Installing The Best Turbo Upgrade For My 300ZX | Polar Engineering Manifolds!!

Brand New to the Z32 300ZX Market are these beautiful Polar Engineering Turbo Manifolds. To go with these turbos it is a requirement to use one normal and one reverse rotation turbo along with External Wastegates. These manifolds were designed with the 45mm Turbosmart wastegates in mind, which is exactly what i'm installing today! This is set # 003 and to my knowledge the first set to be installed on a motor!
I actually purchased these Pulsar G25-660 Turbos a little over 2 years ago with full intention of going with a externally wastegated setup, before these manifolds were even announced that they were going into production. It just so happened to all come to be at exactly the right time!
This is something the Z32 chassis has been missing for quite some time now as so many other platforms have been utilizing a similar setup for nearly a decade. These manifolds not only look the part, but also open the door to so many more options for turbo and wastegate combinations. This turbo setup in this video I am anticipating to provide much quicker spool than my old gt2871 but also make nearly 400hp more in a smaller package. This platform has always been limited to the typical cookie-cutter, off the shelf turbo kits offered by certain companies. Although it has simply "worked", It has also been the biggest hindrance and limiting factor.
Of course during this install process I will provide my insights and suggestions as I go to make it easier for everyone.
You can place your order for the turbo manifolds here

As for turbo ordering, You can email Polar Engineering for Pulsar or Garrett options.
OR
I bought my pulsar turbos through Moslow Motorsports on Facebook. / moslowmotorsports
Believe me when I say You WILL NOT find a better deal on these turbos then by ordering from one of the two options mentioned above!
Pulsar has changed the name of these turbos to their "5449"

Just to clarify These were not actually 3D printed in steel. Also, Pulsar has changed the name of these turbos from "G25-660" to the "5449" on their site.
Making great progress, beautiful.
Great work. I cannot wait to the final install and test drive.
Another great video. Looking forward to seeing what this engine can do!
Cant wait to see that build done man!!
Well Done, Billy!
Your channel has inspired me to get back into the garage! keep up the good work, can't wait to see how the 300 turns out.
Never owned a 300ZX but have been following Polar Engineering since they showed the rendering of the exhaust manifold. I really want to get the J-Series with a set of mirrored turbos just like what you have for the J-RWD swaps. I’ll likely will have to make the manifolds myself. Already designed the adapter to get a GTR upper intake manifold (basically identical to what you got but with GTR bolt pattern) to bolt to the J-Series lower runners. Your set up is definitely inspiring.
Awesome man!
Billy builds the best
Awesome. Just awesome.
Polar Engineering for the win✅
Can't wait to see it finished and running! Going to start my build this winter. I am looking for solid 400 hp daily usable while modernizing many things as you did!
You can make that on stock turbos with a very broad torque curve. A blast to drive. I had 90' TT with a built engine and stock turbos that made 370hp to the wheels.
@@adeadlyfart13 As I believe that my stock turbos will not be in best shape after 30 years I think I will either replace or rebuild them. Goal is to get boost earlier as I feel the old turbos are hitting pretty late. I will definitely go with a mild setup with "small" turbos 😁
my fn dream build Minus the intake manifold. so much $$$$$
Nice build 👌 iv been running the g25 660s for almost 2 years now on my vg30 300zx very similar spec to yours exept iv got the merlin hi ram and im dbw. With a quite basic tune i made 969hp at around 30psi on 95 pump gas and meth Injection. There's still plenty left in it. Iv just put a built th400 in so will be getting in back on the dyno soon and turning the boost up a bit more. Can't wait to see how yours goes, unfortunately i had to have all my parts custom made for my engine. Its great that polar has started developing the vg30 platform now.
I'm interested to see what kind of power you make through the TH400 with the same settings!
@@Billy_Built I'm guessing about 100hp less. Hopefully not much more lol.
@@Blackbullet_racing should definitely be more controllable power that way. And if you're looking for a fast quarter mile that's definitely the way to go.
Looking great Billy. Its probably just a video angle thing, but it looks like the turbos stick out to the side a little more? Hope you don't have any clearance problems getting the engine in. Also, if I may, how come you decided to keep the hydraulic lifters instead of going with solid lifters? Thanks.
Its goin to low so much te back presure tha limited so much and going ten steps further
Id love to see the spoolig feeling diferecences
Geat video!
gonna need a spacer for your p.s. pulley cause of your trigger wheel bolted into the dampener pulley.
Won't be using a p.s. pulley. -see previous video.
My dream car😖
Do you have any videos of pictures of how you ran the turbo inlet piping. Is it a full 3 inch to the filters? Polar said they were going to make some but i have yet to see them.
I just used regular 2.5 inch piping with a coupler to the turbo.
Can you build same set up engine for my z ?
In theory would the 300zx boost parts fit a vg33? Im building up a prerunner 03 frontier and rather than swap to a v8 i think it would be a nice project to try and build up a nice little motor using the zx bits.
nah. 90% of the DE parts are too different. Although the SOHC motors are pretty strong as well.
Was hoping i could leach off the zx parts in an attempt to save time on fabrication, oh well. Thanks for the reply. Take it easy🤙
Will you be running the Polar Engineering downpipes as well? Recirculating or open dump? Also, would you share the part numbers for the pulsar turbos please. Setup looks sick!
I will be using the polar down pipes with open dump tubes. Pulsar Turbo change the name of their turbos it appears. The g25 660 is actually the same as the 5449 (660hp) turbo
V bands can leak air
Hey billy what are exact specs of pulsar turbos you are running/will be running?
Including AR and what power level are you going for
5449 .72AR 900-1050WHP at 30-34 psi
Turbo link is in description
Hey, are you planning on selling your old ash spec manifolds?
They are already sold!
Hey Billy, been following you for a while here and I’m debating on pulling the trigger on these. I was wondering what the spool up is like with the .72 turbos with the other mods you have or have you not tested yet
Hey thanks! I'm expecting these to spool up pretty quick for a street setup. Especially with the head and cam setup that I have. If you want faster spool up then just get the g25-550 turbos with a .72 ar.
@@Billy_Built thanks a lot. do you think the 500 cams are more worth while than the 400+.
In a side nite, ive been loving your content. Really insightful
@@birdszed for power I'd say the jwt500's in 272 duration is the way to go. But if you're paranoid about having a higher slightly lopy idle than stick to the 400s.
God it took too long, now I have my motor done (and so did 90% of the community).....You also got the downpipes? open or recirculated?
What’s the Horsepower rating on those pulsar turbos ?
@@Davquan37 660 each
@@Billy_Builtwould you run these if your motor wasn’t built ?
@@Davquan37 probably. I don't think it'd be a problem.
@@Billy_Built cool thanks 🙏🏾
What is that dipstick?
