Fuel Regulator

[tashwR33]

I am new to skylines and looking to upgrade my fuel reg and my R33 has two is this normal? If so do I need to upgrade both or can I change to one?

Thanks

The second 'reg' is a fuel dampener.

There is no point changing the regulator unless you have maxed out the injectors and are too cheap to buy larger ones.

If you're new to turbos you will find heaps of guys telling you what to do - some informed and some completely clueless. Try to spend some time reading through the forced induction section and the sticky on RB25 turbo upgrades to get some idea of where to go and beware! Modifying starts with a few hundred dollars and ends up consuming thousands!!

Best first step is a 3in turbo back exhaust.

Cheaper is a high flow panel for your stock filter box (if you haven't already got a pod)

Also cheap is a modest increase in boost to 10 psi (free or cheap T)

You don't need a new fuel reg or bov unless either is patently faulty.

If you come across an unfamiliar term or want to know how something works Google is your friend!
