You love the durability, availability, and affordability of the Borg Warner S300sx series of turbos, however those factory John Deere housings make them a little bit more difficult to install and get to spool up. AGP Turbo has the answer by casting a correct .80 A/R, or 14cm2 for you Cummins guys, to fit these S300sx turbos with a divided T3 inlet and the 4.0" HX40 style outlet. Just bolt on to your 2nd Gen style manifold with an HX40 downpipe, and you win. Well, technically we win too.

We offer standard S300 clamp plates and bolts to mount your supercore to the turbine housing. (Note: Our housings use the standard S300 bolt pattern, so if you already have clamp plates and bolts, you do not need to purchase another set.)
We offer a Billet Stainless V Band Outlet Kit to weld to your 3.5" or 4" Downpipe. Select that kit in the options above, or buy them separately here.
Ceramic coating is available. While the ceramic coating is definitely not needed, it does help reduce underhood temperatures. Please note that ceramic coating is done after the order is placed, so please allow extra time to get the part(s) coated.

I bought this and converted back to a T3 on my box stock S363. This one spools so much faster and kept my EGTs in check. Definitely recommended
So I received my housing within 6 days of my purchase which is about what I expected and as I was comparing it to my .88a/r housing on my s363sx I noticed the ag housing was a much better looking piece in terms of casting and machine work. However as I was trying to install it, it was not wanting to slide on. I brought out the dial calipers and found that it was a tighter fit and it had a slight flat spot. So with a little emory cloth I made a couple passes on the lip and touched up the flat spot. It then slipped into place but just a tad more snug then the .88. Once I fired it up I immediately noticed it had a spooling whistle which it never had at idle before. Through the test drive the tone was amazing! I had never heard any spoolup sounds until it was really pushed but now its always audible and the low and midrange power is a night and day difference with much better driving manners. Top end power is still about the same but I only bought it to address my soso low and midrange power. All in all in very pleased and would highly recommend this to anyone running a bw "box turbo".
