[Mk2] [Turbo] Refitting Original Recirc Valve - help needed

[dazz_ni45]

I recently bought a rev 2 with a Blitz DV already fitted but I'm not entirely happy with how the car is running as its stalling when coming to an abrupt stop which I am putting down to the effect of the DV on a Rev 2.

The original recirc value was supplied with the car and from studying pics I think I have all the bits and pieces I need. My only questions is how the recirc value is fitted/secured to the turbo/intercooler intake pipe. From looking at pictures its not obvious to me....

As you have probably guessed I'm not mechanically minded and want to make sure I have everything I need before I start.

Thanks

it has to be the original mr2 pipe, the original DV just simply screws onto it, there should be an orange rubber ring/seal on the DV too, screw it onto original pipe then set up the vacuum lines. hey presto!

Thanks, it will hopefully make more sense when I get the Blitz off.

also, the original DV is supposed to be set up to recirculate the air back into the air intake, i.e. there should be a pipe coming from the air intake pipe to the DV, then clamp it to the DV. the un-recirculated air is what is causing the car not to tun properly, iether tht or the spring in the Blitz DV is worn out.

Yip, I have that pipe. I just wasnt sure how the recirc value connected back on as in the pics I have seen of a standard engine there doesn't appear to be any screws? so I wasn't sure if it just pushed in.

the screw is underneath, take the hotpipe off and you should see it. mind that the wee pipe on the air intake should be blocked off if you're not recircing the air.

Thanks. I think that is where I am getting confused as the Blitz appears to be screwed at the top, but there might have been an adapter plate or something.

I will be recirculating as the pipe will be going back on to connect into the air intake.

Thanks for your help.

hi darren,has the problem only just appeared ? only asking as it never happened during my ownership,don't want you to swap everything over,if that's not the cause.paul.

[dazz_ni45]

Hi Paul, no its been there since I got it. Its not a major problem and the car generally runs fine but if you are braking quickly after high revs/acceleration the revs dip and sometimes it stalls (only happened once or twice).

The BOV appears to be the most likely cause and I could live with it but the car is also running rich so I just prefer to put it back to standard as I have a feeling it will help the performance.

Hope things are well with you!

Doesnt have a lightweight flywheel fitted does it? I read in a thread ages ago that lightweight flywheels can cause you to stall as the revs drop quickly. But Ive never had a problem with mine.

Does the blitz have a screw you can adjust to tighten the spring in the dv? if so try tightening it and see if it helps

[dazz_ni45]

No I don't believe it had a lightened flywheel. The have adjusted the blitz bov both ways and tightened the screw as far as it can go.

Its not a big problem and the car will only stall if you have been accelerating hard in 1st or 2nd and then braking hard to a standstill. I just want to see if removing the BOV solves it and adds any performance to the car.

Well swapped the Blitz for the original recirc today and it appears to have stopped the problem of the car stalling. Also a much better gear change and there isn't as much lag.

One thing I did notice is that on full boost the standard boost gauge didn't quite reach the top in 2nd although it did in 3rd but it was pulling fine. It was a cold morning and it was only a short run.

you won't get full boost in any gear until the car has heated up properly.
