n/a ca18de

[ca18datsun510]

well once again i have recently gotten renewed interest in my 510. but to keep the cost down and hopefully finally get it running, ive decided to ditch the turbo set up until a brighter day.

anybody have, or know where to find info on the jdm ca18de?

[float_6969]

Why don't you just put a regular exhaust manifold on you CA18DET?

[c-rad]

lol, I did that once on my DSM. My turbo was SHOT so I just disconnected the wastegate arm. It took me almost 30 seconds to reach 70mph when merging onto the highway. 7.8:1 compression and no boost = no acceleration. I doubt 8.5:1 would make much of an improvement...

[float_6969]

I think it'd make more than you think. The compression on a CA18DE is only 9.5:1

[ca18datsun510]

well, i dont have a na manifold/header, and i was gonna maybe build the turbo motor.

and that ca18de with rwd trans on ebay is only about 45 minutes away from me.

[c-rad]

Ahh my bad. I thought he was saying just putting an NA manifold on his DET. Nevermind then, I am an idiot....

[NeedCAforS13]

I have a rwd n/a manifold taking up space in my garage... i'll trade you turbo manifold for n/a if you'd like

[ca18datsun510]

is it that header that you had a while back, or a stock manifold?

[NeedCAforS13]

stock exhaust manifold... tms had the header, not me

I just aquired another but it's cracked, needs to welded up.

[ca18datsun510]

how much, shipped to 10509

this is to themadscientist, and sean

[themadscientist]

You in the states?

[ca18datsun510]

yup yup

[themadscientist]

It ain't that heavy, $125 shipped would cover the postage and put some gas in my car.

[ca18datsun510]

the motor set im getting comes with a stock manifold, so im gonna see how well that fits before i go for the header.

nobody has info on these engines? i dont want anything crazy, just something reliable and cheaper then a turbo.

[fanta]

What will you be doing with the turbo motor? What was left before startup anyhow?

[themadscientist]

what info do you need? I have the CA18 FSM as well as the S13 Silvia FSM.

[ca18datsun510]

the turbo motor is going to be going in my s13, or in the 510 later on. as far as startup, i needed wiring, new turbo, fuel pump setup, turbo exhaust housing-muffle, intercooler piping,.... the list goes on.

as far as info for the na motor, im just looking for any small power upgrades and such. i plan on beating on it, so i want to know what it can handle, and what i can do to make it take more abuse.

[themadscientist]

watch your oil pressure. Every time a CA takes a dump it seems to be #1 con rod. Mine was getting ready to go by the look of the bearing. In it's defence that is a year of abuse at my merciless hands; 8500rpm shift points at full steam.

A header, 55-60mm ID muffler and an SAFC should yeild some gains. You will have NO torque though, I reccomend rolling starts. You should be able to play with KA-powered 240s of the same level of tune.

[ca18datsun510]

well its going in a 510, 1900 pounds of fury. give or take a few pounds since its pretty well gutted, but will have a cage in it. and as far as the safc, i was planning on a standalone. sds setup.

[ca18datsun510]

madsci, any way you can send me the wiring diagrams from the fsm. the ones that i would need to wire the enine into the chassis.

do you have them online?

thanks a lot.

[themadscientist]

I failed to notice that, in a featherweight 510 you should have good pep. Raise the compression with a 0.6mm head gasket or flycut the head it should be a hot mill for the 510. the manual is in Japanese, don't know if it will be much help. I can list the computer pinouts for you though, I have translated those.

[float_6969]

TMS, If you could please email the JDM FSM pinout to me so that I can put in the FAQ, or if you want to put it in there that would work too.

If its a rwd ca, the ecu pinout is the same as the rwd det, just missing the turbo associated stuff, which is not a lot anyway.

To make a N/A DE go good, you need to fit a 60mm throttle body and get the manifold ground out to suit. These T/Bs come on N/A auto sr20de and not much else in the states i think, Oh yea, also on fwd u12 ka24e

Get the compression up to 10.5, run a set of headers, rb20det injectors, they are same high impedance, but 10cc's bigger, give the fpr a tap on the back with a 3/8 extension to increase the fuel pressure.

You can also run a fwd u12 ka24e afm as it is a little bigger. I dont know if the s13 ka24e has the same afm. You have to muck with the wireing as the ka afm is 3 wire and the ca is 4 wire.

Get the cams reground, and advance the intake cam.

That will give your datto a good boost.I have a mate in new zealand that had the same setup, 5 speed s13 box, r200 lsd, shocks/springs/17's and it went like a rocket

[ca18datsun510]

whats the stock compression? anyone?

[themadscientist]

9.5:1
