Spoon does have nice quality products but their intention is to produce replacement parts for oem and circuit racing. A lot of their parts are engineered to produce hp figures in the midrange. I would not buy a spoon crate motor/longblock. You should consider actually how much dollar you end up paying for one hp. You have to decide on whether you are going NA or FI, then we can make a recommendation based on your car and year it is along with the most hp producing parts.
If you are going NA, then I would recommend a ITR complete swap as a drop in and never touch your motor again. Since you do drive an Teggy, then I would be looking for more tq to pull more of that weight out of the hole. It also depends if you want to just drag this ride, or Autox.
To put it another way, I would only consider buying a couple parts from spoon such as suspension components, wires, sideviews, and CF components such as their rear wing and front lip.
