Ok,thanks. And what you guys think I should do firstfor my engine setup. My options are: 1. Get AEBS intake manifold and 62mm TB or 2. Get stage 1 crower cams. And why? Thanks.

 

The cams will be a more noticable difference.

I am running the stock TB and IM on my setup and really don't need a larger one. Unless you have the mods that would benefit from a larger manifold and TB, there is no reason to upgrade. Your low end torque will most likely suffer as well.

 

Can I use crower stage 1 for my setup? Cause someone told me if I use stock pistons,I shouldn't do that,is that true? Also is it worth it to get stage 1?

 

I'm sure you can. Upgraded springs and retainers would be a good idea so that you can raise the rev limit to take full advantage of what the cam has to offer.

Raised compression isn't mandatory for Stage 1, but it would help out a lot.

What are your power goals?

 

Well,I don't have a specific power goals. Maybe 200HP at wheels,is it possible? My head is aready milled by 0.03 (cause B20B engine block is very low compression) and all internal are stocks. Do you know how many HP increase with stage 1 cams? stage 2? Just roughly if any one know.

 

200 whp with stage one cams and stock compression ain't gunna happen.

You should think about a higher compression ratio coupled with stage 2 cams and some good tuning and you will come pretty close.

 

Ok,thanks. What compression ratio I should make? And for my setup with the head milled 0.003+stockb20b block,what compression ratio I have now aprrox.?

 

Use www.c-speedracing.com for the compression calculator. It isn't entirely accurate, but it will give you a good estimate.

Your desired compression ratio depends on what kind of gas you have available and how good the tuning is.

 

Just wondering in my case,is it possible to put stage 2 cams (for example skunk 2 stage 2)? Cause all my internal is stock. Also I have a question,I'm thinking to buy AEM UEGO air/fuel ratio and VAFC2 (cause to hondata or other similar,here) to fine tune it.Do this will make a noticeable different or the stock ECU just good enough? Thanks.

 

I meant no one sell Hondata or other similarity here in my country. And I use 95 octan.
