Roy - I've read similar and considered there might be something in it, but with so many front running FIA GT, Le Mans, SCCA Sports Cars and many of cateogries using them, I figured if teams like that who seach for hundreds, not tenths of a second advantage, monobloc must be the ducks.

Dido, but the metallurgy of the calipers vary greatly. You only have to look at std calipers like the Porshe gear and my understanding is that these are monobloc due to cost of maufacturing.

You look at the race calipers being used in motorsport and the materials used for construction are completely different to those used on monobloc Porsche calipers and some of the cheaper Alcon 6 pots etc.

They have the same size pistons, accept similar sized rotors etc, but the difference between a $6,500 monobloc race caliper and a $800 GT3 6 pot caliper is huge mainly in weight and rigidity, and thats because of the metallurgy of the caliper.

And my understanding is an AP CP555 2pce 6 pot caliper is more rigid and will give better life as well as performance over the Porsche 6 pot...but of course wont come close to the 'race' monoblocs which are not aluminium

i thought brembos were quite rare in the v8 series, with most using ap or alcon gear.

they run a 17 inch rim and fit 375mm discs, which is interesting given that most people seem to go to 18's when they go over about 343mm. i guess all rims are not equal, te37 17's have bags of room with 324mm front Brembos and the template off the ap site suggests they wil take 355s also. 375 is a bit bigger again though...

cheers

AP was bought by Brembo recently.

I know of at least a few teams running 'brembo' branded calipers.

They look similar to this

I think you'll find most of the older AP branded stuff is not branded Brembo as Brembo want more brand awareness of 'Brembo' here than AP

not trying to ruffle any feathers or bag any product, merely repeating what i was told when i was pricing up upgrades (CSC vs AP) by a reputable brake outlet (wont name names, but race brakes are their specialty) "CSC brakes would make a a good boat anchor".

i was keen on the CSC's due to the price, and ive never used them so im not baggin them, but anyone know where those sort of comments couldve stemmed from?

a certain brake shop known for race brake works is sometimes more biased to their products.

Frm a bloke not selling them...who perhaps hsa a vested interest in selling a different more expensive brand?!?!?!

At the end of the day, they are almost a bolt on option, they take std Porsche pads so there is a huge range of compounds available. They run a 343 x 32 mm rotor with a good sized 4 pot caliper.

Based purely on the rotor size they would make a great upgrade. The caliper cant be any worse then the old std equipment Nissan 4 pot (id say the CSC is markedly superior to anything the Nissan factory have ever thrown on a Nissan)

And at the price they are abloody good upgrade. The real question is could the average unter really tell the difference between say an AP 4 pot caliper or a CSC 4 pot caliper on the same sized rotor with same pad material? Oh hang on the most commonly available 4 pot AP street caliper is only suitable for a 28mm rotor!

So baot anchor? Nothing is ever clear cut, and i havent run the CSC but there are plenty in Voc that do, and the owners i have spoken to have all been happy bar one...who was happy with what they did considering the price, but not the ultimate result.

Brembo does own AP racing but they are run as two seperate companies, competiting against each other. SBR and FPR both use Brembo.

There are commonly avaliable AP calipers that take larger than 28mm discs, they can also be spaced.

look at www.apracing.com they have alot of good info on there

it also depends on what you want to do with the car, ie fast road, track work. different setups will suit different people.

There are commonly avaliable  AP calipers that take larger than 28mm discs, they can also be spaced.

If you go to most brake places, the most often offered caliper is the CP5200. It takes from memory a 330mm diam rotor up to 32mm thk. Off the shelf without the spacer they take a 28mm thk rotor. To the best of my understanding they are around the $800-900 each. So looking at the $2200 for the CSC, its great value for a kit including radial mounts, slotted curved vane rotors with hats and of course the calipers and Bendix pads.

Not saying AP arent great, or that they are poor value for money. Im just saying that the CSC 4 pot kit is great value. The 6 pot at $3500 in my eyes doesnt represent the value that an AP kit using the CP5555 6 pot caliper but you are 100% right...its horses for courses :)

...We'll I've got CSC and I'm happy. They will be put to the test in my GTRs first circuit meeting late this month. What sold it for me was that if they were crap, even slightly rubbish, Simon Gishus from Nizpro sure as hell wouldn't be putting them on his cars!

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
