SR20 Swaps into b12 and B13 sentras

[outcastcat]

Hey is it possible to swap the B13 SE-R stuff into the older B12. They are a lot easier to come by, for cheaper, than SE-Rs. How much would the drivetrain cost (bout 700 dollars for transmission and engine is what ive heard).

Does anyone know what is the engine is in the B12s? is it the GA16 like the regular B13s?

Whats a good replacement for the transmission in the B13 SE-R (notoriously bad later in life)?

And finally, why is there a RWD SR forum in the Sentra area. If it was offered in RWD id REALLY like to know.

Transverse means sideways (FWD), longitudinal is front to back (RWD). As for your other questions, I'll let one of the other guys handle those.

I knw what it means. I want to know if the Sentra/200SX was offered in RWD. As far as I know it wasnt.

[outcastcat]

Whats it take to swap the SE-Rs Sr20DE into the B13? Is the transmission different from the GA16 manual, other than it is a LSD? Can it be shoved into a B12? But most importantly how much work is the SR20 swap into the B13 chassis, fairly bolt up or lots of work?

[outcastcat]

anyone got any info on this?

And whats the engine in the B12, i assume its the GA

The older 200sx was RWD. CA equipped.

As far as swapping a DET into a B12, have fun, let me know how it goes. To make an SR20DE powered B12 we need everything off a Sentra SE-R from the steering wheel forward. This includes the motor, trani, ECU, wiring harness, mounts, suspension, brakes, axles, and radiator. To find all of these parts laying around a junk yard in good condition with a decent price tag would be close to impossible. So basically you would have to find a donor car somewhere. Other than being unique, I don't think you would see anymore benefits from just having a SE-R.

[RED_DET]

First off you can make any B13 chasis a SE-R. Here's a list of parts you need for this to work:

SR20DE ($400)SE-R/nx2k transmission ($300-400)SE-R/NX2k axles ($60 ea)SE-R wiring harness ($100)SE-R cross member ($100)SE-R/nx2k ECU ($50)SE-R motor mounts($100)SE-R/nx2k gauge cluster($50)$1320(estimation) easily to make your car into a SE-R.

Now by the time you gather all those parts, you might as well sell your car and go buy an se-r for that price. Just crazy trying to piece all those parts together. But if thats what you wanna do, good luck. I know I could make it work, but if you have never worked on your car in depth, leave the task alone. It could become your worse nightmare.

The CA16 came in 87 B12's and from 88-90 they were CA18DE. A few have opted to switch out to the CA18DET, which is turbo charged.

The transmission for the SR has to be used with the SR and vice versa for the CA.

p.s.Stop making several threads asking the same questions. Thank you.

[outcastcat]

Sorry bout the multiple thread effect. You always seem to respond to my posts though with good info. Yea i figured it might look something like that in terms of cost. Its just that in the Northwest, SE-Rs arent easy to find. And at that price, they aint worth shipping in either.

Thanks for the CA information.

Thanks for the b12 info, i wont go that route. I was thinking of buying a sentra as a nice first car, and then swapping in a SR when i had a little (or now a lot it looks like) of money lying around a craving to go faster. But at that price, ill keep my eyes peeled for a SE-R.

I need to read more Nissan Performance Mag. They had most of the stuff you said.

SE-R's are hard to find everywhere, in good shape anyways.

[outcastcat]

Ive noticed. Are the parts for the swap hard to come by? Im thinking ill drive around for a while with the GA (though its nothing special) and then swap in the SR in a couple of years (maybe for senior project, im a sophmore about to graduate thise year). It would make a good first comuter car, and although its not RWD the FWD should take me to the pass to board!

[RED_DET]

THere are a few different places on the web that you can find sr parts. Sometimes you can get lucky and find a wrecked one in the junk yard.

[outcastcat]

The NX2000 stuff fits inthe Sentra platform right? What about B14 parts (200Sx SE-Rs, they fight in B13 right?) that would make finding the parts much easier.

And the transmission problem is only in 91-92 trannies isn't it? or all B13 transmissions?

Random ?: Can the SR20DET swapped into so many 240s be swapped in transversly like the SR20DE into a Sentra?

THe drive train from a NX will work into a B13. Drive trains from the b14 will work also. Though you will get more power out a highport motor(b13, 91-93). B14's come with lowport motors.

And the transmission problem is only in 91-92 trannies isn't it? or all B13 transmissions?

91-93 b13's or NX's will have 5th gear pop out sooner or later. The fix is to use a 95-97 200sx se-r transmission. The problem was fixed late 1994.

Hey i got a question on the old B12s? Is the CA a very good engine. I checked the CA forums but they seem to be mostly about the CA18 that makes it way into the 240. Is the B12 a good tuner car, or should i continue to look into SR b13s (either swapped or SE-R). And can the B12s CA be dropped in favor of the GA, cause it might be cheaper than an SR and if its a good engine the extra size SHOULD make it stronger. Plus there is little market support for the GA16 (although SCC is doing a 200SX buildup on one).

