CA engines?

Hey Im saving for a CA soon. And I was wondering what kind of RPM can these engines be taken up to… and what RPMs can they be taken up to when internals are done up. What would one have to do perticularly to this engine to have it reliable at 10k+ Is it possible?. Ive heard you can take these up to 8k stock. so I was thinking 10k would be a realistic goal for this small motor like this one. Does anyone know of any engine that have these types of rpm capabilities.

hahaha, 10,000 rpm won’t be reliable man. if you really want that for some reason then buy a bike.

why do you care so much about what rpm your engine will do, but have made no mention of power?

being realistic to get a CA up to 10K you will need somthing like a Tomie High Rev kit and prolly other high quality internals. So if your prepaired for a full engine tear down and rebuild with some fancy parts. There was a guy in st. catharines named Kevin who had a really amazing CA in a 180sx he imported I am pretty sure the specs were as follows from what he told me.

Tomie High Rev Kit
Tomie 2.0L CA Kit
(these replace your pistons, rods, valve springs ect ect)
Garret T70 turbo
Injector upgrade (cant remember now)
Fule lines and rails upgraded with a walboro fule pump
Apexi Power FC

Guys from niagara might remember this car it was grey, had a full nismo gear set too. Basicly as you can see to get that power you need either alot of cash to do it right or a hookup on parts.

Yea the engine is going to be torn apart, its going to be a side project for another year or so, I dont mean reliable as taking it to 10k for day to day driving, when the engine needs to be pushed like on the track i dont want to tear apart. I didn’t say any hp ratings because once you can get a well built engine that you will be able to take up to those RPM reliably… torque will come after.

thanks s14_240sx

Even if you do build an engine that can handle 10K rpm then you’ll start running into transmission issues.

Not to rain on your parade but I would scrap that idea and build an engine that will have a good powerband, 10K isnt going to make it faster by any means and if you think you can track a car with that rev range and not have to tear it apart regularly your kidding yourself.

Therefore you should just jump on the new wave and do the LS1 swap, rock 400HP, sound badass and it will be reliable lol.

I love my CA and they are great engines but 10k rpm for a regular driver isn’t exactly easy or practical.

Solid lifters, cams which will be worthless below 7000rpm… strong valve springs… rods… pistons… better cooling… studs… new bearings… sodium filled exhaust valves…

It’s a LOT of money and what you’ll have is a race engine which is completely useless on the street.

Honda can pull off the high rpm power with low-rpm response thanks to VTEC and the fact that they can switch between a low-lift short duration low-rpm profile and a high lift, long duration high-rpm profile. You won’t have that luxury so you’ll be stuck with a race profile cam that totally kills low-end power. If you don’t go that route then you’ll lose VE well before your 10,000rpm goal making that engine speed useless.

Unfortunately you can’t have your cake and eat it too.

If you JUST want the power for the track and not regular driving then yes it can be done.
The stroke is ‘short’ so the piston speed won’t be crazy but it will still be high and you’ll have a lot of wear as a result. Expect to rebuild a lot.

10,000 rpm + daily driver = useless.

GT

10,000rpm for a daily driver = baller

Just because it will be capable of 10k rpm doesnt mean its going to be doing it when its being driven daily.

You ask for advice and then don’t listen to any of it.
I don’t see how your 10k rpm CA will be a great daily driver.
The cost of making this engine of yours will vastly outweight what you will get in the end.
Go look on www.nicoclub.com ca18det forums, learn something about the engine.
Going on what you ‘hear’ and then forming your own conclusion on no real basis doesn’t work.

Relax yourself Im listening to everyones opinion. thats why i asked the question but im also giving my opinions, i dont mind when people tell me im wrong That how we learn. Ive been on that site and ive read countless hours about them Im trying to find out more info. This car is going to be my daily driver… but there is also a possibilty that i will get another car as a daily and this will be strictly for the track. and FYI i didnt ask for advice on what i should do with my car and its purpose I asked what i should do with an engine to have it perform a certain way, S14_240sx,KoukiS14 and nocwage gave me answer i was looking for + their own opinions which Im definetly taking into consideration dont you worry about that.

So…you assume and say
“You ask for advice and then don’t listen to any of it.
I don’t see how your 10k rpm CA will be a great daily driver.”

I like what you said tho, kinda sounds like you at the moment
“Going on what you ‘hear’ and then forming your own conclusion on no real basis doesn’t work.”

The fact is that you asked about reliability and going over 10,000RPM in the same sentence.

Mike answered that part of your question and, having owned a CA, he speaks from experience - not from internet forum bullshit.

Getting an engine to run at 10,000rpm and not blow itself up, let alone be useable on the street, takes knowledge, skill, and money. (Or just a shit ton of money…)

If you don’t happen to have these 3 things (or the 4th thing), then maybe you should start with something less ridiculous and something that’s actually realistic.

here we go again.

Call a machine shop and find out how much ballancing, knife-edgeing the crank will cost, you’ll need upgraded cams, upgraded valves, springs, retainers. A complete head job so the motor could actually flow air that high instead of just being a gian restriction. If you’ve got that much money, to do this, then you wont be using factory hg, studs, or internals or ecu.

Estimate $10000-15000 minimum for that motor budd and it wont last. Race motors like that need constant attention, they dont run for years and years.

Bottom line, if you want an 10000rpm motor keep watchin initial D.

Ask kouki s14 the cost of the 4ag they just published in modified that revs to 11000rpm. If you’ve got that type of cash and driving an s13 you’ve got issues.
