1.6 to 2.0 sr20 motor swap questions

[imbroke420]

hey im buying a 91 sentra 5spd on sunday and i was wondering if anyone on here has ever done the 1.6 to 2.0 sr20 swap. i plan on using the tubo kit from turbonetics on the 2.0 motor but thats beside the point.... how hard is the swap?i've heard that all the motor mounts are the same but i was wondering if i can still use the same transmission, and if anyone knows where there is a write up on this swap. let me know, thanks, eric

[RED_DET]

There is a sticky above this thread. Might be a good idea to start there.

[imbroke420]

the reason i asked this question was because your thread left me confused, bcause ur talking about bluebird motor this and that i dont know man its really hard to follow i was just wondering if theres anything more specific to the na motor. thanks

[nametakennow]

It's the exact same process for a Bluebird/Avenir (turbo motors) as for NA motors. In the sticky he does a pretty good job of clarifying where it's different in terms of equipment needed (for instance, you need an NA ECU for an NA swap).

[RED_DET]

Item:U12, U13 and AVENIR SR20DET/USDM SR20DE/JDM SR20DEDescription: 2.0 liter turbo motor or 2.0 liter Naturally Aspirated motor.

Those are the first two lines from the sticky. I don't see the confusion. I am glad to help in any way I can. But when things are right in front of you, then I become confused.

Going from 1.6 - 2.0, the info applies to anyone of those motors listed above, whether it be turbo or NA.

ok, if i swap my ga16 for a sr20VE then is ther anything else or diffrent i will need? also doesnt the sr20ve have a 6spd trans?

[nametakennow]

The SR20VE will mate up with whatever other SR trans you have.

Regardless, the swap for a VE is the same as for a DE or DET. However, engine management is a special issue in this case because of the VVL.

[imbroke420]

okay, got it now. sorry boout that.

[imbroke420]

sorry one more question, a little off topic, but anyways, if i get some nice rims and then have to replace the axles when i do the swap, do i have to change the hub or whatever along with the axle or is it just the actual axle that i will be replacing, or does it not matter and they are the same size and whatnot. never played around with this stuff before so i wouldnt know. just dont wanna pay for rims if im gonna need different ones in the spring time.

[RED_DET]

Axles only. B13/B14 hubs are what they are, regardless of model. So as long as you get wheels with 4x100 bolt pattern and right offset, you are good to go.

[Nikku]

RED_DET, is there a set place on line, or a local place ( since we're both in Louisville ) that will have cross members, motor mount brackets, etc, i plan on swaping my ga16 in my B14 sentra for a sr20ve as soon as summer rolls around.

[nametakennow]

Check junkyards for junked SE-Rs.

Hit up Google and run a search, there are lots of sites that are essentially junkyard networks where parts can be indexed and actually transported from one yard to another if needed.

You could also try your luck at a dealer.

[RED_DET]

The best places local are Grade Lane Imports off Outer Loop and Alberts Imports which runs off Knapp lane. Knapp lane is off Grade lane in between Outer Loop and Crittenden Drive.

I have done the 1.6 to 2.0 swap in a b14... So if anyone has any questions feel free to hit me up! I'm always glad to help out and add in my 2 cents [email protected]

[Nikku]

RED_DET did you do the swap yourself or did you have it done by a professional? I dont know to much about cars, infact i know very little. the only thing i have done is installed a CAI, Do you know of any places around here that will install the engine for a good price? what should i expect cost wise?

[Mr. MoNkEyS]

ive actaully got a question. i plan to eventaully do a ga16 to either sr20det or sr20ve if i can find one. gonan try to see if i can do it myself or if it too hard ill let a shop do it, but my question is, i have aroudn already 254k miles on the engine and chassis, how long is a chassis good for? would there be any forseeable problmes if i were to swap in a sr20? theres been no damage to the chassis as far as i noe, the only damage is a lil dent in the body.

[RED_DET]

Yes I did my swap and I have done 6 other JDM SR20DE swaps. I didn't go from a 1.6 though, I already had a SR motor to begin with. Which made things alot easier. Your problem is going to be sourcing all the SE-R parts you will need to convert. There are a couple places local I'm sure would be willing to take your rmoney, but they are going to charge an arm and a leg. If it wasn't so involved, I would do it for you. Normally in this situation, I always tell people its easier to sell the 1.6 car and find a SE-R and swap in a fresh motor.

[RED_DET]

The only real problem you need to worry about on the chasis is major rust damage. Aside from that, the suspension components should probably be upgraded including, struts, sway bar bushings, ball joints, etc.

