Here is my RB25DE that we picked up yesterday.. it ended up being out of a r33 not a r32 like we thought..

Bridgestone Potenza front coil overs and springs.. & JIC rears...

New upper and lower nismo control arms..

Coilovers & upper control arms intalled..

Lower control arms installed..

I will keep this thread up to date with he conversion.

:laugh: I'm SO excited!!!

so your going to turbo the NA motor?

Yes that's right!

hmmm 33 na 25 is going to make things a little harder yes?

Yes correct... i was actually wanting to get the non vvt rb25 but this is the one we ended up with...

I didn't even know Bridgestone made coilovers

Are you going to leave the motor as a high comp. NA when you turbo it?

I didn't know they made them either!

We are putting a 2.4mm head gasket to lower the compresion down quite a bit.

hey matey

im doing exactly the same conversion...

right now actually.

i've got my 25DE sump at the engineers getting the 20DET oil drain welded into it.

Other than that, im gonna rock the 10:1 CR and the 260 cc injectors with the stock RB20 ECU, stock turbo and manifold and im gonna use a 1980's apex AFC to richen things up a bit.

by they way, im gonna be running natural boost and aiming for around 160 kw at the wheels

That sounds interesting andy! Can i ask why you aren't using a thicker head gasket to lower the compression? I was told that is the first mistake most people make when doing this conversion.

I have a Blitz access computer going on mine and some GTR injectors..

I am using the RB20 manifold and bits of my old engine..

and an RB25 Neo turbo (for now that is) :happy:

andy,

ermm... whats natural boost? :happy:

You mean standard boost, i.e no aftermarket boost control apart from the std actuator?

and yes lowering the compression via the thick headgasket works but it does increase fuel consumption and makes the motor detonate easier.

With regards to the rocker covers thing.. My R32 RB25DE (nonvct) looks identical to my RB20DET. The only way you can tell it apart is by looking at the size of the valves, combustion chamber and ports. So once its bolted on you can't tell the difference between the rb20 and rb25.

so are you using the stock rb20, or rb25 turbo? if its the rb20 i think you would be better off with the 25 turbo, as it isn't going to be as close to maxing out... unless you don't plan reving over 5000rpm.

    • 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:
