My New D16y7 Turbo Set Up (pics)
 

Been boosted for a couple weeks now, I am pushing somewhere between 4.5-7psi. VAFC says (0.33 pressure)4.5psi, broken out of wack boost gauge says 7. I think I am just pushing 5.5psi cause thats what the Greddy 15G wastegate is set at.

-D16y7
-Greddy 15G Turbo and Ex. Manifold
-HX Intake manifold
-Kteller 2.5" Downpipe
-DSM 450cc blue top injectors with matching plugs and honda resistor box
-DSM 1G sidemount intercooler
-DSM 1G Blow off valve
-Stealthmode performance oil line kit(Great guys and service)
-VAFC for fuel management. Set at -35 2,000RPM+ across the board and -43 for idle. (Runs perfect, but crappy gas milage)
-Testpipe and Greddy 2.25" Catback exhaust
-Slim pusher fan in front of radiator to make room for intercooler
-Autometer boost and a/f gauge
-1.75"-2" charge pipes
-10w-30 sythetic oil

Thats about it, I am pretty happy with my setup, I am hoping to upgrade to a FMIC along with better fuel management. I will get my car dyno tuned pretty soon so I can get my VAFC settings dialed and push the boost to a moderate 8psi. The car pulls pretty good, It starts spooling at 2Krpm and I get full boost close to 4Krpm. The DSM blow off valve sounds so damn good and its pretty loud too. Due to lack of filter on the turbo, its spools pretty loud too.

Questions:
1. Is my secondary 02 sensor ok where it is? (see pics)
2. Why is my autometer boost gauge sitting at 1.5psi when car is off? Is this common problem on autometer boost gauges?

not bad but you need to clean the wiring up just a lil but thats my opinion

Re: My New D16y7 Turbo Set Up (pics)
 

no air filter? :-\

Re: My New D16y7 Turbo Set Up (pics)
 

Not bad, but get rid of the A/F gauge because its useless and get an oil pressure gauge along with oil restrictor. Your boostgauge should read vaccum when not in boost, so yours is not working right. Are u getting ur vafc tuned by a tuner or doing it yourself? You'll be better off just buying a wideband o2 and street tune it yourself. But anyway nice job.

Re: My New D16y7 Turbo Set Up (pics)
 

Just a little worry about your oil feed line. Couldn't you route it in a different way instead of having it going through the manifold ? :-\

indeed, this ---- will be ------- hawt.

Re: My New D16y7 Turbo Set Up (pics)
 

got another pic of the return? from that pic it looks like it dips below the fitting

Re: My New D16y7 Turbo Set Up (pics)
 

No it does not dip below the fitting, and I am not having any smoking problems or leaks at all, so it should be ok :6

Re: My New D16y7 Turbo Set Up (pics)
 

You think it will be a problem? I was looking at that as well, I am not sure if they make any fittings that are angled that will screw into my turbo, but i will defidently look into it. The fitting that came with the kit was straight do i had no choice and plus I would bend the line significantly if I were to put it under the manifold and I would be worried that it would break with the straight fitting I currently have.

Thats what I am debating to myself right now, whether fork out $200+ and have it dyno tuned or $300 for a wideband. The only problem is that I do not know how to tune at all.

Re: My New D16y7 Turbo Set Up (pics)
 

go with a wideband, i know its more money but its worth it. Its really easy to tune the A/F ratio with a wideband and s-afc, all u need is a laptop to record the wideband readings and then change ur safc settings accordingly. My friend is running pretty much the same set up (different turbo though) at 10 PSI, Safc for the fuel manegmnt. He's A/F is 11-12 all the way accross.

Re: My New D16y7 Turbo Set Up (pics)
 

my autometer boost gauge reads 1.5psi when the car is off too. Always was a little strange, but now that the motors built... i dont give a ---- if its off when the car is on too.

i call 3 weeks of abuse with vafc hack an it blows up
