*hangs head and disappointment* I did not mean motors in general funny dude got back to my previous post Turbo adds weight intercooler adds weight your miscellaneous eBay and Freddy bolt on's adds weight so therefore you SR ENTIRE swap adds up to more pounds than a regular ole ka haha so if I was in a box truck that was weighed the same as a s chassis with a sr20det the areo wouldn't effect my speed? Also I'm not talking *shit* I'm just stating a few flaws in your post if I was talking *shit* I'd say something like "man 1slowsilvia more like one slow ass OP" so if you have any other words needed fine tuned let me break it down to something you apparently understand ka lighter than SR ENTIRE swap with your Freddy your eBay ect ect b.s SR short block lighter than ka short block simple as pie bro oh and thought you might like to read this Aerodynamics - Wikipedia, the free encyclopedia
