I currently have a nissan 180sx with a ca18det. I also have a near complete sr20det in my garage.
I’ve been contemplating swapping the sr20det in to the 180.
Here’s the pro’s and con’s of each that I can think of…
ca18det:
Pro’s: 41000 original km’s, very clean motor, and pull’s very hard. Also the motor is already in the car so no work needed.
Cons: a bit harder to make power on and parts availablity has already proven to be a major headache.
sr20det:
pro’s: easier to make power and source parts for. motor is already in my posession so ti would not have to be puirchased or ordered.
cons: motor hasn’t been fired for about 7-8 months which kinda worries me. aprts would be needed such as a fuel rail and injectors, and the swap would need to be done which = time and money.
I’ve also considered the following…
ive tried to sell the sr20det for months now with little luck.
i may have more luck trying to sell a ca18det with a spare tranny due to motor being proven, clean, and strong.
I should also mention that im not looking for huge power numbers. I have decided I would be satisfied with 220-240 hp. As of late, power has not been my interest.
Since the CA18DET is already in there… you might as well keep it. Try to sell the SR for cheap maybe… and then use that money on a GT28RS and maybe some injectors and a MAF. And I think you’ll have a pretty nice setup there.
yes an SR is better than a CA… CA is pretty much poo… but its already in there, its got low mileage, there are no problems with it.
get an SR turbo or maybe a GT28R and stick that on there with some bigger injectors and an SAFC or something simple and make it a bit faster… other than that… just chill.
as someone already posted, parts can be bought locally for cheap, the internals are solid, and face it, it’s a 4-cylinder RB. i’m prepping one right now for my S14. should be in around april, hopefully.
ever cross-reference the head internals between the CA18 and the RB26? valvetrain is the same i believe.
besides, you don’t need big power for big drift. take it from this guy.
S13 running a CA18DET. standard injectors, standard AFM, Apexi turbo, 180rwkw (241hp).
errr, what the hell am i saying. it’s a piece of shit, sell it to me for cheap. i could use a spare. 8)
Don’t forget CA chassis cars are more than 100 pounds lighter than ours and come with a shorter final gear. Only two things that makes it driveable, which A LOT of people over look.
If your goals are 220 - 240 hp stick with the CA, after that it’s like running in sand.
As you will notice, most people who hype CAs are people who have yet to have one and realise their mistake.
In your situation no, you have a lighter car, the better rear diff, and you only want to make 220 - 240 hp which wont be hard. I would stick with the CA. Also the SR you have looks tired.
