full out ca (680hp)

[euroboy]

hey guys,

well after some time i decided i am going full out on the ca.Before i just go around and buying parts i need to do homework.Since i am researching i might as well post it here as well since many of you have gone through many steps .Goal(high but...) about 680rwhp

rpm 10500I need to know how much the head stock flows, what cams i should use, what pistons rodsif i should change the crank(do something to it for sure)what turbo would work well at what psi?

anything you can throw my way would be great. In the mean time i am reading dee's and other's work and it's helping. The more the better

Budget(as much as it takes)

I can count the 700hp CAs on one hand, lower your goals. Unless you are a shop and have truly unlimited funds and expertise and just want to prove a point lower you HP expectations or get an RB26. You are far ahead of the game from the start if you really want the power you expressed. The CA can do it but it will be riding the razors-edge, one weak injector away from becoming a Claymore mine.

well that' the point...I already am going with the rb swap on my other car...I am going full out, and ike i said budget as long as it takesgoal will not be lowered...It will either get done or me dead while trying!Any info?

Heres a good example of what you might want to do. 632ps ca18 silvia

I would be amazed to see a 10.5k CA on any crank let alone a stock one.

But if you have the cash, then anything is possible.

Good luck.

Rummor has it a shop in my area called hasslegren has made a 4AGE that rev's to 12K for some guy with a 86. They also build formula atlantic motors for toyota so its a very possible rummor. I plan on having them do my head work when the time comes.

Heres a pix of one of their 4AGE's

Sexy.... Dry sump... itb's... nice.

The 4AGE really is an amazing motor...

What I would do with unlimited funds:find the best local (or not so local) machine shop and have the port the hell out of the head and put in the biggest valves possible.Grab the biggest cams you can - 270 duration 10+mm lift, and springsSolid lifters.Custom fab a slightly shorter stroke crankCustom fab rodsForged pistonsDry sump oil systemmotec ecu1600cc injectorsProbally a T76-sized turboquaife sequential 6 speed

and put this in a Lotus 7.

Did. According to a supplier of Tomei and JUN parts that I know, both companies officially stopped production on CA parts and are selling off all of the old stock. So now you need to get custom work done or buy used.

yeah many ppl will find this a bit funny.The reason why this was posted here was not for other members to tell me good luck it can't be done!I am not here to post to win someone's sympathy. I was asking for information if someone had them handy!The crank will most likely be a one off steel crack treated balanced, rods and pistons obviously aftermarket.I need to know how much the stock head flow so i know what to port. Every NUT and BOLT will be changed and the whole block will be machined after measuring and remeasuring many times.Now my request to you guys will be if you PLEASE can share some information if you have any. If not then thanks anyhows. I know i will do this with or without someof you help. To those who actually took the time to actually write something productive THANK you!To the rest, you don't know how much i know and what i can do with this engine. If you think you are god?! That's fine i am not trying to get your crown i just want to build a CA18det the way I WANT to!ThanksBess

You know man, most people in this forum are very helpful, but if most think rationally, one would have to ask, how do you all of a sudden wake up and say you want to go all out on a motor you have very little knowledge of. I mean, in order to begin achieving your very achievable goal, you must first do your own research and I mean thoroughly. If you really have that kind of loot to toss off like that, why don't you just buy an already assembled Japanese variant and go from there. But if you're the hard-core type and want to wear the crown of being your own engine builder, you still need to do your own research. No one's really gonna spoon feed you information that's already published on the net, so don't start with the talk about people being gods and taking of crowns because with that type of attitude, you won't get any help at all and then you can truly wear your own crown.

BoroBoroS13 had a link in his post for you, which would definitely point you in the right direction. Why don't you click on it and read to see how much effort went into making a truly venerable CA18. Oh yeah, to my understanding, the displacement has been changed, so I guess it's no longer a CA18, now is it!

I don't mind helping anyone with achieving their goals because I'm not selfish and I don't need to justify my unselfishness. Themadscientist's post is not to discourage you, but it's putting it to you in real time. If you're trying to prove a point or go for the fame, then in order to completely claim the fame, you need to chose your own path and study as you walk it.

So don't get upset because you're not getting the information you want. if you look around this forum and at many of the posts, most people are just trying to get their CAs to run right speaking of which, did you ever get yours to run right? Your quest is not impossible, but it ain't easy and all the answers you need are not in anyone's brain housing group on this forum.

I'm not being a d!ck, but merely telling it like it is.

well since you had the bitter reply i guess something i said hit the nerve with you. My attitude? There wasn't/isn't any at all. I said thanks to everyone who gave me some valuable info.

Now to set something clear...My motor did run! It run great until the turbo gave up!

'one would have to ask, how do you all of a sudden wake up and say you want to go all out on a motor you have very little knowledge of.'

You know franky you don't know me and i don't know you. I give you respect at what you do from what i hear. Just because i don't post dyno pulls and 1/4 times and you know nothing what i have done doesn't really give you the right to sum up my knowledge about the engine.But if you see it that way then i am not gonna argue and try to PROVE to anyone what i have done in my life. It's not my style.OBVIOUSLY research is needed and i am doing my homework. But since i couldn't find the flow of the head (i could find the flow of the intake) but that can't help me much.I have been reading for the past month over and over the whole fsm and reading diff topics on how much is one making what mods done to it. And no i do not prefer to be spoonfed since i am already more than capable of eating on my own!

You know as i said before i was never trying to proove anything at all. If you read my post it says the engine I wanna BUILD for my own. I don't care if a 2jz will eat be or rb will dust me. I simply don't care. Again, you are taking it a bit personal since whatever i may have said hit your nerve or something. Well i wasn't trying to be rude.I was asking for INFO and "have fun" isn't info at all. But since according to you i don't know about this engine i should try and look it up the "have fun" is some integral part of this motor!

read again i said THANK YOU to everyone with information wether i have read it before or it's new stuff i appreciate that someone took the time to write something to HELP...Have fun and go RB aren't help!But i guess you think of some of us are very stupid and we are not worthy of trying something like this?!well at least now i know that you think i know jack about this motor.... it's funny how you know ppl's capability just like that.Sorry i don't have a dyno pull but they don't make you a great man!!!!I am not here to argue but to learn so if you have anything to add please email it to me [email protected] i would be happy to talk to you in private!Otherwise i will ignore any post relating NON automotive matters about who knows what...

I honestly think I am dumber after reading this thread... you go right ahead and make yourself a 700hp CA since you seem to have all the answers and are unwilling to listen to the more intelligent/knowledgable members of this forum.

This thread is locked for its sheer uselessness. No one here has built a 700 hp CA. Its all speculation. Go talk to a race shop near you, make some friends there, and ask their opinions. I'm pretty sure they'll just tell you the same think we've said.

p.s. reading the factory service manual is not the way to 700hp. its the way to changing your timing belt, replacing your spark plugs, and setting your timing.
