R32 Gtr.... V Spec?

[heno]

i just purchased my first r32 gtr. when i picked it up friday the car, when i started it seem to have a miss, but i couldnt tell. it runs like it have a bigger cam. sounds very lumpy. it only does it at idle. does anyone know if there is problem??? when you increase power, typical gtr exhaust note but when cruisin it sounds like it isnt running on all 6 cylinders. i have checked the spark plugs, coils, injectors. i think there my be some sort of air leak. i sprayed some aerostart near the no2 and no3 injector and the car ran perfect for a second the miss was gone and then came back again. also i looked under the rear of the car and the diff has the typical v spec oil cooler fins on the backing plate. does this mean its a vspec??? how else can i tell? can someone help? the car has done 90klm. also with the gtr are they still speed limited to 190km? thats where mine stopped.

[meggala]

yes they are all speed limited. but the r32 ecu is chippable

hmmmm nt you are going to have fun finding someone to work on it though

Fins on the diff don't make it a VSpec. VSpecs came with R33 Brembo brakes and BBS 17" wheels.

kool. thanks for clearing that up. also this car hasnt came straight from japan. i bought it interstate and is a 1993 model. was complied in 2002

Sounds like plugs to me.

Probably need to be gapped correctly.

NRB - I thought that was the V-Spec II?? They used R33 GTR parts on the last of the R32s. Finned diff usually means A-LSD, which is a V-Spec thing.

Correct me if I'm wrong.

You are 100% correct my friend, the last of the R32 GTR's ( 94 late 93 ) they used 33 GTR parts.

[NRB]

Well my 1993 GTR had a finned diff, and it's replacement is also finned :confused:

As far as i know all standard R32 GTR's have a finned diff all V-spec and V-spec II have a flat diff cover so the opposite of the R33's. Best way to tell is the model code V-spec II have KBNR32BFS8 AA where a V-spec does not have the 8 on the end and normal GTR's do not have the S or the 8 on the end.

[KBNR32]

I have a 93 vspec, do non vspec GTR 32's start their model code... with BNR32.... as mine starts with KBNR32.

i thought that was the go as well, only the v specs got the k?

[gtrken]

The miss is no2 inlet gasket has blown which requires removal of the plenum/throttle bodies and inlet manifold.

There are three sets of gasket there and best to replace them all.

Have fun, it's a bitch of a job...

V Spec usually means that it has 330mm rotors and brembo calipers.

Finned diff means nothing...

i have a 89 model with a similar finned diff. i read that the vspecs wern't sold until 93? So that counts mine out as being a v-spec. Mine has nissan front calipers as well.
