ok so a buddy of mine is really good wiht cars... takes apart his civic for fun. and he just like everyone else here says i should go with the boost. well i think im gonna take everyones advice. mostly because he says he can get it for me around $1500 for turbo fmic and all that good stuff. well no turbo timer because "theyre for lazy people that wont sit in their car for 5 min" haha but yeah ill eventually get one to make it last longer. so i just wanted to know a few good turbos too look into thatll give me a good bit of power. and what kind of increases can i expect

Well the easiest thing you can do is go with the S13 red top(older and cheaper) or the S13 blacktop(most likely newer and a little more expensive). Check out these sites. They all have a pretty good rep.

Also check the links to the left of the screen.

are there any perfomance differences in the red and black top? if not i think id go with a red top because it seems cheaper and would look better with my red paint. does the engine use a fmic?

No there really arent any differences between the two. They both have have a factory rated 205hp with a T25 turbo and a side mount intercooler. Most of them dont come with the intercooler,ic piping, and down pipe. You are better off with a fmic anyway and a downpipe could be bought for pretty cheap.

I plan on geting an S14 within the year and plan on doing an S14 SR20 swap. The S14 is only 15 horsepower more but has a better T28 turbo and variable valve timing. Since Im only 17, doing this is gonna be rough on the pockets b/c the S14 Sr is about 1000-2000 more expensive than the S13 red top.Oh and btw, a boost controller could give you some better than stock #s.Be careful not to push it past the 12-14(14 is really pushing it but still safe depending on the engine/turbo condition) or else you could run into major problems. A Greddy Profec B is pretty good and not too expensive. A turbo timer would also be a good investment. You'll also need boost,air fuel ratio ect... gauges. You might also need the gauge cluster from an S13 but I heard there are ways to get around it.

i read somethin sayin if i keep the ka24de engine dont go over 12psi on a stock engine. so id probably stick with 10psi jsut to be safe. maybe hit it up to 12 once or twice. but i want to keep the fmic hidden if i get that so would grill inserts (aka chicken wire) cause a problem? i dont want people to be able to look at it and say oh hes got a turbo its fast. have you looked at ebay? i saw a few red tops on there i may go for. it seems to be the cheapest way to do it. problem is the engine could be bad.

Hmm I dont know obout the grille inserts. Ill have to get back to you on that one. Dont buy engines off of ebay unless you research the company that is selling it and are satisfied. Many problems may occur like getting an engine with a cut wire harness and or a missing ecu. Other problems be with the engine and or turbo. Also make sure you get as much history on the engine as possible and try to deal with companies that actually go over to Japan to and pull/ inspect the engines themselves. I know ebay is the cheapest way to go,but try to steer away from it. Also your best bet would be to buy a front clip. That way you would have most if not all of the necessary hoses you would need. The side mount ic is included depending on where you get it from. This may be of help if you cant afford the front mount when you get th engine. Are you and your friend gonna install the engine yourself if you get it?

front clips are expensive so i think what i may do is just go ahead and turbo the ka24de and then maybe in a couple years ill either buy a sr20det or a different car.

Well how much are you willing to spend b/c I know some good sites that offer pretty good prices on front clips.

well $1500 is what id like to stay under or around. for a front clip i could go up to $2000. its not relaly spending the money its more the whole hp for the dollar thing. if i can get 205 hp for $1500 on a ka24de by turboing it or spend $2000 on a sr20det and get 205 hp then ill go for the ka24det instead. unless that sr20det has under 50k miles and its got everything i need then i may go for that. it all depends on what i find and how much money i get

Heavy throttle has some high quality low mileage clips for 2900 its alittle more than what you are willing to pay,but in the end its worth it Well the positive thing with the sr is that it is built to accept larger turbos without major modifications. Ill try to find some more price qoutes soon.

to me it seems better ot just get the motor with the wiring harness ecu etc and then just buying a fmic. i read somewhere on this forum that diesel trucks have big ones and you can get one off a truck at the junkyard... and i live in NC a LOT of people have trucks out here. just a thought of somethin could do... what kind of power would a ka24det put out?

