Hi everyone I recently built my r32 rb25de and was putting on the transmission and cant seem to get it on all the way.  I'm using an action clutch kit and flywheel.  I had the alignment tool in when installing as well.  I put the trans on and it feels like its in also when I spin the crank it does spin the trans so I'm not too sure what to do.  Going to try and take off the PP and reinstall it.  Maybe the clutch isn't aligned right.  Any suggestions help.  Also its a normal single disk clutch.

Some clutch alignment tools are better than others

Start to tighten down the plate until it just holds, then wobble the alignment tool to center the plate, clutch and flywheel, then tighten it up to spec

If you just put the alignment tool in and tighten it up they sometimes don't align correctly because the plate is hanging a little low creating an angle

I had issue with this also the other day when I was attaching the gearbox to the motor. What did the trick was a bit of grease (not much) on the tip of the input shaft so it goes in nice into the pilot bushing, after the tranny was slightly in and making contact with the clutch plate (confirmed by rotating everything), I took a big block of wood, positioned it at the tail end and started whacking it with a big hammer. Surely enough, it started going in. Then I threaded in the 4 long bolts just a bit and kept hitting it and threading the bolts until the trans went flush with the dowel pins. Of course had to make sure the gearbox was aligned good when hitting it from the back, it was 2 of us doing it.

      Fuel Filter replacement

      By GTSBoy · Posted

      What's wrong with the OEM filter. They do the job perfectly. As to your actual problems. Stop driving the. Take it to a mechanic. If you actually do have a fuel delivery limitation and you are putting it under load, you could be killing it.

      ER34 AT ECU and HKS SLD pins

      I don't know the answer, but my uneducated guess is this will not work (or, not as you want it to). I would wire the SLD into VSS1, I bet that is what the limiter uses However, I also bet the ECU compares VSS1 and VSS2 and throws and error if they are different. Best suggestion I can make is wire it into VSS1 and see how you go, I guess the error will only appear above 180 when then SLD is active. If it appears at lower speeds put a switch into the SLD earth (or power supply) and only turn it on when you need to go over 180.

      Fuel Filter replacement

      By Diomedes_ · Posted

      Hi all, So, looking to do some general maintenance on the car, as it has developed a some slight (related?) problems; Three problems that I think are related. 1999 R34 GTR RB26 - engine will sometimes cut out while left on idle, but will keep going if I keep throttle input. Usually after having driven a while. Its random, somedays wont happen at all, others will happen once or twice in a half hour drive. - Second issue is that while driving, the car will sometimes not be able to get past 3k rpm, no matter how much throttle input I apply. - Lastly, car will sometimes be real laggy climbing through rpm, but if I apply lots of throttle problem will seem to clear and go back to normal. All issues come and go, again somedays no sign of any problem, other days will just be stuttering around for ages.   I think it might be either the fuel system, or maybe the AFM?   Either way, I am going to clean the AFMs, and replace the fuel filter, use some injector cleaner in the next few fill ups, and might look at doing the fuel pump aswell.   Question I have, is filter such as; https://www.efisolutions.com.au/pro-fuel-filter-30-micron-an8-orb-black Fine to replace the normal filter? Their product page says as a prefilter only and not as the main EFI filter, so I'm guessing I would still need the stock one? Can I get an aftermarket one that has AN8 fittings to replace the OEM one? Or is the OEM one just something you have to live with?

      I say this and there’s a Nistune r34 GTT MT ECU for sale on eBay.de but I need to figure out compatibility between the AT harness and MT ECU - TCS considered. I figure this HKS SLD is a quick bandaid anyhow.
