WetGTR

Found one now. Thanks guys for your offers.

I'm after a second hand GTR R33 gearbox or the internal gear sets.

Keep the factory BOV's. I still have them on my GTR and it running 600hp at the wheels and does a beautiful job.

anyne got a return spring from the inspection plate at the top of the gearbox - under the bolt that is bigger then the rest?

Just wondering, got your old gearbox?

Wanted to know if anyone has the return spring that goes into the reverse check from the rear extension of the gearbox. I can't find mine when I rebuilt my gearbox and wanted to know if anyone had a blown or broken gearbox that wouldn't mined selling me this small part. I have gone to Nissan to buy one but my heart stopped when they said the word "this part is unavailable"..... I went through all the pain of rebuilding my gearbox by myself after I blew 3rd gear and stopped by a small spring. I know it wouldn't matter if it was from an R32 GTR or R33 GTR but I wonder if its the same for GTS & GTT gearboxes. Any help would be greatly appreiated.

Yep, knew I was on borrowed time, but what can you do....... but what a rush!!!

Looking at buying a GTR R33 gearbox as my 3rd synro has blown.

I have a tricky question...... If only the compression was raised on an engine say 8.2:1 raised to 9:1, what would be the real world results? Has anyone just raised the compression and found that they have gone from using 16L/100km to 11L/100km? Keeping in mind that squish plays a part if compression was raised by just using a head gasket.

I have to agree, always tune for best drivablity and what ever WOT figure you get, thats fine as long as its useable. Looks like you got the O2 Sensor Autronics recommend. The LSM-11 is a 4-wire wide band as they call it which can be used as a narrow band sensor or a wide band sensor. It will only work wide band connected to an Autronics A/F Meter and when connected to a SM4 which will feed it the 5V and the tuner will use voltage scaling to make it work with close loop control. I have used both closed loop control and just the target A/F in the map. You would be suprisd at how good the targets are when they are tuned at the correct A/F. Only problem I have had is that the sensor would only read accurately to 15.5 A/F but could run leaner at certain load points when on cruise. If I disable closed loop and just dial it in at the rpm and load point the A/F I wish to run I could run leaner then when closed loop is enabled. I not suggesting anything here, just the Autronics is so very accurate and precise - what an awsome ECU. Is the tuner an Autronics dealer?

Yes, you can run closed loop on the SMC 1.92. The wide band o2 sensor you got, is it the Bosch item LSM-11? The SM4 will not accept a direct 5-wire wide band sensor, I have confirmed this with Autronics on their forum. It will do a 0-5V o2 sensor with voltage scaling for the A/F readouts. Still a better way then a narrow band 0-1V method The SM4 has a very flexiable close loop control so will work very well. What I would do about the plugs is let the tuner replace them but tell them you want them back. Give them a clean the way do did it before (best way I beleive) and stick them straight back in. I don't beileve that they are fouled beyond repair and even if they are, surely not all and even if they all are, well at least you have them back. Let me know how your fuel consumption goes as I am interested in the results. Good Luck with the tuning! Post the results

Sorry, I don't want to high jack the tread but I'm dying to ask! Wanted to know what everyone's fuel comsumption in from an RB26 with Autronics. My fuel consumption at this point around 16L/100km's with some city and highway driving, so around 340km per tank. I'm running an SMC 1.92 with 500R CDI Im using 800cc injectors with 260in 260ex cams, this is stated as injectors and cam duraction plays a part in fuel economy.

With regrads to large injectors using more fuel for economy, this is correct as atomisation is not as good as smaller injectors. The smaller injector atomise better, even more so at light loads. Injector manufactures have developed single,twin and four pittle injectors to help the spray pattern and atomise the fuel better. This also helps direct the spray towards the rear of both valves in a four valve per cylinder engine. I have tried this myself and have changed the same injector brand and size from a single pittle injector to a twin pittle version and the twin pittle version ran richer then the single pittle version. This has to do with the above comments mentioned.

Exactly what rob82 says. Go with the Aten USB to Serial. This item will work.
