A20a4!!!!!

[89ACCORDVTECH]

A while back i posted a thread that asked anybody and everybody if they knew where i can find an A20A3 for my rcently purchased 89LXI Coupe. No one left me not even a hint where i could get one or where to look. I went to a website called LKQ.COM. So i ordered my engine from them and when it got here today i looked to make sure it was the right one and not some shitty motor and it said A20A4. I looked up the specs and the motor is EDM 125 horsepower and 170lb/ft of torque. So thanks to all those who did not help me out, i ended up with a way better engine that i didnt even know exsisted :lol: :bowrofl:

[Busted_Blue]

how is it possible to have 125 and 170lbs of torque? Not even the b20 has that much torque...

I suspect the torque numbers should be anyhwere from 90-120lbs max.

[89ACCORDVTECH]

Okay i exagerated a little bit it has 166lb/ft of torque. Check the specs be 4 u open you decide to correct me buddy.

[89ACCORDVTECH]

B20s are shit anyway unless u build it TYPE "R"

[HondaBoy]

how many miles did the engine have on it? interesting to find an A4. i thought the torque was more like 122.4 tq. and 122 hp. this is found true by Paul Aerodeck86. and its 166 nm, not tq. at least you got that right, sorta. one more thing, is it just being ironic, but Vtech makes electronics, Vtec are the dual purpose cam timing controled heads. i dunno. anyway, be cool dude. any idea on what year and model the engine came from. prelude or accord? and was it from canada?

[AccordEpicenter]

it shouldnt really matter, the internals/manifolds are very close etc... so id say for FI 122hp, sei 127... simple enough

[89ACCORDVTECH]

89ACCORDVTEC-H-SERIES is what it is supposed to say but it did not fit as a user name . I've been getting lashed for that shit ever sine i joined this site.I dont know what year or model it came out of but i know th car had caught fire due to the fact that there is a little bit of ash in the throttle body, the intake manifold is a little charred. All the wires and everything else are fine though.I'm going to do some double checking on the actual power on this engine and dyno it with the all the ported and polished B18 intake manifold,gsr injectors,open loop motorsports mild cam, ported and polished head,custom header,type r fuel pump,msd ignition, etc to much to list i will keep u guys updated "PEACE"

[89ACCORDVTECH]

Drunk As ?

[89ACCORDVTECH]

OH WELL! All l know is that igot a A20A4 and u dont(.)

[thegreatdane]

It's 122hp, not 125... The torque is about 125lbs/ft.

[89ACCORDVTECH]

Emissions? I can get anything i want to pass smog but it doesnt mean the engine has to have emissions controls , all you gotta have it dollas in the pocket.

[HondaBoy]

do they even do real emissions checks where you are? like in your area. i know your in california though, so they supposed to. as for me, i've become friends with a few different shops that do inspections. only thing they want is the car to be safe and road worthy, otherwise they dont check guys w/o a cat or other stuff. i'm going to have to make sure next time i get my car inspected, the person i know is at the shop i go to.

[Micah 89LXi]

thats whats great about living in podunk wv where no one gives a shit whats on or off the car

[SteveDX89]

OH WELL! All l know is that igot a A20A4 and u dont(.)

Wow, you have the same thing as A20A3 but less emissions stuff. That's the only difference between the 2.

[thegreatdane]

The compression ratio is also different...

[SteveDX89]

The compression ratio is also different...

What is the compression ratio of an A20A4?

[shepherd79]

compression ratio is the same on both engines. if euro had higher ratio it would have more power.
they do say euro A20A4 has better cam, but since no one has tried to compare them, we can't say for sure it is better than US EFI version or not.

[AccordEpicenter]

who knows, i dont think it could be that much more radical. If you want a better cam get an SEI cam or somthing even better than that.

[SteveDX89]

The SE-i motor is exactly the same as LX-i motors.

