Rebuilding and Modifying a Nissan 350Z - Part 4

[@XxM3TALGUMxX]

06 factory intake is pretty damn well designed from factory. It doesn’t get much better. Nissan really did a great job with the design and under the hood, you’ll see a rubber seal that does not let air leak into the engine compartment. The air has nowhere to go but that small intake hole near the driver side headlight. Factory air box fits right in and all you need is a quality filter.

[@speedacademy]

We're starting to think the same thing!

[@lb9gta307]

Do those aftermarket bumper inserts work as good as they look like they could with the stock intake? I always liked those.

[@XxM3TALGUMxX]

Nicholas Rodrigues they look great! I’m just weary about driving in the rain or even washing the car, I’ve noticed many aftermarket bumpers already have the intake hole molded to it but I’d rather not risk it!

[@VEDEMRACING99]

Never skip on a speed academy video! 👍

[@vongdong10]

You guys finally broke 200K! Congrats!

[@speedacademy]

Thank you!

[@brianschickling6377]

I love that music you guys put in the background at the intro. I want more

[@Lazaralis]

The g35 and 350z forums out there have already did the testing for you on intakes. Stock Z tube is your best bet.

[@josephrizzo7720]

heretic30176 admin tuning has dyno of 35whp gains

[@archangele1]

The stock intake setup takes cold air from in front of the radiator. This is better then any aftermarket unit that has the filter behind the radiator. The idea is to get the coldest air you can into the throttle body and to reduce any restrictions between the filter and the throttle body. . Now, they do make better tubes then the OEM one. I have never witnessed an actual dyno test which showed any appreciable gain in HP from these after market intakes. If there were any gains it was all at the very top end of the RPM band the engine was designed to operate at. I have seen units like on his Z, which had the filter behind the radiator that actually caused the car to loose hp when dyno tested and when the engine was fully warmed up.

[@bradcross2]

dp is so intelligent with his cooling tips

[@Broadizzlz]

i owned a modded 03 350z for many years, best intake mod was the Factory 06 Air-Box conversion with K&N drop in air-filter, along with an Aluminum Z-tube, wrapped the tube in Gold reflective tape. Adding the Plenum spacer to the above, was able to push 278hp at the wheels via ECU tuning. I would have liked to coat the 06 Airbox with heat reflective material and have it tested further...

[@KoreRacing]

I use Mishimoto’s full intake kit and have had zero complaints. Excellent quality and it’s Dyno tested for results. If not theirs I would run the K&N system.

[@ShiftTechPerformance]

like many are suggesting, the factory style intake system works pretty well. The biggest performance gains that can be made in regards to the intake system are with the intake manifold and/or throttle body. Simply adding a plenum spacer will add tons of power. The rev-up lower plenum is designed with short runners that cater to high rpm power, but it kills the low/mid range torque. For the same reason you skipped out on the headers, I'd suggest replacing your lower plenum with a Shift Tech Performance Lower (shameless plug) at the very least, or pick up the set and add a plenum spacer. You will legitimately pick up more WHP with this mod than all other bolt-on mods combined. Plus, it alleviates the oxygen starvation from the front two cylinders, which causes lean conditions with other bolt-on parts. It will also allows for better, more consistent tuning results. You can expect anywhere from 15-35whp realistically, not to mention the difference in throttle response is night and day.

[@speedacademy]

Thanks for the recommendation, wheres a link to your product?

[@ShiftTechPerformance]

shifttechperformance.com/350z-g35-intake-manifold Here is the set (upper and lower). We are offering a few upgraded versions of these with ported necks and plug and play 75mm throttle body which aren't on the site yet. If you guys are interested in anything, or just want advice on anything, feel free to reach out. Contact info in on the site or FB messenger is always up. I specialize in the VQ platform, at least mechanically... So don't ask me about swapping out the factory deck or anything of the sort ;) Btw, I love the content. Keep doing what you are doing!

[@speedacademy]

Got it, thanks for info!

