Hey guys looking to start this project right so i need some help. Looking to get some HP for my sr20 with a new fuel pump and injectors. Now if i do this what will i need to do with the ecu? Do i need a Power FC? Also, what type of fuel pump and injectors should i get I'm fig. walbro 255 FP cause i guess thats what pop. and cheap. But, i have no clue on the injectors. Help!:aw:

ECU if you can find a a Power FC that will work find, APEXI has discontiued them for now cause they are redoing all there electronic lines but i am sure they still got some somewhere. The GReddy Emanage Ultimate is awesome and you can do just about anything you want and they make plug n play connectors for them. As Injectors how my HP you going with either way HKS injectors are great and not very expensive. Let me know if you have anymore questions

Walbro pump is pretty standard, make sure you buy from a legit source so you don't wind up with a chinese knockoff. Nismo (tomei) are popular injectors for the SR, they are drop in and require no modification, but any side feed high impedance injectors will do. If you change the injectors you will need to compensate with tuning. If you are still running the stock turbo the only thing you need is an upgraded fuel pump, the stock injectors are ok to ~250whp, 14psi on a T25. If you want to upgrade the turbo you also need to change the MAF to a Z32 or something appropriate for the increase in air, or go MAP depending on ecu. You really didn't specify much in your post as to what your plans are though.

Yeah now that i got a chance too do a little more research i'm sorry for the crap post. Right now i have a intake and 3in down pipe with a straight back exhaust. I'm looking to get to about 325 350 hp. Now with that research i've done which isn't much but i'm fig. injectors fuel pump with a safc 2? Also, for a FMIC i still have a stock front end with fog lights. Is there enough room the remove the lights and fit a FMIC or should i get a full body kit to have it fit better? Last, what about a exhaust manifold? o yeha and i'm already in search of a z32 MAFs thx Once again sorry for the crappy post new to all this. Please bare with me.

you dont need a full body kit to fit a front mount
you dont even need front aero to run fmic
have you searched even remotely for anything about anything at all?
