Ca18det FAQ

[DeBastaard]

Don't know if it's been posted before, but you can:
- Use a Z32 fuel filter
- Use CA18DE Intake Cam for some more torgue

Edit:

Cheap/Easy upgrade:

- You can use the FMIC from a Volvo 740 Turbo, or a Saab 9000 2.4 Turbo instead of the standard WMIC.



Oh btw,

I Live in the netherlands, and all S13's here come with CA18DET Standard, so if you guys have any questions at all don't hesitate to pm me!
I'll browse thru the FAQ tomorrow and if there's anything missing i'll post it here

DE intake cam is a myth. There is no power increase.

[sLiDewAys]

i concur.


but some claim +15 when use both intake/exhaust? maybe another myth?

[DeBastaard]

There's a slight increase of torque when using the ca18de intake cam. Changing the exhaust cam has no use...

[sLiDewAys]

lets talk about common turbo sizes used for moderate power.

A real basic upgrade for the ca18 is the oem sr20det retop turbo. believe it is a ar.64 but some clain ar.80? i highly doubt it is but lets talk facts about this turbo and its potential on the ca serries engines.

It has been said that 230'ish wheel hp is achievable with this turbo on ca18 engine on SAFE boost levels(12psi). max on it is 15 so you can see why i stated SAFE.

Suporting mods consist of;
full exhaust/bolt ons
intake
fmic
and adequate bov
boost controller/wastegate

also i wanted to get an idea of everyones set up here on this ca18 faq. so state what you are running and what problems you had for instalation, weather using ca parts or sr parts. ALSO, i'm asking if everyone who posts here can provide any dyno results with pics if possible.


thanks,
brandon

SR T25 = .64 A/R turbine housing .80 A/R compressor housing.
S14/15 T28 = .64 A/R turbine housing .60 A/R T04B compressor housing

I think 230whp is possible with the SR T25. I'll let you all know when I put my motor in. I'll be using the SR T25 as my "break-in" turbo. My power related mods will be--

CP forged pistons
fmic
3" exhaust
Z32 MAF
450cc injectors
eprom

[DeBastaard]

You can use a T28BB from a S15...
That with the FMIC, Freeflow exhaust, Cold Air Intake, 1bar boost and a chip gets you 270-280hp here. You can go higher with bigger injectors (Nismo 555's) and a Z32 AFM. Above 300hp it's just a matter of time before your CA18DET breaks... (with stock internals that is).

I'm going to be running Saab FMIC, 1bar boost, freeflow exhaust, cold air intake) And i'll be having 230bhp and about 330nM torque. (This with a "Stage 1" chip from a well known mapper in europe).

We don't use Power Commanders over here that often, buying a pre-mapped chip is way easier haha

[liv2drift045]

i never hit the dyno but my set up WAS as follows (oil pump died)

original setup
stock turbine @ 12psi
stock ex manifold
3" greddy ca dp
test pipe
apexi n1 dual
turbo xs single stage mbc
autometer boost gauge
ssac fmic w/ custom hot and cold piping
s14 greddy cold pipe

it died right after new turbo setup
ssac manifold, dump pipe, 1piece dp+test pipe
s14 bb turbo @ stock boost (felt just as quick as the stock turbine @ 12psi NICE)

[DeBastaard]

You can run 1bar with that setup dude, no worries

[boosteds13]

Not with stock injectors. 370cc injectors hit 95% duty cycle at 240hp @ 15psi @ 43.5psi base pressure. He would need at least some 450cc injectors and possibly more. You need 550cc injectors to fully take advantage of an S14/15 T28. 450's max out at ~275hp @ 15psi and 43.5 base pressure. I would never run my injectors over 90% duty cycle.

[DeBastaard]

Ah shit yeah, I've just read the website of the guy who mapped the chips again.
He says don't go above 14psi. 17psi is doable with 444cc's...

[sLiDewAys]

nice set'ups guys. Has anyone tried the GTiR pulsar t28 on the ca18? i know its a much larger trim than the s14 models.

but here was my most recent set up.

sr. t25g
hks 12 psi wastegate
ssac manifold
ssac 02 dump
ssac downpipe
ssac FMIC kit
greddy type s bov
blitz intake
stock managment


and this will be the up to date setup once i put the engine back together

HKS gt2510 turbo
hks boost controller
mines VX-rom ecu
z32 MAF
ssac manifold
ssac 02 dump
ssac downpipe
ssac fmic
PROF sheep dog BOV
Blitz intake

ecu was programmed for stock injectors and was rated at 240 wheel hp with supporting mods. once i get 550's im hoping to put near 300.

[idiot goes sideways]

i dont know how much my ca18det 180sx make, but i don`t have big problems
to beat my friend`s ford sierra cosworth rwd, the old 3 door one.

i`ve no idea how well know`n cosworth is in US,
but it`s a 2litre 16valve turbo (without catalysator and 200hp at stock) and tuned to 400-600 hp is no big problem, ive you got the money.

like i said i can beat him, with these mods
ssac fmic kit
ssac engine back exhaust
power fc
intake
misc. suspension upgrade
STOCK TURBO (maybe i can $ change to a bigger one this spring)
STOCK INJECTORS
and other litle things

AND YES HIS DAMN COSWORTH IS STOCK!!!!!!

