To those with decent boosted builds that have been running for a while w/no major issues... what eng gap upper/lower ring are you guys using? I have a customer's car at my house that made 397whp, but a shop gapped & assembled bottom end last time (idk the gap since almost every ring was broken when I pulled the motor apart). This is his first honda but his 3rd build n he's getting very discouraged so I'm trying to keep him in the honda scene, I've hooked him up massively on parts/labor but I'm jus trying to avoid any issues down the road so any input would be appreciated. The formulas online for end-gap are a lil vague so I was hoping to get a lil more specific insight here as to what ppl are actually running.
here's the main setup. Also, its his DD, mainly freeway about 50-75mi/day ...

2000 Ls
84.5mm Golden Eagle sleeved B20b block
Wiseco 9.0:1 turbo pistons
Golden Eagle H-Rods
Cometic head gasket
Gs-R head Mild P&P
Turbonetics t4
ARP head studs
Skunk2 Stg2 cams
RC-1,000cc injectors

tune is Chrome but after break-in it will b goin to Bisimoto for an S300 & retune
(Ty ahead of time for reading/posting)

 

Didnt the pistons come with a paper to figure piston ring gap? Might want to call wiseco and ask

 

they give a formula but like i had mentioned, it's pretty vague.
Application, Top Ring & 2nd Ring
"Dirt/Atv/Snow/PWC .0040/.0050
High Performance Street/Strip .0045/.0055
Street Moderate Turbo/Nitrous .0050/.0055
Late Model Stock .0050/.0055
Circle Track/Drag Race .0055/.0060
Blown Race Only .0065/.0070
Nitrous Race Only" .0070/.0075

Idk, I'd probably say hi-perf street strip or maybe Street moderate since i doubt it'll be tracked ... not exactly sure which tho & Im not sure how they come up with each classification... :/
