I'm very interested in how these engines are tunable. I was just thinking about this setup:

Evo X Turbo + FMIC + Tune

What if it was tuned for 280HP for reliability? Just to fill in the missing power in the 5,000-7000RPM range or would this just push the band up top instead of evening it out?

 

If it was a 5-speed it would be simple but the tuning is more difficult with the TC-SST and the Ralliart uses only one boost control solenoid compared to the EVO X so it will be more difficult to control higher boost levels consistently. I'm sure it can/will be done it's just that the car and technology is so new that you would be pioneering it but someone has to do it.

 

Pretty sure this can be done, just have to wait for ECUFLASH and change over the boost solenoid to the EVOX one (or an aftermarket).

The engine is supposed to be the same, most likely the ECU is as well. As for the TC-SST, it's the same one as the MR internal wise right (aside from the programming?) If so, you should be able to get the same amount of power before as the MRs.

 

Taller 5th/6th gears.

 

Almost. Different 5th and 6th gear ratios.



Edit: Ah, beat me.

 

I was just curious. This seems to be the direction I would want to take first once things become more clear with the transmission. Higher RPMS in the Ralliart sounds cool, but it feels significantly slower then staying in the 4,000-5,000 zone. EvoX Turbo would correct that I would imagine and the dyno's would look a lot like the EVO's. The TQ and HP numbers creating an "X" right? LOL

Not to mention the cost of a used Evo X turbo. I've been looking and they seem to be about $650 for one used and low miles.

 

as you can see from the threads addressing RA performance (or lack there of) first we need some decent tuning tools (ecutek, cobbs accessecu, or ecuflash) to be able to reflash car, most importantly override the transmission torque protection, then,..

let the mods begin.

P.S. i have nothing against buschur, ams or anyone out there creating parts first eventhough i think that parts should be tested and optimized on dyno, using tuning software

 

Just thinking about what parts would make the Ralliart stand out on the road and this seems like a great first step(Evox turbo, FMIC, tune).

 

yeah i posted the same question a while back, just need patience,

you cuz you already own the RA

me because i am trying to decide b/w the X and RA

 

We have baselined the car but we are waiting for some software to flash it. I have all the parts built, but we are going to hold off on testing until we are able to tune the car to show real gains with proper tuning.

 

If your going to void your warranty there are a plethora of aftermarket 4b11t parts out already. Why not stroke the motor and put in bigger cams.

I'm not sure how well the 4b11t cylinder heads are cast. There should be some room for a good port. A 2.2l stroked Ralliart with cams sounds unique enough right now, without giving anything away. Though I'm not sure on the availability of MIVEC cams.

 

I was sticking to exhaust until I hit 36,000 miles on her and then turbo/fmic.

 

As soon as someone finds the real limits of the SST, the engine mods will be a piece of cake.

 

i say buy a evo 8 or 9

 

Keep in mind that to replace the FMIC you either need to buy a Ralliart-specific part or convert the entire intake tract over to the Evo system. I think the turbo will bolt right in but it's a 100% sure thing, remember, there was a time when people thought aftermarket Evo exhausts would bolt right in but apparently the two systems are slightly different. The only thing that could present a problem is the TCU, if it's engaging the safe mode with a simple reflash, you can bet it will be engaged once you get the extra power that a bigger turbo, FMIC and tune will give. If you're not doing this in the next month though, one of the big tuners on here will likely have cracked the code and figured out what can be done. 280 HP is easily possible, with just the Zchip you can get that. I would shoot for 330 HP and see how that works.
Edit: Something you might want to keep in mind is what you're going to do with the car. If you just want more power during your day to day driving, I would suggest you keep the stock turbo and just mod around it (exhaust, FMIC, tune, maybe cams) rather than switch over to a larger turbo that will give you more peak HP and torque but that may move those peaks higher up. How often are you at 6000 RPM? I'm in a similar situation as I have to decide whether I want to keep my stock turbo or move to the STI turbo. It's a really hard choice.
