Conflicting CRX Specs

[szmidi]

I've been searching on the net for some stock et times and power outputs of the gen2 CRX so i can compare to other cars ratings. I'm looking at buying one and want to know the level im be starting at so i can set a reasonable level to hope to achieve (NA). All sites are different, either hp or kw and either at fly wheel or at wheels, but none seem to give a straight answer.

SO, what sort of power would a d16a8 in a gen2 CRX put out? if someone is full of answers then give 1/4 mile, kw at wheels, torque, 0-60ft with decent driver, and possibly a comparision of what type of cars it will keep up with stock.

And how much difference will the basic I/H/E, possibly a chip, make to the above. and What would a stock ba16 conversion in a gen2 put out?

i just hate how cars put 237hp to beef it up a bit, when really its 180kw and only 100 at the wheels or something

[Klayemore]

stock d16a you'd be looking at around 80-100kw? probably a low 16 sec 1/4 mile.
stock b16a a bit more than that and a mid 15 sec 1/4 mile.

KJeep in mind that they are very light cars, so they don't need huge power figures to compete with skylines, WRX's etc...

[SINISTR]

Factory engine HP:

D16A8 124HP@6600rpm (96Kw)
B16A 160HP@7200rpm i believe (120kw)

Factory wheel HP:

depends on the dyno and atmospheric conditions but I found a good indicator for wheel HP is taking the factory KW figure and subtracting a bit...

D16A8 in the vicinity of 90HP@wheels
B16A in the vicinity of 110HP@wheels

Intake/Header/Exhaust

D16A8 around 100HP@wheels
B16A around 120HP@wheels

1/4 mile times:

Stock D16A8 - low 16s
IHE D16A8 - mid/high 15s

Stock B16 - high 15s
IHE B16 - low/mid 15s

A stock D16A will beat most NA 4s and 6s and keep up with some 8s
A worked D16A (depending on mods) can beat 6s and give 8s a scare

A stock B16 will do the above and give 8s a scare
A worked B16 will do the above and sometimes beat 8s in the 1/4 (depending on the overall speed as 8s get quick topend)

its a rought but just about right type of a guide.

I can tell you my D16A8 made 102HP@wheels after installing I/H/E and gets me down the 1/4 in 15s with a bodykit and 17s.

[szmidi]

KJeep in mind that they are very light cars, so they don't need huge power figures to compete with skylines, WRX's etc...

yeah i understand that, but until i own one and can get it on the street i cant compare because none of the figures ive found have been expressed by a uniform measure (ie.kw at wheels)

thanks for that, and if anyone has more info then please still post it

[szmidi]

Thats what i like to hear. if i can embarass some tough guys in commodores ill be happy :D

i drive a stock ef8 (gen2 sir crx, b16a) and i cant compete with the turbo skylines, or any wrx. maybe the rb25de skylines etc but the turbo cars, forget it on a stock b16a, even more so with a d16a. they just dont have the torque. simple as that :(

[szmidi]

I just want absolute confidence in beating idiots who have borrowed mummy's car (Mazda 6, commodore, etc) which i am certainly not guaranteed with my current car (SOHC) :(

and CRX's are the best looking car ever created, thats a big factor too

[Klayemore]

and CRX's are the best looking car ever created, thats a big factor too

Very true :p

I have a slightly worked ZC (pod, extractors, exhaust, HD clutch) and it keeps up with and beats some V6 commodores etc. Fkn bogans :D

A stock b16a will not beat skylines etc - it has the potential too is what I mean.

[SINISTR]

Don't street race for starters - take it to the track!

I've beaten a new Mazda6 on the strip and have definatelly upset commodores in the past.

CRXs in general - unless you put a B18C or spend crazy amount of $$$ on the engine will have a hard time beating anything thats Turbo (except for Pulsar ET which i killed in my auto CRX 1.5L LOL). They are however awesome as a track car, put a few twisty corners in the way of a CRX and it will breeze through them like it was a straight road while all the other cars will struggle.

CRXs are not built for TOP speed but you will upset some cars even with a D16.

[szmidi]

[QUOTE=SINISTR]Don't street race for starters - take it to the track![QUOTE]

No, im with you there sinistr, im a corners boy, which is how my current car is set up, but i get killed once it comes to acceleration. and there is no track racing here anyway. i can easily hit a roundabout and take off now but its not as humiliating as losing of the mark

cheers all

[Klayemore]

Yeh if u want straight-line power - B18C, K20A or turbo the stock engine - which is prolly what I'm doing in the future.

As SIN said, CRX's are built for track - alot of people get quite surprised with the handling capabilities of the little things.

