Wouldn't you at the very least need new rods?<ul><li><a href="http://www.atpturbo.com/root/releases/release050304.htm">click</a></li></ul>

I would like to think they knew what they were talking about, I hope they do in fact. My experience tells me thay do not tho. Good luck to them, I certainly could have saved 30k$ if I had beleived this true. But more than 1 hi-end engine builder said it wasnt possible, my experience agrees. But nevertheless good #'s and good times. Just have a big basket ready to hold the parts.
Rods

was doubtful, hence the question

30+ psi, C16 fuel or Nitrous?

If this car is so fast and makes so much power, dont you think ATP would have used the 1.8t challenge to prove it? Only thing is that the 1.8t challenge cars had to run a cat and run "unleaded fuel". Which might have been why they were not there and it was held right here in their own state of CA.

Does seem like an interesting turbo, powerband looks a lot like mine feels, but that one levels off and mine seems to make more boost till 8k redline, spikes boost at 31.7lbs at 7900rpm. I will have to get a dyno run, but the turbo seems very similar to my k26/k27 hybrid as far as where it does what xcept at end.

In my mind, that fact pretty much sums up why they might not have been at the challenge with it.
It's a one off 'shop car' and they don't care if it goes boom during experimentation. The fact that it has held up thus far speaks more to that particular engine than anything in the tuning or hardware.
Most 1.8t engines would go boom well before that power level. Some go boom at the power levels of the current Stg 3 kits .. others may be better balanced and have rods and crank that more closely fit the ideal. I certainly wouldn't bet mine was in that class, however.

Tuning really is the key to making power on any motor. As long as you avoid preignition, these motors have been shown to be pretty durable, as long as you aren't stupid.

And in case ya wanna know my early 92 Talon AWD ran a 20g Turbo, external dumped wastegate, VPC (with SFAC I), 25psi, 660 injectors, 3 Buschur turbo back exhaust.

And my Audi...it still isnt chipped, yet. :)

That is called "BOOST CREEP" not a spike. Which means your wastegate is too small for your setup.

with the GT28rs kit. At the 1.8t challenge a "cat" and "unleaded fuel" had to be used. But I am pretty sure that car does not use either.

Just so you know, the owner of that car also owned the Yellow FWD 2.0 GT35R car that also used to wear the same CA lic plate and also had all the same S4 body parts on it.

for boost or what type of fuel?

...i love trying to tune the 2.8 ever since somone told me it was untunable

had cams mild port head and a large trim t3/t4e that was mildly clipped. car was ungodly fast and had a seven bolt main. crankwalk was surprisingly minimal he sold the car running like a champ and from what i understand the car still has the original bottom end to this day.

we tuned it with old school S-AFC, VPC and a Apexi timing controller. those were the days :-P

damnit now i want an eclipse again.

since it was caused by a POS pressure valve DSM installed in the clutch line between the main and slave cylinders. That valve also caused the issue with the clutch pedal falling to the floor making a left or right hand turn and if you just placed your foot on the pedal at a light.

450+ whp GSX's are a dime a dozens since you can get that with just a few bolt on parts and some easy tuning.

I doubt the poster was referring to the Gt28rs variant in asking about the internals surviving. After all that is only 40-50 crank HP above the base APR Stg III or PES kits... only 20 or so above the APR car on race/race... and only a couple of 10ths +/- quicker than the best Stg III race/race runs. It should be OBVIOUS to even you that he was referring to the 11.97 second variant which is touting over 425 whp. Which, as I stated, was not running at the time of the 1.8t challenge.

but they DO tell you what their GT28rs kit does on their webpage with the info to your questions.

I think they explained well what their kits do on they're web page(I believe 12.5 on gt28rs) and then showed us some good old drag racing. Kudos to them for raising the bar.

for the crank thrust bearings are located in the main journals. the oil squirters themselves are are check valves (pics are attached) which may be what you are talking about. check valves can be an issue as when these squirters get contaminated they can get stuck open releasing pressure (lubrication) on the thrust bearings. at idle this is not an issue but as more and more stress is placed on the engine the uneven amount of pressure can cause crank to move unevenly (as though its coming out of balance) which is what is considered crankwalk. i think you can assume what happens after that. basically what i am saying is that crankwalk is a major is for 2G eclipses it is the achilles heel of what would otherwise be a relatively bulletproof engine.

as for 450whp eclipses being a dime a dozen we never came across one that even came close to being as fast as this car. it ran low 11's all day long. he ran a 12.7 in the car on a shake down run the second day we had the car running with base line tuning on 91 octane (2.5" exhaust with a HFC).

we are now working on a 3.2 liter VG30DETT utilizing GT28R's. car is running perfect, no we have to sort out the fueling for it. my friend is not sure if he wants to sell the car or not so the project is kind of limbo.

