I am looking into getting a new engine mod.

Should I go with a Magnum Fuel Rail from RRM or the throttle body from RRM?

Which one will gain more performance?

The fuel rail will look better under the hood though than a stock looking throttle body.

 

Throttle body, thats what I got and it works great. I'm gonna get a bored fuel rail next though, with all the new air you can definitely feel the engine start to struggle at higher RPMs.

 

The throttle body will give you more noticible gains. I've had my fuel rail for several months now and there isn't a very noticible increase in power, just smoothness and reduced throttle lag.

 

Sweet. So you can actually feel a good amount of power gain with TB?

Do you have a header? I've heared someone talking about the CEL form the header going out when they put the TB on.

 

Yeah I got a header, and yes the CEL went off and stayed off when I got the throttle body.

 

No question - TB.

The fuel rail is a support mod. The TB is a go mod.

 

Buy me one Doug That way I would have something to play with on boring days like today.

 

Hey, I need to buy myself a TB.

Since you're a machinist, you could bore your own fuel rail, I'd think...

 

Alright after thinking, I am going with the throttle body.

I will probably still get the fuel rail after the throttle body.

 

get the throttle body, im not sure but you probably wouldnt really need the fuel rail unless you were going turbo.

 

Well, the fuel rail does help, you can feel the car struggle at like 4000 RPM and higher.

 

o, i wasnt sure, i just know that rrm advertised it as a "must have" for turbo'd lancers. ive never really felt mine struggle at 4k and up, it just has a slightly difficult time going up some of the steeper hills in my area.

 

==================================================

Pump:

Yes, get both. Even N/A can feel the difference of the fuel rail.

But get the TB first.

 

Question.. Does the TB fit with an aftermarket air intake such as Injen SRI?

 

Yes. It's a stock TB, but RRM bores it out so more air can flow through. But the connecting points are still stock.
