intresting Ca article, dont know how factual it is ..

opinions?


Nissan CA18DET

Fun Fakt- The CA18DET engine was the first engine to power the Nissan 180SX and Silvia in the S13 chassis. A few were used in some of the FF cars, like the Nissan Bluebird U12. With only a limited production run in Japan from 1989 thru mid-year 1991. With a cast iron block and a max horsepower rating of 175 in the factory setting, the CA18DET was assisted by a single ceramic bearing T25 turbine utilizing a Garrett housing and internal wastegate. The factory setting did not require a blow-off valve, unlike its predecessor, the SR20DET. Charge air was cooled using a tiny side mount intercooler. When compared to the SR20DET, of the two, the CA18DET is capable of handling more horsepower without a lot of complicated rework due in part to the cast iron block. Even today, the engine of choice is the CA18DET when drag racing an S13 and S14 in Japan. It's not uncommon to see a CA18DET unleashing 1000+ hp. SR20DET cannot claim such numbers. If someone says they are making that, tell them to show the proof. The edge that the SR has over the CA is the fact that the SR had a longer production run. Parts are plentiful and much cheaper compared to the CA. This is the reason that Japanese usually opt to swap out a CA for an SR. CA's can be had for very little money in Japan. - Dale
CA18DET Engine Parts 180SX FAKTORY recommends TOMEI POWERED for all of your CA18DET needs. Why? Quite simply- they've been in the game for the CA18DET ever since the inception of it from Nissan back in 1989. They've built winning cars powered by the CA18DET, and they don't regard the CA as some "second class" citizen compared to the SR, because they know the CA is a very lethal engine when built right. Lastly, 180SX FAKTORY uses TOMEI POWERED parts in Black Sunshine, specifically the 1.2mm metal head gasket and the PON-CAM intake 256 and exhaust 256 normal lift series.

thnks , just thought i would throw a tech. article in for a change lol.


need opinions?

i like the idea of doing a ca swap and if this article is true then it might be a good choice
?

but cant tell if article is written to sell their ca build kits.

 

i honistly think that if the ca was a better engine than the sr then there would be more of a demand for the ca. in turn there would be more promotions for it and more companies making parts for them.. just my 2 cent.. good find though

 

yea

cast iron block ftw

 

the ca like the article said wasnt produced as much as the sr.. its a great motor.. low displacement.. thats the only downfall.. in my opinion ka-t is the way to go in 240s.. then i like the ca just for low cost of swap.. then sr.. mainly because ka-t is CHEAP and easy build and if you build right it can be fast and if you put the same money into turbocharging a ka that you do for sr swap it can be made faster.. and a ca swap is extremely cheap compared to both of them.. iron block is amazing for holding power.. i dont know much about the rest of the motor tho.. its a good swap if your looking for that kind of thing

 

Stock sleeved SR's have cleared 600whp. The amount of work to make an SR handle 1000 whp after 600whp has been attained is minimal in both time spent and money spent in going up another 400hp. Simple things like turbo choice, fuel choice, and machine work differentiate the two.

Having an Iron block does not immediately allow more horsepower capability out of the bat.

In fact, I know a few people PERSONALLY who have attempted to build CA's to handle even 500 whp, and had nothing but problems with them over and over again, specifically regarding the bottom end oiling, and clearances DUE to the iron block. One of them was Paul Souder. If you don't know him, you never will.


Show some proof please. Every drag racer I've ever watched videos of from japan is either SR or RB swapped.

It's not common PERIOD to see a CA18DET of any kind running around. There's not enough left. Please, provide proof of one even running over 500whp lol. and not a webpage yahoo japan from 1992 either, hahaha.

ok.





I beg to differ. On the main Tomei website.

The Official TOMEI Web Site --> tomeiusa.com

SR is front and center in the engines page.

CA is only listed in small font under "other engines".

sorry. just here to disspell the myths. It's a nicely written article by an obvious CA partisan.

Having worked with both plenty I can tell you I enjoy the reliability, performance, and engineering behind the SR much more.

And before you go around saying that CA's have a better valvetrain, the fucking things have hydraulic lifters also.

 

take it from someone that's been there almost 10 years ago.. when the majority of you guys were still looking twoards pizza fridays in elementary school..... I was asembling my first E6K harness for my CA and Matt was making like 1298123471320947 ft lbs of torque on his VG30E and taking down MKIV supras at Desoto on video like it was cool....
CA = not for noobs... Power is possible with extreme knowledge and skill.. and a lot of luck. Mine made 587 hp @ 9800 rpm... but it was constantly breaking things.

SR will do this and be reliable.

and sponsor repped for bringing actual "tech" talk to the forum lol

 

It is pointless to build a CA18DET for large power output, unless your trying to make a point, or be different. The KA24DE, having an iron block, will produce much more horsepower and torque due to the larger displacement, if built properly. However, an SR20DET will make the power these two motors output while providing reliability that the other two can't hold a candle to.
