I was checking out the stats of the 2.7L SE to the 2.7L ES versions of the performance data and was wondering if it is possible to get the SE's engine tuned to perform like the 2.7L in the ES version. I understand that they are exactly the same engines, just tuned differently. How would I go about doing this? ( New PCM? )

I personally like the looks of the lower end torque on the 2.7L ES.

Interesting to note that Chrylser's latest concept...the "Crossfire" uses a built 2.7 that makes 275 hp. It does 0-60 in less then 6 seconds. Must be potential somewhere in there.

Carpoint is blowing smoke, (or inhaling it) There are just the 3 engines for Intrepids
the 200hp 2.7L, 222hp 3.2L, and 242hp 3.5L

So there is not 2 versions of the 2.7.

The ES's 2.7L engine does in fact put out more horsepower than the SE's 2.7L. But the ES is 201hp, not 202... accoring to dodge. The reason is the AutoStick feature. It is able to squeeze out one more horse for the wheels. The engines are exactly the same, just a different transmission :)

The reason the ES 2.7 makes more is cause it has an active tuning manifold valve like the old 3.5 and the new 3.2 and 3.5. So yes there is two different versions of the 2.7 but only the intake is different. The SE 2.7 does [email protected],100 and 190ft*[email protected],500. Don't quote me on the SE rpm numbers I can't remember them right off my head. The ES 2.7 with active intake manifold does [email protected],900 and 193ft*[email protected],300. You can quote me on the ES numbers I know them for sure off the top of my head.
:rolleyes:

A different intake? I thought it was because of the autostick... like how you can always get more power out of a manual rather than an automatic. Is there a way to put active intake on a base model?

We must be talking 2001's then because the 2000 2.7 has 1 and only one setup for manifold. Besides,the differences are so small it would not be noticed.

Bart, the type of transmission has nothing to do with an engine's total horsepower - that is measured before the transmission. And the Autostick is just a different program for the shifter - it's still an automatic transmission.

In 2000, the ES 2.7 had 202 horsepower, while the other hasd 200. The ES also had more "blistering punch" in midrange torque. ;^) Gotta love those Madison Avenue types.

I stand corrected, there are 2 differnt intake manifold setups for the 2.7L. One is basic and the other had a Manifold Tuning Valve. Just changing the manifold would also require the connections for the MTV and would the pcm use it even if it was there.

hmm... if there's a big enough jump in mid-range torque, it might be worth it. Anyone know if it's possible to put onto a base model without changing the pcm?
