Hi Steve,
You may already know about these other options, and I don't know if they'll get you 300 hp, but it's a start:
- TRD supercharger (most expensive aftermarket mod and may disqualify you from racing in some of the sanctioning bodies)
- TRD headers (expensive - or you can try slightly cheaper Edelbrock headers)
- Deckplate mod (I don't know if this cheap $10 mod will allow desert dust and sand through the intake, but many claim it provides a few extra hp)
- Amsoil or K&N air filter (again, I don't know if this will allow some desert dust and sand through the intake, but it supposedly flows more air than the stock paper filter)
You might want to check with Gadget at
www.gadgetonline.com</A> . This guy has experimented and dynoe'd a bunch of different mods on his 3.4L V6 4Runner and can probably help you. If you have an auto transmission, he can also help you with that too.
E.L. Prototypes supposedly offers some good engine performance parts for Toyota engines. You might want to check with them. They have a website, but unfortunately I don't know what it is.
You probably know this already, but another good source for 3.4L V6 info is at the Taco message board found at
www.tacomaterritory.com</A> .
Hope this helps. Take care,
Ed
