thanks

 

Not a huge change, but noticeable.

 

I have 1 left over if you looking to buy it.
PM me if you want more info.

 

I just reread your question. I purchased the gear from lazi and had it shipped to Mazmart. They built a diff for me and I did a core swap with them.

 

Take the diff out, take the gears out put the new ones in.

 

It's not quite that easy.

 

Be prepared to lose some mpg

 

I know.

 

the link has an outdated thread. could someone provide me with the link? kthx

 

You also need to work the spacer they give you in order to reach the perfect fitting.
It is the best mod you can do while staying NA if you track your car alot, otherwise save money for something different because it's not an easy install, it's expensive and you can lose highway mileage.
If you want to do it anyway buy different nuts for feed's one are not very resistant and some of us had to tear the diff. apart again to change them.

 

Thank you. I have been under the understanding that the install requires specific knowledge regarding spacing & torque. It also requires special tuning knowledge. I just need to find out as much as I can about it, and then find the right individual to pay to help me do the work.
