My 3 door is currently on greens with a tt t34.55, 500 cooler, fresh rebuild but standard engine and head e.t.c. Still on l1 i believe with msd chip.

Thinking of changing spec slightly in winter. Just wondering which injectors are the next ones from greens which are readily available and how much cost wise?

Also would i benifit from an inlet cam at this stage? Bearing in mind ive standard pistons?

Lastly with a new spec of t34.55, injectors and possible cam what would i expect to see power wise? I understand they will be guestimates and i will select a tuner and discuss just wanting some ideas upfront. Thanks.
