Anyways to "need RX7" - Thanks for the compliment...It's crazy to port the Cosmo motor after you compare the 13B-RE intake runners to the 13B-REW and S4/S5 intake runners.There is a quite noticable difference in size between all the other motors. Anyways I could have just left it stock but me being me I just had to have JR Fabrication put a large streetport in search of extra power.
