throttle body upgrade for 2002 Accord EX 2.3L 4cyl

[jmal1919]

Does anybody know if a upgrade to a BBK throttle body is worth it for performance. Also, are any other modifications necessary to do so?


Any advice would be nice.

for most street setups the overbore TB isn't worth the $$, especially for $300-400 for a straight through, true overbored TB.
not just a tapered one.

if going all out N/A then in the end it'll be worth it. a basic N/A setup will do fine without a larger TB. even basic F/I setups will use the stock 60-62mm TB's to match up to the chargepipe.

would I have to make any other tweeks to the engine if I do up the TB?

you would want to match the plenum inlet diameter with the TB diameter so the flow is nice and smooth without restrictions or a bottleneck.
