I'm looking for a project car to drop an RB25de into which I picked up relatively cheap. I spotted a very reasonably price R30 hatch today which I had never considered before. After some searching I can find surprisingly little information about these cars. What suspension is in the rear? How difficult would an RB conversion be? Are they notorious or something? All I've heard is that diffs can be difficult to source.

diff can be slightly harder than average to find, but really only if you are trying to find a factory lsd.

heres a tip: 720 4wd ute had a r180 diff in the front end.(nice low ratio too, 4.8) serious acceleration for a low power engine like an rb25de

main problem though with the MR30 hatch......they are ugly.(makes for a good sleeper)

ahhh the age old RB coversion thread....

it isnt overly complex to do, about 6 or so members here have done it, 20/25/30...

I think we need to get the mpderator of this sectio to make the rb convo a 'sticky' thread that always stays at the top of the list/.

Basic outline.

Use R31 engine x-member and gearbox x-member

need shortened tailshaft to suit, or a Nissan Bluebird TRX (RWD) 'need to confirm'

use RB engine mount on passenger side, l-series on drivers side

cos i havent done it myself (yet) this is all just what i remember over the last few years

if you get a Ti Hatch, you get disk brake rear end,

there are plenty of threads on here, just search...

RMR30's are not ugly. They may appear ugly to jealous bastards who have never had the joy of owning one,or two.

Also I had a 720 King Cab, never Knew they came in 4WD.

oh but i DID own one......i put the drivetrain into my c210 and chopped it up into little bits and took it to the dump.

mainly because it was ugly :)

I'll settle for this!

Better than being FUGLY as the C210 coupe is.

Wonder how you would describe the R34 Jase?

D

These looks nice, but the MR30 Hatch looks ugly. (I've wrecked one)

I'm not going to mention the C210, as you might pick on my C110 :-)

Aha awesome thanks guys does sound like a pretty good idea then. I really want to do a similar thing to a C110 but given the rarity of these things i'm sort of itching to put this motor in something.

I used to hate the look of them too tbh but the idea of IRS, P/S, and a nice reving RB25 for "relatively" little work and yea it would be a cute little sleeper :).

Also +1 for sticky. I think there should be sticky for all the old skylines 'conversion' given that RB's are a pretty obvious choice and i've seen quite a few especially in japan.

Just a comment on the pic (a few posts above).

I think the red over black colour scheme works well because it makes the body shape look less bulky. (There are some nice examples of white, silver or blue over black in the old R30 Pic Thread). A good colour scheme could reduce the 'ugliness' factor.

my flatmate has a manual hatch, its actually a really nice car to drive. the engine is so nice and smooth and the irs is like driving a big couch.

its for sale too if anyones looking for one, VGC mechanically, just lots of dints and rust in the tyre well, it will pass a rwc easy if you can find someone who doesnt mind rust lol

well i dont own any c210s anymore, but I agree the c210 coupe is ugly, but that doesnt detract from the coolness.

i like the 2door and 4door variants of the r30, just not the hatch, i think its a poor effort on nissans part.

( i like r34 gt-r, not so much the gt-t)

cheers

Just for the record ...... L series sound awesome when they're tweeked a bit.

I know you said you have an RB25 but how would you like about 500Nm + to play with?

Cheers, D

Yeah I agree L series engines are awesome. But if you had a 80000km RB25 neo out of an R34 to play with.. what would you do? :P .

Probably sell it, as I did with the one I had, along with all the go fast bits I had to go with it. But my reasons were a little diferrent to yours, as the PNV is a bit rare it was a stupid move converting it to RB, best to get a whole lot of fun from an L series.

But if your going with it, there is a guy on here, lives in Melbourne and has an R30 sedan with an RB30et in it that would give you all the info you would need.

Cheers, D

    • 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?
