moding stock 300zx

[devinarney1]

So i have a stock 92 300zx and im looking to boost my power a bit. What modifications could i do that aren't outrageously expensive?

[redneck zx]

are you tt or n/a?
pop charger(intake) jwt
egr delete
cats

[xclusivez32]

headers, catback, underdrive pulleys

[a.p.barron]

Intake
Headers
Exhaust
UD Pulleys
ECU
Lightened Flywheel
Lightened Driveshaft
Miscellaneous Weight Loss

If you don't have the hookup, and you do the labor yourself, all that stuff will cost you like $3,000, and you'll get somewhere along the lines of 30 - 40 rwhp, assuming you have an N/A. Someone correct me if I'm wrong.

[devinarney1]

Im assuming tt stands for twin turbo. Nah its non turbo. Yea so is a popcharger like a k&n air kit? And what would be some recommended exhaust systems and where could i get one?

[es.biggs]

my favorite exhausts are Specialty Z and B&B

Popcharger is basically an air filter, K&N style cone type

Some popular online vendors I use a lot:
importpartspro.com
z1motorsports.com
specialtyz.com
courtesyparts.com

an NA doesnt have much potential power wise. you can dump a few grand in the car and not have much in the way of increased performance. if you have the need for speed, id consider selling it and buying a tt. otherwise just enjoy it, imo.

[es.biggs]

That's true. Nothing wrong with an NA, but no matter how bad you want to be fast, you won't be unless you have a lot of time and money lol. They are quick, but by today's standards with modern cars, they are not fast.

But I still enjoy mine every time I drive it

[devinarney1]

Thanks everyone for your suggestions. Yea im not expecting my NA to put out any crazy hp. All i wanted was to do a few modifications to make it a lil bit faster. And who knows mabye someday ill get a tt.

[car nut]

With bolt ons I was able to get my NA another ~90hp and ~100lb/ft of torque.

[txQ45]

Tuning for E85 is suppose to give more HP to high compression engines..
See how many are around you www.E85fuel.com

Bolt ons? What do you mean?

[Z31toZ32]

yeah he has i believe a v8 swap in his car.

V8 swap eh? That's interesting. I didn't know you could do that.

[es.biggs]

Yeah it's a pretty sweet mod for us NA guys LOL

[devinarney1]

what kind of v8 would you put in it? just anything that fits or is it something made for z's?

[a.p.barron]

Pretty much anything will fit under there with enough modification. From what I've seen, the most popular V8 swaps seem to be small block Chevys, like the LS1, or Nissan's Vh45DE. People have also swapped Nissan's RB series engines, SR series, and even the KA series.

Sounds pretty cool. Pretty expensive to. Z's are not cheap to work on!

[grk nickafis]

If you are looking to keep the VG30DE,

-delete you're unwanted vacuum lines and EGR.
-Headers.
-high flow cats (or test pipes but you'll lose back pressure).
-Cat back.
-Pop Charger.
Bigger Injectors.
Upgrade Fuel Pump and FPR.
Light Weight Flywheel.
Light Drive Shaft.
-ECU upgrade with EPROM.
-Fully Pulley Kit.
-New Motor/trans/Subframe Mounts (Solid is the best).
-Delete Air Condition.
Delete Clutch Fan (Get E-Fan).
-Short Shifter with Bronze Bushings.
Strut Tower Braces (Strut Bars)

Thats about all I could think of right now. At least thats MY plan haha I have most of this stuff already for under 2 grand. Everything with a - i have.

[a.p.barron]

Oh, I forgot to mention something, and surprisingly, so did everyone else. Before you do any modifications to your car, you should give it a really good tune up. You'd be amazed at what a nice tune up can do. If you think about it, what's the point of doing all of these mods if your car is running like garbage in the first place?

[grk nickafis]

i always thought the tune up was implied. Its just what you do when you have a car. It deff cant hurt so go ahead. I just blew my engine about 15 minutes ago so i have nothing to tune up but I was due for an oil change.

[a.p.barron]

You would think it would be implied, but it's surprising how many people don't do it. I get the feeling that oil change comment was a littile sarcastic, but don't underestimate the power of a nice oil change.

[grk nickafis]

haha no im serious. Cylinder 1 and 5 dont fire anymore and im wondering if its because of my oil. Someone told me my spark plugs are "fouled" ... idk tho.

i did the LS1 Turbocharged swap in my 94 N/A, great cars extremly fast when done right. All i put on my N/A before the LS1 swap was an intake, headers, exhaust, lightened it, and put a one piece driveshaft in. It would eat most of the common cars you would see on the road.

a turbocharged v8? do you have a dyno sheet? i'm sorry if i sound incredulous, but a turbocharged v8? the v8 by itself is plenty fast as it is.

you put on an intake, headers, exhaust, lightened it, and put on a one-piece driveshaft too...before the v8...but you're asking what mods to put on your na to get some more horsepower (in the other thread)? proof, please.

[bigbumpinZ]

ill post some, just gotta find a camera ha. my N/A in my other thread is my newest project and everyone one was like keep it an N/A and drive it daily due to the fact an LS1 sucks with gas miledge. all the upgrade on the N/A before the LS1 swap were because i didnt have an LS1 engine to swap so i just wanted to get a few extra hp, but one of my friends wrecked a turboed Vett so i bought the engine off him and procceded to do the swap. Not easy by any means. but pics will be up shortly

understood, which is why i thought it was weird you were asking what upgrades/modifications to put on your na when you already knew, from your first na, you had listed the parts you put on.

[grk nickafis]

update- Oil didnt foul my plugs it was the PTU. I'm running no AC and no Power Steering now... i hate it... no AC doesnt matter bc its 30 degrees in NJ lately but power steering isnt worth it to delete... good thing i only took out the belt and not more. No power gain anyway...

So one peice driveshaft makes a big difference?

[bigbumpinZ]

one piece drive shaft can add power if you get a lighter one like the ones at z1 there aluminum correct me if im wrong, also getting a one piece drive shaft eliminates the center carrier bearing

[a.p.barron]

It's not so much that it adds power, but it definitely frees up some. If you get a lighter one, the engine doesn't have to work as hard, which should make your car more responsive. It's the same idea as getting an UD pulley, a lighter flywheel, or lighter rims.
