Alright so i almost got all the things i need for my 5 speed swap, so far i got

-5 Speed Transmission
-Transmission Mount
-Transmission Cross Member Bracket
-Used Clutch and Pressure Plate
-Pressure Plate Bolts
-Flywheel
-Flywheel Bolts
-Engine Mid Plate "Dust Shield"
-Brake Pedal
-5-Speed ECU
-5-Speed Lower Harness
-Steel Clutch Hard Line .
-Used Slave Cylinder
-Clutch Master Cylinder
-Clutch Hose
-Shifter
-shift boot

so i was talking to a general mechanic that i know and he told me that i was going to have to get a different radiatior as well. Is that true??

also i currently have the HUD digital cluster on my whip. im i going to need to change that to to regular gauges? and will a sohc ECU work on a dohc?

thanks alot

sohc cluster wont work dohc and the radiatior dosent have to be change but you should get and auto ecu there no rev limit on an auto one but 5 speed ecu dose have a limit..

No, auto radiator has a built in tranny cooler is my guess why he said that, But you dont need to get a new one, just undo the lines for the tranny coming off of it and it will work perfect, Also no the SOHC will not work on the DOHC, but if you cant find a DOHC 5 speed ECU your auto ECU will work just fine.

no sohc on a dual cam will work properly. Gauge cluster you could actually just swap out your tach for a dual cam tach. The speedo will work fine.

as for your radiator just drain out the tranny cooler section. if you want you could turn that into a oil cooler.

Also you do not need the 5 speed lower harness on the s13 because the only things you need to wire up are the reverse lights and your speed sensor.

check out the Auto to 5 speed swap in archive and faq section.

240sxrb25 · 04-26-2010, 11:02 AM

id still use the auto radiator cause they cool better as i hear. full metal construction rather than the plasic top 5 speed ones.

sectorjeff · 04-26-2010, 12:05 PM

thanks guys that dude had me confused lol.
now i just need my drive shaft and a clutch pedal to start swappin

hittin up the junk yard for that in a munite[IMG]file:///C:/Users/JEFF/AppData/Local/Temp/moz-screenshot.png[/IMG]

g6civcx · 04-26-2010, 03:12 PM

I was going to say clutch pedal.

For driveshaft you should get a Driveshaft Shop driveshaft since most of the used ones have broken center carrier bearing.

You need to jumper the inhibitor switch harness next to the battery so you can start the car.

You reuse the auto lower harness and hook up reverse and speed to the manual sensors.

No other sensor is needed on the lower harness.

Trejo_andy · 04-28-2010, 12:05 PM

How Much did u pay for all the parts to do the swap? cuz i am looking to do the same thing

joshchewuhh · 04-28-2010, 12:14 PM

I wouldnt get the auto ecu its really annoying when your coming to a stop its stays at like 1500 rpms and slowly drops to idle

lazysk8er2 · 04-28-2010, 07:15 PM

wow nicest responses consider yourself lucky these guys are helping you.

also that oil cooler idea through the rad is not a bad idea. wish my koyo had that option

shanes14 · 04-28-2010, 07:18 PM

you do NOT need the 5 speed trans harness. it will just give you a headache. your speedo wont work and a bunch of bull. leave your auto harness in there and just hook up your speedo for instant work-age . then pm me if you want and ill walk you thru the wiring of your reverse lights and other things.

sectorjeff · 05-01-2010, 01:18 AM

Awsome info guys thanks a lot I didn't get any b.s lol
Oh and I got the swap for 390 everything except the clutch pedal and drive shaft. And also thanks bro ill hit you up if I need wiring help.

Sileighty_85 · 05-01-2010, 01:40 AM

OP you need to search there are countless threads and walkthroughs on doing this

having said that

you dont neeed to swap the brake pedal just the the brake pedal to size.

Also you need to make sure you swap out the Pilot bearing for a Manual tranny one.

shanes14 · 05-02-2010, 10:42 AM

i did countless searches and coudlnt find anything that said not to use m/t harness. but i just cut my brake pedal. still havent gotten a 5 spd one yet lol

sectorjeff · 05-02-2010, 02:27 PM

got the drive shaft and the clutch pedal assembly at the junk yard today for $50 and a clean ass dash for only $19 chea boi came up

93nismo · 05-02-2010, 03:47 PM

for the reverse lights all you have to do is solder some wire onto the leads on the sensor and splice it into the wires for the lights. just find the color of the wires and ul be set.

Trejo_andy · 05-14-2010, 02:03 PM

Did u buy all ur parts from a junkyard or did u get them from a store?

all the junkyards around me have autos

g6civcx · 05-14-2010, 02:23 PM

The lower harness is confusing as hell. Nissan made like 2 dozen different variations of KA lower harnesses.

The best thing is to reuse your auto lower harness. Eliminate what's not needed. Hardwire in the VSS and reverse switch into your auto harness.

Trying to make the manual lower harness work with the auto body harness is a nightmare.

sectorjeff · 05-17-2010, 12:43 AM

thats what im gonna end up doin. would the plugs fit the manual tranny the same as it would to a auto tranny tho?

shanes14 · 05-17-2010, 06:05 PM

no. u will have to pinpoint them. you only need like 3 or 4 wires. i had a little more sinse im a vert with cruise control, but u will need to keep the green and black wire(they are reverse lights. doesnt matter which way you hook them up, as long as they are attached to each of the reverse switch thing, itll work. the speed sensor just plugs in. no wiring. i dont think theres any other wires. have you already cut the harness to get it to crank?. if not then there is a two plug harness(i think one is brown, the other wires is a tad bit smaller i think. its been a while). cut it off the tranny and sauder or twist the two wires together and just plug them back in.
