Looking for a 4.9 final drive 84-87 honda

looking for an 84-87 houseman final drive for a crx.

if you hear of one for sale anywhere please let me know.

[bonespec]

have you asked around on www.redpepperracing.com to see if they know any suppliers or someone who might have a used one?

[anrkii]

yep, ive been poking around there for one, still no luck
Supposedly theres only about a dozen of them in existance, making them pretty hard to find.

[iambhooper]

why dont you just get Housman to make you one? or, I'm sure if you were to get him to do a run, there are more than one or two people that might be interested.

[Greg Gauper]

Housman made a pair of custom 3.8 FD'd for myself & a fellow prod driver a year ago.

He can still make anything you want. Keep in mind they are not cheap! Somewhere in the $1200 - $1500 range each.

Probably easier to get made if you get together on a group buy.

Off topic...anybody have a 4.06 final drive laying around in a junk gearbox? I think they came on high altitude California cars but are very rare.

what is the benefit of the 4.9 over the 4.4? what is the comparisons between the phantiom limited slip and the others?

Will a MFactory D15/D16 4.9 final drive work? I don't know where the transmission break point is for a Civic/CRX past '88...

[bonespec]

nope, 88-91, then 92-00, 84-87 is a totally different case design.

88-00 use the same ring gear, but the 88-91 countershaft is about 3mm shorter.

I have a complete transmission with 4.9 Housemen REM'ed FD OPM LSD for sale. Sent PM.

[dazzlesa]

so who has been using the 4.9? has it helped? where has it helped?

[Ed Funk]

We have the 4.9 in both C cars, run the 225/45/13 Hoosiers. Pulls good everywhere, get to 6700 in 4th at LRP, use 5th at Pocono and Watkins, get about 6000 in 4th at NHMS, would expect to use 5th at Summit. With that gear and tire combo they do still pull in 5th!

[cfullgraf]

The 4.9 makes 5th gear useful.

With the 4.4 SI final drive, the gear box was primarily 4 speed box at Roebling, Road ATL, and CMP all with the 225/45/13 Hoosiers. I shifted into 5th because it was there but I never really was bumping at the red line.

That is not to say that the gearing with the 4.9 is perfect. Different tire sizes might be useful at some places.

One top ITC driver in the SE likes the 4.4 at Barber.

I have two gear boxes. one with the 4.9 and one with the 4.4 just in case.

[Greg Gauper]

Assuming 21" tall tires (don't recall what most people are running now)

The 4.93 gives you a top end of 77, 100, and 120 @ 6700 in 3rd, 4th, and 5th gears.
The stock 4.4 gives you a top end of 81, 112, and 134, which you'll never see..but this drops the revs for 120 in 5th to 6000.
