Im just looking for some advice on upgrading auto trans. I'm driving a stock R33 SII (apart from the nifty nismo front ) I really dont know much about available options for automatics. What I would really like to fit would be a automatic trans with a sequential shift like the ones out on the new fords. I could always convert the car to manual but I feel that would be too much of a job.

yeah, don't belive anyone that says that auto's are shit, because they aren't.

DO what RNS11Z says, and then bomb your motor, and you'll have a nice little car that will change quick, and be good in straight line drags

Actually i believe its the other way round kamikazee. Your going to need a shift kit for the Auto. If you want 200+rwkw get it rebuilt with stronger internals, a new stall converter and bigger trans cooler

Do u know any where in brissy that does auto gtst gearbox mods?

actually the R34 tiptronic is the kind of thing im looking for. I dont want to buy a 34 because... err.. i just bought this 33 but yeah is it possible to get something like the R34 trans installed in a R33?? Otherwise im not complaining about autos at all. If I wanted a manual right up i would have bought one. (I do long drives as well as driving through the CBD and clutches frustrate me in traffic) It would be nice to have just a little more control over the gears when needed. I'm looking into shifts kits, is JATCO the thing to look for??

i cant find contact information for JATCO in japan but they have on their website a 5-SPEED Auto Transmission for Skylines. Unfortunately thats about all the info they give out. theres no links to a technical specs and not even an email address to ask them. who here knows about these transmissions and can they go in a R33 GTS?

your local auto workshop should be able to do some mods to the auto box aka stage 2 shift kit, which i believe helps in quicker changing of the auto box. as others have said, upgrade ecu, cooler, boost controller, air filter and you'll find the auto should be still fine

      I just looked at my camera phone settings, apparently I have "not allowed" for location  Will that stop that app?

      Can you not just turn it off on your phone if required? I remember a brief on this, well, I remember the brief, not what to actually do. LOL

      Thanks for posting, your engine bay looks tops. I'm fairly sure you posted the wrong video though, I think you were supposed to upload the one from your "private test road" where it's banging off the limiter with the gate open?

      Stagea obd II low voltage

      By MBS206 · Posted

      This is something to be careful of. I did a bit of digging on the NM35, as I spend a lot of time on near brand new cars and CANBus related stuff, which uses the same "OBD2" plug for a fair chunk of making my life easy. The NM35, does NOT support OBD2. The data pin is actually on Pin3, which is a manufacturer specific pin, and requires Consult3 to connect to the NM35. Your low voltage, is either because the NM35 doesn't have 12V to the constant power pin on the J1962 (OBD2) connector, OR, it is attempting the standard comms, (CanBus, K Line, etc) and can't see any voltage on those pins. Some people have had success accessing SOME data from the vehicle on OBD2 specification, using a module that supports KPW. My assumption, like Duncan has stated, it will likely actually be JOBD, where there is some cross over with the OBD2 and JOBD standards. Note, lots of "OBD2" dongles, do NOT support KPW, which is what you need for a lot of Japanese vehicles of this era (And even up until recent years!), EG, Subaru, Suzuki, etc.    The end of this thread is probably worth a read, as some people did find a way to get a display up in the NM35 recently, looks like someone implemented all the stuff needed to make it work. (The right protocols).
