Gtr Afm's

[gun-r32]

Im only looking at achieving between 300-320hp atw in my GTR. My question is, if I go Power FC for the ecu, will the stock GTR afm be adequate? Is it worth changing them to Z32 units? I'll be running between 1.0 and 1.3bar

definately not before the turbos...

i'm not good on these hp-kw calculations in my head but I do know that I am running 253kw without any problems, but they are getting pretty close to their max.

i say just try your set-up first with the stockies. you can see very quickly on the PFC if you need to upgrade or not.

so when do gtr afms max out? kw?

crap, sorry guys, should've listed my current mods.

R34 N1's, SS Ported dumps, Full SS 3" system from turbos back, Blitz Dual SBC running 1 bar.

why change to N1's if your only after 320rwhp?

Because he doesn't want ceramic dust through his engine .

Gunr32 you should be fine with stock afms , stock injectors will max out first .

[R31Nismoid]

to get a GTR upto 200rwkw you arent even putting danger or pressure on stock turbos.

thats a walk in the reliable park if iver ever seen it

you'd be better off using stock items with steel wheels and retaining the response IMO

anyhow, stock AFM/injectors... all will be fine.

Just a fuel pump possibly if yours is tired

Anyone know roughly what standard GTRs put out at the wheels? BNR32s for instance?

What do most stock 15 year old GTRs ramp up these days?

[R31Nismoid]

you can comfortably run 260-270rwkw (~350hp) reliably on stock turbos for good lengths of time.

Loads of Vic people doing it that havent upgraded turbos.

[ferni]

I've been running 260-270rwkw on my stock turbos/afms/inj for quite a while. I'd be aiming for closer to 400rwhp with those mods gunr32

[R31Nismoid]

450hp IMO
