vk45de in a 240sx?

Well will it fit, or is it too big?

I would guess that its to big seeing how the vg30 looks like its a VERY tight fit into the 240.

But, why would you want to do this anyways?

v8:cool:

just because it's V8 doesn't mean it will own the world. i mean, it WOULD be kool, but i would rather have an RB26DETT any day of the week. also, it would take ALOT of work to get a 45 in there.

VK45DE is badass...340HP V8...nice

Anyways...if a 5.0 Liter Mustang GT engine can fit in a S13...why not a 4.5 Liter Nissan V8?

It'll take some bank though

oh for sure it'll fit, but with a good ammount of custom fab. i would think.

How much would you say a full swap (labor and parts including engine) would cost? All i want is a broad estimate.

well, as a comparison, the price to swap an RB26DETT into a 240SX is not too far below or above $10,000 usually, and that engine would probably go in relativley easy compared to a V8 that's almost twice the litre-age. i would say at LEAST $10k, but that also depends on how much a VK would cost. i would think they would be pricey...but i'm not too sure.

also, because of the weight of this engine, it would totally throw off the handling and balance of the 240SX you would be putting it into. this would pretty much be a straight line car and that's about it.

that would ruin the spirit of the 240sx, dropping in a v8 that probably weighs twice as much as the ka or sr, if your gonna go big displacement, go with the rb 26dett. that way you can have handling, and power, not just power like youw ould have with the 4.5

where are you goin to find a VK anyways? the nissan R390 are sooo rare to start with.

i thought the VK was the engine in the Infinit Q45??

:confused: confused :confused:

ooops my mistake, i confused the VH45DETT with the Vk45DE. okay now if its the VK its definitly not worth it. if its a VH45DETT. then its like the god of all nissan motors, a 4.5 liter twin turbo V8 that puts out something just shy of 500 from the factory.

Why not Tat? Here are the specs...

VK45DE (Q45 Motor)

4.5 Liter V8
340HP
333TQ

0-60 in 5.9 seconds...and quarter mile in 14.8 seconds

Hmm and that's in a 3800 lb car...

Now in a car that weighes 2600-2800 lbs...you'd be in the low 13's...high 12's if you could find a weigh to get all that power to the ground and get some custom tranny (either manual or sequential) to hook it all up

what car has this vh45dett?? any pictures of the engine or the car?

nissan R390 Le Mans racer. go to the R390 forums to see pics of it.

i personally think it would take more money then it's worth to shove a VK in a 240SX. but then, that's because i'm a huge anti-fan of drag racing, which is pretty much all the car would be good for with a VK in it. now if you were drag racing, then it would probably be worth it. but for drifting/SCCA/anything else that utilizes the car's handling, you'd be screwed with a big ol' V8 up there. i'd rather have an RB26DETT, which (according to alot of people) ACTUALLY makes around 320hp from the factory instead of the 280 that Nissan says it makes in order to slip under the self-imposed Japanese HP restriction.

I agree that dumping that V8 wont help the cars handling but I'd like just for messing around town...think...more double the torque you have!

LOL

The original Infinity Indy V-8 is based off of the VK, go for it. I've thought that I might like to put one in a hardbody pick-up (need an interesting daily driver once the rb26 get in) plus IIRC the weight difference isn't nearly as big as what people will tell you.;) Might be something worth further investigation. Hmmm (said scatching chin).

if a 5.0 Liter Mustang GT engine can fit in a S13

The 5.0 can fit into a small engine bay b/c its a pushrod engine. Checkout the difference in size between the 5.0 and the newer GT's 4.6 liter DOHC. (the v45 is a cammed engine by the way)

http://www.brentroad.com/photos/redneck350/fullsize/1372.jpg

The only reason I want to drop a v8 into a 240sx is because I want to beat the domestic racers at theyre own game (and no, i will not drop a domestic engine into a 240sx:o) The vk45de and vh45de (vk sold in newer q45's, vh sold in older) is basically a "domestic inspired" nissan engine. It has the reliability and performance of a nissan, while having the size and 8 cylinders usually found in domestics.