[Nikku]

hmmm, what do you mean "so involved"? So you recommend selling the car and finding one with an SR already in it? Is the hard part finding the parts to do the convertion? or installing them? Thanks,

[RED_DET]

The entire process is involved. Sourcing all the parts will be the biggest PITA. Then swapping all the old 1.6 parts to the 2.0 parts will be quite time consuming. The wiring harness won't be a walk in the park either. By the time you find and buy all the parts you need, you could sell you car and buy an se-r for a cheaper price. Then a motor swap is 10hrs away. So for some one to do the 1.6-2.0 swap for you, they are going to bust your head on the price and IMHO, its not worth it. List all the parts you NEED for the swap, add up the total and you tell me what makes more sense.

[Nikku]

uhhhhh. gay, i really hate shopping for cars. but i unno i might have to sell my car n-e-ways ( might be moving to japan in April, then i can get myself a Skyline GT-R ) w00t, J/K. its so hard to find a good car. i think like 95% of sentra's have a GA16, o well,

Chris859, how much did it cost you all togethor to do the swap?

[Chris859]

Unlike red-det said, the harness is a walk in the park - it all plugs into the 1.6 dash harness stuff, and drops right in. Sourcing all the parts really isn't all that hard either...

A quick breakdown on prices I paid...

95+ JDM sr20de(they actually sent me the newer '00-01 rollercam sr, not what I prefered, but I used it anyways) $675 shippedSr Axles ~$150SR radiator $100'98 200sx se-r transmission $100Jgy 8.5lb flywheel $269 (While I used the jgy, you can use a stock se-r flywheel for less money)XTD stage 3, 6 puck sprung clutch ~$150 (I love it, and its still holding up after plenty of hard driving, great clutch for the money)Misc mounts/brackets ~$350I got my ecu from a 95 200sx se-r for $30misc belts, hoses, etc were another $100 or so.

On the harness I made a custom harness out of a bluebird det partial harness, ga16 harness (ecu/dash plugs side), and a couple misc others I had laying around... (only recomeneded if you are highly experienced with making custom harnesses)

If you had to buy the whole harness, All you would need is a b14 se-r harness, it will be direct plug and play with the dash harness. Jgy sells the harness set for $449, which is all the harnesses you need for a drop in install.

Depending on where you get your parts, and how new of parts you want... you can most likely do the ga to sr swap for somewhere in the $1,000-$2500 range. The swap itself is actually really straight forward - if you know what all has to be changed, and are capaple of removing/installing an engine and transmission you will be fine doing this.

I bought a '97 200sx se that used to have a ga16, with no engine, trans, or drivetrain parts - and put an sr in it. I recently sold it to one of my friends that needed a car for just under $3,000. If anyone around here wanted it done I would do it for a fair price, and could most likely complete the conversion in one or 2 days assuming I had all the parts.

The axles you need for the swap depend on which transmission you go with. If you go with a non lsd b14 trans like I did you can actually use a ga16 axle on the driver side (what I did, just a new axle), and a normal b14 se-r axle for the passenger side. Anyways, feel free to email if you need any further explanation, info or recomendations.

[RED_DET]

So with that being said, you can buy SE-R's all day long for 1000-1500 with a SR already in it.

[Chris859]

se-r's for $1-1.5k all day? Must be nice! Not here... Here you might get a crappy condition b13 se-r with over 150k miles for that, but no way will you get a b14 se-r for under $3-4k, nor will you find a b14 se-r with a drivetrain under 40k miles for that price. But hey - to each his own. I would personally rather do the swaps, and conversions - thats part of the fun. Working on my cars is a hobby to me, not just a ride to the grocery store, work, etc... It keeps me busy, and poor As said earlier, around here it is cheaper to do the swap than to get an se-r, of course that will vary depending on where you live. Once again, as with anything else regarding car modifications, to each his own - I would rather make sure people know it is a do-able swap, and an option - rather than to just automatically tell people "its too much money, and a huge involved conversion - just get an se-r instead!"

[RED_DET]

Well unfortunately I tell people how it is!! For someone that has never done an engine swap, then obviously doing this will be quite involved and someone will need alot of resources. End of story. If you think I'm wrong, good, but my opinion is what it is. If the swap was so common, more people would be doing it, but they don't. Unless you can find a donor car for all the parts you need, you will NOT be able to resource them all in one place. I don't try to sugar coat anything, you tell people oh thats an easy conversion, yeah, if you have done it before. But you have to consider alot of people don't work on their own cars and rely on others do to it. Therefore if a shop was do to this conversion for you, it will be an a$$ rape on the price. It will be double the price you quote. So if somebody has 2-4K laying around to swap there car over to a 2.0, then hell, knock yourself, best of luck. So as I said in my earlier post, it's not WORTH it to me. I never said one time the swap wasn't possible. I know the swap is possible, my name is by the sticky.

Hey, if i offer you a resonable amount will you help me with it? i can prob get all the parts, it would just be the install i would need help with. It would be sometime in July if i was to do it.

[RED_DET]

Yes I can.
