hi guys, havnt posted here in a long time but have 3 questions i want answered and you guys seem to know more about the 1fzfe engine than anyone i know so ill ask here.
1. will a throttle body spacer have anny effect on a 1fzfe engine from a 105 cruiser
2. is it recommended to block off the egr valve (my engine is nearing 300000km so if i can stop some of the carbon build up it would be good) and will it give me any gains in fuel and power
3. i have to have my valve stem seals replaced which im hoping to do this year and since the head is coming off im probably gona have it ported and polished but was thinking also a bigger exhaust cam, would just doing exhaust cam instead of intake or both give me any extra power or torque or have any effect at all, i would do the intake aswell but my car uses enough fuel as is so dont want to make it drink too much more haha.
any advice would be greatly appreciated thanks
