Running My Car With The Stock Bov Removed.

As stated above, i want to know what will happen to the turbo *if anything* if i remove the stock BOV and block up the pipes it carries.

As far as im aware the RB20DET that comes in the cefiro does not have a BOV stock. (Can someone confirm or deny this)

Will it shorten the life of the turbo? cause damage to fins etc etc? Can it snap the exhaust wheel off?

I have a front mount, SAFC II, fuel pump, 3" turbo back.

Anyone?

yeh, like he said, it's not easy to prove for or against, but i mean, many cars block em and last for ages.. Blocking mine stopped the surging i was experiencing in between gear changes.. only problem is the noise, but it's not very audible with stock box on

realistically it'll probably cut your turbo life by about 10 minutes.

YEah doubt itll do much i dont have one and my car is an auto so its always got full boost when it goes through the gears still no damage no end play everything excellent was worried about it when i bought mine but after reading a few threads on SAU couldnt find any thing that made me think i should put one on post-30197-1169037152.jpg

I have a RB20DET and blocked off the standard BOV. It worked really well, sounded good and gear changing felt quicker. Although it started to stall on me every now and then. Revs would just drop down when i changed gears, was very werid. When i put the stock BOV back on car worked fine again. Anyone know why this would happen?

Thanks :laugh:

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
