A Boy's Love For His Rb20

[djr81]

Having thrown a few brake setups at the old girl, I am hoping this will be my last brake setup that I run for a while

Just need to machine up the mounts so that I can use the callipers with the new 343 x 32mm 32 vane rotors I have on order. Also waiting for Performance Friction to release the new compound of pad I am waiting to run.

Random brake fetish questions:

The Stop techs look all the world like F40/F50 clones. Do they share the same mount dimensions?

Who are you getting to machine the brackets?

Whose rotors you using.

Lastly these folk may be worth trying for pads:

These are the DS2500 pad for F40's. NFI if they match the Stoptechs, however. Note the PFC cross reference.

They are similar in dimensions but as many differences as similarities. They appear to be forged rather then cast. The bolted bridge, the pad retaining clip is the same as the old school Big Red Porsche calipers. The pistons izes in these happen to be the same as F40s. I think mounting wise they have the same offset as the F40s, though will know for sure when I fit them up and trial them.

I am going to draft and machine up the mounts myself and going to use locally sourced 343 x 32mm 2 pce rotors

what size tyres are u running on the 34 rims roy, ive just bought a set from a forum member.

The car has standard guards atm so ill need to get them rolled as much as possible i guess since im thinking of re55s in a 245/40

what are your thoughts?

cheers

I just ordered some stoptech rotors from the states. Far out they are cheap vs brembo and harrop. And the Brembo/Stoptech floating rotor design makes it 100x cheaper to get hats mate up (no need for 20x $20 bobbins)

Mick, I run 265/35's on mine mate, no issues really, just a mild gaurd roll, kind of eats the inner gaurds a bit but no biggy. Edit: I just remembered it did actually grab the LH front gaurd once, but it was during a pretty rough road tarmac rally, hasn't done it since......

so ummmm, has it been on the track of late?

Any news on the plazaman, would love to see if my theory of standard runners will improve your response with a FF plenum. That or I have to take my inlet back to stock and see if I lose or gain anything.

[Roy]

Did a motorkhana the other week, but most likely its next track day will be the Sandown sprints on Cup Weekend.

In the meantime, new dump pipe with bung for the LC-1 A/F meter

The Power F/C isnt tuned to run off the A/F gauge, will see about getting a new one and installing to get the closed loop freeway tune more accurate but not sure if its worth the agro

Also now have my hands on my new rotors,

Mounts are drawn up and will machine them up out of some platic to see if the fit is ok before machining out of billet. Hopefully brakes will be all sorted in 2-3weeks time

Engine wise still waiting to see how dumping the plumb back gate goes for power and then we will try the plenum

You're a brake whore!

[MBS206]

Roy, got any spares of some brakes like that that'll suit an R33 GTS-t

[Yts]

good to finally read this, i had been wondering if you had a build thread rb20's are underated at how good they can be and this build thread proves it good job mate

[Roy]

You're a brake whore!

Your setup has the better rotors. But will be interesting to try these Stoptechs and see if there is much difference between them and the F40s. The Brembos have cheaper and better range of pads as the Stoptechs use Porsche pads and it seems anything with a Porsche part number costs that little bit more

I have a couple sets of spare calipers, Alcons and Brembos....on the lookout for a dedicated track car that they will find themselves on to. Have a set of 4 pot rears that I am building up at the moment that should work really well

I am hoping with the new plenum, Tomei cams, E85 and perhaps the 10cm housing that it will only lose 200rpm response and make 300rwkws with a good spread of torque for a 4,000rpm range. I still have the shorter diff that I can try to get this little 20 on song, but means i would have to go 19s or something on the street to get reasonable freeway cruising rpm. On my 17s it would be pulling 3600rpm on the freeway

They Harrop rotors and hats?

[DJRIFT]

hey roy

what size is that dump pipe? 2 1/2 into 3 or bigger?

and we have a stock internals rb20 down here pushing just over 300rwkw on e85 with a XR6 style bolt on garrett kit on a stock manifold. internal gate ect so you should get what you want on E85

[Ad's]

Hey mate do you have any pics of the old HR31? Im interested to see if i have seen it around before? Nice R32 mate love the volk's i want a set for my car

[Roy]

They Harrop rotors and hats?

Dont believe so, but if they resemble Harrops then its not really surprising as the company making the rotors once had some ex Harrop people starting that side of the business. (what I was told back in 2005ish) They are CSC rotors.

My dump is 76.2mm stainless tube. Wanted to go 4 " but will have to get a custom reducer spun up to go from the small 8cm exhaust housing up to 101.6 tube. Will do that when I do my new exhaust.

I hope Caltex get some runs on the board with the E85, as otherwise I am considering trying one of the new TD05-18G turbos with ported shroud to fatten up my curve

Wholeee bugeesus.... 300 from a stock internal 20! Whooohooo!!!

Hey Damo, is there any e85 servo's in Tas yet?

Cheers

Isn't that car only running E30 ATM?

We run CSC's on the Targa GT-R, and apparently the rotors and hat are Harrops from the Harrop factory. Just a lot cheaper.

[Roy]

Well thats good to know! I preferred the last set I had as they had dark grey anodised hats rather then the silver...but such is life
