Those are direct injection, so it's not quite apples to apples. They can get away with higher compression and leaner afrs.

Here is the video when I road in the JUN z34 last year when I visited JUN headquarters. The car has the same cams and compression setup and mind you is untuned. Listen to when the driver steps on it. The pulled hard and idled normal. Again it's untuned this is what you car should sound like.

if the civic guys and SBC's can run 12:1 on 91 and 93 im sure our motor can too. Being that it was tuned in germany they most likely used 98 or 100 ron fuel. Also we have better tuners for the vq here as well, i would bet the vvel on that car was untuned.

If cams pistons and rods could really get us to 350+whp on 91 pump gas, it'd be pretty tempting depending on the costs.

So to recap from those who know, to install the cams correctly, you would need rods and pistons as well? Anything else? Does anyone have links to the pistons and rods that would go with the cams? Just curious as to cost.

CTD-GERMANY have what u ask 👍 or go with jun they have stroker kit and cam

Im using 93 octane and 5w30 red line oil with mods and cam i hit 361.4 whp before tune and now with tune have 378.6 whp. Yestrday night

My proplem solve with vvel rest

Thank you navyboy918 and cdoxb800

that's great! you are still running all standard gear?

do you have dyno results of before and after you can post up please? would love to see the tuned dyno graph.

If the dyno is legit he is the new NA king. Sorry mike the powdercoater :O

Also, I'm pretty sure more ppl will go that route if the price is right for all the parts

Ive been on the jun website before and all they have for sale for the 370z is the cams and a bigger throttle body. I think their stroker kit is a prototype and not for sale yet

Even if he is at 378 we still don't have a baseline. Alot of information not on the table.

Great job! Glad the vvel reset got you back in track.

A baseline is good to see by how much those mods increase power but at then end if he's pushing 378 those are great results

You gotta be the stateside beta tester for this bro.
I missed my chance while my engine was out because there was no evidence or reasoning as to this mod working. But time to man up! :p

Elia, what were your trq numbers? Can you post your dyno sheet?

Maybe, trying to figure out hat I would need and how much actual cost would be.

Although navyboy is the real beta, he's just not done yet.

No problem glad you were able to get it corrected.

Jun themselves only claim 15-20whp gains from the cams which is why anything more than that is hard to believe without other supporting mods. We all know manufacturers usually post optimistic gains. That's a big thing holding me back from trying the cams unless there are some supporting mods that make some of these high numbers easier to have confidence in.

Thats 15-20 hp with no other mods. When I visited JUN they said that the cams were made to be used with stock everything even stock air boxes. To me that's pretty good

well i've got do my headgaskets how much are these lol, you don't need pistons and rods unless the cams hit the pistons which these don't you need cams, and when they are being put in you need to have them shimmed with different thickness lifters from nissan to reset the clearance to the cam, and tuned.

Lol don't need a tune. Is made to run on stock program. Again glad to hear your VVEL reset did the trick.

When a manufacturer says 15-20, you're probably looking at more like 10-15. At probably 2.5k including labor, that's tough to justify. Is there anything else that can be done for gains while in there to make it more worthwhile overall? This is a general question out there too all you guys who know a lot more than I do (which isn't very much).

Well, Jun's dyno was a joke. It was on a 3.7 vs 3.8 or something and 91 vs 100 octane

yeah, I don't trust it or the German one either. Too much unknown info which is why I am just going by the real world estimates (manufacturer advertised numbers minus 5). 2. for 10-15who is a tough pill to swallow which is why I am asking more knowledgeable forum members if there's anything to do while in there to make the overall package more enticing, like maybe 25whp gian for 3k or close to that.

Sorry sir In my country is hard to get dyno sheet without paid 70 dollar = 20 KD in my country . only get result from dyno screen

The trq is hard to get high without F.I and my result is only 279.4 and after 293

The change is big on street mybe later i show u a race vs muscle car to aproved

My new mode is : OBX LTH , ARK CBE , aem long tube air filter , 320 lph fuel , M370 manifold , universal oil cooler , stillen pulley , spec ss twin clutch W flywheel , jun cams and thermestat .. And 93 octene with 5w30 red line oil

290 is great for NA trq. We're not expecting boosted trq numbers.

You a man 😂👍

And thank u again , and dont try it beacuse the money will gone like a train , i wasted 3k with cams , 1.5k for install and 800 for cam sensor

5.2k + 1k = twin turbo

Thats make me cry to make only 30 whp 25 trq

This is a interesting thread. You even used Obx LTH. Do you have any videos? Idle change at all?

only 30 and 25? Are you saying your baseline before the cams/tune was 348whp?

Also, 6.2k is nowhere near enough for twin turbo. with labor and supporting mods, TT done right will be more like 15k if not more.

The Cam cost you $3,000?

I've priced out cams plus install at about $2500 over here. Super labor intensive.

damn! $70 for someone to hit "print"? thats nuts:nutswinger:

Yes its cost 3k and dollar

Im order it from jun japan and our country gets funds from customs ,, the life is hard here 😐

Iam from middle east not from eur or us

I agree with u

But from emirate u can get orginal power house amuse only for 3.8k with spoiler

The proplem is in emirate or bahrin or oman is hard to get cam or pistons

ouch!

Its pretty cool to see someone finnaly post some numbers with jun cams, I'm a real big fan of n/a power 370ish whp is pretty impressive an it seems like the car is still real streetable. An I'm sure the car feels/is real snapy with the high comp pistons. can't wait to see a video of your car, props man

Holy ****.

I would totally do this if the gains were really 30whp and 25trq, but Jun only advertised 15-20.
