They don't go on the other way.

No, but it is possible to get the mounts upside down on the brackets (difficult with the locating dowel, but not impossible).

My advice is to double and triple check everything as it seems your 25 sits higher than my 30 does!

yup go figure hey....

have triple checked everything... not the first time i have done a conversion so not a complete noob.. really got no idea why teh hell it sits so high..

thinking elongating holes and 20 rubber mounts is looking to be the best option

Something I did to lower the 30 a bit was redrill the holes in the bracket that bolts to the block, drilled them 15mm lower but just figure out how much clearance you have from sump to cross member and lower accordingly.

That still doesn't explain why it is sitting too high though... I prefer to find the problem rather than dodge around it :D

nope nothing is on the wrong side....

find it kinda difficult to do something wrong with it dude....

my thoughts are as previously stated with 3 different types of engine mounts i may have one that sits differently..

when i was speaking to a few mechanics (well known workshops) before i did the conversion they told me that its not uncommon for them to sit high for some reason and it just seems to vary from one to the otehr.. he didnt understand it either.

as i said previously i have tried using both combinations ie all 20 bits and all 25 bits...

both sit high... the strut brace sits on the intake plenum and sits around 10mm or so above the strut tower..

There is not 3 different engine mounts. There is 20 and 25, that is all. There are three different gearbox mount types but they are all the same anyway.

You are either doing something wrong or your strut brace is not meant to fit. Take a photo

thinks i will be getting the camera out.. given that the strut brace fit with the 20 in it pretty sure its meant to be fitting :P

and as previously stated.. have run both all 20 mounts and brackets and subframe adn the same with the 25... and mounts WERE installed correctly.. honestly there isnt much you can "stuff" up hey. unless i have somehow managed to leave a 20mm metal plate on my cross member :)

will take some pics tonight

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
