got the rb26 in the cefiro and went for a drive today. goes real good. extremely happy with the performance. still a few things to do exhaust, intercooler mounting, and bits and pieces, but atleast i can drive it. anyone know who does a good/cheep exhaust on the gold coast? brought it as a rear wheel drive half cut from brisbane motor imports they did very well with the service, even got some new turbos with steel wheels atfer it arrived with blown ones. was not a bad conversion every thing went to plan, spent about 30 hours on the wiring as i have used the standard computer and have connected all cefiro guages and rev counter. here is some photos.

just using the r32 rb20 gear box that came with the motor, looks like it had been recoed and has no rattles or problems. the cefiro was origanally auto and i used the front part of the skyline drive shaft with the cefiro back part of the drive shaft. no welding and very cheep way to go. had to get mechanic to undo the big nut which holds the two parts of the drive shaft together. i have written up how to manual a cefiro on this forum some where, it will be exactly the same for your skyline.

the cefiro currently has s15 lowered springs in the front and cut cefiro springs in the rear, real good fun in the wet with the extra power but would like it to handle alot better. what are your experences with different suspension set ups? are coil overs as good as every one says, should i save up for tein or get some cheaper korean jobbies? or can you get away with lowered springs and changing the shocks. would a front and rear sway bar make a good improvement. any information from your past experieces would be greatly appreciated. thanks

Thicker rear sway bar makes the IRS less independant hence more prone to oversteer, which is good if you intend to slide the car. Lowered springs and short stroke shocks are fine if they are matched properly to each other and the application. The benefit of coilovers is the ability to raise/lower the car, change the preload (depending on the coilover) and usually have adjustable camber tops/dampener settings.

I'd say save up for some decent coilovers they would probably be comparable in price to a decent set of shocks/springs.

thank you for that. i might invest a white line rear sway bar and save for some good coil overs, do you recomend changing the front one while i am there? are white line sway bars ok? thank you once again.

Mate in regards to the exaust, one of the other RB26 ceffy dudes has at least stainless dumps/fronts, he is in Brissy, and I dont think he wants to use them. I'll let him know if you are still chasing down an exaust.

thanks for all of the comments. i brought the down pipe off a mate who went single turbo on his gtr and got a second hand 3 inch exhaust off boost cruising, but thank you for the tip.

i am not mechanic but managed to do everything myself, i did pay for a guy to do the exhaust because the two systems did not line up. it cost me $4600 for the front cut, maybe $200 for fluids eg oil and anti freeze, about $500 to sort out the exhaust but that was for a whole system excluding dump pipes ( there is not too much room between the two turbos and i think the factory ones were ok. ) and that is about it. there really is no difference between doing a conversion with a rb20 or a rb26. i still need to get some sort of pod filter set up, none of the importers have any down on the gold coast, and i will get it dyno tuned as well. but that is it really for expenses. very happy with the way it goes and it is only running 8 pound, will probably not go for too much more to try and save the gear box.

dont know if anyone really cares, but here is some information on how to adapt a hicas power steering pump to work on a system that has only turns the front wheels, if that makes sence. when i am modifying things on my car i like all the info i can get.

when putting the 26 in the cefiro i used the old rb20de non hicas power steering pump which didnt line up with the main pully, so every time i gave it a burst it would throw the belt, first i packed the pullly off the power steering sharft with some washers, still threw belts, next i swapped the pump with the hicas power steering pump and blocked the rear wheel fluid line with a bolt, didnt throw belts but when it was reving hard it would leak power steering fluid everywhere, and was hard to find where the fluid was coming from. i took the bolt out which blocked the rear fluild line and wrapped it with thread seal tape, better but still leaked. next i pulled the rear of the pump apart and pulled the fins off the sharft which spun in the housing, finally works a treat, no leaks and power steering works perfect. ah yes.

next, change the fuel pump and get it dyno tuned, then it is off to willow bank.

got the rb26 dyno tuned today, started with 234 rwhp and finished with 267 rwhp on 10 psi. very happy with that, have not really got up it yet as there was too much traffic around. off to the quarter mile next. any one with simalar specs know what i should expect?

I have an RB26dett Ceffy, and hoping to get some advice from anyone else with one.

I have an issue with my steering rod as it comes throught the firewall, the angle of the rod is very sharp and it fouls on the side of the firewall hole, leaving wear on the steering rod.

The conversion was already done when I bought the car and I'm not sure if this is caused when the RB26 went in?

The steering rod first connection in the engine bay is to a solid alloy block spacer and then to a single uni joint that goes to the steering rack. It looks like there should be 2 uni joints to correct this bad angle I have coming out from the firewall??

Can anyone confirm if there is 1 or 2 uni joints for the steering in the engine bay?

I think that maybe one of the uni's was worn and it was just replaced with a solid block of alloy to save money.

Any help appreciated.

Rgds

      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:
