My only question is, is this a RWD conversion or an AWD conversion?

Hi Jeremy,

I have an 05 GXP and want one of these within a week or two. Is this the stage 1 or 2 port job that is shown? I'd like a stage 2 if it is possible to get one fo a 05 GXP. Thanks in advance.

The item for sale is a "stage1".

Whoops, bad habit of rwhp/rwtq automatically came out when typing...yes it's wheel horse power.

Still available, thanks.

Can those terrible engine cover mounting prongs be removed?

Will there be a Stage 2?

They have done stage 2. I have one on my GXP and it is worth it, but needs to be tuned. It's running rich and bogs a bit at certain rpm levels .

Higsy,

Since you have a stage 2, can you explain the differences between the stage one and stage 2 port? Thanks dude...

Sure no probs. In picture 3 where the bottom of the intake is shown, there are three support posts which extend up through the middle .They are large 2 inch diameter embosses which look like they taper to about 3/4" dia, attaching to the top of the intake. You can see the interior view by looking inside the throttlebody opening and one of the posts is in view on the left side of the opening.
In a stage 2 port, these posts are entirely removed. It creates a hole in the bottom, which is then covered with approx. a 3" square piece of plastic which is screwed and sealed to it.
I also believe the porting in the runners and tb opening is more aggressive as well.
