99 Manifold on a 01

I am Frakk · 05-03-2004, 04:29 PM

I keep on hearing that a 99 Manifold is very suitable for the WRX injectors I have an 01 w/ the stock injectors and I am running about 7 pounds of boost I know that my injectors are running at well past their operating range... I was just wondering if anyone has done this on their ride and what are the issues if any did you encountered when you did this change over?

Thanks

It'll work on an 01 with a little drilling work. There's a sensor that needs to sit on top of the manifold that needs 1 holes for the sensor and 2 for the screws. The screw holes need to be tapped too. Also, buy new manifold gaskets since the old ones can tear easily.

I would imagine I would need to upgrade my fuel rails to fit the WRX or STi injectors correct?

maxiav · 05-04-2004, 11:30 AM

Are you trying to get WRX injectors???..... wouldn't it be cheaper to just buy injectors and fuel rails than changing your intake manifold?

I am Frakk · 05-04-2004, 11:40 AM

or I can do that...as far as I know though or to my knowledge I haven't seen a manufacter that makes fuel rails and injectors for the SOHC EJ25...do you know of any? if so it'll be greatly appreciated...

maxiav · 05-04-2004, 12:27 PM

I have Vishnu fuel rails and RC550 injectors that fitted beautifully in my car. You need some spacers for the fuel rails, but I believe Vishnu sells those too. NO LEAKS!!! Perfect fit

The benefit is to be able to use WRX aftermarket injectors or use the WRX injector mod and you'll have fuel for just about any turbo. Also, you won't have to hack your injector harnes or run low impedence injectors when you get bigger. You can use the RS rails with the WRX injectors.

i think you throw a cel if you change the manifolds for the air assist thing in the 00 injectors being disabled, i think kaos200 told me this. I dont know if theres a way around it, its the only thing stopping me from getting a 99 mani cause i dont want a cel constantly

Would a CEL damage the engine or make the car not run reliably? or is it something that I can live with?

Derk1127 · 05-04-2004, 07:11 PM

i think its something you can live with but if you live in a state with emissions testing youll fail because of the cel

I am Frakk · 05-05-2004, 11:52 AM

Like California? I'm running straight pipes so right now I am not what you call street legal, as long as it works I think it's fine with me...

Derk1127 · 05-05-2004, 05:50 PM

just anywhere that plugs into obd 2 ports during emissions testing, i know WA does

You are WRONG sucker!!! The map sensor is also a inlet air temperature sensor.

akcel · 05-06-2004, 06:06 PM

but will u see a CEL? NO

I am Frakk · 05-06-2004, 06:17 PM

I see said the blind man...

SubaFastR · 05-06-2004, 06:18 PM

doesn't mean it's running right.

Derk1127 · 05-06-2004, 06:38 PM

lets just say that he drills the hole for the map and he uses a oem ecu is there a way around the air assist cel? i havent taken out my injectors or anything but is there a way to keep it connected but just not have it do anything just so the CEL wont pop up?

akcel · 05-06-2004, 06:42 PM

i denno i havent tried it...kevin?

SubaFastR · 05-06-2004, 07:41 PM

take out the cel light bulb.

akcel · 05-06-2004, 09:28 PM

I think the cel adds character...it was my first mod ;P

Damn, not something I wanted to hear. Do you know how important this is to the Links functionality?

Drac9 · 05-07-2004, 12:57 AM

You can wire in a gm air temp sensor in the intake pipe to your turbo instead.
