fulltime box in 3.7?


 Share

Recommended Posts

what are the options?

I know the XT6 is 3.9 and I woudl need turbo axles.

but is there a fulltime manual non-turbo non XT6 option.

 

I don't care about dual range...

but i'll take it...

this is from indy's site...

I am not sure which of these to look at.

also I knew the gearing was shorter on my DL the 2wd has a 3.9 instead of a 3.7

 

can anybody help me by pointing out which is fulltime.. and maybe telling me what car to look for?

after putting this here and reading it back...

I think what I am actually looking for is the single range 87.5 turbo box that isn't listed here...

sometimes after I post it just clicks in my head.

Full time 3.7's:

 

87+ Turbo Wagons

XT Turbo's with FT4WD (XT's have a some specific shifter linkages

87-89 (per GD below) RX's

newer like 2006ish WRX's some have 3.7 too!

 

EA 3.7's FT4WD MT's only came in turbo vehicles so they all have the turbo or XT6 spline shaft counts. if it's going into a car that currently has a non-turbo trans then you'll need to swap inner DOJ's or axles to match the new trans, but that's easy.

Fulltime didn't come out till '87. All the 85/86 RX's are part time transmissions with crappy low range.

 

87 to 89 RX (with diff lock and D/R)

88 and 89 FT4WD Turbo 5 speed's (diff lock but no D/R)

 

Sound to me like what you need is an EJ AWD tranny. Fulltime doesn't have a center VC. Has a diff lock instead.

That's interesting.

Also... Didn't realize the d/r fulltime didn't come out till 87.
