I just bought my crossfire two weeks ago and I was wondering what are some of the best ways to modify the engine? And what does a person have to do to add Nitrous Oxide System just on a stock motor?

 

the search function is excellent...

start with:

ecu tune
CIA
throttle body
pullies

lots lots more...

In general I think the TVT250 and TVT265 kits from TVT-Design are a good start for mods on a NA Crossfire. But really, like Violenteer said - the search works great and in this forum you'll find nearly everything you'll need to know about this car.

 

yeah...i really want trying to be rude...it is just you have to do some research and really nut it all out in your own head.

how much do you want to spend. do you want to go to the nth degree...

 

Come check out my site GummyGrip.com!! It's currently still under construction if you don't see what you're looking for email me or you can contact me on aim " iknowuwantm3 " and let me know what parts your interested. We're having a 4th of July sale ... get B & G springs for $239.00. I'm also willing to price match so if you find a better price that what I'm offering let me know!

 

I understand you are under construction, but why send XF people to your site when our car is not even listed yet

 

I'm glad to see new vendors pop up, but stick with the reputable ones for now.

www.tvtdesign.com
www.needswings.com
www.eurocharged.com
www.letmotorsports.com

The owners of all the above mentioned companies are extremely knowledgable and are more then willing to help you with your upgrade decisions.

Depending on your location, you may be close enough to stop in and have a chat.

 

GummyGrip, from what I have seen of your posts you need to GettaGrip on grammar and spelling.
