My next project: 5 lug & brakes!

[Bumnah]

Step 01 was the engine swap (sr20). Now the car goes, but doesn't exactly stop. I put in new rotors and pads in the front when I did the swap (cheapest I could find @ carquest) to tide me over until I could do my real brake swap.

What's in the works?5 lug conversionz brakes all aroundz rims and tires.

Parts gathered:

5 lug hubs front and rear. New hubs and wheel bearings. Def. need to be replaced on a 15 year old car.

Powerslot rotors front and rear

Z32 Rear calipers

Ferodo DS2500 Front and rear brake pads

G35 Coupe Ebrake lines

An idea of what they'll look like:

Z32 NA rims. Street rims. Eventually upgrade to lightweight 17s.

New 1 1/16th brake master cylinder.

What else is needed? Front calipers & tires to get the setup in and running. I'm planning on getting longer wheel studs (ARP) and some light weight lugnuts. The rears need new hardware kits already, I'm thinking about going for the whole rebuild and powdercoating deal. That's still up in the air. I've already got the conversion lines to use z32 calipers on a 240sx. Just didn't remember to take pictures of 'em.

I settled on the pads by talking to some friends who know more about this stuff than I do. They really recommended them if I was serious about tracking my car for real. I have z32 uprights as well for the rear, but I'll wait to put those in until I can afford to do my suspension setup.

I really can't wait to get these things on. Even doing some spirited driving on back roads the brakes do not give you confidence. You really gotta give yourself some room, or else you'll put yourself in a tree.

I will keep updating this thread as I progress.

Thanks for looking.

nice parts! Even though its obvious for some of them...can you please post a list of ALL the parts needed for the 300zx front and rear brake conversion? (s13).

Thanks

[crash n burn]

now i'd like to get a set of new hubs for my 5 lug instead of the salvaged ones i got..

was there any option to have them with the abs teeth ring along the other edge

or anybody know this for that fact?

//edit// deffinently not trying to thread jack, just asking if you knew, if not..if anybody else

[nwmrkt]

also do you keep the ABS when doing the brake swap?

[crash n burn]

hell, i am..complete 300zx brake system, abs included...gooooooood god stopping on a dime

plus i wanna get those bracket adapters to run the larger supra rotors, i think its thats it

[Grim_Fandango]

actualy if u get skyline rtors theyl fit right up with the brakes without brakets i dunno if there bigger than what u got thoughi changed mine to R33 brakes,rotorsand line's(even the hub in the back) and my car break like there is no 2morow

[Bumnah]

Thanks.

I didn't check up on the ABS since my car does have it.

I haven't personally looked at how the teeth for the abs sensor are mounted on the hub. But I speculate that section can be bolted and unbolted and moved around. Or it stays on the spindle (upright) and you can swap the hubs/bearings as needed.

As for the parts? Everything I've pictured is what you'd want to do the brake conversion and the 5 lug conversion.

All that is missing are the front calipers. I need new tires to go on my rims but other than that she's almost all pieced together.

You need conversion lines to connect the z32 brake calipers to the brake system hardline.

I'm replacing my brake master cylinder with a z32 unit as well, so when I have the whole brake system open I'm upgrading to Motul brake fluid as well.

These are just extra things. To be cost effective. You can get rotors from the local autostore (I favor Carquest). You can also get regular pads instead of performance pads.

You can also get 5 lug conversion by using z32/s14 parts. I chose to get new hubs to replace the 15 year old hubs and bearings.

I can't wait to feel these brakes when I get all this put together. It'll be nice to have a nice set of tires on the car for once as well.

.....................................yeah, but when does the blue dash get put in??

[Bumnah]

when i do a ka24e engine swap and my conversion to geo metro brake, paint my car primer black and a mixture of dented/rusted fenders. at that point the only option would be a blue dash with red painted vents.

ps. please view garage thread.

3/10. i really expected more from you.

i expected more from your mom too, but expectations can exceed the outcome, its a fact of life.....much like the fact that your hate of my blue dash (and all that surrounds it) comes from a very deep seeded emotional issue.....and i think suicide is the only answer.

[nwmrkt]

do you use the 300zx ebrake? Isnt is a drum setup?

[Bumnah]

yes. z32 drum ebrakes. i just don't have them pictured.

i hear the skyline rotors are a little larger, i was thinking about this when i had an opportunity to buy a front clip, they were gonna throw in the brakes and rear end for me

but the abs teeth are as so, you can tell on the non-abs hub where the groove is

[Bumnah]

Update time!

Got my calipers in. Bought 'em off of an ebay seller. Aluminum 30 mm. Rebuilt, and painted Hell Yeah I street race! Red.

Z32 Front calipers]

The Conversion lines. Picked 'em up from FRSport

Motul 600 Brake fluid. Get it all at once I say.

All that's left are the ARP longer wheels studs, new lug nuts, and tires. I'm not sure if I'm going to rebuild my rear calipers or just clean them up. I want to paint the rear a different color than the fronts. I'm thinking lime green or something.

Hopefully in August I'll have my parts together to get this stuff done.

