yes, anything is possible but you better be willing to spend 10K+

what is the s15 actually, is it a whole new car or a styled up s14 basically?

The S15 Silvia is a whole different car. The S14 SR20DET has 220 HP at 6k RPM and the S15 SR20DET has 247 HP at 6k RPM. The S15 has a different exterior as well, see pics below for S15 pics. The S15 also came with a 6 speed tranny although racers and drifters in japan swap out the factory S15 transmission and put
in the S14 SR tranny. The gears are a shorter width in the 6spd so that they fit inside the housing. Because the gears are shorter, they are weaker and the drifters/racers end up breaking them. The 6spd tranny can be used on the S13 and S14 motors with no modifications except tha you will need the S15 driveshaft as well.

I know all of that, was just wondering if it is actually a s14 with some restyled parts, for example a 98 and 99 mustang are pretty much the same car but the 99 year has been restyled. I really don't like the back of the S.15, think it will look completly awe-insipiring with that front end on the hatchback. I have never seen one with my eyes and only a few in pictures on websites.

Now I am really unsure of this, but JUN Auto Mechanic, being that they have close ties with Nissan, can obtain bare-bone Nissans from the Japanese factory. I don't know if they can provide customers with this type of product, but they use them for their own testing beds. Their famous Hyper-Lemon Silvia came unpainted, unupholstered, riding on steel wheels, to be fitted to their needs in their own shop. Who knows, give them a call but other than that, to my knowledge, I have no other clue.

Although the S15 has a significanlty advanced chassis, it is basically founded on the same schematics, with better reinforcements and balance than the S14. To put it another way, the sheetmetal may be all new, but underneath, the chassis and powerplant hardware is related--but better.

OK, if i had all of the rear body parts from an S15(including taillights) could i just bolt it all on in place of the 240sx's rear end? Or would the trunk's shape fuck it all up? Im asking this B/c late model 240sx's are on the same chassis as the s14 and s15

The first pic is the rear of an S15 Silvia, the second pic is a pic of the rear of an S14 240SX and the last one is a pic of the rear of an S13 240 SX. As you can see the S15 rear will not work on either the S13 or the S14

I thought they were two completely different cars, just as the S13 and S14 were. Its a remade Chassis, Tranny, Body, and engine if I am correct.

But like you said earlier in this thread, it can be done for loads of money. It would be about as difficult as attaching an A-pillar forward front clip onto a car at the body shop, after getting wrecked. Body shops do it all the time, whether it be for front or rear clips, and it's much easier than trying to mold on each individual part (raw fenders, trunk, taillamps, windows, etc. They just remove any mechanical parts, chop the car in half, and carefully align and weld on a new clip.

The only difference between the average job and this one is that from the B-pillar doorline forward, the S15 sheetmetal might vary, unless you get the proper door paneling as well. There is a nice crease in the S15 that runs from the upper corner of the taillamps to just above the front fenders. But the innermost skeletal structure is pretty much the same between the 14 and the 15. Most decent bodyshops should be able to creatively compensate for the very slight differences during welding.

Of course, the biggest downside for this extensively detailed job would be cost. An entire S15 rear clip will amount to quite a pretty penny, as will the labor. And then you've got the problem of aft safety. I don't know what Japanese rear collision standards are, but this could be a concern for some.

If you will see the photo below, notice how right from the back of the doorline (B-pillar) to the front of the doorline (A-pillar), the general shape of the car is the same between the S14 and S15. Nissan didn't make an all new car from scratch. They simply changed what they could, and what they could includes the rear fascia to C-pillars, front fascia to A-pillars, and interior.

In this shot below, you will see just how different the two cars can be, but be advised, it's pretty much all cosmetic. Automakers have the CAD computers which draft out the shape of their future cars, but for economic reasons they generally tend to preserve parts they've already got--everything from engines, to hazard-light buttons, to chassi--and Nissan has done just that in this case.

Think 1997 and current Nissan Maximas: from one perspective, the two can be considered completely different cars, with the newest models bearing new front and rear facades, newer body paneling, a revised interior, and a bigger more powerful engine. But when you look at it from a mechanical perspective, they are really not. They have the same general dimensions. The engines are from the same family with the same general technological features, but with some power adding improvements (in the case of the Maxima, sheer displacement increase from 3.0 to 3.5 liters for the VQ30DE to VQ35DE, respectively). By the way, I'm not saying "facelift" because the changes in these scenarios ARE greater than those of minor faceliftings.

This is why I don't consider the change from S14 to S15 to be as drastic as from S13 to S14. The S14 and S15 both share the same steel chassis, but the S15's is firmed and balanced for more predictable handling. The wheelbase is the same 252.5 cm for both models, but they have different overall lengths due to new skin. And believe it or not they share essentially the same SR20DET, but with with a few tweaks to put out closer to 250 hp. You're right about the transmission though, it is an all new 6-speeder, but that's not a huge revelation.

The biggest difference is the skin and the interior--and a good automaker knows that if they can wildly freshen up the appearance of a car, but not mess too much with a working and selling chassis/powertrain formula, then they can save money on their next model. Of course, this doesn't always work and sometimes the companies need to redo the entire car from the ground up, and Toyota's newest Celica is the perfect recent example for this situation.

Don't get me wrong, I'm not saying that the S15 isn't that much better than the S14. In this specific case, the performance of the S15 seems to be the sum of its improvements. Those who have reviewed it said the S15 felt more like the nimble and tossable S13--qualities which the S14 lost with growth. And damn, the car IS beautiful, inside and out.

Yeah, almost anything that you want done to your car can be done, but just as long as you have the money to back it up. I saw on www.unstable-hybrids.com that they are going to try and install an RB26DETT into an S13 240 SX. The motor alone from them costs about 8-10k and they say that labor will be AT LEAST 10k. So your looking at least at 18k for this swap. If I had loads of money then this would be cool to have because you would be one of the only guys if not the only guy in the country to have this done. Personally I think if I waited a long time and saved up 18k then I wouldn't want to spend it all at once on a motor swap. I'd like to spread it out over a lot of things. So yeah anything can be done but just as long as you can afford it :D
