wow looks like you having fun ! whats the mileage on the car? and why are you doing this? you like 5 speed better ? keep in mine you got a 3.90 diff in the rear since its a auto.

i would assume it has something to do with "fun factor". An auto US vert is THE slowest thing ever made with a rotary. That is probably not true, but it feels like it.

bigtony08 · 02-15-2009, 11:24 AM

no all verts have a 4.10 rear. and im doing the swap cause trannys dead and for the fun factor lol

actually that isnt correct.

1988 and 1989 verts had 3.91 final drives regardless of the transmission they were sold with. Then for 1990 the 4.10 became the final drive for the manual transmission (like the coupes) and a 3.91 was retained for the automatics.

damn that sucks sorry bout that. btw do i need to retain the tranny cooler lines or just pinch them off. and how hard is it usualy to get the TC bolts out im haveing a hell of a time. also how is that rear end is it still ok to run with the five speed. also Low the car has 91000 miles on it

Whizbang · 02-15-2009, 02:35 PM

the tranny cooler lines that feed to the radiator are fine left unconnected at the radiator. As far as the torque converter bolts, i use impacts on everything 90% of the time.

The rear is not THAT bad. My 88 vert only came in 5 spd (1988 thing for verts) and as previously stated, has the 3.91. It gets better fuel mileage at the loss of some performance. Biggest thing is the wieght of the vert compared to a coupe. But coming from an automatic to a manual is a pretty big leap, especially in the enjoyment department

bigtony08 · 02-15-2009, 02:43 PM

what about the vacume line running to it just plug it? and how can you get an impact in to thoes bolts. also can i pull the tranny with the torque converter still atached to the flex plate and then unbolt it

Rotary#10 · 02-15-2009, 02:48 PM

are you using the FSM ? be sure to get some vac hose nipple covers for those ends on to where ever they go. still looks good for 91,xxx miles

bigtony08 · 02-15-2009, 03:03 PM

thanks and what is FSM?

Do you have a transmission to go in this thing already? I would STRONGLY recomend you to use the Turbo transmission, along with a performance clutch, this might be a bit more expensive to do, but in the long run, the N/A transmissions are known to fail, even more so, the stock clutch disks are even worse!

NOTE: A nice thing about an auto to manual swap, is that you can retain the stock driveshaft if you get the Turbo model's transmission, it's a bit a bit of a ghetto fit, but this will allow you to retain the stock rear end untill you have more money to buy a turbo differential housing.

Further info on differentials: FD (1993-1995) models have a really nice TORSEN unit that fits into the FC turbo rear diff housing, this is a setup I am doing myself, and one that has been recomended numerous times by others who did it)

Anyway, good luck with the swap, is it just me, or does it looks like a lot of people have gotten blue S5 convertibles lately? (I have one too!)

bigtony08 · 02-16-2009, 11:35 AM

semes to be a common color. but yea i already have everything plus im not really gonna mod anthing but the suspension. and maybe like a half bridge
