Thanks for the posts, Zedicus!

I'm planning on doing this soon but with aftermarket ECU and some ITB.

Prior to reading this I would have been caught off gaurd about the sump swap, but managed to get one in advance.

I've seen big power gain just from ECU and intake swap on a standard 2NZ, so looking forward to what a high comp 1500cc setup is capable of with a good tune.

It's amazing how much the standard plenum and throttle body is a huge bottleneck on these engines.

Great effort and success and nice writeup, I was looking at replacing my mechanical water pump with ePump and noticed that the C blocks were different, which leads me to your post, thanks

1 year on update:

car runs really good, no check engine lights or any issues...EXCEPT!

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.

i should probably mention that the EWP cools SIGNIFICANTLY more than the stock mechanical water pump. i have the majority of the frond air grill blocked off with plexi glass and when we had our subzero winter days it was still all the little engine could do to keep 160 degrees in it.

we did have a 100 degree day last summer but i did not get out on the highway, i did drive around town with the air-conditioner running and did not experience any overheating. i still have the 1 OEM fan in place and it is still connected to the ECU, so it kicks on at 205. but even getting to 205 BARELY ever happens.


also, with premium gas, my MPG is around 36 in town...when i can behave. so about the same MPG as my motorcycle.

the concerns about the fxe low tension rings, no extra oil usage?
factory ecu runs it fine? must run premium (not a big deal)

i found a low mileage fxe at an auction, and figured shortblock , cam swap would be all i need
