Hey Dude,

I have a CA18DET in my Onevia. There is no real downfall for the engines apart form the age. They have a cast iron block.

The stadard turbo is alittle small but with a few simple upgrades the engine is good.

I've reco'd mine with forged pistons and have things like FMIC, GT28, 3" and other basic stuff, I'm about to upgrade AFM and injectors and am expecting 200 rwkw. They are a good engine and react well to boost!

I had a ca18 det in a silvia and can't say anything bad about them - in fact I reckon it was faster than my r33 after a few basic mods. Light cars shouldn't be overlooked!

My old R33 was a beast compared to the 180. Have to say that the CA18DET isn't driving to bad at the moment though.

Sydneykid had a post going on a while ago about some of the upgrades you can give a CA18DET; they're a tough engine, having an iron block (like RB's).

With a strong crankshaft (~$1800), and probably some nicer valve springs, you could easily wind the rev-limit up a bit more. Or get a stroker crank, and make it a CA'20'DET. Now we'd be torquing.

my old strawberry face 180 had a CA18DET that put out 174-178rwkw... its basically the same as an RB20DET engine with 2 less pistons :D very responsive in the lower end. Don't get stupid on the engine trying to poke power out of it (if you need a drift pig you don't really need that much power as you do response, which the CA18DET has when tuned properly) and you should be fine.

ca18 is a tuff bit of gear and the only bad thing against this motor is that its a little older now. short stroke desighn (CA18) is a good thing to have in a drift car if you like bouncing your car off the rev limiter as aposed to a SR20 which doesnt like the revs so much but also doesnt need to either.

its a catch 22 but id go the lil CA anyday its a baby 26 in my eyes!

The CA18DET has got a downfall!

When revved high for extended periods the pressure builds and forces the oil to build up in the head and cannot run down into the sump quick enough! This can be blocked off like in a stock rb26 since the RB25 can have to same issue.. when this happens look out number 4 cylinder!

fixes can be to bore out the return lines from the head, and block one of the supplies!

i was wondering if anyone has removed the butterfly from the second inlet valve for each cylinder?

removing that and the shaft that holds them..and bit of a port job... would increase the flow dramatically!!!

oh and could you add a second injector into that valve to run 8 injectors, piggy backed off the same cylinder? seems strange separating them like that!

I have a 1990 Nissan 200sx (uk) with CA18DET they are good little engine but they have massive problems with big end failure no so much the mains.

Turbo is there second biggest problem little T25 don't last long, cheap upgrade to a S14 T28 normaly does the trick.

Rubbish standard WMIC

(just sold my 48k mile CA and bought a RB20DET (32k miles) much better ) :P

I have a CA with only a few bolt on mods and it beats stock SR 20s. I have had it for over a year and havnt had any troubles at all.

Does anyone know where I can get a Apexi Power FC for my CA 18det. Im in Tassie and just wondering if they come pre tuned for the engine? R they hard to install does anyone know. Thanx

Apexi Power FC's are easy to install and come with a basic tune.. but for best performance you would need to get them tuned!

you can get em online or from a performance shop.. autobahn have some but ridiculously overpriced..

checkout greenline or Nengun!

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
