Bigger injectors?????

[323_mazdabator]

hey just wondering if any one can help, i'm just wondering if it is worth putting a set of bigger injectors in a BP motor? would it be worth doing? i was thinking a set of series 5 RX7 injectors. would i need i bigger fuel pump?

not while the engine is NA that's for sure. no reason too. for example, i will not change my injectors even if i get up above 110kw atw. mine are more than enough to handle it. all that you might want to do is get them flowed and cleaned properly (ie take them out of the car)

Money would be better spent preparing your car for more HP, bigger exhaust, cold air intake etc....

Have a plan and a workshop who is prepared to help you pull it off. Their are few single one off parts that will give power improvements, you need to think of the bigger picture.
If you put in a higher flow fuel pump now then you won't be lacking later on when your car is on the dyno starving of fuel. If your current fuel pump will cope with your planned HP then a bigger one would be a waste of money.

Getting realistic a stock fuel pump is good enough for a BPT with 11psi of boost.
The stock BPT injectors are good for 200hp ATW as proven by a couple of the
people on the board here choose your mods carefully and decide where you
want to end up so that you can buy the bits that can be updated now and save
what cant so that you only do it once.
