gold top vs. black top b20's

[thegreatdane]

shit, only 105whp.. that's about 125hp at the engine. Not impressive. And that's a blacktop, right?

Until I see proof otherwise I dont believe that any JDM gold or blacktop has ever made 160hp stock. I'm even starting to think that the edm B20A1/2's are running stronger than the JDM ones. But 125hp seems a bit too discrete for a B20a.

I hope to dyno a stock b20a sometime but with obd1+crome tuning to see how much it's actually capable of putting out stock.

hauntd was that your B20A?

[AccordB20A]

i bet your b20a5 prelude extractors took away 25 of your whp
i have a good ish engine currently that has low kms minus the high KMs head on it wishi could have it dynoed in its stock form as it is now

i beat a b16a integra by a car length back in the day with a stock exhaust and cai. me gf and subs in the car. that was with a stock as a rock looked after b20a that has 168000kms from a parts car that i had that was rusted out. that engine was fast. all the ones i have had since are slower i recon

see this is it with my b18 gearbox http://nz.youtube.com/watch?v=a4xw1t4mGig looks fast one i started nailing it after pulling out of the intersection slowly

yeah that is my black top
and yes i was depressed
mind you i held off full throttle out of sympathy for an old motor in needof servicing and wasnt sure of the cond of cam belt
am not sure if something was wrong as it stopped as soon as i stepped on the clutch at the end of the run.
the thing wouldnt start on its own and needed a jump start
would a low voltage cause hp loss due to ecu and sensors not getting 13.7 volts?
the batt was completely fucked
dropped to 4 volts for cranking test

Yup, I'm sure they made less too. No wonder Honda changed the power output on the blacktops.

Mine did 145 at the wheels on a stock exhaust (1.5inch) and stock ECU :D

I really need a better exhaust!

Yea and some proper engine management! :) hehe are you still using a stock exhaust, well it's effective if you want to reduce noise I guess but other than that :)
Btw are you running stock fuel pressure or did you turn that up a bit to compensate for the stock ecu?

[carotman]

Nope, I'm running the stock management (PH3 ROM) with stock fuel pressure.
The sparkplugs do not seem to get too hot so it's not running that lean I guess. This is probably because I'm using the stock exhaust and it can't get all the gasses out at higher RPM.

I really need to take care of that!

[Hauntd ca3]

thats pretty good power!
even tho mines a jdm import, i have been told that the ones with the open haedlights were destined for the edm which were detuned a bit werent they?
if not,what a downer
the 285,000 km wont help to much
must bring a comp tester home and check the motor out.
am planning on doing another dyno run before i build the next motor
so i might give it the full tune up and service and see how she fairs then
duz anyone know if f22b rods fit the b20a?
and if they are stronger
have one at work with bent valves i mite scavenge off if things fit

not running lean and running the most power effective A/F ratio are 2 very different scenarios
You could try hooking a wideband on it to see where it's at. It should be at around 13:1 a/f at WOT. There's a lot of power to get between 14.7:1 and 13:1.

yes the edm ones were listed at 137hp (ex. B20A8) but makes ~145hp on the dyno.

If those rods are same as H23 rods they should fit.

[Nafs Asdf]

Wikipedia's got B20A1 at 137 hp, A2 at 142 hp and A8 at 133 hp.

[A18A]

someone give me $6000 so i can dyno my car!!

[MessyHonda]

someone give me $6000 so i can dyno my car!!

come over here they dyno cars for like 80 bucks an hr...or just send me your engine and il dyno it for you

[Hauntd ca3]

thnk he means 6k to install and tune an after market ecu for his itbs

[thegreatdane]

Wikipedia's got B20A1 at 137 hp, A2 at 142 hp and A8 at 133 hp.

the wikipedia is not correct then.

[Hauntd ca3]

[QUOTE=thegreatdane;874406]yes the edm ones were listed at 137hp (ex. B20A8) but makes ~145hp on the dyno.

well if they make 145 at the flywheel 115/120 at the wheels would be bout right for a new motor then right?
even tho i have the headers and full exhaust 105hp doesnt seem to far off for a motor with 285k on the clock
mind you the fact that the dyno was a fiftyyear old water brake that is always breaking down
wouldnt help to much

[2oodoor]

well at least it is good to know a B20A will make it to 285KK, that is a lot more than I see D15, B16 going. (standing aside from flames)
and a lot more than I see B20A5's making it, but then I have not been looking too hard either.

[Hauntd ca3]

just noticed today that the engine serial number is just b20a and the the actual serial number under it.
thort they were meant to have the model number after the b20a part
eg b20a2 or b20a8
what does this mean?

[A18A]

nah all jdm models are just b20a, its the europeans that got the b20a1/2/8s

[Hauntd ca3]

ah ha!
that clears that up
cheers dude

[oscwrestler]

i pulled a gold valve cover off of an accord ant the jy. dont tell me i missed a huge find...

[carotman]

No, some A20A (BS1) had a gold valve cover.

[AccordB20A]

heres what everyone been looking for. I foudn it im the man, the answer to all goldtop and blacktop questions::::



as opposed to the gold top's....

[snoopyloopy]

mmhmmm

[A18A]

my car gets more than 12.4km/l woot
