N/A Q45 0-60 5sec 1/4mile in 13.5 detuned a bit.

[N/A Q45]

New on here but not new to cars-

I bought a 94 Q45 for my girl and I can't seem to find many if any people that have a N/A running what this thing does. Just wondering if there's anyone that knows of Qs running 13s in the 1/4 N/A and what hp/tq they make and mods they did, as it olny cost me about 80 for the intake I setup and I swaped injectors that I had from my other cars + a few other little things.

[elwesso]

Low to mid 14s is what you'd expect stock. You won't be running mid 13s N/A.

[N/A Q45]

Well that would be good if that made sense but it does run 13.5s detuned a bit with tire spin even going in 2nd- and a 0-60 of 5sec + 60-100 under 6 -- N/A! Maybe just no one has tried what I have done but it works and I have some videos to back it up. + it gets 24mpg if drove easy-

[qship96]

Both of you must be using Chinese watches to come up with those times......stock 90-96Q is a mid-high 15 second quarter mile if running like brand new.......not 14, and laughable to even think 13 is possible with "minimal mods" unless you consider cutting out enough leather,plastic,and sheetmetal to reduce the curb weight by a few thousand pounds!

[N/A Q45]

Oo boy.. Nissan240sxKA is where the videos are- and I already know the Qs are slow stock, I olny ran a 14.9523 @94.48mph and 2.4160 60ft with just the injectors, wrong size intake and glass packs that were holding it back. But now I've got it tuned rather well and maybe you don't know how to setup a N/A but don't come to my post and talk when you haven't even seen what it will do. You're just making an uneducated guess.
This car will turn the tcs on no problem at 100km with 235s at 29psi. I'm just glad to know I'm probably one of the first or few to wake these engines up N/A. And that 13.5 1/4 is with it sligtly detuned for the up coming winter if it gets here. Every N/A Q needs to be set up like this one so people can stop thinking they are slow-

[qship96]

I call total s***

[N/A Q45]

^Sad..^ But like I said said the videos are on youtube of 0-60 and 60-100 stock injectors and injectors swaped and the tcs coming on at 100 I've got nothing to prove so I could care less if you call b.s . All I know is I don't need any turbo and get better mpg, who who on here can figure out what it is I've done to get these numbers? If you're all so knowledgeable then should be easy, I olny had the car a week before I clued in that it was not running what it could.

[paranoidjack]

Could you post the links to the vids? I'd like to hear it with some packs on it.

^heres a little burnout at the 1/4 with the glass packs and when I first got the car from 80-160ish


And here's the one after I got it tuned from100-160 staright pipes

Links don't work..

[N/A Q45]

Another reason I hate blackberrys- these phones are about as good as a civic for drifting-

All the links work.. But it looks like they are all the same. I'll try again but after that people can just go to

Niss240sxKA

on youtube to see.

It works if you remove the "m"

[N/A Q45]

Well atleast it works then.

But back to topic, it seems that no one has done this with a N/A Q45 before? I just doesn't make sense that nobody has figured it out.
This car is just a beast and has got to be the easiest hp gain for $ I've every done or heard of. These engines just more or less need a tune and a few other little things to make this kind of power and mpg gets better. The car has to be around 400hp to do what it does. Doesn't seem to be much interest about going N/A on here. O well.

[Lokim]

I'm dying to see under the hood! What all did you do? That thing sounds wicked!!! How about a tech writeup???

[N/A Q45]

Edit- I must have made it all up, so no point in anyone seeingwhat I did-

[elwesso]

So basically what you've done is leaned out the mixture by going to smaller injectors (270cc vs 370cc), and advanced the timing. Effectively you've done the same thing that an ECU tune gives you. You might have gained 30HP by doing this. The "cold air intake" and exhaust have probably netted you nothing, but just for grins I'll say that gained you 10HP combined. Going to the iridium plugs is probably a level move, although you did move to a colder range than stock which would help now that you're running a little leaner.

We know that you can gain about 40HP N/A with a proper tune. So, assuming the VH comes with 300HP crank from the factory (not an unreasonable assumption), 340HP is about the max you can do on an otherwise stock engine. It's well known that "cold air intakes", regardless of your setup, will not gain you anything but more dirty air in the engine. You can get secondary and tertiary effects of a "cold air intake" by fouling the MAF and causing it to run leaner than it's supposed to, but that's not from the cold air intake doing what it's supposed to be doing.

400HP N/A on a VH45 is only achievable with higher compression, modified camshafts, or both. Basic thermodynamics tells you the easiest way to increase an engine's thermal efficiency is by increasing the compression ratio.

BTW, it's easy to smoke cheap or bald tires, making the car seem way faster than it actually is.

I have taken my Q basically to the limits that you can take a N/A Q to, which is a full exhaust with no cats, "headers", tuned ECU, 5-speed manual, and it's not doing a 13.5 in the 1/4 mile. I can tell you it's not putting out 400HP, maybe 340-350, but not 400.

