Hep With Identifying These Parts R32 Gtr

[OLLIE_NZ]

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

The doover in the 2nd pic is the coolant temp sensor for the A/C. Guessing you don't care for A/C while racing.
