D14A1 Dual carbs.

Post by narwass »

Hello,
Anyone with some info about tuning the dual carbs on this motor?
Current mods:
Velocity stacks on each carb (3d printed) with foam filters (socks) from aliexspress.
Exhaust manifold 4 into 1 and im building new exhaust with pipe diameter 60mm inside.
The chassis is civic 4 gen.
The hydraulic system is removed.The aux belt balancer is with weight of 720-730 grams (its oem).Only the alternator is there.
Car weight is 840kg last weight and aiming to under 800.
Looking for carb mods like:
How to adjust acceleration pump of the carbs.
I know about cutting springs to increase fuel at the top end.
Any proven mods or info is welcome. :)
