So after a lot of consideration and a lot of jumping back and forth on whether I want to mod the stock engine or which engine I want to swap in, I have come to the conclusion of sticking with the tried and true LS swap. With all the support for a GT86 LS swap it seems like the obvious choice. The one thing I considered a drawback (although it’s a pretty trivial thing to consider a drawback) is the fact that the LS engines do not rev high at all. This led to my discovery of “destroking” a 6.0 block by running a 4.8L crankshaft. I plan to run an LQ4 block, a forged 4.8 crank, forged LS3 rods and pistons, LS3 heads with hollow stem valves and beehive valve springs (to take care of valve float at higher RPM), and a mild LS3 comp cam. I’d like to buy a full LQ4 setup and sell the accessories and wiring harness for a few extra bucks to stick into a bad ass serpentine kit. I plan to run a FAST intake manifold. Wiring I’m hoping to have provided by Sikky but haltech is my back up. Looking at what my stock FA20 with 44k miles on it is worth, this build won’t hurt the wallet too badly. With similar setups, I’m seeing results of a 8-9k redline and nice 480-600hp. Anyone have experience with a similar build? If not, thoughts?
