Hi Guys,

Thought some people might be interested in what I have been working on. Its a RB30 with a custom sump adapter I designed that moves the diff section of the sump forward 140mm. I then cut the sump up and got a heap of water cut ally sheet and got it welded. I haven't done the windage trays yet and also it needs another oil drain point int he front of the sump. Sorry about the pics it was just taken on my iphone. This is a sump I want to put into my datsun 1200. There was 10 hours of welding in the thing!

awesome. can't believe I didn't see this before. it's something many people have thought of. wanting to relocate RB26 engines but being hampered by the fact that the diff and front drive shafts are in the sump and so if you moved the engine you'd end up with either some crazy driveshaft angles at best and an undriveable car at worst. very nice solution indeed. :)

excellent work. I'd love to hear how it's going these days?

Don't really know much about this stuff but sounds awesome!

Is this something you would need to successfully install awd into say an R31 or S13 for example.

Any news on the build or any other builds of this nature?

Hi guys, I didn't have email notifications set up so I only seen this while browsing, I have not really progressed this car much as I have about 50 other projects on the go, Trying to really finish them and get stuck into this thing. I have designed a new way of building the sump with a lot less welding, and would just be generally better in design.

I would be happy to make one of these for someone or supply a modified sump adapter if you would like to buy one. I bought 4 more 26 sumps just to have a play around with along with a 250 amp kemppi tig.

Currently working fly in fly out so it has sort of screwed me of time...

Also I would be able to move the sump forward 170mm but that is the limit, above that I think you would be better of ditching the diff all together and running a "normal" lsd in front of the motor.

      This sounds like someone who would have owned an R33 in their past... It's okay, I'm 100% picking up what you're putting down Mark.

      Jacks that fit under GTR lips that can reach the subframe?

      By MBS206 · Posted

      Just back on what was raised about jacking off the the tow/tie down point on the front of cars. I've used it plenty. I've also watched it on a car where you could see it move the front end of the car. It was like the front end/whole car being tweaked and twisted a bit. I will say, I struggle to find good jacking points on MOST cars. The ones that have good points, I then normally struggle to find a jack tall enough to make the car change height!   One of my go to points for either the jack, or the axel stands though, is either a suspension pickup point, OR a subframe to chassis major bolting point. I actually think its the subframe on my R33 that has a bit of a bend in it, from being jacked in the middle too. However, it could have been one of my many other cars I've had over the years! Or it could also be the from me jacking it up, and the fact the top of the front radiator support isn't there, so it can allow the front of the car to move and bend etc.

      My apologies. I forgot we were talking about weird beard M series stuff. Had been talking elsewhere with someone about an R33 with similar subject and got confused.

      Nope, I don't like the look of ND RF, or any ND really, I don't like their faces or arses, why, because of their "modern" lines, the NC, whilst "modernish" has a more rounded shape that I like Well, that's how my overly judgemental eyes see it anyway

      Should be more than fine, especially the overall fuel pressure would never exceed 3.5bar (assuming that thing never gets more than 0.5bar of boost in stock form). According to the chart, it's 11amps.
