got some info on the ca vs sr

[Turb0wned]

just as hard of a fight as the ka-t vs sr20 the ca is acually a really impressive engine...

[Turb0wned]

what do you guys think about these 2 engines...?

[Trigger]

yep thats why we like the little motor

[Trigger]

if i didn't go with the ca i would have turbo'd the KA....the SR is a great engine but not for me.

[Guffed]

sooooo....the ca18det is better. I hate all those "vs" arguments. It all comes down to which motor you own. I, for one, own the ca18det so guess what? I like it better.

[gore]

I look at it this way, they put lots of money into developing the CA and not so much into developing the SR, cost was an issue when they built the SR, so it means they cut costs where they could.

[CA19DET]

i like both, and want a SR powered car too, i see no real benifits or dissadvantages of either...

[boost_boy]

Quote »i see no real benifits or dissadvantages of either...[/quote] I do and in both of them, but pound for pound the CA is the better engine due to sheer strength and parts flexibility. SR is good if you just want a turbocharged street car and the CA is for the twisted individual who has no limits.

This is the truth! I really like CA's a lot and wanted one...the problem was that after getting burned I refused to buy a motor I couldn't see in person, hear start up and inspect before paying...or buy from a reputable place which I tried to do with an RB just couldn't get it fast enough and good enough to satisfy me. Since those weren't possible for me I went KAT. If I could have found one in Dallas I'd have stayed in the CA game though. I never seriously considered the SR though, darn coke can motor Perhap's in another car someday I will get to do a CA...it'd be quite fun!

[boost_boy]

The turbocharged KA24E/DE is a great start and see it being no worse than an SR20DET. It puts out gobs of torque and can put out good power on stock internals if done correctly. The SR can put out good #s on stock internals if done correctly as well as the CA. But when it gets right down to the nitty-gritty, both the KA and the SR were built when Nissan's pocket book had a fat a$$ hole in it. Timing chains are a nuisance to be screwing with and the KA, SR, and the GA16 were all given chains.

The KA had the cast iron block because of the duties that will be bestowed upon it; and the SR was designed with saving $$$s in mind= cheaply done! Contrary to what anyone says, it shows. It also shows that the KA was not really meant to be turbocharged and it shows why the VG30DETT, RB20DET, Rb25DET, RB26DETT, CA16DE, CA18DE, and the CA18DET all share components of some sort and all are designed with the same technology in mind. If the CA was built in 2.0 litre form or even 2.2litre, it would be extremely lethal right out of the box. The coke can or SR is more of a fad that started with an amazing company called "JUN" that exploited this engine to the max with major dollars and R&D involved.

The KA24 could very well be a good drag engine if someone would dump some good money and technology into it, but as of today all posers with the KA-T have turned into wrenchers servicing burned pistons, blown headgaskets and things of that nature. SR people are buying rocker arm stopppers and sleeves and trannies and things of that nature and my condolences go out to them. Thanks to the fast and the furious, the SR20 has paid plenty of people's bills including some of mine, so I'm definitely not hating on it.

But if you're a wrencher and look at the big picture, one would see that the CA18 is a far more simpler motor to service and can give stellar performances just like it's bigger displacement family members. As a supporting detail, I would never own either as the CA18DET has spoiled me rotten and makes my mechanic adventurers much more soothing compared to when I wrench on turbocharged KA24DE's and SR20DET engine alike.

[Nathan]

True the stock internals on the KA suck...that was actually one of the reasons I chose it, I knew whatever engine I got I wanted to tear it apart and at least partially rebuild it so my KA's all forged inside now I would have had to do a lot of work on a CA to get it up to the brand new condition I was looking for too and ultimately the price would have been about the same no matter what You know what would be cool? If someone imported factory short blocks for CA's from Nissan Japan...for anything close to a reasonable price that might have sold me on the idea just so I could start over with a fresh engine I also could not agree more about the CA being built larger out of the box, it WOULD be lethal! The 1.8 liter is still nothing to sneeze at though It has a bit better flowing head than the KA from the looks of it as well, particularly on the exhaust side. I agree with you on the chain's part ...they suck balls I'd rather have a belt for the cheapness and ease of changing one out with no guides to go bad (speaking of which, it'd be badass if someone could produce a conversion that switched it over to a belt while giving the KA a lightened pulley...).

[Trigger]

ahhh again boost_boy comes and tells it how it is..nathan i agree that would be nice to change the chain to a belt on the ka...would perform alot better i think

[McAdam]

I would have to disagree with you guys on some points. I prefer the chain to the belt, especiall when it comes longevity. I have a 280zx with over 230000 on the clock, same good ole timing chain. Now, I am working on a KA/L hybrid, best of both worlds. I do have to agree with you on the points that the CA is the best factory produced of them all. damn, they are tough little motors. I hope to get mine running soon, lol. all I need is a plane itcket home and a couple hundred dollars.

McAdam

[Nathan]

But chain's are such a giant pain in the ***...true they last for ages but are still expensive and annoying. Sorry to take this thread a little off track...CA's kick SR ***

[Turb0wned]

there both great engines i think im starting to like the ca a bit better also its cheaper and the money left over can do other things..... but i think there both really good and it just comes down to ur taste

[Turb0wned]

i also like how ahead of its time the ca was

[14.5drift]

Not to rain on the parade but any one who has owned both prefere's the sr over the ca ( displacement I guess ) like boostboy said, a 2.2 from factory would be amazing. One thing that makes me wonder is the sr while being the less advanced motor still made better use of it's 2.0. The S14 sr makes like 115 hp per liter, while the ca makes only 97.2 hp per liter. If the ca had a more efficient head than why does it pack less ponies per liter?

