Hi all,

I have come across some information that will be an absolute Godsend for those out there with an AUTO r33, I have done this mod myself and can tell you it will definitely quicken up your shifts for $0.

O.K here goes, on the inside front, drivers side, of the engine bay, facing the engine fan are 4 plugs on a bracket.

The TAN coloured plug is the one you want.

Find the red wire on this plug and cut it.

You can put a switch on it if you want,I did, which will allow you to switch your shifts from hard to soft.

Although I am told, its not as fast shifting as the valve body upgrade, the difference is very noticeable, Going around a corner at under half throttle my r33 chirps when it hits second.

Give it a go, it works wonders.

Disclaimer:-Do at your own risk as I am not a mechanic, and don't have any degree I am simply passing on this awesome info (I got from a mechanic) to fellow skyliners, and am void of any responsibility if anything were to go wrong with your car. (It sux how much you got to cover yourself these days)

any got an engine bay pic and can put a circle around the plug so i know which one it is ...im intrested to know what it does...

and with harder shifts do you think it will cause any damage to the auto, as the shifts are a lot more harsh ??

The wire you are talking about is listed on the wiring diagram as one of the feedback for the Auto to tell the Ecu when it is shifting this would cause a similar problem to using aftermarket Ecu's. No feedback = harsh and erratic shifts as the ecu will not retard the power with out the Auto telling it to do it.

I will definately not be doing this crazy D.I.Y. you can make your own decisions.

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
