i like the 240sx and know it has potential; i'm thinking about buying one and making it fast this is where the problem is. it seems as though this car would be a ***** to make it move the sr20 is illegal bringing a whole nother group of problems despite the install. and going the ka route means you need to rebuild the bottom end to put on a 3-4k turbo kit which will only net you 220-250 rwhp anyway. someone please explain the simple way to do this since so many of you already have, and dont just say use the search button cause all that brings up is a list of people telling others to use the search button. btw if i buy a 240 w/ an sr20det installed it's still illegal right? hows that work with getting it registered in CT granted it's not from around here

I wouldn't know about that illegal hassle deal. Just be like me and live where no one cares! However, i think you are wrong saying that it takes alot of money to get the 240 to move. 240's haul *** with relatively little money, whether it be an engine swap or with upgrading the KA. Personally i prefer the swap option but many like the KA-T and I know for a fact you can get more than 250 hp out of the KA. I have heard of 400+

240 rwhp at about 7psi. thats on the stock boost with the kit. the whole point ot a a turbo is that u can turn up the boost. with a fully built engine you can easliy turn up the boost to say about 15psi and get over 350 rwhp out of a built ka.

thats on a fully built engine.. i'm no mechanic when it comes to stuff like that and dont have the downtime to be w/o a car so tearing into an engines internals is a little bit of a far step for me. are the sr20 and rebuilding the ka the only 2 go fast options? anyone know about emissions in ct? can the sr20 get by?

There are guys doing 300+, Even 350 HP on stock bottom end KA's. Dennis is one of them and he's been posting lately. I run 6.5 psi on my stock bottom end. AS soon as I get a boost controller and dyno time, I'll try to pull that up some more. Maybe 9-10 psi until I can get bigger or supplementary injectors. Then I might start reaching to the 15+ psi Arena.

Ummmm... ask Aries and Nismo_Freak about that!!! You can get some engine mounts from them and follow their lead. Aries' 240 sports a "little" 'ol LT1!!! I'd say that's a pretty nice alternative to the KA-T or SR.

ARIES'S swap still amazes me, how the hell did he fit it in there, and wire it correctly, and its so damn fast, geez im envious, anyway, im not too sure id turbo a KA with more than about 90k on the clock, its just too risky to use boost at that old of an engine without a thorough rebiuld, hell for that matter, go to the scrap yard and get a KA out of a newer 240 and turbo up that bltch, a used KA motor out of a 97ish 240 wouldnt cost u but less than 800bux dude, and that way u could build hte motor u bought and run the stock one until its done,sure it would take time, but do it right the first time and dont get urself in a rush, good luck

That's what I'm in the process of doing at the moment. I went to the junkyard, found a KA from a totaled 98 with less than 30k miles on it. The car had been rear-ended and totaled. The engine is in pristine condition. All for 600 bucks! :D

Now I've got a relatively clean slate to start building from.

options are limitless int he motor world...Technically, an SR swap is not illegal. As long as you use a motor from the same year as your car or newer, and install all of the original emissions equipment that came on that year car originally. For example, an EGR system on the downpipe of an SR20DET...

Truthfully, anything is possible...We put a catalytic convertor on my car and passed Houston emissions and dyno testing with flying colours.

so if i hook up the sr20det on a 240 it's going to be fine as long as i keep on the cat and all that? that doesn't seem too bad. also do you have any negative opinions about me buying a 240 that has an sr20det already installed? and would that have an possible benefits, or negatives in getting it registered?

That all depends on your local emissions laws. Where i grew up (Cali), you would fail no matter what because you will fail the visual inspection (the smog people are not dumb, they know the car didnt come with a turbo). But it is not impossible to have a clean running SR20 pass the actual emissions (sniffer) test. So i would start off by checking into exactly what's invloved with your local emmissions test.

thats the shady area i was trying to stay away from, i dont want to deal with the legal complications that come with the sr20. is the 240 the only good performing rwd car for cheap? i was looking into a mustang5.0 but i dont like american cars, and the next car on the list was a eclipse gsx though i'd rather have rwd than awd.. anyone have any cheap recomendations? or experience w/ the sr20 in connecticut

No, the 240 is not the only good performing rwd. The miata and rx-7 both have a ton of potential, although people would probably laugh at you if you drove a miata. mk3 supras are cheap, and 1st gen bmw m3's can sometimes be found relativly cheap. Old z-cars are really cool, but you have the problems of an old car. And the 280zx and older 300zx's are ugly. There are definatly other options, its just with the 240 i think you get the most bang for the buck, and will probably be the most reliable.

the miata is a girl car.. i might as well drive a scooter. the rx7 is real nice but the leter models which are the good looking ones get expensive as hell while the earlier ones are just ugly... are there body kits that make those look good? and the rotary is unreliable.. the 240 looks like the only way to go
