1998 R32 (Yes! Thats Right) Impul-R Front Caliper Issue


Recommended Posts

Hi there people, im hoping someone can help me here. I have recently purchased (been ripped ?) an R32 skyline 4 door. The car is a 1998 (yes thats what the nissan motor company plate has as the build date) R32 Impul-R skyline. Now i know the vehicle is an Impul special model, this included a whole bunch of "Factory" upgrades and such. My problem is that some stupid dick before me changed the original 4 spot front calipers to single spot sliders that i didnt know came out on any particular r32 skyline. The rear are still the factory sumitomo (i think) 2 spot calipers with 280mm (i measured) vented discs. I have a set of sumitomo 4 spot calipers to go on front but cant work out what size disc i need. Ive been told i need 32mm thick disc and one on front is 22mm and i think 275mm diametre (i did say it was some dick that changed them). Going by the dust? shield dia. it seems i could go a bit bigger. The mounting holes on both calipers are same width apart but it appears the 4 spot would sit further out due to mounting arms. Any help any one could give that might lead me in the right direction would be of the most help as ive been researching and sending emails to nissan and imul and have had no help. cheers.

If You are looking at the blue plate in the engine bay that says 1998 that is how big your engine is, ie 1998cc or 2l ie RB20. I don't think there is any date on the car. well there isn't on mine.. just grab some callipers and rotors from a 33

R32 GTS-t front rotor is 280mm x 30 (28 min).

R32 GT-R is 296mm x 32

Mount the caliper with a pad installed, and measure the distance centre of hub to top edge of pad. Double to get diameter. Should give you an idea of the required rotor diameter.

OK! OK! Im the Dick ! Lol. Yes i read the plate wrong and it does say 1998 for the engine capacity. People make mistakes and i guess i can sometimes be classed as people! :)

Cheers man, ill give it a try and post results.

Also, if anyone knows if there is a physical difference between the 2 door blinker/ corner lights and the 4 door ones ? are the mounting holes the same ? and pins on plug the same configuration ?

Another question, The factory plate has E-HCR32, i have seen many a mention of hcr32 but not e-hcr32. Any ideas ? or is this what all plates say on imports ?

If i am asking questions in wrong section than please let me know. I have owned turbos before this one, but i am a newbie to this forum so still learning protocol and such.

Cheers to all for thier advice.
