B&G Performance in Detroit....only option for PCM reprogramming.

Here's what you can do....
-Bored out TB
-Intake Spacer (get with SPAD3)
-True Dual Exhaust
-High Stall Torque Converter
-Check with Intertia Motorsports to see if they have cams for the 2.7

Most of these mods I have done to my 3.5....
A 2.7 should be at least as receptive to these mods as a 3.5, if not more so due to the DOHC setup. However, you must (and I can't stress this enough) MUST maintain the 2.7 to a much higher degree than the 3.2 or the 3.5

In the end, going to a 3.5 HO might be the best solution.

Josh's spacer works on the 2.7?

This is true, but I think if someone went down the path with a 2.7, I think the results would be surprising.

Judging by what you've listed:

2.7L 74000 mile,K&N (square),Air Intake Maximizer,Voltage Power Module "RAIZIN",IAT chip "MIND BLOWER",AIRAID PCV filter,NGK Irridium IX

I think you've maxi-riced out the 2.7L already!

Wonder if you could bore one out. would be sweet to get it up in the low 3.x displacement, and the stock PCM would probably still be able to manage the fuel. DOHC FTW!

couple grand. You can keep your current transmission though, and you'll already have the SE top gear, so that's good.

not really, the filter itself represents the bulk of the improvement.

Hm.....If I know, round filter has a bigger sq. than my old K&N(installed into box),and hose FIPk make air way is smoother.

I'll never forget the article title in a car magazine that I saw about 15 years ago taking off on that cliché: "There's No Replacement For Displacement...Except Supercharging".

What fuel does the 2.7 call for? I'd think that premium fuel would be a waste, unless you've got a pre-detonation problem (unlikely).
