Speedo reads half of what im doing

[wowzers9930]

Okay so someone told me that I need to re calibrate my speedo. I have done some searching for the past 2 hours and I cant figure out the best/cheapest ways of getting the speedo to read correctly. I figured out my tachometer issue and going to order http://rawbrokerage.com/BBT-RB-Tachomet ... ometer.htm

But I would appreciate the help with my speedo issue, please and thanks

Also, On a side note would anyone want to recommend a good turbo inlet gasket and downpipe gasket? Perferibly something thick and going to hold up

OEM gaskets are great

Okay well they are prolly quite expensive, are there any online alternatives?

JDM speedo, can be calibrated with the pot on the back.

I thought I read somewhere that the z32 sensor will get your speedo reading correctly. I have the same issue and was about to fix it but the miles only go up 1/2 as well so I decided to leave it alone lol. Mine reads exactly half at any speed so its not an issue.
