Rb25det swap... Need help!!!!

Recommended Posts

Guest 71rb240z

Hi everyone, i have a few questions regarding my rb25det swap:

 

-What model of sds system you guys use?

-Other then the system itself, what other parts is needed?

-Do all the sensor from the engine works with the system?

-Where can i buy one for the best price?

-Where is a good place to place a fuel catch tank?

-Is it necessary to change the fuel tube size from the tank to the

engine and fuel return line from the origional fuel set up? (240z)

-My engine didnt come with a power transister unit, instead it has is

two plugs connected to each other, i was wondering if it's necessary

to have one to make the car run.

 

Any help is appreciated!!

 

thanks

Simon

Check it out guys, heres the answers from the RbZ master guys:

 

From stonehac:

 

I use the F system... there is 3 systems for a 6cyl (E, D and F) The

F SYS control fuel and spark, the d system is the same it just dosnt

come with the coil packs and you have to supply your own. and the E

sys is either fuel or spark only i cant remember.

 

If you order the F system you get all the sensors you need to get it

running. It replaces all stock sensors.

 

You can buy one from SDSEFI.com adn any one of there dealers listed

on the page.

 

Fuel catch tank? are you talking about a accumulater in teh pressure

side of teh line or an actual catch tank for a fuel cell? There are

some pretty good drawings on how to build and where to install a

accumulator on the sds page. all you need for a cell is a vent line

 

I did not change my fuel line im my car and it made almost 400 rwhp

It is the equicilent to -6 line so it should flow enough for anynear

stock configuration i would think.

 

If you use SDS ( highly recomended for the Z swap) you will need

nothing from the stock harness.

 

From Matt:

 

If you’re swapping in a RB25 and decide to go with SDS, you will need the EM4-6F. I recommend getting the system to run MSD DIS4 and keep the stock coils. It makes the install much cleaner. The stock fuel line and return are adequate to 700hp. You will need an inline fuel pump and filter. I recommend Bosh pumps. Your stock tank pick up to the pump should be fine. If you need a surge tank (I think that’s what you ment?) for high G cornering, You will have to put it in the trunk. To race on any track, it will have to be bulk headed from the passenger compartment. Look in your area for a dealer. If there isn’t one, you can order from me or directly from SDS.

 

Thanks a lot guys for clearing things up for me!!

Anyone know whats up with the power transister unit? if i install the

SDS unit, will i still have to stress about that?

 

Can anyone post some pics of their fuel set up?

 

Also on the sds unit, i checked out the website and it said somthing

about the TP sensor, can i keep the stock TP sensor or need to do the

magnet setup they provide?

 

About the MSD DIS4, i can use it with the stock coils on my engine,

correct? Any difference between the SDS setup? Also which is cheaper?

 

Thanks ALOT guys, really appreciated!! :lol:

I am using the AEM EMS. I am also running the CDI and wide band uego. I am an engineer for them so I get a good discount (free). If anyone is interested in running this system, I can send you the base maps for the RB25 as soon as I get the car on the dyno, (hould be in about 2 months). I am using all the stock sensors and wiring harness, I just had to set-up the pinouts on the EMS.

does your RB25 have VVT and can the after market EMU controll it?

There is a picture of a fuel pump set up on the RB26DETT group. Look in the installation folder.

I'd like to know the list of basic parts needed to put it in. I know when the time comes you will have to get other parts to replace broken crap etc. But I've tried to do some searching on it and I can only find vague lists of what to get. I guess I would just need to talk to someone whos done a rb25det swap.

 

Figured I'd say that here, so A) I dont start a new thread and annoy people and B) this is a relevent topic.

Did you ever capture your base maps?    If so I would love a copy.
