i have the basic 2bbl A20A. it definately could use some upgrades. i am thinking on going with a bullfrog cylinder head, camshaft, and sprockets. then for the other internals like pistons, rods and crank shaft i want to go with raceeng.com to make me some of that stuff. does anyone know if someone else makes ready made parts for this engine because i will have to send in sample parts of what is listed above to these two company

start with the carb, then exhaust, then cam.

A20A1

hmm some people on the board would not recomend BULLFROG.
even though it is a good package... if the quality of work is poor your better off doing each of those mods seperately.

Bulffrog stuff isn't ready made... You'll have to send in your CORE... Core being the head and cam thats from your car. If you want you could find a spare head and cam in the junk yard... try and pull a set from the same year, fuel type (carb or EFI), and transmission type.

just get weber and start working from there. weber gives you most performance for a buck.

how much performance does a weber give you?? i was thinking about working my car up for a good old tank of zex, seems like more bang for the buck then the weber carb.

shepherd79
09-03-2002, 10:55 AM
yeah, but offten are you gonna hit zex. are you gonna run on it or you will use it one in a while?
lets see, A20A1 has weber and he has auto, and he said he can burn tires with it, or at least used to. how imagine what it can do with 5 speed?

what type of weber carb should i search then?? (ive got the f20A2 carb version)

Experimental_Honda
09-03-2002, 12:14 PM
yeah i have a 5 speed, i was only gonna use the zex in high speed races and maybe pop it once in a while if i wanna fuck with someone in a much faster car, i was gonna pop 45 shots. i took out the pan style air filter and custom fitted short ram intake, im guessing it will work since a20a1 did the same.

shepherd79
09-03-2002, 04:36 PM
hey dutchaccord, i am not sure what kind carb you have, but before you start searching for the carb, try to find the adapter for it.
can you post the pictures if your carb?
have you ever took it out?

dutchaccord
09-03-2002, 11:48 PM
never took it out.....

and if ive found the carb's (pref 4) i DIY me a intake headder.

k so u say bullfrog is no good? and wat did u mean that its has poor quality work? do u mean that it is not durable. i just want something that will give me some noticable power increase. they told me that the cylinder head will give me around 58hp and cam 26hp. maybe they are bull shitting. i think the other internals by raceeng.com will be quality work cuz they do everything to perfect or almost perfect specs. that is wat ive herd. ive seen dragracing crx's with stuff from bullfrog. stock engine and all. so i dont know. i need an opinion form someone that has had parts from bullfrog. please tell me wat u thank. i dont want to make any costly mistakes.

Well, our heads are hard to mill a whole lot...valve clearances and such. Cams...well, you don't want this to go bad.

the ones in the later part of 89 in japan looked exactly like our 4th gen in the US. so it might be that too. who knows.

I would have to see your car and or a carburetor gasket... preferably the one that sits between the intake manifold and the carburetor. I'm curious to see what your intake runners look like?

Do the japanese models have better engines in them and better parts etc???????

I can easily get my hands on that stuff if i want to.....
i could actually buy a mint accord here right now with 25000kms on it for dirt cheap...thing is its right hand drive

his is european... most european hondas get a sportier look and engine... but I guess him having a carb throws that idea out the window.

hey well i saw wut someone did by flipping the air lid. i definately gained some power that i can feel. now its time for the K&N filter. the only thing that sucks is the price of one. ive got a speed shop that will send order and install my parts when im ready to get them. they are mostly obsessed with late 80s and early 90s mustangs. they do some bad ass work on them. i have seen the final product in action so they apperntly know wut they is doing. plus they said they will give me a break in the price since i have spread their name around my city.

So, how much hp will you get from the weber 32/36 ?

A20A1
10-27-2002, 01:16 AM
5% - 11% increase in HP.

the more mods you have the better the carb will be for you.

Mike's89AccordLX
10-27-2002, 01:26 AM
Sweetness, that's power for the buck. I think the Weber 32/36 is about $350. But I don't know if I could handle installing it myself. So, I'm going to check around to see how much it will be for labor. I'm having some carb problems in the mornings, so i'll just use that as an excuse to buy a WEBER!!! :rice: :bh:

dont get a pacesetter cat back. Make yourself a 2 1/4 pipe all the way back into a super turbo muffler that will give you a little performance. Definitely get a Weber and flip the air cleaner lid.

3G Jester

Or if you have a while till your next emissions=----get a used cat...gut the sucker.....and put that one in. then ewhenever you have emmissions again...put the original one in.

Flipping your lid is good...but get a K&N filter...50 bucks and reusible...all ya have to do is clean it with water and a little bottle of fluid they give ya. high flow--real good.

If you dont feel like spending the money on a weber...just take out your carb and clean the shit out of it. that will make it more efficient and such. even if it doesnt boost your HP it will still make things run a hella lot better. Plus when it is out you can adjust some stuff so it does give u a bigger kick---do a search on that one im not too sure., havent gotten aroun to doing it yet.
---If your handy welding..someone on the board took off the air filter box and actualy mad a short ram air pipe and filter forthe carb.....search that one too. or just browse through the performance section.

