Ok Evo 3 gears in our AWD trannys, how do they compare?

[tarantula]

Theres the new Evo 3 double synchro 3/4 gearset that the popular shops are now selling. It is said to be a stronger set when compared to the OEM weak 3/4 gears. I am in the plans on getting third gear since my brand new one broke and want to make an educated decision on which gears to put in my transmission.

So if you have it, or have experienced them, please chime in and give a review on them. how do they run when compared to the stock ratio in AWD? Does it run your engine different.? I know they are stronger but I want to focus more on how they feel or make the car run.

Thanks.

No one wants to give a review on the new gear setup?

I could tell you a little about them, but I believe you wanted customers to chime in instead. I have done countless EVO III 3/4 setups, so let me know of there is anything you want me to tell you... There are a lot of people out there with them. I am surprised no one has said anything.

No by all means tell me about them. Your input is equally valued.

Okay, what are you going to be using the trans for? Street use? Drag or road race? Can you give me any info on your turbo and engine? These gears and their ratio can be beneficial or useless depending on the car. Let me know what you have there and I'll be able to tell you what they will do. Thanks!

My car is strictly street performance. The turbo I currently run is the FP3052. The engine is 2.0 and in the near future will be a built 2.0. The fastest I've run so far is 11.82 on 25psi dropping to 23psi in the 1/4 with E85 mix. Looking to run mid 11's on high stable boost and E85. (upgraded tial springs) My fastest 0-60 time is 3.5 seconds.

Oops, just looked at your sig up top. With a 3052 I'm not sure if the ratio will help. That turbo has a very good power band so you might see a tenth or two off of your 1/4 mile times, but that's about it. The EVOIII 3-4 is nice because they are double synchro, but the gears you have now I can convert to a super double synchro, so buying the 3-4 purely for the double synchro really wouldn't be worth it. The only benefit I can see from the EVO III is it uses the stronger hub and slider assembly which will not break.

Your engine RPMs will be a little higher in 3rd compared to your OEM gear. This will narrow down the ratio difference between 2nd and 3rd so there isn't as much of an RPM drop when going into 3rd gear. This will really only benefit those with a turbo that have a narrow power band though. I can't see that you will notice anything with your setup. I would say if you are going to stick with the power you have now, use the 3-4 that you have in the trans now but convert them into a double synchro. That will make it a lot more pleasurable to drive around town.

The main things our customers have liked about the ratio of 3rd gear is it keeps big turbo cars more in the power band as mentioned above. Some customers have said they also like it when racing from a 'roll'. A lot of people that race on the street like to go from a roll instead of a stop. I don't know why... Bikes, Honda and Supra owners always seem to want a 50ish MPH roll. The EVOIII 3rd gear allows you to start from a roll at those speeds instead of using 2nd. That allows for one less shift so you can just pull away. Here is an example of a 50MPH roll in 3rd gear:

Street racing is very bad and illegal though, so we do not encourage you to do this. Another benefit of the EVOIII 3rd is in road racing. I noticed on some of the higher speed courses that I don't have to down shift into 2nd on the slower sections with my small turbo. I just leave it in 3rd and focus more on my driving than shifting the car. There were some sections where I had to down shift into 2nd on my old gear set and it killed me, now I just keep it in the same gear and put the pedal to the carpet when needed and the engine has enough RPM to make the turbo do its job.

Thank you!!! Thats what I wanted exactly!! the info you posted helps alot.
Basically I'm too traumatized in using the stock 3/4 gears and wish for a stronger gear. The Evo gear teeth look thicker so I like that in terms as strenghth.
In the issue with shifting, I always loved how my turbo spools up and just rips in second gear. Acceleration is phenominal in second and I always wished that third can be like that. In your explanation, it seems as if that would make my wish come true. In street DD days (when I do drive it) its nice to know that the car would still act "Normal since fifth is the gear I would stay in.
So I have one last question.
Third gear takes my car up to about 90 MPH at redline. Would the MPH decrease or increase with the Evo3 third gear. Forth gear is not an issue as I don't do WOT pulls in forth when I street tune.

[JackM]

You would see a lower MPH by redline in 3rd with the EVOIII 3rd gear as it is shorter.