[@ariceff1419]

For the power steering cooler I'd use the most secure fitting that there is for AN connections, I've heard that power steering lines can have thousands of psi in them

[@mrmidnight32]

That rad support is fiberglass btw boys. And the best intake pipe is a charge pipe fed off a nice cool turbo. Must have IMO 😉

[@rubenm1927]

I plan on going with the aFe Magnum Force 2, cold air intake. I like that design better, it has a heat shield and you have easier access to the filter.

[@Theogrn]

You guys forgot to mention the best benefit of Koyo radiator design!, dat clout!

[@willk3807]

Holly shit...i thought I was the only one working on my zed at 3am in my driveway after work. Nice videos guys

[@VS666]

finally pulled the trigger and got some merch. congratz on being the first channel to get my hard earned dollar. this 3in sticker will look legit on my all black fiesta st ;D

[@speedobsession_]

Personally I would return to a stock air box with a K&N drop in filter, Mishimoto air intake hose kit and a bumper intake duct, It won't sound as good but it will have minimal heat soak and you will see no real loss in power especially at the track 👍

[@MrWuWatt]

I just made the same comment, lol.

[@dancarlos1216]

This is the setup I run on a 03 Z for track duty. Next step is heat reflecting tape.

[@TheSergeiFranco]

Ditch the K&N entirely and use stock "paper" filter in stock airbox. But hey in this case it is a drift car so longevity does not matter. The oil based air filters are terrible at filtering and poison the MAF sensor.

[@speedobsession_]

@@TheSergeiFranco that's weird, Never had any issues in the two years my K&N filter has been installed.

[@TheSergeiFranco]

@Speed Obsession, I had been running drop in K&N filter and found that after a few years there was a noticeable build up of fine dust in intake. If filter is over oiled (really easy to do) it will also coat the intake with oil (albeit you have to really over oil it). The MAF sensor is very sensitive to both dust and oil. The K&N says otherwise (of course they do). Even disregarding claims of filtering efficiency or oil contamination, the nature of the oiled filters is that their filtering capacity is smaller then the good "paper" filter. I put quotes around paper because technically they are not paper but synthetic fibre (at least Denso ones are). I would never put K&N or similar filter in my WRX STI, as the factory airbox and filter is not the bottle neck. Provided it only makes 200kW at the four wheels. My other project runs a TRD pod filter (similar to K&N), simply because it is not possible to use factory airbox, nor the factory airbox was of good design (being a car made in `80), interestingly enough that also made 200kW at the four wheels, in this case it is a 3SGTE powered vehicle.

[@TheGCJourney]

I also love going through the Vibrant Performance catalog!

[@logmegadeth72]

Interesting how much you guys loved those crimp style clamps. VW/Audi uses tons of them on hoses and most people hate them with a burning passion and replace with worm gear clamps. But you guys don't have to worry about undoing the clamp since the fitting disconnects at cooler, haha.

[@rat123mumu]

If you are getting a tune go for a 3.5" or 4" CAI and route it into the gap behind the left headlight. Some trimming is needed. Otherwise a 3" will work with the stock MAF housing and can still be routed behind the headlight and into the number space in front of the wheel.

[@supercliff4994]

Check out Z1 Motorsports High Flow intakes for the Z series. They require you to cut a small chunk from the crash bar (yay! more fabbing) but it will clear with your oil cooler, pull in cold air, and clear up space in the engine bay for other mods like catch cans, coolant reservoirs, etc.

[@cajunspecial238]

My favorite Canadians. Love this channel

[@chrishuyler3580]

You don't always have to press your lips together when installing hoses on push-on fittings, but it helps.

[@ChrisDrift]

I've actually not had any issues with the stock power steering cooler on my 350 drift car in a full year of competition, but can never be a bad thing to upgrade it I guess. Oil cooler is definitely a necessity on these cars when drifting though. I'm currently making a twin turbo setup for mine so might actually end up needing another oil cooler as well, but we'll see. Always great to see other people working on these cars though, keep up the great videos.

[@thestigsgermancousin4479]

i like your "secondary intros" ala k240 and drift car build

[@inlinesixrb25]

Man you guys have come a long way.

[@T_Routhless]

I personally run the JWT popcharger intake on my Z, comes with a heat shield and built in velocity stack. Also wrapped the heat shield and intake tube with DEI heat reflective tape.

