350z

i have a 95 240sx after i blow my sr motor im planning to swap in a 350z motor in it so far i made the mesurements and it will fit only thing i dont know if it would be a good i deal then try to turbo it up

VQ35DE is like $6000 :eek7: (for a decent one) and runs around 280hp stock i think (about the same torque). So turboisizing it would be a decent amount of power. But that's definatly a lot of money, and its a a 6-spd v6 so its gonna be good and heavy. I don't think it's a good deal at all in my opinion. Doesn't really make much sense unless you were doing just to be different.

still i can bust out 6000 grand i just bought a 4800 dallor s14 98 front clip so ye its not hard and it would be diffrent especaily if i turbo it up cuz it would be a killer cuz u know the skyline is 280 hp and the z is the skyline killer because skyline twin turbo 280 hp z only 280 stock non turbo

I thought you have s 14 silvia that what you said in the eclipse forum

A) VQ35 is all aluminum alloy, weighs little more than a KA, but not much.
B) VQ35 now is pointless except for bragging rights, a VQ rods can't hanlde more than 400Hp they break, so when you go with a turbo, you are limited to 400Hp, an SR, Rb and VG can get you that.
C) To go above 400Hp you will need to replace the rods, but it is not like you will go in and tear down the whole engine to replace the rods and then put everything back together, while in there might as well put high performance stuff like pistons, crank and the whole sheray and once the block is done you can go to 800Hp.
D) If thats the case why not buy a VG30, tune to 400Hp, when ready rebuild it and then still get the 800Hp but!!!!! since it is not a new motor, there ppl with years of experience, the parts will be cheaper, no shops experimenting on your ass, and you will not have to wait for something to be made, tested then put on the market. Am I making any sense?????
One last thing, japan car maker signed a some agreement to keep the power at 2something Hp, all you have to do is adjust some stuff on the car and you are gone to 400Hp with no new mods, Z can't do that.
Really this is my last point, $6000 for the motor, what about the tranny, I checked, it is $3500, and Don't forget the harness and ECU, well since not too many at the local yard yet, you gonna have to buy from dealer, add an extra $6000 grand, what is the grand total???
But, like I say, if thats what you are interested in, go for it, don't let others steal your dream, I'm just trying to show you what you are looking at, hell if I was in Clai, I would volunteer to help, but I am in GA.

don't forget the extra $2-5000 for the turbo job.

:iamwithst:

Yeah that too.


Thought the Greddy kit was $4500?????

BAH u killed my plan :..( and yes i have a s14 haha nds its my silvia with the motor and the right hand drive conversion

Sorry.
Better finding out now then when you have a VQ then hear you need an extra 14 Gs to make it work.

Listen you can still take the cup though, Buy a VG30 TT, around $3000 for engine, tranny and harness, swap it in, to get 400hp is easy. you are still $3000 under, blue print (costly) your engine with all the goodys (forged stuff) or rebuild it for around $1000, buy bigger turbos for around $1500 and $500 for aditional stuff, for the same 6-7 G's you will have around 700-800hp at the wheels, and bragging rights, not too many 800Hp street legal 240s' out there you know. OH almost forgot, add around $2000 for labour for the engine swap if you are going to pay someone else to do it. But still cheaper than 14Gs not including labour. :2cents:

ye true true well like i said i want to do that cuz no one has done it yet ill be the first nice idea huh

The VQ isn't a bad motor at all. A friend of mine was thinking about trying this swap if he gets a 240SX.

You don't need to get the 350Z's VQ35DE. There are older ones you can get, like the one from the '01+ Pathfinder. I've heard you can find those for as low as $500. They make 240hp, but it shouldn't take too much work to bring them up to the 350Z's power level. Either way, you can't beat the torque. :iceslolan

You can even use the Pathfinder tranny if you want, or to be a bit more exotic/sporty, you can look for a G35 Coupe or 350Z tranny.

My friend was thinking about running nitrous, because of the convenient "on, off" nature. If you did this, you could probably get away with at least a 125-shot. More shouldn't be a problem, with more fuel.

Boost is a bit tricky. The compression ratio is pretty high, so you'll need to drop that to run any serious amounts of boost. Replacing the rods would probably be necessary, too. The block itself is pretty sturdy, even built stronger than the 2JZGTE, according to a mechanic at AEBS.

If you can find a motor for as cheap as I mentioned, I say go for it. There's also the option of a JP-market VQ30DET, which was built for boost, with a lower compression, etc. It was used in the Cedric/Gloria twins, basically a JP-market Infiniti M45. The motor is rated at the traditional '280ps,' but the smaller VQ25DET has the same rating, too. :rolleyes: I've seen them for around $1100.