[Nismo1182]

Displacement and a smaller turbo.

[NeedCAforS13]

Paul (MovingViolatin240) has had both. He had a sick CA, and now he has a sick SR... both engines are plenty of fun:)

Sean

[CA19DET]

i dont want this to explode into an arguement, but i have seen on freshalloy currently they have members with ~500whp SR20DET's running stock blocks (stock pistons and rods without a rebuild) - dyno charts posted in the furums.. (obviously running stand alones, cams, big turbo etc)

there is a current battle between the stock block SR's going on over there and i think they have reached in the mid 500whp range!!!! thats 500+ wheel horsepower fellas... on a stock block... not saying the engine will last but neither would a CA past about 400 with stock internals and the kind of boost they are running. soem with stock headgaskets even!!!!

this means that the SR can take some jamming... i have not seen a CA put this down in stock block trim yet!!! and alas SR parts are much more plentyfull and easy to get (pistons, rods, manifolds, cams kits etc)

now i know with the right internals the CA can easily superseed these goals without having to reline the block and worry about sleeve wobble etc...

as i said in the past, the SR is great if you want to jsut start it up and boost the hell out of it till it breaks (especially wiht the S14 or even S15 motors with less mileage), and the CA is better if you plan on rebuilding and going the whole hog on the engine... cause most CA's will need a rebuild as they are old..

but pound for pound what ever is best is whatever is most available to you, i had a CA18 cause of the lack of SR20's around at the time, so i put a CA18 in my project car back then, then when i sold the car, i kept the engine, got a silvia with a CA18DE and decided it may be easier to rebuild the CA18DET and swap out the DE later on... if i had a SR from before, honestly i would have build a SR, and honestly it would have been finished already cause of the availability of parts...

if i could do it all over agian i would go SR, or even RB25, but thats not going to happen, so i am going CA and will boost the snot out of it, and then dump a 150HP shot of N20 to really see what the CA18DET is capable of when the same bag of tricks that would be used on a SR are thrown at the CA...

[boost_boy]

My attempts are simple; to push my CA18DET with stock bore (1809cc) forged psitons and rods right out of the ballpark. I'm not scared of the infamous 30psi of boost. I'm going to try and max out my duals SBC at 2.5bar (i don't care). But I'm going to do it in a professional, well planned manner by increasing my fuel curves above the limit to ensure that it doesn't run out of fuel. So far my tuning is up to 26psi without blowing up and this is without dyno time, so my familialarity with the CA and the SDS has paid off, somewhat. But I really do think that the SR is good for throw it in the car and boost performance. And the CA is "Shake what yo' momma gave you engine" that'll give you back what you put in it. It boils down to this "Tuning". If yo' stuff ain't tuned, you'll get to know your internals on a face to face basis {Guaranteed}.

[drumma022]

Hey Dee, well I hope to be posting some 400+ dyno numbers in about 1-2 weeks now. Once that is done, I will hope to start up a new project and selling off the motor as it stands, or in piece it out. I love this motor and its capabilites to rev out. A few weeks ago, I was hanging with a 460rwhp 300zx into 5th gear! I was happy about that for the night, since I was at about 20psi.

I am planning in maxing out this turbo on the dyno. To give you an idea of where it stands at low boost, I had posted 243.8 hp and 189 tq at .6 kg/mm (8.5 psi).

[Nismo1182]

Nobody wants to see how far a CA will go on stock FORGED internals. Every shop is about the SR and how far it will go. Its all about the tuning. Im sure a CA with a built top end and stock bottom (Like many shops with SR's have) will pump out some impressive figures.

Sure the engine is old, but 1-2 years is hardly THAT old. I mean, say your 21 years old and you want to go out with this girl thats 23. Now is she OLD? Now usage is another story

[14.5drift]

So whats gonna happen when one of the internals fails, just a rebuild or would you need a new block?

[Nathan]

Depends on what type of failure you have...you throw a rod you'll probably ruin the block, you hole a piston the block will probably be just fine.

I seriously doubt your engine will fly apart at say 25lbs of boost, so go for it and keep us posted.Quote »Im sure a CA with a built top end and stock bottom (Like many shops with SR's have) will pump out some impressive figures.[/quote] The CA in my girl's car has been in action since 9/8/01 and has been abused to the point of no return. I mean revved to 8700rpm on a regular basis, beat-up numerous big name 6 & 8 cylinder super cars, smashed big name production 4 cylinder cars and just completely feasted on honda, nissan and toyota rice for an appetizer; and the thing is still performing after being involved in 2 accidents that has totally totalled 2 1990 nissan sentras. So hopefully soon, I too will be taking it to the dyno and winding the boost up on the stock internals of a well used engine with the only addition being a pair of HKS camshafts. Forget about a built head and wicked camshafts and big stupid turbos that are only good for assisting with big #'s on the dyno, my CA18 powered sentra is a real-time everyday car with A/C, P/S and a whole lot of creativity into otherwise unsuspecting grocery-getter. I'm looking to clear 400+whp on an abused, internally stock CA18DET and thy will be done. And Ray, as long as you don't get too cute on the timing side, you will supercede the 400whp mark with no problem; and this I know. Good luck and represent!

[Turb0wned]

how much have you people gotten one for?

[Turb0wned]

by that i mean the ca

[boost_boy]

It can be anywhere from $600-$1000 just for the motor alone. Complete motorsets from $1000 to as much $1600.

[Onizuka]

all im going to say is:

COKE CAN MY ARSE! If you think the SR block is weak by any standards, you dont know enough to be commenting on the subject.

I like both motors, CA are just hard to find
