u can't use big port intake on a small port head.intake port diameter is different, and i think bolt pattern is different. better off just bolt a big port head on. or if u can find it, i think the 1st gen 4agze in a MR2 is big port.
there's also problem when u bolting a big port head to a small port block. i am assume u using small port ECU, so u have to disable the TVIS, trigger it to open all the time.
oh, and...check your pm. it's about the 4 spot brake again.
