I s anyone running Crower 404s on a stock bottom end
B20z.

Thanks
Joe

I dont see why you couldn't. The higher compression in the Z block with the PHK pistons could make a nice combination, TERRIBLE gas mileage though LOL. I don't think you'd have to rev any higher to really make power either.

You have a p8r head,right? omfg I would THINK that would make alot of power

No i have a DHR PR4 PnP head. I'm going to run a 2 layer headgasket and maybe have the head milled too.

I had Crower 404s on my stock B20Z2 and it ran fine but did get bad gas mileage. So yes it will work fine with a stock bottom end.

i made 165/130 on a stock b20z motor crower 404's rocket springs skunk2 IM full 2.5" exhaust and a good header

Well thats good news because i also have a PnP head and a Tri-Y header.

the header i was using was very very similar to the rage headers.... FWIW

Do you have to run cam gears with 404s?

Not really but if you want to play around with them then it's good to have a set of cam gears

you dont have to but youll limmit yourself tuning wise if you dont have them. they only become necissary with a drastic head/deck mill

i figured with the cams as big as they are i would need a set.

Also would it make a difference to have it tuned on 93 or could i keep it on 87.

should run fine on low grade

the b20z requires a knock sensor to run on low grade from the factory so keep in mind you dont have one of those now but the large cam profile should bleed off a bit of compression. if i remember correctly, using dynamic compression with those cams your about the equivelant of 9:1 with stock cams.

Yeah i really dont want to pay 3.79 a gallon.
