ca questions?? confused??

Post by **osofasts13** » Sun Dec 07, 2003 9:33 am

hey i had a couple of questions... okay. Why would you buy a motor just to rebuild, isn't the whole point of buying a motor is to take out your old beat up one ( which you didn't want to rebuild ) to put in the older but less used motor?? i was thinking of buying a ca and putting it in my s13, obviously because of all it's good traits, but i'm having some second thoughts. i currently have a ka24de, and would like to swap to a ca, but don't have the money for the rebuild, if i did i would just rebuild my ka. so enlighten me please ca Gods, do you mean rebuild as just putting in new gaskets and belts or crazy stuff like new internals?? and how much does a rebuild on a ca usually cost?? i plan on running the ca with a t-28 (off a gti-r), and pushing near 250 hp. and should i get like a stand alone fuel system, or can i just get a retuned ecu ( what company tunes ca ecu's well? ) , which is cheaper and alot easier, i live out here in mi where there is not alot of tuner shops, so no one to dyno and tune my stand alone. thanks and please enlighten me, kind of a noob to the whole ca scene, but have lots of experience with nissans and sr's. and i did do some searches but nothing with the info i need.

You don't NEED to rebuild. I didn't do anything to the CA thats in my car now except change the timing belt. It should be good to 300hp internally just the way it sets. Some people have had problems with headgaskets, but I personally feel they were usually due to poor tuning or poor building. Get the CA and drop it in. Then start having fun!

Yeah, everything he says. Just get your engine and enjoy it. I've heard too many people talk about rebuilding an engine that they just purchased. Kinda seems unnecessary if nothing is wrong with the thing in the first place. And figuring the money you've spent to acquire the motor, you would be putting in extra work. If you were building a serious motor, then I would say go for it. But if you're going to do some everyday driving and looking for some nice power gains, keep what you got and have fun.

thanks guys, just kinda confused about all the comments about rebuilding the ca when you buy it because of it's lower milage. would you guys change any of the seals, vacuum hoses, or gaskets, while it's out of the car?? anything i should change while the motor is out, like stuff on the motor that usually breaks or commen maintenance stuff that is hard to get at when the motor is in?? another question i have is who tunes a good ecu for the ca, i heard the ecu is easily tuned and is pretty cheap. what kind of horsepower should i see with a t-28 and all the commen fuel upgrade??

Post by **Trigger** » Sun Dec 07, 2003 9:33 am

from experance i would change all the vacuum hoses. change oil and filter and let her ride.....as far as tuning...standalone is your best bet but you can get mine tuned ecu's all day long on ebay. They work good. or just pick up a piggy back if your not trying to go to big....with the right fuil and a t-28 i would say 275-350hp...correct me if i am wrong guys

Post by **r34 gtr** » Sun Dec 07, 2003 9:33 am

i changed the water pump, belts, oil and filter. id say you could fairly easily make 250hp with that stuff. i dont think you could make 350, that seems a little out of reach of a t28. id say a good tuned ecu should be fine for 250hp, but you can go with a standalone if you'd like. you may want to change to a metal head gasket if you plan to push around 300hp, the guys over the pond say the stock one is good to 17psi but you may not have the resources to tune the car as well as they can.

I changed the belts and hoses and I would have changed the H20 pump and the timing belt but it looked like they had been replaced recently, so I left them alone. As for the ecu, I think Jon (slw240sx) has the ability to burn chips. Tell him what you want and he can get you set up. I know he's got a setup for Z32 MAFS, 440cc injectors, and I think 10psi. We're going to use my setup to tune for Z32 MAFS, 550cc injectors, S14/S15 T28, and 12psi. I still have stuff to buy though so he prob. won't have the specs for that untill after I get my tax returns and I can afford the MAFS and rebuild my turbo. As for true tuner shop ecu's you JWT's has a setup, but they rape you. And you can get jspec tuned ecu's on ebay, you just have to keep an eye out for them. The only problem with the eBay ecu's are that you usually don't know what they were tuned for.

not to be a thread jacker, i was gonna ask the same thing as osofasts13...

but isnt easier to eliminate potential problems while the engine is out, rahter than to work on it after its in the car. i was planning on getting the whole engine gasket kit, and replacing the pumps, alternator, starter, rod bearings, and timing belt before i put in the engine... ive also heard the turbo will crap out on you bc its old, so i should look for t25 off the SR or something... just planning to run it all stock... no major upgrades

im hopefully getting hooked up with a CA... and hooked up from a nissan dealership my friend works at

oh, and i heard piston rings... or is all this bs if youre planning to run stock... just drop it in and be happy right ?

Post by **r34 gtr** » Sun Dec 07, 2003 9:33 am

dont need to worry about rings, if you are worried then run a compression test. yes, it is easier to work on the engine while its outside the car, so that would be the best time to replace stuff. you dont need a whole gasket set and bearings, but it may be a reasonable idea depending on how many miles your engine has on it. i would highly doubt that it would be needed though. for the price, i might look for a better turbo than a sr t25, maybe a t28 or something bigger with a t25 flange. hks turbos pop up all the time on ebay and you shouldnt find it too hard to pick one up for a reasonable price. on a final note, once that engine is in there is no way in hell you will be able to leave it alone. it will star small and snowball until you are spending half of your income on the thing. good luck with it though!

agreed nismod....i feel your pain

These are good little engines. Believe us when we say that if they seemed to have some inherant problems that needed remedied while the motor was out, we'd probabally know about it and would have told you already. I would say replace all the belt, the water pump, the timing belt, new/er turbo, and then have fun. I think my motor had over 100,000km on it, and I'm not haveing any problems with it (besides a leaky STOCK turbo).
