I'm just curious. I just got into imports not too long ago, and have a million questions to ask. Not meaning to be a post whore. Anyone know of any all motor KA cars?

[03-18-09-26-15]

basicallly, no.

there are always exceptions though.

How well do you think one would perform?

[Korey]

Yes I know of one who was into autocrossing for 7 years. He had to do everything in spec to stay in hius class. He made 160whp with minor mods was pretty nice though.

[aaf]

Don't they make cams and stuff for them? I'm sure you could bore it over, put bigger pistons etc in it.

[03-18-09-26-15]

You're asking an extremely vague question.

There are too many routes to answer it. You could spend 1k or 20k with opposite results.... so it really depends on what it was built for. YOu can make any engine perform how you want if you have the cash...

[Korey]

I think they make cams, but im not too sure how big they go with the KA motors and so on, but it is a vague question.

I'd like to do mostly drag. Maybe some drift sometime.

[Korey]

You don't even need to mod the motor or swap for drifting. If you do drag racing just go turbo and get it over with eheh.

[03-18-09-26-15]

Those two things have totally different needs.

Drag is gross amounts of HP, and it would cost a fortune to make an all motor KA competitive.

Drift on the other hand, is almost all suspension. I'm sure you could get 200hp NA and have a pretty sweet setup. The professional drifters have all the money they could need to make a crazy high HP car, but they usually have 350hp tops from a turbo..

Money helps lots. I'm hoping to get a good suspension setup for my car soon. What would be a pretty cheap good suspension setup guys?

[Korey]

RSR and AGX wouldn't be a bad start.

I'm ignorant, you'll have to dumb it up. You mind if I had your AIM sn to my b-list?

[Korey]

Go for it.

[aaf]

Go for it.

Alright cool. What's RSR and AGX?

[03-18-09-26-15]

RSR = springs
AGX = one type of strut KYB makes.

I was looking looking at KYB's. I had those on my Mustangs.

I guess it would help if I updated my profile for aim ahah.

Lol, new sn?

[03-18-09-26-15]

I put KYB AGX's on my mr2, personally I don't like them for the street. Looking at a Tein Electronic adjustable dampener setup. Nothing is pimp like changing the dampening while your driving haha.

Any kind of electronic suspension cost lots of $$$$

yes sir, yes it does.

Whoever said money doesn't buy happiness never modded a car.

people build up N/A 240's all the time.. pretty common... check different nissan forums... they have individual throttle body set ups and all kinds of great shit... i remember even one guy turned his turned his KA24E into a carborated ka24

Yikes, carbed isn't cool. I dislike carbed vehicles. I'll look into other n/a mods though.

[eyustfu]

it will be very difficult to get 200rwhp with a full rebuild... 160ish is acheivable if you get a different ecu, cams, i/h/e but most KA owners just end up boosting their car at about 6-8psi and you will be well over 220rwhp easily

The guy who put ITB;s on his KA24DE used the ITB's off a motor cycle, and it will not run correctly unless you have a full stand alone system which is more money.. however ITB setups usually dont give you a gain in hp but more of a better throttle response. i heard of some losing some hp

the tein flex's are nice but not worth the cash, i had that along with 2-3 other different coilovers and the edfc unit to control it was a waste of money... it doesnt no longer then 2 minutes to adjust the damper

[starbucks]

your also an idiot if you think you loose hp from better air flow and better throttle response...

the guy i'm talkin about didn't use an ITB set up from a bike...

you can make over 220hp w/ a N/A setup on a KA24DE...

ignorance must be bliss

ANyone know who makes cams for the KA then?

[eyustfu]

crower, jwt. i have the custom part numbers for the crowers..

as for the 220rwhp, do you have the dyno charts? i seen that power on the SCCA KA24E motor but havnt seen it on the KA24DE model if you can prove me the dyno charts/specifications then let me know.. i know it will require a full rebuild, high comp pistons etc but if you say its possible lets see the dyno chart.

as for the hp gain on the ITB do you have the dyno chart for that too? the only one i seen for the KA24DE is from a custom one from a gixxer. As far as i know there isnt a ITB kit for the KA24DE..

please provide charts/models and specs of the ITBs before you make your comments

[starbucks]

i don't have any sheets of anything... i have no need for them... there is a company around here that sells different stages of N/A build ups for the KA24... i'm sure they have sheets but i don't care enough to look for them...

