Hey man, I'm using a booster out of a b13 Sentra in my vh s13. The overall diameter was more than 2 inches different if I remember correctly, some stated my brakes would be less powerful but I felt no difference, hope this helps.

I'm using the B13 booster as well. Use the non-ABS one if you go that route.

I did notice the pedal is softer now than it was before. That could be because I am using B13 booster-300zx MC-Q45 calipers though. I've got an automatic booster I am going to try out this winter to see if it fits.

This is on a n s13 Btw but I think the Engine bays are close enough that it wouldn't matter

ok so with a little bit of help from a good friend here on nico i have chosen the b12 87' sentra booster. it is a full 2" smaller in diameter, the only downfall is it is about 15mm thicker in depth i.e. (fire wall to mastercylinder thickness). so here are some pics for you to compare.

Would you mind measuring the diameter and depth for me? I'm thinking it's still going to be too big for what I need but there's a chance...

Thanks in advance!

Ok the booster is 7.5" in diameter and the measurement from firewall mount to the master cylinder is 75mm in depth

Let us know how the brakes feel after you get that in and the car running. I'm not satisfied with the pedal feel.

Awesome...thanks! I hate to keep pestering you about the remote oil filter adapter pieces you were talking about making, but is there any chance you can have one done soon? If you make one I'll buy it but I need it within a few weeks. No biggie if you can't do it....but it would save me some work over modifying the factory part with AN fittings. ;)

Ok So my stock s14 booster never worked right before so for me the booster works great, I had a hole in my diaphragm and it felt like I only had manual brakes. Pedal feels great and is very responsive.
And about the oil blocks I haven't had any time to get my machines up and running. But I will be working on them this weekend, so I will be in touch tmorgan4. Did you want -10 or -12 fittings? Lmk thanks

Awesome! I'd definitely take -12 fittings. I can definitely purchase fittings too so it's less stuff for you to buy up front.

This is...assuming these aren't going to be crazy expensive! :biggrin:

I would like to know as well. If it's the one that bolts on directly to the block that would help me out with some of my piping.
