I have 2 x 1985 mr30 skylines with the l24e motors in them,

1 auto and 1 manual.

I want to convert the auto into a manual as the body, motor and various other parts of the car are in better condition.

So i have all the parts required, my question is am i going to run into issues with this swap over, eg. different crankshafts in the motors? or bell housing mounts on the motor?

Press the search button and you will find information about this conversion.

From memory, the biggest hurdle is the different rear gearbox mount, but engines are same except for pivot bush in the back of the crank & bellhousing mounts are same no matter if using a 4 or 6cyl front housing.

Thanks for the reply, I'd been searching for hours, but obviously using the wrong search criteria.

I was specifically looking for r30 but now have found the topic of the swap in a c210 wich is pretty much the same thing i suppose.

That topic also had this link

Which is a work log of a similar swap on a Datun 240k

also did this swap with my c210. there pretty damn similar bro so my write-up might help you

Thanks for that, looks to be very heapful.

I finally found the topic Ghostrider was talking about.

After reading that I'm devastated, i need to fabricate a crossmember!!! damn it.

I was planning on getting the swap of all my gear from the manual body to the auto body this long weekend.:(

Has anyone got a pic or a design for a gearbox crossmember for the mr30 gearbox swap?

Almost Done with the full conversion,box is in (cross-member not done yet :( )

But i have run into a wiring problem, which wires do i need to connect together on the auto wire harness to make the stater motor turn over???

ie. the switch that tells the motor the engine is in park???

And which ones are the reverse lights???

there are two wires on the manual gearbox for the reverse lights.

On the auto there is 4 plugs, one with a 4-pin connector which goes into the side of the shifter on one side of the box,

and on the other side of the box are 2 x 2-pin connectors and 1 single pin connector.

So at a guess one of the connectors on the auto harness is for the overdrive switch (4-pin as the switch had 4 wires),

one for reverse lights (2-pin), one for park so the engine will turn over (2-pin) and the other single wire connector is an earth?

Please help, or i will need to get my hands on a multimeter and spend a few hours working it out.

Also i have been told that i need to change the ecu and the diff as well is this true???

regards modbox.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.

      It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
