ok... look here. Im trying to buy me a 240sx for really cheap for a project car. Ive been looking at the 1995 240 and i can get one for really cheap. But the point is that i have been reading about the sr20det and i wanna drop it in the new car. im new when it comes to 240s and i need to know how hard it is to drop a s15 in a 95-98. Is the 2001 240sx's either mounting brackets different or the wireing harness or transmission different from a 95. Simply I need to know how much harder it would be to drop an s15 in a 95 than in a 00

oy. Well, we get this a lot, but lets get your terminology straight.

s# = chassis code for the silvia line (and the early Z line), nothing to do with the engine directly.

The 240SX was never known as such in japan, as the 240 part denotes the engine size in deciliters. The car that looked the same as the hatchback 240sx was called the 180SX and then later the 200SX when it recieved the SR20DET. Everything else that has an SR20DET in one form or another was known as a "Silvia" in japan (except for the sil-80, but that was only for one year).

As for your question, putting an SR20DET into a 240SX isn't terribly difficult, because the engine was made to be put in the car anyway. The difficulty is obviously higher if you're putting the later model engines in, as they weren't setup for the chassis specifically. The s15 SR20DET also had a VVT system, which would complicate the swap more.

Honestly, the best and cheapest solution is to rebuild and turbo the KA.

the s14 also had the cvtc, only the s13 models didn't have this. if you're planning to build the motor, the s15 motor will not be neccesary since the s14 sr20 have the same potential for a lesser price for the engine. the s14 sr20 will do just fine. the only hard part if you do plan on putting in a s15 motor will be the transmission fitment. i haven't done research on this, but i believe the six-speed trans is more longer in length than the previous models. feel free to correct if i'm wrong about this.

in america, all we have under the 240sx name:

89-94 s1395-98 s14

unless if someone want to drop the sr20det in a newer model frontier

not to question your judgement, but i have been looking around for some stuff for both engines and the sr20 just seems like a better pick seeing as you will start off with around 245hp if everythings tuned right and 155 with a ka as well as the sr20 already being turbo ready and the ka being naturally aspirated so the ka' s turbo will be a b**ch enough as is just to get the engine ready to turbo. So I guess what i was really asking is would it be too much trouble to drop a sr20 from a s15 silvia into a 95 or just save up a little more money to buy a 00 240 that is the same year that the engine was designed to go into in the first place. just whats different in th 95 240 and the 00 240 simply put. unless they don't even make 00 240s in the us. Please feel free to correct me if im wrong about anything (which i probably am ). OR!!! if i just got the s14 what would you advise me to fix on it to make it as good or better than the s15 because from what ive seen is the s15 only has an improved T28 turbo, higher boost lvs, and 444cc injectors over the s14 so would that be a good direction to go???

Some one just ecplained the modle years of the 240's in this same thread, they stopped in 98, people have done the math many and agrued the pount may times, turbo ka can be about the same price as a sr( sr costing a few thousand plus install KA needing a rebuild and used turbo parts)spend some time reading the SR forums and the KAT forums alot of questions have already be answered...

Ok, you could pick up a s13 red top for cheaper than turboing a ka, but hell, for the price of a black top from an s15 and transmission, harness, etc. you could buy the greddy kit with the f/m upgrade and a decent exhaust...and have a faster all around car due to the more flexible powerband. if yo want high rpm entertainment then the ka isn't what you want but if you ant a great daily driver/ real world car, the KA is a good choice...but you'll never get everyone to agree on which is best...it's like Tyra banks and Natalie Portman...both great and hot...just different, have fun

245? The s15 SR20DET has 250, but it does it with 10:1 CR, meaning you're not going to be able to just crank up the boost. The other SR's have 205 bhp, KA's make around 220-230 whp by just bolting on a turbo.

In fact, I'd say it's less of a ***** by far.

They stopped production in 1998 in the US, we never got the s15.

Actually you can buy the s15 in the US, you can't drive it in the street of course but on the track its no problem, there is a dude in torrance who is selling three s15's currently. I know because A) I've seen them myself, and B) I've seen them myself. Also you can go on autotrader.com and look for a model year 1999 240sx and the listings for the car will come up.

I like it here...I'm kinda sick of all the driving (I work in La Jolla). Tecate's in a good place, close enough to sd and tj but far enough away to be a much more low key atmosphere. Plus, the mortgage on both of my houses is less than a 2 bed apt in sd. Where do you live chingon?

el paso tx... moved from Juarez, chih, mexico a couple of years ago. Town is big and calm, but at the same time boring. Nothing like crossing over the border for some midnight fun.

There's no reason why it would be listed as a 240sx. The s15 never recieved that nameplate, as it never came with a 2.4L engine.

i dont mean to barge in here or to question what you said, but i did find out that there was 240SX's Marketed in japan, as 240SX's.. They are the SAME as our S13 Hatchbacks but they are Right hand drive and have the SR20DET allready in them.

this came as a surprise to me, But after watching some drift video's here where done in japan the one guy said that he's went through four 240's and he is on his fifth.
