Thumbs up Imprezer's review of the Detroit trip

Well I finally re-read all the posts I made about the car and going to briefly going to tell you the key points about it.

1. The headlights look good in person. Not as round and big as they look in the pic.

2. The turbo used on the car is a tiny Mitsubishi TD04xxx non-ball bearing unit.

3. The car comes with nice SS pedals.

4. The shifter feels shorter than the RS one, but not as nice and notchy as Kartboy's or any other short shifters.

5. The factory gauge pack is goofy. Boost, oil pressure and water temp gauges are 2 small.

6. The steering wheel is almost the same as the JDM WRX one, besides the MOMO logo being a bit yellow.

7. The seats are awesome. Made out of very good material. Same material used on the STi seats, but without red.

8. The driver's side front seat is hight adjustable via lever. Very nice feature for all the shorties.

9. The rear seat doesn't fold, but you can access the trunk from the cockpit via an opening in the middle of the rear seat.

10. We have a trunk light.

11. Remote release gas tank door is there.

12. The rally blue is more rally blue that the MY99 blue. Looks nice.

13. There is that "thing" above the rear view mirror that can be folded down to prevent sun from getting in your eyes.

14. BBS wheels look awesome.

15. All the head back exhaust parts seem to be identical to the pre-MY02 WRX. Not 100% sure on that.

16. There are 2 vents on the rear deck that connect the trunk compartment and the passenger compartment. I wonder why?

17. The gauge cluster looks nice and the dials are easy to read.

18. Stock foglights are the same size as the RS ones and they sit too deep inside. The car just screams, "PI-PI-PI-PIAA".

19. WRX with rear wing looks much nicer than the one without it.

20. In order to pass the emissions, SOA implemented some special valve that is remained closed at idle and low RPM and helps to keep the Green Peace people happy and at high RPMs it opens up and while incresing volumetric efficiency of the engine, therefore increases the output, it also creates ventury effect and helps to have a leaner more efficient burning of the air fuel mixture.

21. We will have problems fitting the front strut bar. The AC lie goes right above the IC and will interfer with the strut bar.

22. The MSPR is where it should be.

Thats about it. I will try to remmember more.

>2. The turbo used on the car is a tiny Mitsubishi TD04xxx non-ball bearing unit.

Ahh finally, some REAL information for us interested in actual performance, and not the *#@# cupholders.

The TD04 housing is WAY to small for this engine, and it's low compression ratio. The 2.0 litre 4G63 DSM engine has proven the best all-around street/strip turbo for this size engine is the TD05-sized one, with a 16G compressor wheel.
With the simple swap of this turbo, and a 3" exhaust system, 350+hp is realized by even mediocre tuners on the DSMs. This results in mid-high 12 second quarter mile times at between 105-110 MPH trap speeds.
Considering that the WRX is at least 100lbs lighter than a DSM, and with it's lower compression ratio can probably handle more boost, I would think mid-12 second WRX will be an easy accomplishment for under $2000 in bolt ons.

It will be interesting to see how the ECU and fuel system on the WRX will like this. Will we need a new fuel pump? Injectors? Manual Boost Controller? ECU upgrade?
So many questions....

No fold down rear seats?!!!!!! What are they? GM?!!!

I know you nuts prioritize 300hp and 15"discs over 'trivial' matters like this, but I AM real buyer material. I'm always carrying junk around in my cars and I really appreciate rear fold down seats. As far as innovations go, they are up there near microwave ovens, those semi-abrasive spongy things you bath with, and credit card swiping at the fuel pump. DAMN!!!!

You can always look at the WRX wagon. It has fold down seats.

At least there is a pass through for skis. They are the only thing that have REALLY made me want the fold downs. I've lived w/o fold downs for 4.5 years, so I'm pretty used to it at this point.

Overall it sounds pretty nice. Can't wait to see it with my own eyes. The only thing that cocerns me is that part of the seat that folds down in the rear middle. What is going to keep the Trunk Monkey from getting out of the trunk?

Disturbing!!! As this could add credibility to the rumor I heard that this is an EJ20 and not an EJ20T and will not handle more than 14lbs of boost.

If you're referring to the open deck vs. closed deck design, I think it was Trey Cobb who informed me that before the v.5 WRX, all of the engines were OPEN (O-P-E-N) deck.

He also didn't seem too concerned about turning up the boost, but he did talk about the MAF problem...and that an aftermarket MAF will be required for a cold air intake system.

EDIT: I am a freaking idiot.

Some random points:

Rear seats that don't fold down add to the body rigidity, esp. since they are so close to the rear strut towers.