[szmidi]

I dont want to go insane, im lookin at about 100kw at wheels or 15 sec quarters if that is not a mission out of a NA non-vtec, and ill be quite happy. just need more than what i got now and to piss off those *ahem* bogans

[j3z3z]

i drive a stock ef8 (gen2 sir crx, b16a) and i cant compete with the turbo skylines, or any wrx. maybe the rb25de skylines etc but the turbo cars, forget it on a stock b16a, even more so with a d16a. they just dont have the torque. simple as that :(

dude what gearbox you running or what is wrong with your b16 i keep up with them all the time and wrx i beat to 100.... could all be down to the driver

[SINISTR]

100kw at wheels isn't going to be easy with a D16A8 - will require a boost in compression, propper ECU, maybe injectors etc etc...

with I/H/E, cams and gears and a piggy back ECU you can get around 90kw@wheels - about thesame HP as a stockish B16A.

as I said - with IHE and good driving you can already get 15s out of a CRX. Put some other mods like suspension and tyres and you got mids... anything extra will just lower your time with good driving.
B16As can run 14s with good mods.

[SINISTR]

dude what gearbox you running or what is wrong with your b16 i keep up with them all the time and wrx i beat to 100.... could all be down to the driver

hehe... a good WRX driver will leave you for dead in the first 50 meters LOL.

[Klayemore]

I want to take mine down the quarter soon - I'm thinking I'll get a high 15, as it keeps up with a stock SiR. I can only hope :p

If I can get mine into the 14's I'll be happy. A small (8psi) boost setup should work wonders :D

[qstoria]

just the stock Y1 gearbox with LSD. some of the synchros are worn and grind at high revs but even if it was rebuilt i doubt it would help me close the gap. the engine is fine also.

u keep up with them off the mark or rolling? off the mark i dont have a chance, rolling maybe but like i said before, b16a dont have the torque of a wrx. from my experience i wouldnt tell someone looking to buy a stock gen2 crx that they could keep up with wrx, skylines etc

so like sinistr said, if the wrx drivers have any idea what they are doing they will leave u for dead.

thats about perfect sinistr. i'll probably look into cams, injectors and ecu mods after IHE but depends on $$$ for it all. i think ill be happy once i have a CRX for my very own. you've talked me into it :p

[SINISTR]

another thing to keep in mind - if you don't mind 'hunting' for mod parts then D16A8 is a good engine. B16As are obviously a bit better supplied out in the world of mods.

if a WRX or Skyline driver - knows how to launch his car, the race is over sooner than it even started.

[bal]

yeah have to agree with qstoria on this one with out a turbo, serious work or k20 wrx will dominate even with a bad driver in the wrx they pull to hard down low for the b16 i have raced a stock 98 rex and an 06 rex same result get like a car and a half off the mark thne pull away slowly but surely admitantly the race didnt go for long due to a red light but i could see what was going to happen. OWNED give it 12 motnhs and ill get infront of them VTEC YO

[szmidi]

To throw another spanner in the works, this all stemmed from this reply i got from a CRX seller

---------------------------------
Before Chip
Max Power 61.5kw @ 6440 RPM
Max Torque 315.9Nm @ 2951 RPM

After Chip
Max Power 70.0kw @ 6817 RPM
Max Torque 334.6Nm @ 3085 RPM
---------------------------------

This sounded a bit low so i went searching, what to you guys think of this. He said the chip made a big difference to the power. he also said that was power at the REAR wheels, :confused: go figure?

[SINISTR]

what chip is this?

if its a Unichip Gold 98 or something like that - yes - you can get improvement over stock but they won't tune the chip for anything other than a generic brand of intake, headers and exhaust.

I won't even say anything about the 'rear' wheel power thing but if thats the case it sounds dodgy. Its not off Ebay is it?

[szmidi]

I think he said PowerChip, its apparently programmable and what not. ive decided not to go with the car for other reasons anyway.

and no not off ebay, im not that silly, um just carsales or carpoint or one of those.

what do you think about only 70kw after the chip & IHE though. you said about 90kw wont be much trouble with basic mods, has he read the dyno sheet wrong?

[SINISTR]

PowerChip Gold is about $500+ and yes its programable but only for certain things - they won't tune for cams or gears etc.

I said about 90Kw shouldn't be much of a problem but not just with IHE and a chip - you need Cams and cam Gears and a good tune - more like a piggy back SAFC or VAFC, Hondata or Emanage.
120HP@wheels (90Kw) is only achievable with Cams/Gears and ECU.

70KW (100hp) is good for stock car with IHE and chip. Its achievable. I've got about 76Kw (102hp).

300+ nm of torque? would be nice but i dont think so. a pretty worked k20a maybe

[Dxs]

CRX's in all forms are torqueless. If you want one for street there are much better alternatives.

