Advice for Helical LSD trans: IMO definite read.

[CyborgGT]

Lol! Sorry sir, i had to post it as soon as i saw it. The only thing that stumped me was what to put as a title. I think i've figured what to put now, i dunno

I, however, am confused. Could you not upgrade the final drive with a different type of LSD, or does he mean just with this particular company's gear sets?

I'm wanting Carbonetic's ATS 1.5 way LSD (here), as well as their 4.643 final drive gear set (here).

Just the type of information I was looking for.

If you're gonna swap an Mfactory FD in there, you might as well stuff in an F22 5th gear as well. Just a thought.

This is exactly what I plan on doing to my car soon. Only issue I've read about is that the f22 5th gear needs to be machined down a little cause it's wider than the H gear.

Also, I see a lot of mention in this thread about the M2B4 Tranny. Be careful when buying aftermarket parts for these because a lot of them specify that they "Don't fit LSD equipped models."

Good thread!

^Right, I have always been under the impression that you CANNOT add an aft. mkt. FD gearset to an OEM LSD tranny. Yet Shaun Van Beers installed the MFactory FD into a Euro R gearbox AKA T2W4 which is OEM LSD. I am going to assume that the M2B4, T2W4, T2T4, etc... all use the identical LSD or maybe they don't, IDK.

But I am curious since that FD was added to an OEM LSD tranny. Also, MFactory uses a USDM Prelude VTEC as an example for ETE, yet, the M2F4 is non-LSD. How could their FD unit fit both an M2F4 and a T2W4? 2 diff. designs maybe? Sorta thinking out loud here, I'll have to contact MFactory to see if they're stuff'll fit an M2B4.

Well The guy who used it (Shaun Van Beers) did say at first it was for the T2W4 trans, but then he also stated that it can be used with other transmission that have Helical LSD. I don't Honestly don't know about the Viscous LSD...my guess is "that's a negative ghostrider"

And to GraniteCB7, yes all of them use the same lsd. The only H- series trans that didn't use the helical is the type-s preludes, that used the viscous lsd

I want that 4.6 final drive! That Prelude was a beast with that 5.2 final drive in the after video.

[CyborgGT]

Yeah, 4.6 looks to be the best compromise between acceleration and cruising RPM if you really want to upgrade the final drive. The 'after' video never gets old, that Prelude boogies. When I go to beef up my transmission, it'll be interesting to see if an Accord fifth gear will lower that 70mph RPM from 3900 for better mileage.

Watch this get moved to N/A, lol.
