j30 intake and headers

[kbflip02]

new to the forum but have followed quite closely for some time now...i have several questions for anyone out there:1)since there arent ANY aftermarket parts out there how much of an improvement if any would there be between the Jim WOlf Pop Charger as opposed to the K&N filter with the air box i have now2)is $400 US a good price to get headers fabricated...i have replaced both cats with hi flow cats and the resonators with magnaflows and then piped it out the driver side making it look stock...i went with 2 1/4in pipe starting right before the cats...3)is it really cost efficient to have a "cold air" kit fabricated for $3004)if i upgrade to bigger injectors am i going to need a larger fuel pump5)if i upgrade the cams would i have to change the valve springs as well6)does the JET ecu upgrade really work and is it worth it7)are there any aftermarket underdrive pulleys available such as the ones for the Z32 N/A8)would it be worth it to change the fan to an electric fan(as far as less stress on the motor) and is it possible9)hypothetically could i port and polish the head?10)and lastly after all of the above would i have to get my ECU reprogrammed or upgraded anyway and if JET doesnt work who does???

sorry to throw a bunch of things out there but I LOVE my J and to be honest with you its the 2nd one ive owned

any information would be greatly appreciated

oh yeah and one more thing how much would some custom shocks/struts cost and who would i have to get them from...Monroe???

Some J30 owners on this forum in the past have added the JWT pop charger and dynoed the car. I think the gain was between 15bhp and 20bhp.

As far as I know there is no ECU upgrade that works for this car.

Custom suspension parts would have to fabricated custom by a custom builder, its more expensive then Nissan OEM. Since there is no aftermarket for any suspension components on the J, your only option is Nissan OEM. If you buy through everythinginfiniti.com you'll get them cheaper then at a dealer.

now would the JWT pop charger make that big of a difference compared to the K&N air filter i have in the air box now???also do u know if anyone has removed the fan and added an electric fan???i wonder if that would actually put less stress on the motor or if it would mess things up....id like to to do that and get underdrive pulleys if possible before i start messing with the injectors and cams...unfortunately i dont know alot about cars i just have a semi descent understanding of what does what and if i changed everything i would like to how much of a difference things would make....in theory it all sounds great but who knows...anyways if u have any suggestions or any other ideas please do let me know-K

No. Just more noise.

also do u know if anyone has removed the fan and added an electric fan???i wonder if that would actually put less stress on the motor or if it would mess things up....

Probably wouldn't hurt anything but sounds like a lot of fabrication work.

id like to to do that and get underdrive pulleys if possible before i start messing with the injectors and cams...unfortunately i dont know alot about cars i just have a semi descent understanding of what does what and if i changed everything i would like to how much of a difference things would make....

You don't know alot about cars and you're talking about changing injectors and cams?

in theory it all sounds great but who knows...anyways if u have any suggestions or any other ideas please do let me know-K

Suggestions: do a few mods to car to make yourself happy, like the underdrive pulley you talked about (I have one on mine) maybe the exhaust and the intake but leave the rest of it alone.

If you want a fast car, start with one that doesn't weigh almost 2 tons to begin with and is cheaper to mod.

yeah i dont disagree with you however i DO know what i want and basically its all just personal preference u know???i definately appreciate your input though...by the way what kind of underdrive pulley did u get???i think ill stick with the K&N since it will be the same as the JWT pop charger unless i can get an ACTUAL cold air intake fabbed then maybe ill throw that JWT on there just cause...ill keep you updated in all the other stuff i plan to do as it comes together however that might not be for awhile since my fiance and i are planning our money in march which is where all my money is going now...personally i think if it all comes out how i want it and its done right it will be truly unique...though it wont be a twin turbo it will still be something no1 has ever seen or done...frankly your right that the car is heavy but thats why no one has ever really gone the "extra mile" to truly increase its performance...i like different though...different can be good...-K :

Nobody does custom J30 ECU programing so if you want to start messing with injectors and cams and such you'll have to learn how to reprogram the ECU.

Hope you have deep pockets.

why not just get some VG30DE N/A Headers off the internet? They should work.

[kbflip02]

they wont fit...the only thing the j30 N/A 300ZX's have in common is the motor and transmission if im not mistaken...

Steering column is in the way.

[brandonjustice93J30]

I think this came up a while back....doesnt someone within the forum have the ability to program...and was going to sell chips for around $150?

it's been since sometime last year since it was mentioned

[yodawill2000]

Drape does it ..he was selling them on Ebay.

i also went ahead and called Jim Wolf Technologies and they said they can and have done it in the past...plus get this i did some searching last night and found 2 companies willing to make custom suspension components...one called Ellis Engineering for the Shocks and struts and a company called NEX said they could do a coilover system however both companies were interested in the quantity in which i was requesting so i told them we would start with just for one car and see how the product works as well as pricing and then we could go from there...anyone else interested???

[yodawill2000]

Depends on the price.

[brandonjustice93J30]

http://cgi.ebay.com/ebaymotors...60005

that's just slightly cheaper than JWT ot Jet...lol

I'm thinking I'm gonna order one myself for $39 plus s/h.

[kbflip02]

let me know how that EPROM chip goes...im defiately intereseted ive just heard horror stories about them in the past

[kbflip02]

ill post the prices as soon as they get back to me

[gr8scott72]

I bet JWT quotes you well over $1,000.

edit:Looks like they have them for $595. But that is just there standard programing. It would still probably be over $1,000 if you needed custom tuning for different cams, turbo, nitrous oxide, etc.

If I can talk the wife into letting me spend the money on a part for my car to make it faster, when she thinks I have enough of a lead foot now. I'll order the chip and do a report on it. lol

I'd be willing to bet a minimum of $500 for the headers being custom. I think the 300Z ones from Stillen were already in the $350 range when I looked at those, before I was told they wouldnt fit due to steering column clearances. And I'd figure in the minimum $1000-$1500 range for those coilovers...if not higher for a one off set.

I agree. I never said any of this is not possible. I'm just pointing out that it is VERY expensive and you are tuning a car that not many people have tuned so you are going to have to do alot of trial and error type testing. If your pockets are deep enuf and you have the skills and patience then anything is possible.

I still think IMO it would be easier and cheaper to start with a more mod friendly car (240sx comes to mind) that people have already tried things on and there are already answers to problems you will have and more/cheaper parts available if you are wanting to go crazy on a car.

Hope you have Mad surface mount soldering skillz

[gr8scott72]

Hope you have Mad surface mount soldering skillz

On this age of car are they surface mount?

My 95 VW had thru mount chip but then my 00 VW had a surface mount chip. Surface mount chips are a pain to work on.

[yodawill2000]

It may be through mount but I thought I read somewhere it wasn't.

I can do both with ease so I don't worry about it much.

[brandonjustice93J30]

I thought the chip was basically plug and play....

And I can do a bit of soldering...but even so, the person that will give me the look of death for making a purchase of that sort, probally wont let me talk her into letting my buy it anyways...lol

And I dont think I need worse gas milage when it's over $3.00 /gal

After unsoldering the old eprom you would install a socket.

[brandonjustice93J30]

ahhhh....I see said the blind man
