Im not new to the world of the 240 but im seeing people laying down 500+ numbers on the dynos and im looking to build a 240 soon. As soon as i sell my truck that is. But i was just wondering what you all had done to your engines so that when i get to building mine i will be able to run around those numbers.

The 500rwhp range is pretty serious for a KA-T. Not a lot of people are pushing that much, but the list is growing.

For that kind of power youre looking at a full build-- forged rods (pauter/crower) and pistons (ross/JE/weisco/JE/supertech/etc there are a bunch) with a CR reduction to 8.5-9.0:1. Also there are a TON of little things, ARP hardware, metal headgaskets, aftermarket bearings, headwork, etc etc etc. You need a really nice fuel system to match, high capacity fuel pump (walbaro or see the recent thread I started on the subject), nice top feed injectors of at lest 720cc, fuel lines, fuel rail, etc etc. On top of all that you'll need some kind of engine managment to control it all like a burnt ECU or complete standalone (more popular at this level). The list keeps on going.

Figure for a SOLID 500 to the wheels you will probably spend close to $9 or 10k on the engine and supporting parts. Are you really looking for that range?

fiznat covered it, make sure you really want that kind of power, its a large investment and worth every penny if you enjoy working on cars.~Sam

Its what ive wanted since i first saw a 240. Im gonna dump about 13k including car price. But i have to get a car that runs since i have to sell my truck to get the cash. But thanks for the ideas. Also should i go with the IAP Stage 2 Kit or should i build piece by piece. I know IAP is a big part of this site but does anyone have that kit installed?

Post by **koukiKA240** » Thu Oct 20, 2005 6:57 am

I do, and im not a fan, nothing fit as it should and everything required modifications, i say peice one together. Other people have had better luck, as installed my IAP stuff over a year ago, so maybe they have changed since then, but i still have a bitter taste in my mouth.~Sam

No such thing as bolt on turbo.LoL

Pretty much anything actually worth putting on your car isn't bolt on.

Post by **scheffler** » Fri Oct 21, 2005 5:49 am

For those goals I would piece one togerther. I would find the parts that are going to meet the needs of your project (find a turbo that will meet your goals and then a mani and DP to match). When you buy a kit not everything in the kit will meet your needs.

I hope you are not planning on making this your daily driver.

Post by **TravBear2** » Fri Oct 21, 2005 8:48 pm

Y is that??? Im gonna get a stand alone FMU that i can program through a laptop so i can start of with a lower boost and then as i get used to it ill turn it up.

Post by **nismofly** » Sat Oct 22, 2005 7:36 pm

he says that because once you go above 300rwhp...*MAYBE* 350, it gets interesting to drive

have you ever driven and/or ridden in a car with that much, especially a light car like an S chassis?

Post by **virus77** » Sat Oct 22, 2005 10:41 pm

stand alone fmu huh? Ive heard good things about that, let me know how it goes...

Post by **fiznat** » Sun Oct 23, 2005 6:22 am

A car like this is not a good idea for a daily driver. No matter how much time or money you pour into it, you will still have mannnnyyyyy problems along the way and especially once its built and "done." The car will be out of commision countless times while you get little things fixed. Please take our word and do NOT try to make a 400+ rwhp KA-T your "get to work" car, its a big mistake.

EDIT: Also a FMU and a standalone fuel management system are two very different things. Its just termonolgy and we understand what you mean, but still...

Post by **TravBear2** » Sun Oct 23, 2005 5:30 pm

Thanks for the correction... Im trying to understand all these stuff down to the T. So you think going over 500 is to much? Well what if i just keep it dialed down until i want to kick some ***? So that im not always throughing tons of boost down its throught. The stand alone that my friend was talking about is also a boost controler and has many more capablities. So all i have to do is plug it into my lap top and i can change everything that my engine does... Should be good for an emisions check lol.

Well thanks all for the comments and if you have any ideas on what parts i should use let me know.

just turning down the boost would kind of suck because then youd have the real laggy turbo you need to hit the high power but youll have the boost so low thats its not worth it

better to start around 300 or so, thats still plenty fast enough for awhile

then if you have once you have everything ready and youre used to driving with that kind of power you can turn the boost up and swap turbos until your satisfied again

Post by **JDMEnthused** » Sun Oct 23, 2005 6:22 pm

eh.. if u havent heard have a 240 over 350hp with no stickies, its hard to control.. even with your alignment dead on, its still a little slut ( excuse the language)

Post by **TravBear2** » Sun Oct 23, 2005 9:06 pm

But if i were to go with a smaller turbo at first i would have to buy more stuff again and that would be no fun... And if its a little laggy thats no biggy.

