Will I need to adjust fuel for this setup?

[984G634LIFE]

Do you guys think if I have a AGP L2R at 18lbs, stock IC, upper&lower IC pipes,Greddy type-s BOV, high flow cat ,greddy evo,K&N and Nitrous Xpress Ntercooler on a 2G I should change the injectors or get a safc? I'm not planning on doing anymore to my car for awhile so all i need is enough fuel for that setup. I run 94 octane also.

IMO, you would need a lot more than that. Even if your running low boost, I recommend getting a FMIC, fuel pump, injectors and some fuel control (s-afc...), port your exhaust manifold and get an o2 eliminator DP. Just check out the numerous tuning guides and youll see that none of them really recommend upgading turbo's unless you have the proper support for them. Which means fuel supply and exhaust flow

word!

I upgraded fuel pump, gauges, exhaust, S-AFC, logger, FMIC, Clutch.. then the injectors and turbo. It REALLY makes sense to upgrade everything before you install the turbo. Adding items one at a time will get you more comfortable with your setup and you will be able to see the results add up. IMHO this is the right way to mod, unless you have some serious cash.

18 psi on a L2R is not the same as 18psi on a T25. If you don't have any way to even tune the stock turbo and injectors, how in the hell are you going to manage an upgrade to a turbo the size of an L2R? Would you ever suggest to someone who has never ridden a motorcycle to buy a 1000 cc crotch rocket and tell them just give it gas? Sh!t no.

Here is a simple rule: It's never too early to do the supporting mods. There is a reason for that.

Well i do have a profec b and a safc and a pocket logger but theyre hooked up to my rs-t. I know how to make a fast car but i want my gst to run GOOD and be half ass fast. what about a t-28 upgrade and no ntercooler spray? would i need fuel mods besides the safc?

To get the full potential out of the T28 you'll have to get 550's and a 190lph fuel pump in addition to your AFC. Some may argue that the stock injectors and pump rewire can handle it, but I say go with this setup, it's tried and proven.

With a big 28 you don't have to have injectors or an afc. I ran mine for a little while before I got my injectors and afc. I ran 17psi and it worked fine. It was also alot faster than the strock turbo at the same boost so you could run 15psi and still be quick. You'll always have the extra boost on tap if you ever need it to. Only thing is I had evo o2, 3' exhaust, mbc, intake, uicp, feul pump, and bov.