[@JollyGreenGiant5025]

Nice progress! I use the Vibrant push-lock hose for the oil cooler on my SR swap, and love it. I still might switch over to the braided hose whenever I go to clean things up a little bit. Can't go wrong with their products from what I keep finding.

[@SNAIMAIL43]

DEfinitley get the K&N intake. Installed one on my buddies 350 and it does amazing to seal off heat! Also sounds really nice

[@tomjones5860]

random whistle at 4:50... niccccceee

[@Z33Garage]

Either get a stock airbox ( 06 + ) with the velocity stack, or a Z1 long tube intake. Then Wrap either of them in gold heat reflective tape.

[@pFbSpecV]

Those coolers look good!!

[@octurbojoe]

Did two out of three coolers. Now I need the radiator.

[@AnalogDave]

The injen flows very well. I'd just fabricate a heat shield for it. They are stupid simple to make. I made 2 of them for my VQ35HR.

[@fatb0i33]

Those guys look like two 8 years at Christmas when making those Vibrant lines! Not judging, because I know that I smile when using quality stuff :)

[@speedacademy]

We're thankful Christmas comes more than once a year for us :)

[@PhilJue]

Excited to see this! I actually track my Z but waiting for the season to start :(

[@MrWuWatt]

A light weight Crank pulley really helps with throttle response.

[@jamest5149]

Lemon clips , they are great for fuels systems. Doesn't look like the lemon clip pliers have the side crimp jaw, most do and it aids installation of the clips in hard to reach locations.

[@richardg.4452]

you can also try the aFe power enclosed air intake

[@feelthatfeelthat]

Happy thanksgiving!

[@BobPegram]

Boiling water doesn't let air into the Rad, instead the steam itself is a gas. Gas compresses and liquid doesn't, the cooling system is designed to use incompressible liquid to cool with. As Dave mentioned, lots of nasty things can happen when a gas is mixed with the coolant.

[@thomascanning595]

6:03 Comme ça

[@Mike_Pedals]

I've always been told that you only want to mount an oil cooler with the fittings either on the side or on top. Mounting with the fittings on the bottom can lead to the oil cooler not filling up completely leaving an air cavity at the top, thus not using the entire surface area of the cooler.

[@speedacademy]

That is completely not true. Do a quick search and you'll see companies like Mazda mounted coolers upside down as well as F1 cars.

[@Mike_Pedals]

@@speedacademy yeah I know my rx8 oil coolers are mounted that way.im planning on upgrading them soon though

[@CapeRoadsPOV]

AdminTuning for intake and tune!

[@bloodreighn]

are you fellas going to do the Drift Colorado series ??

[@duomaxwell5807]

Why not mount the oil cooler to the crash bar so there's as much air getting to it while keeping radiator away from the hot air passing through

[@daos3300]

holy crap the state of that radiator at 6:30.. wasn't that a new unit?

[@speedacademy]

That's my bad kept putting the oil cooler in there so it got dinged up.

[@oe2706]

Is your shop in Toronto. If so I'd love to visit.

[@NoNaps_Alex]

I've heard of running the oil cooler upside down like that can lead to bad things. I haven't seen it but, I have heard of it.

[@revolutionday1]

[@Soupie323]

How much total or extra fluid did you use after installing the larger coolers? Oil looks like .65 extra but I can’t find a clear answer on the power steering. Great video! Inspired my upcoming weekend!

[@1elwin]

How is this new design different from the other old one

[@atomicoverridelbc6796]

@speedacademy didn't you guys have the issue getting the Mullet mustang RAD out.

[@snakes5506]

Need to mimic all of your work on the drift z, i think it will be better to purchases a DE better then a VHR... how can i get in contact with the shop for advice on build ?

[@DragoMusivini]

If I was to install an aftermarket radiator like Koyo or an oil or power steering cooler would it throw a code?

[@962RACER]

Not to be a nitprick but when you boil water in the cooling loop you get steam, not air, or am i missing something?

[@rubenm1927]

Those crimp style hose clamps are common on VWs. I hate em because if you ever have to remove the hose you usually destroy the clamp trying to get em loose. Then you have to replace them with another clamp.

[@speedacademy]

Yeah, we knew they'd be awful to remove!

