Gearbox position

Gearbox position
Hi,
Got problem with my gearbox position. Shift **** is moved much to right side, almost touches tunnel on passenger side.
I assume, that whole drivetrain is a bit twisted to passenger side. If i remove engine, is it possible to put gearbox on correct position ? Is there some regulation of bar, which is connecting gearbox with diff ?

Thing is more complicated. There was a swap made to 1.8t. But lots of things were f**** up, and have to do it almost from the scratch.
Atm i'm looking at all things.
Gearbox rear side is moved a lot to passenger side, so whole drivetrain must be positioned badly. What's more , gearbox is moved max to front, so shift **** is at top right of shift hole, which is bad, also shaft is not fully in gearbox - due to it's movement to front.
I'm gonna take out the engine and position gearbox in proper position, but need to know if there are any chances to set it properly.As i have seen, gearbox is mounted only to frame, connected to diff ?

the chances of the swapped engine being mated to the original rx8 tranny are very very slim. if it is by chance, then as said, somethings broke bad. if not, then how did they mount the trans they used? and even what trans was used?

Its probably a transmission that was in a RHD car. I have a 5 speed and the shifter is only an inch from the e-brake while in 5th gear. I just bent the e-brake handle about a half inch to the right so I stopped scrapping my knuckle....

Look at post 15. I almost didn't notice it but it seems like the 6 speed shifter slants to the driver and the 5 speed shift angles towards the passenger. I never measured before and after so i'm not 100% sure.
If someone could measure the difference between the shift **** in 5th gear on a stock 6 speed we would know for sure. I know my 5th gear was about 1 inch away from the ebrake before I bent it away.

Never noticed that before. I have one of each in the garage.... maybe have to pull them out and have a look. The bell housings have a bit if a cant to them... maybe that's why I didn't notice the difference installed. I know the 5 speed doesnt sit with the bottom pan flat.... like the FD tranny

Well, that might be some trace. But anyway, i've a feeling that engine is not ideally inline with car, back is a little turned into passenger side. I'll check it when i got engine out of car, will see if there's any chance to position gearbox more precisely.

Look like this - is it positioned good or wrong? It is pushed much to front, but i will take it back, what's only bothers me is inline position - cause shaft might not handle long in this position.

Since this is a swapped car and we can throw all logic out as it relates to the rx8, the answer is quite simple. Since the engine/bell-housing are solidly mounted together, then whomever made the motor mounts for this swap didn't keep things level (driver side too high/passenger side too low). Taking a few measurements should be able to confirm this. Also, you should check how the transmission is attached to the rear end. Did they use the PPF, modify the PPF, or solidly mount something? There is a good chance this is not level either...

Gearbox is fitted with original mount, i mean this frame connected to diff.
Probably engine mounts are bad, just like u said, one side is to high, other to low, and gearbox is a bit twisted to right.

your pictures dont look like the gearbox from an 8. so the original mount for the trans was most likely not used or heavily modified for the donor transmission. like said, the trans is mounted to the engine firmly, start there and work your way back

Something else. The trans looks RX8-y but what bell housing is it using? That would also play into overall possitioning.
Which 1.8t engine is this mounted to? Miata engine? VW?
If it's a complete Miata drivetrain then obviously the PPF and driveshaft are too short.

after some careful googling, your right it really looks like an rx8 5speed. but what 1.8t mates to the rx8 bell housing? unless theres an adapter plate, which may or may not be fabbed crooked
