The best thing to do, if you really want to get a loan, is get a personal loan.

If its a B18C than it's JDM and can be one of two engines

GSR or Type-R (both being JDM).

The GSR comes with 180hp and 129 lbs/tq
The Type-R has 200hp and 137 lbs/tq

On both engines you have to consideer wether you will go NA or... what was the other one (Turbo, SC, or Nitrous), simply because of the other specs on the engine
