There are other “power” mods that are popular that if anything improve the feel of the car. The lightweight pulley is generally considered a useful mod. It reduces the drag of rotational weight on the crankshaft “releasing” about 3-5hp worth of energy to the wheels. The biggest benefit being better throttle response and faster revving.

Mr Josh sells a pulley for about $75.

Lightweight Flywheels provide the same type of gain as the pulley. It is generally recommended that you don’t do both the flywheel and the pulley as it may cause the car to idle poorly. Some owner report no problems but the recommendation is from knowledgeable sources.


GROUNDING KITS
Paranoid Fabrications sells a nice kit onfor between $35 and $50 depending on the level of wire and fabrication desired. He can be found on www.rs25.com .

THROTTLE BODY SPACER
While not a new concept in N/A performance enhancement, suppliers for this part for the EJ25 seem to be just one. Area1320 sells a EJ25 TB spacer and has dynos on their site showing around 4hp gain.
Noob questions:
I don't suppose anyone can post current contact info for any of these companies/guys?

Does it make a significant difference between a lightweight pulley and a lightweight pulley set?
