Hello. I have an a31 cefiro but since I am in Turkey we have a CA20S engine. I did some research. Then I found that I can swap with a ca18 but when I heard that it has the similar substructure as the s13. I thought I can swap with an sr20 because the sr20 was used with the s13. So can I easily swap the sr20 on my cefiro or is it difficult?

Yes, it will fit, with the right engine mounts, plus a complete wiring loom. The CA is carby fed, yes? Then you need to add a complete EFI pump system (probably a whole tank) to get that to go.

I don't know the 4 cyl stuff that well, but I'd be reasonably sure you'd need an SR gearbox, which will definitely need a clutch, and probably lead to needing tailshaft mods (although maybe you'll get lucky there).

There will be more. Not from me. Just on the list.

yes easily doable was very common conversion around 15+ years ago

Require:
Sr20 cross member and engine mounts
sr20 gearbox or bell housing if manual CA already
sr20 loom and ecu
sr20 radiator (or make a cross over pipe to us CA style radiator)
sr20 engine

All parts can be sourced from an s13

Will require some mods to engine loom to body loom plugs but plenty of info out there on that.

RB20DET also came in the Cefiro and will sound a lot better than any SR20.

Can go up to RB25/RB20 if you want it to go faster than SR20

I would do it but the spare parts for the engine are either not available or very expensive so I'm thinking of going with SR20

RB20 being an option from factory would mean no custom parts or fabrication required, just have to collect the right bits. Probably would be the easiest option I reckon for a motor swap. How common are SR20s vs RBs in Turkey?

I would suggest equally difficult to find, perhaps edging to the SR. Turkey has almost exclusively Euro market cars, some Korean, few Japanese other than pedestrian shite. I guess they're probably losing the fight against Chinese shit like we are now too.

I would vote for a BMW V8, found in a 540i in a wrecking yard somewhere in Deutschland (or possibly Albania).

SR20s came with cars like the Bluebird and Primera, but the RB20 never came. The ones in Turkey were either brought in specially or from abroad. That's why RBs aren't as common as SRs. And if a part breaks or I need to replace it when doing maintenance, it's harder to find parts for RBs.

I asked someone about this and he told me about the Audi 1.8T engine. But I think it would be difficult to swap

FWD is different though.

I would think that rather than attempting to perform an engine swap, with all the difficulties associated with doing so in a country where the raw materials required are harder to get hold of, I would just build the CA20 for boost, find an EFI manifold for it and either add a turbo or a supercharger. Or both.

You replace one set of difficulties with a different set, but I know which would be more fun.

If there's nothing else I can do I'll probably do something like that

Someone on the internet said that ca20s and ca18 engine blocks are the same and that you can use a ca20 engine block and put ca18det parts to make a ca20det Do you think this is possible or will it damage the engine?

Given you already have the engine cross member to match and likely gearbox mount to. The SR20 has a head start on the RB in this case.

They handle GREAT with an SR20, lots of fun.

 

One I did back in the day

I hope one day I can do it like you. Your engine looks great.

I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy.

Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.

    • Dear folks My family members have 4 different cars : Triton 2015 and Corolla 2011 and Mazda3 2012 and Hyundai Elantra 2014 Looking to buy engine oil funnel spill free What I found are are below  https://www.amazon.com/gp/aw/d/B0BBTTJNKX?ref=ppx_pt2_mob_b_prod_image&th=1 https://www.ebay.com.au/itm/145553221359?srsltid=AfmBOoqYBU6Ptw0LU_bAp_k67U3qkF97HHvePkA7iHZw8vUmiwoIRaRr https://www.amazon.com/gp/product/B09X23TCS5?th=1 Is there a funnel with attachment that fits most cars ? Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
