Rb30 in s13, crossmember plus a few questions

Hello guys I know there are a few topics on this but no definite answer was given. I currently have a rb25 in my s13 on a r32 gtst crossmember and engine mounts and bonnet clearance is pretty tight as is. Now the rb30 engine is taller and will definitely fowl on the bonnet. Is the rb30 38mm taller or 30mm taller as I have been told both? And from the other topics I've seen the r32 crossmember is the lowest crossmember you can use. The problem I'm finding is if I lower the engine using the mounts the sump is going to fowl on the steering rack before I can get it low enough. Would using the s13 crossmember be better? Is it lower than a r32 one?

 

Thankyou for any help that c an be given on this subject

r32 engine brackets, cortina engine mounts

Hi thankyou for the reply I had seen this combination before. Do the engine mounts lower the engine that much then? As im already using the r32 stuff and didn't think the r32 engine mounts were that big to begin with.

 

I also found this thread:

https://www.driftworks.com/forum/threads/the-definitive-nissan-crossmember-thread.243198/

which was quite interesting and when it comes to the crossmember itself it would appear the r33 crossmember sits the lowest. But this doesn't take in to consideration the size of the engine mounts.

 

Thanks again mike

how much room are you chasing?

when i did mine (5years ago so hard to remember) i thought r33 stuff sat engine forward and higher and r32 sat back and lower... either way i dont think there is a great deal in it. i ended up shortening engine brackets as i had 25/30 to get bonnet to clear

Hi sorry for the delayed response I haven't been able to log in to sau on Tapatalk for some reason. I'm ideally looking to gain the extra height of the rb30 block. So atleast 38mm. The problem I'm finding is the sump will hit the steering rack before I can lower it the required ammount

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
