this dude here has the same set up as u just wrote up. In a daily stock ek hatch, with full interior on 25" slicks ran 12.9 best time. hp was 200 i believe. My tuner tuned the car and theres videos of it on you tube.

but i believe he has aftermarket pistons 84mm like 11.5 or 12.1

wow thats awesome. im doing a similar build in my 95 eg. b20 block, ls crank and rods, b20 11.5:1 pistons, blox stage2 cams, omni power springs and retainers with stock valves in a b17 vtec head with a skunk2 manifold, blox 70mm TB, and a hytech replica header. pls alert me if something doesnt look right as i am a b series noob lol. ive been k series and im going backwards in the honda line lol.

there is a guy here that ran 12s on a DD STOCK internally b20vtec in an EG. He had a JDM ITR header, victorX mani, and tuned it made 180ish to the wheels.

try getting it tuned to figure out how much power it will make, untill then keep guessing.

judging by the many stock b20b vtec i have seen i say around the 160-175 whp mark if it was the b20z maybe a lil more but like turbociv said get it tuned because wont know til you get that doe it can make 140 whp you never really know but the average i have seen has been 160-175ish with a good tune

kris5597

So the main way to make great power b20 vtec is up the compression?

negusjuda

dont just run out and get the highest compression piston you can find like so many people run out and do. compression is a very small factor in making power. the right matching parts is more important then compression. you wanna match compression with cam selection along with the fuel you plan on using. if its a daily driver running on pump gas 11.5:1 compression max is highly recomended for cars running pump gas. although some run higher compression on pump gas it is actually pointless. the higher the compression the more ignition and cam timing will have to be retarded to run safley on pump gas which accounts for a loss in hp. so typically weither you run 11.5:1 or 12.5:1 you will make the same power with the same part selection. its only a 3-4 hp diffrence per point of compression, meaning if a motor with 11:1 compression makes 200 hp the same motor with say 13:1 compression and same exact parts and tune will probably make 206-208 hp and will have no room for error. in some cases the 11:1 motor will make more power due to the ability to run agressive advanced ignition and cam timing while the 13:1 compression motor cant

kris5597

O ok I understand. My build will be a DD an track car. Just something to haves blast in honestly. So I'll prob just rock 11.0-11.5:1 compression then. My goal is 200whp b20 vtec. I hope the blox cams will allow for that. Running ls rods and crank. Will there be any benefit?

ALLMOT0REJ1

not bad bump

kris5597

Are the girdles a must?

negusjuda

12.5:1 with pro 2 isnt bad thats a pretty good combo i would run 93 octane or e85 though

ALLMOT0REJ1

bumppp

kris5597

How are blox cams? And will they make decent power til I can buy s2s?

turbociv910

do that build you just listed, that should be strong if setup properly

DDTECH

No.

Garrett

saturday I will tune on with almost the same setup as you, against the header

I will post the dynosheet here if you want

gixxerboy750

yes they are to big, he just took them on off his boys turboed car for haha's n he ran a 12.9 with them instead of the 23" slicks. He came out the whole with a very good 60' and didn't spin at all. It all comes down to how good you can drive, gearing and suspension. He hit 200hp tuned on chrome with all that u listed up there.

ALLMOT0REJ1

bumppppp

ALLMOT0REJ1

Btw you said there was vids on youtube of the car what do I search under

gixxerboy750

yea 23" slicks are perfect for a stock to mild all motor setup. H2B and K's we need 24" theres just alouta low end torque, but ull be good i have the same type r tranny with lsd and it hooks real good off the line.

gixxerboy750

his is the purple car.
yup here this is when he did a 13.0 and then after that he did a 12.9 vs a FULLY BUILT RACE GAS ITB b20v. Justgoes to show u its not what u have just if you can drive it.

gixxerboy750

and thats with stock suspension lmao, hes a really good driver though. My tuner tuned all these cars and that 10.4 lsv turbo one daily driven. Ull do good with your set up. Just practice launchin it good.