GTi-R Turbo's fit, but you need to rotate the intakeflange from what i've heard

The trims are all the same. The difference is the size in the turbine housing. The GTiR turbine housing is a 0.86 A/R which would be quite laggy on the CA. What you can do is swap the .64 housing from the SR turbo onto the T28 and you have yourself an S14 non-ball bearing T28. But like Debastaard said, I think the compressor housing needs to be rotated slightly.

Im finishing the process of rebuilding a CA18DET. Some mods i have done. Port Polish
Aluminun Pulleys
Flywheel reduced in weight and balanced
Manual boost controller - Turbo XS
Apexi SAFC II - black edition
GTi R T28 Turbo
GTiR 440cc Inyectors
Exedy Stage II clutch
Greddy Type R BOV
Front Mounted Intercooler and stainless steel pipes.
HKS FCD
3'' Exhaust System
3'' HKS muffler
Throtle Body with better capacity (wider)
Double Fans supporting th water pump for cooling

The main problem it has been placing the new turbo, you have to rotate the position of the original T25 and build a new Downpipe. It is also highly recommended that you seal the exhaust manifold with bronze seal.I havent drive the car yet, its coming out this thursday, and the tests will begin.
My only question is, which could be a safe PSI setting for this engine... I mean does someone know how many PSI can a stock CA18DET engine stand?

Forgot...sorry for my english
Best Regards

[sLiDewAys]

to your question about safe boost levels on a ca18det's bottom end i cannot answer correctly. i have heard 18, i have heard 20. but i will further investigate the truth out of this question for you and post a posotive reply on it, i will also explain why and why not...

[Shri222]

my contributon from what I did. No i'm not a newb I can't log into my old account



my ride too

[DeBastaard]

Most people here do 17psi on their stock engine, above 300bhp the stock ca18 can break down...

[racer20]

OK over all is the ca18det cheaper then the sr20det. I am looking into doing one...

[sLiDewAys]

so look into it. nicoclub.com is knawlegable, so is nissansilvia.com. anywhere else you will jsut get the usual SR owner cocky remarks. some are cool enough to hold a decent thread on CA. but nico is your best buy.


any questions y ou have you can always pm me or email me. if anyone has \any questions feel free to call my cell

[shane_lxi]

earlier someone posted that you should get rid of the secondary charcole cannister. This can be wired into the engine harness when modifying it to fit. If you get rid of the canister, you will have less low end torque.

[ChinaManDrift]

WooP WoOp 831 aKumA DoRi... ....Blackman i got it workin .....i can post on zilvia ......sorry imma ae86 owner zilvia noob .......why is an ae86 owner on zilvia you ask .....cuz dis ae86 gonna be power by ca18det........wEeEeEeEe...

i know the USDM Nissan Pulsar's have a CA18DE in them and some of the negatives about a CA18DET are they are aged and high mileage. Out of curiosity, are the internals the same with the USDM CA18DE motors as the CA18DET?

[eswop]

A lot of us in Norway drive with these mods:

in addition to the list below i would add an Oil Cooler and rebuild the bottom end...

check out:

http://www.horsham-developments.co.uk/

The stage 3 chip is designed to optimise the fuelling and ignition for an S13 with the following modifications:
Free flow air filter
Free flow exhaust
17psi boost pressure
Uprated intercooler
T28 hybrid turbo
Uprated fuel pump
444cc injectors
Z32 AFM

The chip removes the fuel cut and, in conjunction with the upgrades above, will allow the engine to produce in excess of 300bhp.
The stage 3 chip will only work with 444cc injectors and a Z32 (300ZX) air flow meter (AFM).

A power graph will be posted shortly. I have had one power run with the chip and achieved 300bhp but this was in extremely high ambient temperature (>40 degrees C!!) - I will be obtaining another power graph with more sensible ambient temps.

No, the FWD motor does not have a crank girdle. Also, the pistons in the USDM ca18 were a higher compression ratio and did not have piston oil squirters. All the internal gaskets are the same though if you were looking to do a rebuild on a ca18det.

[mikesim]

i just wanted to point out that CA injectors are Peak and Hold (low impedance), not Saturated (high impedance), as stated on page one. when you're looking for RX-7 injectors, its a big deal, because they have both peak and hold and saturated over different model years.

the chart is correct for the years and colors i think though.

[sLiDewAys]

leaving the ca world guys. its been a nice journey. ca has taken and proven to me and also to other thats its not as crazzy as everyone thinks. still available for questions if anyone has any. my ca is going into my crewmates ae86 now

300hp corolla? WHAT?? lmao

[liv2drift045]

that sucks slideways... i had to leave too... it was good having you knowledge tho, i learned al0t from the info u took the time to put on ca faq board

300hp hachi would be nasty lol

[boosteds13]

It's alright boys, mine is going in this weekend... wOOt!

Here she lies--
