We have had a customer car here with the ATP 3037S and .82 ar exhaust housing. The mods were 264/272 cams, Buschur FMIC, 3" TB and our SAFC tuning (EMS was next).

The turbo hit hard and fast, and had full spool by late 3000rpm. It pulled all the way to 7800rpm and kept wanting to pull. IMO, on pump gas, the car hauled ***, and was a great turbo. I would highly recommend it for drag, autox or road racing.

IMO, the 3071 is not worth the upgrade, some would argue otherwise, but I do not believe it is a worthy upgrade over the already good stock turbo, especially if you have the 10.5.

If anyone has any questions about the ATP, Buschur or AMS kits, I can help answer, since we have had experience with all of them on customer cars.

I dont agree at all with the comment that the stock turbo will not be reliable at higher boost levels. We have been putting big, small and EVO III 16Gs on DSMS for YEARS now and those turbo are run into the GROUND for boost. If you think EVO owners are hard on there cars talk to a DSM owner. Mitsubishi stock turbos are some of the toughest around. Will you make more power on a larger Garrett turbo? well of course but saying that the stock evo VIII turbo will not last at those boost levels is not only silly but its just plain wrong. what do you think mitsubishi used in the Rally events?? Mitsu turbo's! and you cant put a car through more abuse then a WRC event.

I do that myself on race gas..... but I acknowledge the fact that I am destroying the stock turbo doing this. That is why I have the boost control through the AEM EMS set up on a toggle switch to give me 14 psi (about 315 HP at the wheels) most of the time and only bump it up to 20 psi ( about 375 HP at the wheels) when I am in the mood to tear up the road

I have already destroyed 1 stock turbo.... (upgraded to TME titanium with 10.5 housing at that time) but I think it was a combination of overspinning the living crap out of it and compressor surge from having to hard a spring in my Tial BOV.... but the stock turbo's are defenitly NOT indestructable. If this turbo gives up the ghost, and I have some money built up I will get a major turbo upgrade. If I am broke and this turbo gives up on me I will get it rebuilt.

im saying the stock turbo which is a mitsubishi turbo is made by the same guys that supply the turbos for the mitsu rally car. if you allready went through one turbo I would look into another inherent problem. we have anywhere from 6-10 evos in and out of here in a day and only ONE has failed and that was due to the motor failing. I have NEVER seen an EVO III 16G fail of it own doing with less then 100,000 miles on it. remember the EVO VIII wasnt the first to get the 4G63 and a turbo here in the sates. pointing a finger at a Mitsubishi factory turbo and saying its unreliable when run hard is just plain silly

no one is pointing any fingers. What we are saying here is logic. I dont think in fact i am positive that no EVO on US soil has 100K miles with stock turbo boosting 26 PSI, Have you seen one? until then you cant compare your DSM to an EVO because they are different.

You are saying that the stock turbo will be just fine even when boosting 26 psi right?

here we go again. I will admit that the DSM and EVO are different cars but there differences are not as far off as you think. I have first Generation eclipses and Talons in here that are being ridden like a women at the bunny ranch and are starting to go out after 100,000 miles. These are cars that are not properly maintained...and generally beat to hell. and lets not forget this is an ancient turbo. Technology has progressed quite a bit since then. The early evo 16Gs were as close to bulletproof as you can get on a turbo. They got better every year. Are going to sit here and tell me that for some reason on the EVO VII's and VIII's mitsubishi decided to slack off and put a weaker more unreliable turbo in the powerplant. LOL this is deffinetly an argument I have never come across

Well TAD motorsports, who has been building EVO's for rally use for many, many years use the stock turbo that the EVO's come with. They run almost 30psi at rally's. The turbo's last and last, and they see way more abuse than any street car will see. Show me some solid proof of failures related to high boost.

The ATP rear housing is a big POS. The kit is cheap and produces power but it is a waste of money for a poor producing turbo kit. Since you mentioned price RnR and Buschur both have turbo kits for under $2500 that will out perform that ATP kit all day. With the ATP kit you are screwed because you keep the stock manifold and that limits your options for the future. If you buy the Buschur or RnR type of setup at least you can upgrade to a bigger turbo if you want more power down the road. You can sell the t3t4 from the RnR kit an upgrade to a garret GT turbo if you wish but at least you can get a good turbo since you have a new manifold. The same thing is true for the Buschur kit. If you don't want to upgrade to a bigger buschur turbo you can try one of the many DSM hybrids that a are available since the Buschur manifold uses a DSM flange. I know you can upgrade the ATP but it will still be using the POS rear housing. Don't waste your money on a very bad designed kit.
