Need Help With Next Mods (ecu)

[bR33nt]

Hey all,

ok so heres what i got,

r33 s2 spec m

K+N pod, (in podbox and it gets cool air)

HDI FMIC

Kakimoto exhaust turbo back

Boost controller

Alloy radiator with gates hoses

brass button clutch

nismo 2way lsd

strenghtned gearbox

on 12psi it made 203rwkw on JAZMAC's dyno.

i just purchased a r34 turbo (op6) and its just been hi-flowed and rated at 270 -280rwkw with supporting mods,

im curious as to wat mods i might need for safety aswell as the power..

Im thinkin

ECU

Fuel pump - (bosch 044)

Injectors

Dyno - (final tune)

just wondering which injectors, ecu to go for, and have i missed any other parts out that i may need?..

cheers for the help.!

usual stuff you've listed.

AFM (depennding on ECU) - If PFC, Z32

ECU/Tune - PowerFC or ViPec seems the most common

Injectors - 550cc

Fuel pump - Bosch

Although don't get hung up on a power figure, more likely you'll make 260rwkw like most others

jazmac's dyno does read MUCH lower then most others in Adelaide. food for thought.

jazmac's dyno does read MUCH lower then most others in Adelaide. food for thought.

looking at the power figure of 203rwkw at 12psi std ecu i would say the opposite

[R31Nismoid]

^ yeah, i wasn't going to weight into that one... NFI how it can be much lower when infact its high.

[shyr33]

you might need coilpacks depending on the condition of your standard ones? Not sure what the standard ones are good for....

[R31Nismoid]

factory coils in good conditon will be fine for upto 350-400rwkw.

Infact the whole Nissan OEM system for RB26 & 26 is good for that (except R34's)

but sadly, 10-15 years, most are not in good condition.

Ahhh cheers for the info guys, Yeah i aint really fussed on the dyno figure at the end, just want it to be reliable and a gd safe tune.

We all no about the pfc, but vipec?? might have to look into these. (oh and my ecu has had wires cut on it but still has speed limiter etc) :S

yea mate i would go with:

-Power FC (D Jetro if you can to run MAP sensor and not dumb AFMs) or Haltech E11V2 if you are richie rich

-555cc or bigger injectors (remember that the bigger the injector the harder the idle quality is to control)

-Splitfires just to be sure...as mentioned std ones are cool but most in poo cond' and they have to deal with australian heat

- as for fuel pump i would go the bosch or a walbro

-not needed but for making the most out of your injectors get an adj' fuel reg (SARD my choice)

-dump pipe and high flow cat

-got the turbo sorted looks like but something like a GT-RS or many things from trust, HKS, Garrett etc but GT-RS has good response and is usable with std manifold

-as for tuners i went to a big name tuner in sydney because of the name and the fact they had the "worlds fastest WRX" and got a microtech fitted and tuned on my RB20...only to spend thousands and have it return with the ECU floating around under the passenger seat unbolted and driving like a cop and only 168kW atw at 18psi!!! took it to Mark at DAT Performance on the Central Coast and by playing with it for 20mins he got 182kW at 14psi!!! took it for a full tune and got 212kW @ 14psi...the previous workshop had the base map on it and near nothing else....now I take all my stuff to him including my RB25 swap.

Not that you live in sydney but just points out that you really have to pick carefully with tuners....someone who knows what they are doing but is also ethical.

Hope this helps

ahh cheers heaps jono,

yeah i got full zorst with no cat.

i heard somethin bout s15 injectors being suitable for this they are somethin like 480cc, any1 else heard anything about em,

yeah ill get some splitfires to be safe as ya said, its just hard tryin to find an ecu that wont brake bank, but might aswell just do it properly the first time i guess ey.

but as you said it really comes down to tuner alot aswell, i was gonna get jazmac to tune it and get it running, cause he does a good job and is fairly cheap, but if he cant or hes to busy ill just book it in with willal, we all no how good they are.. and nice bunch of blokes too.

[(OO)SKYLINE(OO)]

As mentioned, APexi Power FC...

I was also going to mention Adjustable Cam Gears and do a bit of head work...

[bR33nt]

alrighty cheers heaps everyone,

i no wat i want for christmas now? hahaah
