man thats nice. I guess thats the aps tallboy plenum. I dug around, and i doubt ill be able to find that on used market, but ill keep my eyes open. I cant find a cosworth plenum either. I noticed some of these cool rare parts, are more commonly available if you buy a car with the parts on it.

The kinnetix plenums get alot of hate, but the ogs on reddit are over there praising the velocity manifold, w dyno numbers. They said the velocity manifold got a bad wrap because of the ssv, and all the other horrible plenums they put out. They claim that if you just inspect the iffy build quality, the velocity manifold does numbers, even on a NA Z.

 

Yep. I had a lot of time and effort in that car. Sometimes I think I should've kept it and installed the JWT S7 cams I had bought for it, but I have car ADD. I get bored and trade out cars every few months to 3 years. 3 years is the longest I've owned a car. Had the Z from '06 to '09. Traded it in on a Mustang. Shortest time I've owned a car was 27 days.

 

it sounds so sad lol. Im kind of the opposite, i just have lost my cars in past somehow. I get attached, want to keep them if they're sporty.

They do make a soho manifold of some sort, that looks like a plenum. Im glad theres still some aftermarket support, for the 350z.

 

Smh. Getting yourself 8k deep over a money pit. You could have found a proper Z for way cheaper than you got yourself into.

 

All to be shook apart by not having a harmonic damper

 

Not to mention Thanksgiving in a couple of days.

 

i looked it up, but am low knowledge, feel free to explain


I promise you all if this threads open for next Thanksgiving, ill make a Dugan day tribute run. video 2024. Even if i have to bump the thread.

You all are definitely correct, i should have saved money and bought a diff car. ive seen some nice 40k dollar builds for 20k its sickening. Im in it now.

 

Correct or not, the problem wasn't deciding to build up this car. The problem is buying unnecessary and unnecessarily high priced parts. And on credit at that. But in the end, it's your car and while the majority here likely wouldn't support your approach to building a car, well, no matter. As said, "it's your car".

 

Quick - set the time machine back to nine months ago!

Nah - that wouldn't have made a difference.

But will OP listen to us moving forward?

 

Does anyone really know what time it is?
Does anyone.....

 

OP has less than 24 hours for a full part out, buy a properly running Z, and make the acquaintance of a pole...

 

• When the engine’s cylinders fire (which happens THOUSANDS of times per minute), it creates a whole heck of a lot of vibration and torsional distortion to the crankshaft.
  • Torsional distortion is a fancy engineering way of saying twisting back and forth.
• The harmonic balancer absorbs all of that intense vibration and offsets the torsional distortion to protect the crankshaft, and ultimately, the engine.

My 350z came with an aluminum crank pulley when I bought it and one of the first things I did was purchase an oem pulley to replace it.

 

I musta missed that little fact but then, this is an "entertainment value only" thread so not paying that much attention.

No harmonic balancer?

Good lawd.

But at least it's not a big four banger.

 

lol u all got me hella confused now. i guess ill have to pour over even more research on the topic. It seems like mic may disagree, so ill just disregard the harmonic balancer thing, until i decide its important. I got the two z1 pulley kits. light weight crank pulley, and serpentine drive belt. It came with some oem looking pulleys.

Well, Ive seen some wicked cars for sale. I used to never use facebook and im in groups, with built cars for sale etc. I saw a s14.5 for sale it said. Full padded cage, ls swap, car had been stripped down to chassis and every part painted and gone thru. All kinds of aftermarket parts. Power was in mid 300's, and can be turned up. He said it weighs 2600 lbs wet. 22k dollars, no ac or air bags and stuff. Its probably safer and, fast as hell with that weight. It also came with a bunch of parts! Cd009 trans and two r200 diffs. And i could have beat around town in anything.

Im also still eyeing this FBO hr, thats been babied to hell, with 50k miles. Its got a sound system, custom blue interior accents, z1 built r200 diff. Everything has been done except build, or boost. The bushings are changed. He has the z1 arms you have to take off to adjust. It has a tune, everything. 20k and he wont budge. I think with the extensive parts list i like, its worth it.

I could have got cheaper parts, but i do want what i want, and I still think buying that S14, wouldve made me way happier than building a z thats all screwed up and was 10k lol. Its interesting how i wanted the tomei for the sound/performance. Then i got it, and hated the sound til u get above 3k or so rpms. While i loved the sound at top end, i got pulled over again and warning for sound, and a little slide for turning left when it turned green. The cop was ahead of me and just heard it. Its like a cop beacon, and my neighbors are all grumpy. I dont like it for around town anymore.

 

 

So the damper thing... The VQ has a harmonic damper that quells high frequency vibrations that can damage main bearing over the very long term. It's not a balancer. The VQ is internally balanced. You can run an underdrive and have zero problems for over 100k miles. Now, if you get a misfire and don't fix it, not only can it destroy you cats, but it can also introduce some odd harmonics that would normally be damped out by the damper. This is where not having a damper can hurt you. As long as your engine is running fine, and is not boosted, it's rare that the lack of a damper will cause problems. Boost introduces odd harmonics as well. Back in the day, Fluidamper made both underdriven and stock diameter crank pulleys. These would be what I'd run if I was building a boosted motor. On my '06 I had a non-damped aluminum underdrive crank pulley and an overdriven alternator pulley to compensate. The resulted in just the A/C and P/S being underdriven. I never had a problem, but I only had my car up to about 30k miles when I traded it in.

 

awesome thanks for the info! i think i got most of it, im over here trying to figure out was a/c p/s means now. edit: got it, you mean the air conditioning and power steering belts.

 

Harmonic damper/balancer are used synonymously.
Yes, it is of low risk to remove, but why risk at all for insignificant gains?
Albero had dynoed the UR pulley back in 2004 and saw a tenth of a HP gain

 

If you use them synonymously, you're using them incorrectly. They are different things. There are engines that are externally balanced and engines that are internally balanced. It's important to know which you have if you want to use an aluminum under drive pulley. I got 7 whp from mine. I know I posted the dyno online. It was probably here. I posted dynos for almost every mod I did. If you're worried about it, like I said, Fluiddamper made a damped under drive. I honestly don't think the underdrive was worth much HP, it was probably the reduction in weight going to the aluminum. Horsepower is Force times distance divided by time. So, anything that allows it to rev quicker will increase horsepower. As far as it being worth it, I don't keep my cars for 100k miles, so yes.

 

Lol, so trans exhaust +, is scheduled way out in January now, but it's on my shops schedule. I still need financial recovery. I hit a bump last night, and it did something to my acceleration 😐. I looked under the car, in attempt to figure it out. All i could see wrong, was my plastic undershroud was sitting pretty crappy. It was all zip ties except two screws.. Im wondering if maybe it slapped a belt. I removed it. I can put an undershroud on. I have the z1 one. I dont want it to get crappy being removed by shop for trans, i figure one install is better than two. I may ride without one for a month and a half. Im also considering putting it on myself, I wonder if it would even help the engine much heat wise (warming up quicker on cold mornings).

So, this is coming to a head. ill have the ported stuff and belts. Ill even have coilpacks. The car is officially using exactly about 2 qts of oil per 4k miles. I may not put all of this stuff on, and i may rebuild the engine first. Im either going to jump straight into it on a no interest credit card; or jump in another z or car, and barely drive it. But I will still plan to rebuild the engine someday.
