Will upgrade intake Manifold-intake require better injectors??
I will be doing headers as my next upgrade, but after that my idea was to do the FAST 102mm LSXr for my LS2 along with the Nick Williams 102mm Throttle Body, Halltech 102mm MAF and i just need to find which intake matches this 102mm size im going for.
I was wondering if you have that much air coming in will you need to upgrade the fuel injectors so you can still maintain a proper ATF ratio.
With my LS2 already having cat-back Corsa Xtreme and the Halltech Venom tuned to 357, im hoping between headers and the intake mods mentioned above i can crest that elusive 400 rwhp LS2 mark.
Id rather avoid a cam/heads right now if i can.
Anyone had any experience like this or thinking along the sames lines as me?

Similar to Carl (but not as strong lol)
I am running:
AR 1 3/4 catted headers
Vararam cai
Fast 102 intake (out of the box)
Ported LS2 TB
Stock MAF
Stock Injectors
Putting down 399.48 rwhp/403.42 rwtq

Looks like these should get me where i want to go. I think ill just save up and do the headers with these and do one big tune when im ready. These should be the last mods for a long time for me. LG SuperPros and now possibly with cats if you both are showing you run the high-flow cats, thats promising. 1 3/4 is supposed to be solid for a long time to come so I think ill run those instead of the 7/8s. I'm not pushing crazy power so probably not necessary yet.
When I'm ready for this ill be curious to see if they can port the FAST 102. May as well get all i can out of the mods I am planning on.
Suspension on the other hand will probably be another set of mods. The poly bushings for my Z51 bars seem like a cheap upgrade worth its weight.

Stock injectors fine for full boltons
You can install all the aforementioned boltons and you will not need to size up on injectors. I had 408 rwhp/412 rwtq and was no where near needing injectors. Even with a small cam at 461 RWHP did not need injectors. I may need them this time after adding TF HEADS and anticipating a larger Cam and a 100MM MAF will then go to 46# Fast injectors.
