How do I identify a 1.6 vs 1.8 tranny?
I believe the PO may have put a 1.8 tranny in my '91. Since I am shopping for a new tranny identification of what I actually need would be helpful <G>. So, can I look under the car and identify what I have?
FWIW, I've gone from thinking I had a worn out 220K mile 1.6 tranny to thinking I screwed up a perfectly good 60K mile 1.8 tranny. |
I was under the impression that they were the same

The 1.8 tranny has a better synchro on 2nd, makes the 1-2 shift feel better. They are otherwise identical. They are exactly as strong/weak. Either clutch set up will work with either tranny.
I have a 1.8 flywheel and clutch between my original 1.6 engine and tranny. The only 1.8 tranny that won't directly swap to your 1.6 stuff is the 6 speed. IIRC it will bolt up to the motor fine, but is a bit longer than the 5 speed so you'd need to swap driveshafts too. There may be some other misc minor issues as well, don't remember the details, but the swap isn't bad. |
the tranny makes no difference on your clutch choice man if you wanted you could run a 6 speed on a bone stock 89 with original clutch. the Flywheel etc have to match the clutch but the bell housing is exsactly the same. As is the slave etc i believe.

Yeah you'd definitely be shifting more with the 6 speed. People get it for the pimp factor and the fact that it's stronger than the 5 speed. It would definitely be more work to drive, and not necessarily any quicker around the track due to extra shifting. I believe there are more ribs on the 6 speed case than on the 5 speed, makes the case stronger and less likely to flex.
The 6 speed with a 4.30 would surely suck balls, especially with a turbo. The 6 is likely to survive with 250-300 rwhp. A 5 speed may have to be replaced from time to time. But you can find the 5 speeds for $200, and the 6 speed will run $600-800 for the tranny plus upfront costs for the swap. |
you could pick up a stock 5 speed in good condition for 200 or less. and if yiou want more top end swap in a rx7 5th gear solo miata has the info on that. 3rd misses on me sometimes in cornering laod etc. no way around it we just need to learn to adapt and hope it isnt our cases flexing.
