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'm not that fammiliar with the 4cyl's Don't think it would make a whole lot of difference.

What are the HP ratings :

US to Jap 4cly ?

U.S. 118HP.....JP 170HP We get screwed

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.

Good point Darin, will octane boost work? BTW did you get all shook up today ?

BigProbe · 02-28-2001, 21:33

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!
