intercooler dump pipe diameter?

[tomgt106]

Hi guys can someone tell me the dump pipe diameter? Looking at a hks bov and want to know the size..the bov outlet is 20mm..

Is this the same as the starlet?

Cheers in advance

By 'intercooler dump pipe' you mean the pipe between the intake and intercooler, where the stock BOV is located? Not the acutal turbo exhaust dump pipe?

The stock intercooler itself has 51mm pipe for both in and out. Then the throttle body is slightly larger at 65mm from memory.

So you need a 51mm pipe with the HKS BOV 20mm dump.
