MHI TD03LL1 Bolt-On Turbo Upgrade - Honda Civic (FC / FK7) 1.5T
The MHI 49S31-A0100 is a bolt-on upgrade turbo for the 1.5-litre turbo L15B7 in the 10th-generation Honda Civic. It is built by Mitsubishi Heavy Industries, the company that supplies Honda's factory turbo, and swaps the stock wheels for a billet HR2 compressor wheel and a larger turbine wheel, so the engine can move more air at higher boost while keeping the factory mounting.
Note: Suits the 1.5T L15B7 Civic hatch (FK7) and sedan (FC). A custom ECU tune is required, and MHI recommends Hondata FlashPro and 10W-40 engine oil. MHI sells this turbo for off-road competition use only. Check your car's original turbo before ordering. Installation by a professional is recommended.
