R32 Rb20 Vs Cefiro Rb20

[R32FOURDOOR]

Hey hows it going guys,

I was wondering, when seeing my mates cefiro motor it doesnt seem to have a stock blow off valve and when you change gears it flutters. Now if you look at my r32 its got a stock bov and when u change gears you can here the bov going off, no flutter.

You guys probably have your different opinions on this but its about blocking the stock bov on the r32.

Now it comes down to my question if both cars have a the RB20 does that mean, because the cefiro hasnt got a bov the stock turbo is gonna give up quicker? Cos isnt this chopping or fluttering sound bad for ur stock ceramic turbo? If it is alright for the cefiro to not have a bov would it be alright for a r32 to have its bov removed? If any one can shead some light on this area it would be much appreciated.

Didnt nissan put a stock bov on it for a reason, to protect the turbo from that back pressure then causing the flutter sound? why dont cefiros have a bov?

This has had me baffled for quite a while now, what do u guys think then?

Cheers.

ps. sorry about all the questions.

Apparently the ceffy turbo is smaller than the 32 one. Could be the reason..

Ceffys and laurels didnt come with BOV because they are 'luxury' cars. R32 is s sports car so having a BOV would not matter.

At low boost flutter is gonna do shit all. Do a search if ur mate is worried.

I don't think they ran different turbos.. Have heard a31/c33's run at least 1/2 a pound less boost.. Could be part of the reason not to warrant a bov??

I doubt the fact you say they are classed as a "luxury" car is a warrant for not having one. If anything it would be the opposite.

Think of a typical luxury car owner and there shock when they heard the sound of flutter! They would be back at the dealer in no time saying something is wrong.

I have a HR31 GTSR, far from luxury and it has no bov from factory. None of the R31 RB20s had bovs. What years were the ceffy and laurels produced?

Maybe it was an emission thing to fit bovs later on? No BOV would have the breather gasses ( dirty oily air) venting to atmo through the filter.
