Hi, Im from Spain and I´m going to install a Greddy on my stock 2zz. I need to know what´s the original pulley size. Some people say 3,4. Its that right?
It´s to hot on summer here and im not going water injection (tuner decission) so based on those factors I think 3,4 its the good way (maybe 7 psi)
Anyone with the stock pulley has a dyno?

Sorry for my english.
