A compression test is simple to learn and only requires a few basic tools. From a mechanical perspective, you will need to know how to properly remove the spark plugs on the vehicle or equipment you are testing and properly disable the ignition system and fuel system, the latter if the vehicle is fuel injected. For carbureted engines, you can choose to disable the fuel supply . you will need a compression check to make sure your fine befor you think of anything big. even if you don't want to spend alot of money you can buy slightly used turbo setups for around 00 with decent equipment. also you can find build blocks for around 00. so for 00 you can have a car with around 400whp assuming you know what too look for in used .

I'd suggest keeping the ls block and doing a high compression ls/vtec.. to be honest.. you would really rev a ls/vtec just as high as a gsr..and you keep realible.. if u dont plan on sleeving a b20..u lose alot of "self insurence" because the sleeves are already paper thin and reving a motor high will crack them.. ls/vtec would be the more .
