BCNR33 Vs BNR34 front brake caliper threads

Hi,

I have a set of R33 GTR Brembo front calipers.

They came without the hard lines or any brake lines or fittings but do have the "olives" still on them.

I wanted to retain the factory flared hard lines so i bought a set of BNR34 hard lines with aftermarket braided lines since both BCNR33 & BNR34 share the same part numbers in both Nissan & Nismo data.

I tired fitting them to the calipers but they do no't seem to fit due to a different thread on the caliper and hard line bolt,

Do BCNR33 & BNR34 front calipers have different threads?

Thanks!

Mebbe....but I think he means the thread where the brake line goes into the caliper.  I don't know if they are different but I would have thought 99% they are they same. Maybe see if a tap in the thread cleans it up

I did mean the thread where the brake line goes into the caliper.

Anyone knows what thread tap should i use? threads don't look dirty honestly...

I'm starting to suspect the previous owner tapped the calipers to a different thread since no one encountered such a problem.

      Yet another RB Neo misfiring thread after reading all the others.

      By GTSBoy · Posted

      Misfires when the car is fully warm are generally attributed to the coils (and/or the igniter, on cars with a separate igniter). They can stop working properly when they get hot for a number of reasons. Either electric/electronic, or from thermal expansion opening up gaps and allowing HV leakage. Seeing as you have replaced the coils, that could/should rule them out. But I wouldn't always assume so. Were the coils genuine? Or is there a chance you have bought some counterfeit Chinesium shit? Then we're back onto loom connections. They can fail when warm/hot for the same reasons. Inspections, cleaning of contact surfaces, ensuring that terminals are fully inserted, etc etc, are all justified. The same (heat effects) holds true for the other electrics and their connectors. AFM & CAS, primarily. If you try that Chinesium AFM, drive it around on low load until it is properly hot, but do'nt give it more load than you have to, except when you need to see if it will still miss. I'm dead serious about the untrustworthiness of the calibration of those copy AFMs. Injectors are unlikely to get hot unless the fuel is coming back around hot. You could try squirting them with compressed air or freeze spray to cool them back down to see if they are maybe the cause.

      Alright, all the plugs looks good. Noticed that it starts to get bad when the car is up to temp, that's when things starts to misfire hard. next to do is Injector cleaning and such. Got in touch with a shop to do work on the injectors next Monday also help on diagnosis.

      Hence why I've only modified my car into a pure daily. Everything has to remain reliable & roadworthy, while providing value and grin factor. It also must not be handcrafted to the extent that the car will be immovable if something breaks because you cannot get or make a replacement to at least limp around with.

      Nah, I definitely do that kind of stuff with my car. I do drive it around as a daily! It's just that mindset about building a car to actually still use/retain it's function as a car is rare. If you modify your car into a weekender, IMO you've ruined 5/7ths of the fun. It should remain fun to do daily errands in.
