Yes. Due to the pointy nose of the 32 it tends to hit on the bonnet. You'll need to either raise your bonnet (or hack it), lower the subframe, leave off the cam gear cover (I think??) or a combination of those.

Don't let that put you off. There should be a fair bit of info on the issues in RB30 conversion thread.

Hi guys, the last 30/26 I was purchasing fell through... I'm looking at another now but it is in a 33gtst (rwd). What will I need to do to it to get it into my 32gtr. Will it just be a sump adapter? Thanks, Jonathan.

There is a fair bit of work fitting the sump adapter - drilling and tapping and grinding. A couple of bell housing boltholes will not line up and you have the choice of welding up the old ones and drilling and tapping new ones or just leaving them out.

dont leave the bolts out.

unless you weld the sump on, the extra height is going to cause the gearbox bolts to be out.

DONT WELD THE SUMP ON.

the extra deck height is a problem.

elongate the engine mount bracket holes, and drop the engine closer to the subframe.

if using a small turbo or low mounts, you should be able to get away with trimming the bracing from under the bonnet.

I have personally spaced the subframe.

mainly because I didnt want to touch my bonnet.

keep in mind, if you go this route, the cooling fan will no longer line up.

but, the guard to plenum pipe should.

Dont forget if your running a aftermarket plenum that it may hit the clutch booster.

I had fun with that one today, ended up converting a S14 clutch master to bolt straight on without a booster, built a adapter so i would not have to redrill the firewall......

Ok cool, valuable advice. Cheers!

Also, I have a guarage 101 extended sump (rb26) with a pickup. Will this pickup work on the 30 bottom end?

No, you'll still need to get the pickup modified or it will sit 10mm too high in the sump. The adapter spaces the sump down 10mm regardless of what sump you use.

Ah bugger, ok I'll have to look into that in more detail. Cheers

Yeh I'm going to be running a stock plenum so that will not be an issue.

does the extended sump use a standard pick up?

if so, just use the modded pick up.

if not, will have to be custom made/modified.

I didnt ;)

one more advantage to the spacers.

I have to get a thread up and happening.

R32 GTR with a 26/30 and with a Greddy Plenum and the original throttle bodies?

How much room was left?

Where are the closest points and distances?

Im also going to run the spacers but didnt think it was enough to clear the Clutch master.

Still not too late to drop the original master and booster in.....

yes, genuine greddy.

original throttles and sandwich.

plenty of room.

but, if using spacers, can no longer run stock fan.

have to go thermo.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
