Right so im building an EG k20 (some of you may know) and im stuck about which parts to choose. The likes of Manifold and exhaust etc. Ive been looking at the skunk2 k swap manifold and the 3" skunk2 RR exhaust. Everyone knows they can be pricey enough. Is there much difference in gains from a 2.5 to a 3" exhaust? Is there any other manifolds/exhausts out there that are giving better gains than the ones ive mention? Maybe even cheaper ones that give the same gains? Also which fuel rail, cams etc etc. Im just trying to source out the best parts and best value for money. I know theres not going to be loads of k swaps on here but i know theres a fair few to maybe answer some of my questions. Ive posted this on k20A.org too, incase anyone just thinks im posting on an ek9 forum.
Thanks, Jack!
3" will provide more gains, so will a 2.5". If you have a more aggressive build, higher compression, cams, port polish, for example, you may get a tad more out by using a 3"...not a night and day difference tho. Louder too...
