Ok guys and gals. Post up any questions you have regarding a v8 motor swap into a 240sx,

Weights:
KA with Auto, Cat and accessories = 596 lbs.
LS1 w/ T56, headers, and accessories = 468 lbs

That's right folks. The iron block four cylinder is 128 pounds heavier than the aluminum LS1!

LT1: 300hp Iron block, aluminum head.

Ls1: 350hp/350tq All aluminum

Ls6: Corvette Zo6 engines. 2001 year ls6 385hp/tq

Ls6: Corvette Z06 engines. 2002 and up = 405hp/tq

Ls2: C6 corvette/Gto engine. 400hp/400tq Big difference in low end.

Ls7: C6 zo6 corvette engine. 500hp/tq dry sump oil system.

Trannys.

all L series motors can use the following.

T5 5 speed. (lighest of the bunch.) Only good to about 400hp.
T56 6 speed. Viper tranny. enough said. ls1, and lt1 t56 are different.
4l60e automatic. ehh.


ECU. All Lsx ecu modules are basically a stand alone, once you get the tuning software. ls1 edit, hp tuners, etc.

all this and it gets 30mpg on the fwy btw ftw imho lol


Anyways.
There is a ton of aftermarket parts for these motors, they are also easy to work on.
They also make a crap load of power. They are also really responsive to mods. Check it out.
a stock 2002 ls1 makes 350hp/350tq at the flywheel.
My motor only has:
Mild cam (thunder racing 224/224)
Comp cams dual valve springs. Required for any cam swap.
Comp racing titainium retainers. Recomended for high rpm shit.
Crom-moly pushrods. Recomended if using a big cam or high hp.
March underdrive (dampened) crank pulley
160 deg t stat (needed)
JTR Headers
Reflashed ecu
Aluminum belt tensioner
Aluminum ps pulley
Hinson cold air intake
Shock Drifting 3" exhaust

With only these minor mods the motor made.
444hp at the crank. and 444tq at the crank.

On the dyno i had over 320 rwtq at 2000rpm and that peaked to 388 rwtq around 6000rpm.
The power was also impressive. 212 rwhp at 1800 rpm. and 388 rwhp at 7200rpm.

Heres some pics.
Fresh off of craigs list.

Thats a shitload of aluminum

The intake manifolds are plastic for smoother runners, and virtually no heat transfer and heat soaking.

The cam is easy as hell to change.

T56 is about the size of a z32 tranny. 6 speeds. Uses atf instead of gear oil. hmm.

Headers.

The ls1 oiling system isnt the greatest for oil pickup. i reccomend a accusump oil system.

2 of the new valve springs, and ti retainers installed.




LS1 Into S14. as you can see it sits lower then the ka, an just as far back.


Tranny has same location.
