Seedy Al Posted April 15, 2014 Share Posted April 15, 2014 Whats this? I have a small project running round in my head. And it requires me to some how adapt an auto onto an engine that I dont have a trans for. So was thinking about making an adapter that bolts to the engine and theb the trans bell housing onto that. Anyone tried this before? Looking for some first hand experience. Tips. Tricks etc. I have a decent idea of how im going to do it....

UTERUS Posted April 15, 2014 Share Posted April 15, 2014 Does no trans exist for this mystery engine? Quote Link to comment Share on other sites More sharing options...
durty Posted April 15, 2014 Share Posted April 15, 2014 Pretty sure Yoeddy made an adapter for the V6 engine, check his thread? Quote Link to comment Share on other sites More sharing options...
Spencer Posted April 15, 2014 Share Posted April 15, 2014 Its straight forward al. You have to make sure you get the centres bang on but you can get them to chuck glides/T400's on all sorts of shit. You just have to space out the torque converter to suit. Quote Link to comment Share on other sites More sharing options...
Spencer Posted April 15, 2014 Share Posted April 15, 2014 Ive seen dudes ghetto up templates using Perspex then cutting them in steel. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted April 15, 2014 Share Posted April 15, 2014 I would make it in wood first then get someone to laser cut/CNC it in alloy. The trick would be making it thick enough to fit bolts and threads both ways yet not so thick that it moves the release bearing/torque converter away from the clutch/flexplate. Didn't MJR make something like this for his EVO powered MX5. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted April 15, 2014 Share Posted April 15, 2014 I'm not sure any bolt on template would be truely accurate enough to gurantee alignment, it wouldn't need to be far out to damage gearbox bearings... (could be wring though) Use the template to get the external and internal profile correct leave the centre in your final laser cut flange (like the cardboard cut-out) then survey and drill /tap the mounting positions ... Jig below is to centralise the input shaft so it's not loaded in any direction . Cardboard template next to the almost finished 10mm steel plate. (cut out the cross brace by this stage) Quote Link to comment Share on other sites More sharing options...
Spencer Posted April 15, 2014 Share Posted April 15, 2014 You have to move the converter away unless you make it like 0.5mm thick? any movement away from the box means you engage the pump less/not at all. People run these all the time so they can use Chevy pattern boxes on BOP shit. They come with spacers for the Torque Converter which are equal size to whatever plate you use. They are normally 1/8"thick steel Quote Link to comment Share on other sites More sharing options...
KKtrips Posted April 15, 2014 Share Posted April 15, 2014 Did you space your flywheel back 10mm too? Edit - damn Spence keeps snaking me. LOL Quote Link to comment Share on other sites More sharing options...

(could be wring though) Pretty sure you have a tiny bit leeway on the centre, there are tonnes of bolt on adapters in the market. Most will use existing dowels to locate it correctly.

mjrstar Posted April 15, 2014 Share Posted April 15, 2014 Yeah spence it's probably going to be fine if it's within .2mm of centre, but this is not that easy to measure hence the centralisation of the input shaft and close tolerance locating hole which gets cut off later.. heh, no need too space the flywheel back.. Flywheel is from a nissan GTR (Same PCD as the mitsi crank but don't tell anyone) and now has no ring gear on it, the starter engagement is courtesy of a toyota corolla flexi plate. / enough of this spam 4 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 16, 2014 Share Posted April 16, 2014 I watched one made before I did my trade-my mind exploded with how awesome it was. Mr VVega was the culprit. take two bellhousings. One for motor and one for Trans. give to a machinist and have them chopped in a lathe to the correct lengths and with locating spigots to keep them aligned. weld the two halfs together. boom. Only works if the bellhousings have areas of the correct diameters to allow mating surfaces to spigot together. Easy if you have a lathe Quote Link to comment Share on other sites More sharing options...
Spencer Posted April 16, 2014 Share Posted April 16, 2014 Lol I remember that, for his Hilux? the fucking welding between those bits was crack up. Quote Link to comment Share on other sites More sharing options...

Seedy Al Posted April 16, 2014 Author Share Posted April 16, 2014 Lets just say the motor is hard enough to get parts for, so I don't even have a proper bell housing to start with. Only one hacked up manual conversation that uses ans adapter plate and cut up bell housing. Have considered trying to find an auto that suited the same bell housing so I could use the same adapter plate. But fuck knows what its off....

Spencer Posted April 16, 2014 Share Posted April 16, 2014 It was a 1UZ, oh yea forgot about that POS, that stuff went into the hilux. Yea welding cast alloy aint no thing. Quote Link to comment Share on other sites More sharing options...
Rookie Posted April 16, 2014 Share Posted April 16, 2014 I have talked to a friend of mine in some depth about this, all he did was spin up an extended bronze bush for the crank spigot, and bolted a bit of 12mm steel plate onto the block, which he had vertically in an engine stand, then then plonked the gearbox onto it and marked the holes, drilled and tapped and away he went. I think it has been in his car for 10 years now and he hasn't had any trouble. This was to put a w50 behind a turbo 4age. Quote Link to comment Share on other sites More sharing options...
