well i dunno much about the b20 engines and my new plantform is a b20b. well from the things my friends tell me and from what i have read on the net, the b20 and the ls engine are pretty much the same engine, just that the b20 has a bigger bore... well i have all the parts for my b20b, except for the cams... i am womdering will the crower 402's work?

thx for the info in advance

 

the 402s will work. replace your valvesprings and retainers while you have the cams off, and because you may float a valve if you rev to high.

i see, thanks...

will ITR valvessprings and retainers work? or should i just get the crower ones aswell?

 

If your going all motor i wouldnt suggest that you use crower cams but if you just want em to spice up your power band they work fine. I would suggest Ferra springs and retainers. Or skunk2. Both make excellent products.

I've never heard anything bad with the non vtec crower cams. I've had my 404's in my b20 for a few months and i drive it hard and still runs great. Maybe you're talking about the vtec crower cams? I heard crower had a bad batch but it's suposed to be fine now.

And if you're staying non vtec, i'd suggest atleast the 403's for the cams and get the springs and retainers from crower.

 

yes i'm staying non-vtec and yes, my friends are telling me to get 403's, but the thing is that 430's and up are for all-motor applications... i'm thinking about adding a turbo in the summer, that is why i was thinking about getting the 402's, from what i read on the site, they say the 402s are pefect for turbo/nitrious applications... so that is why i was thinking about getting the 402

 

I believe the 402s will hurt you in a turbo application. You can throw this one at the FI forum genuises, but I think you want a high lift low duration cam for turbo. If you can't wait, I'd get the 403s now and use the stockers with turbo.

 

The 402's are designed for turbo. It's got high lift and low duration. Correct me if i'm wrong but this is what it says on the crower web site. They say it will improve the low end torque and it's gonna spool faster.

But even if i'd go turbo, i'd go with the 403's. VTEC cams works well with a turbo, i don't see why the 403's wouldn't.

And since i already have the 404's. i'd boost it with the 404's and see what it look like.

Opinions?

Their 62402T is designed for non-Vtec turbo, has similar(lower) duration, but much higher lift. If you're gonna spend the money on Crower turbo cams then get these.

 

When i was refering to the 402's, i was refering to the 402T's. Sorry.

 

Not a problem.

If you're going to go NA for awhile and know for sure you're going turbo later then you should go with these cams IMO. They won't hurt performance NA and the specs look really nice for turbo.

 

How well does the B20 work with the 404s? Is top end power greatly increased? Is there any significant gain/loss in the low end? Was alot of tuning required to get them to work well?

 

ya sorry about that, i meant the 402t's the first time i didn't see the "T" at the end

thx for the info everyone, ya i think i'll order the 402T's

 

It works fine. The top end is good and you can really feel that it's a new engine when you hit 4000 rpm and it's pulling hard up to 8k easy. I don't feel there's any low end loss, if there is, it's a very small loss cause it have much more torque than my old b18a.

It was a "drop in and go" in my case. We didn't really have to tune them, i just bumped up my fuel pressure a little but everything's fine, it idle almost like a stock engine (cam gear are set @ 0,0). It's gonna be a little bit lumpier when the engine's cold but nothing to worry about, it's not stalling. BUT, when i'll start playing with the cam gear, i know it's gonna be a different story tho
