CA18DET build with ARP studs update!

Post by **boost_boy** » Sat Jul 12, 2003 3:23 am

Hey Guys,

I started assembling the motor yesterday evening and so far the ARP hardware looks promising, thanks to "CA19DET" for scrounging up part #'s and sharing them with us! You can also use the KA24DE's ARP head bolts on the CA. I tried them yesterday and they are about 2-4mm longer, but everything else is the same. Today I'm going toput on the headgasket and head to verify that indeed the head bolts are perfect. The Pauter rods' clearance in the CA is tighter than the factory rods. I'm going to run the motor without it's timing cover because of the adjustable cam gears and accessibility. I'll leave you boys with some pics, but I'll get back with the results. We just may be in the big league after all

oh by the way :drooling

Big problems with these bolts; our head design doesn't allow a socket to fit into the wells of the headbolt base thus preventing the tightening of the nut. I took out the ARP studs and replaced them with my brand new stock headbolts and 2 staged the torque sequence on the Nismo 1.2mm headgasket. I got clearance between the valves and the pistons, so my biggest worry is over.

how come no one else has an oil cooler on there motors but i do???

Post by **cortina-mk1** » Sat Jul 12, 2003 3:23 am

from our experience i would not choose to run the engine without the timing cover.. boost_boy

the reason being is that the crank angle sensor alignment will be comprimised because the lack a stable and secure base to be tightened to.try and remove as much as possible while still leaving as many bolts to keeps it secure.

what may happen is it will break the aligment pin on the end of the camshaft.

slw240sx,we will be running a grex oil cooler on the engine this coming season.

he wont have to worry about the CAS alignment, because he isnt using a CAS. He is using an SDS Stand alone that eliminates it

what do you think about the nismo head gasket? i was thinking of getting one since i get factory stuff for so cheap now! whats the quality/cost/etc. will i really need it over a stock one?

i did a search and it seems they are a hall effect trigger to be used with ECUs you use in the states...

autronic SMS or SM2s use the exsisting crank trigger unit

Cortina, did you go to http://www.sdsefi.com That is their website. All the info you could possibly need there also alot of good info too! I love that site!

no i didnt ...thanx her is the ECU system i use on my car

i have a factory oil cooler noone else does that ive come across.

Post by **USDM_OneVia** » Sat Jul 12, 2003 3:23 am

I don't have one either.... I thought they only came on the Euro spec CA's.

slw, as far as I knew, they all had them. I could be wrong though. In the FSM that I have of the CA (I got it of zilvia.net) it shows it has having one. where is yours located?

I'm pretty sure you are wrong!;)

but seriously the FSM you have (and everyone that has an english one has) is the European one! so yes it will have an oil cooler shown...

It's made of 3 metal sheets (2 thin ones and a thick sanwhiched in between the 2 smaller ones). Also had to stop assembly yesterday because of a cracked rear main oil seal housing and that really sucked. Went to my favorite junkyard today and got one off my old CA16DE motor that's been there since 1997. And "cortina-mk1", I gave up on the factory stuff after I had a bad experience with my girlfriend's car not responding to boost. I mean it would rev out, but would not get too excited when it came to boost (even when I pulled the hose off the wastegate and let over boost). I had been reading up on standalone engine managment systems and concluded that the SDS system is more to my liking because of the use of a hand held programmer as opposed to a lap top. Simple, easy to tune and gets the job done plus;).

The real question is, is it an effecient oil cooler? Has anyone measured the temperature drop across it? will be purchasing my CA at the begining of August. I'll check to see if I've got one, and if so, I'll measure it so we all have that info. Maybe boost boy could do it since he's got his torn down.

Post by **slw240sx** » Sat Jul 12, 2003 3:23 am

my oil cooler looks like the one in the FSM. its on the oil filter assembly plate that goes to the block its round and has a water in and out. it sprung a leak so i got real fimiliar with it !

Quote »it sprung a leak so i got real fimiliar with it ![/quote] Not fun was it?;). Quote »The real question is, is it an effecient oil cooler?[/quote] It does the job and quite well may I add. I've always used it and haven't had any burn oil issues. I've had cooling issues once upon a time, but never harmed my engine's oils. I use Lucas oil stabilizer in my engines to keep the viscosity up to par in my engines incase of emergency and it works just fine. I'm going to continue using the water-cooled oil filter housing because it's never let me down.

Post by **CA19DET** » Sat Jul 12, 2003 3:23 am

i'm thinking of running an external oil cooler with the OE simple oil cooler,

hey boost_boy, looks good...

keep us posted.

just take a socket and get it machined to fit in the head bast to tighten the nuts for the fasteners, don;t sacrifice sealing and peace of mind for a couple bucks worth of machine work, thats just going to eb your special head bolt socket

thats what i did and thats what my engine builder does for his 4g63 too..

hope that helped,

heya nd what you doing with that datsun 510 in the background of the engine pic #1

slw240sx, where did yours leak ? no water and oil mixing, huh ?some threads on uk forums regarding leaking oil/water coolers.... enough to cause some concern. Anybody use a sandwich plate and a remote conventional air/oil cooler. I wonder if that lil oil pump can keep up.The 90 DSM used such a cooler, stock. Later 91 & up DSMers ditch their oil/water coolers and retrofit the 90 unit

I still have them in the box, but maybe it's because I'm using the 6 point nuts instead of the 12 point ones. Oh yeah, be wary of the crank studs as one towards the rear main oil seal will not clear the oil pan without some massaging of the oil pan with a hammer and even then the oil pan distorted a bit.Quote »heya nd what you doing with that datsun 510 in the background of the engine pic #1[/quote] That's a customer's car that's getting some work via a boosted KA24. I'll keep the bolts around for the next round because I've already stretched the new bolts and they torqued perfectly. Here's a pic of what that 510 got going on:

thats the factory oil cooler we have them here also....

what engines are these KA's you talk about ? never heard of them here..

Post by **CA18Fastback** » Sat Jul 12, 2003 3:23 am

the KA engine series was in the US and Canada only, if i remember correctly. Early (89-90) 240sx's came with an SOHC KA24E w/ 140hp. The later (91-98) 240sx's came with a DOHC KA24DE w/155hp. It is often swapped out in favor of the SR20, RB, or CA, as it is considered a "truck engine" due to its appearance in many early Nissan Pick-ups. It is very torquey but lacks the rev-ability of the lower displacement I4's from Nissan. FWD versions also appeared in the Altima and Sentra/200sx.

If anyone else can add to that, please feel free.
