Bov's & Gtr Intake On Gts

[RBceffy25]

Ok firstly I will apologise for starting the ten millionth thread on either of these issues. However, it seems it is fairly difficult to find straight answers on these questions.

I feel these topics really need straight, proven answers from ppl who have actually had hands on, real world experience with these issues, not a bunch of BS from keyboard jockeys.

Now for the first question:

When/if a plumb back becomes a restriction, at what boost levels does this generally occur?

Or (more to the point)

When is there ever a need for an atmo bov?

The second question:

Is It really worth converting to GTR ITB set-up on an RB?

I have searched the net for answers and keep getting the same 'he said, she said' load of crap that ends off topic anyway.

As already stated, only answers from users who have done these mods and have the experience to share.

Thanks in advance!

Cheers!

Never a need to go atmo with BOV's.

Yes it's worth it for an rb25 depending on application- dunno about rb20 (would think not).

pretty much as above.

as plenty of threads have... leewah made over 600rwkw ob stock BOV at i believe 30+psi. so no issue.

as for ITB, arguable on the factor of cost its no fken cheap to do for the gains. IMO not worth going there till well over 350rwkw which rules out most setups.

Thanks for the fast replies!

As for the itb's, for me, cost is not an issue and i am just looking for alternatives to a modded front facing jobbie.
