Well Im a Noob looking at getting a 180sx and I come across that there are 2 different engines in them. The CA18DET and the SR20DET.

I was wondering if someone could tell me what the real difference is in these engines. I know one is 1.8 litre and the other is 2.0 litre but what is the difference between performance and reliability?

If someone could help me out it would be great.

From my experience, if you want reliability go with the SR20 version, everyone i know whos had a CA18 one the engine has died. SR is an all alloy engine & CA is cast iron block. SR performs heaps better and easily tuned for more power. CA18 are really quick & revvy when in good condition, but i think their age is the biggest problem.

mate, go to nissansilvia.com, thats is the silvia and 180sx club site.

go the sr20, it is much more advanced, the engine is more reliable, quicker, punchier, easier to get parts for, the list goes on.

also the sr model is the later model, with better suspension, braking, and interior.

ive done alot of work to a mates sr 180sx, its pulling 244rwkw with a gtrs turbo and a few other bits and pieces.

the power is like an on off switch, 4000rpm, the wheels just light up. nothing like my 33, which has a broad torque range.

cheers

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
