Gday all, I've been away for a while so how are ya all going, well I hope. I am finally back into the project and am looking for something to replace the stock ca18 engine mounts. I am asking this cause I am having trouble finding a set of engine mounts that are "cheap" and in good condition so I was looking at just swapping to something more readily available off the shelf at repco stuff.
I am using a Kev Rowley fitting kit and he designed his engine crossmember to use the factory CA engine mounts. I was thinkin of redrilling his crossmember to fit another type of mount but whats a close fitting mount??

Cheers
Anthony (bundy351)

im using Land Rover mounts under my CA (see my build) $40 apair new, or go Maddat's

r30 skyline mounts are good from a wrecker, may be different heights but i used them from the start when i did my conversion years ago

Make your own from polyurethane from auto one stores.
Use suspension high tensile bots and shock absorbers washers
from wreckers.

Will never tear or wear compared to all other rubberised mounts
and even internal sectioned poly designs. Just poly bushes compress
to take the strain, dead simple.

some pics for reference

that would be half way to solid mounting the motor though, in fact that would probably be more like 80% of the way to solid mounting

with the bolt passing entirely through the mount the mount will not work in tension only compression

imagine loading up the motor, say the right side is wanting to lift from the torque of the motor, the right hand mount will allow no movement, and the left hand mount would have very little movement under compression. the motor would hardly move. you would be transmitting a lot of vibration and stress through to your car chassis that would have been dampened by proper mounts

cheap yes, effective no

land rover mounts are a good cheap alternative, there is two lots on ebay, the cheaper ones are slightly taller (roughly 42mm vs 38mm from memory), though i bought these and they wont work in my application, the engine sump is sitting on the crossmember. I have bought some silvia ones to try as i think these are significantly taller than both - at least i hope they are. So you will need to check your mounts will suit the land rover height

kelpro has got some theres a part number for em on this site somewhere there cortina mounts or somethin there the same thickness there like 40 bucks and there's also a kelpro gearbox mount rubber too, pretty sure that part numbers on here too just use the search

i'm going to use the TD-TE cortina mounts to suit the 250 4.1L, i can get the part number if you like?

mesured my mounts for u today mik
silvia mount instald is about 63 mm face to face

The compression is all there, no less than rubber just a tad firmer, It is the most important part for stopping vibration and shock damage from bumps.
Torque chassis twist is rare unless massive torque is made.
Other vibrations havent been noticed in my friends rx4 with gen 3 v8.
Ive had solid mounted BP rotaries in my rx3 and r100 and loved the response.
Both BPs made 278-290hp at the engine and they shook like crazy when idling.

+1 for R30/R31 mounts. bolts are in the same spot as s13 but the mount is about 5-10mm shorter so the engine will be a little lower. they are also just a square rubber design so look alot neater than s13 ones