Post by **fiznat** » Mon Oct 24, 2005 6:11 am

Its not that the power is too much, its because a totally custom engine like this is bound to have problems, whether you turn the boost down or not. A completely custom built-from-the-ground-up car is NOT a good car to rely on to get you to work, thats the point.

It sounds simple enough, you just put the parts together and everything should work well, especially with the standalone-- but thats not exactly the case. If theres one thing all of us KA-T owners can agree on its that there is ALWAYS something going on with our cars that needs fixing. I had a built 430rwhp motor with the AEM EMS standalone, and I was always having problems. Heat problems, IC couplers blowing, odd sounds that scared me, etc etc etc... things will pop up out of nowhere, no matter how careful you are.

Dont get me wrong, I love the KA-T. I would just never ever ever trust it to get me to work every day haha.

Post by **TravBear2** » Mon Oct 24, 2005 8:01 am

LOL that does make sense... Well i guess i can always use my grandmas 94 Subaru Legacy as a back up LOL

Post by **GEO** » Mon Oct 24, 2005 8:31 am

Anthony has a 450rwhp Daily Driver.. HAHA

Post by **nismofly** » Mon Oct 24, 2005 2:50 pm

does he really only turn the boost down that much?

Post by **lrb_2000** » Tue Oct 25, 2005 1:57 am

i'm aiming for the 550hp-600hp range by next summer... I was hoping to have a low, and high boost map.. one for pump gas, one for race gas.. I was going to TRY and use it for my only car.. but I got smart, and i'm going to buy a sentra or something.. my friends gets like 40mpg... i'll probably be getting.. 12. lol

do it right the first time... don't waste money. if you're really serious, just do what I did, and buy a seperate engine to build on the side.. find a car with good gas milage, but cheap.. then swap in the built engine to your 240... and build the one you pulled for backup lol.

Post by **hysteria** » Tue Oct 25, 2005 4:42 am

even when you do everything right the first time you will hit tons of snags and problems as can be demonstrated by fiznat.you have a lot of learning to do. i mean i know you want to just have a badass car thats quick and all but treat this as a learning experience and know that $13k will be exceeded if that is your target price range. you always spend more money and time on these things than you think you will, but then when it works right it's a great thing.tuning is not exactly the easiest thing to do. read read read.http://eccs.hybridka.com/http://ztechz.net/there's some information you might want to look over about a dozen times. and then look at it again.

Post by **TravBear2** » Tue Oct 25, 2005 8:22 am

I will have a back up engine. It will be stock but itll be there for what ever i need it for. Im thinking about sticking with the kits 350+ that it comes with without doing anything extra to it. Then with the extra money ill get some Tein Struts and Some BIG breaks

Thanks Everyone For the Great INfoKeep It Coming if You Have More

EDIT: Also if i just go with the IAP Stage 2 will i have to still do a low of tuning or does it come pretty well set up?

Post by **nismofly** » Tue Oct 25, 2005 11:04 am

well since it comes with the jwt, you could get an safc, since the jwt tunes are conservative many times...

you just cant change injectors and that sort of thing without sending it to jwt to get a re-tune

i really hope you werent trying to hit 350hp with stock suspension......if so, you need to some SERIOUS researching13k is a lot.. just think about it... unless you're not going to DIY..

not to flame you,but you seem to get the whole "laptop" thing from the f&f movie....?

Post by **nismofly** » Wed Oct 26, 2005 5:37 pm

tires --> suspenion and/or brakes --> power --> more suspension and/or brakes

you had it backwards

Post by **TravBear2** » Thu Oct 27, 2005 6:12 am

No its not from the F&F. My friend is going to school in Houston and him and his prof found a stand alone that can change everything that you motor does by hooking it to a laptop. No im not some F&F Freak LOL. But i do love the movie. Suspension and tire i was looking at also. wanna get a set of tein. Havent decided on drifts or comps yet. Any idea there? and was looking at least getting an 8.5 in the rear just not sure which tire yet. Its just i have a lot better idea of what im doing when it comes to the suspension and tires, the T set-up is still a little out there for me. Ive never put one on by myselfIm not taking any of this as a flame. You have all been so help ful to me and i appriciate it all.

Post by **hysteria** » Thu Oct 27, 2005 9:23 am

they are kind of laughing at you, but the comment that was made was pretty funny.it's all in good fun though.an fmu aka rising rate fuel pressure regulator has nothing to do witha stand alone. a stand alone ECU is just that. a fully programable computer that replaces your stock unit altogether. fmu's are just ad ons for low boost, and, as far as i know, there are none that have any electrical component at all. they are purely mechanical, and just increase fuel pressure to accomodate extra air entering the engine.
