yeah i have a ka24de wondering if anybody knows pros and cons of turbocharging instead of just buying a redtop sr20det

Larger displacement, cheaper since you already have KA in your car

sr20=reliable.. ka24det=ka-boom. dont get me wrong i have a ka-t myself and I love it. but yer gonna need a new clutch most likely and alot of other odds and end parts/ which will in the end be just as much work as an sr20 but its cheaper to go ka-t and more power..before considering even turbo'ing the ka yer gonna need compression test . make sure your ka runs great even before the turbo because adding boost will most likely make iany existing problems worse.

LOL if you think this is something new...

But anyways, yes you will get more displacement and a longer stroke, which equals more low-end torque and a relatively faster spool than the sr20det, although your redline will generally be lower. The KA24DE's stock internals can hold about 300rwhp before they start to get iffy, although if you are EXTREMELY good at tuning then you can get them up to 5-600hp for a little while. Anything past 300-350 and your piston rings are prone to shattering under knock if your tune isnt good. The stock rods also top out around there, although I can't remember exactly what the threshold is. If you have a decent KA24DE already in your car, turboing it has a higher $/hp ratio than swapping in an SR20DET, but it all really depends on a bunch of variables, such as shop work (if you would need it...), parts prices, acts of nature, etc.

A KA24DET suits my needs perfectly, thats why im going to go that route. A fun ~250hp street car for a relatively low price...

Yes, turbo charging any car will put more wear and tear on the engine. But a conservative setup with good maintenance wont be too bad.

They were fast on shipping, ordered on a sunday and they had it shipped the next day. Their site was recommended by another nico member somewhere in the forums, so i figured i'd give them a shot.

Oh god... another Arlington kid with a 240...

Weather's getting warmer now... don't get into any trouble at the Mayfield and 360 meet, ok?

But if you wanna do KA-T, you need to find Stephen, Brad and Eddy... They're the local 240/KA know it alls... lol

Its mainly what your applications is going to be for. For simply a little more power at a reasonable price. Yeah, I think the KA-T would be alright.I plan on re-doing the internals and such in my build anyway so am going with SR. I am also in no hurry or have the greatest cashflow so it will be a slow process anyway.

I have been through 3 ka's and seen my friends for years still boosting on the same sr's. I'm a ka dude all the way dont get me wrong I've done plenty of sr swaps and ka swaps .I have a 300 hp ka-t right now on stock internals and I KNOW it probably won't make it a year just because its making so much power on stock rods and pistons, and its running great as it is right now too. I love saying ka-boom aswell hahah. if you want cheap power ka-t. if you have a daily driver I suggest a sr20. or a mild ka-t setup

That's from previous owners not changing the oil or the engine burning oil and the owners not knowing.

My sohc has the worst treatment possible. It sat for 6 years in an impound lot and then I got it and I've put 42k miles of drifting and daily driving with a severely rattling timing chain.

If I had a KA that had regular oil changes, I wouldn't hesitate to run 300WHP reliably every day.

Problem is so many people half arse the tune so they blow easy. So they get a bad rep.

One HUGE thing I love about KAs, you can go to advance auto and buy a fel pro head gasket that can hold 500whp. And every other engine part there or at a dealer with almost no hassle. Can't do that with a SR/RB/CA with out being told to wait to cross refrencing a bunch of crap.

Well, a Pro would be that you could drive the car with the KA until you get the SR and get lots of hugs and kisses from the JDM klan. j/k As for that, for me that's it. I just don't know why anyone who wants more power would want to swap a larger liter/longer stroke engine for a smaller one and then build it. That's like telling a 396 Chevy owner to swap it out for the 350 (yeah, I got a Nova too). So the real questions are what are you looking for (re: power) and what do you want to do with it (drift, drag, street, beat the crap out of modified Corvettes, beat up on some stock Camrys, etc ...). Personally I would set your goal for HP/TQ numbers and then start asking questions from there.

im gonna tell ya you have to do:1.buy 2 full sets of gaskets from the oil pan up 2.buy new oil sump/filter, water pump ,belts,hoses and spark plugs wires,dist,cap,rotor,fuel filter/pump fuel pressure regulator,injectors 3.then add boost

p.s. the tuning might be the hardest part of going ka-t so heads up

turbo ka's get a bad rap because people just slap a turbo on and dont spend money where its needed. they are a perfectly reliable motor if you take your time, build it right, and dont cut corners.

i know because i just made 394whp with mine two days ago.

so to the op, search alot and see if its something you wanna do because correctly setting up a ka for boost i think is a tad more involved then just changing out to an sr. but when done correctly you can make more power on less boost with a ka.

IMO a full rebuild is necessary before turboing a 17 year old engine, just to make you not feel sketchy all the time. Probably not needed for good KAs that were well kept, but making your engine stronger doesn't hurt.

KA's have cast iron blocks, so they're fairly strong. Just like everyone else said, make sure it runs strong and/or rebuild it with your turbo application in mind. It's not cool or fast if it's on the side of the road.

So point of the conversation is take care of my KA and my KA will take care of me so mild turbo setup with regular maintenance should be for me i dont want a track car but if i get turbo i want my car to be a noticeable 240 out there i dont wanna be just some other kid with a S-chassis
