Default Vishnu Performance Stage II

OK here goes. This kit f'ing rocks. You need to have the Stage 0 first, and if not, you need to purchase it as well. I paid for Doug at Diablo imports to install everything, and am seriously happy w/ the service that I recieved from both Doug, and Brett/Shiv at Vishnu. The muffler took a couple days longer to come in than we thought but when I got the car back I was flabbergasted. It's amazing how fast 250 wheel horsepower feels! The place you really feel the power is up high, accelleration (on the track of course ) past 100mph is worlds away from the accelleration of the stock car. If you're serious about power, and upgradeability too (Stage II leaves lots of room for more power) you MUST check this kit out.

If you have questions about how the Stage II feels/sounds/runs, post them here!

did you get the divorced wastegate? Also, do you know if an axle back will bolt up to the exhaust you got... my feeling looking at the pics on the site were that it won't.

Also, how much was the install? I figure it ain't cheap...

BTW, kudos to your upgrade. I personally think that Shiv's philosophy on engine management meshes most with mine, and that's probably the route I'm gonna take in 2003.

i dont know much about engine dynamics and all, so i have a few noob questions (please bear with me)...

1.) Are you using a EBC or MBC? And what is the max psi you can use on 91 octane gas?

2.) Are you using a unichip to control fuel and whatnot? Or are you using something else to control fuel?

3.) Were some engine enternals replaced to compensate for the higher output in power? If so, what parts were upgraded?

4.) Are you using an aftermarket clutch? Or are you using the stock clutch/tranny/etc.

5.) May i sit shotgun in your car sometime?

sorry i have a lot of questions. As you can tell from the left, i am a total noob.

I didn't get the divorced wastegate - I wanted to be sure that this thing will pass smog and Brett at Vishnu is of the opinion that this one will "sniff" cleaner.

I don't know if an axle-back will bolt up - I like it the way it is

Doug at Diablo imports got me a really really nice price on the install. I promised I wouldn't say how nice but all I can say is call Doug and he will definitely hook you up. Doug is at (925) 676-2782 in Pleasent Hill, right by Walnut Creek.

And yeah, I looked at Shiv's track record before I got this installed, I've talked w/ him a number of times and really like his philosophy - safe, reliable power on street gas - sure works for me

The Stage II kit comes with MBC (Manual Boost Controller for the newbies), Unichip. The max psi you can run with is more a function of how well the fuel/air mix is controlled than what octane you run as far as I understand. If you upgrade to a nicer engine/fuel computer, I'm sure you could go much higher than the 15psi it's set at now. Or maybe it's 16psi - either way, Shiv tuned it for me and my Subaru-supplied boost gauge is in "mpa" so I'm not completely sure.

edit: just spoke w/ Brett @ vishnu and he says with this setup you can go up to about 19psi 20psi before you haveto upgrade to a higher octane than 91.

No engine upgrades are necessary to handle the extra power. Shiv is ultra careful when he designs his Vishu Performance kits, and takes extra time to make sure your car will run happily for many thousands of miles.

I'm using the full stock tranny/clutch/diff. You already can put quite a lot of stress on the clutch w/ the stock engine. I'm sure you could blow your clutch real fast going to the drag races every weekend with the Stage II, but only a little faster than with the stock clutch. As with anything, moderation is the key. If you drive slowly in first gear to get some inertia to help negate the incredible forces put on the clutch, it wil last longer. If you drive like a maniac and drop the clutch from 6,000rpm at every light I'm sure you could blow any clutch eventually For the occasional light HPDE track day and regular street work, I feel confidant my clutch will last for a while.

Oh and you're TOTALLY welcome to make a drip down to the bay area and sit shotgun for a tour around my favorite corners and freeway onramps - I'd be more than happy to spend more time in my Subaru

I don't think Shiv is working on anything specifically for the MY02 RS, but I do know that the Tec II kit he used to sell made a very usable power difference to my N/A MY00 RS. I'd give the website a look http://www.vishnutuning.com/ - their contact info is here

Default Stage tw0 (2) install in progress

aussiebrydon & all:
Vishnu Stage two (2) kit install, and suspension, tires/wheels and morrettes, etc are in progress on my WRX '03, as we speak!
I also did some due diligence, and tried to followup threads on i-club, spoke to several competitors, including M2 performance, but felt that the engine management-tuning & AWD Dyno experience was vested in "the man". Shiv/Brett at Vishnu tuning have been great to work with!

BTW:
1. What about turbo lag and torque, or "seat of the pants feel" of the car? Any other impression of the car compared to stock and any other performance cars you have driven (or challenged)?
2. Any CEL's?
3. If you had to do it over again, anything you would change or modify?
Thanks, interpath

i dont know for sure, but i imagine yes it is possible. As the first post states, there is a lot more room for power.

as for me, if i ever have enough money for this investment, i would like to run an STI top mount

I'll add my .02 worth. This system is a complete departure from even the stage 0 when it comes to "seat of the pants" feel. Lag feels a little greater, but when boost comes on, around 3200 for 17lbs that mine is running as of the moment, the tach becomes a blur and you tend to hit redline real fast. And, it pulls that way through all gears. Off-boost torque also seems to be much better.

Sound and quality of the exhaust system is something I have yet to see from any other competitors, but you won't be able to use your own axle-back without modifications to your pipe as Vishnu's uses a special clamp to connect all parts of the exhaust together. This setup should eliminate any exhaust system leaks.

I'm sure a front-mount intercooler will work just fine. I'm pretty sure that Vishnu has started to sell their own Top-Mount that flows more than any other currently on the market. (I seem to remember a couple of people have already procurred these)

As with all larger turbo/injector motors, mileage has suffered around town. Your mileage will vary depending on your Greed for Speed . An unexpected bonus I discovered was vastly improved mileage at freeway speeds. Almost 3mpg more on average.

Summary: Get it, drive it, enjoy it. Vishnu, awesome job!

I have a shiv tuned stg II but with the Cobb exhaust (because it was available), being done by Doug this week (Diablo Imports).

He also did my stage zero, and I could hardly feel the difference between stock and stage zero except on the Freeway at high speeds (above 70) it was a little smoother.

Is the difference to stage II more noticable?

Thanks,

If you cant feel a difference between stock and stage 0 something is wrong. I didnt even put the piggy back in at first and still felt a drastic difference from around 2800RPM and up. After I installed it was even more pronounced. ANyho...sorry to get off topic, but I'm definitly going the stage 2 rt. and am glad to see its getting good reviews.

Thumbs up

Went to Vishnu today and mentioned my stage 0 prob and he thought I should have come to him as soon as I thought I had a problem - well it runs MUCH better now - way smoother and pulls harder longer - def better than stock.

Unichip map was screwed up - Shiv didn't just load a generic to replace it though, he put it on the dyno and made a map custom to my setup and it ran way better.

If nothing else, you have to give Kudo's to Vishnu for service. Shiv won't let a problem go unsolved.

yeah Shiv took care of me, I'm really glad I'm local but I assume any Unichip programmer could have done the same.
