kade-t vs kae-t

[northstar ninja]

ok. ive decided to do a KA-t, due to many reasons, one being the availability of ka motors, and thier price (over an sr or rb). So the problem ove come to is which ka ahould i build? i have a kae in my car now. Either engine (kade or kae) id build would be a second engine built out of the car to avoid down time. so im asking anyone who knows, is the extra exausy valve worth it? and since the DE is a newer motor , would they be more reliable, especially under boosted conditions?is really apreciate any available input on this one. thanks-g

more flow the better, not saying you couldnt get there on a E but if your going to buy one why not go with more to start

you wont see any major difference between the two. possibly if you're going for 500+rwhp otherwise i would jsut stick with what you got to make things easier fast. if you need assitence you know where i live

[240slidekat]

it shouldnt matter as far as reliabilty because your rebuilding them right? my vote is to stick with the sohc so you dont have to change out all the wiring if you swap. the only thing is you have to search a lil harder for parts for the sohc than the dohc. but yea you wont feel any difference between the two if you boost. its all goin to be the set up thats goin to make a difference.

duuurrr yeah for $200 for a new cam from PDMracing you will be set for the flowz0rs.

[babowc]

welll.. isnt the sohc a little higher in compression? like 9.4:1 or something.. compared to 8.5:1 on the dohc?

correct me if im wrong^^

[toki]

you have it backwards.

all DOHC are 9.5:1, a few early production months of the SOHC were 9.1:1, the rest are 8.6:1

[northstar ninja]

so how would i know id my kae has 9.1:1 or 8.6:1? is there a way to check by vin #s or something klike that?

[northstar ninja]

thanks for the info though.id so tarther do it right once than have to do it all over again.-g

[nismofly]

my main reason for going with the de when i go turbo will be the manifold, theres a lot better manis for the de

[OKCA18DET]

yea and the timing chain on the sohc is a ***** you are more prone to that thing breakin on the sohc then on the dohc (the guide rails)

[northstar ninja]

im looking to get either an apex N1 or gt spec, i was wondering if anyone has any experience with either... id prefer the gt spec, because i believe it has no resonator, so it could flow more, with less restriction... correct me if im wrong...

this may seem like a stupid question, and im pretty sure i can , but can i get a cat back now (im looking at the apenx n1, and gt spec) and when i go turbo, have the dp replace the the header connectiong pipe and cat? i dont want to have to buy things twice, so im just double checking.

example...now:header-> connecting pipe->cat> cat backturbo:turbo manifold->turbo-> downpipe->catback

thanks-g

Yep, you can get any exhaust system you want right now. BRM makes a really good exhaust and they also sponsor NICO. Check them out.

Yup, they do make really nice ones, I have a 3" stainless full catback sittin in my garage right now waiting to be put on once I go turbo.

The only warning tho: if you get something for a turbo (i.e. 3" exhaust or so), it's gonna sound HELLLLLAA LOUUUDDDD on the n/a. And you may lose a lil low-end torque (but that's debatable).

As for how to tell what compression your sohc is:

I second that. Greg @ BRM is AWESOME I would reccomend them to anyone. Build quality is through the roof.

i believe i read a post about the brm exhaust. lots of happy nico members. i just misplaced the name for a while under a pile of other reasearch. but thanks for the site, ill defentally check it out.

also, out of curiousity, why did they make the same motor with two diffrent compression ratios? the hp out put and tq is the same on both right? thanks -g

[northstar ninja]

the brm page for the 240sx exaust dosent work...

Correct me if I am wrong, but I have heard the SOHC KA has no oil squirters , as the DOHC does. This, in my opinion, is a very important thing to consider when going Turbo.

True, the kae doesn't have squirters. But this is really not a big deal. In fact alot of your high hp Honda guys get rid of the squirters. It's no disadvantage to not have them. If you have a kae then stick with it. You can to just as much as the de.

[DRIFTEADOR]

^ where'd you read that??

we add squirters when mating non-vtec blocks to vtec heads to handle the higher revs. i.e., ls/vtec and cr-vtec. getting rid of them increases the risk of oil starvation/spun bearing. what would be the benefits?

[SHIEF]

Didn't read that anywhere.As long as you have a good oiling system, then there is no problem getting oil where it's needed. If you have squirters then that's fine, if you don't that's fine. Either way the engine will be fine.

[2_Liter_Turbo]

I'd rather have them then not. If they are there from the factory, obviously the factory engineers determined the rest of the oiling system to be inefficient. Removing them would be just plain dumb.

[SHIEF]

Oh, I'm not saying remove them if you have them. I'm just saying that the kae w/o squirters will be fine, that's all.

[northstar ninja]

does anyone know this is correct? some one told me that the sohc wont hold more than 8 lbs of boost due to the fact that they are not forged. if so are the kade pistons better, or do i just have to have the engine bored and aftermarket slugs put in?

[Structure240sx]

that will show you the stock kae can handle power. people have also said that the kade cant make much power stock block

im putting together a turbo kit on a sohc right now, let me know if you need my help when u are ready

[northstar ninja]

do you have aim? can i im you?

[nismofly]

Anthony exactly what township do you live in?

im in south jersey at various points between may and august, if you dont mind maybe i could come see your car sometime

[sil80drifter]

Hey I'm rebuilding my SOHC with all stock parts too, expecting to hit 250-300rwhp on them, with good tuning. And by good tuning I mean LiveEdit.Structure, you're not too far away from where I live (like an hour or two) we should uh... do something SOHC-T related one of these days.And swap stories and building experiences etc that pertain to the SOHC.

Also, Jordans bearings are stock, but are the pistons/rods?

Oh and anyone who wants to see what happens to stock ringlands after one week of pinging the crap out of them, AIM me, I have cool pix. In my defense, the ping sounded almost identical to the timing chain rattle, so I only realized it was ping after I did the timing chain job (urgh for the second time) and it didn't go away.
