Intercooler piping size

[gtben123]

Need to no the size of the pipe that goes in to throttle body

 

[AdamB]

Any size you want. Would opt for the same size as the throttle body, 55mm iirc. Depends on engine spec as well.

2" is standard, will also flow more than you think.
Any bigger and you will get more lag

so me buying 2.5 pipe was st00pid?

 

[Tercel]

If you have a FMIC it's not a bad idea to go a little bigger than stock because the longer run of pipe creates flow resistance.

Omikron - Depends what you want, outright horsepower or response.

Tercel - Agree to a certain extent but the bigger the O/D the slower the flow.

I've always thought that 2" is the best because it won't lag and 2.5 will create a massive lag given that everything else is stock except the inter cooler of course, is't that right?
