I just bought a 90 CRX with a B16a for my son last week. We took it to an 1/8 mile track last night and this was the best pass: 2.42 sixty ft , 10.38@69.2 mph. I am no stranger to racing, I havs a LS1 Camaro that runs high 6's in the 1/8 and high 10's in the 1/4. I just dont know much about Hondas yet. I was expecting this car to atleast run mid 9's.
The guy I got the car from says it has JE 11:1 pistons in it and the owner before him had a turbo on it. Didnt make sense to me. It has a DC header, some kind of exhaust, cold air. The computer says Erics Racing Engines on it. It has an air/fuel gauge and it shows rich most of time, the spark plugs look good though. I think one problem is the tranny, it seems to be long geared. Shift into 2nd almost at 1/2 track and hit 3rd at the finish line.

Could the computer be tuned for a turbo set up maybe?

What tranny(cable clutch) should I switch to?

I'm going to check the compression this week, what else should I look into?

 

start by really figuring out what the car has

 

I'm working on it. Just imagine you being a Honda guy looking at my 02 Camaro SS and trying to figure out what all it has when you have no reliable info on it.

 

there should be a gold label on the tranny to the left of the header find out it should start with a y tell me what the comes after y and we can figure out the tranny u have btw those are very slow 1/8th times for a b16 swap crx

 

y1 and j1 are pretty good ones to have but what are you guys revving the motor out too???

edit also to help out here are some tranny codes too look for

y1
j1
s1
ys1

 

The label on the tranny starts with A1.

Tryed ranging from 7500 up to about 8500. Vtec kicks in around 5800.

 

a1 im pretty positive thats an ls tranny but not sure but its a long geared tranny which is no good i would look for a y1 or a j1 tranny, or a s1 b16a tranny careful though because some ls trannys have the same s1 code.

but the car still seems like the power isnt there when i was running 14.1-14.2's my 1/8 times were like 9.1-9.2 with 78-79mph you should be around the 9.5's and mids 70mph traps.

Holy %&^%&ite BatMan!!!!

big kudos to you on the wonderful purchase for your son

I wish I had got such a thing, but alas, when Iwas his age they did not exist.
Though I did get a 1978 cvcc HB so I suppose I was lucky tho I was too young to know what I had.
I hope he knows what a rare classic he has.

Is there a site to look up tranny numbers?

 

find out the real story of what was in the motor, its not a fast car really... and those 60 ft times are hurting.

Oh and welcome fellow ls1 and honda owner.

 

Its has to be loosing power somewhere. I know it should be faster even with the long geared tranny. I'm thinking it may be tuned for a turbo if really used to have one on it. I'm assuming that would be too much fuel and not enough timing for a N/A motor.

I'm going to check the compression today or tomorrow and go from there.

a1 is not a short geared tranny, tuning could be possible but if it also had 11:1 comp it wouldn't be turbo atleast on pump gas..

I would do that and if you can find a local tuner do a dyno pull with A/F and go from there.

 

you probably have a ls tranny,,cause if you had a b16 tranny you would seriously know it....Go on the highway in 5th gear at about 65mph,,then come back and tell us what the rpm is at..

also like others said you have to find out what you have in that car,,the computer says erics racing? that really doesnt mean nothing i have a aem sticker on my stock pr3 ecu doesnt mean its aem....look at the ecu see if you can find the code,,it should say "Pw0" (obd0) or "pr3"(obd0 and obd1)...Then find out if its obd1 or obd0...if its obd0 you'll see a little glass window for a red light that tells you the codes,,if its obd1 there will be no light/window on the ecu....did he give any kind of proof that it has je pistons? receipts from je? box? machine shop ? also so you know, a B16 crx is not fast,,,,,,its "quick" so dont expect much from it on the drag strip without turbo or serious all motor build...and what kind of a/f gauge is it? is it real with a wideband o2 or one of those bullshit ones that show rich/lean and flashing lights?


and im not saying your stupid or anything but are you sure its even a b16?

 

Well, I am a little on the stupid side when it comes to Hondas. But I have learned some stuff in the past few days. It is a B16A, its stamped on the block. I've done enough research and looked at pictures to know that much. Even if the motor is stock its easly worth what I have in it. But a stock B16A should be faster. I was hoping for real low 9's and expecting at least 9.9's.

It must be obd0, it has the sight glass on the computer. I looked last night and didnt see a P# anywhere, I'll check again this evening.

I'll have to take a good look at the A/F gauge. I know it has like a wrap around light bar that starts off red on the lean side and changes colors as you go around the gauge.

My hint will be don't trust that A/F gauge they are light shows, better to go run on a dyno.

 

Just done a compression check. The first thing I noticed was all the plugs are black. They looked fine the day after I got the car, must have been a fresh set. That leads me to believe that the A/F gauge is somewhat correct when showing rich pretty much all the time.

Cylinders read 200, 200, 200, 180. Dropped a little oil in the 180 and it jumped to 225.

Found the label on the computer, its a pr3.

Also looked at some of the info the guy I got the car from had sent, he says it has Skunk2 cams. I'm not sure if he really knows.

The second you got wot they show rich, but yes you are right black = rich.

comp sounds healthy, you really do need to find what the heck the owner stuffed in to the car.

PR3 is obd0 b16 ecu.

 

yeah i second that find out whats in it. pop off the valve cover and see if there are aftermarket cams in it, if not he is probably lying about the pistons as well. my b16crx is not slouch but its not FAST, its pretty much bone stock but I do have the best cable tranny the YS1, it is very short geared , my 1/8 are 9.6 at 75mph and 1/4 14.9 and 98mph. It would seem like the times are not that far off for your b16 with the ls tranny

I have a B16 with Y1 tranny, Is ir good or bad,
Gears are very long

 

a1 tranny is a ls tranny. shorter than the hydro ls though. the a1 has roughly around the same gearing as a gsr hydro.

with my b18b with a a1 tranny i was pulling pretty much the exact same times you are, did a 15.5 in the 1/4.

also unless that car has a wideband in it, that a/f gauge is just a show, it can only read really rich or really lean. it doesnt have a linear output to measure the whole band, its only on or off sort to speak.
