I would be more inclined to modify the oil pan.

You'll need a low rise intake mani though.

Mine should be finished in a few weeks. I will post some pics.

Total spent on drivetrain will be about 4500cdn. It should be over 400hp pretty easy.

Oh yeah, forgot to mention - Mounts will be stock Chevy Mounts mounted in convenient locations. I will not be the one doing the engine swap, but supposedly it's not terribly difficult to fix these to the frame/crossmember. They're cheap too.

Anybody hear anything about the 302 swap latly? I got a motor and I got a 240, i just need mounts

This is my setup as it currently stands. If you're going to comment about carbs, my setup is equivalent to an LT-series in terms of mounting points and dimensions. Most of the info I post here are applicable to older gen-I 350 and EFI LT1/4. LSx blocks use different mounts. I used carbs for cost and availability of parts.

Borg-Warner T-5 gearbox (used in 3rd and 4th gen F-body)
ATL fuel cell

Fabrication of the subframe is necessary, but the motor sits fine. Driveline angle is correct and it has good clearance between the strut towers. The locations of the accessories have not been finalized yet though.

I have hood clearance issues due to the carbs, but if you're going with an LT block hood clearance should not be an issue.

Notching of the firewall was not necessary, but doing so allows a clutch R&R without lifting the motor.


I'm hoping the car will be finished by the end of the summer. Anybody local is welcome to meet up and check out my setup in person. I'm trying to convince the shop to release a bolt-in kit for gen-I/LT-series and LSx for much less than the cost of the Hinson kit (Hinson didn't even have a kit for my setup).

What are people using for mounts other than HSC's? I know that there are alternative solutions which would be much more cost effective.

Also, has anyone tried HSC's master cylinder? Also, their fuel system seems pretty decent. Anyone try that yet?

do these mounts work with the lt1

So far they are the only people I've seen who has put together a kit for the LSx into S-chassis. The rest are just custom mounts.

Does this answer your question? I am not sure which mounts you are referring to, but generally anything that will fit an LSx will not fit an LTx.

i ono if this was already asked but can the stock rear end take all this torque?

xatracing makes a nice mount kit. "mikespeed" and "chin" now run them. chin makes them.
problem is, that the oil pan needs a skid plate cause it sits so low, its below the kmember

mikespeed runs a blower on his and drifts it. i think the rear can take it.

The KA/Trans combo is good for under 500lbs. The LSx/trans combo is around 630lbs. You'll be looking at a good 150lb or so increase. See links earlier in thread.

yea i know efi is better :blah: but how many of you have carbed 350s or 302s or anyt other small block v8? im not shooting for high numbers. i want just want easy n/a power. i was thinking a carbed lt1 with basic bolt ons (cams, carb, header, ect) id be pretty happy with that setup.

I don't know where you got those numbers, but every other place I look puts the LSx/6-speed combo lighter than the KA/5-speed.

LS lighter than KA
6 heavier than 5

Combo LS/6 lighter than KA/5

Your sources are wrong.

My Sources, were are yours?

I think those numbers a little inflated but I do agree the LSx/T56 weighs more then a KA/Trans combo. Regardless of that fact, how much weight does a turbo and all it's supporting accessories weigh? I'd say that brings the two motor combos around the same weight. Now lets bring into the fact a turbo KA is probably not as reliable as a stock V8 pushing the same power. With that said, the LSx swap is a damn good route for anyone with the cash.

*EDIT

Found this:

Clutch is included in those wieghts. Its 40lbs. Check back in this thread a couple pages for confirmation

You can get rid of a lot of the weight a v8 adds to your front by getting lightweight body parts (carbon fibre hood, fiberglass fenders, you know that kind of stuff stuff) relocating your battery, getting rid of some superfluous accessories like AC and PS, and what not. Get creative with it... Im assuming that a v8 240sx would be more of a strip car or soemthing like that than anything because of the engine, so you wouldnt really need that stuff.

But really, alot of the weight added is at the tranny, which is located near the center and bottom of the car, so that shouldnt affect the weight distribution too much.

Id say if you do that kind of stuff, the weight up front actually affecting the weight distribution of your car wouldnt be too bad, which can easily be offset a little by having a full tank of gas lol.

Well, this is from Hinson, but I've seen it other places as well:

"The aluminum GM LS1 and LS6 engines are extremely light power plants. With the complete removal of the KA engine and transmission, the project car's final weight is less than the total gross vehicle weight of a stock Nissan 240SX. The LS1 T56 combo is 128 pounds lighter than the KA four cylinder it replaces."

http://www.hinsonsupercars.com/faqS14.htm

Its wrong wrong wrong.

I believe Hinson used an automatic transmission (among other things) to come up with the added weight of the KA.

Coming from someone who's collecting parts for the LS1 swap I can honestly say I know the KA is lighter than the LS1.

about how much would a shop charge you for this kind of swap.

Way too much. Just the custom fabrication, custom mounts, custome driveshaft, wiring, et cetera, et cetera... ITs alot of work.

I'd say at least 3 grand.

If you're handy with a welder (among other tools), or have friends that are, and do plenty of research it can be done within a budget.

As for having a shop do it. Pretty expensive.

ya i figured... although 3 grand doesnt sound that bad... i can get my hands on a vette ls1 for dirt cheap through some of the old hotrod guys at my work. but the fab is what would kill me. and i dont own a welder but i think i will soon, maybe some welding classes also, to PERFECT the TECHNIQUE hahah.... its handy to have. it would be nice to have a shop do it but im sure it would be somewhere like 20 hours of labor or so if not more.. and at 80 an hour or so for labor it would get pricey not to mention other parts you would need.

THANKS GUYS

XAT's swap package starts around 10g's I believe...

http://www.xatracing.com/ls1.htm

I was looking at doing it myself but the damn H.O.A. is on my back!

I just priced it up. From my (generous) estimates they're charging about $4000 for labor.

lol.... damn...

What's the price range when you say it's dirt cheap?

sorry to bring this back up...but i want to know has a 95-04 mustang motor been put into a 240 haven't found 1 yet......
i'd like to see if it was done...
i have heard it was wide and might be done...
i'm sure someone has the money to do it...
:blah::blah::blah:

I know of a couple ford 302s put into S13/S14s.

people on this forum have said the dohc ford 4.6 or whatever is too wide to make it in the engine bay without a signifigant amount of work..
