Which Turbo Is Best For Auto R33?

[aquariuz6]

just wondering what turbo would be best on a auto r33 25t

i would like a turbo that kicks in the low rpm towards close to redline

because auto wont even let me rev it close to redline

it just changes gear on its own

any auto SAU's that has had experience with this problem?

i was more looking into a HKS 2530? kicks in at 35k rpm

The HKS 2530 is a great little turbo, you will have tonnes of midrange but find it will drop of after 6,000rpm, if you want a little more got for the 2535 or a hiflow

I have a 2535 on my Auto R33, its a great turbo, peaks around 6500 with

tons of midrange, only a few hundred RPM more lag than standard turbo, you can barely feel it

I have that same problem atm though, sometimes after a few runs, the auto gearbox just shifts earlier and earlier. I have no idea why. So I get a great first run but it just gets worse after.

[paulr33]

heat is likely to be the killer in your setup lukits

do you have bigger trans cooler fitted

have you had the autbox serviced recently ?

[lukits01]

yea I have a transcooler and valvebody upgrade

didnt solve anything, during the install changed the fluid, and filter

problem still there, Im trying to install oil temp gauge to keep tabs on the auto box temperature, but having problems finding fittings for it

I cant imagine what your new RB30DET is going to be like with the 2535,tow a road train.

Recommend a highflow, There are two types, GCG do one with a BB cartridge, retails for around $1650, The other is a new bush bearing cartridge, Retails for around $1350. You retain standard plumbing & ducting.

Have done this upgrade on a couple of customer cars and they retain similar boost threshhold but pull right through revrange. your auto issues probably warrant a full manual valve body. Do the turbo upgrade fist, and go from there.

By upgrading the turbo, won't you have to start looking into ECU upgrades?

[FATAZZ]

i have a r33 turbo on my auto 32gtst. + SAFC

no problem pulling to redline.

the problem was it wasnt changing quick enough before redline and therefore just hit the limiter.

this problem will be solved very soon as my g/box is being rebuilt much much stronger

[lukits01]

who is rebuilding your gearbox? Where are you getting it done?

[Panikin]

MV Autos. Blackwood S.A. 08 83700430 Are well known for their upgraded auto boxes talk to them.

Ive got a GCG turbo. Its not bad at all, really livens the car up.

Will map most of the lag out with a DFA and EBC tune + cams will basically make it about as laggy as stock on about 15psi. Will be sweet

[ebola]

Want boost earlier? I'll swap turbos with you.

rb20det unit will be spooling up in no time, and since you never get anywhere near redline, it wont* run out of puff.

*wont = might not.

Buy a GT35R and enjoy the benefits of shitloads of torque and great response

[aquariuz6]

at what rev does the gcg hi flowed turbo's kick in?

is there any site to help me on this?

i was more thinking on hi flowing but last thing i want is a laggy turbo that goes off for a bit then my car changes gear... no benefit at all

[RB30-POWER]

Good thing with an auto is you can get away with rather large turbos as you can use the correct size stall converter to mask the torque hole down low.

[aquariuz6]

just a question... which of these 3 will have higher rwkw

- hiflow gcg

- hks 2530

- gtss

anyone have any experiences with the usual mods

fmic, zorst, safc, etc

[R31Nismoid]

aquariuz6 - you have posted a number of threads in the past month.

In each one you are asking something totally different, or very similar questions

You need to set a goal and stick to it

Then read the RB25 Dyno Sticky and see what works for you.

If you then compare the turbos yourself, and plug that against the goal that you end up deciding on.

Im not trying to be rude or anything, but we cant really help you, if you cant decide and then stick to it.

As RB Power said, you have an auto, if you get the right convertor you wont loose bottom end as much

[paulr33]

gcg hiflow

[aquariuz6]

sorry forgot to mention to ask which turbo will hav the highest rwkw at about 5000rpm?