Which goes on the dyno any day it wants and gets full custom tuning. Now why dont you ask them how much boost they need to run to make that power or run those times, if it was tuned for pump gas, unleaded race fuel or leaded race fuel? If it was running the same exhaust setup it has now which is not a full exhaust, no cat and most likely runs their dump valve.

How much info do you think you have on either of these setups on this shop car? Because the day it was at POMONA it ran 13.7 on its first run making 26psi. How much more boost do you think they needed to push out of that turbo to run 12.1?

Since they were claiming that the GT28RS was running faster times then what ran at the 1.8t challenge. But then they do run at SAC which has been proven to be a much faster track. Fact is that a friend of mine just went to SAC raceway and pulled .5 seconds fast and 3 mph quicker then he ran at Fontana on a cold night.

Because I have one with 180,000+ miles on it that is driven every single day of the week. Part of what you say might be right, but the issue with the clutch will cause the crank to be pushed to one side since pressure is held in the small valve in the clutch hydrolic line. This in time will cause the crank to wear incorrectly causing the crank to walk. The fix is to remove the stock clutch line that runs from the slave cylinder on up to the passenger side. This line included that stupid part mitsubishi decided to put in that the 1g did not have. You replace that line with a standard braided line. After doing this I have never had any problems with the crank walk and it has been about 100k miles since I put it on.

The reason I said dime a dozen is because there are 9 second 2g's and tons of them running 2.4 and 2.5 liter conversion kits.

Believe me I am knee deep in the DMS world since I have owned one for well over 10 years and have a ton of friends that run 1g, 2g and EV08's making from stock power to 700 whp.

...went to a junkyard found a c32amg that had flipped several times paid $50 for the blower and intake manifold...now im in the process of machining a new one that will work for my car...lots of fun if it works...and a lot cheaper than that $5k one...ill still need new injectors and what not but

thats a surprise.

"Because I have one with 180,000+ miles on it that is driven every single day of the week."

It's pretty hard to drive a car every day of the week when you blow up the engine.

So the real question is...are they both 13 sec. cars with 25k in performance upgrqades?

to fix the spun bearing. The car has 180k + miles and is 10 years old. It still runs the stock t-25 turbo and only has a after market muffler on it so there is no real mod money spent on my DSM and my audi runs 12's where stage 3's are lucky to get into the 13.9's on 104 octane race chips.

can we hear about how great you are some more? lol

.<ul><li><a href="http://forums.audiworld.com/performance/msgs/71664.phtml">Poor Mike and the horrible tracks he has to run on :-(</a></li></ul>

including every single stage 3 that has run at my tracks and I was doing that with the T28 kit too.

I know you just cant stand the fact that all the stage 3's on race chips run low 14's and just dip into the 13.9's at best. But guess what, it is a FACT. I also love how the stage 3 GTI's tested here also cant run faster then 13's even after they use the NHRA adjustment table to give it a "sea level" ET.

Dont worry I laugh every time I see any APR POS products run at my track, since they are always much slower then APR claims them to be.

Get your facts straight.

I miss those, I especially miss writing my "war stories" to post those after a good weekend.

As it is you wont be getting any of my money. If I wound to 8500, the boost would go to 36lbs. Pls. do not assume the limitations you have on your engine and turbo apply to everyones. I run a big enough wastegate and a seperate pipe to the bumper 2" pipe.
WG creeps ass. That is where my boost tops and the WG opens. Is this 4 banger your 1st effort building a turbo engine? sometimes you seem a bit out of the loop. I can buy a bigger turbo and the top boost is 40, is that WG creep?
Get out more often and quit busting everyones chops. You would think your life revolves around these little cars. Put the damn thing on a road course and see what they were really built for.
Please do not feel the need to comment on this please please please.

I also spend more on a block than most have in their cars. Which is also why I dont have the limitations some speak of.
Rod

My car has been on a road course, so I guess your the only one out of the loop.

No its not, but I dont use something to ramp my boost up to increase power in the higher rpm but then I guess you do and from the looks of it so does ATP.

Your car has been on a road course, but without you driving it, so you might as well start "Pelican Limo Services" and just have other people drive your car.

Quit whining and get out there. It's a lot more fun than drag racing and you break less stuff.

BS you break less on a road course then at the drags. Every car that broke at the 1.8t challenge was on the road course, unless you count the 1 blown up motor on the dyno.

Even people who hate on APR, will never call their products P.O.S.

I can say. that the APR stage 3 has more hours spend on engineering and development than you can even imagine. way more than you car btw.

That kit is Stonger than anything out there, anywhere Find the detail, and quality anywhere else? I dare you. . Just becuase the APR customers have fast, reliable and trouble free cars with customer service, doesnt mean you have to hate.

How long has your car been in the shop? vrs a 3 day APR install.. Btw. come look at what the latest kits are running. Drive one, i bet its more of a pleasure than the drag racing audi you have there.

You should have gotten an EVO..

or an S4 since a stg 2 will do 12.9's
