Hi guys,

A friend and I are building an R32 GTR circuit car.

We've just pulled out the ABS and also the Brake master cylinder and brake booster as we're installing a pedal box and also to make room for the roll cage to come through the firewall..

A couple of questions if I may.

- The brake booster vacuum chamber that sits off to the far left of the engine bay that runs to the brake booster has just been pulled out. We're not sure what to do about the air leak we now have since removing it (we've blanked the hose off so it's not just sucking air in) but we're wondering/hoping we can just leave this blanked off and it will cause no problems, is this the case? (see first pic)

- We've just pulled the heater and air boxes out from under the dash also, the water hoses that run through the firewall for the heater have been pulled out and we have just put a U shaped hose off the side of the block where the old heater hoses used to run from. Halfway along one of the heater hoses is what looks like some sort of temperature sensor of sorts (see attached pic) as we're removing anything we think is not necessary we're hoping we can just remove this sensor and everything will still run fine. What is this sensors purpose? (see second pic)

Thanks guys.

Yes, you are OK to just block off that vacuum hose. You can remove the vacuum resoviour you circled as well, no longer required.

The sensor in the heater lines must be related to the heater controls- the engine coolant sensor is at the front of the inlet manifold. For a race car you can disconnect that as well.

BTW, you should start a build thread in the build section - there are lots of people interested and experienced in race car builds here

      R33 disk brake size

      By Duncan · Posted

      If you are keeping the current calipers you need to keep the current disc as the spacing of the caliper determines the disc diameter. Have you trial fitted the GTS brakes fit on a GTSt hub or is this forward planning? There could be differences in caliper mount spacing, backing plate and even hub shape that could cause an issue.

      Help Understand GTT Boost Setup

      First up, I wouldn't use PID straight up for boost control. There's also other control techniques that can be implemented. And as I said, and you keep missing the point. It's not the ONE thing, it's the wrapping it up together with everything else in the one system that starts to unravel the problem. It's why there are people who can work in a certain field as a generalist, IE a IT person, and then there are specialists. IE, an SQL database specialist. Sure the IT person can build and run a database, and it'll work, however theyll likely never be as good as a specialist.   So, as said, it's not as simple as you're thinking. And yes, there's a limit to the number of everything's in MCUs, and they run out far to freaking fast when you're designing a complex system, which means you have to make compromises. Add to that, you'll have a limited team working on it, so fixing / tweaking some features means some features are a higher priority than others. Add to that, someone might fix a problem around a certain unrelated feature, and that change due to other complexities in the system design, can now cause a new, unforseen bug in something else.   The whole thing is, as said, sometimes split systems can work as good, and if not better. Plus when there's no need to spend $4k on an all in one solution, to meet the needs of a $200 system, maybe don't just spout off things others have said / you've read. There's a lot of misinformation on the internet, including in translated service manuals, and data sheets. Going and doing, so that you know, is better than stating something you read. Stating something that has been read, is about as useful as an engineering graduate, as all they know is what they've read. And trust me, nearly every engineering graduate is useless in the real world. And add to that, if you don't know this stuff, and just have an opinion, maybe accept what people with experience are telling you as information, and don't keep reciting the exact same thing over and over in response.

      How complicated is PID boost control? To me it really doesn't seem that difficult. I'm not disputing the core assertion (specialization can be better than general purpose solutions), I'm just saying we're 30+ years removed from the days when transistor budgets were in the thousands and we had to hem and haw about whether there's enough ECC DRAM or enough clock cycles or the interrupt handler can respond fast enough to handle another task. I really struggle to see how a Greddy Profec or an HKS EVC7 or whatever else is somehow a far superior solution to what you get in a Haltech Nexus/Elite ECU. I don't see OEMs spending time on dedicated boost control modules in any car I've ever touched. Is there value to separating out a motor controller or engine controller vs an infotainment module? Of course, those are two completely different tasks with highly divergent requirements. The reason why I cite data sheets, service manuals, etc is because as you have clearly suggested I don't know what I'm doing, can't learn how to do anything correctly, and have never actually done anything myself. So when I do offer advice to people I like to use sources that are not just based off of taking my word for it and can be independently verified by others so it's not just my misinterpretation of a primary source.

      That's awesome, well done! Love all these older Datsun / Nissans so rare now
