This housing is a great upgrade over the very laggy factory 1.15 AR exhaust turbine housing. Smaller AR housings result in much quicker spool up of the turbo whereas the stock larger 1.15 spools much slower.
This housing is also great for towing in that it will help give you slightly more boost with towing at highway speeds too. We also offer the 1.0 AR housing for those with slightly larger than stock injectors that want a combination of decent spool and still have a bit more top end power. We recommend the .84 for stock injectors and the 1.0 for 160cc or smaller injectors. For anyone running larger injectors we recommend upgrading to the KC Turbo KC-TP38R.
