my 240 and my upcoming KA specs

[240Knightrider]

Hey everyone, here is just a scratch list of possible parts i will run with the KA24DE. I would use my own engine but it has 215K miles and dont want to go through the trouble. I will hopefully be starting this project in may. I will be changing the gaskets and stuff before I run the turbo.

92KA24DE engine with about 30k to 60kAEM Cam GearsAEM cold Air IntakeGreddy Turbo kit-not sure on boost pressure yetHotShot headers-before bolting on turbo.Bosch Platinum4 sparksAEM Crank case pulleysARP Head and Main Studs Pauter Machine Billet Connecting Rod Set-might be differentRoss 8.5:1CR Forged Pistonseither Flowmaster or Pace setter, I havent decided yet. Thinking or running duel exhaust cause I hate haveing a 3 inch exhaust pipe.redoing drivetrain with something not sure yet

still more but these are main ones, like I said Im still a newbie and any help is appreciated.

Bosch Platinum4 sparks? I've heard these dont do well with KAT's

Since when does AEM make cam gears for the KA?

Cold air intake? hmmmm huh?

Headers? You got a V8 in there?

[240Knightrider]

well, I kinda have mixed the two together, then engine before adding turbo kit and engine after. 1 header from hotshot for ka24de. What would be the best intake with the turbo.

[240Knightrider]

maybe i was wrong about the cam gears, maybe Ill try to get them custom made.

[SloS13]

dont waste your money getting a header. May is only 45 days away. The turbo kit will come with an 'intake'

[nikn]

if u are going for a turbo, you dunt really have to worry bout the cams n timing. With turbos, overlap is bad, so the stock camshafts and cam timing will do fine. Only if ur going to be goin for something over say.. 320hp, then you might begin to consider cam tuning, still it is not really necassary. Thats just my opinion... Itll help even if you are running 6psi, just that personally i dun think its worth it.

[node]

nikn - wouldent he still get get some high RPM benifits from longer duration cams if he adjusts the timeing between the cams so there is less overlap?

[240Knightrider]

hey guys thanks for the post, like i said im still a newbie, what exactly is the overlap? Im going to be getting better cams too, so I figured I would go ahead and get the cam gears also.

[SloS13]

Ive heard of people replacing their intake cam with an exhaust cam. You'll have to get it re-keyed or whatever you want to call it.

[240Knightrider]

im not gonna try to convert something, i just gonna go by the book, and maybe bend some rules here and there

[240Knightrider]

well, does it make better performance wise, or mess everything up

[SloS13]

It messes everything up :rolleyes Thats why people go through the trouble to find one, re-key it, and install it.

Spending more money doesnt always mean getting more performance. If you really want cams and can get an s13 exhaust cam for cheap, why not just do that?

[240Knightrider]

I am still a little confused about the first part. If it messes everything up why go through the trouble of re-Keying it and intalling it, why not go with a normal part.

I know spending more money doesnt always mean a better part, or buying name brand. I buy the best and what I know works, my decision is not always finalized by the price of the product.

[y3llows14]

Damn yo...is that an RB26DETT in there. That look mad tyte. Im thinking of doing the same to mine too. I thnk I might get that intake first though.

240Knightrider,

It sounds like you kinda have a lot to learn about turbocharging - no offence.

You should do a LOT more reading before you even think about spending your first dollar. Read Corky Bell's book, look at http://www.howstuffworks.com 's article on turbocharging (and combustion engines as well), read this forum top to bottom and whatever else you can possibly find.

Listing what parts you want to buy is never the way to start getting into this, it'll get you flamed to no end and it slows down your actual progress to your goal. Go for it man, but learn about it first. Good luck!

[240Knightrider]

no offense takin, but I know how turbo chargers work, and Like I said before, I was wrong with the AEM parts. But most of what is listed is the parts Im going to run ""BEFORE"" the turbo bolt on. Of course you dont have the cold air intake and Headers on there when you run a turbo, I know the plat4 wont give enough spark with the boost of air. Any idiot that knows how a turbin spins on a turbo knows that. I realize I am still knew and have a lot to learn, but Im not stupid and I asked for what everyones thoughts were, and thats precisly what I got, whether it be bad or good. Me listing what parts i am thinking about buying gives me the ability to find out what works and what will not work with others experiences in the past.

[240_2NR]

FIZNAT wasnt saying u didnt know how a turbo works, but the actual work needed for it to work (if that makes any sense) and what would happen if u put a certain part in, like the cam thing comes to mind, the fact that u didnt know what overlap is and does is what he means and there is a lot more than that, although u seam to be aware of it take fiznats advice and read up on it, i hate to say it but do a search, look into the past posts there's tons of info. just so u know Overlap is the length time the intake and exhaust valves are opened at the same time

240Knightrider: take it from some people who have been where you are. If you are planning to turbo soon, do not spend money on anything that you will not use with the turbo. You'll waste more money and take longer to get the turbo.

Just a couple of more specific things. I'd probably stay away from the Bosch Platinum +4's. Not only did they sick on my old 240sx, but when you turbocharge, you will need to close the spark plug gap some. These are much different in the way they are gapped and I currently know of no way to regap them with any ease.

Decide what boost level you want to reach before deciding whether or not to rebuild the bottom end. You can boost a pretty moderate amount on the stock bottom end so long as fuel delivery is tuned well. The main(bottom end?) and head studs do not really need replacement just to turbocharge. I'd decide on what boost level you will run before even thinking about this.

Dual exhausts on a S13 would be difficult. The gas tank is in the way on the right side. And flowmaster isn't a great muffler at all. It's better than stock, but a good perferated core, straight through design will provide better flow and amazingly enough, it will likely be quieter.

I'm not sure what you mean by redoing the drivetrain. Clutch?

Lastly, the Greddy kit will probably need some modification to work on a S13 KA. The downpipe will be too short and if you go with an intercooled set-up, you will likely need to modify or have new piping made. Also keep in mind that you will also need to reset the E-manage to clear the preprogrammed tuning as it was designed for the S14. The S13 KA is not a supported car for the E-Manage currently, but it can be made to work. But the tuning will have to be done from scratch.

Here's my opinion on Bosh+4's. Electricity always goes to the shortest ground right...so having four ground tips doesn't achieve much. Denso Iridium, or any Iridium for that matter will be a much better plug.

[240Knightrider]

Thanks for the tip. I will go with those plugs, or similair. I just want to say thanks to everyone that has helped me out. I know i dont know much in the area of completely redoing the engine, but that is why im on here. I also have a few friends that have a clue that will come by and help out. I will either have a cam set up or just take daily pictures on my site to keep you guys updated. Not sure if anyone really wants to keep updated, and im sure I will have questions as I go along.

I've been using Bosch + 4 platinums when it was naturally aspirated, and am still using the same plugs now under 9 psi of boost. Have never had a problem with them yet....

Are the iridiums really worth it?!? They sound kind of like snake-oil to me.

What are all the other people sub 10 psi using for spark plugs? I was thinking of going to iridium a while back, it can't hurt for a cheap upgrade.

[WDRacing]

Snake oil is the bomb dude....wanna buy a case?

[MarkEmark]

lol, make it five!
