Hi D, Wow, thats a fairly strong worded post that you have put up and indeed food for thought. Couple of questions though- are you saying that the old Ottoman empire controlled Palestine back then? I had no idea that was so. It was always my understanding that the whole campaign was about seizing control of the Dardanelles and thus ( I guess ) controlling the flow of oil to feed the German war machine. Are you also saying that WW1 was effectively started by an Zoinist elite? And 'contractors' - are you referring the the Australian army or self employed ex army involved in 'security'? Dave

A friend of mine is pretty turbo savvy. He has played around with a lot of them on 4wds. He is convinced that this turbo is too way too big and a waste of time. He thinks I'd be better off using something off say a Charade turbo or TX3 laser. He simply said a old 1.4 wont have enough exhaust gas to drive a turbo off a modern 2L. Logical argument...
I've been thinking about how to reply to this all day. Without wishing to insult your friend even considering a turbo off a Charade shows to me that he really doesn't quite grasp just how much air/ fuel these little motors actually flow. As I said before I actually ended up using the biggest T2 available off an 1800SSS Bluebird and that was still too small. That started spooling seriously at about 2800 and would rev through to 7500 no problems. Considering the Japs are renowned for putting too smaller turbos on cars I honestly think that you should have a leap of faith and just try what you've got. Remember too that your application is vastly different from some-one with a 4wd, so what if it boosts a little late. The thrust back in the seat as you watch the speedo climb and grab gears some would say is better than sex and you'll more than pick it up in the top end! Interesting what Sikyne is saying about the exhaust manifold. My experience using a 'J' has been really good but if anyone would know Simon is the man. 8lbs boost, sensible spark and correctly fueled and you will have a great little powerplant. Go make it happen and remember plenty of pics so we can follow your journey.
Cheers Dave

Re the exhaust housing flange while I would be the first to put my hand up and say that I'm not up to speed with the current crop of turbos used these days from memory the T2's were all interchangeable on that exhaust flange ( and we did plenty of changes )so I don't see why the T25 should be too much different. Perhaps one of the other guys could confirm this. Re the inlet manifold, have a look at what Sikyne has done with his build. I would be tempted to head down that path rather than using a stock manifold as you will achieve a much better fuel+ air distribution and they are not too difficult to make. Just a bit more tubing required. All that I can say is that this is what I used both super charged and turbo'd and it worked really well. Cheers Dave

You may be pleasantly surprised. Just use it and see how it goes.Also the SU will be very forgiving due to the variable choke size which will help get the airspeed up no end. FYI when I first built my turbo setup years ago we used a T2 off a 1.5 Pulsar and it more or less boosted straight off idle and stopped making usable power at 3500!! We ended up going bigger and bigger and ended up with the biggest T2 available at the time off an 1800SSS Bluebird and looking back that was still on the small side ( but still went really well )

Anyone had any experience using stock manifold with J pipe vs custom exhaust manifold? Im assuming the custom would be better, but how much?
I have and it worked a treat.Strong and reliable made from plumbers steam pipe bends. I used a T2 ( the biggest available ) with a very basic early fuel only Link computer and it was a little weapon yet totally streetable. Using an SU as a draw through is real easy and I know that this may sound a bit rough but as I have already explained to one of the NZ Datsun guys with exactly this setup when it comes to tuning having the ability to actually drop the main jet when the choke is pulled out thus richening the carb big time will give you a very good idea of where you stand with the mixture.

You can do this very easily by simply fabricating a 'J' off your standard exhaust manifold using plumbers steam pipe steel bends, and drawing through a 1"3/4 SU carb.Forget about intercooling at this stage and at 8lbs boost with conservative spark ( max. 30 degrees total advance ) you will have a very lively, reliable street powerplant.Big things are not to overboost, overspark or underfuel. A T25 or similar would be ideal as long as it can handel a draw through. A nice, free flowing 2 1/2" or bigger exhaust tail pipe is also required. The easiest and probably the most efficient inlet manifold is to get some to fabricate up a log type out of exhaust U bends meeting up to a top tube that is fed from the middle ( hope this makes sense ) A 1"3/4 SU is capable of flowing 300hp worth of air and fuel and very easily tuned so are an ideal ( if not slightly old fashioned ) way to go. As far as engine mods go really at that boost do nothing other than make sure that the head gasket as well as the block and head surfaces are good, and of course the valves are all lapped in nicely as well as some good valve springs. A oil feed to the turbo from the oil pump ( for Gods sake make sure that its FILTERED oil and of course a drain to the block. Simple, easy and very effective. Performance- done nicely it should be good for low 14's through a quarter mile. Cheers Dave

Sorry forgot to ask in the last post would you guys by any chance know anyone in the local MTB club who would be running the event that we could get in touch with? There seems to be minimal information coming out about the event and I am really keen to get Brad over there early to ride the course and get used to the time zone difference. Cheers Dave

Thanks for your help guys.Bit of a pain for him at the moment as he's only 20 and too young to hire a rental. Hopefully should be able to tee him up with someone else heading over but the NZ contingent is totally disorganised and its very much every man for himself with absolutely zero assistance from Bike NZ.He races in XC. Cheers Dave

Guys, My son ( and maybe myself ) is looking at coming over to Tassie to race in the Oceanania Mountain Bike Champs that are being held in Glenorchy, Hobart from Wednesday 27 March through to 1 April. Can anyone help with some accomodation recommendations and cheap rentals? ( or does he need one with the distances involved ) Cheers Dave

Hi, I sent you a pm some time ago re the Mad dat steering box brace for the 1200, not sure what happened there. It looks as if it may well have gone to another member but if not please pm me. Cheers Dave
