Choosing vortech over turbo. What do you guys think of my plan?
 

Well... i was going to turbo my 06 Z. But now my living expenses are a little higher, and I genuinly think it's just wiser to go with the supercharger...

I plan to get the V3 tuner kit as well as a 255lph Walbro fuel pump, 440cc injectors, and an Osiris tune. And yes I know, get a smaller pulley. I know. Am I missing anything of huge importance? I don't believe I am from what reaserch I've done. While I'm here I may as well ask for a rough guesstimate of installation cost for it all. I don't have the time or the know how (yet anyways) to do it on my own.

Thanks guys.

It will cost about the same for a used turbo as it will for a used supercharger. Turbo will allow you alot more flexibility. If i could do it all over i would have went with turbos over my procharger.

nobody will know install cost, it will vary on alot of things. i just have to leave this here

😂😂😂 Okay, okay. I get the point. But everyone has to start somewhere. Just askin' for a little advice is all.

i know, and just giving ya a little hell.

Pretty sure anyone with basic tools could install a vortech

Add fuel return, gauges, is it neccesary to get better fuel rails? I haven't found anything about that...

Same with a turbo kit...


Tuning it, that's a different story but just about anyone should be able to set up and bolt together a T kit and supporting mods.

Stage 0 Fuel return fuel systems should be enough for about 450 rwhp. For a stock block do dont want to go higher anyway (420-450 flywheel hp is still safe). Piston rods wont hold that for long.
I would also add a oil cooler. And if you want to race a bigger radiator.

Ive been pushing 438whp on a vortech setup and a fuel return system is definitely not necessary yet.

And to OP, 440cc injectors will be small, I suggest just make the switch to 600cc injectors so your injectors aren't at max duty cycle

Agreed 600 will give you more headroom to work with.
That 438 wheel hp you have is that maxing out the blower? (i guess you have a V3 SCI kit?)
Do you have supporting mods?

The blower is maxed out RPM-wise according to Vortech (Although they underrate everything they sell).

My current setup includes:
Vortech V2 head unit with custom intake
2.87 drive pulley
walbro 255 fuel pump
OEM GTR injectors (~550cc and they are VERY close to being maxed)
Full exhaust
Kinetix Velocity intake manifold

Good to know. I will opt for 1000cc ID then. Im aiming at 500 rwhp. (build bottom)

With a 2.87 pully you are already slightly overdriving the SC at max shift rpm (6600rpm)
If i put everything in the calculator i get 54.554 rpm (http://www.vortechsuperchargers.com/page.php?id=33511)

I run my V2 SC-Trim at about 62,000 rpm with not problems over 40,000 miles.

Damm thats way over over limit. With stock bearings? Does it keep creating boost over 52.000 rpm?
Or do you spin it that high so you have a better pickup in the midrange.

Guess it makes quite some noice when the engine is idle :D
Also enplanes your ability to hit over 500 rwhp.

The Limit is just a number Vortech came up with.

Yes, stock bearing

Makes Boost to RedLine 7100 rpm, a bit over 19 psi

It's quieter at Idle because you are not getting the back Lash in the Gears with the Supercharger runs slow.

Good to know they handle overdrive well.
Do you have different cams and springs for 7100 rpm? i was thinking about bumping my rev limit of my revup to 7200 (only 200 more) but leaving heads stock. Or i can just go for a 3.13 stock pully with the Ati damper and spin everything at 58k (V2 Ti blower is rated at 55K rpm. But i dont know if i will get to much boost then)
That 19 PSI after the intercooler / before plenum?

Oh thats nice :D

I have a 2003 350z touring. The Motor is completely stock never touched.

19 psi is at the Plenum.

My sign have most of the basic info in it.

Your build is very impressive, sir. 19psi on a stock motor is insane. Been reading alot of members that believe 400hp on stock rods are the limit, or that we need to stay under 400tq to make a stock motor last, but here you are years and Thousands of tested miles and drags will almost 600whp on your best tune. I can see now that the tuning the right way is soo important. I hope to be able to tune my car as good as you one day, I'm still learning but still have more work on my tune to be done to make big, consistent and most of all, reliable power.

Wow thats inpressive.
I have seen so many people blow there motor at 450+ HP levels. Rods bend and stuff like that. Its impressive that your motor is able to hold why higher HP levels without problems.
