mjrstar Posted July 28, 2022 Share Posted July 28, 2022 Sweet as, do you need regulator & flow meter too? I have just rangi'd up a tacking band to suit 3" for you to use so that better be your exhaust tube size.. 5 Quote Link to comment Share on other sites More sharing options...

ajg193 Posted July 28, 2022 Share Posted July 28, 2022 Other idea is to use your high speed data log to look at crank sensor at a range of rpm at steady state. Will show you which cylinders are misbehaving Quote Link to comment Share on other sites More sharing options...

Big thanks to everyone who pitched in for buying another one, amazing. Cant wait to go pick it up, hopefully early next week! Also big thanks to @mjrstar for letting me use his Argon bottle so I could make a start on some welding. A few tacks seemed to go surprisingly well, so thought I'd give it a go welding around some pipe. I've got a lot to learn but I was pretty happy with this for first go. But man, it was real good fun. I will stick to the plan of tacking this together then getting some better help for welding it the rest of the way around. However I'm keen to learn how to improve. I was expecting much worse, starting with stainless which I understand is a bit harder than mild steel. I'll try get some hangers in place and the general layout sorted this weekend hopefully. 33 Quote Link to comment Share on other sites More sharing options...

Muncie Posted July 30, 2022 Share Posted July 30, 2022 That weld is all good for exhaust stuff, I've paid big money for far worse. Maybe jam that strain gauge I gave you on the block so you know when its going to explode again. 2 Quote Link to comment Share on other sites More sharing options...

It's a good 'reliable toyota corolla of the ac/dc world of welders'. You'll have fun. I see a whole new level of Dave projects and associated graphs now. Just remember fotr neat welds - cleanliness is next to godlyness (if there was a god) but what ever you do don't ever use brake cleaner to clean anything you are going to weld!!! Creates very very dangerous fumes! 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Roman Posted July 30, 2022 Author Popular Post Share Posted July 30, 2022 Yes I havent forgotten about strain gauge @Muncie... thanks for that. Just still trying to find a good application for it. I have indeed just send't'd it, and I've got one or two bits left until it'll be out the back of the car. Then decide where to put a flange and chop it. Hopefully tomorrow I'll get some hangers fitted, and then it's nearly it done. Will try make them a bit adjustable somehow, so I can fiddle with the height if it bangs on stuff. I currently have it jacked it up to max height so that the muffler and everything else hits the body, or very close to. Then following the contours as closely as I can. I've had varying amounts of success with the welding. Welding the pipe onto the back of the muffler was hard because the pipe was a little bent and so there was an air gap. So the upper part just wanted to melt away without reaching the second piece too well. But figured it out. There were a few other areas where I realized a little too late that I need to resharpen the tungsten, or some other similar thing. But thats alright. Learning something from each mistake. Man I am looking forward to getting this going again with 1NZ! 32 Quote Link to comment Share on other sites More sharing options...
Roman Posted July 30, 2022 Author Share Posted July 30, 2022 Does anyone have any good advice on how to do exhaust hangers? It seems like a fairly simple task, but I can also see that if I hang the weight incorrectly it could put strain on the extractors, or bang around a lot if the exhaust moves heaps. Is it a good idea to have the rubbers hang at 45 degrees rather than vertically, so it constrains movement both ways? I'm not sure if it's worse to have too few or too many, and what best orientation etc is. Better like this or like this? Quote Link to comment Share on other sites More sharing options...
Yowzer Posted July 30, 2022 Share Posted July 30, 2022 On my last exhaust I looped the hanger around under the pipe, as I found having it welded to the sides it would eventually fatigue and rip a hole in it. As for hanging methods, I just replicated the factory method. Seemed to have held up well enough despite smashing it constantly into the road. I was gonna say attach the runners to the gearbox, but derped and remembered your engine is facing the wrong way. 1 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted July 30, 2022 Author Share Posted July 30, 2022 Loop under the pipe sounds like a good idea, thanks. Quote Link to comment Share on other sites More sharing options...
sheepers Posted July 30, 2022 Share Posted July 30, 2022 Tbh my man the amount of time you'll run this exhaust before you change it will be pretty short in the grand scheme of things. I would suggest that the hangers are Perry irrelevant to a greater extent. Make it look OK without trying to re invent the wheel and you'll be golden 1 1 Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted July 30, 2022 Share Posted July 30, 2022 While simpler is definitely quicker, I quite like these Jag XJ40 exhaust mounts that locate things in a triangle. I did make sure there was a flexi upstream of them so the engine could move around without twisting the exhaust though. 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted July 30, 2022 Share Posted July 30, 2022 Great progress! This may not be all that relevant, but I have found on my Honda due to the way its used, there is far more side loading on the exhaust from cornering forces than vertical load from its own weight. This is something that wouldn't be a problem for a road car, but for a track machine you don't want to underestimate how much side to side loading will be applied. / like sheepers says get version 1 up and running with whatever stock body mounts you have then fine tune it down the track. 1 Quote Link to comment Share on other sites More sharing options...

Roman Posted July 31, 2022 Author Share Posted July 31, 2022 Just going to put it in. Because the rods dont work with factory pistons which have press fit pins. They have larger clearance to suit aftermarket pistons with floating pin and circlips. If the piston broke first then theres nothing to be gained with just rods. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Roman Posted August 2, 2022 Author Popular Post Share Posted August 2, 2022 Picked new motor up! At risk of sounding like a broken record, thanks heaps to everyone that has helped. I am amazed and very grateful. So I stripped off all of the hybrid junk, and either way the head needed to come off. As I will either swap the other head onto it, or need to swap the valve springs and cams over. Then proceeded to get the 1300 motor out of there. I need to steal its sump to swap onto this motor. As I've done all these jobs previously it has been fairly smooth sailing this time around! 37 3 Quote Link to comment Share on other sites More sharing options...
