Hey guys, I've recently manual swapped my RB25DE Skyline and have put a RB20E gearbox in. The RB20E gearbox is out of a series 1 R33 and my R33 is a series 2. Since doing the swap, I've noticed my speedo is reading just over double and the odometer is rolling the ks over faster. I have kept the original auto cluster in for now untill I can source a manual one. Could this be because of the transducer/speedo sensor? If so, which one would I need to get to get an accurate speed? An RB20E as this is what the gearbox is, or a RB25DE? Or could the issue be something else entirely? Cheers

Just putting this out there in case anyone is selling their R34/Stagea auto after a manual conversion: Looking to buy a fully built Tiptronic auto gearbox to suit an R34 GTT (RB25DET Neo, 1998 model): RE4R01B Tiptronic gearbox Must be built to handle at least 300 rwkw Stage 2 shift kit (MV Auto, KEAS or equivalent) 2nd gear billet servo New clutches/bands and solenoids High stall (optional) Trans cooler (optional) The box must be built by an auto specialist and come with a receipt with full specifications. Let me know how many kms on the box all up & since rebuild. Recent build preferred (2012/2013) and not really interested in anything from a write-off. Looking in VIC at this stage for easier inspection and pickup. PM me what you've got & where, reason for sale, and what you're after for it. Thanks!

I had a quick read of the conversion guide and seen that everyone was using GTR box keeping it AWD, I was wondering if u follow the same line, can u do the manual conversion with a RWD gearbox and by simply disconnecting the front driveshaft??? Any input would be greatly appreciated

Title says it all, anyone got one in good condition? Message me 0431143031 Pref located in Brisbane/Gold Coast/Sunny Coast/etc

As the title says, I am in urgent need of a series 1 automatic 4wd gearbox for my RS4 Stagea.

Y34 Cedric auto issues. Hey guys, sorry if this is in the wrong place etc. but I'm stuck, just bought a Nissan Cedric y34 with the vq30dd in it for my missus, drove from Sydney to wagga without a drama (5+ hours) , got near home at a set of traffic lights and as I took off it seemed as tho the transmission slipped into neutral, I rolled back because it wouldn't select any gears turned the car off, selected park and waited a few minutes. We then started it again it selected gears although after sitting there in park for a minute it slipped into 'neutral' again. It had to be towed to work and now I'm lost, checked fluids all seemed fine but it just continues to not select any gears. If anyone at all has any idea please help because I'm currently out of ideas !!! Thanks a lot, Paul.

R33/34 RB25DET gearbox Hey all, Looking to buy a good condtition R33/34 RB25DET Gearbox. Shifter/slave etc not essential but would be nice. It's for a mate who lives in remote QLD so buyer must be willing to ship. Thanks.

today i installed my engine (gearbox attached) and i thought i'll warn anyone attempting this to detach the tranny before installation it was a very tight fit probably due to the larger greddy plenum i had to drop the subframe 50-100mm for it to work

Hey guys ill do a write up as I go as there seems to be no info on how to drop the motor etc........ my problem is I have broken the crossover pipe from the drivers side exhaust header that leads to the turbo. I will write up a DIY guide as I go and take some photo's etc.

Hi Folks I'd really like a speedo, but the donor gearbox I put in was clearly cable driven in the past. I would love a second hand sensor if anyone has a gearbox kicking around gathering dust for some reason. These seem hard to find as understandably people rarely seperate them. But hey if thats you, please PM!

Hi, Wanting to buy a "C" type crossmember for my R32, currently re-shelling my GTST and the "B" type one doesnt fit, the holes need to be going the opposite direction! 0431 192 220 Cheers Damon

Chasing a stillway shifter for a r33 gts box. cash waiting.

Hi, I'm after a RB20 5 speed gearbox working or not working condition. I'm in Melbourne, Victoria. Let me know what you have. Thanks

Hi SAU, Looking to buy a healthy R34 GTR Getrag 6 gearbox. It's going into an R33 GTR, so if you have any of the conversion pieces (diffs, drive shafts, mounts, etc.) i'll also be interested in those. Please contact me here. Thanks, Josh

So I just finished installing my new clutch kit on my rs4 stagea, gear box is in and bolted up. The car comes with basically the same gearbox as a 33 gtr with a pull style clutch. I was just about to put the slave cylinder back on but realised that I could slide the clutch fork along the input shaft with no resistance. after getting some light I could tell that the throw out bearing isn’t locking in to the retaining clip on the pressure plate like its meant to. whenever I pull back on the fork it basically just pops right out with minimal force. I’m not sure if I’ve just damaged that little clip along the way somewhere or its defective. So is it possible to just buy a new clip from the manufacture?? Or maybe I’m just missing something is there a special way to get it to engage or something????? Pls help thanks

