hay guys

Basically im wanting to know wat would get a 4sp auto into 13s. My 6th gen did a 14.3 with headers and full 3" catback and nwp spacers. My auto was slipping pritty bad in these runs and reckon a 14.2 would be a pritty easy effort now with my gearbox not slipping and cooler fitted. My car is the australian spec maxima same engine but they definatly detuned the australian model maximas over the american ones. My car after adding the exhaust system blows alot of smoke when getting up her like its running rich. So i reckon a tune would make a big difference. Let me know your thoughts?

cheers kurt

 

Spray

 

Keeping in N/A pal

 

Detuned Engine... blowing smoke..

I would say go take a few runs in the car first to see where you stand. Then you can determine what it will take to get into the 13 second range.

 

You mean all-motor, since N/A means naturally aspirated?

 

Strip a few hundred pounds of weight if you really want speed. I mean take all the seats out, pull all the sound deadening, the carpets, the door panels, take the spare out, put in a little gel battery that weighs nothing, put the lightest rims you can on. As a general rule, 100lbs=1/10th of a second in the quarter.

 

I'll second sciff's comment.

I'd also add that you would need a Transgo HD2 shift kit, wideband, AFC, and look into a larger MAF. Firmer mounts, particularly a torque mount would help get the power down. Not sure off hand if Aaron's torque bar or Knights poly mount works on the 6th gen.

This may get more answers in the all motor section if you've not looked there.

 

I think the tune will be a really nice gain. Wat are other quick 4sp autos around this forum. Any into the 13s.

 

Look up the DR mod. 7200rpm ecu flash, EMU, etc.

 

3.5 or 3.0?

 

If its a 02-03 maxima auto get 3" intake, headers, catback (2.5" or 3"), pulley, dyno tune (safc and wideband) and a trans-go shift kit. that will eaily put u in the 13s with street tires.

 

1sxyleo (13.6) and grand_hustle (13.7)

 

Not if its a 15 second car currently

 

yes it will its been done.

a stock auto 5.5 gen is capable of a 14.6 stock.

those mods free up a lot of power on the 3.5 and those are the times it should be running. Im not talkin out the side of my ***, im speaking based on what i saw with my own eyes

 

That would be true.

 

Exactly my thoughts after I posted lol but I was too lazy to edit and post that because if they were serious enough it wouldn't matter anyway. Just tried to get the ball rolling. People, don't sleep on the auto. It is not fun but it is quick.

 

And until you've seen this particular car run 14.6 you are talking out of your ***.

He said it was smoking.. who the hell knows, the thing could be running 4 cylinders for all you know.

Go get a baseline run to know your starting point, everything else is meaningless until you do that

 

that just means he is burning oil....that doesnt effect performance


^^^^untuned auto with ssim, obxv1 headers, 4th gen sri, cattman 3".....i rest my case

 

i was gonna say i've seen (on the forums) the most power come from custom intake manifold work and a tune that adjust air/fuel, timing, and brings your redline up 1000rpm. they net 20-30whp with that alone.

But, i figure for basic bolt ons without tune: 2.5 or 3" exhaust, short ram intake or Ghetto air box, Block off plate, headers or gutted pre-cats, intake manifold spacers, and sticky tires will get you to 13's if you are at lower altitudes.

 

You don't need to post videos... I am very familiar with the 5.5 gen and stopped caring before you joined this forum.

You must be gods gift to mechanics. Tell me great know it all, whats wrong with my 1989 Rx7, It doesn't run 10s. I'm sure seeing as you are obviously a psychic mechanic you must have the answer. Just tap into you're mental OBD2 connection and read my code while your over there giving bad advise.

 

I didn't know an '89 Rx7 had OBD2!

j/k !!

 

The smoke isn't oil smoke it looks like its running rich black smoke. But that 5.5gen doing a 13.8 is impressive without a tune.

 

You want a cookie?

1. its a piece of $h!t....and do u want another cookie?
2. how am i giving bad advice?......he asked how to get a auto in the 13s and i told him the basics to doing it

yea possibbly running rich or clogged cats

 

Not even going to waste my time with a meaningful response, you don't even understand what you don't understand/

Because these issues wouldn't be good to look into first before slapping a whole bunch of parts on your car and hoping for 13s.

Let me ask you something.. how many 1/4 mile runs have you done and whats you're best ET?

 

If you are serious then first look at the tranny. Higher stall torque converter FTW, then with some spray your 1/4m times will drop on the quickness and if you blow the engine then just swap everything over. These engines are too old and too cheap to mess with the internals unless you know exactly what shape your engine is in and obviously have the money and know-how to do it. 13's are not unrealistic at all

 

he asked what will it take for auto to get in the 13s so i told him what it would take for a auto 5.5 gen to run those times. any person with common sense should know to fix the problems before slapping mods on the car. If the cats are clogged slapping...headers can fix that issue, if its running rich...then tune it




quite a few actually my black 6spd went 13.4 @ 105 with a 2.0 60ft

and my most recent 6spd i sold went 13.7 @ 105.7 with a 2.1 60ft on bald street tires. As a matter fact that auto i posted that ran that 13.8 @100 was my car. the original owner ran that time auto. Did the 6 speed swap and i bought it from him and ran that 13.7 @ 105

 

Seeing how bad these auto trans slip between gears, a better valve body should be at the top of the list...right after lw wheels with drag radial/slicks.

Cheapest way to a faster track time:
Get a cutout or remove the main cat for the track. Easy and instant power.
Do the drop resistor mod. Easy and reduced slip between shifts.
Lightweight wheels with slicks. Can be cheap or expensive...depending on how knowledgeable you are
Transgo HD2 kit for the valve body. Might not be cheap...but is well worth it, if your looking to track often.
Large ties to hold the sloppy stock suspension in place. Easy and reduces wheel hop.
40+psi in the rear tires.
Seafoam. As easy as filling your oil burning motor with oil
Gut gut gut your car. 100lbs = 1/10s

Take everything with a grain of salt...there are many ways to get into 13s, but if you want a 13s car on the streets, a lot more money is involved.
