We all know honda will be coming back with an Si coupe(I have no idea why, I thought the 02-05 Si hatchback was sweet besides the engine). But because we are Americans and we love coupes and the 99-00 Si coupe sold so well, The new si will return as a coupe. Now what engine to put in it? I figure Honda/Acura will keep the RSX platform for many more years to come with just minor enhancements because it is selling so well, exactly like the integra(1994-2001). But you know how Honda doesnt want to sell a faster civic than the RSX or they will be losing money, and that is why they wont put in a RSX type S engine in the new SI coupe. Well, I noticed that the new 05 RSX type S has 10 more ponies than the previous 02-04 type S. This was achieved by higher lift cams and longer runners in the intake manifold. SO now the type S is 210 HP. Hmmm...., could this mean that Honda will put the older k20 type S motor with 200 HP in the new Si??? On paper the rsx will seem faster because of the 10 extra horses and along with the luxory of leather and stuff should keep buyers interested in buying the RSX over the Civic SI, but also because of the power increase and potential of the REAL k20 motor, buyers who quite cant afford the RSX will buy the Si instead of going for an SRT,golf,celica GTS. In the end, Honda doesnt lose sales and money. Just a theory I thought I would share with ya.
