HP for a Atkins street ported 13B?
Hey guys, I saw a RX-7 for sale here locally that has a Atkins Street ported 13B in a 87 RX-7...Can anyone please tell me what they rate Horse power wise?
Any other info about them is great!
Thanks much!

why dont you just contact Atkins and ask them your self, that would be alot easier than asking here.

From what I have heard on a N/A a "normal" street port will add ABOUT 25rwhp. A healthy STOCK s4 na will pull 120-125 on a dyno.
