hey everyone, i got the oppotunity to pick up a good rb25 with box for a real cheap price, but was wondering how hard it is to fit into my r32. is it a straight swap or do the mounts have to be modified? one guy said it cost 7000 all up to do the conversion in his r32, does this sound about right? i have all the rb25 electrics (loom, computer, coils, etc). any help much appriciated!

anyone got anymore information on this

the crossmember i cant see lining up due to the difference in length of the gearbox's and the speedo on the rb25det gearbox is also electronic rather than the mechanical of the rb20det + the tailshaft is also different?

You have to get a tailshaft adapted for the rb25 box (standard rb20 tailshaft welded to rb25 yoke (end spline)), and also a custom crossmember made up. Both of which should only cost you a few hundred dollars all up. When you have it all the box and engine in there it will all make sense what you will need to make that all work.

Been covered many times. I even included it in my thing.. So I don't know what info you need other than getting one made up??

7. If using rb20 box, just use standard r32 speedo cable to get speedo to work fine. Otherwise use the top r32/bottom r33 sensor method to rig up rb25 box

5. Going from auto rb20 to manual + rb25, I need a custom gearbox mount fabricated, as only 2x bolts line up.

    • Hello everyone. I believe I have s1 headlights but I just wanted to make sure and getting confirmation from you all. Thanks in advance for your help!
    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy.