They are basically meant for mountain runs or the track where revs can be kept above 3.5krpm. If you want a good street machine nissan turbo is where it is at, or maybe something with more displacement such as h22a equiped cars.


People who say crx's can keep up with wrx's are on crack. Like always with the internet false info spreads easily and everyone jumps onto the bandwagon that because the crx is light that it is an effective street car. I have spent around 2k on a top full exhaust for my b16a and i have noticed slight more torque and power and throttle responce. Spend the same on a turbo and u will get 35kw at the wheels.

So yeah, if u want track or mountain runner or even ricer then get a crx... not the best street machines though

[SINISTR]

sh*t - didn't even pay attention to the Torque - 300NM? maybe on the moon :P

[Klayemore]

My CRX has quite a bit of torque I must say :) Its the perfect torque range for a turbo set-up

[j3z3z]

hehe... a good WRX driver will leave you for dead in the first 50 meters LOL.

he is a good driver and he was extremely suprised that i pull away above a certain speed

[j3z3z]

just the stock Y1 gearbox with LSD. some of the synchros are worn and grind at high revs but even if it was rebuilt i doubt it would help me close the gap. the engine is fine also.

u keep up with them off the mark or rolling? off the mark i dont have a chance, rolling maybe but like i said before, b16a dont have the torque of a wrx. from my experience i wouldnt tell someone looking to buy a stock gen2 crx that they could keep up with wrx, skylines etc

so like sinistr said, if the wrx drivers have any idea what they are doing they will leave u for dead.

it is from a dead stop, both launching, i launch off 5500 and i get him at the change to 2nd then its pretty much even stevens till a certain speed where i pull away

sorry forgot to state i run on 14" rims and my car is stripped

[qstoria]

all i can say is u must have a pretty neat b16a and have stripped 100+kg from ur ef8 cos bal drives an EG hatch with a rebuilt jdm b16a and CTR extractors and the 98 and 06 wrx owned by friends cleans it up. his eg is quick but the wrx is quicker. as for the drivers, obviously we arent pro's but like u said slipping the clutch at around 5500 seems to work best for the
b16a. just not against wrx thats all..

[j3z3z]

his wrx was an 05 he just sold it and brought a hsv clubsport and also r33 gts-t are pretty easy to beat if they are stock.
and no im not a pro either but i do rate my driving pretty highly

[bal]

i find that very hard to believe i have a 2000 model JDM b16a with CTR headers, full 2 1/4 inch xforce exhaust i weighed my car (EG hatch) yesterday and it was 1000kg neat im not the best driver but defenatly not the worst but either is my brother with an 06 rex (stock) and my friend with a 98 rex (stock) both have the upper hand from the word go

so i dont no whats wrong with the cars u are racing but they better get them looked at if u can get in front of them from the change into 2nd

[qstoria]

this thread starting to wonder off track a bit now... im sure the whole b series vs wrx vs evo etc etc has been done to death in many other threads.

this one it hasnt really helped szmidi either. now he/she has conflicting stories about b16a v wrx etc. one thing is for sure is that if u own an aussie ED9 crx with the d16a u WILL not be close to wrx, any 6's or 8's in a straight line. really really tight twisties maybe but lets face it, most roads are not like that.


buy the crx and enjoy it for what was designed for, which isnt straight line speed but for its classic look and its handling.

[szmidi]

thanks mate.

i dont expect to beat anything turbo. i want a crx for its style, but id really enjoy not gettin beaten by any old stock or I/E modded cars

[j3z3z]

i believe with an ed9 crx with a b16a conversion he will go pretty well as being lighter then the ef8, my ef8 is on 955kg on a full tank

[j3z3z]

this thread starting to wonder off track a bit now... im sure the whole b series vs wrx vs evo etc etc has been done to death in many other threads.
b series vs wrx vs evo evo wins wrx sti 2nd equal 3rd standard wrx and b series


so i dont no whats wrong with the cars u are racing but they better get them looked at if u can get in front of them from the change into 2nd
nothing is wrong with their cars, ask felix on the forum i have long gear ratios 80ks in 1st at 8200rpm 120ks in 2nd at 8200rpm they change gears before i do that is where they loose out im sure my lsd helps when i launch

[qstoria]

i have long gear ratios 80ks in 1st at 8200rpm 120ks in 2nd at 8200rpm they change gears before i do that is where they loose out im sure my lsd helps when i launch


what gearbox are u running with? or are u running upgraded internals in the stock gearbox?

[j3z3z]

its a ys1 gearbox case... as being imported i do not know what had been done to the GB but i know motor is running stock parts at the moment till i swap it