Im looking for a normally aspirated daily driver, that also will allow me to work on it and still be a decent performer. And as much as I like hondas (good cars) nissans are more original. THats what led me to SE-Rs is their good quality and tunability, as well as good solid performance.

With such a daily driver NA SE-R is it possible to run under 15 in the quarter?

[nametakennow]

15s should be no sweat. The car is so light that with the SE-R's SR power 15s aren't far away. I want to say, and I'm sure someone can give you better info, that I/H/E, suspension, good tires, and cams will do it.

http://sr20forum.com/showthrea...+time

The fact is that you don't need S5s to run that time. The power curve on those is so far up top that he wasted enough time down low and in the middle to even out his 1/4 in the end, I believe.

I fully intend to run good 14s with I/H/E, cams, pulleys, high-flow cat, flywheel and street rubber on the heftier B15 (I won't be stripping anything, maybe take out the rear seat if I'm in a bad need of an extra .01sec, lol), and I'd venture to say I'm not far off.

[outcastcat]

Yea with project beater Nissan Performance mag was able to run about a 15.25. Sounds good with what your using, though its pretty thorough, shoudl be good. Is that lightweight pulley's or underdrive? Cause while i might cut some weight (though not lots cause like yours its a street car) i want to keep all the stuff, so no underdrive. Are the lightweight clutch parts needed? Ive heard lightweight stuff is hard on the clutch, so i dont like that idea either. I just want to make a fun first car (its why the goal is only to be under 15). It is a pretty light engine.

Does anyone know alot about the VE (the "VTEC" SR20)? Ive seen a little on it but it didnt seem specific. When and in what cars is it put? Can you take the head off and replace it on top of a DE or do you need to swap the engine (which ive seen done on NPM). Also is it that good (they said it made 20 something extra HP, which is really nice).

[nametakennow]

The 2pc pulley set is lightened and slightly underdriven. It's a crank pulley and water pump pulley. The stock wp pulley has been known to do strange things at high rpms anyway. There's no harm in underdriving those. There's a 4pc set that includes two more underdriven and lightened pulleys. That set would cause some ill effects as far as accessories and such go. That's why most people opt for the 2pc, as I will.

The VE is a later model engine in a few Japanese models, as well as an Australian or two. The VE does make more power, and it's a great option. I'd think that you could swap the whole top half, but I'm not 100% sure, and, now that I think about it, I think it has a different piston setup (slightly higher comp).

I don't know a whole lot about the VE. In General there's an FAQ with the VE listed and a few specs.

[outcastcat]

Im almost certain it sees stateside. Its sold in B15 Se-Rs i think And SE-R Spec V's, and later 200SXs (i just saw 97 one for sale on a different forum with a VE). I imagine that if u coulds swap the cylinder heads itd be done more often, because thats a good deal of reliable power.

The water pulley sounds like a good idea, but does anyone ever make un underdriven parts that are lightened (that would be cheap power)?

And before someone says i need to do research and am being dumb (have a tendency to do), Nissan Performance Mag has a VE swap thats fairly straightfoward worth more than 40 HP (its 187 vs 140)

No, it's not. The B15 SE-R/Spec V has a QR25DE.

Later 200SXs had the second US version of the SR20DE.

I think there is a lightened, non-underdriven pulley, but I can't remember the brand right now. Cheap power? A UR 2-piece set is something like $220.... that's really cheap.

VE swap or VE head swap? Either way, it should be very easy, seeing as it's the same motor, just a different head design (and, like I said, maybe higher-comp pistons).

[RED_DET]

Yes you can swap the head and valve train on a VE and put it on a DE block. The compression is only :5:1 different. So the power would be almost the same. You would still need selonids to switch over the cams. It's going to be very hard to find someone just selling a VE head. I have seen them forsale and the guy was selling them for $600. The VE motor is still relatively new and most that you buy will have less than 20k miles on them. So there aren't that many lying around blown. Great idea, very hard to find.

[RED_DET]

CA18DET would fit into a B12. The car comes with a CA18 from the factory. The motors are older and will have more mileage. But you can still buy parts in the US for the motor, since the NA version was put into us cars. Nice thing about those motors is they rev to 9k. Talk about a powerband.

[outcastcat]

Is CA18 B12 tunign a good cheap route to go or a dead end? Somewhere i thought I saw a B12 for sale with a 1.6, or was that someone miss posting on the web (not to unlikely on autotrader or something).

Yea i just saw a B12 powered by a GA15 or 16. What B12's was it offered in?

Had a brain fart. CA motors came in the pulsar. Should fit into a B12 sentra.

After some homework, I can conclude that swapping in a CA18det into a B12 is not straight up. Frabrication will have to be done and parts mixed and match. If you want to do a CA swap, swap it into the Pulsar. Bolts right up and the CA18's can be had for 400-500 dollars. Like I said before they are older motors but still reliable and decent power can be made.
