Default WRX HP upgrade TurboXS kit verse Cobb Tunning Kit?

I want to add some HP to my car and I want to do it this spring. I know that both TurboXS and Cobb tuning have kits that can be purchased. I was wondering if you guys had any suggestions of which one to go with.

Which is better? Which is safer? Which is more reliable?

I want to get the car up to around 260-290 HP. I alos don't want to do any really major changes like a new intercooler or anything like that. Also I am looking to keep cost down as much as possiable. But if the Cobb kit is that much better than the turboXS then price may be worth it...


Also can you do the stage 1 and 2 kits by yourself for the TurboXS kit?

You prolly wont go wrong with either, but you also cant forget the vishnu stage 0 kit.

Personally I'm going to be giving cobb a call in the near future.

If I were you I would go with the turboXS setup. You aren't that far away and you can get your car dyno tuned.

if your looking to save money, you could get the turboxs kit, some silicone intercooler hoses, intercooler water sprayer, and a dyno tune somewhere. All that would probably cost a little less than the cobb kit and should be apporxmiately as safe/reliable.

otherwise, just get the car to cobb tuning, hand them $3k, and youll have all the goodies and a dyno tune.

Ok so what would the final cost be if I got a Cobb stage 1 kit fully installed by a Cobb shop? (parts and labor)


What would the final cost be for all the parts and installation for a stage one and stage two turboXS kit? (parts and labor)

Hello,

Joel here. You've never heard of the Vishnu Stage Zero? Oh boy, don't let Shiv see that post - means I'm not doing my job! Seriously, though, the Stage Zero consists of an up-pipe, pulley kit, manual boost controller, sparkplugs, and a unichip, programmed for whatever mods you have. Do a search for "vishnu" and you should have a few weeks worth of reading...

If you want more information, please feel free to contact us (email sales@vishnuperformance.com or call 925-964-9233). If you have technical questions or questions that everyone would want to see answered, go ahead and post here.

Joel

I'm not sure but I don't think there is a cobb tuning dealer anywhere near this area. That is why I suggested turboXS. When I get my rex I'm going to have my car setup on the dyno for the way I drive and the parts I have..

Like jmott said, $3000 installed and dyno'd.
Stage 2, $1700, un-installed, non-dyno'd.
Performance is about the same, but even TurboXS recommends a dyno tune. If you live close to TXS, go there, to get it tuned.

The Vishu 0 is compareable to the TXS 1, not the TXS 2 or APS 1.

So which kit is the best? CObb-TurboXS-Vishu?

TurboXS- said they do not do the exhaust install. SO I don't know how much the install would cost for the stage one and two kits.

Cobb- with install 3K. Is that right or is it more or less.

Vishu- I have no idea what the cost for the kit is or for the install.

I need more detailed info...

Is that possiable to do? Can somebody ecplain what is in the Vishnu kit? How can I do all that stuff without taking it to a shop?

I think that I am leaning torwards a COBB stage one kit casue I can just go there get it done all in a day or two and get it tested out and not have to worry about getting a shop to do it all...

Hello,

The original post requested information on getting into the 260-290 hp range while ensuring safety and reliability. As many of you know, Vishnu Performance prefers not to deal with converted-to-flywheel-hp-numbers because there is no common consensus on what is the most accurate way to do it. The way we believe is most accurate (fixed drivetrain loss) puts the stage zero in the area of 265 hp. The way that "sounds" best (percentage drivetrain loss) puts us in the 274-278 hp range on the Stage Zero - but we feel that's overly optimistic.

The Stage Zero includes a unichip, up-pipe, pulley kit, boost controller, colder spark plugs, and tuning of the unichip specific to your listed modifications, based on the dyno-testing, flow-benching, and data-logging we have done. Jasno999, as to your concern about installing the kit, we actually suggest that customers do the installation themselves. There is nothing hard about it. The up-pipe installation takes some time to do (some people set aside a weekend, most shops charge 3-5 hours, some of us can do it in about 2.5 hours), but once you do it the first time, you never have to do it again, even if you get bigger turbos, a new downpipe, etc. It would be painful to do a new turbo and then have to go in there again to have to do the up-pipe once you decide you need to change that anyway.

The installation of the Unichip involves cutting three wires and tapping into 2 more. It's a 15 minute job, and can be done as "stealthely" as you'd like.

Preliminary testing on Stage One, which should be available shortly, is showing us that we conservatively expect to offer another 30 wheel horsepower. Once again, we're working on ensuring that Stage One maintains our large margin of safety and reliability - a reputation we have no interest in losing. We are currently working on determining the horsepower limits we can safely reach with the stock fuel system, because we don't want Stage One to require fuel rails and injectors... Again, we're reluctant to "chose" a flywheel calculation to go with... Stage One will likely provide 290-320 hp depending on how you want to calculate it and what we find the stock fuel system to be capable of producing.

Depending on when I'll be relocating to Indianapolis, I might just end up going with vishnu stage 1....

I want the dyno tuning tho...

cobb in rockwall is only 4-5 hours away, but I dont have a day off to go drive there (in fact, I havnt had a single day off work in 31 days now...ugh...).


I still havnt gotten a second opinion on the cobb-approved shop in Columbus Ohio, if that place is cool I'm going to wait till I move to indy and just go there.

Yes the Ohio shop is a far drive for me but it would be the place that I would have to take it to if I wanted it done. I got a estimate for the kit plus installation and testing. They said it would be about $3,080 for the stage one kit. Not horriable especially for getting it done right and tested.

I need to know if the Ohio shop is any good. Has anybody gotten the Cobb Kit from the Ohio shop yet?

My opinion echos everyone else's: go with whomever can dyno-tune the car for you. If you're not close to anyone, I would go with TXS or Vishnu. I personally had Cobb install and dyno tune my Unichip, and it runs great (I also have M2 up-pipe, full exhaust, TMIC, and GFB BOV. My car runs great on the Unichip boost controller, and I have NO boost spikes, even without a MBC (yes the car has been driven in VERY cold weather this month). However, if you're not going to have the car dyno-tuned, it seems like Mark or Shiv are better at sorting out potential issues over the phone as opposed to having the car at their facility. Just my opinion, I could be wrong, it's been known to happen.
