Anyone who has done the DET conversion can tell me weather its best to go with the s13 mounts on the DET? The reason I ask is that I cant get a spanner in the hole on the front sub frame to undo the S12 mounts. I know the
S12 mounts will bolt to the det block but with only 2 bolts were the s13 mounts have three.

The S13 mounts can just bolt up. It's a bit of a tight squeeze I found with Nismo mounts, as I think the s13 subframe is prob 1cm wider where they bolt in

I want to use the S13 mounts but I cant get the s12 ones unbolted. I cant get a spanner in the gap to unbolt them. I aint dropping the subframe.

Ah shit, yeah you need a bit of a bent spanner.

I will try and bend a spanner tomorrow with a *ucken big hammer

Do you think the s12 mounts will be ok ? after all they are only 2 bolt v 3 bolt

Well it depends, if you're a lunatic trying, drifting, dumping the clutch etc then a weakness in those bolts will show up.

In my old S12 I had the bolts shear on the inlet side. The engine dropped a few inches. It didn't drop any further because the oil filter stuff itself in to the side of the amount. Made a hole in the oil filter though.
