Spyder Intake Manifold Swap with Engine in Chassis

[VT_4G63]

I wanted to get opinions on whether it was possible to swap out intake manifolds with the engine still in the bay.

I am looking to swap out the 2G intake manifold on the 2G head in my Spyder GST for an EVO 3 intake manifold. However, I’m not looking to pull the motor on this car just yet and am wondering if I can do this with the engine still in chassis. The studs on the bottom of the intake runners are what are making me question the feasibility of this.

Please let me know any opinions, or if anyone has done/attempted this (I’m sure both). I’m trying to avoid starting the removal of the necessary components on the head if it’s just going to be a fruitless effort.

Thank you

It’s not exactly fun, in my opinion, simply due to where everything is located and the fact you can’t see down there, but it is very possible.

I did it on a 1g. Likely very doable on a 2g. Get some bandaids.

I can tell you it is easier to pull the driver side axle / halfshaft to have access from the underside to remove the factory parts from the underside of the intake manifold with the vehicle on jackstands. Heck, its been nearly 20 years since I first pulled my factory intake manifold and like 18 years since I changed to a sheet metal intake manifold. Everything is doable, just know what you are doing, research, have thin durable work gloves or like 9mil nitrile gloves, be patient, and have good flex head low profile gear wrenches.

Yeah you can do it, its easier to remove it than it is to install it.

Remove the battery, then intercooler piping and throttle body first, then remove the egr valve so you have more room. Remove the fuel rail and injectors and set them to the side. You should be able to lay on your chest on the intake manifold and hug the manifold to get the lower bolts.

There may be one or two that you need to get from the bottom side from under the car, its never a bad idea to start out with the car already on jack stands

I have long arms, never needed to remove any axle or anything, it was fairly straight foreward to remove, but getting the bolts to thread back in to install it is very tedious and frustrating