[@SilviaSean]

I would like to see the z33 vs the s14. Did adding the oil and p/s cooler raise the capacity of the oil and p/s fluid? Can't wait to see the z in action!

[@speedacademy]

Yes, part of the benefit of adding coolers is the extra oil capacity.

[@jake77515]

Please be very careful with the oil lines routed that low. Any dirt drops (which happen a lot in drifting) will be super close to those. I flipped my lines on top because I hit mine and pulled my whole oil cooler off. I had a very bad day at the track that weekend. Loving this build BTW!

[@emmanuelmartinez2769]

yup the bottom is always the answer

[@Mk1_Jambo]

Hey guys, cracking content as usual. I’ve currently got a Volkswagen Mk1 Golf of which I’m dropping a re-built 1.8t 20v from an Audi S3 into. Have you ever considered using large bore braided AN lines as water lines? Cheers from London, UK 🇬🇧

[@GasInMyVeins20AE]

VW uses those pinch style clamps all over the place. They're a pain to get off, but they look so clean and are so reliable compared to a screw clamp or something else.

[@The_True_]

The Koyorad/Vibrant recipe with a dash of Mishimoto for cool refreshing consumption! Sweet! At least you didn't have to rear mount and duct in the radiatior with high powered electric cooling fans like formula D cars, that's a pain to do. Great job fellas! ✌😎

[@speedacademy]

Ha! We won't be going down that road just yet :) Thanks for the positive words.

[@The_True_]

@@speedacademy You guy earn the praise! And I didn't go for the "hose" joke because PTs new misses might not like that one. Lol. I hope the married life doesn't mean no more racing! 😨🏁

[@gordowg1wg145]

That may be false logic, as while the coolant has further to travel, there are fewer passages for it to travel through, so the velocity will be higher - this means the actual 'time' for heat exchange may be the greater, the same, or even less than a 'downflow. On the other hand, with side mounted tanks, they will usually take up less frontal area so increase the cooling matrix area. Regardless, always better to over spec' the cooling as you always reduce airflow through it :-) Oops, bit of a potential mistake with the engine oil cooler - with the lines at the bottom there will be little self bleeding and the cooler may be a lot less effective (unless it has a bleed at the top?) than if the hoses were to the top as there is a high probability of air being trapped in the top. Similarly, the power steering cooler should be in at the bottom and out at the top.

[@speedacademy]

The coolant velocity is determined by the pump so that's not the way it would work. As for the oil cooler, many OEMs even F1 has mounted coolers upside down. A quick google search will explain that there is zero issue with mounting it that way.

[@dancarlos1216]

The engine oil is ventilated so the air in the system will be forced through the pcv or catch can.

[@gordowg1wg145]

Volume rather than velocity ;-) The velocity being a function of the flow and CSA it is passing through as the coolant is considered non-compressible - the CSA being the number of tubes times their area and that is why I said "may be the greater, the same, or even less", I don't know their area compared to the OEM. Regardless, definitely an improvement :-) and I like their use of the OEM fan assembly. Re: oil cooler orientation, I may stand to be corrected - this is a direct quote from the MOCAL web site, " Oil coolers may be mounted anyway up and are self bleeding, the resistance to oil flow through the matrix means that tanks will fill up evenly pushing out the air before the oil flows through."; if I ever get round to having a cooler fitted with a bleed, I'll try running it 'upside down' for a while then seeing if there is any trapped air ;-)

[@anomamos9095]

You need to pressure test the heater core to ensure you don’t wear a lap full of steam.

[@Nexium05]

love seeing this drift series!

[@Slowcarfastbeans]

Very Audi-ish. I hate taking those clamps off and sometimes there is not enough clearance to get the crimping tool in to tight areas...worm gear clamps win in those situations.

[@jamest5149]

most crimping tools have two crimp jaws at 90 degrees of each other to aid fitting. Not sure why theirs don't.

[@mas921]

I think subframe rigid collars would be crucial for this drift build IMHO ^_^

Are you gona drill holes in the bumper to improve air flow into the radiators ? Could be a Myth Buster episode. Do holes in the bumper improve cooling or actually hampers the airflow ?