14.9 in the 1/4 mile for what you've done is believable. 13.5 is not. If you think it is, go to the quarter mile and line up against basically any stock G37, FX50, CTS-V, 370Z, or newer mustang GT. All of those cars do low to mid 13s. If you beat one of those cars in a fair 1/4 mile race from a stop, I'll eat my words. Recently, I had both my Q and a stock 2005 CTS-V. The Q and the V are basically the same weight, but the V has 400HP and a 6 speed manual, compared to the 5-speed manual in my Q. The V is way faster than my Q, and my Q is basically modified to the limit of what you can do with an otherwise stock VH45. My Q is probably putting out about 340HP with what I have done to it. I haven't done a 1/4 mile in my Q, but that would be interesting to see.

You could have avoided all that hassle and installed one of my ECUs for the same or better result.

[Lokim]

Out of curiosity, why 270cc injectors? The factory Q injectors are 370cc...

[N/A Q45]

Well I'm glad Lokim asked the million $ question.

And I am truly sorry for you elwesso as you just don't buy an ecu and settle for 340hp. The whole point is to get the gas to be all use that the injectors spray, and as I've learned from my KA these 270cc's have a great spray pattren when you add a lot of fuel pressure. This car will leave most fast cars sitting wondering wtf happend if you're olny at 340hp the tires on the rear are maxxis MA-Z1 victra's and they can hokk if you pedal it and it was running 14.9s before most of the things I listed. But I don't care if you believe it or not the car just hauls a**!

O and your whole thing about the cold air not doing anything, that's how I know you didn't setup yours right because cold air is always better then then hot under the hood air. The biggest thing that slows this car down is off the line it just doesn't hook if you floor it, it just kills the tires-

The timing helped a lot as well, stock timing is a waste of what the engine can do.


You need to learn the olny limit with your car making more power is the knowledge you don't have. Not tring to seem rude but its true.
What does your car run from 60-100, 0-60? Hell the VK45 is 340hp and olny makes that Q a 5.7sec to 60 car and mine consistently runs 5-5.2.

[qship96]

I put a "Redline Oil" sticker on my bumper,pinched off the fuel lines, put a banana in my tail pipe, and my Q now does 0-60 in 3.5 seconds and the 1/4 mile in 12.9 !!!!!

Somebody seems to have been "tickled" by Elmo .

[N/A Q45]

Lol I don't want to hear about your fantasy of your Elmo sticking his banana in your tail pipe-

My videos don't lie, just because no one has seemed to be able to get their N/A Q up to what this one runs doesn't mean you should shoot your mouth off in a sense -online- but I know you use all your brain power to come up with that one, your olny problem now is you need to find a new brain that works and just give yours to Elmo so he can look even more dumb sitting on your dresser-

I would really hope this fourm has more talent and knowledgeable people than qship96-

[qship96]

nobody believes you...........nobody.

[N/A Q45]

Well that's more then fine with me if no one does lol- its not my car that's running slow.

I just came on here because I can't believe it myself just how quick this thing is from what I've done + I forgot to say that I re-did all the grounds including each ground wire at the ECU. Every little bit helps as most people I would hope understand that the factory grounds just are not as good as they should be.

[yodawill2000]

A verifiable Dyno is a must.
Else all will agree with QShip96...

[N/A Q45]

Ya I have a dyno right around the corner-

[N/A Q45]

I'm not here to care if anyone believes me, just was seeing if anyone has done this before- and I take that as a no. Which is what I wanted to here kind of.

[qship96]

stick with the kidde forums if you wish your BS believed and your ego stroked. Yeah,adding ground wires is a real horsepower maker,almost as much as a few stickers and japanese writing on your fenders..........

[N/A Q45]

Now that's funny that you say that^ go do some research and you will find you can gain hp by having everything grounded properly. Any more like you on here? This is why I don't really care to go on most fourms, everybody knows everything and you can't teach them a dam thing, kind of sad but if it helps you sleep at night knowing you put in your two cents that's not worth one.
I worst part is you're serious...
I didn't even say that I gained hp from it either, just saying what else I did.

[qship96]

yawn.Go put some Clearasil on those pimples,and finish your homework.....that big yellow bus gets there early in the AM.

PS...just havin fun with you!

[elwesso]

My cold air setup brings in air just behind the front grill, so it doesn't get any "colder" than that.

As long as you're happy with the vehicle, that's all that matters. None of us here have to drive it.

96 Km/h is 60 MPH, and I was seeing about 6 seconds which is about right for what you've done, I timed the video anywhere between 5.7 and 6 seconds... A before and after dyno would be about the only way to fully convince me. BTW you're transmission doesn't seem the heathiest... 1-2 shift isn't bad, but 2-3 sounds like it's slipping a bit. its really tough to tell off those videos because we all know the speedo isn't super accurate.

Regardless, it's cool to see another approach to getting the same place. Certainly sounds great! Do I think you're doing 13.5 in the 1/4 mile? No, I don't see how that's possible, because the lowest recorded 1/4 mile of a N/A modified Q is 14.2 @ 99 MPH... You might be doing 13.5 seconds in the 1/4 kilometer (0.16 miles)... I welcome you to go to the drag strip and have someone record a video showing the ET and trap speed on the track display, and/or a time slip.
