The JDM/USDM Roller Rocker SR20DE Info Thread

[swiss]

Well, add PSC Metals to the Roller Rocker registry. I scrapped my motor on Friday. Metal prices are great right now. I got $67 for the aluminum and $14 for the mixed metals. It's a lot of work separating the aluminum, though.

[Octave236]

did you keep a valve cover It's my fault

[swiss]

Yeah, the VC was from a "spraybar" motor anyhow. It even made a brief cameo on the new setup while I got my new VC re-re-coated:

[Scca_Ev]

Just do I am clear, to swap a RR motor for a USDM DE I need to make the following adjustments

B15 oil filter
Swap over the intake
Swap over some misc brackets
Mod the PCV hose to fit the RR valve cover.

I am not sure about the water pump. Will the USDM water pump fit?
What about the dist. Do I swap that over too?

Am I missing anything else?

[swiss]

Yeah, use your stock dizzy. I'm 99% sure the water pump is the same, but you might check with Greg V to be sure. As for the other stuff, you have some options. You can use your DE valve cover rather than reroute the PCV line. You can also use either oil filter housing. The RR would use the B15 filter on the bottom of the back of the engine, the B14 one would of course keep the current location and filter.

Thanks Swiss.. I guess that would mean I need an oil filter housing gasket..

If this new motor is just like the 2000+ 2.0, then the oil filter and water pump are the same according to the parts guides..

Well, I have completed the swap and thought I would add some of my findings for other's that come behind.

Swap was a 96 SR20 to a jap spec roller rocker motor.

Valve cover from the 96 engine will NOT fit. It's too short, had to use RR valve cover.
Right engine mount bracket had to be swapped over from original motor
I used original intake, starter, flywheel, and dist. Installed US spec header, fit fine.
RR Low mount oil filter and oil pan fit fine as did the P/S and alt brackets.

For my swap I removed the EGR and Evap as it's not an on road car.

The only real problem I had was it won't start.... It appears there is a fuel issue. It will run with some carb cleaner, but not otherwise.

I have a couple of questions. Does the fuel feed line go to the top or bottom connector on the intake.

I also think I screwed the pooch when I removed the evap. I am not sure which is the fuel return line and which is the evap line.

Would someone be willing to look at their car and tell me what fuel line goes where and what line the fuel return line connects to on the fire wall?

Sorry, didn't mean to lead you astray. Mine was running a DE cover from the previous owner. Maybe he modified something to make it fit.

The feedline goes from the fuel filter to the rail itself. The return line exits from the fuel pressure regulator.

Not sure off the top of my head on the evap line.

[Scca_Ev]

Thanks for the assist swiss..

I found the problem. It seems a Bosch ABS unit will not run the engine

All I read in the forums said no two connectors are alike so I didn't pay close enough attention to the fact the ECU and ABS connectors are identical and right next to each other (duh)

The engine runs and all is well..

One last question. I installed a real coolent temp gauge. I have seen the adapter that goes between the upper coolant inlet and the hose which is the outlet from the radiator. Wouldn't it be better to measure the engine temp coming out of the engine, not going into the engine?

Just to update some of the dynos... From a JDM p11 2j2 motor.

Dyno stock p11 timing at 13 (motor with more than 200.000-km)


Dyno-2 timing at 17


Dyno-3 timing at 19


Dyno-4 Timing at 20


Dyno-5 timing at 20 plus tuneup( bkr6e gaped at 1,1mm , tps at 0.45 volt ,new rotor , new air filter, MAF reground)


Dyno-6 timing at 20 Hotshot cai ,ground kit,3 inchs exhaust


Dyno-7 JWT ecu,cams s3r,ur pullies,Hotshot cai,hotshot header gen 3,apexi s-afc2 ,apexi itc(timing)2,25 inch crush bent exhaust wrx muffler.


Dyno-8 p11 stock vs p11 with cai,timing,exhaust


Turbo p11
t28 from gti-r
14lbs
3 exhaust
2,25 gtir. jpipe
evo 7 fmic
440 injectors
afc2
itc
avc-r


t28 vs 3071r .86 trim 90 same setup just turbo change... same boost 10lbs both turbos


12lbs 3071r
changes from above dyno
3 dp , 3.5 exhaust
big fmic
b13 ecu 7500 rpm stock everything else



This is another setup sc61 turbo plus many things .. still Stock RR motor

link
http://www.sr20forum.com/turbo/20245...-bigturbo.html

360 whp at 14,5lbs


After that I put a pt67 and boost to 29lbs... *** car puts down over 500whp on a STOCK RR motor...

Now Im under new development of a new setup wich will include... s3r cams.. springs and retainers.. custom made intake manifold .equal leg exhaust manifold.. etc..
I will dyno this setup at 14lbs ... then Im going to forge te RR motor
Hope this helps some.
Good luck people-

I love you JP... Way to represent strong... I had lost these pictures of your dyno's. They are very inspiring.

naa man.. THANKS to you for this thread.. I just put my 2 cents...
cheers

[BRE92SER]

does anybody know the stock RR injector flow rating?

ya... i searched. and skimmed over this whole thread and the injector thread. couldnt find it.

[XxToKeSxX]

The JDM's use the same 259cc's as the regular DE's... nothing special. I believe the b15s use a little larger top feed if I'm not mistaken.

[BRE92SER]

yeah its the USDM ones im interested in. im working on trying a GTI-R manifold on my highport (already test fitted), but i need topfeed injectors that are somewhere close to the same flow rate as the stockers (259)

i read on the QR forums that the SPEC-V ones are in the low 300's, so i might try those.

[sohcvtec06]

dudes....i have the new 00-01 JDM RR and my question is, on the outlaw engineering site for the thermoblock spacers, it says that the spacers are for the 00-01 sentra SE (which i know is a RR as well) but can i use the spacers for the usdm manifold on my JDM one?? someone please reply because i want to order asap.

[Scca_Ev]

I am not sure what these spacers are, but I do know that the JDM intake gasket is the same as the USDM gasket.

Some more data from a stock p11....

stock p11 timing at 12.
