robopineapple Posted August 16, 2014 Report Share Posted August 16, 2014 Im so lost haha... soooo it will work, its just a slightly different gear ratio and different custom cross member and drive line right? Quote Link to comment
datzenmike Posted August 16, 2014 Report Share Posted August 16, 2014 Driveshaft? An automatic driveshaft may work. Check into it. Maybe. You have an auto or standard. If standard your driveshaft is going to be too long no matter what 5 speed you put in it. I believe the A10 automatic is 31.5" long so an auto driveshaft will be shorter than your 4 speed one. As the D21 pictured is 30.75" that's only 3/4" shorter than perfect. I'm saying that D-21 5 speed with an A10 auto driveshaft should fit or be very close. Quote Link to comment
flatcat19 Posted August 16, 2014 Report Share Posted August 16, 2014 You can do it. It's just nuts and bolts. And you have so much support around you locally. I'd love to trade you cross members, just to make it a little bit more simple for ya. You got this. Quote Link to comment
robopineapple Posted August 16, 2014 Report Share Posted August 16, 2014 How would your cross member be easier? How long would my drive shaft have to be to run that tranny? Quote Link to comment
datzenmike Posted August 16, 2014 Report Share Posted August 16, 2014 I assume you have the 4 speed? It's 26.5" long. I assume the same car but with a 3N71B automatic is 31.5" long. Most L series auto are. Same car but two different length driveshafts. That D21 5 speed is supposedly is 30.75" long which is only 0.75" shorter than the A10 automatic. Thus an A10 automatic driveshaft should be very close to a good fit. This is what I did on my 710. The 4 speed is 26.5 and the auto is 31.5. I swapped a 31.5" FS5W71B 5 speed in and used the shorter automatic driveshaft. Perfect fit. 4 speed..................................driveshaft.......................differential 3 speed automatic.................driveshaft.......................differential FS5W71C 5 spd ..................driveshaft.......................differential (barely 0.75" short) .

flatcat19 Posted August 16, 2014 Report Share Posted August 16, 2014 My cross member came from a Z'd A10. Yours has an L. KA leans the same way as the Z. I've been led to believe that they are different; Or that the L/Z mounts are different. But I have no proof. Quote Link to comment
datzenmike Posted August 16, 2014 Report Share Posted August 16, 2014 A10 front engine crossmember? Should be the same, L or Z series engine. It's the engine brackets that bolt to the rubber mounts on the crossmember that hold the engine in the correct L or Z series tilt. Quote Link to comment
robopineapple Posted August 16, 2014 Report Share Posted August 16, 2014 I have a five speed manual on my l20 Quote Link to comment
datzenmike Posted August 16, 2014 Report Share Posted August 16, 2014 So dogleg? Quote Link to comment
robopineapple Posted August 16, 2014 Report Share Posted August 16, 2014 Reverse under fifth is dogleg right? if so, then yes Quote Link to comment
datzenmike Posted August 16, 2014 Report Share Posted August 16, 2014 No this... R..2..4 1..3..5 OK so you have an FS5W71B. If from a 280z or zx, 810/Maxima or 620 truck it's 31.5" long and that D21 should be close enough to use the driveshaft you have now. Quote Link to comment

mhub91 Posted August 16, 2014 Report Share Posted August 16, 2014 Zach, considering I've done this exact swap..... Don't worry... I've got you covered. I can help in every way possible. I have templates for the cross member for use with the 240sx 5 speed (FS5W71C) And shortening a driveshaft would be the best way to do it. I agree with Datzenmike where the auto driveline is very close, but 3/4 of an inch, or (23.6mm for those in Canada :poke: :rofl: ) might be all the difference in causing a nasty vibration and eventually causing your tranny to blow. Please, ask me how I know.................. Anywhoo, don't be intimidated by this project. It's extremely simple. I did this all by myself with only the drive shaft being made and a few questions answered here on Ratsun. 2 Quote Link to comment
robopineapple Posted August 16, 2014 Report Share Posted August 16, 2014 Im not to worried about it, i know all of you are willing to help a brother out haha. sourcing a tranny is the only thing, thts the only one i have found xD Quote Link to comment
datzenmike Posted August 16, 2014 Report Share Posted August 16, 2014 I say that 3/4" is close and it will work. Dime owners that swap to long tail 71B 5 speeds in their goons can fit a sedan driveshaft. It is 1.3" short but works perfectly. Quote Link to comment
datsunfreak Posted August 16, 2014 Report Share Posted August 16, 2014 Dime owners that swap to long tail 71B 5 speeds in their goons can fit a sedan driveshaft. It is 1.3" short but works perfectly. Done this. Worked fine. Lengthened the dust shield 1" though. Think I may have been the first person to do this. :rofl: Your mileage may vary... Quote Link to comment
datsunfreak Posted August 16, 2014 Report Share Posted August 16, 2014 A10 front engine crossmember? Should be the same, L or Z series engine. It's the engine brackets that bolt to the rubber mounts on the crossmember that hold the engine in the correct L or Z series tilt. I can confirm they are identical. Had both side by side. Just the engine brackets are different. Quote Link to comment
flatcat19 Posted August 17, 2014 Report Share Posted August 17, 2014 I can confirm they are identical. Had both side by side. Just the engine brackets are different. Want to trade brackets then? My Z brackets for your L brackets? Quote Link to comment
mhub91 Posted August 20, 2014 Report Share Posted August 20, 2014 Terminology error here.... If L is slanted to the right (passenger side) due to the brackets. The horns on the xmember are identical. Infact, crossmembers are identical between the Z and L series A10s. Quote Link to comment
flatcat19 Posted August 22, 2014 Report Share Posted August 22, 2014 And then? That had already been sorted out. A10 guys...Need L A10 brackets for my 210 L swap. Quote Link to comment

bananahamuck Posted August 23, 2014 Report Share Posted August 23, 2014 It's kind of a coincidence that FAT is complaining about 210s and we went to a house where we were literally surrounded by them this afternoon. :lol: Quote Link to comment
