Shawn's Turbo 280Z Dyno - New Turbo Manifold made how big of a difference?

We finish up some tuning on Shawn's 1977 280Z. The car is running an MS2 PNP standalone, 550cc injectors, $130 eBay turbo, and a Godzilla Raceworks manifold.
After fixing a few issues with the setup, we now have it starting and idling well, and making decent power even though we are currently distributor limited to 21* of timing.
Previously the car made about 190whp on 13psi. Now. With the new exhaust manifold setup and 3* exhaust, we were able to make about 200whp at only 9psi. Once the boost controller is wired up, we will shoot for more!

Hey nice parts :) Thanks again for the business!!

[@Triplenickelmotorsports]

Thanks for this... it's good to see Shawn's hard work coming together with lots of help from you guys.

[@DyNomadMobileTuning]

He's done a great job with it! Glad to help where we can 🤙

[@eddieace345]

any way to get in contact with Shawn. I also have the an L28ET and wanted to pick his brain about turbo and how he connected the vac lines on his protunerz manifold. I have the V1 manifold from them with their fuel rail

Would love to see an update on this Datsun 280z. This video gives me hope for mine+

[@denzellrocha5313]

Sheesh, that pull @6:10 is 10 pounds?!??!???! I gotta finish my Datsun turbo project, thanks for the excitement! Dang this makes me so itchy!!!!!

[@itseric1jzson]

Man that 280z sounds so nice

[@dreamchasers5577]

so happy for u guys man super knowledgeable keep pushing💪💪

[@DyNomadMobileTuning]

Thank you!

[@MindDezign]

Great job, that light weight Z scoots better now!

[@TheEdwardacevedo1]

I need to get my swap finished 😅 also have an L28ET in my 240Z but too lazy to wire it up

[@madisonedwards4411]

Has a dyno Still loves to street tune for that final finesse lmao You can take the racer our of the streets but you can't take the streets out of the racer

[@DyNomadMobileTuning]

Haha you know it!

[@Sickstringfarm]

Wicked sounds!

[@TheSaturnV]

Luv the wheels and the hood flag.

[@winstonpratt604]

My buddy had a 71 240 with a Arizona Zcar intake and a 4barrel Holley 394 with a single 2.5" Flowmaster 40 series it sounded like a 500hp beast but just had flat tops and made about 225

[@Icepacalapse]

Stock F54/P90 with non-turbo flattops made same HP at 7.5 pounds of boost in my car on a dyno dynamics dream crusher.

[@cashtalks6253]

I have been wondering if you put a compound turbo set up using a electric turbo first then one off the exhaust. I’m poor so I can’t try my ideas but I have a 76 280z that I hope to build one day and want to build it to make lots of power and add new ideas I have as far a power and body mods that’s not what everyone has done.

[@shalomsda1861]

Hello can you help what kind turbo you use and the manifold conversion you use it?

[@winstonpratt604]

Definitely one of the sexiest platforms ever made period 😂😊

[@04boogie-t14]

What’s the exhaust set up?

[@cashtalks6253]

I’m building a 280 z what can you tell me to help out when I get to building the motor

[@JustAnotherAsianGuy2]

cool

[@kaedeschulz5422]

Love the sound of the L series😍 Those wheels are perfect! What rims are those? Yet i wonder.. shouldn't an L28 be able to make 400+hp? I guess those builds also rev up way higher.

[@winstonpratt604]

It's hard to push the L series over 350 imo

[@kaedeschulz5422]

@@winstonpratt604 It's hard maybe. It's doable so i don't mind putting in what it takes if i ever have the chance to get a Z. Sice i know the Z Speed Shop Shinohara has built in the 90s it's my dream car :D Even if it would take years to build that engine it's worth it to me.

[@That260z]

​@winstonpratt604 It's not that hard to make 350rwhp I've heard of all out turbo l28 builds making 600 to 700 horse power.

[@kaedeschulz5422]

@@That260z And that's in tha 80s and 90s.. On carburettors too!😵😁😎👌

[@TurbineResearch]

Needs some coil packs and it would be 😎

[@DyNomadMobileTuning]

Yes it does, we could gain full control of the ignition map with that and make a noticeable difference in power and driveability. Couple that with a nicer turbo and he would be in there!

[@Triplenickelmotorsports]

that is next phase, just need to add a few things before that.

[@kaybevang536]

Carburetor or fuel injection?

[@sekcgamer7623]

Fuel injection all the way!

[@Thughes97]

Any updates on this? Would love to see current numbers after once the boost controller is on

[@skirkland1980]

I'd be interested to see how much whp it makes with stock manifolds. You're down about 40-50hp over stock manifolds.

[@manworksgarage]

????A stock 280zx turbo makes 180 engine hp. This is 205 at wheels. Low boost.

[@skirkland1980]

Yes it's down on hp.

[@SidewaysGts]

@@skirkland1980 "Yes it's down on hp" Just to clarify- Youre saying it "should" be at roughly 250~ whp on 9 psi?

[@skirkland1980]

@@SidewaysGts Yes. I'm curious what the intake runner ID is. I'm assuming it's 1.5". The intake port is 1.375". A mismatch like that can cause low hp numbers. For reference mine is almost exactly the same combo with just a bigger cam and makes 465whp @23psi boost through an auto trans and very loose converter. Also made 280whp with a completely stock L28et, ebay turbo @ like 12psi.

[@SidewaysGts]

@@skirkland1980 "For reference mine is almost exactly the same combo with just a bigger cam and makes 465whp @23psi boost" Would you be willing to share your exact set up and what kind of dyno this was on?

[@phantonamor]

anyone know those wheels

[@OakleyOptions]

Rota TBT

[@sekcgamer7623]

Damn I making 303hp/308tq on 6lbs of boost on my l28 made into an ET.

[@denzellrocha5313]

High compression?

[@jonathanmcollins4]

We need more details on 303hp at 6 lbs! What cam, flat top pistons with a P90 head, ported? What turbo, injectors? Can we get an ignition table?

[@fetusness]

Sheesh
