Mitsubishi Shogun/ Pajero LS1 5.7 conversion

[smikas]

Hello All

I have owned a 1997 Mitsubishi Shogun SWB - 3.0 V6 GLS for 10 years. It has covered 98k miles. I will be taking soon for a restoration including full chassis repair and dip.

I am toying with the idea of fitting a high power LS1 5.7 lump with carburettors. I know the engine and mounts will be around Can anyone advise me on the following:

• Who in the UK can do this engine fit and custom make the exhaust?
• If I want around 500bhp & 450 ft torque, what other components must I change?

Thanks
Ian
