hi, i am running a fully built b20vtec setup and its making 226whp. I currently have a jdm itr intake manifold and a stock b16 throttle body. Im replacing my jdm itr header with a knockoff hytech header and i need to replace my intake manifold and throttle body to try for more power. Any suggestions on a setup b/c i been searching and theres not to many intake manifolds bigger and better i was also thinking of itb's but my tuner doesnt like them so im trying to stick with 1 throttle body. Any one use the obx itb's at all and if so how are they? Any how bout an edelbrock victor x intake manifold it seems affordable and def. bigger than the itr, please any suggestions are welcome im trying to get it back on the dyno by next weekend and hoping to make 240's possibly 250 on an all motor b series.
