it prevents firewall flex for a more responsive braking. I have never had one but did have braided lines on my VL turbo which were great. Stopped on a dime it did.

Is there any reason I should not be doing this?

Possibly, but they won't be particularly good ones from a performance standpoint.

I've asked my mechanic to install one on mine, and he's hesitant to do it because it means he has to drill into the bodywork and it'll ruin the look.

If I can get a nice-looking one made up, I'll tell him to do it anyway and just leave it in the car when I sell it.

But it won't affect your ABS or anything.

What it does is stops your brake master cylinder from moving around, either from the force of the brake fluid being pushed through it, or G forces acting upon it and its mounting points. That kind of movement can affect braking feel and performance.

If you hunt around abit you can actually get a brake stopper that is part of your strut brace.

I remember having a Cusco strut brace that had the master cylinder brace built into the bracket of that so it was all a neat fit with no extra holes required (from memory).

yeah the one that i have is part of the strut brace, very neat. the stopper uses holes that are already there (for the R33 at least) - they normally have plastic covers over them standard.

the reason i ask this question is after using the stopper for the past year, i noticed on perfectrun.com.au that for some cars they say "OK FOR ABS FITTED MODELS" but for skylines they have no comment.

I wasnt going to start a new thread, so i will hijack this old one.

I have just installed a brake clylinder stopper and the instructions were in japanese.

I am wanting to know how much you tighten the main bolt to the brake cylinder.

i have it on fairly tight or should it sit just off the cylinder.

Do you need to drill any extra holes or anything for the Cusco stopper on a R33? I was under the impression that it is a direct bolt on item with no modifying needed??

No drilling required, the holes are already there nicely threaded. :P

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
