IS THERE SOMETHING I NEED TO DO TO GET WAY BETTER TIMES THAN 16S???AS ALL I AM DOING OF THE LINE IS SPINING!!!!NOT CHIRPING SPINING AND THAT WAS LOWERING MY TIRE PRESSURE DOWN TO 28 PSI!!!!! I BOUGHT A CHIP FOR MY CAR BUT I HAVE THE COMPUTER THAT CANT BE CHIPED SO IF ANY ONE HAS ONE OF THOSE LOL THAT TAKE THE 14 PIN EPROM LOL!!!!ANY SEGESTIONS WOULD BE GREATLY APPRICIATED AS I WOULD LIKE TO GET THIS CAR DOWN INTO THE LOW/MID 13,S WITHOUT HAVEING TO USE NOS!!!!DOES ANYONE ELSE DRAG ONE OF THESE CARS FOR FUN LIKE I AM AND USE IT AS THERE DAILY DRIVER!!!!!! THANKS KEVIN IN CANADA

I dont drag the J but I helped my bro drag a hot rod camaro back in the day . (High 9's)Error #1 is spinning the tires .Even the 2000 HP rods limit that by letting the clutch slip.If wot spins the tire then you need to feather into wot .I used to have the time loss calculation for every revolution the tire spins but thats long gone in the old brain archives .Traction is the battle you face amigo.And FYI the caps lock gave me a headache.

PS. We used to do a bleach burn out before the run , not sure if they do that these days .

[Skapunk4everr]

^^^ 100% correct.

dont rev it up all the way .... try revving to like 3,000 rpm to eliminate a long burnout, and then after the wheels catch pedal to the floor.

i hate to break it to ya, but in order to get the j30 to go below like a 14.5 you will be spending tons and tons of $$$. MY suggestion to you is, if you want a 13 second car, and still want a nissan, look into getting a 240sx, and maby get a turbo for the KA24 engine, or even an sr20det. 240's are sweet and cheaper and more universal and trying to make a j30 do 13's.

and for the eprom, you are SOL unless you use a 300zx ecu which may just cause problems for you in the future.got any pics of your intake set-up?

[yodawill2000]

Ditto on the intake pics !!!

You gotta keep in mind this is a HEAVY sedan ..Motor says lets go ..Physics says ... "In due Time"

[kccake]

thanks guys for all the info so far!!!!! but how do i get to hook up i had camaros and mustangs too but i needed a 4 door(kids)lol!!!when i had trction probs a good olle set of traction bars and bigger fater taller stickyier tires worked!!! what abought changeing rear end gears,is there traction bars you can get for these or a 300zx,ect all info will help and yes i will post pics of my intake as soon as cammera gets back to me prom pics lol!!!!so remember all info will help as yes it is for fun for me but i dont want to look like a dork!!!! also lol ps remember no nos yet lol thats later lol!!! lets just do some tweaking first with nat asperated ok lol!!!! will look soon for some moer posts and thanks again i knew this post would draw some attention lol!!!! pretty funny going down the drag strip against a 500 horse cuda with a booster seat in the back of the j lol!!!!!and my 3 year old son on the side lines yelling go daddy go lol thats all worth it 16s 17s ect!!!!

[Skapunk4everr]

from what i understand the Differntial from a 300zx may work on the j30, do a search im sure you can find out somthing because i know we have talked about it before.

if you have the $$ look on stillen and buy the 300z Plenlum, and while thats off you can get some new pistons and ect. Also look into the Cam gears. Only if your into ripping your engine completly apart

ps. you can gain 5 hp by eliminating the LOL ' s and the multiple exclimation points

[gr8scott72]

I don't think you will ever get to see even high 13's without nitrous (NOS is just the brand name) and I predict that you won't do it even with the nitrous.

You would need to hook up perfect (which it doesn't sound like you are doing) and still have over 350 hp to get to the mid 13's. That's a HUGE amount of nitrous.

[gr8scott72]

What are your 60' times and on what kind of tires?

[J30tman]

I just want to know how you get the tires to spin out of the hole? The only time my J will spin is in the rain or on sand/gravel.

ok im just on goodyear street tires size 225 55 16s and only running 28 pounds psi in them and still spining as for how im spining thats simple when i stag for the lights i rev up to abought 4 1/2 grand and hit the gas to the floor and everyone says im spining for a good 2 to 3 car lenghs before i hook up!!!! im wondering if i go to a set of rims and tires like i did in the old days with the mustangs and camaros and go like 16s front and wide 18s in the rear !!!! i dont know im pretty disapointed in the whole thing my grand prix 3.8 was geting high 14s stock with just a k&n intake and it was a heavier car????i very disapointed in the j to the point were i think i might get rid of it!!!! just wanted to have some fun but not look like a real dork doing it lol!!!!!

[J30tman]

These things don't have a stall in them nor were they offered with a standard transmission. How are you getting the rpm's up to 4500 with it in gear? Are you in nuetral and then slaming it into gear? That would be a good reason you are spinning the tires for so long.

Are you reving it in neutral and then dropping it in drive? I hope not.

And no, the 16 inch tires with the taller sidewall will do better for drag. You can actually drop them down lower than 28. Probably around 20 psi.

You need to be launching so that you are barely breaking the tires loose. If that means less gas when starting then give it less gas. Wheel spin is hurting your time.

What were your 60' times? With wheel spin for 2 or 3 car lengths I bet they were 2.6 seconds or worse. You need to get the 60' time down to about 2.0 seconds for a rwd car on street tires and about 2.2 second 60' for a fwd on street tires. It just takes practice.

The Grand Prix GTis just a little lighter than the J30 and the GTP is just over the J30 according to edmunds.com. Did you have the GT or the GTP?

[diamond]

i run the same size tire as you.mine will not spin.but my car dont spin like a normal one anyway.lol.it will take over a hundred more h.p. too.i got 436 gears and i dont think it would even be close to 14,lol.you can make them handle great but trying to race a j is useless as far as im concerned.lowriders will kick its ***.lol.and wouldnt that just suck!

[Rex]

Maybe it's just me, but I don't see any way to get a J30 into the low 14's or high 13's without spending ~$10k. And I'm almost positive it would either take a huge nitrous shot or some forced induction.

I'm also curious to know how you're launching (power break or neutral slam) to gett he car to spin that much for that far.
