Looks like I should just be able to swap my STG3 compressor and wastegate over to this boltup badboy. peep the link<ul><li><a href="http://www.atpturbo.com/root/releases/release022105.htm">Something good from ATP???</a></li></ul>

PIPES...anyway. I thought it was kinda neat actually. I'll decide on it later...figured I'd post it here and drop some info.

vs the much larger inlet of the RS. All they are selling you is a RS wheel cut down to fit the R housing. More "marketing" from ATP.

to compare back and forth with the pics on the ATP site. Only thing I'd have to re-use off the R is the comp housing so I could use the wastegate without hack this housing to fit...it's just easier.
02-22-2005, 09:05 PM
I heard that APR was using a custom made 28rs which is essentially the 28rs compressor in the 28r body.
02-22-2005, 09:06 PM
28/71 in the GT28R housing. Both are still in the throws of tweaking but thus far each looks pretty viable. One of the tranverse guys machined out his GT28R housing for RS guts .. taht too seems to be comng along just fine.
The one real caveat is APR uses a larger and, IMO better, waste gate actuator set up. They also use the larger inlet with a slip connector as opposed to the 28R style inlet ....

with the original wastegate since I use an EBC. I used a transition elbow from the turbo inlet. So it's 3" at the inlet to 2.5". I was able to couple the APR inlet hose to the transition elbow with a piece of al between them. So I have the RS on the car with the APR manifold and high flow cat, the original stage 3 inlet hose with stock MAF housing and the TT injectors that came with my kit. SO for right now, I'm running stage 3 software with 15 psi of boost and everything is cool. It's about where I was powerwise before with the GT28R. When APR releases the injectorss, plumbing and software I need, I'll jump on it.
02-23-2005, 04:09 AM
the longitudnal kit will use the traditional RS compressor housing.
02-23-2005, 04:10 AM
i.e. run the APR software for now like I do, I think it's best to keep the same inlet plumbing and MAF ID as standard stage 3 runs.
02-23-2005, 12:36 PM
Way more than what the R and the RS compressors can ever flow.
02-23-2005, 03:15 PM
intake setup anyways, rather than hacking 2 turbos for the desired results I'm gonna follow Rays route and bolt up a standard 28RS (or as yippers suggested a 2871R-but whats the difference between a std 28RS and a 2871r???)
Plus it seems a 28RS bolts up in place of the APR turbo anyways, just gotta do my own intake plumbing (cake).
02-23-2005, 04:17 PM
02-23-2005, 04:18 PM
similar compressor housing.
02-23-2005, 05:09 PM
gt2871R....hell..if it fits, and gets a little more power, I won't care that I have to make my own intake setup, it'll be kinda fun actually. I remember when I bought this car 2 1/2 yrs ago I NEVER intended for it to get this far...kinda funny how things happen.
02-23-2005, 09:11 PM
upgrade from APR.
But .. as Ray said he can run the spud or a 28/71 with the APR software and the OEM MAF housing (likely up to about the same boost he runs now) while he sorts out the 'rest of his solution'. In addition, there are a couple of folks who've preceded him with the same hardware/software upgrade path that would be willing to share info I expect.
02-23-2005, 09:13 PM
Would be nice to see how they do it to give us some ideas..
02-24-2005, 12:13 AM
by the likes of a true publicly released S3+ besides the tuning is close enough to allow for fine tweaking. ray could use lemmiwinks while you ndbw guys will have to be more intuitive and use an S-AFC or split sec fuel timing controller.
personally, i would ditch the stock maf housing in a hurry.
02-24-2005, 02:13 AM
Went right for the big power of 550+, passed on the 400's completly.

02-24-2005, 05:00 AM
for now I'm going to wait and see where things go. I'm happy enough with how the car runs now. My patience is wearing thin with my FMIC for now. I want to deal with that and hopefully when that is worked out, I'll have an APR option to maximize my potato. But yes if I have no other option, some bigger injectors, new plumbing and lemmiwinks will most likely be the route I go.
02-24-2005, 05:01 AM
02-24-2005, 05:03 AM
I was thinking about going this route myself, but I've already lost one motor and 400 hp is probably pushing it for a higher mileage daily driver.
02-24-2005, 06:00 AM
Porting over the programing from that platform to the inline DBW is pretty straight fwd. The only remaining issue would be fitting a modified airbox if one didn't wish to run an intake.

even though it looks small. You mentioned that it's restrictive. Restrictive is a relative term. It might be restrictive for flowing 60lbm/min but not so for the small 28R or RS wheels.
Your turbo doesn't flow that much more considering the size of the housing. With that in mind yours should flow about 50 to 55 lbm/min for the amount of power you're claiming.
Either way, I could care less whatever turbo you ended up skipping over to get to where you are.
02-24-2005, 12:49 PM
02-24-2005, 12:56 PM
No I leave the making "fake" claims to you guys.
02-24-2005, 01:42 PM

it seems we are being neglected as of late. which imo is dumb seeing as the costs of these cars are becoming as low as they are. owners who have paid off their cars or are new owners have more dime to spend on mods (not to mention it brings in a whole new genre of asshats with more money then sense). at least from a demand standpoint this market is really just starting to grow. motors are cheaper then ever too so people are more willing to hammer on their cars. i remember back in the days like 4 years ago when people would wonder if running more then 14 psi would blow their motors. and warranty lol.....

3 years to get it right so I passed :)
02-25-2005, 04:42 PM
and another RS4 bumper i am not in a hurry as i have backups. just something different that will look pretty sleeper when i am done. i also have an S4 rear already painted and am in the process of acquiring some S4 side that will need to be painted.
he can machine out a 28R comp housing and make it fit on a 2871R, put the proper wastegate actuator on it and build a bracket to mount it in the right area (in relation to how a 28R is setup in the stg3 kit) and ceramic coat the hotside for 1195 shipped. Sounds good. game on!

I'm gonna have to home brew my own intake system as the SW requires a 3" maf. my intake is gonna transition from 3" to 2.5 as it goes into the turbo. As long as it's smooth I shouldn't have any issues. This should be interesting.
02-26-2005, 05:58 PM
anything else out there short of the duh which i would say is the same thing with more bling (ie clamps and what not)

03-01-2005, 05:46 PM
and I lost 2hp. just couldn't keep up anymore..I'll dyno again this spring w/o race gas and see what I pull on my current street setup

I cleaned it out with break cleaner best I could. I actually had a few ounces of oil come out of the the lower endtank when I removed the lower inlet hose. I don't really have the patience to get the cross pipe clean...a new FMIC would be ideal right now.
03-02-2005, 08:01 PM
or paperweight? sorry that was wrong....

I sent the APR wastegate actuator from the last one to another stage 3 guy to use on his 2871R attemp with APR hardware. I will clean the 28R up and use it as a decoration ;>P