Good luck

custom air intake.... cleaned carb, port and polish, accel coil, new plugs/wires and distributor cap (gap plugs to .o55 or so), switch to synthetic oil (ie. Mobil One for higher mileage), DC sports header or Ceramic coated Pacesetter, high flow cat, 2 3/4 inch piping to a flow through muffler, possible cam reground, advance timing, either clean out the carb or do a swap. Could go to a webber.... or you could switch to EFI (with use of Donor car). Also I read something about a secondary vaccum to secondary manual conversion with our carbs.. opens them up at lower rpm for better throttle response... hmm what else... the basic flipped lid is alright... doesnt do that much unless you have a K&N filter... best bet... fabricate a CIA... A20A1 can help you with most of this stuff because he has, possibly, one of the fastest carbed cars on this board. But this should help you start a list at least.

weber carb conversion kit, bigger fuel pump, you can send the block to RPM or somewhere, get bored out, forged pistons, etc... or you can just get the valves oversized and head ported (much more inexpensive there), a racing cam, straight pipe, 1.75" is optimal, not over 2, use a SuperTrapp Muffler, you get a unique racing sound, plus you can put in different tunable ends to it, to make different sounds and tones, you can get a header, flip the lid on the carb if you're using the factory carb (huge hp boost), I ran drags with the hood off (way more power at higher speeds, air sucks right in), centerforce clutch (look at fastfours.com or other places), you can get upper control arms, tranny from a 2gen lude, you can get rocker arms with your cam...

rocker arms: $100
cam: $100-150
weber: $375-400
bored out @ RPM: $80/cyl + $20-25 per piston
ported head + valve job: $80/cyl???
straight pipe stainless steel custom bent: $110-130
Supertrapp: $125-150 (you can get one used somewhere)
header: I found pacesetter for $154, maybe at fastfours.com

you can port the head yourself if you want to... if you get a cam, you can get rocker arms, and port the head to complement it. Without a valve job, don't get a very wild cam, get something mild. replace the seal... that'd cost you whatever you want to port the head, maybe $80 at a specialist?, $125 for a cam, and $20 or less for a cam seal... so between $200-250. that's a good way to go for a real good boost in HP

If you go the exhaust route, either get just a muffler... just a pipe and a mufler.. or a header, pipe, and muffler. If you get just a muffler you can spend between $20 and $200. I had an old Thrush Turbo muffler for $20 from advance auto that worked fine, but when I moved to Supertrapp, I never went back. Don't get one of those cherry bomb coffee can things, those are so old and annoying and copycat. You can get a pipe bent or use yours if it's in good shape. I'd go for a bigger diameter if you're going to go further here. I had a straight pipe 1.75", and it was absolutely optimal. If you have it over 2", you have no velocity at the end to put pressure to pull the air out of the headers (delta P)... If you've got a resonator still (you want to be legal), you can put a bigger pipe after the resonator to try to make it better with performance (you won't get the velocity, the resonator/cat will be there anyway)... a new pipe will put you $150 down, and if you combine it with a header (probably $200, I found one for $154+ship, but that's rare), and you'll have some great high flow. Now to make this work (unlike everyone else), you should advance your timing (especially if combined with a cam and rocker arms or something). Without the 7 or 8 degree timing advance, I missed 21hp and 11 ft.lbs... (yes, I dynod it).. very useful. The whole exhaust, for between $400 and $600 for everything, or $20-300 for just the pipes, you'll find anywhere from a 10-35hp boost (with timing advance)... combined with the cam and carb and everythign else, you'll have one kicking machine.


you could get a bigger fuel pump to complement your weber carb (which would also go nice w/a cam, but is a great HP boost alone)
For $400-$420, you can put together your weber carb and high psi fuel pump... not as much of a boost (that I know of) as the whole cam route (unless you get JUST the mild cam... then the weber will give you more), but still a worthy investment. Combined, they add much more HP than they would alone, and you'll be runnin with the big boys real well.

you could send it to RPM for an overhaul, probably $400-450 for boring out/pistons (you'll have to put it together pretty much as far as putting the carb and all that back on), $300-400 for the valve job and ported head (if you don't port the head yourself)... so if you put $1800 into your motor, you'll be pullin LARGE AMOUNTS of horsepower, smoking fast cars, and sounding like a racecar... (you could rev to 10 grand too). or you can go down one of the routes in each respective paragraph I wrote down.

Buy pacesetter headers, weber 32/36, straight pipe, custom exhaust, ram air setup, cam, light wheels, ignition system. (not in any particular order)

moveing and merging thread...

With a race cam 1.75" is too small in my opinion... I've been increasing the diameter of my exhasut pipe little by little and I get a more pick up each time.
When the race header goes on it will be bumped down to 2.25" for a short length... then run on into a 2.5"

how do you flip the airfilter lid? just take it off and turn it over, what is that thing anyway?

damn. i had forgot about this thread. glad to see someone remembers. im still wanting to stick with the stock A20. i have heard improved things about Gude performance. hope those things are right. i still wanna get the cylinder head and cam done.
