i'm planning on putting a 13bt in a rx3 rolling chasis that i had bought. but, i have two different front mounts lying around. can someone help me out by ID-ing them so i can try to figure out which would be the best to use for my install? In the picture the far one has an RH stamped on it and the one in the front has a LH stamped on the back of it.

thanks!

 

without all the cars in front of me this is not a really easy task, not real hard either.

None of these mounts are for a R100 or Rx2, The smaller of the 2 mounts could be Rx3 or REPU ( I think Rx3 the repu mount ends should turn up more if i remember correctly), the larger of the 2 could be Rx4,Cosmo or early Rx7 ( i would bet on early rx7) with the smaller one being the Rx3.

However the easiest way to tell would be toss a couple of mounts on this and match it against the crossmember

 

got a chance to fit it in my rx3 today. the far one actually fits my mounts flush. the one in the front of the picture did not fit so well. the tabs where the mounts are about 10 degrees too high. also it seems like i just my be able to install i 60-1 turbo in the car with some banging using the HKS log type turbo manifold from my FC3S

 

the far one is rx3, the bigger one is rx4. Perhaps explains why the rx3 one fits better huh?
