I have a blitz dump valve fitted to my HKS FMIC and want to change to a standard type. Probably an obvious solution but I can't find it.

Help, as always, much appreciated.

Anyone???

I simply want to know if you can fit a recirc type d/V with a
FMIC.

 

Yes, you can, as I did.

I have a hybrid FMIC and different air intake pipework to you, but I found the best solution for me was a Forge recirc for a MY97-8, with a variety of Samco tubing.

 

Hmmmm, a bit of engineering involved then.

Thanks for the response, Jay M A

Anyone else with some advice?

 

BTTT

Anyone else with a FMIC and recirc?

 

You will find that anyone who does will have done the same as Jay, you can use a std 97/98 dump valve instead of the forge item.

Any recirc will need plumbing the same way though as it needs to recirc back into the intake.

Id go APS mate its a dual type valve but is well recomended.

oh it has an adapter plate

What is the difference between a 93-96 dv and a 97/98 item?

 

The 93-96 DV is straight entry/straight exit, it is only 15mm OD.
The 97/98 DV is straight entry but exits 90 degrees which helps with the FMIC kit, it is also 25mm OD (iirc) like the FMIC pipework so no need for reducers etc.

Am i to assume that an aftermarket VTA dumpvalve for a 93-96 is more than likely exactly the same as a 97/98 but with a different fitting kit?

 

Depends on which brand, forge for example replicate the std fitted items for Recirc but the VTA ones are the same part number IIRC. Albeit with diff fitting kits.

I'm looking at a bailey VTA

 

In that case there is two different part numbers for ver 1/2 and ver 3/4, i suspect that the difference is in the fitting kit though.

Make sure you keep hold of your std dump valve if you are fitting the baileys one.

have you tried it without the dv as i have tried atmospheric and resirculating with my fmic but recently blocked both pipes and run without car running great hitting 16psi no hesitation great spool up, only tried it without as dv started sticking now not putting one on at all..

 

I don't wanna risk the turbo, so no
How does it sound?

 

SOUNDS GREAT AS HAVE BLITZ SUS INDUCTION SO DIST AIR SOUNDS LIKE A DUMP ANYWAY AND MAKES NO DIFFERANCE TO TURBOS SPOOL NO CONCERN WITH TURBO JUST THE MAF AS BITZ CAN BLOW MAFS BUT MINE HAS BEEN FINE OVER 10 MONTHS NOW

 

Nice one lads.

Any one know the part number for the standard DV 97/98. Also, specifically what pipe work will I need so I can get it ordered up.

Cheers

J

 

will look for you when i get home tonight i might still have the standard one from my 97uk in my garage if so will let you know just need some hose and clips from any car spares

 

sorry j stripped garage could not find 1 good excuse to tidy garage though
somebody on here will know the part no...

 

No problem, thanks for trying

Anyone else have the part no. for a standard 97/98 Dump valve?

Not OE though

 

Any benefits to the APS unit. How much would an OE set me back?
