The stage 1 EXEDY clutch is absolutely TOAST. on 3/14/2021 i pulled the trans and replaced the exedy with a McLeod Street Elite. i wish i would have taken pictures but i was in a borrowed garage and just did not have time. The exedy disk surface was not too bad but had been very hot, the hub and springs were trashed. the springs had been stomped mercilessly and were crushed and nearly falling out of the housing. even the splines in the hub showed significant wear. the pressure plate had gotten hot enough to deform and cause the through out bearing to ride and groove it. THANK HEAVENS i had put a fidanza flywheel in last time, it had gotten warm but was still fine.

if you do a similar engine build rather it is complete prius, or prius rotating assembly you MUST get a GOOD clutch. the EXEDY stage 1 is rated for +30% HP over stock and it slipped almost instantly. i nursed it and got almost 1 year out of it. the new McLeod clutch makes the car feel amazing, 2nd gear chirps the tires just messing around, first gear makes me wish i would have put an LSD in it while it was apart. the McLeod is rated for +50% to 70% more HP, has a massive hub and spline area, and much higher clamp load. there is a little more clutch feel at the peddle, if that bothers you, well too bad.

after the last couple months of nursing the clutch, the little toaster is exciting to drive again. watch out CIVICs, the streets are MINE.

NOTE: due to location, mostly it is guys in diesel pickups that always want to race me.




with the slipping clutch i have avoided doing ANYTHING that might increase HP more. Now that the clutch is fixed i will be doing an intake and exhaust sometime this summer. and hopefully i can make it to a dyno in Denver. i am going to play dumb and when it shows 130hp to the wheels or something crazy for a 1NZ i will just nod and say cool, and drive off.

Do you still have this xB? I have one and would really like to follow in your footsteps. Could I use the 1NZ-FE block with the FXE cylinder head and pistons?
