David,
So, you are suggesting that people only go with the Stage 3 (if we already have an upgraded fuel pump) if we are sticking with the stock turbo? Would you suggest the 680 cc injectors if we are doing occasional autocross or road-racing? On a related note, do you recommend your deluxe (with the lower IC piping) or the standard intercooler for a car that's mostly for street use with an occasional autocross or road-racing track day?
Thanks.

magancore wires
I purchased the magancore wires from you guys based on your test. I/we all really appreciate all the testing and communicating of results. It is not only very informative, but very entertaining to say the least.
Anyway, my questions is...are these wires supposed to fit as snug as the stock ones?
The boot does not seal up against the valve cover where the spark plug hole is (as the stock ones do).
Car runs fine, but just wondering if this is the way they fit.
Thanks in advance,
Scott

So many of the tests I have already done, like comparing a 2.5 cat to a 2.5 offroad pipe are only in my notes now. I don't know if that was what you wanted to post or if the actual staged upgrades.
Now for some juice.
Pulled the car yesterday afternoon. The temps are over 20 degrees F hotter in the building today than last time. Ohio's weather sucks.
Using a non-corrected actual HP pull changing intercoolers in 20+ hotter weather did nothing although spool up was slightly better with the deluxe core, still would not make more peak hp. Now in the SAE corrected mode, which is what most of you want to see and have requested that, the Deluxe FMIC core made more HP from around 3500 up. Looks like around 6-8 whp. Personally and honestly, I don't believe it.
Next test and I was only doing this one because they were on my work bench to test and I was tired of moving them, plug wires.
For goodness sakes, the car only has two short wires on them. In the DSM's of the past plug wires have proven to be a big PITA. Get a customer to call here and tell you what is wrong with his car. First thing you ask is what plug wires do you run and what spark plugs. If they answer anything but NGK or Magnacore wires or if they run Platinum plugs then you have them change those first. Usually never hear back.
My RS has only about 2500 miles on it. It also has about 230 dyno runs on it right now. I pulled the two plug wires off and replaced them with the Magnacore 8.5 mm wires we stock, but have only sold a set or two of. You would think on a new car it wouldn't make a difference. Wrong. The HP went up a few 3-4 whp in parts of the curve. The really amazing thing was how much smoother the curve was. The plug wires got rid of some small dips I had here and there in the curve. These wires, I have to say are a must have part even on a new EVO, atleast when the HP goes up from stock they are. I'm very impressed. These two wires are $55. I am going to have to do some hunting to double check that as it seems a little high for two plug wires, they did make a very nice difference though. I higher mileage EVO would be even larger.

Wow
I just read from page one and it's taken me 3 days to do it but it has taught me a lot. I just got my 03 2 weeks ago and I am still trying to learn a lot, and this turbo stuff is really new to me so I have a lot to learn. I told myself when I got the car that I wasn't going to do anything else to it. 1 because i'm broke from the payments (well worth it though) and 2 because I want it to stay reliable. But after reading all of this and staring at the Buschur site drooling I am wanting to learn how everything works and how to work on the car myself. but for now i'll keep reading and saving my penny's.
Thanks for all the testing and hard work, it's one great way to build a strong customer base.
I might be ordering the plug wires soon and maybe the intake/pipe kit. The previus owner said he put an intake kit on it and it made the car really touchy and had problems with stalling. Whats the deal with that?

In the case of this turbo if you want lightening spool up from a dead stop then get it, port it and install it. Over 4,000 rpm though the clipping picks up the turbo. The way I see it is once you get it to 7000-7500 rpm in 1st and start going through the gear the car will never see anything under about 4600 rpm anyways, so in this case I will take the slight loss under the curve.
Thge 20G will not spool much slower than the stock turbo on the car. The TME is a different ballgame as the spool up is very fast. Top end power should be alot more, over 4,000 rpm, with the 20G.
It is hard for me to guess what the gains from porting would have been on the exhaust parts had I done them before the intake manifold. I'd guess it would be the same.

Dave,
Thanks for the replys and the great info. Your research and testing has definately won my business.
One more question, with the TME turbo, at what rpms did you experience complete spool up, and what amount of boost were you using for the testing? Also, how does the ported TME, and the ported and clipped TME turbos compare to the stock turbo in terms of power above 5000rpm's.
Oh yeah, how much extra do you charge for the porting on the TME if I buy the turbo from you?
_Thanks
revhappy,
I'd like to honestly re-do our Staged upgrades. Problem is it is going to be too confusing for us in the future when you ask a customer what Stage he has. I suggest Stage 3 plus the fuel pump if you already have it. What I might need to do is just change our Stage 4 and include the pump in an earlier Stage, it is probably a good safety measure. I would not suggest the 680's for a stock turbo'd car in any instance unless you are trying to make 25+ psi of boost with it.
The Magancores do not fit as tight but do work very well. I don't think the tight fit is an issue.
Many intakes cause stalling. I believe it to be a disruption of the flow through the MAS. With our original design of intake we had two bends in the pipe. This needed to be tuned to work. With the newest design the pipe only has one bend and has worked out extremely well and requires nothing but bolting it on.
Taylor,
I went and looked at my datalogs, I deleted most of them. On the one I saved of the ti/al clipped wheel the boost hit 20 psi at 4200 rpm. This seems late but looking at the dyno charts it is making much more power there than it did stock. I could look further and see if I can find some "stock" logs and see if it is sooner.
The power gains from the porting seem to help a little bit all over. The biggest gains, and they aren't huge either way come in over about 4500 rpm with the clipping/porting.
The ported and clipped TME turbo from us would be $1080 brand new.

As for the injector and pump questions, look at my last post.
As for the cams, see other posts talking about the same thing.
