...now I know this is asked on an almost regular basis. And I know it has been covered many times. I myself started this same thread a year ago or so... And I've also spent the last half hour searching...

To the best of my knowledge, companies such as Quaife and Kaaz do not have applications for our car. So I will make my question very specific. Does anyone on here have a phantom grip installed?

I have heard it all before guys. I dont need to know about how the phantom grip is crap and will cause my diff gears to explode and rocket out of the car into the air causing a meteor shower of metal across the usa... i dont need to know about how i will have to rebuild my tranny in 20K miles either.

Ive heard all the bad things. Ive heard some good things... but never from someone with the phantom grip installed in a 7th gen. Does anyone have any first hand experience with these "lsds"?

you've heard all of the bad things and you still want it?

 
Rep Power: 0

not necessarily...

...im trying to gauge what is accurate from the info ive heard about phantom grip. that is why i am asking if anyone actually has experience with it. a mechanic of mine races SCCA ITA and has a phantom grip in his crx, and it has caused him no trouble as of yet.

it seems to me that a lot of people simply regurgitate what they read on other forums or in other threads, and state it as fact. "The phantom grip is crap, you will blow up your tranny! Return it at once!!"

i appreciate the heads up... but im searching for people with actual experience using the phantom grip to share their knowledge.

a 6th gen lsd will fit on our cars as well.

I don't have any expirence with 7th gens, but a car I have worked on does have a phantom grip installed, it is a 400hp neon, and it hasn't given him any problems yet. But we also haven't had it to the track yet either.

ive heard this. and also heard otherwise. until someone clarifies or tests this, i will continue to pursue a LSD specifically for a 7th gen.

thanks for the info! please let me know your future experiences with it.

edit:
riceburner has it, pm him maybe?

The reason people say the PG is crap is because it is like putting a bandaid on your differential - it puts a lot of stress on the spider gears of the differential (radially - outward on the sides of the gears). For the amount of money it costs to tear the transmission down, remove the differential, and install the PG - it just is a wiser investment to go with a complete LSD.

If you damage the PG, your whole differential is done (not to mention the gears and all other internals of the transmission).

I've contacted Quaife, and have researched this topic thouroughly - the last step is to purchase a quaife (or cheaper knockoff OBX replica, which can be had on ebay for about $500 vs Quaife's $1000). I just don't have the money or time to try right now....

i understand exactly how the phantom grip works. yes, it is like putting a bandaid on the diff. it is a cheap, probably not permanent, probably not ideal fix to having an open diff. the reason why i am so interested is bc i need to tear apart the tranny anyway to replace some synchros... so throwing an extra $300 on a phantom grip is not a big deal.

throwing a G on a quaife is more of a big deal. id be perfectly willing to do so... if i knew that it would work for sure. i am not going to be the guinea pig of a $1000 experiment.

i was also wondering about how phantom grips held up vs. how much power a car has. on the phantom grip website, the guys praising the product seem to be running low hp cars...

...if you imagine a high hp car with a phantom grip installed, the car technically does not have a true LSD. it basically has an open diff with slightly restricted differential action (from the phantom grip). so if the car still has an open diff, the tendency will be to unload the diff on the tire with the least traction upon exit of the corner (track example, bear with me drag guys). so a high hp car will have a much greater tendency towards stressing the spider gears in the diff, by unloading it. in a lower hp car, the same effect is true, but since there is much less power, there should be much less stress on the gears... and maybe this is why they hold up in low hp cars???

...a lower hp car would also benefit from NOT having the added weight of a quaife vs. a phantom grip.

...these are all just brainstorms/etc. trying to figure out a solution that best suits my application.

...i also pm-ed riceburner. so hopefully he can add some insight with his experience.

yeah but dont forget that in a lower hp car the parts are made to take less strain.

For the price - buy this:

Its cheap, yet should work fine. I want one, but as I said earlier, I can't afford it. Be the first one on 7th gen to have a REAL LSD in your car!

for the price that looks great!

...but you are sure the d17 and d16/15 use the same diff?

First of all, JamesL, I have to aplaud your knowledge. Secondly, I dont think that any major full LSD mfg. have aplications for our cars and I would like to know where this 6th gen diff fitting out 7th gen thing started. I just looked at the application list for quaife and they only list for b16 trannys. So if you all are correct and I have been in the dark for so long, you can take a b16/18 tranny and bolt it right up to our cars. Which comes to my next point. If you can take a B tranny, why not get a B16B (Civic Type-R) or B18C5 (Integra Type-R) tranny and bolt it up. They come from the factory with LSD's and you dont have to worry about taking apart the tranny. Makes ya think......

B series trannies don't bolt up to D16's, why would they bolt up to a D17?

 
Rep Power: 608

yeah, he has it...........supposedly it messed up his tranny.......but i don't know for sure.

Dude, shut up before you confuse people more....

Not 100%, but....

From a 2001:



From a 2000 D16 series:



They use the same bearings (80x40x18), same shim sizes, etc. I'm venturing that they will fit. As I stated earlier, I want to try one of the D16 LSDs in the D17 tranny. Its been proven before that the D17 tranny bolts up to the D16 (I believe Kezay or someone did it).

Give it a try, if it doesn't fit, just resell it on Honda-Tech - the OBX LSDs are hot stuff right now because they are $500 cheaper than a Quaife and do pretty much the same thing.

thanks for the visuals!

it looks like the gear pitch on the d16 diff is coarser than that of the d17...

i really am not interested in being a test subject... but ill see if any more information materializes.

If someone has a D17 Final drive I have a few Quaife diffs here I could try out.
