R34 Gtr With No Boost Pressure

[bradsm87]

No need to go bigger than U need. The bigger sards require drilling out the fuel rail holes. I'm sure U could get 420 at the wheels with nismo 600's and a fuel pressure reg easily. I'm pretty sure nismos have 4 squirters.

Like I said I'm looking for something thats going to cover me for the max power of the 2860-5's, will they do the job? I just don't want them to anywhere close to maxing out. As asked before what is everyone with sard 700's using? the single hole version???

nice mods

Nothing wrong with the single hole Sard (Denso) injectors as their spray pattern is really good. I use 700cc ones in my R33 GTR equipped with HKS GT-SS turbos. It makes 330kw at 1.3 bar boost, injectors are at around 65 - 70% duty cycle.

My R32 makes 560kw at wheels with the 1000cc single hole injectors at around 70% duty also. I was running 660cc injectors and made 450kw at wheels on 99%. So 600 - 700cc will definitely be fine for you.

I'm selling the 660cc ones at the moment for a good price and will fit your application well - no modifications.

z32 afms are not better then nismo ones, nismo ones basically have z32 internal, in a standard diameter pipe,

advantages with nismos , direct bolt on everything fits,

disadvantages with z32, needs new plugs and different piping, but be able to stretch exiting piping to fit

id rather get nismo afm as the will flow bout the same

80mm is def less restriction than 65mm.

They aren't just Z32 internals in a smaller housing because if that was the case, it'd max out way too early because the air has to travel faster through the smaller diameter. I reckon a Z32 sensor and circuit in a RB26 AFM housing would max out at about 180rwkw each.

Nismo's are def fine and if he said he had a standard airbox, that'd def be the go but because he has pods, it's cheaper and slightly less restriction than nismos and u get a set of brand new filters with the money saved.

well the nismo ones are good for 775ps, =570kws

z32 x2 are good for bout 586kw

where as stock are good for bout 450ps= 330kws

umm 16kw difference

i suggest you do abit of research as i have

[bradsm87]

Yeh that's how much until they max out. That PROVES that nismo have different internals to Z32 because Z32 internals in an RB26 housing would max out far less. I didn't say nismo afm's max out at 180rwkw each, i said if z32 internals were put in an RB26 housing, it'd max out at about 180. Read what i wrote again.

Both Nismo and Z32 AFM's can read very similar max flow but the nismos are more of a restriction as they are smaller. It's only marginal i know but if it's cheaper then every little it less restriction helps.

BK what brand are your injectors the 660cc ones that your selling??? Also what is the spray pattern, how many km's/how old are they and how much are you asking for???

20 questions or what LOL...

Full stick you have a PM