Blitz already has a cold air intake that appears to use the stock MAF. I posted a pic of it in another thread here.

All cars have a venting system between the trunk and the passenger compartment. Don't know the exact reason for this, but it is not a Scooby specific thing.

For the gauge pack. I wonder why SOA doesn't use the STi GeNome Part. It fits better than the one seen in the auto show pic (looks like SOA modified the old gauge pack to fit to the new dash :-)), and looks way better.

STi GeNome Gauge pack features Defi linkable gauges and 3 of those alone are over $800. Trust me, I have them. Add a gauge pod and you have a $1000 gauges.

does this mean that the turbo will interchange easly with existing DSM replacement turbos?

No. Thats what I don't get. I saw with my own eyes that it said td04xxx on the compressor housing. But, TD04 is refering to the exhaust side. TD04 simply means that the exhaust inlet on the hosuing is 4cm or 1.61". The flanges are different between the IHI and Mitsu turbo's and that turbo had an IHI style flange, that weird triangle.

I would say, that the best upgrade for that car would be a IHI-VF22.

You guys make me laugh

The block is open deck..

The TD04 is fitted to previous Subies over here (UK/euro Spec).

It is small in comparison to something like a t04.. more like a t28 maybe...but rememeber these are 2.0 cars

I wouldnt worry about the bore being open deck.. more liek the strength of the piston and rods...

J.

ps - Alex.. nice review
pss - You could always fit a IHI turbo
pss - I've never found any other makes of turbo that directly fit.. maybe you have them in the US ?

Please listen to Jay, The Euro and Assie models all come with The same small little mitsu turbo. The motors are the same, save for I think a small diff in ecu tunning, hince the slight increase in HP and TQ. Please be reall folks, it takes a lot or investment to make two diff types of motors for multiple markets.
As stated Blitz already has an intake using the factory sensor, as does Zero factory, Zero factory has exhausts using cats and not, Apexi has a Power FC in JDM land also. Check out Hyper Rev-Impreza mag #9.

Every thing will be OK, don't worry. We are getting the cool **** finally. I know it is hard to belive since we have been treated so badly for so long. But our time is here. Lets get to work fellas,

My thoughts, after seeing the car in person.

We begged and begged to get this car for a long time..

it's here..

why is anyone complaining?

we finally have the WRX that the rest of the world has..

if you don't like it. then refrain from buying it.

eitherway.. the engine, stiffness, interior are better than the existing RS's.. IMO.

Ken, only the old WRX came with Mitsu turbo's. I don't know for sure, but I think IHI found its way into WRX in 1995. Correct me if I am wrong, Jay.

Unless these have some new and wacky purpose, they're there so your rear deck speakers don't blow out when you slam the trunk.

Question

Could someone tell me what the differences (other than ball bearings obviously) are between a ball bearing turbo and a non ball bearing turbo? How does the non ball bearing turbo turn without having some sort of a friction reducing mechanism in place? Also, is having a non-ball bearing turbo vs a ball bearing turbo affect the turbo life? I drive a LOT and the car will see 100k miles in 3 years. I would not like to have to replace a turbo in that time. I do take proper care of my car (oil change, spool up and cool down periods), run synthetics etc.

thank you

Apparently the sedan has the aluminum a-arms. That is one reason it is more expensive than the wagon.

Ball bearing turbo's have a better bearing system for the compressor wheel to spin on. This allows the wheel to spin up faster, reducing turbo lag, and will add longevity to the turbo. Downside is they are expensive. Normal turbo has roller bearings that create more friction, resulting in more turbo lag and shorter life. They are cheaper though.

OK, here's my potentially ridiculous take on the trunk vents (having not seen them in person).

First, my Legacy doesn't have any vents from the trunk to the passenger compartment, so I wouldn't say that all cars have these. Which is not to say that the Legacy's trunk is air-tight - I'm sure it's not - but it doesn't have any sort of visible vents through the rear deck. The fact that Alex noticed these things would lead me to believe they're unusually prominent.

So, here are my two guesses, and they both relate to the WRC car. Those vents are to allow cooling ducts to the rear brakes or the rear diff. On the WRC car the rear quarter windows will have NACA ducts to suck in air and that air will be routed down through the trunk either to the rear brakes or to the rear diff, or both.

I'm basing this on an assumption that the vent holes are near the quarter windows, and are big enough to allow a useful-sized cooling duct to pass through them. So, whaddya think?

PS - I'm proposing this idea because the topic of rear diff coolers came up last week on the Open Track mailing list I subscribe to.
