ca18det drifter

[sdtouge]

the ca has the least displacement of the kat, sr, and ca so if it is the lightest (not sure if it is) would that make a 50/50 weight disrtibution possible. also wich engine would be the most relaible 280-300 whp dd and 375-450 on race gas. thanks in advance.

I'm not sure about reliability, but im pretty sure that the sr is lighter than the ca because it has an aluminum block while the ca has an iron block.

I don't know if anyone's weighed the CA, but the SR and the KA are about the same weight rolling in at about 500lbs. The SR is primarily aluminum while the KA is mostly iron, yet they are about the same weight. If you're talking about getting a 50/50 weight distribution, on a coupe, move the battery to the rear, use a carbon hood, and use the silvia front end. That'll get you very close to 50/50. Ditto with the fastback.

at 280-300, I'd go with KAT or SR. They're both able to hit that pretty easily and pretty reliably. At 375-450, the KA in terms of reliability because of one thing. When you start approaching those numbers, the SR's bottom end is approaching the limits of what it can handle. Yes I've heard about the Enjuku SR, but not all motors are going to be the same in terms of the condition of the bottom end. The reason why I say the KA, you would have achieved those limits before you would on the SR. You would already have needed to replace the bottom end before hitting those numbers. That's why I'd say the KA is more reliable at those numbers.

Where do you get your info comic books. The sr will take 400 even 500 on a almost stock bottom end. What the pro's from japan aint doing above 300. I know guys in Japan with just bolt on mods hitting 350 to 360 and have been running their sr's with absulutly no trouble.

Also the Ca is a cast block it wheighs more than the SR. And swaping 240 and japan sheet metal wont drop any wheight. What is this fasination with 50/50 weight. A little front heavy is better hell you think Kuroi is worried about 50/50 he rocks a rb26.

You are quite right about the SR. But the fixed Silvia headlights are much lighter than the pop ups. and the the fastback is lighter with better weight distribution than the coupe, and with the silvia conversion, the fast back is even closer to 50/50 distribution. And weight distribution is very important, but with an RB26, there so much power it doesen't matter about balance, because the RB can haul that heavy *Censored**Censored**Censored* around turns easily.

BTW, just because it has smaller displacement does not mean that the engine itself is smaller or lighter. By no means, it can mean several things.

Depending on the crank to rod length ratio, you can have a very happy revving engine or a stroker with tons of torque but super unreliable on the topend. Alot of engine building shops will refuse to stroke a motor that is already good.

BTW, if you bore out the motor, you're going to lighten your motor because you just lost some mass inside your engine wall.

I know nothing about the CA18, but I'm just letting you know the common missconception.

CA18DET are great for under 300 goals. Above that they need head studs and a head gasket. They are awesome little motors that rev great. KA-T is the best way to 400 that i can think of.

How many people here have done rebuilds on the CA18DET, SR20DE and SR20DET, KA (sohc and dohc), and an RB20? *raises hand* I've seen alot of different condition motors. Most likely you've never considered that two USED condition motors may not be the same on the inside. Just cuz the pro's are running 400 on the stock bottom end doesn't mean that they haven't torn the motor down, inspected and repaired as necessary. Keep in mind that most guys stateside will get their hands only on USED motors. Which usually means 'sold as is' aka no warranty. You've no idea how hard those motors have been beat up while in Japan, I was lucky I got a good clip with a good condition parts. A few other locals though weren't so lucky when I tore down their motors. The 3S-GTE I'm currently rebuilding now was seized, his pistons were scored from valves hitting it and as a rebuilder, I was pretty po'ed that someone sold him that motor in that crappy a condition, but it happens. So by all means, go ahead take any motor you find, and go ahead and try to build up massive amounts of power and see how long it lasts. A key word in the first post was reliability, now if you're talking about making 4 passes on the 1/4 mile and having your motor rebuilt then it's not too much of an issue, but some guys here (myself included) have our cars as daily drivers aka reliability is very crucial to us (especially if you've a job or go to school and have an exam to take) so why don't you take a step back and think about it a bit more eh?

Also from what it looks like, you've never tried lifting the headlight motors for the flip ups compared to the fixed headlights. I can tell you I have, and there's quite a difference. ~44lbs difference when you change to the silvia fixed headlights from the flip up light assembly. Yet another reason why front ends tend to lift up a bit when you put the silvia front end on stock shocks/springs, cuz they're spec'ed for something a bit heavier.

A bit of info for engines, just because a sheet of aluminum weighs less than a sheet of iron, doesn't mean that's the way it is for motors. There's a thing called fatigue all metals go through, iron handles it alot better than aluminum does. Aluminum builds it up even though the stress has been taken off it, iron dumps the stress. As a result, aluminum blocks/heads tend to be bigger and over engineered as a result of that fundamental weakness. Yeah it's lighter if it's cast the same way, but if they're two differnt motors, yeah you've got something else to weigh in.

LAPD, looks like you've been reading too many initial d comics and need to get your head out of those comic book drifts.

This is very true... Aluminum doesn't have a predictable tensile pattern as does most other materials. Aluminum actually is known to have a very erratic curve. Therefore, it has to be overengineered with several factors of safety to cope with the amount of stress that comes about in a motor.

