LS1 240?? (Aries)

[Dustin601]

alright, well don't think i am some kid just dreaming. not a troll, or a noob, or none of that stuff. i have been searching, and there only seems to be one person that has done a v8 in a 90+ 240, and it is Aries on this board. he did an lt1, but i want to do an ls1. i know there is supposed to be a clearance problem with the rear sump oil pan, but the gto has a front sump. if the oil pan is the only clearance issue, i can work with that, but i was also wondering about brake booster clearance and exh manifold clearance. i know Aries can't really answer the oil pan question, but his experience will help me with the other 2.

Check FA, some guy is in the process of putting a v8 in a 240. He has a nice writeup with lots of pictures.

[Dustin601]

oh, yeah? well when i click on it it said invalid forum

[andrave]

aries is def. not the only person to swap a chevy v8 into a 240... its been done to to datsun/nissan RWD cars about a billion times, including the 240sx. aries was supposed to be selling kits to bolt them in though.

I have to butt in and be a smartass, but how about one of these instead?

ha, would love to, but will have to settle with it's less expensive little brother

[nismofly]

oh come on now...you know you just want to get a twin turbo lingenfelter ls6 in there...now that would be fun!

get er done

[dfw240_EE]

That 7.0 is the rumored engine for the upcoming C6 Z06. I don't believe it is official yet though.

[nismofly]

no it is, there was a thread about the new z06 on here somewhere

<<<<<<<< Instantly dumps a load in his pants at the mear thought of such a beast.

[dfw240_EE]

Yes, that's where I first found the pic. However reading other forum posts on the subject there is some suspicion wether it is real or not. They say the back window doesn't look right, so it might be a photoshop of a previous generation.

Until Chevrolet says something, we can't be positive.

[AmIdYfReAk]

anyone got pic's of that V8 in the 40?

[DriftinNC]

i wanna find out about an ls1/ls6 swap myself because that would be an awesome engine for one of these little cars. they are all aluminum so theyre light they are very powerful starting out at 285 hp and there are even stand alone pcms available directly from GM if you dont want to butcher a factory harness from a salvage yard donor

[burnin240sx]

the hell with a SB put a rela motor in there. like this fine specimen between my legs

[Aries]

Well, I can help you out with most of your problems.

The GTO motor will work because of the oil pump pickup location, and the design of the pan. They changed the pan from the center pickup/sump design of the trucks and camaros to allow the GTO to sit the engine lower in the chasis, effectively eliminating 20% more body roll durring cornering.

The brake booster clearance is not an issue. Getting enough vaccuume to it to have effective brakes is. I use an electric vaccuume pump after my last trip off the end of the track.

As for the exhaust manifolds, you have 2 choices. Custom headers (about $2000 from most performance shops) or porting/extrude honing the stock manifolds. The stock manifolds have a rear mating collector, which limits the manifold's interferance with the motor mounts.

Here's a few pictures of my new 396, and of the old motor in the car to give you an idea of the setup.

All Forged 396 LT1

The Shifter, gauges, and controls that have to be added for the swap to work. No your stock speedo woln't work.

The old motor. 350ci LT1 with 400hp of nitrous.

As for building the kits, I sold an LS1 kit to a man in FL with a 90 fastback 240. He's got the LS1 in and runs in the 11's on a stock motor and T56 trans. I've sold 2 LT1 kits, 1 of the cars broke the unibody junction at the firewall by using the LT1 solid moiunts with a big block chevy, the other still hasn't finished building his motor to put into a 97 with an S15 front.Currently, I'm not producing any more kits other than in house projects at the shop because I got tired of being blamed for faulty product when people weren't using the motor that the mounts were designed for.

I also have here in town a highschool friend with an LS1 in his Z32, in the shop, an LS1 in a Z31, and next in line for the shop a Z31 getting a 383 LT1.

Let me know if I can help you more. I'll be happy to give you all kinds of pictures with the exception of the motor mounts and custom crossmembers. (I hold the patent on them)

[pmkls2]

I would like to know how well these cars handle with a standard small block chevy in the front ? If the handling can be maintained using a LT1 then an ls1 swap should be pretty good as well

[Chingon]

i know of guys saying as much as 27 lbs in fd's and losing weight in fc's.

[Aries]

the S14 gains near 50 lbs with an LT1.Funny thing is, that's with iron heads. with aluminum heads, the car only gains 22 lbs.

The LS1 is even lighter. Only gaining 13.5 lbs in an S13.

[DaConfusion]

n00b q:Is the total price of your swaps cheaper than a RB26DETT swap?

[DOOM240sx]

I'll stick with a NISSAN motor...anything else is nonsense. American engineering doesnt compare. Besides that its just overkill IMO.

[pmkls2]

thats kinda what I thought aries and 13 lbs can be elimintaed in other ways. and my response to the american engineering comment is simply that there is not way you can take a turbocharged engine that is beefed up enough to keep up with a N/A v8 and still expect to have the same durability no matter who built it...........

now who's talking nonsense?

[DOOM240sx]

now who's talking nonsense?

Ok thats kinda coming across the wrong way...what i mean is any other crazy motor is nonesense...it costs you a fortune just for the install, custom everything can't be cheap.

[pmkls2]

well doom, i understand where you are coming from and depending on where you get the motor this could be a very expensive swap. my reasons for wanting (more like dreaming) to do this swap are the origionality and the fact that bolting a bone stock ls1 can get you down into the 11 second range. i dont know about you but that makes my imagination go wild thinking about what you could do with a few aftermarket bolt ons or a little nos.........

[Aries]

LS1 with a cam and a 200 shot goes 9.62 in a 3200lb trans am.drop 1k lbs and try again. looking more like 8.90's with the same setup, assuming you can get the suspension to plant the power

[pmkls2]

The thought of that alone not only makes me shoot a load in my pants but that is also the reason I want an ls1.........Im also a GM guy at heart but Ill never part with my 240..........

[lovenismo]

What would be the (complete) price range of stuffing in a ls1 compared to godzilla.

[pmkls2]

well the cost greatly depends on where you buy the motor and trans, on ebay it looks like you will pay $4k for an engine and trans combo out of a junkyard car, locally you may be able to get them cheaper. If you buy new from a dealer look to spend $6k just for the engine. a total price of $6 or $7 is probably a reasonable figure to expect using a used engine and trans but for that price you have a car thatll run in the 11's and you can go to the local parts store for replacement parts..........

[PureInsanity]

How well does the 240 rear ends hold up is my biggest quetion. Im actually considering this swap, that or a DE head on my E block. Not sure which way yet.
