Rb26 To4Z Setup

[jun 2.7]

Hi guys i have a to4z setup with a power fc and z32 afm's has anyone run this setup or can anyone recommend if a to4z is to big to run Z32 afm's with a normal power fc due to the size of the turbo?

cheers guys

I ran a t04Z with stock afms so u will be fine

I much prefer the D-jetro option, speak to your tuner though they should have a preference...

Did you get any problems with the Afm's voltage spiking to much under light on/off throttle causing the car to stutter or hesitate and sometimes cause it to stall?

Haha this makes everything alright.

Cheers matey im seriously considering going this route and being done with it but my tuner has said that the car will be alot smoother and nicer to drive with normal power fc and afm's as opposed to d-jetro and a map sensor.. How do you find the d-jetro when your holding a certain speed on freeway and when your on off the throttle in traffic etc?

1 x z32 afm = 370kw at the flywheel of measurable airflow. (Or so i'm told). Are you running one or two?

That sounds like your tuner doesnt know how to tune d-jetro properly, so if you stay with that tuner, use afms.

Im running two z32's Afm's

this only occurs if the AFM are too close to the inlet, and reverberation etc.

if its spaced as far as possible, these issues seem not to occur

Ok now things are starting to make alot of sense thanks heaps matey.. And by the way excellent work on your Gts-R ive always had a soft spot for these

any tuner with experience will tell u the d jetro is a drag computer only. costs less to tune an apexi with afm's, and is smoother on the street.

Maybe they will tell you that... on planet retard

"experience" being no skills in tuning a map sensored ecu?

[DVS JEZ]

Its all the same when tuning. Map sensors just require some fiddling with transient throttle for nice throttle response

[paulr33]

agree, djetro and ljetro (ref DVS32R)

both are the same to tune and setup, and i think from memory the djetro takes longer as you have to work so much harder at the transient throttle process more to get it nice, vs AFM that is bulletproof on the factory maps on the powerfc, ie you dont have to focus so much on that area (from no throttle, to light throttle)

both will make same power and response

but will perform differently as far as mapping and scaling are concerned

but back on topic,

you should not max twin Z32s with T04Z

This is the log from my 460awkw dyno run. 26psi 2530's

The Z32's have some voltage left but the 800cc injectors are out...

Woww crazy stuff thanks heaps for all the advice guys much appreciated.

Jebuz! Is that on 98? Do the HKS turbos make more power than the -5s? I thought 400awkw was the limit of 2530/-5s on pump.

[R31Nismoid]

2530's are a bit bigger than -5s.
