This is stock jdm b20b bottom with b17 head. short ram intake, ported tb, dented dc 4-2-1 header, greddy sp exhaust, high flow cat, msd 7al-2.



red is with stock cat, auto pr3. Blue is with "high flow" cat and mugen pr3.

Im liking those numbers...esp that torque figure.

 

what kinda pistons?

 

wow so that gain is only from swithing to the Mugen PR3 ecu? would it be better to get that ecu or for the same money get hondata s200 for the PR3 ecu?

just curiouse.

 

Nice numbers for stock b20

stock b20b pistons. according to c-speedracing.com, it's approximately 9.3:1 compression.

As far as the comment on mugen vs hondata, I think the power gain came evenly from straight pipe and the pr3 ecu. This mugen program does a good job, but the graphs are still pretty rough and there are dips in the curve. If I had hondata, those dips will be gone and graph will be smooth. And also where as mugen program is fixed program, with hondata you could optimize power with your custom setup.

Not bad

 

I need to get a header. There's still a dip in my dyno.

that's close to my set up, u made me smile

 

does anyone have a dyno of a real stock b20? cause i'd like to see how that looks......cause i dont' have a b20 vtec.....only a b20.

$600 that you spend for a vtec head will yield a lot more power than $600 you'll spend modding a non-vtec b20.

well geuss what i don't have money........to mod anyways.....i'm 17 and broke as hell!!! i also have an automatic....so i'd also have to swap trannies and i'd have to get an si/itr tranny cause i'm not goin to waste my money on an ls or gsr tranny. or i can get an ecu from a jdm si vtec integra.....but i've not found one for under $1000....anyone have a stock b20 dyno? like one not on a crv anyways! thanks

why not??same motor..diff car aint gonna boost its #'s if its the exact same thing..

 

well it's a differant intake manifold. and i've heard from a few people that the ls im flows better and u use an ls im if u drop a b20 into any car other than a crv

 

weaksauce

 

My Buddy is building a B20, predicting 300+whp and about 170+tq. Im not impressed by those #'s, my GSR has more power but a lil less TQ

All motor? good luck. bet your gsr has more mods than my b20.

bet it does too, ... but I bet yours cost more to build And the other B20, my buddy runs his own performance shop, builds and Tunes his own motors and works in conjunction with RPMNYC. Of course, his wont be stock putting out those #'s, but that's his "prediction", not reality. Frankly, I think it will be close, and the fact its going in a mint CRX will make it deadly!!!

 

nobody cares about pure race motors that cost 10-20k to build man and cant run on pump..go brag on some other thread

 

Not bad at all.

 

You'd greatly benefit from a header, full 2.5" header-back exhaust piping, and some fuel tuning.

You should be hitting 180 whp and 140 tq easy with that setup.

 

torque looks good

Actually, it is going to run on pump gas.. How am I braggin? Im just sayin for a B20, that dosent impress me, ITR's make those #'s stock. B20 in general cant be a cheap motor to build. I could be wrong though.
