Afterdark's 200hp KA motor

[Rockenreno]

I did a search and found very little mentioned about this motor, but I am intirgued by it and had a couple questions to ask.

From what I understand, this is a 'theoretical' 200hp motor, but I'll just assume you can make about 200 +/- 10 for the sake of arguement.

First off, are you expecting 200 hp at the crank or wheels?

Second, with the modifications you are doing, do you think it will pass smog in California? I understand you don't live here, but I do, as well as many of your future customers I am sure, but I am just looking for a guess if you don't know for sure. I know an SR20 won't pass cause its a different engine and all, but I don't know much about emission laws and whatnot. I have seen Dauntt profess his vast knowledge on the subject numerous times, so hopefully he can tell me

Thirdly, will you be just doing things to the motor, or will this include exhaust?

Lastly, have you actually built any of these before, of is it just a plan in the works?

That's all I can think of at the moment. Thanks in advance for your responses.

this is not a question for technical, as it is dirrected towards After-Dark Tuning. I'm moving this to general so Daunttless will see it.

[Nismo_Freak]

Me and Aries could build you a 200+ whp KA that wouldnt pass smog testing anywhere on earth hehehe...

Well maybe Mexico.

Here's what you can do. Go have the car tested in its current state. Then your good for a while when you get the motor in. In that span find yourself a good shady shop that will turn away cause frankly your not gonna make 200whp in a KA and pass emissions.

[Rockenreno]

lol:D

I might go for an engine upgrade like that sometime, but not for a while. I don't even own a car yet, I am used to my mom's 1990 Mazda MPV Minivan...

Right now if I do any upgrades, I'd prefer for it to be at least semi-legal...:icesangel

[Nismo_Freak]

We could make a low restriction KA that would make good power but we cant use cams. Cams are what make the KA a smog beast. We would have to use fully EPA legal parts w/ EO numbers fully visable on the parts. We cant touch the cat, we cant do headwork or cams. There is a bunch of loss potential there. Of course anything turbo wont be legal. Basically if you want to go fast "legally" your gonna have to make friends with someone that does the testing. Talk to someone that has a highly modded car and ask them were they get their "testing" done. Odds are there will be someone that can help you. If you find that we can do headwork and cams. This will make a ton more power.

[Rockenreno]

interesting, I didn't know cams made such a difference in smogging.

Is there anything you can do to upgrade power that won't have a legal effect your emissions? Why can't we just be like the rest of the world and understand that people want fast cars over earth

[Nismo_Freak]

If you want to be fast your gonna have to go around emissions testing. Plain and simple. Only things you can do legally are as follows.

Intake, Header, Exhaust, ECU (provided it does not remove any emissions controls), Pulleys.

Thats about all you can do. All the CARB EO#s have to be fully visable in the engine compartment.

Intake, Header, Exhaust, ECU (provided it does not remove any emissions controls), Pulleys.

Most likely this is what I will be doing in the near future

In a couple years when I decide I need a faster car... then I will probably get a new car unless I can't part with my 240, in which case engine swap it is!

Don't forget about a race clutch. It doesn't add HP per se, but you will regain a lot of "lost" HP due to a weak clutch. Not to mention you can launch harder, more often, that stock clutches. This will but more time off your 1/4 ET.

Daunttless's 200hp motor's include the following:

"its intake, overbore, raised compression, remapped ecu, rebuild, port and polish, headers"

He also said you can get him to add pullys, cams, preaty much whatever you want.

[Cloudedone]

I live in Humboldt Co. California, and up here you only have to smog your car when you transfer the title (like when u buy it) and NEVER again... no once a year testing like in the bay area or once every 2 years like other places... So, find yourself a relative in humboldt or any of these countys in far northern CA and register your car there... Bingo, buy the car, smog is once then do what ever you want to it, and they'll never know.

Unless of course your on a trip down south and get pulled over and the cop makes you pop your hood and they find your turbo then your kinda SOL cause they'll send ya to a smog marshal...

[SRdS14]

lol..i love these smog related threads. i always say "Move to South Carolina Babaaaay!" no emissions tests whatsoever here. whatcha want is whatcha got for life...

Only if your stock clutch is actually slipping. If it's not then no benefits will come from a clutch with more grabbing power.

Hey, : ) Alright, quick overview. As was said before, "intake, overbore, raised compression, remapped ecu, rebuild, port and polish, headers." We also include the pulleys now. So intake, overbore, raised compression, remap, rebuild, port and polish, headers and pulleys. We suggest Cams, we also don't charge any additional labor for the, just the cost of the cams. : ) We haven't finished any yet, we will have them for sale by the end of April unless someone wants one before then. : ) We will know the actual power output as soon as we do the prototyes. : ) Enjoy your day!

[Rockenreno]

about how much would it cost if someone supplied the motor from their current 240sx to accomplish the same stuff?

thanks:D

[Daunttless]

50-200 dollars less dependent upon the condition of the motor. : ( Unfortunately, we don't offer too much for KA cores, we prefer that people are generous and donate them due to our super super low prices. : )

[Rockenreno]

lol, ok.

Thanks for the info!:D

Do you remap the ecu or have someone that does it?And can I send you an ecu and have you guys remap it and how much would it be?

[burningskulls]

So what is involved in the built-for-turbo KA?
