1986 2.5L TBI Performance Help

[Budde]

Can anyone tell me what modifications they have made to the 2.5L engines to get more power?

OH MY where to start [img]modules/phpBB_14/images/smiles/icon_smile.gif[/img] I started with a K&N air tube kit, PowerAid throttle body spacer (for a 4.0) and a 4.0 throttle body (hence the 4.0 spacer) -- same spacer actually, at leat for 97-up--. I then put on a Ravin Z-33 series muffler (available at Midas) and a free flow cat. Then came the Borla header. Still wanted more, so I put in a .256 camshaft (from your local Chrys./Dodge dealer). If you are looking for more.... either regear your diff's or do a motor swap. There aren't many hi-po parts for this little 2.5 (sorry to say). [addsig]

	Throttle body spacer A throttle body spacer is designed to improve the quality of the airflow, allowing air that is more condensed and, thus, more oxygen laden, to enter the combustion chamber. The result of this is a more efficient burn, which serves to release more energy from the fuel, making more horsepower available.
