tryin to get 350 to 400. do i need a FPR or a wideband?

[harley1985]

im only looking for 350, but with the mods anda decent tune i can get more i think. i got a a/r 83 turbo. think thats a little over kill? things not going to spool till like 5 grand lol. hell idk im pretty new at all this to be honest. i just came across this turbo, its a borg warner s200 t3/t4 twin scroll. thats what i centering this build around. im getting a manual boost controller running about 14 psi. external WG. should be a lot of fun. picked up a header and EWG for 200 shipped, its a drift motion. picked up a apexi safc 2. got my 550's (evo with clips) ill just need the walboro with the 12v mod, the header (which i already got picked out) and the lexi. do i really need the fpr? also do i need the wideband? oh and of course in doing a felpro HG and a set of ARP's oh also i got the aluminum 1 piece, a 11 pound fidenza, hks BOV and a apexi intake. a rebuild will be in order, its got 140k but no leaks or problems. anyhow, anyone got some pointers for this newb? i do beleive in constructive criticism thanks.

Also you should pick up a Lexus AFM, AFPR, and Q45 Throttle body... Afm goes well with the 550's. You could get away without having to pickup an AFPR but why run the risk of not having enough fuel??? You will need a wideband (I got an Innovate Motorsports digital one for $166 on "the eBay")... Also for that big ass turbo you might want to look into a QSV (quick spool valve) I have no experience with them but hear they will allow you to hit the turbo power band much earlier... I am mid build right not as well... Also only looking for around 350

ya im gettin the lexi, wats with the q45 TB though? ive heard of the mod, but does it make a big differance? oh and ya i figured that if i put in the walboro then i may not need the frp. QSV? hhmmmm ill just wait and see what i get out of it when i get done with the build. im really new at turbos. dont know much about them. its kinda of the x factor in the build.

bigger throat = more air = more fuel = more GO!!!!!! I don't know a ton about turbo motors either.. i have an N/A now that is really strong and pulls hard but i want more so i bought a gte and am rebuilding it from the block up.

my first supra was a n/a i was always so jelous of the turbos. still miss my na though. ya i got how it works, just if its worth actually doing. checked on the s200, its going to be a perfect fit for wat im going for.