The bottom line is, how can we get one of these in a 240sx? How much would a custom swap shop like unstable hybrids or something charge for this? How much will parts cost? What aftermarket are available for these engines?

And remember, there is no replacement for displacement. 8 cylinder nissan engines rule:frog:

the tranny would be the problem, i was reading some where on this forum or freshalloy that all nissans rwd car used the same engine monts( i dont know if it is true but they installed rb25det with out any mod of the car. and it would not cost 10,000 to drop a rb motor in a 240. the 6-7 would closer to reality.) what tranny would u use for this swap( auto tranny suck) if i am wrong please provide info thsi would help me out thanks

i don't know where you've found your info, but it's near impossible for a 4.5 litre V8 engine, which is no doubt ALOT wider then the stock engine, to fit into the engine bay with no mod at all.

dont know if you guys have seen it or not but there is a guy in Texas named Aries who has an LT1 powered S14. I think it's an awesome swap but there is a video on houston-imports.com of him gettin killed from about a 45 mph roll by a turbo lude running around 10 psi. I'm sure that the LT1 powered s14 is a beast from a stop but from a roll it just got killed. here are some pics of the guys car.

More info and pics of Project 240SS (http://www.limecreekmotorsports.com/project240SS.htm)

i give the man mad props for undertaking such a no-doubt laborious and money-sapping project...but honestly, i cannot stand it when people throw big ol' domestic V8's into such a pristine creature as the S14. makes me shake my head. but hey, his car, his money, i can't tell him what to do.

ahhh yes aries car. brining his car brings us to another point. if he spent all that money to put money in a LT1 engine, which is a pretty strong motor by the way, 340hp and over 350ftlb of torque strong. if he still got creamed by a turbo H22a. then why spend all that money on a V8? when you can just like 5 grand on a t3/t4 hybrid turbo running 21lbs of boost with forged internals. that will well bring you into the 12's. which much less money

EXACTLY!!!!!

I'm considering doing a VH41DE in my recently purchased S13. I am fairly sure it will fit physically. I will probably be cutting the firewall and moving the engine back about 20-25cm to keep weight distribution nice and give me room for turbos in front of engine, plus intercooler and radiator. Being that the Q motor is DOHC and 90degree V rather than the VG 60 degree V im not sure how well it will clear the strut towers. I'm damn near sure it WILL fit just from looking, but not sure about how tight it will be.

And by the way, there is NO SUCH THING as a VH45DETT and there never was. The engine in the R390 is the VRH35L and its a 3.5 liter twin turbo making about 600hp with intake restrictors. The engine pictured is not the R390 engine either, count the number of exhausr runners on each side. That is the engine from the early 90's Nissan GTP car known as the NP35 and P35, it is known as the VRT35, and guess what..... ITS A V12!!!! That is an extremely rare engine!!!! There is a guy here in FL who has an original P35 chassis that was converted to an open top WSC car and runs a Ferrari V8. I think it's called the X-250. He races it in HSC (historic sport car) races like before the main events at the Sebring and Daytona endurance races. BTW jeelanim, I post here very infrequently so if you want to contact me it would be best via email at Freethinker41@yahoo.com

A q45 engine is WAY bigger then a 5.0 mustang engine..........


DOHC vs OHV.......

the heads are like 3 times the size of 5.0 heads.




r390 makes 550hp.......
where in Florida do you live?

I'm back and forth between Fort Lauderdale and Palm Beach a lot. Currently live in West Palm Beach, looking for place in Broward.

-Sean

want good power at a great price = CA18DET

good stock power and great potential at a decent price = SR20DET

want a lot of everything on a budget...RB25DET

You want a lot of everything and need huge hp get an RB26DETT

An RB26 can make more than enough power to make a RWD spin it's tires through all it's gears...the engine is great stock and astonishing modified. Some may think that a V6 or V8, either Nissan or not, is a better idea for the 240sx in terms of potential, but really for the price these 4 engines are nearly impossible to compare to...your best bet in having a chance to meet their cost per hp is a turbo KA. I'd be very surprised if you could get the VK45 to fit without spending over 15-20k for both engine and swap...then comes modifying it since you want to take advantage of all that power and not get killed by dinky 1-2k budget KA-Ts so now you are in the 20+k when you could just spend 10k on an RB26 and spend the rest on performance. I'm sure 10 grand in mods on an RB would make for one badass beast :iceslolan

:nono:

let old threads die

start a new one

cool im in west palm beach too, palm beach gardens to be exact, give me a ride in your s13 one day haha, 240s rule
:iceslolan

since this is the screw everything i want a V-8 thread...

why not just get that new Nissan Armada 5.6 310HP 385FT/LBS i bet
that thing could lay-down the law.

or even better the Ford 7.3 turbo Diesel you could kick some ass and you would have the only 240 able to pull a boat.

