brake swap


HAZELNUTRACER

Recommended Posts

Going from an "A" to "B" 4-Speed (I have done this), or from "A" 4-Speed to the 5-Speed trans commonly available in the US, you will have to enlarge the shifter hole in the Trans Tunnel. I also switched to a Series II console (but I don't know if it was necessary, I just had one in better condition than the old Series I console that I had at the time).

I'm not sure what if anything additional is required for putting in the 5-Speed

I also have a 240 and just started looking into upgrading the brakes what year 300zx parts and what year and type toyota calipers?

For the vented rotor swap, you need calipers from a 1988 V6 Forerunner and rotors from a 1984 300ZX. Get the braided steel brake hoses from MSA. They are Earl's brand, some of the best.

Bambi, correct me if I'm wrong, but series A trannies are from Series I S30s (the very first 240z with vents in the hatch, 240z emblems behind quarter windows, plastic storage bins behind seats etc)...

Like I said, these are ones that need modification....

I put a 78 5 speed in my 10/71 240z (series II--round emblems behind quarter windows, diff set back, metal storage bins behind seats)...it bolts up with no mods what so ever....you just pull out the 4 speed (B series?) and just put the 5 speed in its place...the tranny is identical in bolting up (we're not talking clutch components here)....but the body of tranny is identical in relation to the ends and the shifter location...the shifter goes through the hole in EXACTLY the same place as the 4 speed.

The sheet metal mod (or the bent shifter mod) are when you put a later than A series into a Series I 240z (69/70/early 71)....

I'm not at home ATM, and I don't remember exactly when the change from A to B type trans occured. Sometime in 1971 model year I believe. My previous Z (1971, HLS30-23313) had the A type until I put in a 1973 B type trans in it. My current Z (1972 HLS30-55703) came with the B type trans from Nissan.
