Call me a ridiculous idiot if you'd like, it was just a thought

I'm not absolutely for certain, but the VQ40DE is close to the engine in the 350/370Z, right?

What do you guys think the possibility of getting the 350/370Z dual turbo system transplanted into one of our frontiers/xterras is?

I know it's very possible with STS remote turbo systems, but I'm curious to know if the turbo system in the Z's is possibly an EASIER approach...

There's a guy on the boards here that installed the STS based system in his xterra and at 10lb of boost, he was getting 430HP to the wheels, and 500hp at the crank, all stock engine internals, no problems at all, crazy-cool.

thanks

I think you need to read more about XterraHines Xterra. He just posted a week or two ago that his motor blew. One of his pistons cracked or something.

Now for a TT transplant from a 350/370z system is possible. the one thing that holds most back is our intakes. The Z runs a dual TBs for the most part so that screws us. Others do run single but then our limiting factor is the intake manifold. Yes, the Z has an option out there for a metal one but our head design doesn't allow this to be used for us.

Now I have to ask, are you looking for top end power or low end? If low end, then you are looking in the wrong place.

No And He Already Hurt The Engine. Ive Already Looked Into It With The Guys At Engine Logics Here In Houston. The Closest And Best Kit In This Regards To Start With Is The Twin Tittie Setup From Greddy For The G35. @$6k. Plus Fab Work To Get Around Several Issues Like Water Pipeing And Intake, All Can Be Done But Just Adds To The $$$$.
The Universal Single Tittie Kit From Sts Starts @$2k, Less Issues With Moving Stuff Around In The Engine Compartment And Cheaper..and What The Hell Are You Starting This Thread For When Youre Trying To Sell Your Pentax Lense Cause You Need Money
Unless Its Money For A Turbo Setup

you'd be much much better off just going sts, the reason the the kits for the Zs cost what they do is because your paying for a system that was designed to be easy bolt on for a z but that wont be the case on a frontier so if your going to have a bunch of custom work ahead of you you may as well save a little cash and go the easy route and make a system similar to xterrahines did

370z is a different engine. 350z is close...but I don't remember which block the 350z used that is similar to the 4.0 we have...


Even then, turbo's are most effective at higher RPM's...which this truck doesn't really carry a lot of. The VQ37VHR in the 370z has a 7.5K redline - a bit higher with the nismo version (just an ECU flash...) - not something I'd want the longer stroke of the 4.0 Frontier engine being subjected to.

Another thing is that high HP means nothing when it's at 6.5K - give me 300lbs of torque at 2K, and now we're talking.

your a little off on a couple things, turbos are very effective in low and mid range if you want them to be. you just have to size your turbo for your application, there are more than plenty 6k rpm vehicles that run very good turbo set ups. and now with the tech that is going into turbos its very easy to have a turbo hit full boost before 3k rpm and make very good power all the way to redline. its not really that turbos are most effective at high rpms but that they continue to be efficient to high rpms. the 03-05.5 350z had a redline of 6500 and the guys running turbos are putting down much better times than the guys running the supercharger set ups. your off on the nismos a bit too just to throw that out there, both nismo and non nismo 370z have a redline of 7500 the difference is the nismo makes peak power at 7400 (350 hp) and the non nismos make peak at 7000 (332 hp). lets also not forget that if you build the motor you can go up to 4.5L with this block on a turbo set up and turn 8k rpm no problem. most guys with Zs running twin turbo set ups like i did had to adjust the boost down at low rpms to that you could get a good 60f time on street tires or DRs without spinning your nuts off (gotta love electronic boost controllers) just saying man, not trying to come across as a d bag but its pretty easy to toss out that argument.

you'd be better off spending 7-8k on a used E36 M3 and get a lot more out of it imo

stroke of a 4.0 is longer than a 3.5.BUT thats nothing with the right parts. Now a 4.5" stroke crank. thats alot of stroke on my 580 and that gets turned to a redline of 8k. I can tell you offroad, I hadly ever get into boost and when I do, Im at redline(my redline is 7800rpm. But that like hill climbing not rock crawling. Around town Im still like launching an 18 wheeler due to weight. And my boost with the Eaton would be setup the same as a turbo. But the turbo will continue to pull hard to redline(I drop off before alot) and uses nothing in HP compared to the blower to turn at boost. This is why Im looking into compound forced induction, use what Ive got and add to it with a turbo....But alas Ive got alot on my table(forget the plate that ran over years ago )

should buy a diesel then haha. I was looking into this setup as well, I think it would be cool to have a VQ40DETT under the hood. two little humps in the hood, people would write it off as a truck and its slow until they hear it spool haha.

I want mine to be at full boost when our CVTCS kicks in on our Intake size.... as if its just taking a deep breathe haha

CVTCS? Are you talking about the VIAS?

If money isnt an issue, supercharged VQ56 is the way to go.

Dang, that would be a huge bore on the VQ40, lol.

I assume you ment the VK56 from the Titan or QX56 and yes, that is my final plan for my truck. A stock VK56 to start and make sure everything is happen then a built blown VK56.

 

[Militia]

haha yeah thats what i meant VK not VQ
