200SX Question

[Harps]

Apologies if its a stupid question, but I know less about 200's than I do about Supra's.

If you install a decat pipe do you need to fit a Restrictor Ring to stop it overboosting?

Cheers in advance

A good forum for the 200SX's is the owners club

Nope - unless your running a really free flowing exhaust, and depending on how and iff your controlling your boost.

 

If your running standard boost, no problem, decat and forget.

 

If your running anything near a bar, you may hit boost cut on cold day or if you suddenly floor it, due to less resistance in the exhaust it can boost spike.

 

Even then you dont need a ring, just wind the boost down a touch.

 

Whats the spec of the sx? s13/14/a? full decat or just one?

Cheers guys, its for a friend of mine who's just fitted a boost gauge - its boosting up to 20psi. The problem may well be with the fitting of the gauge, but I'll see if I can get a bit more info. Though the boost cut is a very good suggestion, I'd not thought of that (hardly surprising! )

 

The 200 in question is a S14a

If hes hitting 20 psi:

 

1) its going to go bang uness hes done a lot of work to it

 

or

 

2) his boost gauge is lieing - boost cut is reliably on the nose of 1 bar (14psi) no way a standard car could make 20psi.
