help!! ca16de 2 ca18de

[Tey]

i've got a 1987 exa with a CA16de engine which needs replacing. i was hoping to replace it with a CA18de engine but i wasn't sure if this was possible.

The mechanic i saw said that he could put the CA18de straight into my car without changing gearbox, computer or anything.

Is this true? Can I put a CA18de engine into a CA16de EXA?

[Tey]

ok, so it looks like no one knows the answer to that so i'm gonna stick to the ca16de and my mechanic has suggested that he opens my current engine up and replaces the piston rings and cylinders.

problem is that my car drives rough and blows lots of smoke, and i mean lots.

[NismoPlsr]

i supose it is possible to keep the ca16de tranny in there but thats bout it, here is what i recomend doing

ca18de ull need
tranny
axles
clutch pedal
master, slave and hydraoulic lines for clutch
of course a new ca18de clutch
tranny mount
rear engine/trenny mount
CA18DE ecu and harness

if u wanted to use the stock ca16de ecu i think u could but u would need some kind of piggyback comp to give more fuel seeing how it has greater displacement

[dirtrace49]

Yes you can replace the ca16de with the ca18de. It is a direct replacement engine. They are the same engines. the only diff. is the displacement of them . The ca16de has a smaller output then the ca18de. I'd go with the ca18de. If you were to go with the ca18det engine, that is a entirely differnt set up due to the T_ for turbo.:flashsmil :flashsmil :flashsmil

wow this is a olde thread! i was 12 when it was created! ok so all i will need is a ca18de hopefully outa a exa an swap engine, gearbox, ecu , over? thanxs in advance :)

I researched A LOT into swapping a 1.6 with a 1.8. It isn't that easy. If you're going to that effort, you might as well get a different engine. Find another decent FWD engine if you'r spending that money.

But, I know where you can get a 1.6 if you need it.

[holdenboi]

well im looking at a 87 exa with a ca16 in it an was wondering if its a eazy conversion or not figured it would be almost same engine rite?

[StaTiK]

small things need to be changed. driver side cv shaft, injector plugs need to be changed, and a few other fiddly fuckers of problems... i havent done that conversion in about 3 years now, so its a bit hard to remember.. Most of it is straight forward, and its not a hard swap to do..

tatty, either you dont know much mechanical, or your blowing out your ass champ.. its easy ;)

I was looking at a RWD 1.6, my bad. IMO I still don't believe it's a really straight forward engine swap, there nothing like a straight swap.

fuk all to it just bolt all the ca16 shit to the ca18 and put it in lol
To make up for fuel use a fuel pressure reg and up the pressure a tad

[StaTiK]

or dont connect the vac line to the FPR... will give a 1psi increase in fuel pressure.

[StaTiK]

oh oh oh!!! cv shafts will be fine, BUT you need to change the cv joint support bracket on the back of the motor to fit it.

It isn't that straight forward. You will find problems.

[ty_exa]

afraid it IS that simple mate. stop talkin shit if u dont know or have the experience.... i have done this conversion alongside statik too another members exa.... engine bolts straight in. swap the c.v. shaft mount on the drivers side. gearbox etc bolts straight up too new engine.

injector plugs are different, so u can either swap looms, or splice new injector plugs onto it. and swap ecu's (although will run with the ca16de ecu).



EASY CONVERSION... do it in a weekend if u got a couple mates too help out

[SIK__M8]

dude its easy as if u treat me like a dumb ass i have done all my own conversions i know wat to do

Just use the ca16 injectors they work fine

[tatty000]

From what I've seen I believe it isn't easy. I was looking at a RWD engine though, but as far as I'm concerned from looking at slapping at 1.6 to a 1.8...

Either way, it's up to him to whatever he wants to do.

[holdenboi]

Thanks peoples! but the decision is still 50/50 by the looks so might stick with the ca16 for now im picking the car up Saturday so we will see in the future i reckon :bounce: but thanks for the heads up guys appreciated

ca16de to ca18de is fine i have done 1 of these conversions this year for a mate only issue i had was 2 different types of cas sensors one will make the car run like crap at operating temp. other than that if you can undo nuts bolts and hoses you wont have a problem pm me if ya need some more info when changing it.

[spoon]

do the conversion... i have an 87 that had a ca16de (as they all did) and now has a ca18de.. i also have an 88 that was factory fitted with a ca18de and seriously, the wiring harness is different, so just swap a few sensors and shit from the ca16de to the ca18de as you notice the plugs dont fit..

[Edwards]

my parts car is an 87 and it had a ca18de, still had the 1.6 intake so the loom still matched up etc, it did only need cv support bearing bracket to work, never had mine running properly but different displacement and severe loss of compression dont go too well together i think. As far as the swap goes the block casting is pretty much identical so all engine mounts and whatnot are fine, ca16 gearbox bolts strait up no worries. obiously you'll have to use the ca16 starter as well. as for the injectors i cant see why you cant use the ca18 plenum and use the ca16 throttle cos the TPS has an extra plug on it for the ca18, and as for the injectors you might just simply be able to remove the dropping resistor and bridge certins wires to complete the circuit.

Honestly it really isnt that hard, the simple worry free way would be to get a ca18 ecu and wiring harness and you'll have no doubts what so ever. as for that CAS thing mentioned above, i'm pretty sure the CAS are all the same, so if it runs like ass when it heats up you've got a fucked CAS.

thanxs guys great help im keen on doing it now as iv burnt out my clutch an 3rd gear is pretty much goneeee so might be doing it soon just need to save :( but just wondering if i do most of the work my self how much am i looking at but ill be getting an auto electrician to do the ecu wiring thnks in advance guy big help

ps do u know where i can get any nissanexa.com stickers?

[fever]

dude in all honesty why don't you buy a car someone is selling here for cheap then you fix it by yourself.. look in the FOR SLAE section .. you will save heaps more .. believe me when i did my conversion from DET to de it cost me roughly $2000 to get the engine , loom, ecu and gearbox, including the mechanic charges.. if you can get a car for cheaper it'll be better.. go on car sales aswell and have a look..

fuck it im going ca18de all the way looking at some motors now so this is my summer project :D hopefully on the road be4 feburary when i leave

[StaTiK]

you cant add dropping resistors or whatever Edwards, you can use the CA18 mani, but you need to put CA16 injectors in. no point swapping TPS if your going to run CA16 ECU. where the second plug going to go? ;) The issue with the injectors is the plugs themselves. they dont fit, without umm.... modification with pliers/side cutters... ;)

fastest way to do it:
get the ca18de. swap over all CA16 gear onto CA18. ie, intake mani, gearbox, CV support bracket, etc. drop her in, wire her up, off you go..

danspd, i have never come across that problem. ive fitted many cam angle sensors to both CA16DE, CA18DE/T engines and all are fine.

tatty, to fit a S13 CA18DE, you have to swap over all the shit from the CA16 to the CA18, such as alternator, ps pump, engine mounts, cv supports, cyl head oil drain, etc.. basically you are only using the bare block. if you want to use S13 intake manifold, you need to make a new plate for the intake manifold(unless you find a U12 style end plate), with a line tapped in for the brake master, swap the throttle body with the end plate, new intake piping to go to the stock position (if wanted..) and wire in different plugs for the injectors. or modify existing plugs. you can use a section of the S13 cooling hoses too to clean the engine bay up..

the 1st time i did it, it took me half a day to set the motor up properly. its a peice of piss..

[holdenboi]

cheers StaTiK still trying to find a engine but iv got a job now so that helps ha ha i am going to go the full lot gearbox to hydro, an wire in a new loom for the ecu. so how much am i up for boys if i do it all myself?
