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

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