Speedtek Gearset Review This is a review based on my experience and may not correlate to your experience when dealing business with Speedtek Auto Racing Parts. TL,DR; Positives • Received the goods (gearset and rebuild kit) • Fair priced and holding up 540whp (soon to push more) • Conversations are in professional and respectable manner • Comfortable to resolve issues and will follow through • Many other higher HP cars in Europe using his products with success Negatives • He has been outside Australia from February 2017 till now, leaves his co-worker in Melbourne to run the business • Co-worker does not seem to conduct any QC prior to sending the goods out, defects were present in the product (read below) • Replies from him take days to weeks to get back in resolving issues (but was quick on the point of sale) being outside the country • Lead time was very average This is more suitable for somebody who has rebuild gearboxes before and understand the components inside, otherwise, it is just jibberish for you. I’ve placed an order for their replacement ‘strengthen’ gear set to replace the current OSGiken gear set on R33 GTR S3 gearbox along with new bearings, synchro and seals. The keyword was GTR Series 3 gearbox. Order was placed on mid-February 2017 and payment was done ever so promptly. Item was sent mid-March and received end of March. The person behind Speedtek is Alex Kantarovski, as some of you would know; he is in the no-good list in SAU with his previous dealings. I am in no way presenting him as a scammer in this review, I’ve received my goods and he is willing to help to resolve the issues I’ve found. He has been out of the country since the beginning of this year and leaves his machinist to produce the product and his co-worker as logistics support. Upon assembly and checking clearances, I realised that the input shaft (4th gear) cone diameter did not match with the synchro supplied. The 4th gear synchro supplied by Alex fitted the OSGiken input shaft properly but not with the input shaft supplied (S3 4th gear synchro is bigger in diameter and uses shifting keys instead of clips). The input shaft he supplied is suitable for R33 GTST GTR or Z32 with the smaller diameter 4th gear cone. I popped him a message early April and he replied by insisting that he will send the correct synchro promptly. The 4th gear synchro for his kit is basically an off the shelf synchro but re-machined to allow for the shifting keys instead of the clips. A month was lost and I received the replacement synchro early May. The day I received the replacement synchro, I received a message from Alex saying that there is an issue with the synchro that I just received. I checked it over the sliding hub and sure enough it has issue with the teeth indexing that will pose shifting problem. He insist that it is a one off issue from the machinist which has been rectified, another replacement will be sent to me soon. 4 days later, the replacement of the replacement is sent to me and received mid-May. Opening the parcel, the synchro has a defect. The machinist made a mistake in the CNC program and created an undercut on the face of the synchro like it smashed tool. Indexing appears to be ok and that undercut shouldn’t affect its function as it is in a non-critical zone. Alex apologised and insisted to send me another one; apparently his co-worker sent me a prototype. I received the replacement mid-May (so right now 4 x 4th gear synchro in total). So assembly starts right away, it is my mistake in just quickly checking the clearance on this synchro and close up the gearbox. I didn’t bother checking how the latest synchro indexes on the hub. With gearbox being back in the car, all gears engage smoothly….except 4th. It crunches whether you shift into it from neutral/standing still/driving/slow shift/fast shift. Double clutching fixes the issue. Contacted Alex about the problem, he suggested to check the diameter of the pilot bronze bush on the crank. He made his input shaft snout to be 16mm diameter. I pulled the gearbox off to confirm and surprisingly the pilot bush was stuck on the input shaft as I pull the gearbox off indicating the interference fit. Why he made it 16mm diameter? I don’t know. The stock and OSGiken input shaft snout measures 15.8mm diameter in which the bush is 16mm diameter internally. I was not informed of this change. I’m not going to call this as my oversight because there was no design advantage to make that change, hence, I didn’t check it. This was the most plausible explanation at the time to why it crunches 4th. I was then suggested to drill the bush out to 16.2mm diameter which I did and slapped the gearbox back on the car. Then still…..no Bueno. It still crunches 4th and the only thing I could think of is the indexing issue of the custom synchro he made, the groove cut for the shifting key was perhaps too narrow so that the synchro does not slightly provide positive engagement with the hub and inevitably the synchronising action pushing it onto the input shaft cone. After messages exchanged and with no luck with this 4th gear syncro, I suggested for a replacement input shaft. The replacement shaft will be to fit the 1st synchro he sent me which has a cone diameter identical to the S3 GTR and OSGiken, co-incidentally it is the same as R34 neo input shaft in which his machinist already has a program on the CNC. This was because I know that the 1st synchro he sent me is a correct off the shelf component rather than guessing with another custom syncro. This is where I am right now, another month has gone by and his co-worker is in the process of sending me the replacement input shaft. Further update to follow… Overall I am not entirely sure if there is anything special with the S3 GTR gearbox. I’ve rebuilt a couple of FS5R30A from R33 GTST, SR20 box and Honda B series gearboxes without an issue with off the shelf parts and this would hopefully be an one off unlucky event. Alex will assist you with any related issue, his parts looks good (not sure what material and heat treatment these gearsets are). He could improve with communication and getting information from his co-worker. I’ve read worse experience in SAU with other companies such as PAR where they seem to just throw you under the bus after sale.

Hey everyone, Had a look through the forums and can't seem to find an answer. Recent swapped my Rb25det + gear box into a new shell, got it all running fine but the gear box won't hold the uneven gears (1,3&5) I can't hold the shifter in the gear and it drives fine but as soon as I let go of the shifter it pops straight out. Anyone had a similar issue?