[Megaseth]

lol, since i have been looking into this....i'll chime in...

to get somewhere around 200whp, you will need:

rebuilt motor using custom or SOHC pistons as well as balancing and blueprinting. you could do some boring, but the walls are thin, you cant bore too much over.
370cc injectors
either a custom plenum or an ITB setup like the Gixxer 1300(hayabusa)
megasquirt or some other EMS
cams like JWT, or PDMs
upgraded ingnition system
header, 2.5" or so exhaust. possibly a highflow cat.
and lots of tuning. you'll also need to remove all the parasitic devices. like get a lightened flywheel, aluminum driveshaft, lightened pully, move the stock fan and replace with a good electric setup, remove power steering and also a/c. you will also need to run 93+ octane fuel. its not hard to get over 200 hp outta the KA24DE, hell, the racing hardbody trucks were making 298hp and 280 something ft/lbs of torque. but, its not cheap, and its almost not street able.

[Kato]

Yeah...basically, for most applications, it's not worth the money. You can go boost for cheaper and end up with more power.

If I had excess amounts of money, I'd do it, though...would be fun...

[Megaseth]

yep, exactly. i'd only build up one if i just had tons of cash and a lot of spare time. i like the idea of an all motor KA, but boost would be more economical.

[eyustfu]

just curious on which ITB kit you were talking about that is in production for the KA24DE, as what i am aware of there is no company that makes them. most people have to go with a custom set up.. of course with a large amount of money you can do anyhting but i dont think that ITBs/full standalone, internal build is worth it for a little over 200rwhp..

if i had time to mess with my car again i wouldnt have turboed the KA24DE i had and probably would have dropped in the KA24E with a complete build.

from a friend's experiece with ITBs on his CTR spec B16, he said the thing is very hard to tune and there arent many good tuners to tune the ITB's. It runs good on certain weather etc, from his experiences he wouldnt have done it again if he had the chance to. not worth the time, money and performance gains involved when done with... but he loved the throttle response of the ITB's

[Megaseth]

the kit is the setup from a Gixxer 1300. they're already tuned, just gotta stick em on. not a bolt on thing, but they do line up. but yes, fuel, raised compression, ingnition, ITBs and cams will give you 200rwhp. theres a guy on NICO who is semi-close to this, but missing a few things like upgraded injectors, cams and compression. and hes making around 170 or more to the wheels.

and yes, the ITR kits are a PITA to tune. just like the old weber carb setups or the 6packs from chrysler.

yea the one guy on Nico is using the gixxer TB set up, but i thought he was talking about an aftermarket company that makes one for the KA24DE

Not as easy as you think, to stick on with little custom work etc.. you also need to change the system to stand alone... unless you plan on adding a plenum around it and running the MAF which still could give it some problems.

[Megaseth]

oh, yeah, i know how much trouble they are to make. you have to cut the stock manifold, get the couplings, etc etc. and a stand alone would probably be best since you will be needing bigger injectors.

i had though i saw somethinga bout a kit, but im not sure. i know TOMEI has one for the SR, but thats all i can think of.

yea, im aware of theones for the SR, but mainly the SR20DE.. my friend retro fitted the GTi-R ITB setuup on his SR20DET and its still giving him problems.

main reason for stand alone is because of the different air/fuel characteristics compared to the stock one...

as for kit for the KA, i'm 95% sure that there isnt a company that makes it. i could be wrong, but i looked into an all motor ITB set up before i went turbo.

Would that be cjex? If so he has abandoned it and went back to regular, too much of a pita.

Here's a link discussing making 200+ hp on a KA

yep thats him, i know he took it off because of difficulties, i drop by his house here and there every so often to see wassup.. he just wanted to get the blue car running again so he could work on his black s14
