Want to build a b20vtec whats the most power i can get out of it

not out of a B Series unless you want to spend $20000 and it wont be reliable.

Look 300whp IS RETARDED POWER and is a race motor that lasts a few thousand miles if that.

Something more realistic is 200-220whp but even 220+ will cost a lot of money. Youre talking about rods, pistons , cams, OEM parts, springs, ret, headwork, intake manny, tb, injectors, ecu, tuning, header, list goes on and on.

Seems like you have no idea what to do, so heres my advice.........put your b16 head on your b20block, put it in your car. Put a JRSC on your car with 5 psi and make 250whp, reliably, and destroy most cars on the street. The JRSC will run you $1000-1200

or if you want to stay NA figure out a REALISTIC BUDGET and we can go from there

[civicnick]

go H... haha

[DC2NR]

Hard enough to get to 200whp with money being an issue. Gl with 300. Take Mr.kidd's advice.

[SPOOLIN]

theres only been maybe 5 b series to reach 300whp ever. And i promise they were not on the street.

[WAT TURBO?]

why would you go NA with such a small displacement motor? If money is not an issue, why not build the bottom end, sleeve the block and run a BIG Precision Billet wheel turbo and make 600+whp?

[BABY J]

Don't horsepower shop. Shop for reliability. These are just the BASICS - and yes since you're hunting big power I say that sleeves are part of the basics.

* sleeves
* forged internals (rods/pistons) - Scat makes the lightest rods (out of the box) for a B series. And you want around 12:0 CR (any more and we get into splitting the flame front which is beyond the scope of this thread)
*gaskets/bearings
* bolts ons (IM, KiddRacing header, flywheel, exhaust)

That is just "basic" stuff. What's gonna set you apart from the rest is the top end. If you don't want a $1000 - $2000 head then no point in doing none of the above really. The head is what brings home the bacon.

http://www.stewartengines.com/ or www.team4piston.com is a good place to start.

Build this motor on paper - call around, get prices for assembly (MSS Racing, MSP, etc) and parts. If your pockets still don't get nervous go for it. You don't have to make 300hp to outrun a lot of local FR guys. Good luck.

you dont need a BIG precision billet wheel turbo, just the Billet 62mm would do the trick.

300 WHP N/A is insane, you will be doing burnouts everywhere trying to get the car to move

[SPOOLIN]

not if you redistribute weight.

very true!!

like vteckidd said, a 300whp ls/vtec if rarely i mean rarely seen on the streets, that engine is not made for that much power, if you want to be fast and do it cheap the best way will be turbo but if you want to stay n/a you are going to have to follow the saying ( you got to pay to play) and is not wort it but it will be good to see somenthing that different, the just a 170-190 ls/vtec or just save up a lot and get somenthing different..

[RBS]

b20 block, RS machine pistons, ARP goodies, PORTED b16 head and tuner3 cams. this setup has been proven to produce around 2-220WHP guaranteed and is quite lovely on the street while being within a reasonable budget.

[SPOOLIN]

its not that the engine cant handle it, its just that with that power on that type engine, youll need atleast e85 to drive it on the streets....and the cams will be obnoxious, the driveability will be qwerky, and the noise would be terrible LOL

thanks for that spoolin here to learn.

[clumsy_smurf]

i had a b20v in my eg hatch. it had a ported and polished gsr head, stock pistons, shot peened rods, eagle crank, arp everything, etc...and i made right around 210 hp. which was plenty for me.

too much $, not enough power.....

[TeamFX_K24a4]

i agree... never said it was cheap- exactly what is enough ?

[BABY J]

Enough? Enough for that build is Pro1s - Pro2s at the MOST for starters.

a mildly built LS w/ a 75 shot would've killed you...... and you would've spent thousands more (according to your $5,000 price)..... thats why I say too much $ and not enough power. not trying to be an ass, just saying.

Ehh $5000 is about right. That's not a cheap motor to build. Stock
Port prob hurts. What header?

That's still good power in GA

[DarKStaR]

stock port killed those cams. A buddy of mine made 216 with blox b's with similar setup on stock port head and tb

[TeamFX_K24a4]

yes stock port head is killing those pro3s- is running on kidd rmf... professionaly ported head would be my next step- to jdm94coupe- i can spray too- this build is strickly NA no power adders...
mike its johnny-thnks for the advice on the build :).. darkstar... which dyno..and who tuned it...

[Vteckidd]

truth is even on a stock ported head 217 (i assume this was Mainstreams dyno?) is still really good power. Theres very few people who crack 210 no matter what. Personally i would port the head and retune. It doesnt even have to be an aggressive port, just a street port from someone like Portflow or Max CFM will do. $500-800 tops.

should be in the upper 220s , low 230s if the head is truly what is holding it back

[TeamFX_K24a4]

thanks mike- scotty tuned it- i dont see what else could be holding me back- properly degreed in cams, rc injectors, walbro 255, 3inch exhaust-

[Vteckidd]

Yeah head is prob it.

[DarKStaR]

it was on mainstreams dyno and scotty tuned..

[h22 jones]

You should get my dad to port and polish your head for you. He does a realy good job for a fair price (700.00). Im sure you want be disapointed ask scottie(at mainstream) he has seen the dyno results they dont lie.

[Theycall_Metue]

im thinking the exhaust is a little too big

[h22 jones]

i dont beleive he needs 3 inch exhaust and it may be hurting his tourqe some but i doubt his hp. I dont think that is the problem .

[h22 jones]

so he can be slow?
j/k Nick

i like being slow lol. So when you going to get that beast back on the road ? I know you are not still waiting on rockers lol. What did you do decide to go with some exspensive roller rocker setup? I enjoy seeing the car run dont retire it just yet.

[Vteckidd]

I forget jones dad does porting. Doh! Yeah let his dad do it

[EmminoDaGreat]

Tell dad I need a prototype F23 head :)

[h22 jones]

Hmm i actually i have a good h23 head sitting here off the motor i that i pulled my crank out of. Ill see what he says.

I just now saw this. I was wondering what you were talking about why didn't I reply. lol.

[h22 jones]

Yea , Yea lol. Sneaky,sneaky i would have put a 75 shot under the seat had i none lmao. Nice to meet you man nice times hope it gets better . It actually gives me a reason to put my shit together . Plus nyc guys car im sure its in the elevens to should be a good year . I already got a h2b setup i built for a buddy of mine done that should put down around 280hp but its in a ek so not sure what it will do . Im trying for 300hp but i still want to be able to drive it on the street so we will see man . If not ill just do it like yours not pro but nice and light lol.

[ek forever]

too much $, not enough power.....

His problem there appears to be lack of compression. Why would you go through all that effort and not bump the compression?

[Jdm94Coupe]

That's not his only problem.....makes no sense why you would buy pro3 cams with the stock port head.

[BABY J]

This. This was the 1st thing I said - no midrange, and really not enough head to benefit from the rediculous cams.
