This guy i know who sold me his sohc ka runs sooo awesome, has 86k mileage. Same guy may sell me his ca18 turbo because he got a new turbo and plus another new ca18 motor, so i may buy that if he's still willing to sell. So just wondering how good that turbo would run for the sohc ka with stock internals and i'll probably start at 6 or 7psi.

Very good response, but power will taper off past prolly 5000rpm. Great for a street driven car with quick spool/power avaliability in mind.

Bad turbo...to small...if you have a turbo now, replacing it with that one is a bad idea.

nah dude i don't have any turbo as of now... this will be my first. I've been piecing everything together as of now and pricing it all up.

But the only real good turbo i can get my hands on is the ca18 turbo. I can't find anything else that's in good conditon for a good price.

So hey, maybe I'll just try the ca18 t25 and if power cuts off at 5 grand like the other person said, then no biggies as long as it does something at lower rpm range because besides I don't like reving ka's too high past 5 grand anyways.

If anything, you can always save up and swap in a GT28 style turbo and be good to go.

Not to barge into the thread but Im selling all my Turbo KA stuff... I have the manifold a t3 super 60 turbo ( real garrett never used) somewhat of a down pipe with a 02 bung welded in, Also have some ghetto intake piping. THe turbo has an adjustable wastegate? aftermarket?... You would need a walbro pump and an intercooler with piping but other then that you'd be good to go. I also have a stock s13 SMIC if youd want that to. Send me an offer to [email protected] ill send or post up pictures if anyone wants to see them... thanks -Jake

Hey s13 240sx here are some pictureshttp://nissaninfiniticlub.net/...age=1

there are others just do a search for kapower06 in the galleries section... Any ways you will get everything pictured but the pump ( im using it) and the injectors.... But you will also get an Adj. vortech FMU. along with a downpipe and somewhat of an intake pipe. You will need a fuel pump, some pipes and couplers for the I/C and have someone fabricate a pipe to connect the downpipe to the cat. As far as price is concerned im lookin to get what I paid for it which is around $800 total.. You can make an offer but please no low-balling. The turbo itself is worth around $400 . along with the oil lines which include a restrictor and all the neccesary fittings besides the tee for the sending unit. Im using it for my oil pressure gauge. Thanks for lookin -Jake

Yeah you could weld that flange on there, but you may just be better off gettin a t2x. manifold, less hassle, but that turbo will run outta steam a lil early.

all i can get my hands on a really good condition t25 and i'm taking it cuz i know the person and i'm getting a deal.. so how much do you want for that turbo mainfold? how much to ship it to Reading,PA 19606

and for intercooler i already have a frount mount here, so really all i really need to get is the mainfold for now, and the downpipe

Why don't you get the ssac T25 mani, run it with the SR intercooler, but switch out the cold side of the turbo with a T3 .48 or .60. Then you will have the T28, which will feel better. Also, be sure to use the turbo that has the .86 A/R turbine (like the SR, and maybe CA, I don't know). This will provide a little better top end. You can always uprade later, but you will be boosted. What are my credentials? I don't have any, I am not boosted. But I am piecing my setup together, and have often thought of selling all of it to do just that. To make it a T28 you just have to machine a little and find a workable T3 (the most common turbo ever made).

that sounds nice and all Chezedik but i dont have that much money for something like that.. I"m not loaded. I spent cash on a frount mount intercooler of ebay, i can get a deal on a very good condition ca18 t25 turbo from a very good friend i know... that's all i really need, i dont need anything extra to be specail i only wanna run low boost and in the 200rwhp range. Reason why i say it because this will be my first turbo and i never had a turbo car or drove one so i wanna start off cheap, whatever works, start off small just so i can get the idea how things work and things like that, and if i end up poping a motor than I will be okay with that because then I can just do a good rebuild or get a ca18det motor.

That is the cheap route, and good for 200whp at 10psi on just the T25. Getting a second T3 can be done for 70 bones. Oh, and SSAC is SSAutochrome, on ebay. So then why the CA? You will spend good money on less torque with the same turbo.

i dont have money for a t3, and ebay- SSAC i don't think.. i have never in my life seen the ssac on ebay. **** if I find a working t3 for a 100 bucks i'll buy one but I can't so i'm sticking with the ca18 t25 that I can get for 150 bucks and i know there is nothing wrong with it.

I think you are missing my point. First, do an ebay search for '240sx turbo manifold', when you do, you will find a number of manifolds that are very inexpensive and designed for use with the T25 flange. You also will be able to search for downpipes and dumps that way too. Between those three they can be had as a deal for aout 300 bux. That is a really good price. Then whenever you are ready for more power you can upgrade just the compressor side of your turbo to a T3. This is all a T28 is. A T3 compressor ran through a common shaft to a T25 turbine. It allows more airflow with similar response to the T25. This is a very inexpensive way to do it, and there are a few guys on here doing that.

Sorry, apparently the manifolds are only for the DOHC, but I bet you could modify one from the SR to work for you.

You could probably get a flange from JGS Tools to make it work, then weld it. Or they sell everything you need there. By the way, the T3 was used on just about every stock car at some point so they are cheap and easy to find. Look for a turbo GM, Ford, some Chryslers, and Saabs. They are very inexpensive. I got mine from a 300zx. If you do end up using the T25, I will sell you my T3 compressor, since I am upgrading it to T4.