Ummmmm HELL NO!!!! the 2JZ engine was built to handle power up to 750hp no VQ engine can do that in stock trim, so there is no way it could have been stronger.
Secondly you have to understand the diff between a truck and sport car engine. You guys think they are the same cuz of the code....true, but they arent the same in performance, the manufucturers change the runners, longer for trucks and shorter for sport cars. Longer runners boost Torque but become inefficient at high RPM, shorter runners are better at top end but give you a weak take off. You see the motor in my sig, Yamaha built that block, it has two runners per cyl, the longer ones are opened 24/7, and the short ones open at 4000RPM.

Ummmmm HELL NO!!!! the 2JZ engine was built to handle power up to 750hp no VQ engine can do that in stock trim, so there is no way it could have been stronger.

How do you know? No one has gone that high with the VQ yet. Top Secet has gotten almost 700hp with a VQ, and I'm sure the number will get higher soon. People used to think that the limit was about 550hp, but it's much higher than that. Did I say you could just boost a 'stock' VQ past 2JZ power levels? No, I said the block itself was stronger.

I'm just repeating what a mechanic at AEBS said, anyway. Here's a condensed version of the post found at My350Z.com. I've also posted the massage in its entirety in the Skyline General Discussion forum under the 'From Concept to Production' thread.

Paulus said the VQ block is are stronger then the supra turbo blocks although they are full floating cylinders...
How much overlap is there between the bearing journals, how thick is the material between the journals, how much counterweights are used for properly dampening the destructive harmonic frequencies, what is the diameter of the bearing journals ( the larger the more oil cushion it creates, thus preventing metal to metal contact ). For instance, the Honda NSX has only 0.140 inches of material between the first two connecting rod bearing journals, and at high horsepower above 1000 it breaks at this junction. Two of current high profile drag racers in the import scene have been battling this problem. The v-6 Toyotas and GM's have this problem too. The Nissan VQ35 does not have this problem at this junction because it is 0.710 inches thick between the first two connection rod journals...
The Nissan VQ35 block is constructed from a high pressure die casting procedure and it consists from high density Aluminum using 4 bolt mains with a longitudinal girdle to support the main caps. The Toyota 2JZ crankshaft is an inline 6 style and whenever number 1 cylinder fires, the crankshaft undergoes serious flexing when this power is transferred to the flywheel. That's why you will never see an inline 8 Topfuel or Funny Car racing engine, just horrible flexing with detrimental harmonic vibrations.
Furthermore, just with Top fuel racing engines, the blocks are made from Aluminum to absorp harmonic vibrations thus reducing cracking, the Toyota 2jz is made from cast iron.

Secondly you have to understand the diff between a truck and sport car engine. You guys think they are the same cuz of the code....true, but they arent the same in performance, the manufucturers change the runners, longer for trucks and shorter for sport cars.

I'm quite aware of the difference. Thus I pointed out that some additional parts like the 350Z's short runner only(not variable) intake manifold, for example, would be needed to bring power closer to the 350Z's level. A Maxima owner tried to fit this manifold to his VQ35 in place of his variable unit, but unfortunately, the hood wouldn't close over it. :lol:

You might like to know that the Pathfinder motor is a completely different generation VQ than the 350Z's as well. That's another reason why it would be cheap to buy. The VQ35 used in the Pathfinder and '02-03 Maxima is the second generation VQ. The first was the VQ30DE from the '95-99 Max and VQ30DEK from the '00-01 Max. The third generation VQ is the current version used in just about everything.

You see the motor in my sig, Yamaha built that block, it has two runners per cyl, the longer ones are opened 24/7, and the short ones open at 4000RPM.

Yeah. The VQs have variable intake manifolds in certain applications too.

put a northstar in ur 240sx

that would be pimp :-D

we can do that??:eek7: wow where have i been hiding

Do what? The Northstar? That'll take quite a bit of fabrication and parts matching. Still have to find a rwd tranny that will fit, too.

Why not the Infiniti V8? At least it will have a rwd tranny in most cases, even if it will probably be an auto. A VH41DE swap was actually done by an Aussie in the Silvia forum, too.

If you mean the VQ, few if any have done it. Just doesn't seem practical to some. Many don't understand why you'd swap that in instead of a VG, which could have stock forced induction.

