Swampy442 Posted December 9, 2010 Share Posted December 9, 2010 (edited) Fabricate a new one maybe thats the diference between a big case 6 speed diff and small case 5 speed diff? Edited December 9, 2010 by Swampy442 (see edit history) Link to comment Share on other sites More sharing options...
David Reid Posted December 10, 2010 Share Posted December 10, 2010 Prop lengthening is only approx £75 give Dave Mac propos in Coventry a call Link to comment Share on other sites More sharing options...

hodge Posted December 10, 2010 Share Posted December 10, 2010 Nice bit of machining that mate. Link to comment Share on other sites More sharing options...
Swampy442 Posted December 10, 2010 Share Posted December 10, 2010 Very nice indeed Doesnt answer the question though... Link to comment Share on other sites More sharing options...
dcarrter21 Posted December 10, 2010 Author Share Posted December 10, 2010 The gap between the drive shaft flange and the diff is too much, pulled the prop out abit to extend it on the spline, no gap! But the bolts wont line up in the centre bearing bit of the prop. So.... Ive made the doughnut thicker the line the holes back up! Ill post pictures of it fitted tomorrow!

pedrosixfour Posted December 10, 2010 Share Posted December 10, 2010 Is it just me being stoopid or is that a very big fackin lump of metal to have spinning at such speeds as the prop shaft does? Link to comment Share on other sites More sharing options...
dcarrter21 Posted December 10, 2010 Author Share Posted December 10, 2010 Its highly balanced! Link to comment Share on other sites More sharing options...
dude Posted December 10, 2010 Share Posted December 10, 2010 The problem is the prop is for a big diff and you have a small diff. The rubber donut is very dense and pretty heavy, you could lose a bit of weight from the new alloy one or just use the rear prop off a j spec auto.

pedrosixfour Posted December 10, 2010 Share Posted December 10, 2010 Its highly balanced! Its probably fine mate, I'm not doubting your skills in the least. And again, commendable work. Its possible that the pictures are throwing my judgement way out as it looks massive. But I do know the size of the normal coupler and I'll assume its not much bigger than that anyway.

Chris Wilson Posted December 13, 2010 Share Posted December 13, 2010 You may well find zinging and other resonances in the drive train without the rubber doughnut, and more shock loadings to diff and gearbox. The doughnut replacement sure loks pretty hough, your machining skills are getting right up my nose these last few days.... Link to comment Share on other sites More sharing options...
dcarrter21 Posted December 13, 2010 Author Share Posted December 13, 2010 Ive got a spare head at work that im going to have a play with. Should be intresting!! Link to comment Share on other sites More sharing options...
pedrosixfour Posted December 14, 2010 Share Posted December 14, 2010 Ive got a spare head at work that im going to have a play with. Should be intresting!! From recent evidence there isn't much wrong with the one you have on your shoulders right now. I'd do ALOT of reading before you attempt to better Toyota's take on a well designed head though. I don't think There is much room for improvement on modern multi-valve cylinder head design without having an intimate knowledge of all things related to it.

dcarrter21 Posted December 14, 2010 Author Share Posted December 14, 2010 So maybe a new billet head? Link to comment Share on other sites More sharing options...
Swampy442 Posted December 14, 2010 Share Posted December 14, 2010 Id look at a 1JZ head and compare it to the 2JZ, 1.5JZ conversions used to be all the rage Link to comment Share on other sites More sharing options...
