Setup:

B16a/Y1 with JE SRP 10.5:1, 70mm throttle, DPR p/p type r intake, Alaniz Technologies p/p head with type r valves and skunk stage 1 cams, AnR 4-1 header with 2.5 collector and exhaust.

The engine is torqueless in the lower RPMs but screams after 5k. I've been told I'm losing velocity and scavenging.

Any opinions?

Thanks!

 

to me the 2 1/2" is too much..try downgrading a bit from their and see what happens

 

Should I go down a quarter or half inch?

 

you have a b16
no matter WHAT you do, you are not going to have mugh low end.

2.5 is ok IMO

For FI IMO.

 

thats 3" for fi hehe

2.25 would be fine too

 

Good god. 3" for a B16? Why not put a diesel turbo up on that to spool

 

for a BOOSTED b16

hey bigger the exhaust less lag on the turbo
