Project B12 SR20DET - Page 2

I'm a student myself so I understand the budget thing. The engine harness is the only wiring harness you need. It connects to the engine and goes about two feet into the firewall where it connects to the ECU. I always see SE-R and DET wiring harnesses on the classifieds for SE-R.net, sr20deforums.com, and here. http://classifieds.se-r.net/ForSale/...neId=CO3X99NSA This is one I found this morning.

I believe this is all the parts you need:
Engine (91-94 preferrably) w/ mounts + one body mount
Transmission w/mount and LSD (91-97)
Axles (make sure they match the trani)
Wiring harness
ECU (91-94: no OBD crap on the 95+)
Crossmember (i've seen a few for sale online somewhere also)
SER Brakes (optional: you can press replace the b12 hub with a b13 hub and use the b12 brakes)

Just keep you eye out on the internet for people selling these parts. Junk yards will always be really high in price. You may want to Chris at sr20development. He has a garage full of Se-R parts and maybe able to help.

good luck

how did the axles fit on the b12 disc brakes??? do they need machining or do they bolt on the b12 disc brakes???

regarding the enginew supports, did you move any of them???

regarding the engine brackets, did you fabricate new ones or you used the same brackets??

how bout the rewiring of the harnesses??? is it a nightmare???

is the sr20de tranny cable type???

does the sr20ve bolt the same in the b12 as the sr20de???

I have a couple questions about the stock suspension on a B12. After reading the "Project B12..." article, I thought that you'd be the best person to ask.

A friend of mine has an old B12 that isn't in very good condition. The suspension, in particular concerns me. She said that she had the struts and springs replace not so long ago, but the car rolls WAAAAAY too much around even the slowest corners. Changing lanes at freeway speeds is down right dangerous! I'm sorry, but I don't know the trim level of the car. I hope that doesn't make it difficult for you to provide me with any information.

She asked me if I could drive and take a lot at the car to see what the problem was. After driving it, I immediately thought "sway bar". I looked underneath the car and was surprised to find that there was nothing even remotely resembling a sway bar.

My questions are as follows:
1. Is there supposed to at least be a front sway bar on the car.
2. If not, is there something else that is supposed to minimize body roll. If so, what is it and is it easy to replace?

Thank you very much for any help you can give me.

the sentra has both a front and rear stabilizer bar. I couldnt imagine why one would be missing though. Is it the front or rear?

hybrid DET · Jul 15th, 2002, 11:38 PM

from what car and what year did the sr20de you use came from???

The sr20 in it right now is from a 93 model.

what tranny did you use?? is it the tranny fom the same engine and same car??

The trani came from a 93 model as well.

regarding the axles, did you use the se-r axles or what??

The axles are from a 91 sentra se-r. Do not get the 95+ axles!

how did the axles fit on the b12 disc brakes??? do they need machining or do they bolt on the b12 disc brakes???

I used the se-r front brakes, they bolt into the b12 suspension just fine.

regarding the enginew supports, did you move any of them???

I dont understand what you mean. All the mods i made to the engine mounts are explained in the article. None of them are bolt in.

regarding the engine brackets, did you fabricate new ones or you used the same brackets??

Look over the articles. They explain all the fabrication involved in the swap.

how bout the rewiring of the harnesses??? is it a nightmare???

For me the wiring harness was. The main problem lies in connecting the b12 wiring harness to the sr20 harness where neccessary.

is the sr20de tranny cable type???

There are some that are hydraulic but dont get those. Be sure to get a cable trani.

does the sr20ve bolt the same in the b12 as the sr20de???

I believe so, if chris at sr20development wants to hand one over to me I'll find out for sure.

my plans had change butr not still sure...my friend here int the phil is an importer from japan, i asked him if he could get me a sr20ve font clip from japan. he said ihe can get me one so im planning to get a sr20ve and use a sr20de tranny...hope he's gon na be succesful in finding one...

If you get your hands on an entire front half (body included) it will give you just about everything you need. I've thought about doing the same swap lately but at this point it really wouldnt be benificial to the project.

It must be missing both, because I see no stabilizers under the car what-so-ever.

And just so there's no mistaking, I believe I know what sway bars look like. I have a '90 240SX and I just pulled and then reinstalled both my front and rear bars. I have also seen the sway bars on my friend's B14. I'd imagine the bars on the B12 should look similar to those.

Any online B12 parts microfiche that I can look at?

Maybe I should just go down to my local dealership and ask the parts guy...

Thanks for the help!

THANKS FOR ANSWERING MY QUESTIONS! I HAVE A COUPLE TO ASK YOU AGAIN...: )

I used the se-r front brakes, they bolt into the b12 suspension just fine.

BUT I DONT HAVE THE SE-R BRAKES...I DONT HAVE PLANS YET ON UPGRADING THE BRAKES.
CAN I USE MY STOCK DISC BRAKES???

BIGTOM ON SR20DEFORUM.COM TOLD ME THAT THE SR20 SE-R AXLES FIT THE B12 BRAKES. BUT WE DON'T HAVE SE-Rs HERE IN THE PHILIPPINES!!!
CAN I USE OTHER SR20DE AXLES FROM OTHER CARS LIKE THE NISSAN PRIMERA???

There are some that are hydraulic but dont get those. Be sure to get a cable trani.

AS IVE SAID WE DONT HAVE SE-Rs HERE IN THE PHIL. IS THE PRIMERA TRANNY CABLE TYPE??

TNX....

Who is bigtom? Tom from sr20development? Well the se-r axles do not fit into the b12 brakes unless you press out the hub and replace it with the se-r hub. That is what Nismodriver did instead of upgrading to Se-r front brakes.

I'm not sure what type of trani the primera has. You'll have to investigate into that a bit. Also try to stick to the pre- 95 axles. The 95+ axles are about 3/4 " longer and may cause you some trouble in the swap.

I would go to the nissan dealer and check there diagrams. The front sway bar should connect to each control arm and the rear should connect under each drum brake. If you're still dealing with it by this weekend I will take a picture of the sway bars and post it for you.

good luck

***** I think I can help here. The cheapest model B12 Sentras, [known as the Sentra Standard], don't have a front sway bar from the factory. I have owned and driven several. Even without a front bar, they don't handle too badly at all. You must have some really bad lower control arm bushings, for the car to dart all over the place in a turn. This is common on high mileage B12's. If you want to put a front bar under it, it's easy. The mounting holes are all there. All you have to do to install one, is get one from another B12, and bolt it up. All B12's have a rear sway bar, as they are incorporated into the rear suspension. They double as a locator for the fore-aft movement, and as the sway bar. The bars on a sport coupe are larger in diameter than the sedans. They are the ones to have. I hope you find the handling problem[s].

bigtom is an "se-r nut" in sr20deforum.com, i do not know his real name, he is from san diego, CA also. ah ok...so i have to replace them wd the se-r ones. the se-r your talking about is the b13 right. does the b13 SE(GA12de) have the same hub as the b13 SE-R ?? if yes then i can get those. if not maybe i will have to look for the nissan altima disc brakes here in the phillippines.

how do i know if the axles are pre 1995??

thanks again...youre really a big help....

I believe the se and se-r do have the same hub assy. I'm not sure how to tell the difference between the two types of axles. The 95+ are only 3/4" longer but thats's really not visible to the eye. Just specify 94- only.