The advantage of the VQ though, is that it's pretty light, about the same, possibly less, than a KA. So with a VQ, you're basically getting more tunability, better weight distibution(V6 shorter than I4), and much more stock power and torque, which is especially good if you don't want to mod it too much.

still i can bust out 6000 grand i just bought a 4800 dallor s14 98 front clip so ye its not hard and it would be diffrent especaily if i turbo it up cuz it would be a killer cuz u know the skyline is 280 hp and the z is the skyline killer because skyline twin turbo 280 hp z only 280 stock non turbo

$4800 is a little steep for a 98 front clip, and if you can drop another $6k right away on a second clip more power to you....but weird talk aside the Z is in no way a Skyline killer, one the 280HP is a limit imposed on the car due to HP laws...extracting way more power out of the RB26DETT is a simple affair, then you have awd on top of that....the Z would have it's ass handed to it in the 1/4, the standing mile, cornering, and just about any other performance category.

The Z is not a bad car, it's designed to be civilized though.

ye ye true

Z is no match for the skyline.
Even mercedes cars have dual runners, but most use a system of butterly internal passages, but the SHO has as you can see them on the outside, meaning at high throttle, you use both the long and short for a good amount of air ingestion, that is what I liked about them. In other applications you will use one or the other.

zeroneonzn , can you post some pics of your car please? i wanna see what it loks like



......

Z is no match for the skyline.

That goes without saying, but we're comparing their motors.

The VQ35 swap might be a bit harder than an RB swap, since there probably aren't many who have done it. There'll be less advice from experienced people(if any), and there might not be any installation kits.

It'll be hard, but it could be worth it, depending on what you're looking for. At the bare minimum, you'll have almost as much power as an S15 SR, and much more torque.

i have some on my site
but none with the new sr 20 in it
wait i have pic of the motor ill put it up too
http://www.zero_neonznzn.tripod.com

before i belive the SR swap ill need to see a pic of you holding a sign that says "AF Ownz me and my bad Spelling" while pointing to the SR in your car.

If i were gonna put a VQ in a 240 id use the VQ30DET ive seen them selling for 1500+shipping thats what top secret uses in their 350Z not the VQ35

hmmmm interesting

If i were gonna put a VQ in a 240 id use the VQ30DET ive seen them selling for 1500+shipping thats what top secret uses in their 350Z not the VQ35

Just curious, where did you see the DETs for that price? That's pretty decent. I've only seen one for sale a long time ago, and it was $1100.

FYI, the VQ25DET was already rated at the maximum of 276hp, which means the 3L is making much more. :sly: The VQ30DET could possibly be making even more power than the RB26 really makes in stock form(as much as 340hp). It'd be reasonable to assume the 3L makes that much power, because the JP market Cedrics and Glorias that use the VQ30DET give up little in performance to their 340hp VK45DE-powered USDM cousin, the Infiniti M45. :iceslolan

There's other VQs out there, too. They're available in 2L, 2.5L, 3L, 3.5L, and 4L will be coming soon(new '05 Frontier, Pathy, and XTerra). If you felt like doing more work, you could build a 3.3 stroker, a destroked 3.2, or a 3.8 stroker. IMPUL Hoshino has the 3.8 stroker kit, and AEBS has one too, but I don't know what the resulting displacement is.

What I find interesting is that EVERY picture is the same dimensions and quality... except for the sr20 picture. Brilliant doofus, you've managed to make yourself look dumber.

I found it there, it was a while ago and had an automatic. but i figured that it would just be a 350Z tranny, some custom mounts, and a Haltec away from fitting into a 240/Siliva

best motoring didn't like the VQ35 saying it wasn't smooth enough and only revved to 6600rpm whereas the other japanese sports cars went over 7000rpm. It'd be cheaper just to get another SR20DET. The engine also weights alot.

Yeah, good thinking. Hopefully everything would mount up, and you could use the stock driveshaft, etc. Wishful thinking, but it'd be nice if the 350Z cf driveshaft fit. If the 350Z tranny is too expensive you could probably settle for a manual unit from an '01+ Pathfinder. That'll at least get you rolling, and you can look for a 350Z tranny later.

Just about everyone says that. They all love the torque, though.

It'd be cheaper just to get another SR20DET.

Not necessarily. The SR bandwagon is in full force, and prices are rising. It sounds like zeroneonzn wants to try something different, anyway. If he got a VQ35, he'd have at least the same horsepower as an S15(240-ish), more torque, no emissions worries(USDM motor), the option of still going FI, and possibly even less cost, considering what S15 SRs go for.

The engine also weights alot.

The VQ has an aluminum block. It's only about the same or less than the standard iron block KA we had on our side of the pond. The KA weighs about 493lbs according to SCC. The aluminum VH V8 is 521lbs according to R&T, and the VQ should be even less.

ye so its ither that cuz im making my 240sx a track car im not sure what to do once the sr in it blows if to do that plan or get another sr :-/

y do you expect your sr to blow? are you planning to do something stupid with it ...................?


yes. i think you are.
