i know ive seen a bunch of forums about putting on a 2.4 intake manifold on the 2.2 but has anyone ever thought of also putting on the 2.4 throttle body?

OrngBalt

yes. the original tester of the manifold did a TB swap as well. it put the car into limp mode because there was too much air for the computer. it read the excess air as a leak and a problem. We will not be able to put a throttle body on there until we have tuning

where is the best place to buy a 2.4 intake? and how does it inprove performance?

D4u2s0t

other people have said it hasn't. it may give you a few more PEAK hp, but all across the power band (which is shifted way up) there's a huge torque loss, whih means slower acceleration.

has anyone tried using the gmpp adjustable timing gear set with the 2.4 manifold swap totry and get some of the low end torque back

D4u2s0t

not sure. i haven't looked into it that much.

OrngBalt

you ever find out anymore about this?

slindborg

"we" in the UK seem to have done it sucessfully...

2.4 inlet mod although not sure if you guys are running ETB or MTB

Not saying this specifically to you but it makes no sense. The MAF sensor is made to measure airflow coming through. If it wasn't fit on properly and there was a air leak then that's something different but it shouldn't throw it into limp mode just because a larger throttle body is on.

Dunno who you're reffering to but it would be nice if you could cite who it was.

I dyno tested the 2.4 manifold for CED. I'll also say that the second part of that may end up only being true for the 05-06 because of the diffrent MAP and E16 computer.

You're right...

I'm glad someone gets it besides me

it will go into limp home mode, but for a different reason. your engine will get more air at idle with a larger TB, causing the ecu to flow a bit more fuel to help maintain a 14.7:1 idle afr. this however, creates more power at idle, causing the car to idle above 100RPMs, which tells the ecu that there is an air leak

I posted this in the other thread as well.

Look up what a IAC does.

Your throttle plate is closed at idle.

I know, I swapped a I-5 TB off a Colorado truck onto my car, and it would hold an idle after a littel bit and was super responsive, but over 20% throttle or so I got reduced power mode until I shut it back off. Has something to do with airflow tables that the car expects to see in relation to TB percentage, the car has a parameter for TB square area, so you need to inform the pcm if you are gonna be changing that. Just personal experience, I know that I installed it correctly, it was 100% electronic, because the car idled smooth and drove ok until you gave it a little gas, then it panicked.

NJHK

Exactly.

Car will idle just fine because of the IAC. Above that is a different story.

Your issue (just guessing here) might have been a difference between the cars TPS (Throttle Position Sensor) and it relating to fuel enrichment.

Right, the car was getting a LOT more air at a given, say 12% TB opening was flowing twice the air as stock, and the car was freaking out once it got past a certain point. Throttle response was incredible though

NJHK

Makes sense

yes it does fit and i has alright gains however i would only recommend this product if tuning starts supporting our cars and you can buy this at CRATEENGINEDEPOT.com
