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

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.

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.

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

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

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

    • Yeah its bad eh. Ey! Watch your mouth. Yep, spot on. The rear's are always gone too though from brake checking. I had them perilously close to a tree that we had taken down. I think the tree peeps may have taken it. Either for a trophy, or accidentally.  
    • f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.
    • Oh and I lost my headlight washer jet cover!
    • Ok, so I got myself some X1 wheels really cheap to try out, they're a bit different and I like them but they're really narrow (18x8) they are available in staggered 18x8/9 also but really hard to find.  I kinda dig them, but not as much as the F10 19's I usually run, so these go into the wheel pile.         As I mentioned in another thread, I got a new exhaust. It's an off-the-shelf stainless one that fits OH-KAY. I don't love the tips size and how far they come out the back, I think I might cut the tips off and replace with some smaller (~3") ones that don't extend as far. It sounds really good though, I'm not sure if its just in my head but the car feels a little quicker, more responsive.      I fitted an eBay special front lip. Surprisingly it fit perfectly and all holes lined up. Its a little rickety but I haven't put any double sided tape on yet, I want to clean the front bar up where it has scraped the road a lot and fil in the number plate holes (or, get body coloured wrap to cover them - is this a thing?  I'm not sure if I'll leave it gloss or pain it matte. I really like it though, I don't particularly like the front bar without it, I don't really like the M-Sport and to get anything else is just too expensive. That said, I might need a new one now anyway as I dropped the car onto the jack after forgetting to put ramps under the front wheels. It bent a lot and while it did go back to normal after I got the car off the jack, I do fear I have not done it any favours.    Lastly, my headlights died. Different problems in each. They have gotten much dimmer over the past year or so, I put new (uber expensive) OSRAM bulbs in them but to no avail. One of them pointed at the ground and the other just kinda did its own thing with light working sometimes. Yeah, check this 18 year old BMW headlight wire. I reckon I know why they were stuffed.            BTW, the yellow and black is the power to the Xenons. Yikes. I hunted around an researched my options here. I would have loved to just get a replacement harness but not a thing. My car has adaptive headlights, that is they rotate left and right with the steering wheel. Good condition used adaptive xenons were over $700 each, non adaptive were around $400 each, but I couldn't help but think that they're all around 18 years old now, surely they'd have the same problems. So I looked at newer LCI headlights but they were even more expensive and I couldn't confirm that they'd be plug and play with lots of people having lots of opinions so not worth the risk.  I ended up getting brand new Chinese headlights from MARS. They're very close to OEM with only the angel eyes being a bit different. I didnt want crazy turn signals or sharp DRL's or anything. Not my bag.  They're not adaptive, I thought thats a feature I wouldn't really miss. So I coded that out.  The lights are awesome, they look so nice and they take so many years off the car. The angel eyes look great and the headlight brightness is ridiculous. I was so used to the old ones, I didn't realise just how bad they were. The new ones use the OEM bulbs, Xenon ballast and leveller motor which I was happier with. The only issue with them is that the rear cover is held on by SEVEN screws. This will be a nightmare to get to and open when I need to change bulbs.   
    • Now that you mention it I can see those too. More subtle. The lighting and low resolution makes it hard to assess super well what's going on but what is visible is bad enough to pull the motor.
