has any one used this stud kit befor, it seems like a better option then pining a motor.

Pretty much as a given, count on just about everything coming from GURU being A+ awesome. https://www.nopistons.com/forums/pub...IR#>/smile.gif



That stud kit will definitely work. It's advertised correctly, as well.

I've got 8 sets on backorder, 2 sets will be available next week if you're interested.



Ours are now comming with allen heads for easier installation and black oxidized( not pictured)...

Those will be better than tension bolts in that they will have less likelihood of snapping and falling out the back of the engine, but they will not do anything to "strengthen" the engine in the sense of preventing housing deflection like what the GURU Motorsports kit will do. The difference is your studs are only clamping the housings longways, which is not requiring any machine work done on those housings, compared to the GURU kit which requires reaming of all of the bolts' pass-thru holes.

So just making sure I have my facts straight.:

1. In previous posts you state" I have built hundreds of motors"

2. In this post " studs go in every motor I do"



Therefore: By power of Logic: https://www.nopistons.com/forums/pub...1047683664.gif



You have ordered hundreds of Stud Kits?



$434 Aus.[337 US] x 100 (We'll be generous) = 43400 AUS/33,700 US



Does GURU send you a Christmas card everyyear for being their BIGGEST US Customer?

there is a reason his rebuilds start at $3750 and he offers financing.



he only uses the best https://www.nopistons.com/forums/pub...R#>/bsflag.gif

Why not answer the question.



Please list some people you have built these "100's of engines" for



Please show us an invoice for all these stud kits.



HMMMM

Not totaly.



The 10mm stud kit is the same diameter as the stock Mazda through bolts but is made of a stronger material. Also, the addition of nuts on the ends of the studs instead of the through bolt allows for more accurate tensioning. This kit is approximately 30% stronger than the factory bolts, compared to the 12.7mm kit, which is approximately 70% stronger.



Sorry guys next time I won't be so mouthy.

Copied and pasted from my in the works webpage:



Studs offer precise torquing of fasteners over bolts. Instead of twisting a bolt to achieve a desired torque reading, studs are stretched. Twisting creates friction, friction gives false torque readings, and the end result is a lower actual torque reading. Thus clamping force is reduced.

These studs are made from far superior material, applied clamping force is increased even with the same amount of applied torque over bolts. Stud expansion is limited, while inferior oem bolt material allows them to stretch, and reduce clamping force.

Studs are easier on front iron threads, OEM bolts cause wear and tear on threads. OEM bolts can tear front iron threads out.

Acoustic harmonic and resonances problems are reduced from the superior material used in stud manufacturing.

Engine expansion and movement is reduced with greater clamping force, a must for turbocharged or high horsepower engines.



Head studs cut down on piston heads moving around, why don't you think it would be the same for a rotary?



p.s. John, iceblue has ordered studs in the past from me, along with many other shops in the usa/puertorico,uk, etc..

Hundreds?