Hot rodding started with people that wanted something different and faster. So it takes some modifiying and work. I think it would be a killer setup. Why do you think Nissan uses this engine for the indy cars. Encourage don't discourage.

Hey, jerk... quit bringing back nearly year old threads! And welcome to AF!

yet another reviver.......happens to often now.

Well, since the thread was revived, I thought I'd post on this subject.

In the Silvia forum, there is an Australian member who swapped a VH41DE(2nd gen Q45) into his car. The VK's dimensions are probably similar to the VH's, so the swap can probably be done. It's an old post, so reading it will probably require a search.

As for the issue of engine weight, a VH45DE weighs only 521lbs, according to an article I saw in Road and Track. The VK is probably similar. The weight really isn't much when you think about it, comsidering SCC said a KA was 493lbs. So sure, the car gains about 30lbs, but don't you think that could be saved elsewhere?

Even if you don't go for a weight reduction, think of the power gains. With a stock VH41DE, the weakest of the Infiniti V8s(266hp stock), you'll have over 100 more horsepower than with a stock KA. With a VK, the gains go up to nearly 200hp. Keep in mind those motors are stock, so you wouldn't have any compromises on reliability.

Btw, if you want to go with a domestic V8, the LS1 only weighs 411lbs or so. Not only is it aluminum, but the OHV hardware also makes the engine lighter(vs OHC), with a lower center of gravity.

Very true...and I bet with a nice exhaust, intake and some mods...they would sound killer...imagine Turboing VH45...the blow off valve...the exhaust note...the intake sucking...the turbo spooling...that would be amazing...

I'm so surprised to see this thread hasn't been closed as it's been revived twice...I mean it's a decent thread with barely any purely argumentative replies so it definitely has some use for people considering v8 swaps and their benefits.

Maybe if the thread was locked, some of the more informative posts could be pasted into a V8 swap FAQ.

I also forgot to mention that OHV V8s like the LS1 are typically narrower at the top than the OHC V8s like the VH and VK. If any of the motors will be a sure fit, it'll be the OHVs.


]Very true...and I bet with a nice exhaust, intake and some mods...they would sound killer...imagine Turboing VH45...the blow off valve...the exhaust note...the intake sucking...the turbo spooling...that would be amazing...

If you think a VH would be good, imagine a VK. Impul Hoshino makes a 5L stroker kit. Looking at the gains from 280ps->340ps, the kit would probably produce 400hp(340hp stock) in a US-spec motor. There's also a supercharger from a US company good for 450hp on just 7psi, but at $10k(including air-water intercooler), that's a bit pricy.

I'd love to see if someone could get their hands on the flat-plane crank from an IRL-spec VK. A higher-revving 3.5L VK would be interesting to drive.

I Say Why Stop At The 4.5l.... Get The Vk56de!

Its Only 22 Lbs Heavier Than The 45 And Similar Dimensions....

I Say More Power To You! Slap The Neigh Sayers/purists In The Face And Do What You Want. If I Could Find A Decent Vk I Would Consider Swapping It Into Something People Say It Can't Be Or Will Adversly Effect The Handling Or Whatever Just To Prove Them Wrong.

The Torque Of That Motor Would Be Enough To Melt The Rear Tires On Command.

although this thread is old, id say that i have a similar project lol. i want to slap not just the factory version of the VK45DE, but the race version. i want to convert my 1993 Sentra to rear wheel drive and slap this race only engine to make serious power. of course handling will suffer as it is a heavy engine and is pretty big. but with modifications and alterations, anything can be done :)
