Hi, I'm Dan.

Recently bought MR30 Hatch, really like it. Not many around Brissy.

I want to upgrade the brakes and suspension.

Suspension will be King Lows, with struts to match (have pedders for front, some yellow things for the back)

Brakes are ok for a daily work car, but after a few heavy stops it fades pretty bad. Have had fluids flushed and changed to Nulon DOT4, seemed to make a very small difference.

The L24 is going to be turbo oneday soon (have bout all the parts, just need to lock or limit the dissy to stop it advancing)

I have read about import struts and R32 this and that. Its all too expensive for me (im on $400 a week) Plus im not the most mechanical minded, have limited tools and stuff. Still learning as I go.

Im thinking some slotted/vented disks, uprated pads (like the EBC red or green pads off ebay.uk) and stainless/braided brake lines would be an improvement?

Has anyone undertaken a 'factory' type brake upgrade like this before? I have contacted a few places but they all ask for the MR30 disk DIA, which I dont know.

Would it be better to upgrade to R31 disks and calipers? I have read previous topics but there didnt seem to be a conclusive answer.

(Also, part number for standard aus R31 pads is DB1105, but DB1085 is the equivalent part and is a commodore pad. And being a commodore pad there is a MASSIVE range of pads available)

Can also use 'RB74' but they have many reviews of ALOT of brake dust (I wash at least weekly so thats not too bad)

I have seen R31 setups go for $150, which seems pretty good.

Finally, If the R31 pads and the R30 pads are similar/same, does this mean the upgraded pads for the R31 will fit the R30 caliper?

Quick note:

Aus MR30 Disks

http://www.dba.com.au/products/dba317sl $249 each

Aus R31 Disks

http://www.dba.com.au/products/DBA615SL $149 each (plus $30 shipping)

Bendix Ultimate Pads have been reccomended for the R31 calipers, at approx $130 for L & R front. (Also dont forget the

Looks like going to R31 is a better idea even based on cost of replaceing components ($200 saving just on disks)

Ebay has a few sellers that seem ok:

EBC Green Pads R31

Also note:

R31 wheel bearings part No. K1168 R31 Bearings

R30 wheel bearings part No. K1145 R30 Bearings

Both $43 posted (seems a bit much)

I am looking at picking up a set of struts this weekend to test if the components fit the R30, I will let you know what happens.

good point about the overall cost of replacement parts too. Didnt even think of that!

I was at one point looking at Commodore Caliper and 'insert unknown' deisks, just it was too much fugging around to get the right disk. Commo parts are cheap as too...

AND let me say ................... No modification is cheap if done right the first time around.

Bang for your buck ............ the VT Commodore front conversion is the best your going to get and you get a 2 spot caliper to boot, but the initial outlay can be a bit costly unless you have free access to a reasonable machine shop, or are prepared to pay to get the machining done.

There is DR, but DR30 front struts have to be sourced and new discs are nearly impossible to find and DBA have ceased production.

And you don't need to do anything, but change to good quality brake pads that are g'teed to at least 550 degrees.

I cant see how Commo conversion is going to be cheap as there is no info on what the actual parts required. It will have to be trial and error, then wasting money on hub coversion to suit disks which havent been proven to work!

Anyone have actual info or is it all just too hard on this forum!

u can do the s13 upgrade 4 cheap, do a search, fairly easy and cheap, you gain 4 pots and heaps of options of rotors to use, if yopu dont wanna do that try find sum dr or hr struts (100mm brake spacing) and have them modded to suit coilover, k sport do a cheap kit, didi it to a mates, works fine.

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
