Hi Guys,

Ive got a Greddy Type RS BOV which i managed to get for free. Im getting my mechanic to install it with a plumb back setup. Now my question is, the adapter is too small for the RB25 flange & you cant simply just buy an adapter for this BOV to fit an RB25.

At the moment I think my mechanic is going to be either make a custom adapter to fit it to my standard RB25 flange or he might just weld it to the cooler piping.

I personally think id prefer it custom fitted to the flange on the inlet with the stock BOV originally is factory. Mainly because its neater and ive heard the BOV should be as close to the throttle body as possible...

I know its a wanky topic but would appreciate your help/advice.

Thanks

Dean

i have one that is welded to cooler piping no problems!! however i agree it should be as close to throttle body for sure as when throttle is closed it can vent as much boosted air in the pipes (back to intake in plumb back or to atmosphere). However you can buy a flange that should work for rb25 man.

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
