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
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
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
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 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.
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!
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.
@@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.
@@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?
2 years late but if he had a LD28 3.1 stroke he can possibly make more power not sure piston size probably 87mm or 89mm ? But its been done before 500 horsepower and border line 600 horsepower especially with 1000cc and an OS Giken Diff and rear axles he can even use a 370z diff the 240z all the way to 280zx diffs hates 300 to 600 horsepower especially the RB or LS or 2j and even L28 turbo swaps so most folks do this diff swap i think theres kits for it as well also theres a 350z tranny adapter plate for L26 and L28 engines . Why a 370z diff ... because my uncles 2jz 240z oem diff left the chat on him know what i think your customer is good where hes at lol
