a few more things to add as in converting my car at the moment (not on a hoist unfortutaly)

make sure u install the brake pedal first and i did the clutch and i couldnt move the brake around enough to get it out so just ended up losening it off and unbolting the pedal itself and putting the manual pedal in the old bracket.

a realy realy super long extention is the only way u will ever get those top bolts on the gearbox out, and the starter motor in a pain for the top bolt to.

tommorow i get to take on the spigot bush...how fun

my gearbox cross memember bolted right up :S

yet i cant get the clutch to bleed

:rolleyes:

edit after 20 times or so it finaly bleed properly, now the tail shaft center bearing is screwed, should of cheaked better

yet i found out why the crossmember bolted up, looked at the tag from the halfcut, and it says the car was an auto, so it was converted in japan, so thats why it fit, someone modified it already.

More useful information (4 door conversion):

I used an S13 cross member for my conversion, bolted straight up

A thing to note, if you have a 4 door you will need to use the original Rear tail shaft section as the coup rear section is about 2 inches too long.

Both the NA RB20DE auto and RB20DE manual runs a smaller bolts between the 2 sections on the tailshaft. NA has smaller 10mm bolts and the turbo Auto and turbo Manual has 14mm bolts, also the plate sizes are different.

I ended up unbolting the Spline bolt on the front section and swapping the Plate over, so mine was turbo spec.

now i have a question, whats the best way of doing the manual loom? Cutting up an auto one? Which wires do i use at the Fuse box?

Wiring:

Ok so i got mine all sorted, The Reverse plug is the Front plug (NOT THE ONE NEAR THE SHIFTER)....just grab your old loom off the auto, cut all wires except the ones as mentioned in the first post (Hand drawn picture)....run them down to the centre plug (both wires on mine were green and black), trip them and test to see if the rear reverse lights come on when you select revers and thats about it.

the loop wire for the neutral is just on the same plug, loop the 2 wires over.

Thanks alot man, This is really helpful.

I will be doing my R32 Manual conversion soon..Just not sure if its worth doing my self. I have never done one before, but I have basic mechanical knowledge, your info cleared alot of things up.

Only pain I can think of is the clutch pedal? are the R32 ones hydrolic? or cable? is it hard to do?

Thanks a bunch for sharing mate.

Extra piece of info, you can use a S13 sr20 gearbox mount.

Its basically the same as a 32 item but backwards, ie the hump in the mount is on the other side so once you turn it round and install it backwards so the holes line up and the hump ends up being on the correct side..

You will know what im talking about when u see them.

Just starting a conversion from rb20det auto 4-door to rb25de+t with rb25det manual gearbox (yes can you choose any bigger a headfeck?).

To confirm I should just find an S13 SR20 manual gearbox crossmember for easiest mounting solution?

What do I need to get the tail shaft to be the right length?

What is the current best option for speed sensor?

Would it be better to bolt on the gearbox while it is out of the car?

Folks, one question regarding the pedals, I had a look and don't see how it's possible to take out and refit the pedals while the dash's still in.

Is there a way to put them while the dash is in?

Would love some answers today.

Cheerio

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
