No real updates yet....I've finished the headers and I'm almost done with the Y-pipe. The clutch line is done but I'm waiting on the master cylinder..basically that's the last piece that I need before I can drive the car. There's a bunch of little things to finish up but nothing that will keep me from driving the car. I'll post pictures of the finished headers tomorrow evening...I'll be driving it by the middle of next week! FYI...Hinson now sells a master cylinder and clutch line for the 240sx LS1 swap at a very reasonable price.

Ya the hinson kit seems like the way to go.
And for a cheap way around headers the ford 302/351 have the same bore spacing as the LS1! So both mustang fuel rails, and headers will work! Most mustang headers are made for kind of a cathedral port like the LS1s intake, so you'd have to use new flanges, and make them more round. The mustang fuel rails just get flipped 180 degrees to match up the angles of the injectors. Pretty sweet cuz mustang parts are CHEAP. Oh, same bolt pattern on the wheels too! Swap swap swap.

Hmm...I can get a 89 240sx with a blown motor for real cheap...This looks like a possible canidate for my LS-1...
My question is...how strong are the rear ends in the 240sx...?
I will most likely be drag racing it a lot...I will be using a t-350 transmission with out a trans brake so the should cushion the hit to the rear end a little.

Having owned 4 240's now, i can say they are actually pretty strong rear end. The problem you will have being an s13, is its an open diff rear end. So you will get the infamous 1 tire fire. There are ways around it though. The 95-98 240 se's had a vlsd as an option. This has been said a very good way to go for around or under 400hp. I had a 95 240sx with and sr20det, that made around 300hp, and 330 torque, and never had a problem witht he vlsd stock in the s14. You can pick up a j30vlsd or 240sx vlsd for usually around 300 bucks. If you would like ti a little stonger you can go with a 300zx rear end. I believe the na ones have like a 3.73 gear, and the twin turbo ones have a 4.09 gear. Not 100% sure on gearing for 300zx but its similiar to that. Rear end should go in pretty easy, and you could possibly convert to 5 lug in the back then so you have more rim option, as the stock s13 will be 4x114.5. The 300zx rear end has been known to hold on several 500 and 600hp cars. If you still need a stronger rear end, the kaaz lsd will drop in the non lsd s13. THe kaaz unit has a pretty good warranty and has been said to hold up to 800 hp. At this point you would need some chromoly axles which can be had for around 400 bucks, and you shoudl be good to go. Lastly the option i would go is go with a r200 rear end, and put a quaife in it. Quaife lsd's are warrantied for life, even under racing. If you brek it they replace it, it is around the same price 1k, i am just not completly sure if the stock 240 rear end is considered and r200 or not. Still gota look into this. Hope this helped. Pm me, and i can give you a bunch of links to buy the rear end stuff for 240's. Dont want to post really cause there not sponsers.

I have had over 300 foot pounds of torque to a vlsd, but yea like u said it was made up higher in the rpm range. I have never personally owned an ls1, nor one in a 240. If it breaks, i wil rebuild it stronger. BTW the limeaide 240sx which is an auto ls1 has had the stock open diff rear end for a while in it. I actually was interested in buying the car. The car has been to the track several times, and no rear end problems yet. Ps, lemme know how the driveablity is on the welded rear end? how will cornering be? lemme know, Thanks, Chris

the r200 is the stock 240sx, j30 and 300z n/a rear end. the 300z turbo rearend is a r220, and will not fit in a 240 stock subfrme. the 200 has a 200mm ring gear while the 220 has a 220mm ring gear....hence the stronger of the 2 is the larger unit. gt-r skylines use the r220 and hold a crap load of power, so if swapping the entire subframe out of a z turbo into the s chasis is possible you will open up unlimited axle diff choices.

Dakota Digital.
I just welded my diff today and drives AWESOME. Around turns I can barely even tell. I have to cut the wheel all the way and go slow to feel it but other than that its fine. It still spins like crazy since I have snow tires on it which were on it when I bought it. Welded diff, sticky tires and it should pull 1.6x 60's. Thats if nothing breaks lol.

ive ruined a vlsd with a stock ka. when you run bigger than 195's out back (in my case 245's) and spin the rear tires a lot going around a corner the vlsd doesnt like it.
my drift car is running a welded diff, and it has held up so far.

ugh, or you can just change out the axles and run the r220
my setup is welded stock r200 diff that came in the car, drive shaft shop axles, built t56, and hinson driveshaft, ive had zero problems, thats runnin cooper zeon 2xs @ <20psi 275/35r18 on triple chrome foose wheels, with a ls1, with a supercharger, on sticky pavement

the axles you use j30, im not sure what rear cover you use. that *looks* like it woudl work on a s14, the s13 uses 4 bolts that directly mount to the subframe and no bushings on the front IIRC, the s14 uses 2 boltson the rear cover with bushings, and has 2 bushings on the front of the housing IIRC , i might be backwards, but there is a way to mix and match S chassis, j30 and Z32 parts to make the Z32 diff a bolt on affair.
