Rb25 Into Hcr32 - Engine Mount Question

Hey guys,I've searched this topic over and over but seem to have come up short of a clear answer. I'm installing what appears to be a Series 1 RB25DET into my HCR32 and I'm unsure what the situation with the motor mounts is. Some people say just use the RB20 mounts, but I've also read that you need to swap the motor mount brackets on the RB25 engine block itself to the RB20 brackets?

Other info I heard is that RB25 motor mounts are the same and should drop right in, which clearly isn't the case because the motor does not bolt in right now and I've wasted a night trying to get this thing bolted in.

What exactly do I need to do to get this motor bolted in? I have the RB25 with RB25 engine mount brackets and RB25 engine mounts.

Can anybody who's done the swap please chime in? I'd greatly appreciate a second of your time.

You need to use the 20 engine mounts for sure & I think the brackets too.

Can't quite remember with brackets tbh but I'm pretty damn sure. But yeah 20 mounts, 100%.

From memory you can sort of tell by looking as one set will mount rather flat while the other is more angled...

Great, thanks so much guys! That's a pretty solid answer. Haha.

Here's what it's going in:

The engine was dropped in by my friend because we had nowhere to put it, so it was literally sitting on the oil pan and crossmember.

Anyway, thanks a lot, now I just need to source some brackets!

Thanks mate. The places I found that sell RB20 brackets want $80.00 plus shipping for them... So much money! I think I'm gonna have custom solid mounts made instead and just use a Nismo transmission mount...

The wheels are 18x9 +7 front and 18x10 +7 rear.

by the way my conversion to a 25 worked pretty smoothly though i had someone do it for me......biggest drama was getting speedo working really with the 25 box

      Thanks Santa (the neverending trials of the 400,000klm, 400kw, RB30, manual swapped Stagea)

      Thanks Duncan! Yeah it's street use for me only. Maybe occasional track day. Any difference in noise when running with the two pumps? I would expect the lift pump to be more quiet than the main pump so hopefully not? And yes, unfortunately quite a big price difference to the simple hanger setup. Though I'm usually willing to trade money for better reliability and future-proofing. Buy once, cry once and all that. I'd be very happy to never have to deal with fuel pump / wiring issues again

      The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p

      Bonnet clearance?

      On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.

      So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
