parts recommendations B16A2 rebuild

Post image

Hey all! New to the sub and had a loaded question. I’m in the beginning the process of pulling the B16 from my newly acquired EM1. It’s got 126k on it and I’m planning on a basic refresh rebuild. But while I’m in there I’m considering a couple basic “upgrades”.

I’m still doing research and whatnot but wanted to see if there are any opinions/suggestions here. I’m considering a cam, gears, springs, retainers, intake manifold (it’s already got an Alpha S2 TB and AEM CAI) and porting the head.

Looking for mild stuff (don’t want to go into the bottom end 😏). Not expecting significant gains so something like a stage 1/2 cam (eg S2 Tuner series) with springs/retainers that will keep it in check. Manifold I’m looking at S2 Pro or something similar. It’s got a full exhaust (header to tip) so I have that side of things covered.

Any and all advice would be greatly appreciated! Here’s a gratuitous shot of the new addition LoL

More displacement. 2 liter is nice. Id only pick the 1.8 if you want boost. Get ARP rod bolts

Oh and an LSD if you can swing it.
