Is this combo maxed?

[1owner]

Car runs consistent 116 mph in 1/4 with 20 #'s boost. I'm looking to raise hp enough to go 120 mph. Can I do this with upgrade to 50# injectors.
Here's the major components:
Stock block 61,000 miles, everything ported except exhaust manifolds, TE44, THDP, 2 1/2" exhaust, Blue Top's, ATR RP314A cam, Red's chips,stock size DOT tire.
What do you guys think?

Melissa ran 11.5s @118 with a stock motor but she ran 22#s also in street trim...hmmmmm you have your heads done....I would give the 50's a whirl...we ran 121 with heads an blues on another car BUT I dont recomend pushin blues that far..

I ran 121 on stock heads, stock cam, T63E, 50s.

Your turbo and injectors are "small" for ported heads, but probably work well on the street. As they say, it all depends on what you want.

Maybe you'd be a good customer for a new GT series turbo and some 50s or larger injectors.