Not sure bout the ka24 but there are many guys on this forum that have done it and say that its pretty fast. If you get just the engine just try to get as many original parts as you can for the amount you are paying. and yae getting a fmic from the junkyard aint a bad idea.

A KA24DET can put out quite abit of power. Some people claim it is better than the SR because it has an iron block (no "sleeving")--but this is only relevent if you push the limits. See http://www.unstable-hybrids.com.

Ohh, and 2 words:RB20DETRB25DET

trpower7 I was just giving info that I was told from a shop and other web sites. I respect your opinion for the fact that you are a long standing member here. Can you please tell me what info is wrong ar partially correct. I dont want to tell any1 else incorrect info. thanks for your reply. Im looking forward to your response. Thank you.

pstickne, I myself might go with the turbo ka b/c I may not be able to afford the engine and problems that may occur. I still want an sr though.

Danm3286, sorry for any mis information I have given you.

jdm, have to consider that with an engine swap (RB20DET clips can run for as low as 1200) you get a propper ECU, injectors, fuelpump, turbo headunit, piping, intercooler, etc... and a relatively "new" engine/transmission to boot.

Any path you take, know what you're getting into and keep some reserve for those "fun things" you'll run into :-)

if you said anything wrong its no problem at all. the info i get from here i take as knowledge from someone i dont know. so i dont look at what one person says and say ok thats gotta be right because i dont know who you are or what you would know. if 10 people said the same thing id take it as probably true. and anything wrong you said is ok i appreciate you trying to help out.

1) There are big differences between redtop and blacktop SR20DET engines:A) Redtop is high-port, black top is low-port (heads)B) Blacktop has some incarnation of a variable valve timing systemC) Blacktop makes about 15 more HP out of the box2) Most engines sold by any reputable importer come as a COMPLETE SWAP, which means SMIC and stock piping. Even non-front clips come with these items. A down-pipe would have to be fabbed. 3) The SR is NOT engineered to take bigger than a stock turbo in its stock form. This is simple logic. No auto company ever engineered a car so that you could change a major factory component (like a turbocharger) with ease and safety. You may be able to do this easily, and have it work well, but to say it was "meant" to have this done is completely false.

Next, information like what power a KA24DET can put out, what is required, and how much it costs, is CLEARLY available in the………turbo KA forum!! Information about all the specifics of an SR20DET, the swap, the prices, the dealers is available in………..the SR20DET forum!! I’m suggesting he learn to use his sourcing skills to find vast amounts of information from the experts that have been doing this awhile and have posted concise, correct answers. It’s not that your answers were necessarily incorrect, but they are rather vague, and you seem to be learning as you go along just as he is. Having him rely on your information is somewhat faulty. It’s why we have stickies and all the different forum areas.

Also, anyone who is listening to a friend like our questioner says he was speaking to in his original post needs a COLD dose of reality. This is how cars get blown up or taken apart with reckless abandon and totally screwed. The key is to do active research into all aspects instead of posting and saying “Everyone tell me answers now please!!!” Too many people are woefully ignorant and unable to use accurate sourcing and information finding skills.

Well I know the difference between the S13 red top and the S14 black top. The black top I was referring him to is from the 180 sx. The one I want to get is the S14 wich has the variable valve timing 220 hp, and the notch on the back of the valve cover(I think thats what its called). I also know the the sr isnt "meant" to accept bigger turbos when it was engineered. You would need to modify the engine a bit (fuel injectors ect...) for it to work properly and it does come with ease as you have said. I should have used a different word than "meant", a mistake on my behalf. I also sould have recommened danm3286 to the sr20det and ka-t forums after giving him my $.02 wich is compared to the $1.00 the experts have to offer. Thanks trpower7. I appreciate the corrections on the somewhat vague info I have given.
