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!

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
