Yup!

Words of wisdom Pete. Benny, my car isnt on my rotisserie at the moment but I will need it soonish so you can copy mine if that helps.

Bugger! Ive changed the thread name to reflect 240Z manual only. Thanks Mike.

I would doubt it Scoota, there are two layers on the firewall plus the pedal box behind that which is also braced to the plenum area . So you have 3 layers that are pretty well supported, I doubt that foot pressure would ever stress it with a couple of extra holes drilled. Engineers "like" to see matching components as it gives them some reassurance around braking capability and front to rear balance.

Confirm stud spacings are 80mm wide for both 240 and R33 boosters. 240 studs are 70mm height. R33 studs are 60mm height.

Agree with Gav on this. Only really easy to see rust in the photo's is in the rear hatch and it doesn't look that good so the rest would be suss. Having said that it looks like a genuine and complete car so for the right price would be an excellent start.

Thanks Mike, I will measure up the pattern and confirm. Yep, did look at swapping the clevis on the rod but the R33 is 10mm rod vs 8mm for the Z.

Thanks Dimitri. Yep fair call, lets confirm clutch MC fitment and a road test before sticky.

I don't think pedal stroke is really relevant, if it was a clutch system yes but if you're using all your pedal stroke with a brake system you've got big problems!

Thanks Pete, I will keep it up providing you have another go! By the look of it Ive got more room than what you had for the clutch MC. When I pull the engine next time I will throw the original clutch MC in to confirm. Cheers.

Please explain?

Did this today....... http://www.viczcar.com/forum/index.php/topic,12030.msg123132/topicseen.html#msg123132 Worked out pretty well and Ive got adequate clearance to the rocker cover. Also a shot from inside of the base of the steering column.

I cant get a good shot of my MC so Ive grabbed images of the web. 1st one is the same as mine, which I think is ABS. 2nd one is also R33 but non ABS, I think. Either way just buy the correct one. One other thing.... the rear outlet is for the front brakes and front outlet for the rear. They are clear stamped but take note this is the opposite to the standard Z arrangement.

Meant to add....... The R33 booster is about 215mm wide so this will put it very close to the clutch master cylinder, I cant get in there to measure definitively so suggest you do some checking if you plan to do the same. Isn't an issue for me because my clutch MC is now under the dash as Ive got a cylinder head in the way! Also a shot from the inside.

Before you bolt the booster in theres one more thing to do..... The clevis pin on the R33 pushrod is 8mm and the hole in the Z brake pedal is 10mm so you need to either fill and redrill the Z pedal to accept the smaller pin....or drill out the R33 clevis to take the larger 10mm pin from the Z. Needless to say its much easier to drill out the R33 clevis! The R33 clevis is also a little wider (only about 1-2mm) meaning the clip wont fit on the Z pin so a bit of a squeeze in the vice and its all good. After bolting the booster in I only had to adjust the pushrod about 3mm to match up with the hole in the Z pedal. I wont be able to actually test this on the road for many many months but I don't see any issues that would stop (ha ha) it being a good alternative.

I'm going to run R33 GTS-T front calipers and R31 rears on my car so I need to go to a bigger brake MC and it seems that 15/16 inch is the way to go. Ive looked at the old style patrol 15/16 MC's etc but my original 240Z booster looks pretty bad so I was in the market for another booster as well. Additionally the engineers like to see matching brake components where ever possible, plus the 240Z booster is pretty small so may not give the desired amount of assistance. I had done some preliminary research and when Jamo posted his R33 GTS-T booster/MC for sale so I jumped on it. You can pick these up for $100 on evilbay easily, so they are a good alternative to the Patrol set up and you get a much newer booster as well. Now a few disclaimers: This master cylinder is called a BM44, search ebay and you will see it is used across R33 skylines in ABS and non ABS versions as well as S13/14/15 Silvia's. There seems to be a few different versions of the basic BM44 MC so you will need to ensure you get the right one (see pic's of mine), I'm pretty sure mine would be the ABS version as I would guess only the lower spec R33's would be non ABS. I cant vouch for the stud pattern on the back of the booster for the Silvia's but I reckon they will be the same. I also don't know if this will work for a 260. The width of the stud spacing on the R33 booster is the same as the Z but the height is different, also the stud pattern on the Z booster is not centered whereas they are on the R33 booster...see pics. This means that you can use the original lower holes in the firewall but need to drill new holes for the top studs. The booster came with a paper gasket which is a handy template for the new holes, a few minutes with a drill and you can slide the booster in, the nuts are really easy to get to under the dash so its very straight forward.

Come on Simon, where's you sense of adventure?? Gravel Rd....tell me about it.

240Z = 1045kg so 4.1 Litres

Rolling = feel good. Nice Lurcho's

New Mod working well!

Theres a plan....I'm game if you're gay.

Im going...no Z though

^^^^^ What he said.

Congrats Mark

Hey John. Whats the go??? We on for this weekend?
