Clutch Master Cylinder Hitting Plenum!

[Char]

my car is at the workshop and the rb25/20 clutch master cylinder that i have in my car is way to long.

its an R32 with a Greddy plenum.

ive rang about 4 places today and they couldnt give me any answers.. one bloke told me to look into a datsun 1600 clutch master cylinder but he's never tried it.

the shop measured a 180sx clutch master cylinder n that MIGHT be short enough but the only one i could source was from autoone and it was 9.5cm -too long. nissan couldnt give me lengths just part numbers.

anyone know what i can use?

need help asap

cheers!

33gtst, have to modify the shaft though, IIRC need to shorten it by about 10mm

i had the same problem with my build 25/30 into 180sx, i ended up using a s14 clutch mastercylinder, and had to chop the back out of the greddy plenum to get it to fit.

My mechanic had to shave the rear of my GReddy plenum to make it all fit. Didn't affect the tune or performance at all though which was good. But we later found out that an R33 GTS-t Clutch Master Cylinder would've done the trick. Oh well...

I used a r33 clutch master, no inlet manifold grinding needed.

thanks for the info!

we used an R33 GTST clutch master and it fitted perfect! its half the size of an rb20det one

-tho they did have to fiddle a bit to get it in i believe an engine crane was used to lift the engine out of the way first
