I am running a B18 LS bottom end from JG Engine Dynamics thats bored to 84mm, has been sleeved, and has a 23 tooth water pump from a GSR ($2,800 for the short block) a built B16 head with Skunk2 valvetrain, cams, and cam gears, the bowls have all been matched for volume ($2,000) Skunk2 intake manifold, and throttle body, AEM fuel rail, AEM fuel filter, AEM fuel pressure regulator, RC 1000cc injectors, driveshaft shop 1000hp axles, ACT clutch and flywheel, Cusco LSD, AEM EMS, Greddy Profec E-01 boost controller, and turbo timer, Cometic head gasket, ARP studs for the head, and manifolds, Golden Eagle dowel rods for the head, and a nice stage 3 turbo kit from Full-Race. My car has a full interior, A/C, power steering, a full stereo system, and street tires. It ran a best time of 9.87 @ 148 mph in the 1/4 mile. This was on 25 PSI of boost and 93 Octane gas. It is driven daily on 15 PSI and puts down 402 HP at the wheels, and on 25 PSI it puts out around 700 HP. Yes it is a DAILY DRIVER. It was built correctly and professionally, no corners were cut. Like the water pump the LS has a 19 tooth one and the GSR has a 23 tooth one. For a all motor setup the 19 tooth one is fine, but once you get to higher RPM's it can't keep up with the needs of water and actually can create bubbles in the coolant flow and destroy a block. The 23 tooth one eliminates this because it turns faster and although it keeps your engine a little cooler than normal at "normal" driving it will save it when "having fun" little stuff like this is usually what people overlook when building purpose built engines. Definatly do some research before considering it, and if turboing it you will have to do a little more work than going naturally aspirated with a LS/VTEC.
