Yeah, there is a reason for it: it's hard, costly, and a fairly new swap. Your post is so vague I highly doubt you will be building a 10 second car anytime soon. And no, a "turbo swap" (whatever you mean by that) would probably be considerably cheaper than say, swapping in an LS1, although you never specified that engine either. Maybe a 5.0 swap would be comparable in price to the aforementioned "turbo swap", but that would entail a lot more fabricating because no one makes a kit.

 

a v8 swap is a great idea .
numbers dont lie....... with the aid of aluminum blocks and heads v8's have come along way since my dads old 383 stroker.
Ls1 motor
345 hp
350 tq
est. curb weight of 429........stock... wow.
as you know the rx7 guys have been doing this for years now as long as a few 240 guys ..
if it fits your application and your wallet .
ive done rb swap, sr swap and they all kicked ass..
but ride in an ls1 rx7 only once.. and the torque bugg will bite you on your ass. i say why not . nissan's vk59de (thinks thats the code?) would be a super sick swap. isnt there a d1 350z v8???
anyways why not- there still gas on the planet - might as well use it up:thumbsup

 

Ok thanks stinky for not trying to get some kind of stupid internet fight going. That's what I was thinking. The guy that's going to be doing the swap said alot goes into it but getting an 11 second car that get's 28 mpg how could you go wrong. As for the other guy if im going to do the swap in my car and some tires that's 11's right there. Build the motor, heads, cams, bolt on's maybe a small shot of gas and im already there. 10's here we come!!!!

 

HHAHAHA your chassis is gonna twist sooo bad. get a domestic, build a drag car

 

I doubt the chassis will twist much at all. I know of a number of LS1/2/6 Miatas that all make over 400rwhp and have yet to have any issues with chassis strength....and the Miata is flimsy (I own one, I know). The S chassis is considerably stronger.

As far as a v8 swap. Its cheap, reliable (in most cases) power. Only thing that could suck would be gas mileage. If you do one, go with the LS1 kit that Hinson Supercars makes.

Also, the 1st reply wasn't someone trying to start a fight, he was pointing out that your choice of words made you look like you didn't know what you were talking about.

Yeah, I wasn't trying to e-thug you. BTW, I think the LS1 is a great engine option.

 

Ok, Im not trying to get a fight started either. Im just trying to get some info before I actually start the build. The guy said something about a kit we would have buy but I don't know what company. Hinson may be it? Are there any members on the boards that had some good success with their v8's?

 

reason why people havent done v8 swaps in nissan's much is until now is because it just wasent that popular with the us import crowd.
there was a skyline australiia site i was a member a year go . and there are skyline v8 swaps regularly
it can be done but it will take time ,skill and money
if this is your first swap you had better do your homework
or , go to hinson super cars, they make a kit for a s13/ s13,rx7's ect.
or go to grannys speed shop , the do rx7;s
becides that , just start buyin parts ,reading up,and get dirty ..

 

lol, e-thug, I haven't heard that one before. Hey no hard feelings here man. Rock out witcha c*ck out!

 

E-thug...I like it! Correct me if im misguided but I like my 240 due to its drifting abilities. Yes I want it to be quick but not in a straight line. My point being, you dont see many V8 swaps because 240s are for going sideways (dont want all that weight up there), not straight!

 

considering a ls1 weighs approx. 429 according to jonas that's not a whole lot of "front weight" i remember someone weighing their ls1 the weight was not effected very much.

 

Yeah, it will not adversely affect the handling. According to Hinson "The LS1 T56 combo is 128 pounds lighter than the KA four cylinder it replaces." Keep in mind that they started out with an automatic 240. It should handle just as well with the aluminum block V8, as it did with the iron block 4 cylinder. I know it seems strange, but you just have to forget all your preconceived notions about American V8s, because this is a whole new era. If you want to complain about weight balances, go to the KA-T section and rain on them, because those guys are more nose heavy than the LS1 guys.

 

a s14 with a stock ls1 using hinsons swap kit and fuel nad cooling systems will run 12.2-11.8s
www.hinsonsupercars.com for a lot of indepth details the swapping of v8s into the 240s is still kinda new so not a lot of people have tried it. and its VERY VERY expensive to do right. i prived my swap if i did ALL the labor of instaling at around 13k plus cost of a 240 also not factorign suspension upgrades nessecary for that power to reach the ground. and thats with a 10% discount for being a member of a local board hinson supports.
the motor requires many many upgrades that other swaps dotn require.
the stock fuel and cooling systems will not work at all. and you have to buy or make motor and trans mounts. the stock 240 rear end will hold the power of a moslty stock ls1 as long as you dont drop real sticky tires on.
the ls1/t56 trans combo weighs around 128lbs less than a stock ka and transmission.
if you have a lot of money its a awesome swap. the car will be much lighter and extremely fast. but having all that power wont do squat for you if you dont have the right suspension to get that power to the ground. full bolt-ons and a mild cam and tune will net you low 11s, the appropriate heads/cam combo could possibly net you 10s with a strong nuff rear end and traction.
didnt realize a lot of this was already stated.

