RE: Need help identifying car...
the engine is exactly as it reads. its an hpi nitrostar .12 first gen motor (it has the squareish heatsink) if it still has good compression and runs ok you might as well use it, but soon youll need a new one. for such a big car you should look at a .18 or .15engine
unfortuneately, the engine is so old i cant even give you a link to it >.<
