Ok what if I wanted to fully convert my Evo Viii to JDM specs. WHat would I need.
AYC, ACD front limited slip differential.
What about the engine.
Is this a doable project. I am very interested. Are you?

 

Do I want more power? Yes. And that's while I'll be going with the AMS Stage I setup or even stage II. And be faster than a JDM evo, if that's your main point of comparison. www.automotosports.com

Front LSD? I'm certainly interested, but not really concerned. If my car was seeing a lot of track time, a front LSD would be critical. Anyways, there will be a few manufacturers offering this before long...

AYC / ACD? Not interested. No need for any form of traction control in my car.

what's included in the AMS stage 1 setup?

 

why...? it's not worth the headache...

you'd be better off importing a JDM version...

 

You shouldn't waste your money trying to convert you USDM evo into a JDM... too much money!!! You could just put that money into performance part and would be able to smoke a stock JDM evo!

 

I thought the JDM version was not street legal yet. Even the LHD on which is the Euro version I guess.
The purpose for this is to get faster track times. More power with a stage 1 will be a possibility but handling is a priority as well.

 

once you reach the limits of the stock US EVO than maybe it will be time to look at other options. so far i haven't heard a single person who complained about the us vs. JDM EVO. i have driven both a USDM EVO and a JDM EVO VII and i can tell you that you won't notice the differenece. if you still feel the need for more than your best bet would be to look at companys like cusco for better diffs that will still cost you less than the conversion you are talking about. i simply don't see why people feel the need to change something if it is not broken. another way is to simply add better sway bars and strut bars and maybe some links to reduce bosy roll even more and the entire deal will cost you less than 1G.

 

also,

for a better example of what i am talking about, take a look at the USDM STI (no bashing or flames, i do love the STI). when people heard that it will be coming with 3 diffs including dccd, everybody assumed that it will eat the EVO alive. almost every test out there showed that the EVO handles better and feel better at the limits even with less diffs. i for one love the way the EVO handles and don't see any reason to change it unless...
if you are at the track racing all the time and you feel that you have reached the limit and you feel that with another diff you can do much better, than you should add that diff.

 

Blonde thanks for your response. I agree with you. I guess I assumed that the JDM Evo had far superior handling with respect to the US Evo. That is why I was wondering. My Evo is completly stock . I took it to the track and I feel like it has a bit of turn in understeer. What do you suggest to fix this problem. I have the stock allignement. Could that change slight understeer?
Thanks for the response

 

camber adjustments would be a good start but i would also look into sway bars and strut bars. they will reduce body roll at the expense of a harsher ride so think good if you want the pay the price. i understand your problem and will all face it in some level or another. i only have two problems with this issue:

1) people are getting so worked up about gizmos these days that they actually don't realize what is the main point of cars. for example, if i had to pick 2 cars that i love to drive it will be the mazda miata and the old Z cars. both have almost no gizmos but are fun to drive.
2) there are many people out there that feel the need to change things that are fine as is simply so they can say they changed it. for example, VIVID RACING's car (as nice as it is). the guy took the BREMBOS which are amzing brakes (mind you that BOZZ 600hp EVO VI uses them) and changed them to a differenet brake kit. then he took out the RECARO'S which IMHO arethe nicest seats to ever come with a car and changed them to a differenet brand of racing seats. by looking at his car you would think that he drives at the TSUKUBA track every time when in real life the car goes from one show to the other.

my best advice to you is to talk to people who know what they are talking about. here is the list of people i would talk to if i were you:

1) Claudius - no need for intro, the guy knows his EVO
2) Paul Hanson- APEX Japan editor, tracks cars for a living.
3) Z1 Adam - a great tuner who worked on many EVOs.
4) WORKS

 

Pardon me. Either I'm way off base or blonde is on crack. Doesn't the US Evo also have 3 differentials (front, center, rear)?

 

the evo does come with 3 diffs but they are totally different than the STI diffs. it has a open front diff and a mechanical rear diff. sorry for the confusion.

 

my point was that even with out the acd and ayc, the EVO still is a great handler

 

Intake, Boost Controller, Super AFC-II, exhaust.

It's listed on their website: www.automotosports.com

Their stage II package includes clutch + cams I believe...

 

That was assumed because we had no idea that Subaru would "loosen" up the rear end. Let's also not forget that there was another reason the 04 Sti was assumed faster than the 03/04 Evo was due to its HP advantage.

Now that the 05 STi has Spec. C suspension bits in the rear, it is clear that was all that was needed to put it on top of the 03/04 and I would assume 05 GSR (since the MR beats the STi barely).

Just my .02 cents. And by the way, I seriously LOVE both cars and belive that the best way any real enthuasist should pick one of the other would be by flipping a coin.