 

whole new era? have they worked out quad cam yet? ...
like nissan and toyota did over 12 years ago?

 

The "new era" is V8s that don't weigh a million pounds, and get shitty gas mileage.

And about your cut at pushrods: If it's not broke, don't fix it. Don't act like quad cam's are some brilliant new technology, they have been around for almost a century.

 

Ya learn something new everyday. Thanks for the info!

 

There is a guy in Orlando that has done a V8 swap into a trunk 240. The real kicker is that hes also done a carb/turbo swap!!! It looks alright but I bet it must be really fun to drive!!!

 

Haha, ok, replace "era" with another word. Maybe that was a little grandiose. I'm just saying that the 350 doesn't suck as bad as it used to.

 

My old man always tries talking me into puting in a "327 w/a 4bolt main" into my 240, and it is getting really old. The LS1 doesn't sound too bad though.

 

I think another reason that you don't see more LS1 swaps is because some 240 owners (at least myself) do not really care for american engines. I am all about HP/Liter!

 

HP/Liter? Direct your attention here: http://www.turbov6camaro.com/home.htm
Even the asthmatic little brother to the LS1 can be made into something decent with a moderate amount of tuning (is anyone going to complain about 120 HP/Liter?). Not everyone maxes out their engines to be the super number one best in the country, so we're not going to take max hp/max tq into account. It's really all about what the owner does (and wants to do) with the engine.

:1bowdown Aftermarket.

Comparing the swaps, keep in mind you're comparing the modification response of stock turbo engines vs. the NA LS1 (and other NA v8 engines). Turbo the v8 blocks and I guarantee you'll be happy with the HP/Liter ratio. :dancingna

EDIT: I appreciate both domestics and imports, it's all about technology. Nothing but love. :thumbsup

 

I just read in one of the turbo mags...they say its fairly simple to put the the (vq35de?) the motor from the 350z in a 240. Sounds hot...its all in theory and I believe they just started the project in the mag. I dont remember which mag it was ... but I only got it a couple days ago...so it should be a recent edition.

 

The magazine your talking about is the September 2006 Sport Compact Car magazine. They say its pretty easy but once your start reading into the write up on how to do it, it sounds pretty hard, it takes a fair amount of fabrication. The electrical seems confusing as hell, seeing as how the VQ35 uses a closed area network bus and a drive-by-wire throttle nothing will work without a stand alone and even with that your gauges still wont work, and not to forget the returnless fuel system. Seems to complicated, lot of splicing wires and wiring in new sensors and fabrication. Would be an awesome swap but not something I would want to tackle.

engineswaptech.com has the info on the VQ swap.

 

just do a sr20det swap and save some money

 

i jsut dont see the point in saying " i have XX per liter". who the hell cares if it doesn't make you faster? power per pound is ALL that matters.

angel and evrae205... do us a favor and explain exactly why LS1's are so superior. I'm not trying to say they aren't, I'm not biased against any of them, but statements without backing are just opinions.

And whatever you do, don't have any of those!

 

i stay away from the girl with the saccharine smile

is this a v8 looking so fresh and so clean in a 240sX?

 

Check this out. I will shut up now.

I don't remember saying anything about a certain engine being "technically superior" to the LS1. I was simply stating that it wasn't for me. My dad builds muscle cars so I have been around big american V8's all my life. You can burn me and own me all you want because I am sure that you all know more about it than me (no sarcasm intended). And I know that alot of other guys must share my "opinion", otherwise you would see more LS1's and less SR20's. But what the fuck do I know right? I am just trying to save myself the embarrassment of being proven wrong.

 

if you dont like american v8s theres nothing wrong with that. Its your preference. hoenstly I wouldnt own another american V8 besides the LSx motors. none of the other american motors have really impressed me so i can see where your coming from.

My trans am handles like ass which is why im still attached to my 240 even though it looks like shit now. but I look at power as nothing more than a price tag. I paid 9300 for my car and it runs mid 13s stock. I couldnt build a nissan that fast for so chepa so thats whyi bought the TA but i wont a handlign car too so i got the 240 still. I hope to oneday do a ls1 swap on a s14 so i cna have the best off all of my taste. looks,handling and cheap power. Hinson offers our carclub members discounts so it wont cost as much for me to build such a car as the average person.

 

I am sorry if I caused this thread to stray off topic.

 

nah its several peoples faults mine included. but hey thats nothign new to a forum.
