I have no idea, Wideband came. Need to pick that up on Tuesday. Umm I guess we can start friday night, no promises. It depends on my friend's schedule and stuff... I'd really like to get it done ASAP though... A Dodge truck pulled up on me on the hwy last night... Goign up hill I hung with him at 140km/hr and slowly creeped by... I was sad.. It's kinda dumb driving around with the SAFC and Boost gauge all lit up but nothing under the hood lolol.

Put the Projectors in tonight... they don't leak (was driving around in the rain). They need to be aimed real bad, didn't have time tonight . Other then that, WIN. Ignore the pics for now, care is super dirty as well as the lights. No condensation, just dirt. .











I'll get some day time ones by Tuesday (day off).

Holy s*** nice projectors man, that a DIY? Keep up the good work on the turbo, this is one of the more interesting threads on nico.

[mikegtr06]

are your turn signals bright enough still ?

[QR25DE]

Brandon did the projectors, very pleased. The turn signal is fine, i'll see if I can grab a pic of it tonight for you. There is a bit of a gap between the light and the fenders, I guess I didn't position the lights correctly/fender correctly when we put it back together. Easy fix. Needs to come apart soon anyways .

Yeah it is a bit dim but I and others can still see it fine. I love my lights though <3. Lol.

Wideband pics:







Now I can make the gauge black as well but I want to keep it white. I have no idea where I am mounting it as it's smaller than the boost gauge so probably rest it on the cluster in front of the milage/kilomterage... lol. I am helping my father this weekend to clean out the garage and stuff. I know I keep saying, next week, next week, etc. but other have schedules and I can't have the car down for a week while I work on it. Aiming for next weekend.

(Still need to be aimed)...











Garage is all clean, we start Friday!

Masking tape holds the bumper foam thingy on, easier for putting the bumper back on later.

RaiderKID: It's from the camera flash... :P

[Blackmobile]

man that's pretty awesome, even though i'm nowhere near getting a turbo (gonna wait until my 6 year warranty expires first) i'm still stuck to this thread like you wouldn't believe. keep up the good work and props for taking the initiative

Looking good

Piping from the TB to the IC is bascially done. Wideband is in.

Problem is it's the daily so putting this all together goes slow... but, gives us time to work things out.

What we played with today: Wideband in and mounted, tested SAFC - Working. We can adjust fuel. Problem is we do not know the proper settings or the IN and OUT on it. It's going to be guess work and comparing with the Spec V's...

Here's a pic, ignore the massive wires (temporary until everything is done then we can reroute them). They may need to be moved etc so no point in putting them in properly for now.





Stock fuel with wideband = pig rich. Probably gain some HP with just an N/A tune on this...

I'll post more through the week. I was gone away with the GF on the weekend. More will be done this week for sure!

What is a wideband?

[QR25DE]

What is a wideband?

Wideband O2 sensor with a gauge. It measure Air/Fuel ratio. Useful for seeing how much fuel is going into the motor. You want to have it balanced.

If you're putting more air, or more dense air into the motor with a turbo setup you usually need bigger injectors. Your stock ECU won't be able to deliver the proper fuel amount thus requiring an SAFC or a standalone to control the fuel. But you need to know how much fuel so that's what the wideband gauge is for.

[2008AltiCoupeDan]

could be larger injectors for better/richer spray, or- increased fuel pump for better psi push. thts what i did on my KA - but tht engine was pure iron steel and the pistons were like diamonds lol- sleeves however were not lmao- plus motor wise the QR is 'slim' and 'toned down' which is why we cant push it to the limit, cus the walls r so tight knit, and sand blown for manufacturing efficiency- not modding effieciency :P

looking sexy tho-

[adidas2go]

The stock computer tune on the v6 is good on the wideband for a/f ratio up to 5 psi. Makes me wonder what the stock injectors would do on the 4 cyl turbo.
