I'm going to have the same problem, as my R33 gearbox mount is about 150mm further back than standard.

I am making a "C" type mount that carries the original g/box mount on a box section piece of RHS having about 4 mm plates going back to the original mount points braced with a web section fillet.

Just have to get under it and design it, put it on paper and get someone, any welding/pressure vessel shop to make it for you. About any Sheet Metal/Engineering Shop will be able to point you in the right direction if they can't do it themselves.

ok, cheers for that mate, ill let you know what i come with :D

i also thought about dropping bolts through the floor so the mount lines up with the xmember... ?

If you do that, make sure the holes are reinforced, because with continual driving and some hard launching, they will tear out of the floor, making a bigger problem than the initial one you have now.

Might be better to use the orig and mount back to them

ANYTHING will fit if you try hard enough.

I put my SAAS seats, on a piece of 12mm aircraft grade aluminium sheat and then mounted the runners to the same sheet, that way I still had some adjustment front to rear.

I removed the height adjustment as I needed to lower the seating position about 100mm to allow me to sit in the car with a helmet on.

I am going to experiment with R31 seat tracks, as the height adjustment is on the track and not in the seat.

I have a set (pair) of Z32 import seats if anyones interested, they have a fully electric drivers seat. forward & aft, height, lumbar, and wings. Would have to make up mpunts as they are a very narrow seat.

Mike,

Do you presently have DR30 rear brakes?????

If yes! they are identical to Z31 300ZX rear rotors.

If you don't want to buy NEW, find ANY wrecker that has Z31's.

Are the rear z31 calipers similar to DR30?

Mike Cash - how did you go getting through regency?? or have you got any more info on what you would need to do?

ghostrider: im assuming that z31 rear dics would be the import old rb20 z31 or the aussie one, or are they the same size?

nah i got the dr30 rear end on mine at the moment and my dics are undersized from ever use.

as far as regency goes, aparently all you need is the same dics size as a car that had an rb20det. in my case i used r31gts fronts and dr30's rear and other cars have been passed without any engineering certificate or anything.

Will S13 seats fit - i got a set for free.

Measure the rail spacing. I measured a set up for my R31 (which may or may not be closer in design) and the S13 rails were about 45mm too far apart - the R31 centre to centre of the rails was 415mm where the S13 was about 460mm.

What or how do you call an DR30 HEAVY???? What are you comparing it to???? Maybe compared to a Mini, but to another Skyline, it's one of the lightest. DR's max weight 1250Kg, R31's OZZY sedans 1600Kg, HR31 coupes 1350Kg. How you say heavy????

WHOA! where'd you get that weight from for the aussie R31!?!?! I weighed mine with 40l of fuel, spare, tools, jack, assorted crap and full trim and it was 1280kg on an extremely accurate weighbridge. Mine is a "stripper" model GX though, with no luxo bar power steer and aircon, with basic trim, and its manual.

All reports I've heard peg the HR31 at closer to 1400kg, on the + side....Especially for the sloppy fat bitch Passage's...

      There's probably an underlying issue with the A/C system too. I recently fixed mine, now it's fully control by the Haltech and car's factory HVAC controller  Have a squiz here:

      And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.

      Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.

      I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications. This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.

      Deeve, I don't suppose that you've made any progress on this? My Stagea has the exact same problem, and just like you, I've read through as much as I can online, with no real progress. My car isn't throwing any codes at all, which is a little frustrating. I've changed plugs, checked the wiring and harness. A new MAF gets here next week, but I'm not hopeful it will solve the issue.
