I have a 98 4Runner 2.7L 5spd. I just ordered some fuel injectors from LCE Performance. I have a down injector and figured that for what these cost compared to a non Toyota reman I may as well go with these. I am now looking at purchasing this EFI kit minus the injectors. I would also like to purchase a K&N Cold Air Intake to go with it. I already have a LCE Long Tube Header, High Flow Cat, and 2.5" JBA Exhaust. I am looking for opinions on this setup and if it is worth the money. Will the K&N Cold Air Intake work better with the exhaust and intake being upgrading? I know this setup will cost a lot of money and I am looking to see what everyone thinks. Worth it or not? Also my engine has 290,000 miles on it and I am sure the intake and throttle body desperately need to be cleaned and I think this would be a good alternative to cleaning. I am slowly building up the truck and do not plan to ever sell it. Once this engine goes I will be rebuilding it so any parts I purchase for it will continue to be used.

 

You really aren't going to notice a nominal increase in performance with the CAI but you will see a slight increase in response time as well as well as mid - high range torque. I run the LCE Pro-Air intake on my 86' 2.4l along with the ceramic coated long tube header and a full flowmaster 2.5'' exhaust turned down over the rear axle. Compared to stock, yes, it is an improvement but if your looking for a serious increase in power and torque then I would consider re-gearing before throwing money at the 4 banger. My brother-in-law has a 96 tacoma with the 2.7l and that little rig gets great fuel economy and has plenty git up and go to it. I personnaly think the intake and exhaust combo is a great modification and it sounds way meaner but just don't expect seat of the pants performance from it and you will be satisfied.

 

Do you think there would be any fuel economy gains to be had from this setup? I am getting about 21mpg all the time right now even with a bad injector.
