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

      High temp brake fluid?

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