[AccordEpicenter]

sei has 5 extra hp

[Cheeseburger]

to bad i didnt see your thread on time. i found a place in the valley that sells honda engines and trannys

[ICEMAN707]

LKQ is the best. It is based here in FL. There's 5 locations: Tampa, Clearwater, St. Pete, Bradenton, and Orlando. Cleanest salvage yard I've ever seen. No spills on the ground. Cars are all 2 feet off the ground, categorized by manufacturer, and alphabetized. Parts are really cheap. Complete engines for $200 ($100 for block and head only), $45 for all transmissions, etc. Unfortunately B-series and other sought after engines go there very quickly at those prices. You have to have connections inside to get first dibs. Good thing my friend has a friend that works there. :cool:

[b8er]

i did a basic motor swap ( just the block/head and internals ) to the a20a4 and to be completey honest there is no difference between the a20a3 and the a20a4, i dont know where this guy gets off thinking hes better then everybody else, from what i know the a20a4 has 122hp and 125foot pounds. and yes its true that there isnt any emmisions stuff., iv rode in both a20a3 and a a20a4 car and i have felt no difference.

[A20A1]

sei has 5 extra hp

Maybe because of the exhaust?

Did you switch to the A4 ECU?

.
..

[A20A1]

AFAIK, the only thing differeint in the SEi exhaust is a dual outlet.

I don't think that'd make 5hp. Maybe in riceland. =\

I was just asking... :crying:

[88eyeguy]

Wait a minute...why does your profile say 89 Accord h23 w/ h22 head swap? if you have an h23 in your accord why in the crap would you even think about the a20??? if i'm off, then please clarify.

[SteveDX89]

sei has 5 extra hp

What prestiguous source did you get that info from? Last time I looked through my Chilton which lists every motor available in Accords and Preludes from 84-95, there was no 127 hp A20A3.

[2drSE-i]

in my se-i owners manual it says 122....sry buddy

[b8er]

yea i did switch the ecu, i figured i would have to since there wasnt any emitions stuff.

i dont think there would be any way that dual tips would give you an extra 5hp, lol

[thegreatdane]

What is the compression ratio of an A20A4?

9,4:1 and the compression ratio of an A20A3 is 8,8:1. At least the A20A3's here in europe are.

[shepherd79]

the A20A3 has 9.3:1 here in the US. so it is not that big of a deal.

[Legend_master]

B20s are shit anyway unless u build it TYPE "R"


Man you sound like a little kid with some of your statements. To be correct they are talking about a different B20, the one you are talking about comes out of the new CRV's and the one they are talking about comes out of the 3rd generation EDM Si accords. Also the b20 is not a piece of shit if built right, compared to the a20a4 of yours it would dominate all around (quiality, perfromance gains, aftermarket support). They have produced some very high numbers out of those motors without putting Vtec heads or raising the compression. They are very turbo friendly motors and very well built. I think you should read what you are about to post before you post it, becuase every statment you have made in this thread was wrong.

P.S. I am not bashing the a20 at all just helping with a little info, because for a 19 year old motor they do one hell of a job.

[A20A1]

In Europe or at least in Australia the SI badge is the SOHC A20 the 2.0I-16 is the DOHC B20

[Legend_master]

I think I said it right, the EDM Si only comes with a b20 Or is there a a20 powered EDM Si also?

[w00tw00t111]

It's pretty much the same in houston. My dad has had two cracked headlights with book tape over them. Depending on the shop though. My Dad's mechanic took it over to his friend that has an inspection shop. The inspection cost just under $100. They are normally about $40. Cash always helps persuade ;)

Unless you life in Europe I think it would have been just as beneficial to have bought a a20a1 and build it up. That's just my .02 cents and feel free to correct me. In regards to the B20 comment even stock from the CRV. Just think about it. It's got to have power but even more so torque to move that SUV. So just using common since if you were to put that in a lighter car it should accelerate quite well. But once again all I was using was common sense not any facts or figures so correct me all you want :) .

[mouchyn]

126 HP and 133 tq? that's pretty laughable for a late 90's 2.0L engine. the craptastic b20a in my 3G prelude made more power and torque than that!

the b20b needs some SERIOUS work to make it a worthy swap.

just a side note getting a little off track, some of the students here at the wyotech campus sacramento put the CRV B20 WITH the whole AWD system..... not that is hott shit. a 2300 lbs car launching with AWD drive!!

