93civicjaydm

Ok. I have a 93 eg with a Jdm h22a in it. I have searched around and could really find my answer. I want to do a aftermarket throttle body and intake manifold but I was always told there is not enough clearance to put a aftermaket intake mani on it. Is this true?? If not can anyone tell me me what will fit and what won't. I have also heard of using a s2000 intake. Is that even possible either.
Thanks
Mike
