of 70lbft with moly lube)

dont know if bigtoe carrried on with discussing anything tbh.

The Jun Head bolts are the best to me.

They are like stock but hold way more power.

The greedy ones are great to, I saw them and they bottom out they do not have the shank on the bottom so full threaded all the way down the center is thicker than the ARP one and it is tried and proven.

Tomei head studs should be good to. Never used them but they make alot of stuff for Nissan.

Great discussion ladies.

Lance, do me a favor and step away from the CAPS!!!

your cometic head gasket is a weak link

Damn no love for me in the thread. De pinga!!








The head gasket in this situation had no issues.

did he find out why it was overheating while boosting? coolant seeping into the cyl?

a cometic has done that on an N/A motor don't see why it would be so hard to believe it would do so on a boosted VE especially since the VE cometic gasket isn't all that well made for a ve block

The blame goes to the ARP bolts. Head was being lifted when in boost.


Read the thread and you will see how/why. Alot of good info in this thread along with some high experienced people giving advice.

I don't think Cometic headgaskets are bad.

I think the only issues is with the 90mm HG.