Did they put it into a civic? becuase that would just be clean as hell. Do you know what they did for axles and rear hubs.

[MarioBurke]

yep blue civic SI, bronze rims. used the entire drive train from the CRV, shorted the drive shaft, made new mount brackets for the supsension both front and rear because it is a bit wider. i think some how they got away with using the hub that was already on the SI

that is so Pimp, I did see an integra once that had that done. It ended up not working to well so the made it into a RWD car and started drifiting it. One thing I was curiose about is if it was a Five speed, because the CRV never came in a 5-speed or at least the AWD dident. Sorry to get so off topic :ugh: .

[MarioBurke]

actually that part I am not sure about? I'll have to find out more. they took the car out of the shop though cause one of the teachers was fucked up and put fat scratch in the hood and then denied it and wouldnt pay to fix it

[P|eszczoH]

I think I said it right, the EDM Si only comes with a b20 Or is there a a20 powered EDM Si also?

There is no SI in Europe.
B20 were only put into sedans with 2,0i-16 sig on it. with 133 HP or 137 HP
all of the others were A20ies.

[smufguy]

8.8:1 = 86-87 efi
9.3:1 = 88-89 efi.
9.1:1 = 86-89 carbs.

Sorry to barge into this thread and state the obvious. but seems like this is the second thread thats being fugged up in a technical/performance section.

Eurpoean cars (some of them) did not have Oxygen sensors and ran different emission system with a different ecu and regardless of whatever, USDM 86-87 efis ran single Oxygen sensors and 88-89 ran with two Oxygen sensors and had different ECUs for those two year periods even tho they belong to the same generation.

[P|eszczoH]

Yeah, you Are right

in Europe it was like

No Oxygen Sensor A20A2 and A20A4 olso B20A2
With Oxygen sensor A20A1 and A20A3 olso B20A8 - all of those 3 had only one oxygen sensor.

engine code/ compresion ratio/ HP
A20A1 / 9,1:1 / 102
A20A2 / 9,2:1 / 106
A20A3 / 8,8:1 / 115
A20A4 / 9,4:1 / 122 - also said to ran high octan fuel!!

A20A2 and A20A4 had double down pipe instead of single one used in A20A1 nad A20A3. I'm preety sure those ran different ECU too.

just a side note getting a little off track, some of the students here at the wyotech campus sacramento put the CRV B20 WITH the whole AWD system..... not that is hott shit. a 2300 lbs car launching with AWD drive!!
And that is why I want to go to Wyotech!

Yeah I saw that on a drifting show. He did much better then a fwd integra would IMO. Seemed like it would be quite awesome until I heared about the CRV AWD that is just amazing! I would kill for that. I don't know if many of you US guys realize it but in 5 to 9 years we won't have to go through an inspection b/c our cars will be over 25 years old. That'll be pretty exciting!

[buds302]

thats whats great about living in podunk wv where no one gives a shit whats on or off the car


i hear ya there!!!! i can put anything on my car and itll still pass inspection. i could gut the cat but as long as the shell is there itll still pass. it dont matter!!!


OH WELL! All l know is that igot a A20A4 and u dont(.)

see you keep thinkin you got better shit and you watch some kid in a corrola is gonna whip ur ass in a race and then youll be thinkin "man my car is shit!" then youll be cussin thepeople who sold you the motor cause its a piece of shit

[McNick]

62se-310 at Paul's site have a description of cam shafts on page 2-5.
Inj. KX has a delay of one intake valve while opening. KG has no delay.
KX seems to be A3. KG means A4.
The reason of delay is better mixture mixing because of screwing of mixture flow.
just my 0.02 hrivna.

[POS carb]

either way you can just swap the a3 manifolds onto it will retain all stock emmissions

nice a20a4, if the compression ratio is lower on that engine congrats you have a cheap $/hp mod waiting under your cylinder head
