APS single turbo, want to build motor
Hey guys, iv been driving my Z for about 2 years now on stock internals and the APS single turbo kit with the GTM single upgrade kit (pretty much throws a true GT35R on it)...since I upgraded, the car runs WAY better (made 408whp on stock internals and the stock tune on the unichip)...there has been zero tuning work on the car...it runs great, I run it how it should be and have daily driven it for 2 years...but since I did the upgrade kit, I havnt been able to run a filter because there just isn't any room to run an intake...it does have a screen covering it...but I'm scared that's just not enough..
My question for you guys is, what should I do?? I want to buy a built short block (looking at forged performance) but is it worth it...I'm going to have to figure out some sort of intake...
Or should I just keep saving for a 2jz swap?...2j swaps going to cost somewhere close to 10grand after single turbo and tuning...

Can you change the intake piping so that you can locate the intake in a location where you can use a filter? If so, I would look at doing this.
If you are going to go through the trouble of doing a swap (it is a lot of work), I would look at a swap to an LS3 motor. As the saying goes, there is no replacement for displacement. And, the LS3 only weighs about 100 lb. more than the VQ35. I think SnyperZ's LS2 build is pretty impressive.

There is a kit for doing LS swaps into the 350Z, I just don't remember who provides it.
The LS3 is aluminum, but there is much more structural support around the cylinders than on the VQ35. It has serious power potential. If you want to go ***** to the wall, an LSX is an iron block with quite a few more head studs. It will take a LOT of boost, though it is heavier than the LS3.

Note, the 2J is a heavy motor (cast iron straight 6), which will offset your weight distribution quite a bit. If you are not that concerned about handling, it may be a non-issue.
The VQ35DE is about 330 lbs, whereas the 2JZ is nearly double that at about 594 lbs. An LS3 is somewhere around 415 lbs.

I think even the LSX is lighter than the 2JZ, and is capable of a LOT of torque/HP.

Im not super familiar with the 2jz but the last i researched the single turbo swap on the 2jz alone cost 10k and thats if you already have a 2jzgte installed in your platform. Quick search online shows a jdm spec 2jz with trans,harness and computer is another 3400 even though computer isnt needed still need the harness. Figure all the custom fab work to install it plus mods to fuel system for single turbo system to work another 3k unless you do it mostly yourself. These are just estimates but unless something has changed from 2 years ago(which it probably has but i can imagine by much) when i checked out swapping a 2jz into a 240 your looking at roughly 16-17k for 500hp although system should support more with a little extra invested.
In comparison ive estimated roughly the same for 700hp from the vq35de with sasha's 6765 turbo kit, custom fuel system built by me with parts from various sources, meth kit, cosworth intake, headers, jwt cams, haltech, coolant system upgrade, and ipp stage 2 block with hks head gaskets, ip girdle, and arp l19 head studs.
granted im just sourcing parts atm and ordering, it wont actually go togeather until next year when i get back from deployment we will see what i actually make then.

I can do the 2jz swap with everything for under 10g thru my sponsor (www.shiftedperformance.com)...and the short block id do myself....

a turbo'd LS swap makes a ton more sense. its a 6L v8. theres a cheap production kit to do it. LS motors are super easy to source and domestic aftermarket parts are way cheap.
JDM upgrades are much more $$ than USDM. A 88mm turbo on a LS2 swap will cost about 1/2 what it would to properly build a 2JZ. read supraforums. Big hp cars there are just as expensive as a VQ. Then read vette/G8/etc forums and see how cheap they can make 800+whp.
