Almost a month ago a bought a 1990 240sx pop up.Its automatic which is fine but id really like to have it manual.Ive done a lot of research about swapping the transmission i just came here to ask and hopefully get responses on my 2 questions.
1.Will a Sr transmission fit the Ka24e....I do know people done it with the Ka24de and yea technically the block should be the same but i just want to double check if anyone knows something.
2.What else am i missing to do the complete swap.Im aware that ill need the transmission,driveshaft,new clutch pedal,Clutch and flywheel and other little things so if im missing sum or you can give me advice about it i appreciate it.

Re: Auto to Manual 240sx with a Ka24e
1) NO. The SR and KA bellhousings are different. While the guts of the transmission are virtually the same, you'll have to get an MT bellhousing from a KA regardless so, why not just get the whole transmission? to clarify, an SR20 transmission will not bolt straight up to a KA engine. The bellhousings are diffrerent.

2) you'll need some brake fluid, you'll need a throwout bearing and pilot bushing (I generally don't use the pilot bushings that come w/ the clutch kits. SKF makes a nice one for cheap. You can find them at Advance or Rockauto.) I'd get some good axle grease to lube up the clutch fork pivot and LIGHTLY grease the input shaft before you install the transmission. I'm fond of Redline CV2. It'll come in handy for quite a few other small things around the garage too. https://www.redlineoil.com/cv-2-grease You'll also have to remove the pilot bushing that's currently installed in your crank. THAT is going to be a real PITA from what I understand.
You'll need a clutch line. I'd get a quality braided unit from the start. GKtech makes great products. I've got their braided line in my S14 and love it. There are certainly other places out there that make/sell these, just plugging my favorite. https://us.gktech.com/s13-s14-s15-braid ... line-lhd11 (You'd want the one with the damper delete, since your car doesn't have the clutch damper on it.)
You'll need a master and slave clutch cylinder as well. https://www.rockauto.com/en/catalog/nis ... ion-manual
You've also got some wiring to do once all of that is done. https://www.nicoclub.com/archives/autom ... -swap.html
