s5 n/a vert engine swaped into s5 coupe n/a help
 
1 Attachment(s)
hey guys i dropped in a s5 n/a vert engine in my 91 coupe but is there a difference in the engine brackets, i know that the s5 vert engine supports are a bit stiffer but they are the same size as the coupes stock engine supports
Im asking because i installed the s5 transmission and it seems like its a bit more forward, i took a quick pick since it started to rain, also i forgot to mention im also using the s5 n/a transmission from the vert

not sure what i have done wrong but the transmission should line up properly, i cant move it any further towards the rear

hey guys i got some better pics of my little problem, its hitting a bit on the shifter hole the only thing i know that i used differently is that im using vert engine supports instead of the original coupe supports, everything aligned properly, ive installed the driveshaft, the transmission support bolts are in place and the engine supports are in place, ive tried pulling on the back of the transmission hopping it will give me more room to fit it in place
could someone point me to the right direction, this is my first engine swap

+ 1 on the engine mount situation. And take pics of the Transmission cross member.

looks like it sitting to high, see if lowering makes it rotate backwards at the same time, then get them trans mount pix.

got some time to take some quick pics, i was unable to remove the engine supports, the vert transmission mounts are a different part number than the coupe, and are the vert engine mounts different than the coupe, also i loosen up the transmission mounts a bit and it lowers the transmission a bit and its not hitting anymore im guessing maybe the transmission mounts are incorrect but not sure

maybe that is a s4 trans mount.

The S5 vert uses a different engine sub-frame compared to the S5 coupe. You need to change engine mounts. Change from two FB67-39-040A (vert) to two FB01-39-040A (coupe). You also need to change the two transmission mounts from FB67-39-340B (vert) to two FB01-39-340A (coupe).

Also, your transmission x-member center busing is shot. You need to replace the x-member since this bushing isn't available from Mazda as a separate part.

thank you for the input, i replaced the crossmember with one i had on a backup transmission, also replaced the transmission mounts with FB01-39-040A (coupe) i had laying around in the garage , it did lower it a bit but it still hits a little, would it matter it i bent the shifter hole a little so it wont hit the engine compartment or would that be a bad idea?
does anyone know if the vert engine supports are taller than the ones coupes use
