3S-FE Intake Manifold on 5S-FE, up to 40 hp?? specifics.... Options

[Silver94CelicaOw...]

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.

What you have to look at is the cfm of the size of the manifold tubes to see if there are bigger.

The 3s is a 2l while the 5s is a 2.2l there. It sounds (base on torque figures), that the 5s manifold should be bigger or the same. If 1mm, forget it.

What you should try to do is to either buy some throttle bodies or look at force induction which is fairly cheap done properly. The gains to be hard with a 3s is a waste and should be put into a small turbo set with 2-5psi of boost.

All that is needed is a Apexi SAFC II and a boost controller Apexi AVC.

My small advice.
