Give me some suggestions...

I need to know some cheap modifications I can do to my KA (dohc) to make it somewhat better for drifting, My radiator sucks and Im going to replace it this week cause god knows I rev the hell outta it when I drift and I dont wanna blow my headgasket overheating it..I havent drifted for like 2 weeks cause of this But, Are there any mods I can do at home for cheap (or free ) to boost a little performance and\or make the engine a little tougher to put up with the pressures of drifting> I dont have much money at all right now cause my hours have been cut back until the second week of june..So please dont post any thing that costs alot of money to do. Thanks for any help.

Word! I couldn't agree more with Alex P. My KA is pretty much stock, aftermarket parts are expensive, intake and exhaust setups can be over five bills+, with small power gains. You might look into changing up your timing, but don't expect major gains.

Remove your Y pipe and go to a better replacement air filter. that opens the intake up pretty well few extra horse power. Advance your timming, just enough to get away with it on whatever gas your already using it. Theres a few more horse power there. You can remove your AC Compressor for free power, though im not entirely sure whats involved there. if you have alittle bit of money a 3 inch intake and 3 inch cat back exhaust really helps the KA breath alot better. You may want to look into a hi flow cat. Dont know how much power you can make there but old cats can hurt performance, so a new one will help out.

Anyways you can get some extra power threw those way. I know people say 3 inches is too big for a NA KA, but i've seen dynos. it helps them alot, one guy was putting down like 14 extra horse power with a 3 inch exhaust, from his baseline that was stock + a intake.

Also underdrive pullies can help out. but once again those things cost money.

3 inch is way to big for an na car. Prove the dyno sheets. Lets see some copies. I'll call your bluff on this one. I can go into great lengths on what your exaust actually does and how you make hp with it. Given on a stock motor you may make hp but usually you will loose overall performance.

What most people forget when they get on the dyno is that the peak hp really doesnt matter. What you should be looking for is a good torque to hp curve durring the rpms bands that you are actually using. Getting an average is more important then peak. And in drifting, you need to keep a less peaky and more flat, quick responding power band. This is why i say keep it stock. 10hp isnt going to make you drift better and a super loud exhaust is only going to draw attention.

The AC doesnt take any power if its not on.

Save your money and buy suspension. This will give you the most gains and less tickets.

here you go...

http://forums.freshalloy.com/ubbthre...b=5&o=&fpart=1

at the time of me posting this i think that site is down.. but its been around a number of times He makes power in more then just the top end, good all round power, and good top end, really picks up where the KA tends to drop off. Its pretty impressive for a NA exhaust upgrade.

Yes im aware of how an exhaust makes power. The idea being you size it just right so that the exhaust volecity stays pretty high so the speed of the exiting exhaust will create vacuum that will help pull exhaust out of the chambers. Thus helping to create more power. Perhaps my wording is off, you will have to forgive me it is pretty late.

Anyways the trick is to find a balance. To small of a pipe and the gasses will get restricted and wont be able to move out of the pipe quick enough. Too big and you will miss out on the scavenging effect i was describing earlier. However when you think about it. a 2.4 liter KA makes alot more exhaust then lets say a 1.6 liter 4AGE, due to its displacement, i know guys tend to say 2.25 or 2.5 inches for exhaust is the way to go. but i dont see how one size can be perfect (considering the balancing act of back pressure and scavaging you are looking for) for a 1.6 liter, and the same size be perfect for a 2.4 liter. add in completely different head designs intake manifolds exhaust manifolds and the whole 9 yards and its possible, just possible the old rule of thumb doesnt apply to that specific engine. (i know you know how exhaust work, im just going threw it for my self)

Of course the topic of this is thread is what can he do to be a better drifter. But he also seemed to want to know what he could do to get some more power. I was just tossing out ideas that he can consider to create extra power. Extra power however will not make him a better drifter by any means. Only seat time will do that.

I hope that URL is working because that Dyno graph is very impressive assuming its not been doctored or anything along those lines.

EDIT: Freshalloy is having some problems tonight it seems. but give it a try in the morning if nothing else... ... Ah back up now.. well whatever

Also the guy who created that thread Mav1178 has recently joined our forum, Perhaps he can comment further.

Mav is another one of the Alex's at the d day events and i know him personally. I was wrong, maybe a 3 inch exhaust would be worth it.

Im not really looking for more horsepower..Im more so looking for things i can do to the ka to make it more durable for cheap and maybe get some better throttle response. I dont wanna mod my ka alot, I plan on eventually doin an sr.

It's more weight in the car though.

less weight = better P/W ratio ~ having more hp

I agree - suspension or a differential will be good for the life of your car, whereas performance parts will be wasted if you ever do a swap.

From my experience 3" exhaust (when made with the correct length of primaries, etc) can be very healthy for the big-displacement 2.4l KA

I just saw you're in St. Pete - take your car down to Secret Services and have them help you out.

Matt is the resident drifter there and is running a KA24DE with a welded diff (last I heard from him) and totally rips it up!

He comes off as being kinda... not friendly, but is really a great guy and would be willing to help you out if they're not god-awfully busy (which they usually are).

Maintenance is the cheapest way to go. You'll add significant HP.
Keeping your car cool and lube.
triple checking on leaks, the hose and wiring. Make sure your up to the game when it comes to your engine. When you rev high all the time you'll never know what's going to snap or leak out.

Example. I keep a close eye on a rear seal (it's a slow leak) on my rotory engine. I dont want to invest the time and money to fix it, because ill replace the whole engine anyways. But I keep a close eye on it. just in case.

oh yeah! GROUNDING! geez! everybody thinks about HP, but with the proper wiring you'll be suprise on how well your call will perform! more responsive! better idle! better MPG.

As for your Y pipe, take a look at your stock intake setup, you have your air box, and tubing back to the intake manifold. Under the air box is a kind of cold air extension or something, ends up making a Y shape. Theres probably a few free horse power availible by removing it. i didnt have any problem running my like that, seemed alittle quicker and i could of sworn it seemed more willing to rev and alot meaner sounder, the sound was intoxicating actualy... I think its just there to deaden the sound stock. Anyways there are a few free horse power to be had from the engine. I would recommend stripping the interior to whatever point you can live with to get the weight down. If you are going to spend money i would sugest spending money on a LSD first. even before the sr motor.

A LSD a few extra ponies and less weight will make the car alot more fun to drive over stock, I advanced my timming about 2 degrees originally and it really improved the top end. Just watch out for predetination..

And of course follow crashdrives sugestions of matienence. Also you might want to go to a thicker weight oil if your going to be at high RPMS often. Change your oil OFTEN too man. Perhaps looking into one of those grounding kits to follow with crashdrive's sugestion of better grounding. people claim those net them a few extra horse power too. seen a few dyno graphs in magazines. nothing impressive, but if your gong to do it do it to improve grounding.. any minor power increases, take them as a bonus.

of course just general matiences. New air filter, new fuel filter and oil filter if you need it, if your cat needs to be replaced (if you have alot of miles especially) just little things man. And you can use it as practice until you get the engine you want in the car, because i promise you will want to keep that one in good condition.

I just did that y-pipe thing, It took me about 5 minutes..and from 3K up it sounds really nice. I love that sound. I can notice a little better response aswell and it does better in higher RPMS..Nice call man. Any other free mods >

Grab the timming light and go 2 degrees advanced. i was able to get away with that on 87 octane with the KA for months before i returned it to stock due to other problems.

Your local store, timming light is a device you point at your timming marks so you can see what your timming is set as when you adjust it, for further information on this topic try your local library. or google.com
