Has anyone used one? How is the fitment? Any of them breaking?

 

I've heard good things about them

That's in my plans for my sohc.

 

I've had my hands on one. I mic'd the clearances and everything. Everything is right in spec with the honda service manual. I'm also running the 3/5 kit in my trans and I love it.

I've heard nothing but sucess stories about them.

 

I have run the 4.9 in a 260+ whp B series and it held up fine.

 

How was the installation?
Apparently the Mfactory kit is different than the ATS, ie. no 1st JDM gear?

 

We have USDM fitments available, hence no JDM parts are required
