Is it any different to what I've done?
I don't know how similar the AE86 and the MA61 are when it comes to struts/hubs.

I believe that R33 GTS front brakes are the same as R32 GTR front brakes, and if this is the case then my car has these, and so does Gabe's - his car is well documented on this forum, so do a search here, or look for his car in the Member's Rides.
I didn't do my conversion so I'm a bit hazy about exactly what was done. However, I have standard struts, and the hubs still have standard 4 stud pattern - AFAIK, a new bracket has been welded to the strut to mount the caliper, and also the disk hat (I think) has been re-drilled to match the 4 stud pattern.
I can take pics on the weekend if you guys want...
By the way, you need to run 15" wheels to clear the calipers, and even then be careful about wheel choice, as not all will clear.

Option up, what size discs are you running and what wheels?
Very interested,

I'm using R33 GTS25t (297mm) on my KE70, and I've written stuff about it before. I'm also using 15x7 Falcon rims, couldn't get them closer to the brakes if you tried

I second that you have to be very selective on the rims , some nissan rims fit over the brakes with the 297mm discs . Another convo is the z32 280mm discs so there's no clearance issues . I have three sets of 15" rims which are from 38 > 40 offset and they don't clear caliper which out spacers on nissan struts .
But there also seems to be differences in the z32 alloy to r32gts steel & alloy calipers so you really need to measure the caliper up you are going to use first .

I'm using std struts with r33 GTS (non turbo 4 stud discs) over the trimmed down (diamiter) hubs with new calliper mounts and r33gtst calipers. Cost is about $300 so far (had a mate make up the cal mounts). I'v trial fitted it all so far and it all fits perfect under 15's. Just waiting for my other hub to be trimmed hint hint mrshin.
I'm a pleb when it comes to cars but i'm fucked if i'm going to pay someone else serious cash to do something that turned out to be bloody simple to do.

Can we get some pics of that mate.
Any other pics from you other guys would be great too.
I'm just considering this conversion over a stock 180sx setup.
Would the 180sx setup be allright?

incidentally, R32 GTR discs are not the same as R33 gts-t.. the R32 GTR ones are phat brembos, the R33 ones are the same caliper as the R32 gts-t (apart from a longer mounting thingie), and a slightly larger disc

nah greg, only specific R32 gtr's have brembo callipers. I think it is 1993+ models, where they begun using the 324mm rotor.
before that was a 296x32 with Nissan (sumitomo?) callipers..
i found this out when i was trying to source the 324mm setup for my ma61

As promised, some pics:
Right front wheel. Inside clearance from the caliper is more like 10 - 12mm.
Wheel off: caliper sits nice and close to the edge. Also, see the four bolt ends in between the wheel stubs - these attach the disc onto the AE86 hub from behind. Been meaning to grind off the Nissan wording, but never got around to it...
From behind; see the new bracket made up to fit and position the caliper...
Closer view from behind - you can clearly see the welding of the bracket onto the old caliper mount
From above. You can see the holes for the 5 stud pattern in the disc, and how this is bolted onto the AE86 hub.
Got this done around April 2001, and it's been working well ever since. Got the master cylinder bored out soon after, but to be honest it didn't reduce pedal effort or increase feel noticeably. Soon I'm going to get the master cylinder and proprtioning valve overhauled - I've been told that pads are wearing unevenly left to right on the front.

They look great. And it looks like an easy conversion
So they are GTR r32 calipers which are the same as r33 gts-t calipers..
Cheers

One word of warning for the configuration shown above, welding of any braking components is not legal in NSW and will not pass engineering.
Just a heads up, engineers like to see a nice machined caliper bracket, the nicer the workmanship the easier it is to get passed.

Those calipers look suspiciously like 300 zx/180 sx non alloy jobs to me.... My cal mounts are 2 peice bolt together jobs,my engineer said thats what he wanted to see, no welding alowed.If I had a digicam I'd post some photos.I also intend on using an urvan master cyl. as it bolts on to the std booster no probs.

Like mine.
While I don't really think they are any stronger than a welded/bolted together caliper mount, there isn't an engineer in the country that would turn down a good caliper mount like this one.
They are very light but cost a little more to manufacture.

Just thought i would add to the Nissan Urvan master cyl.
The Mitsu Starion master cylinder fits. But when i was talking to the starion guy i was purchasing my MC off he pointed me towards a Nissan Patrol (i think) MC which is a 1 1/8" cylinder same bolt pattern that they use when they go to Wilwood calipers.
With the welding it does depend. For example i was told i can weld the rear brake brackets to the diff, so i think it depends on which engineer you go through.
