A Z weighs 3250 without the driver. BTW all those N/A mods would cost you in excess of $2000


That's not entirely accurate...

296.1whp/272wtq...N/A

I will agree though, that it's very expensive getting to those #'s on a 350Z, but then again, so is everything else associated with a car that cost twice as much as a tC does. The turbo kits are fairly priced the same though, and you will net....(what the heck am I telling you for...LOL. You already know what they put down on 8/9 PSI). But for Ben's sake, they do dyno around 230-240whp stock. On 8lbs of boost you can expect 400-440whp. But a tC on 230-240whp would win hands down against a stock Z as it's lighter than the Z. So, again, HP is only a fraction of the equation. And for every what is it...100lbs of weight you shed off, you only accuire like a tenth of a sec off your 1/4 mile time (could be off on the #'s, but I know it's some ridiculous equation like that).
Those mods JUST THE HIGHLIGHTEd ones are $4000. Thats a gain of 60 WHP for the cost of $4000 not including install if you can't do it your self. For $1000 more that Z could have had the Turbonetics kit and picked up 150 WHP. Like I said N/A most Zs don't make crap for power.


I wasn't saying that they did, just saying that they make more than what you estimated. It wouldn't just be $1k more just for boost. You would NEED to build the motor with at least some piston and rods so as not to blow up the VQ (as we know it's not that tough when it comes to F/I).
Considering I daily drive my turbo 350Z and have for 30k miles with the turbo kit and 50k total miles I think I can speak to requirements. My motor is factory stock. In fact the seals have never even been broken on the cylinder heads. I have the following:

Turbonetics Single Turbo Kit
Apexi WS2 exhaust
Motordyne plenum spacer
as my power mods. I recently added a ACT clutch and JWT flywheel too. In addition I have HKS RS coilovers, Nismo LSD, Hotchkis Sways, SPC camber arms and toe bolts, Cusco A arms, and about 50 other parts on the car. I drive my car EVERY DAY. To and from work. My last dyno was 380 RWHO and 371 ft/lb of Tq at 8 PSI on 91 pump. I have not had ONE issue. So no you don't need to build the motor.


Notice you have only 380whp/371tq, that's not enough to break the VQ anyway. Over on 350Zmotoring where the averaged boosted Z is in the 410+ and 400 ft/lbs. When you reach that much tQ on the VQ, that's when it starts to get scary. You have a Single T kit. Most of the ones on the forum I'm on are TT's @ 400+ whp. Some are running on Stock still, but there have been to many mishaps that would cause me NOT to want to TT my Z before getting rods and pistons. Don't think I'm saying the VQ is weak (I have a Z too remember). Just saying that if you are looking for 400+whp and are going TT instead of ST, then I would suggest getting Rods and Pistons first.
I won't speak to the TT kits as I've never owned one but the numbers I put up are my daily driving numbers. At the track I run 109 unleaded and 10 PSI of boost. That gets me 410/405. I've run that for more then one track session. I also know of several other ST cars making in excess of 400 WHP and Tq with no issues. I will agree the pistons and rods would be the safest way but there are tons of people over 400 on www.my350z.com on both ST and TT kits doing just fine.

I don't like the new body of the GTR over the older Square (Manly, I'll eat your young) body. The Z was an "out of reach" car in my eyes as well, but look I have one now. It just needs more power. Intend on drifting it. So, when the GTR does hit, I will keep an ear to see who is contemplating a motor swap and see what troubles they have in doing so. I won't have to do ANYTHING motor wise besides turn up the boost. Don't need anymore than 600ponies screaming from it (yes I know, don't need that much for drifting, but it's for bragging rights too).
I can tell you right now that won't be cost effective at all.

I'd guess the crate motor itself will easily cost in excess of $9000. Add in the fabrication of a swap and supporting mods (different mounts, getting the tranny to bolt up, wide enough wheels to put down the power, clutch, fuel pump, etc.) and you'd be way better off rebuilding your Z motor. Sourcing a used engine won't be easy or cheap either. Due in large part to the price and rarity of the GT-R, there won't be many scrapped cars even for years to come (you can't really run down to your local junkyard and grab a Viper engine easily, and that's with almost 15 model years worth of Vipers and SRT-10 Rams on the road today). You'd have no trouble building a beast of a VQ35 for less money.

Would it be awesome to have a GT-R motor? Yeah. Would it be worth the money? Probably not.

I sorta disagree with you. TTin'g the VQ in the Z already, is going to cost you larger wheels and a clutch.

There would be no need to build the GT-R motor when it is already pushing enough power to do what I want. No need for a clutch if I get the tranny.

I agree on the rarity of the engine, motor mounts (if I need those, could be a direct drop in like most Honda motors are for Civics, it still going to be a VQ you know).

I doubt the engine will sit in the same place in the bay and have the same mounts and such. It's possible but I wouldn't bet on it. Regardless, most engine swaps require a bit of fabrication and part sourcing (and don't forget wiring harness hell), even Civics. God knows swapping an NA 300ZX to TT isn't any fun. Especially assuming someone can't do the swap themself, labor is a beast on an engine swap.

I'd be willing to go on a limb and say that anyone who can afford to buy a new 350Z (especially a higher end model like a Grand Touring or something), and actually has enough disposable cash to do a $20k swap would really only be a hand's length away from being able to actually afford a GT-R.

I don't like the new GT-R's body lines. I prefer the older model. But for what I want to do (drifting), I would have to convert the AWD system to RWD, and I don't want to do that either. Maybe I might change my mind when it comes out, but at this point, I want the GT-R's engine in my 350Z = Sick as Sick!
