GT-5L race engine

CR Machine's GT-5L engine is like no other engine on the market. It features a precision balanced crankshaft (not stock factory balance). This engine has been completely disassembled and has features you won't find in any other engine. Crankshaft geometry is unique, offering higher performance than an ordinary GT-5 engine. The engine is accurately assembled and the crankshaft is precisely shimmed to the crankcase. Excellent cylinder porting and CR Machine's special long spigot intake system gives this engine a very wide powerband. The GT-5L engine is only available with the 19.5mm PHBG carburetor.

If a highly advanced exhaust sytem and race fuel of at least 100 octane is used, then the 5.5cc new competition or the 6.0cc head would be the best match. 

If 91 octance pump gas will be used with this engine, then choose a lower compression head. The 6.0cc model will be good when moderately advanced exhaust and 19mm carburetor is used. However, if a highly advanced pipe is connected to this engine, then you should go with the 7.0 cc head. The PHBG style spigot mount carburetor included with the engine has been set up with correct idle and main jets for average conditions. Extra main jets are also included for fine tuning to correct for the elevation that the engine will operate in. Also comes with high quality foam air filter.
