According to Quafie, they recommend ATB differtials to accomdate Turbo base applications. In the near future, I will be planing to go turbo, but would like to use the Quafie system due to there reputation and reliability. However, cattmanperformance is selling the quafie diff for $1400. Now correct me if I'm wrong, the diff was around $1200. And Quafie America only distubute this product to Cattman Performance. What I see here is robbery!!

There is anothe diff system made by "Evolution-Autodesign". at
http://www.evolution-autodesign.com. I'm not sure on there reliablity. Do any of you guys recommend this product??? Will it hold up to Force-Induction??? Does it require additon parts to install?? Feedback would be great. Thanks.

 

Your link doesn't work for the evo-auto site. I spoke with Brian
about the pricing on the Quaife when I picked mine up (we work at the
same tech park here in Tucson). He basically had to front A LOT OF $
for the development of the part by Quaife. As a result, he needs to
recoup that dinero. Quaife had no interest in making it on their own
so someone had to step to the plate and he did.

If you think it's robbery now, wait until you get it and see how
small and insignificant it seems. You'll really feel robbed at that
point. BUT install it and go for a drive and you'll
feel like it's worth every penny. I personally think it's amazing
and I LOVE how my car launches and comes out of corners. It's not
robbery by any stretch. How can you beat a lifetime warranty that
specifically includes failure during off-road (e.g. track) use?

I'd make the decision to buy without hesitation.

This is Jeff at AP-Signworks. Evolution-Autodesign is a division of our shop. I was the one who got Vitek to build the LSD for the Maximas. I have one in my SC'd 4th gen auto and it's held up for 5 months now on the 3.33 pulley. The 5 spd. one has the same internals. A couple of .org members have bought the diff from us, but I don't know if they've installed them yet.

And you should see the diff in the Stillen catalog shortly, they got a couple of them for their catalog shoot. BTW, the diff is $750. The site lists it at $1000, but that includes the $250 refundable core charge. You don't need to order any other parts to install the diff, just the usual shims/seals. Same as you would when installing the Quaife.

And yeah, Brian Catts spent a tremendous amount of money to get the Quaife made, I spoke with him about this a while back. So $1400 isn't such a bad price. It's a low volume product for them. They sell their honda diffs for about $800, so it's all about volume.

 

Well, it comes with a lifetime warranty against defects and workmanship but I'm willing to bet it's voided if you race and maybe even if you boost. Further, it's a clutch type LSD, which is a significant variation from the Quaife. The Quaife is a gear based system. I'm not saying it's bad, just that it's not, as its price indicates, in the same league as the quaife. For this type of LSD you would probably be better off looking for a used I30t LSD in terms of price.

Cheers,

JK

 

OK. I see. Thats a bit re-assuring to see that there are options availiable. I will be very interested in aquiring this differential system from Evolution... The price is very good. Thanks for the info.

 

if your tripping about price get Eric Wongs quaife, hes selling it. Dont know for how much but you can get it for around $850 shipped. I just installed my quaife not long ago, I love this mod is awesome car handles differently trust me on this one. Look at the sig how to instructions are there.

 

Yeah. Under boost quaife covers all. So I may Have to spend the Money for it. My thoughts are going towards Quaife. Hopefully in the near future there maybe a good group deal posted. Thanks.

 

Nope, racing is covered, and so is boost.

2 different methods of accomplishing the same thing. Both have advantages and disadvantages.

If it makes it sound better, retail on the unit is $1200. I just sell it for much cheaper right now to get as many units on the market as possible.

 

I dont think youll get a quaife cheaper then a grand, maybe for now you may thats if not some swipped it from Ericwongs hand already.

Jeff I just sent you an email since you dont answer your pages on your cell phone

 

I will probably go with evolution system. Again thanks for the feedback. I will keep you in mind when I get the money togather. Roughly in 3 weeks.

 

You can't seriously be recommending that someone take a part from
Eric's transmission and put it in an otherwise perfectly fine tranny
can you?

 

I don't see a problem with doing that.












As long as he's not driving your car

 

the quaife is not broken, neither is the quaife I brought from someone who broke his tranny 3 times.

 

Well, if you think of it this way, that part is like the only one that survived. So if it can withstand his abuse, then it must be really, really strong.

 

He dont know other then that he would have never said that and I know his just joking

 

I was just joking too. I guess I should have put the there.

Seriously though, Eric's Quaife is being sold at a great price and someone should jump on it.
