I am getting ready to do a build...i will be posting new thread soon

 

I got the ATS 093 aftermarket kit and it came with the larger housing and 3" downpipe that slips into the housing.
The picture in the install manual for the 093 kit shows the large housing with slip in downpipe.

Heres is my guess on why Ford neutered the ATS design. To use the larger 3" downpipe, you have to flatten the cab firewall seam and possibly massage the firewall some as well. Thats a bit of a pain for installing the turbo, but not a big deal when you're going through the rest of the work installing the turbo. But for Ford to have to install them in the factory would mean changing the cab design which would be a HUGE cost (new dies for the body panels, changes in assembly tooling, etc....) That wasn't worth it for them knowing the ATS turbo was a short term upgrade with the Powerstroke engine coming to market so soon and phasing out the IDI engine at the same time. So Ford's beancounters said change the downpipe to fit the current body. The v-band clamp was probably the better option over the slip fit pipe as it would be less likely to fall out or leak, which would be a bad thing on a production vehicle, even though it would add a small cost to production.

At least thats my theory on it.

When you look at ATS, they are about performance and having the end user massage the firewall was a no-brainer. They knew the turbo system they designed needed the larger airflow, but they were probably happy taking the money from Ford for the neutered stock turbo kits. Then even happier to offer the "upgrade" kit to people aftermarket and get more money fixing the change.

 

ah ok.thanks for verifying.not that im in the market for a used kit.just curious.
they did the same thing with the 94-97 PSD trucks too.crushed dp's.
i see they're still up to these tricks with a crushed intercooler pipe on the 6.4l trucks.i looked online and of course the arftermarket is right there to run a full non crushed pipe for those too.
i wonder if they're still doing these type of things at all on the current 6.7l's.

 

Does anyone know what mounting flange the 088 uses?

 

I might be wrong but i believe they are both t3 mounts

 

The 088 is an odd duck. It does not have an up pipe mounting flange. Rather the exhaust housing is a unique one piece casting that the up pipe and down pipe mate to via slip fit joints.

 

Figures,I always end up with odd ball stuff lol,I bought a truck for the turbo mostly because it was headed to the scrap yard but the more I think about I'm thinking on going with an R&D kit

 

088 and 093 are the same turbo. Only difference is a .87 T3 wastegated housing on the 093, where as the 088 has a 1 or 1.1 proprietary housing. Both are good kits, both have ****ty air filter needing replaced with a real one. Theyre decent up to 20ish psi (maxxed stocker / 90cc pump) but past that should be replaced with something that flows a litte more.

 

Every ATS version I have seen was 3", which makes sense because being aftermarket, your installing yourself, you can beat the seam over on the cab with no issue. However, Ford wasn't going to do that at the factory, so they needed a special housing and downpipe to clear the cab. The 3" outlet on the 093 wasn't an "upgrade", Ford just used a different downpipe and elbow to clear the cab, it was the "downgrade" from the kit as ATS produced it...

 

Whoops, missed the second page....... This....

 

Racin, you've certainly seen more turbos than I have, so I'm glad our thoughts match on the issue.
