So tonight and over the weekend i did a bit of work on the MPV conversion.

First however, i did some work for BigPerm on his Cressida stuff:

Machining out tophats, oil seal rings into coilover sleeves, making little alu spacers and soon to machine his hubs down. Lots of fiddly things.

Inspired by that however i swiss cheesed the traction brackets:


So they are ready to weld on and then be trimmed to size.

And then setup the brake upgrade with the MPV discs:


Uses the stock RA28/40 brake caliper adaptor:


Which ill have to weld a 5mm plate to the inside of to drill and tap (along with a 3mm plate on the outside for extra tapping)


Coming together nicely, i would have welded it tonight, but i had shorts and a tshirt on and didnt want to make noise for the neighbours any more than i already had.

nice work I love big-worms wagon! 1J in disguise and particularly his meshies

[takai]

Yeah, its quite a nice wagon eh.

I got a little bit of work done on the spoonter tonight. Spent about 30mins welding before i ran out of gas



Welded on the traction brackets. Still need to be reinforced and then profiled nicely.

Also welded plates to the brake caliper mount, so i can drill and tap them. Ill be welding another pair of 5mm plates to this side that you can see here for extra tapping distance.

[Mr Awsome]

its looking sexy takai. how come your welding and tapping. not just welding some nuts on?

[MAGIC MAN]

dude i hope your not running welded brake caliper brackets, i've heard too many stories about these failing?

[takai]

One nice thing about having two cars to work on is that there is never a dull moment when you have nothing to do. So before setting about dismantling my 2JZ i welded up the caliper brackets, and after disassembly i drilled and tapped them. As such i now have a complete brake setup as so:


You can see here that it still uses the stock caliper bracket, with 5mm welded to the back side for spacing, and 3mm to the front for extra tapping depth:

Big thanks goes to Joel (TurboRA28) for his idea of using the stock bracket redrilled to suit.

And finally here it is all together with the RCA as i was still a little concerned that it might foul.


I also welded and gussetted the traction brackets, so they just need to be ground back and they are ready to go too.
Tonight or tomorrow will be on the lathe setting up a bunch of spacer rings for the brake conversions.

I think the pics explain it. I need 5mm of backspacing from the existing bracket to make it all line up. I could weld nuts on, but welding big chunks of steel to it make for a much stronger caliper adaptor.

Only when people cant weld properly. In this case the welded plates arnt taking any of the direct force of the braking, they are distributing it across the stock 5mm thick caliper adaptor plate.
