MarkDerby Posted May 27, 2012 Author Share Posted May 27, 2012 been doing some cleaning and painting today .. De oiled/greased Painted all external items Black and Silver .. the Main Block is going Red to match the plenum Now i Read somewhere that its wise to Tig/weld the 2 nuts on the counter weight on the crank as these tend to come loose ... what u guys think ?

Hi Mark, A lot of stuff is belt n braces with these cars,unless your engine is cammed and will make crazy rev limits its pointless mate.

MarkDerby Posted May 27, 2012 Author Share Posted May 27, 2012 thanks for that ... i did wonder just thought i ask about it the way it was said on the page as if its quite common for them to come loose and all so some thing about drilling out the oil way hole that has the pushed in bearing tapping it out and using a Grub screw to block the hole instead Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 27, 2012 Author Share Posted May 27, 2012 (edited) all so i'm thinking some new injectors in there .... 750 or 850's ? Edited May 28, 2012 by MarkDerby Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 any thoughts to this will be looking to get around 600hp there about once i have finished Quote Link to comment Share on other sites More sharing options...

Gonzo12c Posted May 28, 2012 Share Posted May 28, 2012 maybe i missed it but i thought you was doing a cheap rebuild and using stock rods which you said were good for 500 now you wanna top the dyno leader board. You will need a considerable amount more done to the engine to achieve that a set of pistons and injectors isnt going to do that. Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 was .. but if u look on my last list got eagle rods down .. my total Parts bill is £1577 to door Total Engine Rebuild bill with Machining work and some used bits and new Injectors £2107.39 Quote Link to comment Share on other sites More sharing options...
Gonzo12c Posted May 28, 2012 Share Posted May 28, 2012 With the amount of time and money that Bob has put into his zed to achieve his dyno i think you are crazily optimistic if you think 600 is possible. Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 (edited) why ... if the engine is good for that power and more ... tubs are good for 700hp there about Mapping and injectors to flow the fuel why not ? May be a little optimistic but where would get/be if we wasnt i would like 600 (Crank) but lets see Edited May 28, 2012 by MarkDerby Quote Link to comment Share on other sites More sharing options...

Gonzo12c Posted May 28, 2012 Share Posted May 28, 2012 lol well i see so many claims of big power and things are good for this much and so on and so on However i know by simply looking at specs on other zeds that are running 600+ exactly how much work you do need. Simply building a engine and chucking it in isnt going to do it. You ask whether to use 750 or 850 injectors well things like air flow starts to come into the equation and then mapping and so on. Not just put 850 enterprise`s in and get an extra 50 brake. A bit of relaistic management and full car planning rather than just the engine is in order.

Eggs Posted May 28, 2012 Share Posted May 28, 2012 750cc injectors should be ample for 600bhp Mark,I think the cc rating is the the amount of fuel the injectors will flow for the same bhp give or take a bit. DeatschWerks injectors are frequently recommended as being reliable, closely matched and flow what the rate they should. You will have to look into whether those particular injectors require any modifications/adaptors to fit the fuel rail or whether you are better off getting a new fuel rail as well. What is the standard crank good for power/torque wise? Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 i do understand what your saying just trying to sort out what injectors will flow right for that type of Power i know sticking the big'st injectors in there isnt going to do the job right unless other items are sorted first and what i have been reading/told/advised its possible but even if its 550fwhp ... still bloody good and not to far off my target :) Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 Quote ... of web sites 700>800hp before looking at getting mods done to it .. aprently its a Forged crank anyways and the only thing that can be found as a problem is the center weight is bolted on ( coming loose ) Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 just had a little thought .... Exhaust Headers ..... are thay both the same design ? AMS Max Flow $495 http://www.z1motorsports.com/product_info.php?cPath=6_19&products_id=3696 Mike Smiths MSP $695 http://conceptzperformance.com/Cart/description.php?II=1443&Car_Type=300&UID=2012052811501980.1.103.33 Quote Link to comment Share on other sites More sharing options...

Paul C Posted May 28, 2012 Share Posted May 28, 2012 AMS pretty much ripped off the MS design - supposedly porting them further to give slightly more flow - but essentially they are the same! Quote Link to comment Share on other sites More sharing options...
Paul C Posted May 28, 2012 Share Posted May 28, 2012 if you believe it here are the flow results: http://www.300zxclub.com/store/popup_image.php?pID=2955&imageNum=2 Quote Link to comment Share on other sites More sharing options...
MarkDerby Posted May 28, 2012 Author Share Posted May 28, 2012 i did wonder but there is a Mega saving to be had .. the only problem is all my order is from conz as Z1 are crap on there prices way more on RRP ... and no discount what to ever ... just trying to work out the cost ratio item plus postage z1 ...... or cost as postage is all ready done just need to speak to conz see what price thay can do the headers for Quote Link to comment Share on other sites More sharing options...
Stephen Posted May 28, 2012 Share Posted May 28, 2012 thats a lovely chart but what does that actually mean in real life. Quote Link to comment Share on other sites More sharing options...
Paul C Posted May 28, 2012 Share Posted May 28, 2012 thats a lovely chart but what does that actually mean in real life. its the flow rate of each port on the manifolds. There are other factors but basically the higher the flow the more capacity to run more power as you are removing restictions on the gas flow in & out of the engine Quote Link to comment Share on other sites More sharing options...
Stephen Posted May 28, 2012 Share Posted May 28, 2012 Yeah I meant in terms of percentage gains. Quote Link to comment Share on other sites More sharing options...
