  1. Through experiance Ive found if you hand tighten or more the studs into the block you will end up with small hair line cracks between the bolt hold and water jacket in almost every instance. (not instantly but over time)

    I do them up till they nip up then loosen them off half a turn, with loctite the stud will stay in that position while you do the nut up. Leave the loctite 24 hours to do its job before doing the nuts up.

    As rule I do this with every stud be it a main stud or head stud etc.

    Also be sure to use the paste under the washers and under the nuts to ensure even tightening.

    Leave the gasket as it is supplied.

    In saying that about the studs in your application you may be fine hand tightening them but my oppinion remains the same about backing them off half a turn.

    I was told this is a massive no no because you then have loctite between the threads rather then the stud onto the steel of the block when it is tight, Then when you do it up you can squash the loctite.

  2. 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!

  3. Hi guys, got a sump adapter for sale. I had a project where i was moving a gtr sump forward 140mm on a rb30 and also am putting a 30 in my street GTR so I had a block put on the CMM machine. I designed up the adapter and ran an extra adapter off on the CNC while I was at it.

    Comes with all high tensile cap head bolts, washers and spring washers.

    Adapter of course - CNC machined and slash ground for a perfectly flat finish.

    Laser cut profile guides for notching the block.

    $430, Will ship aus wide! Located in SA, contact me on 0403431194, SMS preferred during the day as I work.

  4. First thing I would do is measure where the sump bolts to on a ls2 in relation the the height of the crank and compare it to a GTR. I have made a custom sump and adapter that moves the GTR diff forward 140mm, so I can mount the 26/30 further rearward. I already have a SR20 to RB25/26 box conversion jig and was even playing witht he idea of making a 4wd north south sr20 "gtr" (but put it in a clubman style thing)

  5. Thread revival!

    Where in the bearing tunnel is the best spot to measure for clearance?

    Should the caps be torqued up with out the crank inplace or...?

    put in your bearings, then mains caps, girdle and bolts that you will use (torques down). measure each main tunnel. U can measure at different spots on each tunnel. at say 12 and 6, 2 and 8, 4 and 10 o'clock etc.then measure up each journal of the crank. If the clearances are too big then you can get the caps machined down and the block line bored again to a size that is more appropriate.

  7. actually, they both run an r200 diff so both able as each other to handle the same power. the gtr one does have a factory mechanical 2 way centre while s13 is viscous LSD.

    gtr driveshafts are stronger

    gtr hubs are alloy

    they have the same geometery including the poor front mounting point for LCA (fixed in R33/S14 onwards)

    Can you elaborate a bit? If this is the case i will go pick up a later model subframe and transfer over my gtr gear! (is this possible?)
