Hi

thanks for the info guys on the toyota engines it really helps , i have another question has anyone tried to modfy the throttle body and if you installe an electronic fuel pump does this help in power gain for a 4afe, efi 1993 engine .

if i take the head of the engine and cut a little bit of it to have more compresion i will have a gain in HP because i will have a shorter stroke right , but does this reflect the car tempresure do i have to install a new fan to maitain the notor cool
