I bought an egr block off plate for my s14. Got my friend to make me a few copies. I have 6 extra, I thought I would share. $20 shipped. It mightwork on de s13 but I am not sure. They are plasma cut high quality stainless steel.
For those of you who don't know. This will bolt onto where your egr connects to the manifold. This does a few things... give you a few more horses, you also loose a little milage, it can also screw up your AF if you don't have some sort of correction. I am not responsible for anything you do to your car.
Send me a PM or catch me on AIM.

 

Nobody? $20 price includes shipping and paypal fees.

 

Still got these if anyone wants one.

 

these can be had for ~$15 shipped on ebay.

 

I don't see any on ebay, for any nissan. I looked everywhere when I needed one and couldn't find any.