Thanks for looking.

[nwmrkt]

nooby question...the 5 lug hubs like Ichiba do they have include new bearings? And why do you need longer wheel studs?

Thanks

[Clawhammer]

I just did this last week as well as some SPL arms. I went with S14 SE's obviously. Have fun!

[Bumnah]

the ichiba hubs do come with bearings.

i'm going with longer studs, if i ever need to run spacers or anything. i wouldn't have any problems. putting in longer wheel studs with the hubs installed to the spindles, you'd have to take it all apart to reinstall.

hahaha. I dont know why but its funny. Sorry

actually ichiba hubs some with longer than OEM studs. I would say like 5-10 mm longer

you forgot to mention you either have to mate your s13 cable to the z32 parking cable to get a working parking brake. Or you can buy 2+2 cables and mount them in. Although putting the 2+2 cables do require a little creative mounting as they are slightly longer than the s13 cable.

dont forget to mention the car won't stop in shorter distances even with a great brake system if the tires cant handle. The car can't stop if they tires dont grip.

AA traction FTW

[Bumnah]

i've forgotten to picture the actual parking brake assembly itself also..

for the cables I"m running the g35 coupe ebrake cables. those are pictured.

[eazye2000]

Sweet! It's looking good, my friend. Keep us updated!

[Clawhammer]

Unless you're locking the brakes, what do tires have to do with it?

[Clawhammer]

http://www.bumnah.com/^Do we even want to know about this??

[Bumnah]

braking is the friction between the tire and the road. if you tires can't maintain grip the biggest brakes in the world won't do you good (brakes aren't touching the ground) tires are the most important part when it comes to braking.

the advantages of having bigger brakes is how resistant to heat soak they are. bigger rotors/calipers can absorb more heat without fade then smaller brakes.

on the street you really don't need anything more than what the manufacturer recommends, but on the track you'll find the flaws of your setup more quickly.

[working4aS13]

Bumnah:

You are brave to drive an SR on stock 240 brakes. Also I have a question for you. The G35 e-brake cable you are using, that just bolts up? Or at least you don't have to hack up the cables? I've never come across that information before this thread and I thought I did a fairly sufficient job in researching my options for the 240SX. What is your source of information? I ended up using Z32 2+2 e-brake cables which I had to cut to shorten the length, although in hindsight I think I could of used Z32 coupe cables.

Also I think it worth mentioning you are going to have issues with those Z32 wheels on the front of your S13, at least without spacers. When I mounted mine there was about 1/2"-3/4" between the wheel and the strut. The tires will undoubtedly rub in corners if they aren't touching the strut when you mount the wheel. For a short time I ran with a staggered setup S14 SE wheels on the front and Z32 NA rears, great stable stopping distance but at the expense of acceleration due to the additional weight.

The rear rebuild kit for the Z32 calipers are no longer produced by Nissan USA you obviously will have to purchase some aftermarket ones unless you intend to go to Japan to get them. Z owners generally recommend Centric, CoZ sells them.

Also have you done an inspection of all of your ball joints? Having an entire project held up by a ball joint on order would be annoying to say the least. And just a suggestion, if you are going to be disassembling the rear axle setup you might as well do an ES bushing swap. Yes, its an additional ~$118 (if you order from Summit Racing) but you'll have a much stiffer suspension.

ABS Questions/Speculation:

Personally I didn't keep my ABS system when I did my swap. I actually removed the actuator and installed the stock non-ABS lines. I don't regret taking the ABS out but occasionally in the rain I suppose it would help. I can lock up all four tires on either wet or dry pavement. The rears always lockup first. But like Bumnah said its really what your wheels are wrapped in that stop you. With that being said my rear tires are junkers as this is my first rear wheel drive car and realize I'm a little hard on my drive wheels on my vehicles. The fronts will lock up on dry pavement with enough pressure on the brakes (17/16" Z32 master cylinder installed) they are wrapped in Eagle F1 GS-D3s.

I don't think you could keep the ABS anyways. I'm fairly sure the ABS sensor wheel on the front from a S13 is a different diameter or teeth from the S14. And IIRC the connectors are different and that was enough to dissuade me not to mess with what I consider(ed) a useless system for me. But at least if you are going to pursue keeping the ABS you won't have to mess with the rears as the sensor is on the differential.

crash n' burn:

In regards to the Skyline brakes. Yes the R32 GTR, R33, and R34 are larger but again like Bumnah mentioned larger diameter/width adds to the heat absorption. BUT I've never experienced brake fade and I've done track runs on the rotors/pads that came with calipers which were in no where near new condition (had about 180k original miles IIRC). That is not to say that you or some other person won't experience brake fade with a Z32 front and rear setup on an S chassis. But if you seriously want to entertain the idea of putting Skyline brakes on your 240SX I would suggest considering all the costs involved. The rotors are special order and quite expensive and then you have to source some calipers. Also you have to consider you are adding additional rotational and unsprung mass. Although I understand the fondness for the aesthetics of the Skyline calipers over the Z32's; not to mention the 'coolness' factor "Yea I have a bit of Skyline in my 240."
