V8 240sx

[mazdized]

Does any one have any info on LS1 or LS6 conversion to a 240sx?

[pSY trek]

I dont think there are any LS1/6 swap kits for the S13/14. Everything would have to be custom made. Supposedly the LS1/6 engines oi pan wont clear the cross member, meaning you would have to run a dry sump system$$. If you want a LS1/6 in another light car, there are swap kits for the mazda rx-7. http://www.hinsonsupercars.com My brother is doing the fc/ls1 swap. It will be fucking nuts.

There used to be a website of a shop (limecreekmotorsports.com) that had done several of them, but it looks like the site doesnt exist anymore.

They were doing LT1/LS1 swaps, and I believe they were based out of Texas.

IIRC, the Fox Body Mustang 5.0 has a front sump oil pan, and fits an S13...there's one runnng around Gainesville...some 'neck with a beat up red S13 with a stock-ish 5.0, runs in the 13s.

And before the handling vs weight issue comes up...it's been proven that a 5.0 with accessories on only ~50lbs heavier than a KA with all the accessories.

The Datsun Z guys do this all the time...look around for info from them.

[proj240sx]

what do you mean by accessories on only? versus all the accessories. i've worked on my camaro 350 which i know is bigger than the mustang 302, but its still hard to believe such a small difference in weight between the 2.4 and 5.0, maybe alluminum block on the 5.0?

[orion::S14]

Hehehe...I meant "acessories on it only weighs...". My bad.

The KA with alternator, PS pump, A/C compressor, etc..is in the ~450lbs range IIRC.

5.0 in similar trim is a little over 500lbs IIRC.

Search on Google a little, I'd bet you can find specifics.

[thx247]

great idea, big project to undertake though.

[wootwoot]

putting a v8 in an rx is a sin.

[sepulchral]

a v8 in a 240 is really unique, u would be really cool!

NOT

[ThatGuy]

He didn't ask if you liked the idea, he asked if you had any info on how to do it. This is Tech, save the flames for dumbasses in OT or Chat.

[FastBack 240]

search. Not to long ago there was a member who had an LS1 in his fastback.

This is counter-intuitive

KA24=2.4L cast iron block/aluminum head/4 clyinder ~450 pounds assembled

Ford 302=cast iron block/cast iron heads/8 cylinder.

VG30dett=cast iron block/aluminum heads/twin turbo/6-cylinder and it supposedly weighs ~900 pounds fully assembled

[mjjstang]

NO, I think they made those 302's out of lightweight magnesium though.

[wootwoot]

you can get aluminum cylinder heads for the 302's, they save around 60 pounds i think. its really not the best idea. how much does a 302 have stock? 225hp? its really quite a pitiful engine, heavy and slow. sure there is aftermarket out the ass and you can pick them up for cheap but it sure wont be cheap to put it in your 240. if you want a monster engine in the 240, use an rb. if your mind is set on putting a v8 in it, i'd use one of the newer 4.6's out of the mustangs. they are atleast aluminum and ohc

[Prok0]

Heres a pic of the LT1 S14.

How much does an LS1 weight? I would imagine it would be somewhat close to KA since its aluminum block and heads...

If someone were to PROVE this to be true, i would consider doing this swap after my sr blows. If anyone has done this with the weight of the car measuered (not just engines) before and after the swap please post up some facts.

you might wanna do a lil more research before spewing retarded shit. Look into what kind of numbers a set of Alum heads/intake and real camshaft will pick up a small block ford. Also, 4.6 sohc motors are not alum blocks. only the cobra/mach1 is.

actually they are aluminum. only the 3.8 v-6 has an iron block.

Ported & Polished aluminum heads, a good cam, chip and injectors will give you a solid 100 horsepower

[wootwoot]

my your an ass. stock, they are slow and heavy, thats how it is. look at the hp per liter, not impressive to me at all. sure you can make them fast, thats why i said aftermarket out the ass. simmer your ass down and get off your high horse. also, the cobra blocks are iron again. they switched back for the supercharged version. i guess you showed me. im gonna go spew some more shit out of my ass now because i have diarrhea

[stillmatic]

Aries on Nico has done the LT1 swap. Just do a search for him. http://www.nissaninfiniticlub.net/forums/member.php?action=getinfo&userid=702

NO small block ford comes factory w/ alu. block, and ONLY the 96-02 cobras and new Mach I's have alum. blocks. GT uses a cast iron block. 03+ cobras also use the cast iron block as someone else pointed out. I probably see more mustangs on the dyno on any given day than you pass in a week.

[kidinthehall]

btw you owned yourself on that one...........i just went back and looked at the link u posted. it says plain as day "Block Material : cast iron"



As for making power with a pushrod ford, cyl heads/cam/intake manifold will make ~330rwhp with a decent tune, naturally aspirated. Modulars (4.6/5.4 liters) require quite a bit more to make any real power with one naturally aspirated.

[thx247]

4.6 sohc would never fit in the 240 engine bay. Its huge.

[240sxconversion]

yeah u have to understand the 4.6 dohc ford is 1-2 inchs wider then a 429. If u can fit a 4.6 in there, hell, go for a big block ford 429, 428hp. If i was u. and u want a v8, use a chevy 350 of some kind. because the fords have a straight exhaust mating surface which isnt really good because the headers are gona be a bitch. just my .02 cents

[kidinthehall]

agreed on the 32V motor. Its cool, but itd be pointless to try and stuff it into a 240SX. The LS1 or SBF would be a better choice for sure

i sure did :Ownedd:

[HATchTRICK]

Ther was guy at ATCO raceway with a LS1 swapped into his s13 hatchback. He had a pre-95 j30 rear and was runnoing 13.0's all night.
The same night i reana 12.8 with my s14 sr swap before i did the j30 rear...

[orion::S14]

302 weights I found via Google:

"Ford 289/302 V8 - 460lbs - (late 5.0s are a bit lighter)"

http://www.thecarsource.com/fords/engines/302engine.html
"Long block weight in pounds - 475"

302 with bolt ons = 13s in a convertible Mustang...take away 300lbs, it'll be awesome and cheap.

- Brian

[kidinthehall]

13.0s w/ an Ls1 in an S13 is weak.......car should be way quicker than that. unless his 60ft was just weak and it had lots of mph.

[thx247]

And stock evo's can run 12's or 15's...drag times can be pretty subjective.

Maybe he was practicing for brackets?

[kidinthehall]

Yeah, i can imagine some guy going though the effort of an LS1/S13 swap to be a bracket fag......

Like i said, im guessing the car prolly had good mph and a crappy 60ft......bad driver/street tires, etc.

[chingon]

the guy Aries on nico who did the lt1 said he had conversion engine mounts for the ls1 and a bunch of other engines.

Also, ls1 should be substantially lighter than the ka. I say this because the guy from wrongmotor.com (ls1 into fc) lost something like 75 pounds after the swap (ask around in teamfc3s.org/forum). And I do believe the rotary 13b is lighter than the ka.

FYI, you will need an lt1 tranny, since I think ls1's came w/transaxles.

[Zemus]

I know the 13b is lighter than an LS1, but I dout its that much lighter than a ka..

[kidinthehall]

LS1s Z28s/etc have transmissions, only the corvette uses the transaxle
