y didnt u put it in the middle one ?? seems like itd go there better

but also if u wanted u can paint those chrome parts if u want i did by the vents already

[QR25DE]

My GF, my friend and I had the same discussion. I wanted it this way because it's closer o the rest of the gauge cluster and a tad easier to see. Plus I already had that side apart lol.

We tapped into the power and ground wires for the hazzard lights switch. So the gauge comes on when you turn on the headlights or have Auto-On turn on. Works great. . Can't wait to drive home to see it move around lol. :P

Looks like an awesome project and I applaud you for your efforts on this! Great job and this is awesome to watch!!!

Just some friendly advice. You may want to switch to a lower boost boost gauge. If you don't planning on running too much boost that gauge might not be that accurate for you. Typically on a gauge that reads that high they don't read the lower pressures very well. I would suggest looking into a gauge with a max of 15 psi. or so.

Keep up the great work though and good luck on the project!!!

[QR25DE]

Hey Kyle, you should send me a Stillen Branded 15PSI gauge :P...

haha, I looked around for them but couldn't find one I liked in 2 5/8" size. Plus if it just goes to 15 PSI it makes the needle move more :P

It's easy enough to swap the gauge, any ones your recommend?

Thanks!

[kyle@stillen]

Give these guys a call!

We use all of their guages for our race-cars and they build some really nice stuff.

I would send you a STILLEN branded gauge but we don't have any LOL.

^^^^that black gauge is hottttttt ide def get that if i was u

[BLKmomba1]

UPS failed me and did not deliver the SAFC today so it should be here on tuesday. We're going to get everything mocked up and tested fitted today and tomorrow.

I'm off thursday as well so hopefully everything will come together at that time.

Sweet gauge, can you tell me what gauge size fits in the vent and what happens when you turn on the heat? did you block the vent so the gauge doesnt melt?

i dont think it would melt i mean that would suck bc my leds would melt too lmao

[DaCoupe]

i dont think it would melt i mean that would suck bc my leds would melt too lmao

well i mean wouldnt it mess up the gauge because when the heats on it gets so hot when i touch the vent its like a stove

Apexi SAFC Neo came today:





Since I'm pretty much the "tester" for all this crap, let's make a good note of the AEM FIC DOES NOT WORK (without a lot of modification) with our 2.5L QR25DE motors.... (could have saved some time and money but if you don't try then you don't know.... right?).

Anyways, hopefully this will work, I see no reason why it shouldn't... soon Alti soon... I've used the SAFC Neo on previous cars so I'm pretty familiar with it... should be a blast.

(Alti is the name of my car lol)

[rjdmmfl1]

this is by far my favorite thread on NICO... I can't wait to see this completed

[rjdmmfl1]

I agree, this is the most positive and informative 1st post I've ever seen on NICO. Stick around dude, we need more guys like you here!

Hey Scott, i was lurking around here and found this. Pretty cool someone is actually taking the initiative and boosting a 2.5 alti. I have a boosted 02 se-r spec v. hella fun to drive daily.

heres some advice...

seeing as the qr isnt any different between the altis and sentras, you WILL make more then 230whp. your motor CAN handle 300whp with a nice tune.

the manifold you bought is a good mani for the price. its a replica of the Autoboost manifold. that company is no longer running though. I have the same mani

good choice on injectors!! simple plug-n-play thing

i would switch up that WG for a tial or turbonetics piece. the ebay stuff tend to get stuck shut and you really dont want that. overboosting sucks!!

bov, not my taste, but great choice nonetheless

intercooler looks pretty decent, should work fine.

the piping, if anything like the routing for the sentras, should be fairly easy to set up. just a few cuts here and there, and you should be set

the turbo might and might not last you. ebay turbos are a hit and miss game to get a good one. if you see any signs of the seals going bad, i.e. shaft play, i'd get it rebuilt with garrett internals. look up BlaastPerformance. they are in canada

Now onto psi levels..

5 pounds with a decent tune will get you the 230+ whp. maybe even more.

10 pounds with a decent tune will get you 280+ whp. depending on tune and trim of that turbo, you may just reach the 300 whp level.

12 pounds will be a for sure 300+ whp setup.

*this is all on stock internals. all the OMFGFORGEDINTERNALSBATMANFOR7PSI is a bit dramatic to be honest.

a have a local buddy that runs 9psi daily and 12 psi for the races. he has yet to blow anything. the qr is very under-rated when it comes to power levels it can handle.

I will suggest this, make sure all your vacuum lines for wastegate/bov/boost gauge/boost controller are routed 100% correctly. i'd have to say the vacuum lines are the biggest headache of the whole install.

i am assuming you are going to attempt this on your own. if so, give a whole weekend, as in saturday-sunday deal. i did my install in 13 hours from first bolt to first start up. but i did miss a couple small things. make sure you have everything 100%, no leaks all bolts/clamps tightened, etc before starting it for the first time.

I think thats all i have for now. if you have any questions i'd be glad to help ya out.

Hey Doc, at first I thought your post

I agree, this is the most positive

was a response to your post immediately before lol.anyways, still super excited about this thread.

No offense Ricky, but I think it would be kind of funny if you finished this before SFR finished Ricky's car.

by the by, Ricky you need to hurry and get your car back so you can start going to meets again (in your coupe)

PURE SEX

Werd

but no seriously i cant believe u got rid of it its so dissapointing it was the first super sexy one ever lol

this is by far my favorite thread on NICO... I can't wait to see this completed

werd i <3 it too

[QR25DE]

Update:

The Apexi SAFC Neo works! And by works, I mean the car runs with it and it reads:

1. Throttle %!2. RPM/Tach signal: What we configured was the SAFC to run in 1 Cylinder mode, tapped the ignition signal to one of the coils, DONE. Read RPM exactly!3. Read Volts.4. No check engine lights, no stuttering etc.

Now here's the question and I can probably find this somewhere but what should the MAF be set to for IN and OUT? Right now I have it set to 4 in and 4 out and the car runs fine although we haven't made any adjustments. I figured to go with this setting just because it works on my old Neon hahha.

I will be doing some more research. Unfortunately I work this weekend so another delay in progress, however the weekend coming I have off.

What needs to be done:

1. Get the car to run with the SAFC on the WRX injectors. -- By the way, does anyone know what the stock ones are good for in CC? maybe 240 or 270cc? Let me know if you do.

2. Mock up and mount IC and piping (most of which is done because we have a good idea where things are going.

3. Down pipe, oil lines, etc. etc.

Soon I hope, it was 6C this morning when I woke up... a reminder that winter is coming soon.... :S

[Rob.Vegan]

I love updates. How soon do you think this will be completely finished ???

it was 6C this morning when I woke up... a reminder that winter is coming soon.... :S

Yay, snowboarding time ! ! !

[QR25DE]

Shooting to get *most of it done* this upcoming weekend. I have tuesday off to play with the SAFC / new injectors. I want to get the motor running stock on the new injectors before we start any turbo stuff. The injectors may be a tad too big. Might see what we can shoot for on the stock injectors.

[mcheddadi]

turbo builds are the BEST!!!

[PHENOMenalVinyl]

Yay, snowboarding time ! ! !

hahha werd

[mikegtr06]

Updates ?
