  1. Thanks for all the responses. It seems pretty clear from the replies, and from other web research, that toughened/tempered glass cannot be cut to the degree I require. The good news for me is that acrylic and polycarbonate windows (not windscreens) can be used in pre-1994 vehicles in this country.

     

    Now that is something i am shocked but pleased to hear... leaves so many options available.

  2. i remember seeing on a hot rod show from the US - will try to remember which one - where a window was cut down by scoring the glass, then covering the score with alcohol then lighting it, then section was then wiggled up and down until it parted from the main area of the glass..

     

    cant tell what type of glass it was just thought it might jog someone memory

  3. those are some very good points he brings up there.

     

    though i have never seen the examples he gives being attributed to the PITH syndrome. Most people here that give examples is relational to high rpm blow by (not attributed to a loose engine) and visual inspection of the the cam areas to specifically show too much oil there.

     

    anyway, im hopefully be building a sump of my own soon for an RB30/25 conversion and this has some very good info on the baffle designs.

  4. Sounds fair, and i should have noticed the change in pickup point on the sump.

     

    i've looked at a few, alot use a steel bar through a bracket on the wall and each trap door, and not actually a hinge.

     

    wouldnt need to be alloy as it wont rust in there, but why not while your at it.

     

    im thinking that the diamond shape baffle would still need holes under it to allow oil to level on cruise, and just using the trap doors to force fill the baffle on corners.

     

    question though, how much space should you leave between the diamond baffle and the front and rear walls of the sump pan? should this be sealed to force the oil into the pickup area, rather than allowing it to go around it?

     

    My sump is far from the stock sump - its 100% custom at this point. If your not familiar with putting the RB's into the Z's, you must convert it to a rear sump - it won't clear the crossmember. So my choice is limited to a completely custom pan or utilizing the RB20 rear sump pan - which has some severe limitations for my intended use.

    I have checked out the RB26 updated baffles/sumps and they won't really work as they are built if utilized in my setup, but I have considered their ideas.

    There have been some excellent discussions here and on the RB mailing list,(for those putting RB's into Z cars) about the oil in the head and its not quite as it seems.

    An engine builder who has built many very high hp RB26's,(up and over 1000hp), had some excellent input. Bottom line, his analysis showed me that what we have often attributed to the "pooling in the head syndrome", just doesn't fit that issue.

    I can elaborate, but the data makes good sense and I will NOT be including a head drain in my setup, (but I did expand out the returns).

  5. Bob H - is this oil pan been modified the be shallower than the std Sump? Obviously with the removal of the front Diff assembly some fabrication was required, just curous as to the thought process involved in the further change of the front sump pan. was it required for cross member clearance?

     

     

     

    Tomei Japan has off the shelf baffles - http://www.nengun.com/tomei/oil-baffle-plate

     

    also Trust has too - http://www.nengun.com/trust-greddy/oil-pan-upgrade-kit

     

    - just a little off topic - there is alot of talk here in AUS in regards to excess oil in the heads of the RB26's, which lead to the use of restrictors in the oil feeds to the head, also if a track car then an additional oil drain from the rear welsh plug in the head.

     

    Here seems to be a good site for ideas, turns out the Tomei baffles use the M3's rubber baffles

  6.  

    wouldn't there be people on ebay selling complete single-moulded peices for r33's that are a copy of the evo ones?

     

    there would be no way to use something like this unless using tape all the way accross the unit .. as there are no gutters in teh roof on skylines to attach them to.

  7. Pay more attention to the collector arrangement to ensure a smooth transition from the runners to the turbo flange, than the exact length of the runners ..

     

    you will also need to work out your runner length and thickness of material that is required for your application .. thicker wall/smaller tube will aid in spool time, but restrict flow up top .. reverse for bigger runner ID

  8. Gday,

     

    I have been thinking about changing my exhaust system on my skyline. The current system is a 3 inch dump pipe of a HKS 3040 going down to Cat convertor (now believed melted) through straight pipe to a X-Force 3" inlet and twin 2.5" outlets.

     

    I have decided for extra flow and reduced noise to go to a 4" off the turbo to a 4" inlet Cat convertor then split the 4" outlet into twin 3" exhaust pipes back to a pair of rear mufflers.

     

     

    Now i'd like to make this up myself if possible so i am after ideas and pictures of a collecter design that will merge the 3 pipes together smoothly for flow.

     

     

    any help would be great.

  9. i've just got a Lathe myself (borrowed from a mate who is moving for a few months) and i was trying to find some info on how to centre the 3 jaw chuck a little better as it seems to not be centering very well.

     

    i've read through the links posted and dont think the mods in

    http://warhammer.mcc.virginia.edu/ty/7x10/vault/Lathes/7x10-7x12-Projects/SetTruBackplate/

    are really something i wanna do with a borrowed Lathe

     

     

    any tips would be great
