Get the supercharger!!! Or do a 3.4 engine swap.

They're not easy to hop up. You can get a little performance and better sound with chips, exhausts and intakes, but to really go fast, you'll need to spend much cheese. If you're serious, consider the supercharger, which I'm quite sure will void any warranty.

Anything more than a catback muffler will void the factory warranty on the engine. I can't comment on aftermarket warranties, but I assume the same holds true there. If you are looking for serious hp gains the warranty is out of the question.

Are they doing superchargers for the 2.7L motor, or is the compression too high on the 2.7L?

TPC was making a 2.7 supercharger kit but they have discontinued them. Maybe if we could get enough people together they would do a run of them. Maybe a GROUP BUY???? The 2.5 kit is very similar but I understand that there are some issues with the way the pipes fit on the 2.5 vs the 2.7. Not sure about anyone else.

An extended warranty on a '97 is not such a great idea I think. Especially a limited "drive train" warranty. All the ones I have seen never seem to cover anything that actually breaks. I don't think that you will find anyone to write you a decent warranty on a 10 year old car. Call warranty Direct and see what they say. I would be interested to hear what they have to say.

Nope IA just not had enough people ask about the 2.7 to build a kit as of yet...

You may want to start a petition to have Stephen build one with an initial deposit from a few folks

Here is his email address.

What about the BI-TURBO?

Gamballa makes a Bi-Turbo or Twin turbo for our 2.7 L. It's not cheap but very powerful. I would still go with a Supercharger for a V6 car though. Turbos are great, but I think they work better on 4-Cyl engines. It's all about the compression ratios.

That Gemballa Bi-Turbo setup looks great but I've heard that Turbos generate a lot more heat than Super Chargers. I've heard that the Boxster engine is more prone to blowup from a Turbo than a S/C. I don't know if this is true or not. So I'd defintely want to do some research before going the turbo route.

Yes. Your right. That's why I said the S.C. would be better for our V6 cars. It's all about compresion ratios. Turbos seem to work better for 4-Cyl. engines. Like the Dodge SRT-4, VW GOLF, SUBARU IMPREZA, etc...they are all 4-Cyl.
