How To Install VMAX Ported TB on LFX Engine

One of the simplest mods you can do to this engine. Almost doesn't NEED the write-up, but some people like to see pictures before they buy.

Here's a comparison of the 2. Hard to see the changes, but you can really FEEL it with your finger. Stock is on the right.



Step 1, Unwrap the TB

Step 2, Remove the intake tube from the TB

Step 3, Disconnect the only connector going to your stock TB, and then remove the 4 10MM bolts holding it on. The connector can be a pain to remove if you have never done any like this before. You pull the red pin out and then you press your finger into the slot that is now open and pull.



Then just put the new TB in its place, and bolt back on.



Plug it back in, connect your intake tube, and you are good to go!

Nice job. I can see the the walls for the stock one is thicker.

Who did you order this from? And was the improvement noticeable?

I have a VMAX ported throttle body as well and I believe that it does make a difference on low end, off-idle acceleration. I feel like my car is just slightly more lively now that I have the ported throttle body. On the dyno, there's basically no gain to this mod (I showed a 3hp difference between last year's dyno day and this year's dyno day, but I would attribute a 3hp variance to weather more than the PTB), but you do feel it in the butt dyno.

I did the install at the same time as my CAI, I felt a minor improvement. I was truthfully expecting more low-end than I got. I like to keep the RPMs low when I drive around town, and I was hoping for a little more grunt after a turn in 3rd at like 18-20 mph, but it's still a little chuggy there.

However taking 1st up to 7000rpm is a nice sound and a nice feeling.

I ordered my intake + tb from ApexMotorsports. Got a good deal because of a debacle with the long delay of my rx catchcan.

On a side note, Please be careful and not over tighten the throttle body bolts. I sell a lot of the Vmax ported throttle bodies and a snug fit is good enough to the manifold.
