Ok I'm building a b20 vtec and wanna know the right path to take to reah my goal of 220 whp here's what I have

B20b block

11:1 rs pistons

Eagle rods, arp rod bolts

Micro polished crank and all balanced

Type r pump oil/water etc

Bisi headers

2.5 manderail exhaust

B16 head with skunk 2 springs and retainers

Buddyclub stage 3 cams

Lmk what you think

Assuming you are getting a fresh hone and resurface, everything sounds good. But what tuning setup are you going to use? I.E. Hondata, AEM EMS, etc. And what intake manifold/throttle body? Any port/polish? Have you considered upgrading your ignition too?

Overall, it seems like you got your hands on a pretty secure platform as far as the engine assembly goes. What kind of vehicle is this motor going into?

Hmm prob hondata.. As far as intake manni possibly the performer x? And I have a skunk 70 mm tb but need to go smaller I recently switched from a full turbo motor 500hp build to a little na setup and this will be in a ef... With all suspension traction bar etc... No port n polish either I know it recommended but idk. Also I realized I have Buddyclub stage 4's not 3

everything sounds good... I would go with BC Spec IV though or a pro 1...

and no on the performer x... a skunk2 will outperform it in a 2.0l motor

spoon93

Oh ok I thought the performer was best thanks... And wat size tb u reccomend and I have the Bc spec 4's

I ran the same setup as what you're described (except stock rods w/arps). I used BCIV's, hytech rep header, 68mm tb, 440's, blox IM, hondata s300, 3" v.stack, and made 215 whp.

I think your goal is feasible.

I have seen couple of dyno graphs of B20 similar to this with BC3+ coming in at 215WHP. I have B18C1 with BC3+ and my best is 193WHP.
Based on these observations I would say that 210-220 WHP with this type of setup is possible.
For DD reliability BC3+ is hard to beat for balance of everything.

If reliability is not the primary driver but power is, BC 4 or pro2s (and a few other) will be a better choice and probably put you slightly over your goal without much hassle where BC3+ will be pushed to get there and might come in at few WHP less.

Buddy club 4s need more compression than 11.5 to make 220whp, but it can be done. Also, keep your TB, it works fine with NA cars as long as the air intake is also 3"

Ok thanks guys and shodan wat intake manni do u think is a good choice?

jdmcivic2fast

ported Type Rrrrrr

everything is fine but get the head ported and polished and for TB 70mm is great or if u can go 74mm more air the more fuel the more power you can make.skunk2 intake will be the best for you.i would use pro 2 cams from skunk2.

spoon93

Hmm a lot o mixed answers here lol hey shodan so I need mor e comp for these cams? But it may be possible to reach 220? What can u recommend me to do ur opinion? Etc thanks guys

I'm a Ported ITR & SKunk2 IM guy, but the Performer X does well also.
Between Skunk2/Performer X IMHO you're kinda splitting hairs. For 220whp, either one will work.

The thing to remember too, is what Throttle Body you plan to use. I myself am switching from a Ported ITR throttlebody to a Skunk2 Alpha 70mm on my wife's Toda Civic.

spoon93

Ok I'll prob run the skunk im and my 70 m tbwat about cams should I downgrade a little?

Do a little more reading on header testing. The Bisi header may not be the right one for your application

spoon93

they should do ok

A2C0U0R0A0

Feed me knowledge yum.

spoon93

I also double checked on the pistons and there rated at 11:7 or 12:0 depending on which head I use and I'm running a b16 head wich I beleive has 0.10 milled from it and an oem golden eagle head gasket now that I think hopefully I'll be ok with p to v clearance

spoon93

So possible I can be closed to 12: compression

spoon93

What's ur thoughts on this????

crazydominicanman

Your compression, overall combination of parts should render you 220 whp. I wouldn't run the bisimoto v2 header replica on that setup though, are you looking to keep a/c? I see your worried on P2V clearance, claying the motor would give you piece of mind. Can't really skimp on these frank builds when it comes to wanting a reliable, healthy motor...

spoon93

No ac.. What's wrong with the headers

PinkBatman

Just for reference here is my setup

B16 Ported Head
70mm throttle
Victor X intake
Blox B Cams
Bisi V2 Prototype header

B20B Bottom
Balanced and polished crank
ACL Standard Bearing Set
Arias 85mm 11:1 Compression Pistons and Rings
Eagle LS/B20 H Beam Connecting Rods
Golden Eagle MFG Billet Aluminum Main Girdle

91 octane street tune
226whp | 153tq

Hope that helps.
