This is the exhaust/turbine housing only. It's a T3 (T31) inlet (exhaust manifold side) with 2.5" 5 bolt exit. (downpipe side). Direct bolt on & replaces/upgrades your existing housing.
Installing & replacing your turbine housing is very simple. Once the turbo is removed from the car, the new housing is installed by simply removing the (6) 1/2" mounting bolts holding the turbine housing to the center cartridge. The old housing then slips right off & the new housing goes back on in the reverse order. Some applications do not require that the whole turbo even be removed from the car depending on available space & leverage. This is a 1 out of 10 in difficulty.
Turbine housings are often changed or replaced for various reasons such as:
- To allow the turbo to be used with a new application, exhaust manifold or downpipe.
- To obtain a more desirable A/R size for your application.
