alright guys trying to figure out exactly where to mount the bov at. i know it should be completely simple and easy but i can't figure out exactly where to connect everything.



this is basically the exact same as mine (the one i have has one other opening on the other side where the pressure escapes)

if anyone could please help out i would be extremely greatful.

oh and pics would be great

oh jdm engine 91 t2. sorry

 

Are you running the stock TMIC and intake duct?

 

You can't.

You're going to need a tune changing the BOV from plumb-back to vent to atmosphere you know?

The stock ECU uses the air flow meter to determine the mass of air entering the engine and adjusts proportionally the air fuel ratio. Since you are venting some of the air mass, the computer will not know this and it will continue to fuel as if there was more air... resulting in a rich fuel mixture. This will cause a heap of carbon deposit over time in your engine and it's not good!

IMO, get it fitted when you get a new ECU and the car tuned!

source?

lots of people have run an atmospheric bov, myself included, with no issues. the motor will only run rich for the brief moments right after the bov opens.

 

you will have to buy a BOV that has an adapter to work with the stock turbo.

 

what sort of adapter?

 

alright so...pictures if anyone's got em. im not worried about the ecu and the fuel mixture running rich because its already a tuned ecu, i simply need to know where to hook up the bov. if there is an adapter needed i can have one made and its not a problem. so if anyone's got some pictures or can show me a step by step process that would be super. thanks

 

Un-burnt fuel? these carbon deposits are going to cause you engine to deteriorate at a faster rate than normal, unless you are going to use some form internal engine surface cleaner every week.

A lot of people do, because they don't know what they are doing. I think it is only fair to let him know what he could potentially be subjecting his engine to.

But seems like he has an aftermarket tuneable ECU. Any decent engineer is going to tell you to get your car retuned after fitting this BOV.

Cheers,

 

Ok my friend now to actually help you with your original questions!

I went and took some pictures of mine, slightly different blow off valve (TurboSmart Sleeper Series Dual Port). I had mine mounted in the same location as the stock BOV, although the adaptor had to be used so my tuner fabricated one from stainless steel and welded on the supplied adaptor.

The plumb back port into the stock intake pipe leading from filter to T/C inlet must also be plugged, just fine a plug that fits and make sure it is held in there.

A pipe must be connected, one end to the vacuum port on the upper intake manifold as indicated on picture below, the other end must be connected to the top of the blow off valve. The T-pieces you see in mine branch off to a boost gauge and other devices.

I hope this helps you in some way mate!

Oh and I'm going to go out on a limb and say those washers that were supplied to you are for jacking the internal spring to adjust spring tension, if you experience BOV air leaking when on boost you will want to increase the spring tension and this can be done by adding washers in a stack at one end...

 

sweet man. thanks so much. this pretty much was what i was looking for. ill let you know if it works. wish me luck.

 

Good luck and watch out for the cops behind you when you vent the air. possible backfires.

 

backfiring is completely awesome. and cops secretly love it...and are jealous...lol
