Its alot more difficult but the plenum should be tapered towards the rear. How you have it now will be feeding the rear cylinders a shit ton more then the front. All the air will rush to the rear and having the same volume directly outside the rear runners will ‘force feed’ them. A tapered plenum helps reduce this effect. ---

That plenum would be fine. I know there is a difference between the s13 and 14 mani, but I think its in the lower half. Either way it dosnt really matter. What i was talking about is having the plenum tapered such as: ![http://img16.imageshack.us/img16/1734/picture093l.jpg](http://img16.imageshack.us/img16/1734/picture093l.jpg) ![http://img16.imageshack.us/img16/5412/picture096h.jpg](http://img16.imageshack.us/img16/5412/picture096h.jpg) ![http://i148.photobucket.com/albums/s25/boostin50/DBPics105.jpg](http://i148.photobucket.com/albums/s25/boostin50/DBPics105.jpg) As opposed to ![http://www.ka-t.org/tech/intakemanifoldbasic/im5.jpg](http://www.ka-t.org/tech/intakemanifoldbasic/im5.jpg) ---

haha for an old datsun, more power to you. It gives it that nostalgic vibe. But I’d never down grade a car that came FI to a carb setup. ---
