Alright, This is a 6 blader with a stock 9 actuator.

I installed this turbo back in 3/09/06. I used the stock 8 coolant and oil lines. With a little creative bending, I was able to bolt it in place on the compressor housing just like stock. I also used the stock lower pipe of my 8 but had to re-position the + starter cable end to a 5 o'clock position from it's original 12 o'clock so it wouldn't hit the lower pipe.
After 3 1/2 hours, I fired her up. Checked for leaks and pressure tested the system for boost leaks. So far so good.
Now for my current tune. I was Custom Dynoflashed back in 03/04 and that's what I still have today. I since then added an AMS fm back in summer of 05 then the turbo upgrade.

Road testing,

I borrowed a friends LM-1 to see where my A/F was at and a logger to see what my timing was. Well I was tuned for 11.1 back in 04 without the FM and 20g so I was excpecting I would be leaner since I was still using stock injectors. I lowered my boost to 19 psi from 21 .To my amazement I was at 11.0 in 3rd gear and 10.8 in 4th to redline with a smooth ramp in timing to 18* at 6900 rpms. I bumped the boost to 21 and still getting the same readings. So with this data, I would say that my tune is still dead nuts even after 2 years . Either that or this 20g is flowing the same as my 03 stocker.
Only way to find out is run it right ?

Well the track (GLD) opens 04/01. After 3 weeks and 1100 miles, track day is today. I got 3 runs in before the rain came.
First 2 runs were really bad 60 ft's.
2.1---->109mph
2.0---->110

final run:
60'-------- 1.77
330------- 5.16
1/8-------- 7.9
mph------- 86.23
1000------ 10.46
1/4-------- 12.43
mph------- 111.55

So back in 04 I ran 12.7@109. added a FM 12.6@110.
So all in all I gained another 2/10 and a mph on an untuned 20g with a richer A/F.
All shifts were lifted and same as my previous runs. Straight 93 oct. still at 21 psi. on a stock clutch @ 40K.
I know some of you guys are thinking that these times and speed can be done with less mods and just better driving. Well I chose this path so there will be an unbiased results since this is done on the same car with the same driver, same sucky ashe driving.

I think it's time for a re-tune !!

Sorry for the long post. Thanks for reading.

 

After reading your results, I now have no regrets buying the 6 blade 20g. Thanks for posting your findings. Get it re tuned and let us know what happens.

 

Evo Police, you mean you'd be happy with a 1.5mph increase after adding your 20g and FMIC over a stock 03 turbo with the 9.8 hotside? I would be quite discouraged.

 

No I wouldn't be happy. It's just a nice to see that there was improvement after the install. I believe that Ted B stated he lost power or didn't gain anything from the TME to the 20g.

If there was no difference in his findings I would be depressed about the possible outcome of my turbo purchase.

To be honest I'm crossing my fingers that my new turbo will be great. If it turns out that it isn't I'll then take different measures to get more bang for buck.

I'm not a big racing fan. I'm sure someone like you who are into racing would not be happy with the above results. Me on the other hand this is just a hobby. So my expectations are much lower then yours. Not that I don't want great results. I just look at it from a leisure view. I would be more upset if my xbox 360 stopped working since I use it more then my car. lol

 

The simple fact is that if your air/fuel readings are the same or lower that is a good indication that you aren't pushing as much air or less air with the 20G then with your previous turbo.

I would take your car to get tuned on a dyno to figure out exactly where you're at.

 

Well, I can see how you do it for leisure, but if you spent all that money on a turbo ugprade, wouldn't you want a large increase in power? If you weren't expecting it, then why would you purchase it? (asking rhetorically)

The key point in your response was that Ted B went from a TME to a 20g-9-6. This guy went from a stock 03 turbo to a 20g-9-6. He didn't go from a TME...the TME is like an 05 (10.5 hotside) but with the Ti/Al internals. I think Nad would have seen the same gains, if not more, from installing a TME without the FMIC upgrade. We will have to see what happens after a retune, though. I'm not sure much will change unless his tuner of choice decides to tune him closer to 12.0 (might not be a good idea).

 

keep us posted after the tune. you are probably the first one with 20G-9 with bolt ons

 

I know. My car will sit in the garage for 2 1/2 weeks. Vacation.

When I come back I would like get tuned. AMS has a long waiting list. Al might be here at the end of May so hopefully it gets done.



Im just glad I gained and not lose power. Even with a richer reading.

 

I do see what your saying and you make valid points as you normally do. To be totally honest and not to sound cocky. I wanted something new for my car and just wanted to blow some money. I knew there were a lot of findings that this turbo might not be up to par. But I'm taking a chance to see how it pans out. If it turns out to be a sub par return, then I'm calling DB and will get it modified to a 5 fin design. If the results I get are up to my liking then I will leave it alone.

Then I'll be good for a few months until I get that itch to buy something else for my car.

 

is the 20g9 supposed to pick up much power on pump fuel? i mean, 21psi is weak, not gonna have too much for flow over the stocker at that boost level....and the hotside is almost a moot point at that boost level. just laggier

 

nice job! when your car is tuned with more boost on pump the gains will be even better. my car runs 23 psi boost spike which tapers to 18 psi on 91 octane on the 05' turbo. once you get your car tuned try 1-2 psi more on pump.

 

I probably picked up 8-10 whp on the power band just by comparing my mph to my past slips.
Got an extra 2mph in the back half so I guess I made some hp.

I know 21 psi is weak but I was running straight 93 oct , un tuned and didn't want to risk running leaner if I cranked it more.
93 is all I run and I'll ask my tuner how much I can crank it with race gas even with stock injectors.
My real goal is 11's with my current set up on stock injectors on staight 93.

It's 300rpms laggier than my stock 8. 3rd gear full boost at 3900 starting from 2500 wot.
.

 

Uh...am I the only one that sees this?

He trapped 111.0

He added a fmic and a 20g9 turbo and picked up 2mph.

That's a lot of money for 2mph

 

your MAF scales, so upping the boost won't really make you go leaner...it will add to the cylinder pressure, and put you closer to knock. also, i was talking about just changing hotsides on the 03, in reference to what warr was saying....not talking about the 20g.

 

Uh, you might want to explain that to the AEM UEGO wideband in my car then. Everytime I up the boost I go lean.
