can someone please quickly confirm for me tho;
This is a 610 series 180B yes? That will make it a lot easier for me to hunt down info (your search system here fails).

So far I gather that a direct bolt in front brake upgrade is to use VLT/vs v8 callipers with verada disks. However am struggling to find a straight answer as to what from the 31 will go in.

rear discs?

From eye level, a lot of the parts *seem* to be of similar layout and sizes. I know its leaning too far into absurdity to say it should bolt straight up, but how far off the mark will it be? I understand that the spring diameter from the 31 won't let it fit, but would using the strut, hub and upright from the 31 mate up to the control arms and steering, keeping the 180 spring and top hat? Or just try to get the strut itself in there and leave the rest in place?
And I take it the r31 master cyl won't be a bolt up replacement for the dinosaur 180b one eh? What about clutch master from the 31, and the alternator (not that making custom alternator brackets would be difficult).

R31 might have an internally regulated alternator, with the 180B being external. requires a slight change of wiring if so.

You might have to chop and change a few parts, like using the R31 balljoint on a 180B LCA, or keep the 180B BJ and just slot in the R31 strut. not sure on spring Ø - but the later model 180B struts have the larger Ø spring, so the R31 strut should be roughly the same...? if not, try fitting the 180B spring and hat to the R31 perch - SOMETIMES this work.


Still yet to sit down and have a real play on the car, going to bung on some thermos next week as the battery decided to go swimming in the clutch fan, and the fan decided to donate its blades to the cause. Oh and I believe that the valve seals are knacker'd, but may have a l16 sss motor at my disposal, and from what I've read the l16 head *should* go onto the l18 bottom end; would this be a step backwards for daily power, or would it be better just smashing the whole l16 in and be done with it?
At the very least I imagine the SU's and its manifold will go straight onto the l18 head.

head and carbs (+ manifold) are directly interchangable. the SSS head may give you a better cam (if it's still htere) but the diff between the A87 and W53(?) heads are nominal - mainly port sizes.

And can someone definitely confirm for me the cars PCD? Again, assuming its 114.3x4, but you know what they say about assumptions; I should just get the **** jack out lol. If anyones wrecking a 180b in perth I want your doors too haha.

4x114.3.

Cheers guys

Yep, its too big.

The spring "seat" on the R31 strut is offset on the strut tube as well, which makes it worse.

To fit the R31 struts you need to cut and grind the R31 spring seat off the strut tube and either weld on one off a 1600 / 180B / 240K / 200B / probably some others, or convert to a coilover setup.

And yep, 610 is the official model number for what we call a 180b in Australia. In other countries it could have been called a 160B, bluebird, 2000GTX, etc, but the model number is always 610.
