GTR front bumper 'N1 slots' / ducts

[Cake]

interested to know which R32 and R33 GTR's have the ducts in the front bumper and which don't, often called N1 slots, located at either side of the number plate? as far as i know, it has nothing to do whether it's a v-spec. maybe it's related to what series it is (1,2,3) etc maybe somebody can confirm.

Only Series 3 R33 GTRs (1997-1998) came with them standard.

If you see any other earlier model GTRs have them, it was either a factory option or fitted aftermarket.

No idea about R32s.

all R32 vspecs came with N1 ducts. As did the N1's obviously

i have a vspec R32.. mine doesn't have the ducts.... can anyone confirm this? i have always wondered myself

[ferni]

Whats the purpose of them? extra airflow/cooling i assume?

Yeah... extra airflow to the top of the intercooler that's usually hidden by the front bumper

I also have a 1994 R32 V-spec II it dosent have the N1 vents and most of the V-spec and V-spec II i have seen do not have them as far as i know they were only an option or fitted as an aftermarket item only the N1 have it as standard. This is also the same as the lip on the boot lid everyone says it was on all 1994 GTRs as far as i know it was also a option part dont know about the N1 though.

[KBNR32]

regarding boot lid.... read through these threads.. it was a nismo GTR standard.. but many R32 GTR owners in Japan have added them to their cars.. from all i know it wasn't a vspec standard item.... u never know could have been an option on all R32 GTR's when new.

I purchased a set of the fibreglass vents for my 32 GTR from Unique Autosprts.

Does anybody have any experience in retro-fitting these to an existing bumper?

The guy who was installing them for me struck metal about 40mm behind the plastic bumber. I assume this is the bumper reinforcement bar.

Is it safe to cut through this to fit the vents? (ie. will this weaken the structural integrity of the car?)

Any help would be greatly appreciated.

You should find that the front bumper support bar should have holes in just the right area. I know the S13s have holes that are perfect for putting those sorts of ducts in.
