What do you guys think? I've seen this conversion at some shows here, and I think just from weight distribution alone it would be a good idea.

Right now I've just just got a stock shitter R32 4-door Type M... 100,000k's, couple of dings here and there, but this ones gonna be my long-term ride... hello engine swap.

Would anybody contemplate removing an RB from a Skyline?

Why would people say it's going backwards? The capacity is the same, the SR (chosen carefully) would be a newer engine, the power is virtually the same...

Alot of guys here in Japan either bomb the crap out of the RB20, or get rid of it.

the torque thing is a bit misguided.

YES the SR20DET makes more torque than the RB20DET.

SR = 155kw@6000rpm and 275NM@4000rpm at 8psi boost (ROUGH numbers)

RB = 158kw@6200rpm and 263NM@3200rpm at 8-9psi boost (rough numbers again)

the RB makes like 10NM less but at 800rpm earlier.

so whish engine is actually the more TORQUEY engine?

the one that has a little more torque or the one that pulls from lower revs?

hope this adds to the discussion.

I saw this conversion done in Japan while I was over there ( Osaka ) and it seems the main reason for doing this RB to SR swap is for race or drift purposes. The main thing is that when an SR is fitted, there's so much room between the radiator and the engine that you can bring the radiator and intercooler back into the engine bay for protection against front end damage.

Most of the ones I saw then ducted the air path up through the bonnet which keeps the air heated air flow away from the engine itself but about 1/3 of the air hitting the front of the car actually goes into the engine bay.

One of the guys I spoke to over there also swears by the reduction in front end weight and the great change in weight distribution. So if your RB is dead, go an SR instead !

Yeah, that flat-mounted-in-the-engine bay intercooler setup is a definate goer... theres actually a flat-mount intercooler for 180SX's with extemely short pipes to and from the turbo/intake manifold which I'm looking to export to Oz.

FAT32> I'm in Osaka/Kobe. Who did you speak to?

Rezz, I was talking to one guy at the Osaka Auto Messe who spoke english rather well and that's where I got most of my info from. Didn't really talk to any workshops etc. about this subject. ( Don't speak enough Japanese to hold a conversation ).

I love the conversion from RB to SR it just makes so much sense and it looked awesome in his red drift R32 !!

Was that this years Messe, or last (or one before that)? Mate, I saw a couple of Aussies (I can tell a countryman in a crowd of Japs no problem!:) ) there, I wonder if it was you?

Anyways, I love the conversion too, ESPECIALLY after Nismo retired the RB26 in the '02 JGTC in favour of the VG30DETT, for better weight distribution amongst other things...

I went this year ( Feb 03 ) and I should be going again next Feb if all goes well. The year before I went to the Auto Salon in Tokyo but that's just too packed for me. You know, you probably did see me there. I think I was causing a bit of a disturbance by drawing the promo girls away from the hungry flocks of Japanese camera jockey's. He, he. :D Got some great pictures from that trip.

I've got a mate who lives over there called Alan then another mate called Gary who also joined us. 2 Aussies and a Greek in Japan, way too funny !

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
