I wanted todo header ,upipe, injectors, bigger intake, bigger turbo, fuel pump e85 tune... Would that be alright todo??? Any suggestions on brands anything???
As we've said, there are a lot of different ways to get to the same place. For 350 awhp you dont need to go too crazy.
header: you have the UEL vs EL debate...its kind of a toss-up, and probably not necessary for your goals. If you wanted to do one anyways, I'd suggest maybe the Grimmspeed ported OEM pieces. They're cost effective and give reasonable gains. For a money-no-object solution i'd recommend the KillerB EL solution. Its pricey, but quite nice.
UpPipe...lots of options here. I've heard some of the people i trust advise against ones with flex sections, citing failures.
Injectors is a biggie. Look at a previous discussion here (
link) for more info about brands. For size...you'll need to tell us if you wanna go e85 or stick to pump gas, but i imagine 850-1000cc should work for you.
Intake: not necessary. The stock intake is actually pretty good! Until you start getting to really large HP numbers, i'd throw a K&N filter in and call it a day (and save some money). If you are going to change it, i'd recommend the Cobb. Apparently it's got some tech in there to help smooth the airflow before the MAF that'll make things easier and smoother for you and your tuner
Bigger turbo: You dont need to go crazy here. You can probably get there on the stock turbo, but a small upgrade like the 20gxtr or 1.5xtr will definitely get you there.
Fuel Pump: Definitely! The stock one is pretty much at its limits at stage 2. There are lots of options here too. The industry standard is the Walbro, but its rather noisy. There are also Deatchwerks 200, 300 and 65c (depending on what year you have). Then there's aeromotive and a few others. I went with the DW200...its cheapish and should be good enough for what i plan to throw at it.
Intercooler: (you didnt mention this one) is not really necessary. If you do decide to upgrade stick with TMIC. You dont need the FMIC and a FMIC makes power later, reduces spool, etc... Personally i upgraded my GD intercooler for GR one. If you're already a GR there are some very nice ones you can get...but you really dont *need*.
EBCS: not really necessary per-se, but always a good upgrade. From what i've read most of the 3-ports are all the same, so pick one or find a good deal and go with that!
This goes without saying, but i'll say it anyways, make sure you get a tune with all your new goodies!
