Calling all ex CA18 & SR20 engine build owners
Moderators: P3g4sus, Daniel, rat, Draco, Riekert
Draco I have a VERY light flywheel and bottom end, on the freeway if I put my foot down it goes, yes it feels slow but the revs just climb. So I dont think it makes you slower just makes you feel slower. Remember a flywheel can only store energy not make it, it also takes energy to speed up the rotationg of it.

Thanks Gary, my point is, although your revs climb and you go....it does not happen as fast as it use to with the normal setup.
There is pro's and con's of this....the pro's and con's are obvious to me and fluffy just stated the same, as for the evidence, my dyno sheet showed a healthy drop in torque, torque is what I felt when I exelirated from an already mooving point, I felt less of this and my speed did not climb as fast as it use too.
From standstill it happend faster....gunning it all the way but it was different when you already mooving and then wanted to exelirate fast.
In the end this is my conclution, for a drag setup, this is a good mod, it beats off some time, for normal use on the road, it sets you back a bit.

Draco I know what you saying.
Because you dont feel the torque that doesnt mean to arent accelerating at the same pace. I drove RBSX (now Weso-sx) S13 and on the freeway I would put my foot down and this thing felt 100 times fast than mine untill I looked down at the speedo. Where I was doing 120km/h in his car I would normally be doing 140km/h in mine (floored it at 100km/h or so). Now although his car feels faster than mine it obviously wasnt. I have no problems with going up hills or anything, I just boost a tad more than what I would have if I had the flywheel supplying my some torque, no biggy.

To each his own, Im just one member of a 300 plus member forum so this is only one members point of view, but I have been specking to Nizan-R and we both have a bit of an Idea.i'm doing yet another sr20det swap.
Is there a Stock swapped S13 with a Red top SR20DET? I know there is a good chance it will have a management system and an Exhaust like Nizan-R we are both wondering what the extra R 7000 buys you down a strip

S13 SR20SET = 151kw - 275nm
Hell the RWD N/A SR20 makes 8kw more than the CA18DET does,,,
I recon R7000 for reliability, ease of parts, 43kw and 64nm isnt a bad deal?
I bet it would cost more than R7000 to get a CA18DET to make stock S13 SR20DET power.

ok... and everybody here talks about ja with lets say R7k you could've done this and that to the CA...
But what you guys don't see here is that some people sell their CA for say R6k and then buy a SR for R7k so they get a power increase by selling the 1.8 for a 2.0. which does kinda make sense....
but ok if you had your CA and R7k then by all means spend it on the CA....
just my 2yen.....

CA18DET = 124 - 129KW and 224nm (depending on which version u got)
And bear in mind most importers now ask a a bout R8500 for the redtop and another R3500 - R3900 for the box. And the CA will sell for about R5k max and maybe R2k max on the box. Usually less for both.

LOL
Yes and I know of a number of worked SR20DE that have a hard time pulling away from a CA18DE powered box sentra down Voortrekker your welcome to come watchHell the RWD N/A SR20 makes 8kw more than the CA18DET does,,,
Look RAW I know you have a hatered for the CA18DET \ CA18DE but thats your opinion, I have stated my point and I have had a number of runs with S14's and I was impressed by the car but not amazed
The challenge still stands guys if you want to see what the deference will be stockish vs stockish hell who has a stockish S14 that would be willing to try Nizan-R

Please Riekert , Most CA18DET don't sell for that amount of cash I know Of at least three people that have picked them up for way cheaper or they don't move and sit in the 4 sale section also you know it wont cost you R7000 to do that Swap I was just being very conservative unless your one lucky guy and get a sweat dealok... and everybody here talks about ja with lets say R7k you could've done this and that to the CA...

Guys do as you feel really Im happy to be part of the club and from what I have learnt and picked up over the years is if a SR20,13B,RB25,RB25 or what ever makes you happy then fine but the little Hated CA18DET is not that bad I love mine

Thats odd, my records show the South African/main land euro late S12 and most S13 run out 4 port as having 108kw... Jap 4 port at 125kw and Jap 8 port at 129kw.Doctor G wrote:uhm....you got your figures heavily mixed up. CA18DET @ 108kw??RAW wrote:

Could be wrong though, was on an origional emissions spec / SABS sheet I was given a few years back, It could be wrong..
Still 125kw to 151kw is 26kw, more than an intercooler and exhaust would give you, which decent ones would set you back pretty close to 7k
Sorry PFB, im not really into watching 14-15 second cars street racing, and no I dont have a hatered of CA18's I just think they are a poor platform to be modifying on... I have built a few 200kw+ CA18's, just anything past 250kw and they are endless money pits.
I mean honestly, anything under 200kw and your going to get flack from most cars quickish cars on the street, to get to 200kw would be a similar price for building a CA or dropping in an SR with a few mods, drive a 200kw SR then a 200kw CA with far less TQ and drivability and youll understand why I say I think its pointless really modding a CA, stock great, but modded...
Maybe an easier way to look at it:
Simple show of how many CA18's here make over 220kw / have run 13.5 or faster? and how many KM's they have on them?
Vs. say, myprodol's car that made 220kw for almost 2 years on the stock SR20 with just some mild mods (before it went

I know you guys are supporting the underdog, I to support the RB25 which is the under dog to the RB26, I feel there are many pro's of the RB25 vs RB26, I just dont understand what pro's you guys see in the CA18 besides the fact its a bit cheaper... initial cost shouldnt really be an issue if your not breaking it though.

S12's came with the ca18et, not det. CA18ET produces 135 hp (99 kW) and 141 lb·ft (183 Nm)RAW wrote:Thats odd, my records show the South African/main land euro late S12 and most S13 run out 4 port as having 108kw...

As for the CA18DET, I love them, especially in NA form the CA18DE's are great little motors. My CA18det went to 160kw (at the fly) after just adding a 3" mandrell bent mild steel exhaust and a cone filter. Everythng else stock. So more than a Sr20DET stock by 10kw.
But, now that I'm in search of more power, I've been looking at all my options. SR came up strong, but bang for buck the RB25 seems like the way to go....
I won't swap out the ca for a sr anymore.
