i have just recently bought a 5 speed sc300 for a project car as well. if u havent already bought the car i would not recommend it for a project car. if you are not willing to spend a bunch of money on it. the problem with the SC's is they are so G@& DA^* heavy you have to either spend the 2grand on carbon fiber doors or have a engine with a very high output to get them to move. the spec on the stock weight of the car is 4,500 pounds. that is as heavy as most SUV's know a days. i am sorry if i am comming across as an @$$ hole but if i would have know that the car was that heavy before i got mine i would have bought something else. but on the plus side it is easy to swap in a 2JZgte and five speed trany. i am going with the 2JZgte with the 6 speed trany it starts out with 320 horse power has a lot of aftermarket support and are bullet proof motors. i hope this helps
