I'm building my B20vtec and it's going in next month. Here's my setup, can you guys predict what kind of output this will dish out?

B20 block
B16a head
GSR tranny
11.1:1 CR (85mm JE pistons)
CTR cams
ITR ECU
Skunk2 cam gears
Skunk2 intake manifold
64mm TB
8.8 lbs FW
4-1 header w/2.5 collector
290cc injectors

Just wondering, thanks guys.

 

Not to be an *** but all motors are diffrent and why dont you build it and then Dyno it and tell us the number...it doesnt look like its going to be much....

maybe 190 whp

 

Well I've seen the B18C5 and LSvtec with the same setup and they dynoed around 175-180whp. And then I've seen B20vtec setups with more aggressive cams and higher CR (12.5-13:1 CR) dynoed at 217-227whp. I haven't seen a dyno chart similar to my setup, so that's why I'm asking you guys.

 

I'm curious, why do you want to use the ITR ecu?

 

Well, I bought this ecu before I even bought anything for the motor (good deal). Simply because it's OBDII and has better air/fuel maps than the GSR.

 

You'd be further ahead selling the P73 ECU and getting an OBDI and adaptor harness. Even if you go with a one size fits all chip rather than the far more elegant and effective Hondata fix I think you'll get more for your $$$s.

There are several dyno charts of CR/Vtec setups at importreview.com.

 

hmmm, your set up seems to be missing adequate fuel control for 200whp+

using VAFC or getting Hondata?

t..

 

BTW, has anybody seen the new Sport Compact Car (I think). It has 3 crvtec civics. One of them dynoed over 200 with only 10.5:1 comp. What is up with that?

I have almost the same setup but with full skunk valvetrain and skunk stage 2 cams with hondata s200 with rods too and got 202 WHP. Post up what you dyno...I'd be interested in knowing...

 

I heard / read about a few setups making great whp on only 11.5:1. Just shows you don't need crazy high compression for good power.
