It is a long story but in brief I purchased a U13 motor with precision SC61 turbo, protec manifold, aftermarket fuel rail w/ precision 720cc injectors, 3" downpipe and 3" intercooler piping.

The reason I purchased the motor was more or less for the built bottom end for reliability purposes. I really do not intend on laying down the horsepower this set up is capable of. Please keep in mind I have not install the new motor as of yet. So, if you have any suggestions that I should replace while the motor is out please let me know.

Anyway, I want to bring it back down to a semi-stock setup. So, I have already purchased a U13 Manifold. My questions are below:

- What are my choices of turbo's (T-25, T-28, etc.) I can mount to my U13 manifold?
- Should I stick with the 720 cc injectors or go with the 370cc injectors?
- Will the injectors from a Z32 work on the stock fuel rail from a SR20DE?
- The precision turbo mounts on top of the manifold, does that mean I need entirely different downpipe and J-tube?
- I assume I will need the stock water and oil lines, correct? Is there anywhere I can get new/aftermarket water and oil lines?
- I have 3" intercooler and piping will these work with my new turbo setup?
- Can I run the Nismo Adj fuel pressure regulator with the new setup or do I need to go with a SARD or Aeromotive?
- I plan on running a SAFC II, I assume I can stick with my stock ecu, correct?
- Would the recirc BOV that JGY sell work with my new turbo setup?
- Will my stock MAF work with my new setup?

Thanks in advance,
Brian

I'm sorry but what the hell is wrong with you. why would you down grade. Thats just my opinion but an sc61 just about owns any motor. With the money it would take to bring it back "stock like" you could buy a p11-b15 tranny and not worry about a thing.

this is going to be my daily driver. Also, the turbo is not in the best of shape - probably need a rebuild.

all of ur questions have been answered you just need to search

Is the motor going on ur B13?

It would be cheaper & easier for you to buy a new T3/T4 ($500shipped) and a Z32 maf ($125shipped) and a Calum ecu ($130)...that's just my two cents

Yes, the motor is going into my B13. I have tried to search however I can't seem to find the exact answers I need. I don't think many on this forum have a SC61 setup and trying to downgrade while salvaging the parts I do have.

I am thinking of selling the entire setup, the member that I purchased this setup from assured me he was boosting a steady 30psi making 545 fwhp. I just don't have the axles, trans, etc to handle this horsepower. As I said this is my daily driver and do not need it to break on me. Plus putting to many miles on my Z right now.

Ok, I did some more searching last night, as I mentioned I can't seem to find an exact answer to my questions. I assumed that the questions I asked were simple for some of you experienced swap guys. Please help.

problem is I will probably have to rebuild the entire turbo due to shaft play, seal leak, and badly chipped compressor wheel. Plus, I don't want to risk breaking the tranny with too much horsepower.

On a side note, how much do you think it would cost to rebuild the turbo?

$250 to rebuild the turbines. There's a lot of users sending theirs off to this place for rebuild. Can't remember the name, but I'm sure someone can chime in.

Oh yeah, and keep all your stuff! No sense in going BACKWARDS! The ONLY way I would take a forcefed monster out of the engine bay, is if I got bored with it and decided to go VE.

I agree just cause the motor CAN handle 30psi doesnt mean you HAVE to run 30psi. I think 8-10psi on that turbo is very nice. As far as tranny issues well thats alot to do with driver and suspension and wheel hop and all that Jazz. On a side note i'm on my 3rd tranny because of a T25. It's all in the driver and how well you built your car. Worn out stock motor mounts and control arm bushing could be the end of a tranny. The turbo could most likley be rebuilt for cheaper than getting a rebuilt T28. Then you wouldnt have to change everything and keep your setup. I would love to be able to afford a sc61 setup.

Guys, take a look at my other post I just made with pictures of the turbo. Let me know what you think.

Uhmm...Dude, you got screwed according to that other thread. So many things went wrong, it's not even funny.

Buyer beware. I'd be double checking my paperwork, etc, to ensure that you're covering your ass, and then I'd sue the shipping company if they don't try and resolve this issue.

Put it this way...

I've got a near set up engine wise as you do and I'm not known as the SC61 master for nothing.

First time in the car at 13psi (mind you the efficiency on the SC STARTS at 15) I nearly **** my pants and screamed like a little girl.

If you have ANY questions about the SC61 I'm the person to ask. I may sound biased but you will NOT find a more efficient and good "big" turbo for the SR than that one. I say spend the money to get it rebuilt and be happy. I can drive the car normal all day long without breaking a sweat. (Well, A/C is out but I disgress).

Anyways, don't go backwards on your setup. You'll regret it. Don't ask me how I know.

Cheers-
Erich
