Anyone out there know if the J-spec intake manifold is worth puting on my 96-SE. If so how hard are they to install. Will I need a ECU upgrade. Im still kinda new at the whole mod thing. Any help would be great

Why don't you just take it to a shop and have them port and polish it ? I'm almost sure it would be cheaper.

A good Porting job should give you about the same gains as the J-spec manifold. Go to a junk yard and pick up a used one and have that one done up .

What about the Variable Resonance Induction System.
Isnt that a good reason to do the swap..does it make a real differance in performance?

i don't know much about the J-spec 4cyl. But the kl-ze2.5L you reach max horses and tourqe around 6200rpm. So I would guess it would be higher for the J- spec 4cyl. as well. Do what the Jackson racing did to the Focus. Put in bigger valves and a turbo, it from 130 horses to 300.

Remember, those jspec #s are listed w/ the jspec ECU and 110+Octane fuel. Dont expect more than about 120-130 hp at the wheel from that motor in a US - spec car.

I dont know of any octane boost that will increase gas more than a couple points at most. 112 octane is about $5/gallon...

Yeah, we got rocked man.. but all is well. :) we are all safe!

I heard that the J-spec intake manifolds that have been installed on the 2.0 just have the VRIS things tied open. Go with a port and polish. I recommend that Raw Power does it.

Why not go with the J-spec intake, AND port n polish it?! That way you get the best of both worlds!

170hp!? Wow, not bad for the little 4!

WOW lots of opinions, thanks for the info. I'm still not sure what I'm going to do. I want more power. 118HP is pathetic these days for a 2.0L DOHC. I get spanked by quite a fue cars on the road.
