R34 Gtr Stage 2 Upgrades

[Johnny]

Hi guys, for a while ive been planning the next stage of mods for my R, after reading the forums for peoples advice and experiences, I think i have an idea of what i want. Just after some clarification or criticisms so i can make a start on purchases.

oh, jst quick, my car is rarely driven and never has or will be taken to the track/drags; after anything over 300awkw with more low to mid range power/reduced lag

Intake: Will change from my apexi pods back to the stock airbox; i have an apexi panel filter and a nismo snorkel.

AFM: Would my stockers handle this power level or would a nismo upgrade be worthwhile?

Turbine: Seems that 2860-9 would be the go as they are off the shelf and bolt-on.

Water/Oil lines: Thinking of braided lines for the turbos as the solid OEM lines possibly can move and rupture (found this out on my s15)

Intercooler: Keeping the stocker but ill have it cleaned out of oils/deposits for the best efficiency

Dump Pipes: As ive read many times, the stockers will be fine; might have the internals grinded of jagged edges

Front Pipe: Have a stock pipe on ATM, worthwhile for an upgrade?

Injectors: Will stock provide enough flow - perhaps a fuel pressure regulator to boost the pressure?

Fuel Pump: Maybe a drop-in nismo upgrade - is this required?

Cam Gears: Not sure about which brand; maybe HKS, tomei etc

Ceramic Coating: Turbine exhaust housing; worthwhile?

My current mods produce 255awkw: have a power fc, HKS EVC, Fujisubo cat-back, high-flow cat and apexi pods. Creatd motorsports tuned the car and ive been very happy so ill stick with them.

I know this is a bit of a long thread and alot of information ive searched for previously but im just after a quick final review by anyone who cares to chime in - would be much appreciated

Thankyou in advance

PS: here she is now sporting some new nismo skirts and rear pods - im also grabbing a Z-tune bonnet (finally)

go the -9's

Use factory lines (best solution and bulletproof)

std dumps, make sure all heat sheilds are reused and no need to ceramic coat.

port match exh manifold to turbo mounting flange.

nismo afms (nicer resolution)

std pump

Upgrade Front pipe for sure

Injectors 555, 660 (std can be done for just over 300 but will be too close to max duty for my liking)

Cam Gears (see access autoworks)

killer setup 315-335kw easy (common outcome)

i bet it stands out at the bundy shops haha

[paulr33]

do you care about top speed?

download real car simulator, load up BNR34 stock specs with L tune and run on 1/4

then change the final ratio from 3.7 to 4.11 and see how it adjusts the car's acceleration

lmao!!!! only ever at the CBA ATM or nandos

Hmmm well not really, ill have to check that program out; maybe a change in final drive would be worth looking in2. I never go into 6th gear, except when im on a freeway.

Thanks for the tip

lolz wouldnt want to be able to say: i go from 0-150 in 6 seconds. Now at 9000rpm im out of gears

[paulr33]

it might be working look into, could be a cheap mod

i know snowman did it to his 34R to get more acceleration vs top speed

but not sure how it affects 5th @ 100km/h for example, it might make it rev too much and likewise may do the same for 6th gear @ 100km/h

Hmm might sound a bit daft but ill jump on my xbox later; forza motorspot 3 lmao!!!!!

hopefully snowman will post in his experience

He also changed the gearbox to the 5-speed so forget about that.

The R34 diff gears suit the getrag as the ratio's are different.

[paulr33]

well there u go, probably only useful with 5 speed vs std 6spd

[R31Nismoid]

If taking out the getrag you have to change the diff gears to R32/33 GTR (or GTS4) because the 3.45's in the R34 don't really gell at all well with the 5-speed.

[paulr33]

yeah make sense

i was under the impression snowman had the 6spd and changed to 4.11s with the 6spd for more acceleration

my bad

[N1GTR]

Do you have a link to this sim please?

[Marlin]

A 34R with the Getrag and 4:11 gears from a 32/33 is great, much much better. Yes, I know and and raced both

Highway cruise RPM is still totally fine and relaxed.

This mod = perfect.

[paulr33]

ill post it up tonight steve

dont have it online

[N1GTR]

Ok thanks heaps

[paulr33]

http://www.paulr33.com/downloads/simr.rar

unrar and run simr.exe

no need to install

load pit, BNR34 stock

then change the tune to L (low tune i think)

then do a stock 1/4 mile and see how you go

then change the diff gears as you like

you can even copy the gear ratios from BCNR33 (write them down on paper) and edit them into BNR34 ratios

result is BNR34 with 5 speed ratios

only problem is there is no dyno feature, so all you can do is 1/4 mile at flat knacker

[N1GTR]

Fkn legend.

Im so glad you stopped working on the house and got on SAU for a while
