New to CA's

[rps13srsc]

Hi guys i have had a few sr's but never a ca i am looking to put one in my coupe for a daily driver maybe 200-220 rwhp

i also have a stock r34 gtr turbo available to me would like what yall think about this turboand any advice for a new ca guy would be greatly apreciated

i have heard alot of good things about ca's for a dd and would like to do this swap

ive been on nico a while but when it comes to ca's im a

let me the first! to wecome ya here to our humble ca section on nico

200-220whp is a good number to shoot for and shouldn't require much work. Is that skyline turbo a T28 or T25? Cause you will be very hard pressed to see 220whp from ur average T25. Not impossible, just unlikely.

Most CA parts are easily attainable from either N13 pulsars or S12 200sx' at local parts stores, just check the faqs for parts that interchange.

Feel free to browse them faqs with any questions you have

its a t28 being that it is off of a rb26 it has a small exhaust side it is designed for half of the motor (1.3L) i can get the numbers off the turbo in the morning

i was wondering what supporting mods i would need to run it such as injectors ect.

i plan to put in a fmic during the install along with a down pipe and exhaust and a manifold and probly a profec b any other mod advice would be helpfull

sry just relized that i didnt sign in under my account im at a buddys house and forgot i was under his account

I dont think that turbo will bolt up to the O2 housing/dump pipe. I would either rebuild an SR T25 or get a used SR T28.

the RB26 turbo's are tiny. Smaller than a t2 from an s12 I'm told by a good friend who's compared them.

RB flanges are also very different and hard to fit to a CA or SR.

I love the way a T28 from an s14 SR works on a CA. it's an excellent match with the right mapping

thanks for the advice and keep it coming i want to do this rite its my dd and i want reliable

[rps13srsc]

Here are some pics of the t28 gtr turbo with the a/r showing if anyone knows the specs on the ca t25 please compare them for me and post them if you get time.

Doesn't look like it'll bolt up. Problem being that the CA exhaust manifold uses studs, and so does your turbo. Also, its tiny. I think its even smaller than the stock CA turbo.

The SR T25 would be a good match for your goals. Also remember fuel pump, injectors (440's), and full exhaust. An intake wouldn't hurt either. The stock MAFS will probably be OK, but you may want to get an N60.

[Two-Fortee]

Intake, 3" exhuast, Front mount, your T28 (should work fine, even though I'd go for one off an s14 or s15 if money wasn't an option) Boost controller maybe set around 8-9psi and I don't see why you shouldnt be over 200whp , if not, then very close.

If im in the wrong here let me know, Im faiirrrly new to ca's, but this is what info I have gathered on them

Long live the ca18det !

Welcome aboard.

That turbo he's got wont do 200whp at 8/9 psi. It MIGHT get there at 15, but if that's a skyline turbo, it's got inconel turbine blade and you have to be real careful turning up the boost on those as I've heard they like to come apart at higher shaft speeds and temps.

[rps13srsc]

yea the gtr turbo is only good for about 220 at 15lbs but your right it can come apartthanks guys i hope to find a ca very soon

OVERKILL!!!!! 370cc injectors and standard MAF will be fine with a T28 at 14psi let alone a T25g. And yes, I've done it SAFELY many many times

[float_6969]

A CA with 370cc injectors at 100% duty cycle with 36psi static fuel pressure and assuming a BSFC of .55lbs/hp/hr is only going to support 233 BHP.

A T28 at 14psi on a CA is making way more than 233 BHP.

The only variables that I assumed were the BSFC and the fuel pressure. The fuel pressure is the stock fuel pressure that Nissan uses. If you've added an adjustable regulator and increased the pressure, then this calculation is off. It's also generally accepted that turbocharged motors are between .5-.6 BSFC.

To reach the accepted safe limit of 80% duty cycle on the injectors at 233 BHP, the BSFC of the motor would have to be .44, which is VERY low for a turbocharged motor. I've never heard of it anyway.

If you're truly running a T28 at 14psi on an otherwise stock fuel system and ECU, you HAVE to be at the limit of the injectors or the turbo is not flowing the CFM's it should at that level. If a T28 is only making 230 HP at the crank at 14psi on a CA, there is something wrong with the turbo.

If what you say is true, there has to be another variable...
