how are there compared to 403s?

Re: crower404s
 

way better, but get the 405's they makes sweet power.

405's???

Re: crower404s
 

I prefer my 409's :)

Re: crower404s

Re: crower404s
 

your such a piece of asian ----

Re: crower404s
 

well, apparently there are 405's....

but modifications to the head are needed to make it fit.....

its for an all motor setup i guess..

Re: crower404s
 

I have 403s and PR3 pistons in my my car and its a great combo and runs hard, but they don't compare to the 404s/PR3s....the all motornon-vtec B20 I'm now building will have Crane #20 cams and 12.5:1+ though, if you're looking to break 200whp in a non vtec those are the cams to use apparently and less "bother" than the new 405s

Re: crower404s
 

is the 404's to rough for daily.

Re: crower404s
 

IMO "rough" is relative...you will notice the change in idle but in my honest opinion it will not bother you that much. its well worth it. my 403s untuned idle around 1100-1200 when cold..its a little rough but only during real cold starts. 404s and the PR3 or P30 pistons are a great combo for a nice non-vtec street car!! what exactly are your plans??

Re: crower404s
 

well....my motor is pretty fast for what it is, i have a b18b with i/h/e b16 tranny,lsd, 6 puck clutch, 11lb flywheel and i have a friend selling his 404's and a set of crower valvetrain to match em, but i wanted to be safe and learn a bit more about em before i get em anyways i wanted to boost again before spring time but i dont know yet i have a kit laying around i could put n my car but when i seen this guy in a eg with a ls with 404's and a 65 shot hanging with a boosted b16 crx it just makes me wonder how well those cams and boost would work together.

Re: crower404s
 

go check the B-series forums over on non-vtec.com ...all the 403 and 404 info you need....from what I know, people only suggest the 404s with higher CR with CTR, PR3s, P30s, etc. pistons. but if you have stock internals, 403s would be a better choice for a stock compression LS. but if the deal is right for the 404s and valvetrain then go on and get it! and the 404s are not suggested to be used with boost at all.

Re: crower404s
 

just go with the 404's, thats what i would recommend. they idle pretty good with anything over 11.5 compression.

Re: crower404s
 

So the cams help alot I am guessing. Since everyone now seems to be buying them.

Re: crower404s
 

i DD my 404's, only 9.6:1 cr. put down 165 with only bolt ons and the cams in a b20z.

next up is a p8r head and 11:1

Re: crower404s
 

lol thats funny.. i'm selling you a p8r head on honda tech.

Re: crower404s
