So a while back, this was sorta brought up but i want more specifics on exactly how to do it....I think its a good performance option for the 5s-fe if its true. I remember 1bwilson said that you could take the intake manifold off a JDM 3s-fe and a 60mm throttle body and you could get gains of around 40 horsepower. I've searched everywhere online for more info on it, and havent seen much of anything. I would just like to verify that claim, and if its true.....

a.) Exactly what parts do you need to get it to work? Would the manifold be from the Curren's 3s-fe??
b.) Would about a 40hp gain be reasonable to expect?

Just a little more knowledge on this would be greatly appreciated. wink.gif

The 5sfe manifold is said to make the 4th cylinder run lean due to something about the pengulim (sp?) I dont know. I have read this on the mr-2 boards and also been told it from Nuke on c.net. I know that Jim snoodgrass has one on his 2 along with a 65mm TB. There was a post about this over there so I'll try to find it and link it to here.

I can't read the post yet...not registered (will do later) but if it's an air/fuel thing, about running lean/rich or something... it's not gonna add 40hp... Like west_minist said, a SAFC should be able to adjust and maximize the mixture without the mechanical hazards.
I'm gonna assume this originally was intended as a head swap from a 3sge and not a 3sfe or an intake manifold swap. If i'm wrong... well... I just find it hard to believe that swapping economy "FE head" parts for economy "FE head" parts is gonna make an engine more as powerful as its performance counterpart.
