after market gtr turbos (ecu opinions)

[87VLC26]

hey guys

got myself another 26 but out of a 33gtr, got 600cc injectors aftermarket fuel reg fuel rail, microtech lt12s,

the microtech lt12s was with the motor, havnt really seen to many people using them, are they any good?

just chasing some decent aftermarket turbos so can run bit more psi as my stock 32 urbos shat on first motor, looking for ones that sort of bolt straight on where stocks go as i have polished manifolds and custom dumps want to keep using,

model numbers brands be helpful, ?
or sugesstions ideas.

also got a spare rb26 motor 32gtr with turbos, injectors everything, 0 compression cylinder 6 and 3 is low looking to get rid of for 1k ono

cheers mick

gt 2860 rs is a common up grade or even some steel wheel n1 turbos, microtech is a good computer, Zacca at Cypher knows how to tune them

[Alt_F4]

Power aim?
2860 -5s (Not RS, that's SR20 fitment) fit the bill if your aiming towards 500hp, but otherwise look for 2860 -7 or -9s for for a responsive 4-450hp

Flog the microtech of to get some cash and run the stock 32 GTR with a nistune board... assuming your running the GTR loom?
Most places do installed + tuned + driveaway under $1K, much better solution than microcrap.

EDIT: for the same money as the twins, it might be worth while costing up a 6boost and a small/mid sized single

/medium/big single > twins

The dash series of garretts are probably the best value for A/M low mounts

[Kaido]

how much power do you want?
how much money do you want to spend?
when do you want full boost?

[87VLC26]

bout low 400s is reasonable for a car that doesnt handle, like 15_16psi, probably round 2k????

[87VLC26]

bout low 400s is reasonable for a car that doesnt handle, like mid range rpm its got 4:11s , probably round 2k????

HKS GT-SS (Or the garrett same)
full boost around 4500rpm 370rwhp @ 18psi with 600cc injectors close to maxing out 90%ish duty cycle

[87VLC26]

cheers man, scope them out for sure,

[BIGS]

Think Garrett version are cheaper than hks, -5 infamous mentioned sound like what your after. Think they are equivalent to gt2530 which is a next step up from gtss and will easy make your power with good response

Just to confirm whats already been clarified, the RS's are -10s and are FAR too laggy for street imo, you will need a built motor to handle those laggy bad boys, they are good for 450kw +

im running -7s im making 400hp @ 6800rpm at all 4 hubs on 1.2bar, 480nm is my max torque which isnt bad.

Only thing im missing now is some cams to stop the power from dropping off, could do 420-430 with cams id say and probably more boost but im happy with where its at now.

If i had the choice id go for -5's and run them at around 1.1-1.2 bar... then if you do go ahead with a rebuild you can wind the boost up and push over 500hp on the same items, but thats just me :)

yeah pretty much what he said but fuck that POS microtech off don't nis tune a gtr ecu coz you have to run afm's and afm's are fucking shit. Get a power fc dejetro, you will not look back. also look at getting a piping kit to remove the standard nissan cold side as it's rather restrictive.

also make sure you check up on your tuner before you use them.

[Brockas]

LISTEN TO THIS.

AFM's are terrible.

[_oz]

+1 to that :)

[Kaido]

what wrong with AFM?

afm cost vs dejetro cost
is about the same

[_oz]

Well Yes and No. If you can do the work yourself its cheaper but in my case it was much cheaper to go Dejetro.

The real advantage for me though is the fact that my car is ready for a single turbo conversion and i do not need to worry about piping for the afms, those twin greddy pipes are quite expensive, all i need is a simple 4" intake pipe and a pod filter.. easy

another thing is, AFMs can cause problems with top mounts with reversion of air going back to the AFM causing the engine to stall. pain in the ass !! some people are lucky with this, some people not so much.

Map sensors are so much easier and adaptable

The advantages of map sensors are maximised with custom turbo kits but if your running standard setup twins i guess afms are ok aswell but i have now joined the map sensor bandwagon and not jumping off :D

[BIGS]

Going high mount on my ex 200 meant sitting the afm immediately after the turbo inlet due to lack of room. Those who know will attest to this being impossible to run as reverbance is greatly increased. Solution was to hack the afm and stick the now exposed and sensitive sensor into the path of the Ic piping to measure airflow. This worked well for a short period until the sensor was ruined by muck.

Granted a gtr has more space to work with but why go afm when mafless nets more power, runs smoother, more reliable, allows further mod scope and looks neater.

Only plus for Nistune is stealth mode.

[87VLC26]

hell yeh love waking up to this, cheers boys, if the microtechs r so crap can u even sell em?? or they just crap for the rb's?

at this point looking like putting new turbos on first as easier while motor is out, get her running then source the apexi.

[BIGS]

Someone will snap it up I'm sure. I wouldn't go as far as calling it crap, just there's better choices. Speak to your preferred tuner about it.

[87VLC26]

tru, no problems.

cheers lads

[ONETEN]

another fan of the 2860-7 here, far better performing for street than the -10's and bigger due to almost factory spool times. Also, the microtech are a fairly average ECU devoid of features, no way i would use one on an RB26, the factory ecu is about 3 million times more advanced and is also 15 years older. Ebay should net you about 1k for it, which will pay for a nistune + fitting + tuning :D
