Hey man, Porting the upper is really easy and a great bump with a tune. I ended up porting both upper and lower and port matching the upper to the lower. If you decide to do it, the port matching is imperative to eliminate the lip between manifolds but with the lower - Port the opening (to match the upper port) then blend into stock size by halfway down at the latest otherwise you will lose mid-range torque due to lost airspeed velocity. In the lower half just sand the casting imperfections on the sides. Basically the upper is opened up, matched to the lower but the lower is essentially velocity stacked to keep the airspeed when it hits the head. With the 3" duals and a tune - this is the best intake system for HR/VHR. Trial & error is how I worked it out. Costs very little, just labor & of course a revision tune. You will need a new lower manifold gasket of course and re-torque the lower to head after about 5-10 heat cycles as some bolts/studs can loosen slightly potentially creating a tiny leak that will drop the torque. Good luck brother! P.s. If you don't velocity stack the lower, you might end up with a couple more HP at 7-8k but you will lose about 10ftp between 3-5.5 which is a shame for anything other than redline racing.

Imagine slapping some boost on her when she’s all dialed in it’s all about the curve

[@sleeplessperformance]

Yeah plan is to get it to 11.5 NA then add some boost

[@michaelangelo5783]

What's the $$$$ ballpark to build a fun car like this that can autox or track too? $7-8k? I've seen end of life 350z's for $2,000-3k and local importers have 3.7 for $1,500.

[@sleeplessperformance]

Prices always vary in the used market but it can be done decently cheap if you source 1- a crashed G37s manual and swap it into a 350z. 2- do the work urself.

[@carlitozway9135]

Hey dude. Great time you ran. Question; with the VHR swap, what did you do to get the 350z cluster to work properly with the VHR setup? Sitting with a VHR motor and deciding if I should swap the entire thing or just use the block on my HR heads

[@sleeplessperformance]

So my harness was made to work as a standalone using the stock 370z/G37 Ecu. My chassis does not communicate with the ECU. The speedo works due to sensors in diff. And gas gauge works due to sensor in tank. Everything else I have aftermarket gauges. However there are other companies who make a plug and play harness where everything should work, but they weren’t available when I first did my swap.

[@oep_350z5]

Goals bro dope shit

[@Niitrocide]

Big Congrats car moves. What does it weigh if u don't mind me asking?

[@Supercronic98]

Nice set up ! I was just wondering what size your rear wheels and slicks were ?

[@sleeplessperformance]

15x10 +25 275/50/15 drag radial Mickey Thompson. I now run 26x10.5x15 Hoosier slick

[@Supercronic98]

@@sleeplessperformance thank you so much! Love the videos and look forward to seeing more! Hopefully one day my z will be ready. Thank you 🙏🏻

[@sleeplessperformance]

@@Supercronic98 no problem man any time. Appreciate the support 💪🏻

[@ryanscanlan9875]

Awesome. What lsd & final drive ratio are u using?

[@sleeplessperformance]

Stock 3.5 VSLD

[@ryanscanlan9875]

@@sleeplessperformance the 3.69 vlsd from the 370z is a cheap upgrade that I did but my vlsd is bunk - feels like an open diff. Maybe I'll put in a recond vlsd if they make them. Can't afford a 1.5 way.

[@sleeplessperformance]

@@ryanscanlan9875 sadly I probably won’t do the 3.69 cause I do plan to boost it in the future and think the 3.5 will work better. Plus I already did solid diff bushings 😭😭😭

[@ryanscanlan9875]

@@sleeplessperformance Yeah, solid diff bushings are fantastic. Have you done the trans bushing? & Best luck with boost. Is a dream of mine for sure.

[@sleeplessperformance]

@@ryanscanlan9875 yeah trans and engine mounts have been upgraded as well. And hey man anything is possible 💪🏻

Bro when you were mentioning the bolt on mods & how the car did 11’s without cams etc, you forgot to mention the main thing… YOU..that DRIVER MOD 💪💪

Congrats on the 11 bro. What did the vortech do?

[@Mena6e.c7]

Can g37x launch harder than 2k

[@sleeplessperformance]

Tbh I don’t really know we haven’t messed with many autos

[@anthonydonate9938]

370z shoulda been the 350z with a upgraded interior with the vhr would have sold alot better than it did in europe. 370 are not popular over there but the 350 is

[@sleeplessperformance]

I definitely agree haha I love the 350z chassis

[@anthonydonate9938]

@@sleeplessperformance likewise, what you accomplished with this build just shows how versatile and solid the z33 is, also yours is the only vhr swap ive seen that performs like this. Made yourself a real freak!