Most of the other materials that are used in car engines are very predictable. Anyways, just because a motor has six cylinders doesn't mean it's heavy either...

Next time, check the specs of the motor before saying which one is heavier. You can destroke a 3.0L motor to a 2.5L motor that revs like a champ. Or you can take a 5.0L muscle engine and stroke it into a 5.5L torquey beast... In both cases, weight of the motor did not change significantly. But the characteristics of the motor did change.

huh? What does this have to do with anything?

ROFL... I say go with SR20DET and put on the Disco Potato (Jim Wolf Technology/Garrett's T28 Turbo)... This is a very powerful setup from what I hear and understand.

Comic books eh I was drifting before you were out of daipers. I was on this site before you saw your first ID manga. Ive been building these cars in japan for over 12 years now PUD WISTLE. DO you know who I am yet.

IM DX and ya better ask some body Biatch

i knew you were dx!!!! now with the ca18det how much are they goin for anyways????

That's quite a shock to the system eh? Our old pal DX knows his stuff, take a gander:

yarichin4u: DX

Look dude, you were goin off on me first. Fine so you know veilside guys that's cool. But you I've not seen any numbers on the CA's weight. People were askin bout the weight of the CA. Also just because you're 'DX' doesn't change fatigue characteristics of metals. You made the assumption that just because the CA is cast iron, that it'd be heavier than an SR. could be true, might not be. I've never seen conclusive numbers on the matter, hell it was the first line! Get your veilside boys to put em on scales and take pictures if you're so chummy with em. Might as well be a use to the Nissan community instead of letting your ego run sky high.

#2 just cuz some other guys do it, don't mean all can (run high power on stock bottom end). You can't just make a broad generalization like that. It's like to say all cars that are of the same line are made the same. They're not, some come out of the factory as lemons and some don't. Come around sale time of the used cars, some were taken better care of than others. Condition of the motor is pretty important and if you're as knowledgable about motors as you say you are, you should know that. Also remember that the motors stateside are all used motors from clips. I doubt any of the veilside guys use used motors in their current form from a junkyard, but the motors that come over this side have been in accidents, have motor troubles, etc. Aka not necessarily the best basis to build a racing motor on (given retaining the stock bottom end in it's current condition). So just cuz you know about drifting and know some guys at veilside still don't mean *Censored**Censored**Censored**Censored* if you jump to conclusions without supporting numbers/evidence or numbers/evidence that are available to the general public stateside (since this board has quite a few stateside users).

To address your last comment about drifting, I never said I was an amazing drifter. You again jumped to a conclusion. Maybe I was mistaken thinking it was directed at me, but it was in the text body and assumed it was directed at me.

[NismoSigma]

LOL he is trying to reconcile! ahhaha .... ok ok ima be the adult here. Stop you guys, you both obviously know what your talking about, so stfu. I think everyone learned something new here and thats the purpose of this. Please say sorry and stop instigating a little forum's thread. Poor Sdtouge all he wanted was a simple response to his question and you guys and blew it outta proportion. IF you guys are older act your age, your a bad example to all the young drifters!

To be honest with you, I don't see where he was trying to reconcile. If he was then yeah sorry to have taken it the wrong way, but from what it sounded like with calling me a "pud wistle" and this and that, it didn't quite sound that way to me.

NismoSigma you are right though bout SDTouge's situation. Sorry bout that Sdtouge but at least you got some more info...then again maybe not necessarily on the CA that couldda helped you out more on your decision.

[Parry]

hahahahahaha oh man, tryin to tell DX what's up when it comes to buildin motors. holy crap, what a riot.

You still have no idea who he is do you?

[NismoSigma]

I dont but he seems to have done his homework to say the least. He prob got banned if he is using another name.... right?

Don't matter who he is. Hell it could be Dori Dori himself. It's like saying go ahead and build a high hp motor on a stock bottom end. Yeah it'll probably run, but it becomes a matter of how long. Stock stuff don't handle high numbers well for long. To just go about saying willy nilly that you can build high numbers and sustain it for 3 or 4 years on a stock bottom end is absolutely ridiculous if you're shooting for reliability. That's just common sense and honestly if you're not thinking about it but just taking his word for it, you can go ahead and try it. Go ahead and build a 400-500 hp machine on a stock bottom end and go to work, school and this and that. See how long you can keep it up as a daily driver. Even the Enjuku drag 180 doesn't see much action, it's mostly a dyno queen and if you think it gets ridden in every day rolling out the 550-560 hp it's putting out you've honestly got something else coming to you. Sorry to put a damper on the indestructable image the SR seems to have to some of you guys but as well built as it is, it's not going to take a beating of 400-500 daily and last long. That's just either 1. sheer stupidity or 2. absolute ignorance.

By all means go ahead build your motors around the stock bottom ends and push for the 400-500 hp and see how long your daily driver lasts. But when your motors start to fail, it won't be the motors fault.

[s14driftingTX]

The SR is 44 pounds heavier than the CA. I know the whole aluminum is lighter... well if you've seen the thickness of the aluminum on the SR block, you'd believe the CA is lighter. I've been looking into this swap and seriously thinking about it, I just wonder how hard it is to find replacement parts for it. If anyone knows about this PM me or post it.
