Don't wait for months for some shop to rebuild a burnt up stock turbo with 175,000 miles into a big wheel stocker, this is a brand new unit. Its built from scratch to be a big wheel stocker turbo!
For those of you wanting a quick spooling turbo like the factory turbo, and with the possibility of getting up to 330-350 wheel horsepower or more with good tuning and supporting mods, this is a good option!
The factory turbo unit is comprised of two pieces, the cast iron manifold and the turbo cartridge unit. This replaces the turbo cartridge unit completely. It looks like the factory turbo, except it has larger intake and exhaust side wheels. This allows it to move larger volumes of air compared to the factory turbo.
Unbolt your stock turbo, keep the turbine spacer ring, transfer your wastegate and surge valve over to this one, and reinstall.
Stock Turbo compressor wheel specs:
- Inducer - 43.4mm
- Exducer - 56.1mm
Big Wheel Stock compressor wheel specs:
- Inducer - 48.3mm
- Exducer - 68mm
All parts are brand new OEM spec and the rotating assembly is VSR high speed balanced. If we didn't think these were well made, we wouldn't sell them. AGP recommends not exceeding 18psi of boost on these turbos, or any TD04 based turbo, as high shaft speeds will shorten the life of the turbo. However, with that being said, we have seen many SRT-4 owners with Big Wheel Stockers run 22-25 psi reliably. This turbo can make a solid 300whp at around 18psi.
Included is a CHRA with compressor housing and an oil drain gasket. You can use your factory wastegate, or use an upgraded AGP wastegate if you'd like. Transfer over your factory surge valve (or aftermarket noise plate), and your turbine spacer ring. Not installing the spacer ring will result in turbine wheel damage.
90 Day Warranty against manufacturing defects.
We do not require your old turbo in exchange. Buy this, and you are set! Remove the old cartridge, replace it with this and you're done!
We recommend replacing your oil lines when installing a new turbo. If you only buy one, at least buy the oil feed (Search for part number 220229 and select #4) which has many kinks and sharp angles that can build up with sludge. Also replace the gaskets and oil feed fitting. (Search for part number 220229 and select #5)
Please get new oil/water line gaskets when installing this turbo. They are listed at the bottom of this page.
