Okay...my itr trans is boring (4.40 FD)... would I be crazy to just swap in a 4.928 final drive in there and calling it a day?
is it really that crazy to run at roughly 5600rpm at ~90mph? Sounds pretty flippin' nuts even for me.
Another option is tossing in a LS 5th in there to compensate a little, but it's just not that gangster. But then again it should yield a hair higher in rpm at the same speed with the itr 5th w/the 4.40.
Also... the 4th gear makes me weary... should I swap it out? 100mph at 8400rpm doesn't shound too pleasing to me. Also, entertaining the idea of a longer first gear.
I have no idea wtf is good with this tranny bullshit... I are not understood transmissions.
If any of you have suggestions as far as what gears to use with a 4.928 final drive for peak performance, I am all ears. But mind you this is a daily driver, I'm just stupid.

98+ itr spec had 4.7xx you could prolly get that cheeper than the 4.9 then your accel will be good and have lower rpm but not buy much
-
lol, i actually have the same question. i was thinking of not going to crazy and just getting the 4.785 + LS 5th...
also love how you use 90mph, not 60 like everyone else... i always use 80mph when im talking engine/tranny speeds, cuz i dont do 60 :P

Just put a LS 5th into a CTR box, owner is very happy.
Don't forget about GearX FD's, I think I can get them for about $450.......

yeah I know... I just don't want the run of the mill itr tranny no more. I want something a little beefier than the 4.7 version. And I really don't wanna touch the motor, I wanna leave it realatively stock. So I figured I'd play with the tranny.

lol! 60mph has no significance to me... I cruise at 80-90 on the freeway, hahaha. I'm a realist not a fantasizer... lol!
I was contemplating the 4.7 for a brief moment, but I want something a little more aggressive, lol!

isn't the CTR just a 4.4 FD? the 4.4 isn't cutting it for me. It just makes it a B16 with LSD.
Oh and I'm going with MFactory LSD and FD... pro series FTW! 8)

Bone,
How much for cable l3 crx final drives?
-
The b16a gearing is already pretty ideal unless your running a tall tire at the track. Get more powa!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
alot of people around my way use the 4.40 b16 1/2 gsr3/4 ls 5 but that mostly boosted setups any all motor cars want there b16 trannys shits like gold here.
-
B series vtec stuff has been whored out for like 10+ years so it kinda is worth gold these days if its still in one piece
-
Coming from a 4.40, there is literally no difference between 4.7 and 4.9 FD. Wes calced it out, I think it was 1-1.5 mph difference per gear. Also, NA only you actually lose power with a turbo car unless you're trying to make up the difference with a taller tire in which case you need to worry about replacing more than a FD.
Do whatever is cheapest either 4.7 or 4.9, run an LS 5th. Should net a ~10% bump in power to the wheels in 1-4th.
