I will be changeing my atmospheric setup to a recirculating setup because of really bad bogging and Air/Fuel mixture. Wanted to see some other pictures of anyone elses twin turbo recirculation setup.

I am unsure if I can stay single BOV or weld my second one in and run 2 BOV's both recirculating.

Here is a pic of my current setup in my S13 Vert, Still learning so I would assume that these need to recirculate back in before the MAF's right? I want to drill and weld a end into the cast apexi intake if it is before the MAF's.

recirculation dumps after the maf, the factory maf boots should have a port for the bpv hoses.

I dont have the stock intake tubes, I have Vibrant hoses but it looks like I'll have to re-evaluate my intake hoseing.

Correct me if I'm wrong but didn't a "shop" do some of this work for you? I only ask because I'm surprised that they would allow you to run an unrecirc'd bov with a maf setup.

Also, run the recirc hoses as far downstream of the mafs' as possible. Turbulence can be created when they discharge and give your mafs a false reading, henceforth poor driveability as you are now experiencing.

Yeah they did, so now it's my job to smooth everything out.

Thanks, yeah I did some more research and found that out about running it after the MAFs
now I have to get some pipes and weld in the tube fittings.

Should I run a single SSQV recirculation to a Y fitting to one hose to each inlet pipe?
OR
Should I run 2 SSQV's each with one hose to one turbo inlet?
Anyone know if it would actually made a real difference or not?

no only one bov to one intake after the maf, and switch to 3 inch i/c piping

+1 googleplex on these suggestions! No need to run the recirc to both pipes, 1 will do. Plus GTR's run 3" pipes stock, get rid of that 2.5"ish stuff (sorry for the reiteration sullivan). Also, get that y-pipe fixed so you can drop her lower! There is plenty of room underneath the car to stuff that exhaust away!

I saw the pics on 240sxone but I'm not interested in any of the stock parts, just wanted to see others setups and figure out how I wanted to run mine. I'm just gonna find a I believe it's a 3" 90 degree aluminum tubeing and weld in a 1" fitting and use the HKS recirculation fitting and I should be all set. Thanks though
