Aaron Neubauer Posted June 14, 2009 Posted June 14, 2009 Looks good! Any particular runner length your aiming for? Quote
waxhead Posted June 14, 2009 Author Posted June 14, 2009 Thank you. And the answer to your question 24 inches it the length i am looking for. If i can get it but thats the general figure Quote
waxhead Posted June 15, 2009 Author Posted June 15, 2009 Ok progress pics I have done the front pipes and hopefully will get the rest done tomorrow or at least this week. Then its time to remove them and weld them all solid and put them back on. Im reasonablly happy with how its turning out its no monzter style thing but its even length and held close to engine and out of the way. Quote
garvice Posted June 15, 2009 Posted June 15, 2009 Impressive. The turbo looks off centre a bit. Are you still going to be able to get the same length pipes for the back three cylinders? Quote
waxhead Posted June 15, 2009 Author Posted June 15, 2009 Yes the turbo sits further back , its done that way to try and clear the engine mount. The rear pipes will look different from the front. However they will be the same length , just some of the bends may be tighter Quote
garvice Posted June 15, 2009 Posted June 15, 2009 Sounds good, keep up the good work on government time. Quote
waxhead Posted June 15, 2009 Author Posted June 15, 2009 Sounds good, keep up the good work on government time. Thats nasty, Actually its good for the students as they get to see some relevance in what they are learning , a decent use for it Quote
garvice Posted June 15, 2009 Posted June 15, 2009 Win, win situation then. You are obviously a very good talker (or passionate about teaching) to be able to talk the principle into this situation. Well done. Quote
waxhead Posted June 15, 2009 Author Posted June 15, 2009 Well our metal work department went from the smallest department in the school to the largest in the last few years. So he is happy its all about funding . Every year i build something strange and ride around the school on it . The z car maybe a bit big to get down the footpath however Quote
xa1973 Posted June 15, 2009 Posted June 15, 2009 Looking good Mate, time well spent........ With all that extra weight on one side, will this affect your engine mounts? Have you given any thought since youve Turbo'd, those pipes will get mighty HOT and stay hot for a long time and transfer a lot of heat to your newly designed manifold Quote
waxhead Posted June 15, 2009 Author Posted June 15, 2009 It doesnt weigh as much as it looks. I will weigh it when i am finshed, the issue i think with the mounts will be the twisting it gets from the extra torque the motor develops Quote
sexual_sushi Posted June 15, 2009 Posted June 15, 2009 Yeah looking very good. You are getting a lot of work done. It's good to see some solid updates on a project. A man arts teacher at my high school worked on a 240z as a 'class project' as well. Unfortunately this was a few years after I graduated. Quote
RB30X Posted June 15, 2009 Posted June 15, 2009 I'm sure when you're finished it still won't weigh as much as an na manifold, those suckers are heavy. Quote
waxhead Posted June 16, 2009 Author Posted June 16, 2009 OK well did some more work on it today. of course i didnt have enough bends i was one short I will go get some more tomorrow and do some work on it thursday The intake manifold is just sitting on there at the moment so dont think its going to be running and touching the header at the same time I have redone number 6 as i was not happy with the angles in it ,you can see the redone one in the first pic After its welded and ground up i will hit it with the emery tape and smooth it all out before welding together Quote
nuclear_z Posted June 16, 2009 Posted June 16, 2009 Please tell me your going to remove the linkage shaft and run a cable... Quote
waxhead Posted June 16, 2009 Author Posted June 16, 2009 Im not sure yet i like the old school linkage.Im also looking at drive by wire so i dont have a cable at all Quote
xa1973 Posted June 16, 2009 Posted June 16, 2009 Im also looking at drive by wire so i dont have a cable at all Exotic.... Quote
waxhead Posted June 16, 2009 Author Posted June 16, 2009 Yeah im looking to get an ecu that has wheel sensors as well so i can have switchable traction control if i decide to do some track work. If you have drive by wire with wheel sensors you get cruise control as well. Also you get torque control off the throttle as well , so if you put your foot halfway down you actually get half power not half throttle , makes for a smooth powerband Quote
RB30X Posted June 17, 2009 Posted June 17, 2009 I hope with all the effort you're putting in you arn't going to use that awfully restrcitive dump pipe flange. External or internal wastegate?? Quote
waxhead Posted June 17, 2009 Author Posted June 17, 2009 Nah thats not the turbo i am running its just a turbo to help me sizing it all up I will be running an external to get the correct boost control i am after Quote
waxhead Posted June 17, 2009 Author Posted June 17, 2009 Ok well its finished pretty much Just have to weld it all solid now please excuse the mess in my car this is all pre my doing Quote
stevo_gj Posted June 17, 2009 Posted June 17, 2009 Looks great and there is loads of room there, well done! Now that the semester is over will you be using the school workshop to finish the job? Quote
waxhead Posted June 17, 2009 Author Posted June 17, 2009 I still have a week to go. But yes i will be spending alot of time in the workshop over my holidays Quote
Scoota G Posted June 17, 2009 Posted June 17, 2009 Ok well its finished pretty much Just have to weld it all solid now please excuse the mess in my car this is all pre my doing Have you figured out a sequence to weld them up to minimize distortion, or does the thickness and bends cancel that out? Quote
Thomo260 Posted June 18, 2009 Posted June 18, 2009 Where abouts are you mounting the external wastgate? Looking good by the way. Quote
