What makes the AGP Z400 series different from Borg Warner's S400 line? Even though AGP is a Borg Warner distributor, we've found the weak links and decided to perfect on that. In order to have the most durable turbo of this frame, these turbos use a 360 Degree race bearing system that provides superior rigidity and added cooling to the thrust bearing so it can support ultra high boost applications. The Z400 also comes with an O Ring seal on the compressor housing. This eliminates the common leaks found on S400 turbos between the seal plate and the compressor housing.
Optional T51R Mod is where we plug and then CNC machine the inlet of the compressor housing to amplify the turbo whine and whistle. Keep in mind this modification is done after the order is placed and typically ads a week or two before the order is shipped. However, sometimes it can take longer and maybe even up to 4 weeks. If you have ordered other finishing options like ceramic or polishing, it may add additional time on top of the typical 2-3 weeks before your order ships. Because of the labor intensive work and machine time needed, there can be delays beyond what we quote. We do take special care to every order to prepare for shipping and want to make sure you get the highest quality parts and service. We are confident that the quality you receive is worth the wait. We appreciate your patience while we work.
The Race Journal Bearing housings are not water cooled and have a 1/4” NPT oil inlet, and Standard S400 oil drain with 3/8-16 threads. Lines and fittings are all available here. Flanges and gaskets are available here.

12.7 Detroit
Changed from a BW 171702 to a Z476. Much better spool up, and overall power. Less peddle is needed to pull hills. It does some huffin and puffin. EGTs are down across the RPM range as well. It’s a dam good turbski for a big truck. I’ve seen 48psi at partial throttle and PP Box on level 2. Seems like it’ll do more, but I don’t want to send a piston into orbit. Gotta drive like you have a brain.
