mod list and questions for EVO316G setup
Hi guys, doing an FP EVO316G setup here, going to be surgeline protuned via APv2. Car is getting new timing belt and tensioner done first (103,000 miles but well maintained), then FP turbo, DW 650cc injectors, BIG TMIC, Short ram intake, walbro FP, EGT, AFR gauges. Already have megan racing catless DP, catless UP, SRS catless 3" exhaust, boost gauge, oil pressure gauge, APV2 with stage 2 map tweaked by myself, and a prodrive 3 port EBCS.
1) Is it required to get new fuel rails?
2) My stock BPV that i have on now won't hold the 20+psi that surgeline will be shooting for. I also have a GFB hybrid but have problems with compressor surge with low boost which is annoying as hell. I'm thinking of trying an HKS SSQV due to its different type of piston inside versus the GFB spring/piston setup. I've heard of the sequential type BOV giving quicker response time when blowing off. Is there any truth to this?
3) For streetability, what WG actuator spring should i order the turbo with? It comes with a 14psi spring, with an option of i think an 8-9psi spring.
4) Anything else that im forgetting thats really significant?
