Optional T51R Mod:
-
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 OEM Borg Warner S200 housings in divided T4 are quite unique. Even though they have a T4 Divided footprint, their volute size matches a T3 volute, which is significantly smaller in size and restricted in airflow over a T4 volute. AGP developed their own performance engineered housing for the S200 turbine that is a T4 divided footprint and has the proper T4 sized volute. AGP prides themselves on developing turbine housing options to fit the needs of today’s enthusiasts no matter their build. Plainly said, if you want a twin scroll T4, look no further than AGP’s .84 A/R or 1.00 A/R for the S200 sx, sxe, and sxr.
The bearing housings are not water-cooled and have a 1/4"NPT oil inlet. The oil drain is the standard T3-T4 with M8x1.25 threads. Lines and fittings are all available here. Flanges and gaskets are available here.

Amazing srt4 turbo
With a super minimal mod list on pump e85. Stock sealed long block srt4 neon made a little over 500whp at 30psi. Full boost right at the 37-3800 mark with the .63 housing.

S257sxe 1.15 turbine housing
No complaints with AGP, good shipping time and didn't come damaged. Little disappointed in the internal volute surface. Carbide can smooth out most. Performs very nice so far on my tractor.

S257SXE
I purchased this turbo about 7 years after I rebuild my engine. I run it on a 7.3 idi in an 85 F250. Over the years I have tried many turbos ranging from a t04b to an s366. I settled on an s360 for about 3 years, but it was notably laggy, and I could only ever get 13-15 psi from it and egt would be great while cruising, but it would get fairly warm in any sort of load condition.
With this S257SXE I can easily hit 20 psi even in lower rpm, and the lag is non existent. Egt are pretty much never an issue with this setup. I would reccomend it for anyone looking for a turbo for one of these engines in a stock to mildly modified setup. -

S257
Shipping was quick and product was as described. Customer service was excellent and polite when they notified me that the original turbo I had ordered was no longer available and offered me this as an alternative. Turbo itself is of good quality and works perfectly.
