Talking How TO Turbo your car!

Well I've got some very good news.

For those that don't know... I have a 99RS with a Minnam Turbo and Vishnu Performance TEC-II and all the goodies that go along with it.

I just went to the dealer for my 30K service the other day. I found a really good Subaru Tech at one of the dealerships down here. Anyway... he went over the whole car.

Most important bits of info:

The transmission fluid (never been changed before) was fine... nearly (meaning 1 or 2 specs) no metal on the magnetic plug.

The compressions was just fine.

#1 - 190psi
#2 - 195psi
#3 - 190psi
#4 - 200psi

Which means in order of how the cylinders were getting abused pre-vishnu fuel rails is correct.

The pressure drops slightly in the path the cylinders get fed which is 4,2,1,3. (200, 195, 190, 190)

But I think my engine as just over 21K TEC-II turbo'd miles is living proof that if you set your system up correctly the car can, and will, last a very long time.

-Nick

P.S. Watch my car not start now when I leave work!

congrats, I hope to have similar luck, albeit without the TECII system. How much boost do you run?

Glad to hear it, Nick ! I've been tempted to make a similar post lately, just 'cause I'm so pleased with the way my car is running and how absolutely reliable it has been. I've got the same setup you do, running 10 psi on my '00. I average ~100 miles per day in my car and just passed the 46k mile mark, 27k with a turbo. My compression tests the same as yours, between 193 and 205 on all cylinders. The amazing thing is the "better than stock" driveability. Installing the Wintec2 chip made things so much easier for me due to the auto-tune feature. Just pick an A/F ratio target and drive The weather has gotten quite cold here a few times recently and it has run flawlessly whether the temperature is 30 degrees or 90 degrees. I'm totally satisfied with this car.........well, maybe a little better choice of gear ratios and a limited slip front diff would be nice

Nick-

That's great to read...somebody actually bragging about turbo reliability. Couple questions: How much boost are you running? How often do you drive the car hard and really engage the system?

Thanks.

17K turboed miles and counting. Of course, now that I've said this, my motor will mysteriously self-destruct as soon as I start it this evening too.

MY99 2.5RS, 7psi, TEC-II, dyno verified 230hp, 245ft/lb at the wheels

oh yeah, 26mpg highway, 20mpg city. I need to work on that though. Shiv is claiming he gets 30mpg highway! Hm.

I have almost 40k turbocharged miles. 30k on the last motor and about 10k on this one. It's only fair to mention that the last motor had over 150k when it went out.

5psi, no engine management and spiking boost way too much on the first motor.

For motor #2, there's a better up pipe, resolved the boost spike with a deltagate wastegate, intercooler, and still need to hook up the Field SFC.

Just set your AFR targets during cruise conditions to 17:1. The TEC-II's AFR bar graph (in the engine monitor screen) won't go back and forth rich/lean anymore. It will stay on the first two or three "LEDS" instead. It's a lean burn engine so treat it like one Keep advance during these conditions in 35-45 degree range (between 2500 and 4000rpm-- more rpm the more advance)

Just make sure that the car goes rich and less advanced as you transition to heavier load (maybe above 85kPa or so)

And then keep your foot out of the gas until the next fill-up!

Cheers,
shiv

Shiv-

Is it true that you won't be making anymore complete 2.5 turbo kits after this first group buy you are organizing? I was planning on purchasing one from you (with electronics), but didn't want to move on it until after the ski-season. Will you have availability in the Springtime? How 'bout plans for a kit running a TEC-III next year?

Thanks.

I'm running about 9.5 psi on a daily driver.

I only put about 30-50 miles a day on the car... and a portion is moderate traffic so the car sees a decent amount of stop and go.

I don't really push the limits of the car to often, but I'm no stranger to WOT. I DO NOT baby the car either. But it sees no track use though.

It's just nice not to have to drive the car WOT or 1/4 throttle about 90% of the time. The car has gobs of power pretty much all through the range.

Don't worry ScoobySlack I wasn't talking about CarTek. I was talking about this guy Tim (the only Subaru tech) at the Delray Beach Subaru Service Department. He's old school subaru and he's from Canada. So you gotta trust him, eh?

I don't like there warranty/service manager though... woman who is a PITA. Next time she gives me lip for staying with the car in the service bay I think it will be time to get her business card and make a few calls to SOA.

Why does that seem so high to me? Not that high is a bad thing, but... hmmmmm...

The specs on a MY00/01 with 10:1 compression is 165-180psi for compression tests, but you've got a MY99 that is 9.7:1 pushing around 190-200psi. Thats either a hell of a fluke (and a damn good short block to start with) or I'm mistaken.

Well damn... congrats, Nick! I wish my motor was in anywhere near as good shape as yours!

Compression specs in the workshop manual are always lower than what they really are in the field. Probably because the OEMs want to keep people from making warranty claims until things are seriously bad. From what I've seen, normal MY99 numbers are 185-200psi. Normal MY00 are ~5-10psi higher. Of course, a lot depends on the kind of gauge you use and at what altitude you are at. Also, depends on how hot the engine/oil/etc,. is.

shiv

that and the starter spins the engine at a faster RPM than is specified in the FSM for the compression test. higher RPM = higher compression reading.

Default Tuning...tuning

Awe, it's all in the tuning. Not everyone's engine blew up. Remember 59k-110k of turbo/nitrous power. Woohoo!

Congrats Nick! That's impressive man. I hope everyone has just as much tuning prowess as you. I've always wanted a Tech II. *sigh* Still do! $$$ is running to low though.

Great to see a thread like this.

You have offically returned the plans of a Turbo to my cars future.
Cost wise, Staying NA was going to be just as expensive as doing the turbo and engine managment correctly.

YAY !! I can go back to my turbo dreams

I second Rovers request for a happy springtime Vishnu turbo kit part #2. No need for special prices. Just a chance at picking up the new kit.

Even if shiv's saying no more, we can all count on SHIV to come through, right? Afterall, he said he would offer a kit, and wholla, some lucky individuals are now drooling once again in anticipation of the new kits. Vishnu performance allways comes through so why would anything change, right

You dont have to promise, but at least let us hope Shiv that ya might change your mind.

Cheers,

[don't mind the tangent, guys ]

shiv - Doesn't that seem strange to you, though? I mean, you're a numbers guy... if you're starting with atm in the cylinder, compress it 10x, wouldn't you end up with (10*atm)-atm ~132psi?

But then, looking at it again theoretically, aren't you even lower then that since the cylinder needs to create a vacuum to pull in a full cylinder's worth of air and the valve probably actually closes before it gets to atm within the cylinder, or even possibly the valve stays open for a small amount of the compression stroke?

Seems to me that a motor that compression tests to 175psi would, by those theories, be running about 12.9:1 compression.... *shrug* Most likely I'm missing something, but I can't figure out what.
