Hey CA18GUY, look here!!! q's on ca18

[240meowth]

as i've read from previous posts, the ca18 is an iron block compaired to the sr20, which has an aluminum block.  thus, you should be able to put more boost on the ca18 right?  how much boost can you put on the stock internals? and how many hp and torque can you get out of the stock internals.

p.s. after i read ca18guy's post, i think i'm going for ca18 when i have money <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I know for a from experience that they can last to about 380HP without any internal mods. My friend had one back in Japan and I used to go out to the races with him and and would run about 1.2K of boost(I have no clue how much that is in standard measurement. Does anyone out there have a conversion chart?) All we did was put a aftermarket metal headgasket(1.2mm) from TOMEI,swapped cams, used a Lancer EVO4 intercooler, upgraded the injectors and fuel pump with stock GTR ones. installed an aftermarket fuel pressure regulator, added a Z32 AFM, and had the ecu changed out with a one from a SR silvia and rewritten for the CA(s13 ecu's are 8bit and the PS13 ecu's are 16 bit). I'm not sure which one but the turbo installed was either a to4e or an t04s. The stock redline is about 7500rpm but we used to run it to 8000rpm with no problem at all. Of course, we also changed out the intake and exhaust. everthing in the block was stock and everythink in the head other than the cams were stock. I'm pretty sure the potential for the ca18 is higher. If you get a ca18DET in the states it might be a good idea to look into upgrading it to a ca20det. You can take the ca20e engine out of the the s12(the '88 200sx) and the twin cam head head on the ca18 would bolt right on. You have to use the crank pulley and timing belt from the ca18. You can set the timing for a stock ca18det and that would work fine infact if you can get the twin cam harness and ecu, if my memory serves me correct you can used that without even having it rewritten. Only thing is you don't want to go over the stock revlimit of the CA20 because of its longer stroke. The reason I know this is that in Japan tuner shops re-import ca20's from other countries to upgrade their ca18's( they don't use ca20 in japan that I know of and if they did its hard as #### to get one because I've never and noone I know have heard of any car with one). &nbsp;Also, &nbsp;if you need stock ca18 parts there is a datsun truck out there somewhere that uses the CA18DE engine so you can get stock parts like the timing belt(very important) in the states. Hope you have lots of patience, time, and money because I don't think there are alot of places that work on the CA's in the states. I know a guy in Okinawa that threw a L28 in his silvia and that thing was mean as ####.

i saw a guy in australia that transplanted a ca20e crank into his ca18det and fabricated a twin turbo system (should've stayed single). the thing im wondering about is, how much hp will the CA20E N/A block actually take? you'd need forged internals if you wanted to see anything near the power the ca18det could make stock. if i was gonna do some sort of swap into a US s12 i'd just go for the FJ20ET, i've heard they can take a 500hp build

[ca18guy]

I could'nt tell you exact boost levels. On a stock Turbo It would be 16-18 psi, upgraded turbo would be 20-22 psi ussually. Remember though it's not the how much boost but how much air your turbo flows. Stock internals could probably handle 350+ HP this is with upgraded injectors/racing head gasket.

err not quite right. Datsun trucks(620's) here in the states used L18's in 1973 after that they switched to L20B's . 721's next generation up used L20B's then switched to NapsZ series engines. Hardbody trucks started out with NapsZ engines in 2.4 liter in 1987 in 1990 they switched to KA24E. the rest is history.
Pulsar NX SE in 1987-1989 used the CA16DE and yes you can use the timing belt from it for your CA18DET

[ca18guy]

S12's had the ca18et but i dunno how many parts you could us off of it.

IS the ca18 still in production?

[240meowth]

so w/ a simple upgrade of the fuel injector and head gasget, maybe turbo i can pull 350? &nbsp;'cause me and my friend wants to go the track, and that foo has a BMW m3, i'd look pretty bad w/ ka, or pretty much, anything. &nbsp;so i want to know wha i can pull outta the CA and the torque on the CA

I could've swore that there was a car that used the CA18DE in the states. &nbsp;The reason I'm saying this when I rebuilt the engine in mine a few years back I used a chilton manual from the states for all the specs and torque setting. &nbsp;Maybe I was looking at the one for the CA16 and didn't even realize it. &nbsp;If you can use the ca20 crank in the ca18 block with the the pistons from the ca18det that would be a pretty cool setup I think. &nbsp;It would be different from the typical sr swaps that everyones starting to do overhere in the states.

[240meowth]

wouldn't it b nice if you just stick w/ ca18 instead of ca20? &nbsp;w/ the ca18 you can rev higher!!! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

If you want any kind of power from a CA18DET you'd have to swap out the turbo because tell you the truth the stock turbos on those things are crap. &nbsp;I don't think you can get over 250hp with the stock turbo without the turbo blowing on you.

[LanceS13]

I believe 240hp is a reasonably safe limit for the stock T25 turbo...which isn't bad--240hp is a good bit for a 2800lb. car. &nbsp;I think a T28 should last you to around 300-320 w/o much turbo lag. &nbsp;More than that and you'd probably go to a T3/T4

Nope. &nbsp;For the person that said the stock turbo is crap, there right. It's the same turbo you would get on a Red Top SR (T-25)

Woah. No there is more to it then that to getting to 350 HP. Read my post (which it seems u did) I go over alot of things (looking back I missed some things, i wrote a novel, I could'nt include EVERY little thing) &nbsp;BTW for a real daily driven set up you would probably want internals if u go all the way to 350 HP. &nbsp;Also I can't think of one car in the states that has the CA18DET but there are cars with the CA18ET

[junia]

the turbo on the PS13(redtop) is a t-25/to4b turbo and is better than the one on the ca but still if you're going to upgrade the turbo, get some power, and want street driveable car without having to swap cams and all, I would suggest a turbo off of either the s14, the s15, or the pulsar gti-r. &nbsp; They are ball bearing turbos and they give you a good flat torque curve and have a little punch. &nbsp;I think they're rated up to about 280-300hp. &nbsp;I drove my friends ca with a t04 and also another friend with a sr with a td06-20g turbo installed and I didn't have any trouble driving it on the street. &nbsp;You really don't have to worry about driveability untill you start throwing on a T67's or T78's on a 1.8 or 2.0 litre engine.

Just to clear things up a bit...the car in the US and canada that came with a CA18DE was the 1988 pulsar (N14) IT was in a FF configuartion....so yes...timing belts are a simply local auto parts store away and some sensors would swap...I think.

To get 200hp out of a CA18DET is as simple as a intake, exhaust, and manual boost controller away...although I would recommend an intercooler right away...cause once you hit 10 psi on the stock T25, you will be blowing nice hot air out of it...

With the intercoller maybe 210-220...???

At that point you will be running faster than most street cars...at 300 hp level you need to get a new headgasket (metal) and then at 350 hp plus...headbolts stretch and possibly better internals. *shrugs*

But at the 300-350 hp level...you'll be damn quick anyways...

HEHEH...I was searching and found it...when I saw the wrong info..I felt the need to correct it...*shrugs*

for the man that revives year old dead threads.. and quote...[Just to clear things up a bit...the car in the US and canada that came with a CA18DE was the 1988 pulsar (N14)]

maybe in canada but in the U.S. the 88 pulsar had a CA16de . now stop reviving old dead threads.

Pssst heres alittle secret, the stock PSI is 10 !!!!! This topic is closed, its just top old to leave open. To correct myself in this thread, the ca does have the same turbo as redtop SR but had a different A/R, so it pretty much isn't the same turbo :D
