What Does That Mean?: IM = Intake Manifold VC = Valve Cover RR = Roller Rocker CW = Counterweight B/N = Between
How did you get a JWT ecu to work w/ the RR? I must be mistaken but, I didn't know they could crack the code for a RR engine. Can you elaborate what restrictions/programs you had them change. And lastly, is this their ECU or your reprogrammed ECU.

Damn, 16 psi, I wonder what your numbers are...
Impossible, im sure he has the older intake manifold or wired in a different harness (PITA)
I called JWT and told them to program for the following:
Z32 maf
5 speed
50lb injectors
10 to 1 compression
turbo application (any turbo)
asked to program on their 96 ecu as I need an OBDII so I can send mine later
I did not told them it is an RR. I didn't believe they needed to know that and to my surprise they never asked what motor either. I told Ben @JWT that the motor is something other than 96 but not what type.
After installing the new ecu, I had hesitation all over. I bought new plugs, gapped them at 0.30 (same as an mr2 turbo), bought new distributor rotor, distributor wires for a 96 200sx se-r from Advanced auto parts.
So far, no problems, no hesistation, no detonation and no cold start issues.
During the whole setup, I had some serious help from a buddy of mine who is an electronics/motor guru (the word guru was used for lack of a better word!).
EDIT: Yes, the harness is an OBDII from 95 up. Same with the intake manifold EDIT: My timing is set at 15 degrees
Here is an older unclean embarassing picture. Before I switched to a proper z32 plug (maf is in the pic), stock boost guage return line from the actuator and distributor wires.
The above is a debate on which is a "better" designed crank. From reading it there are different views upon the benefit of each case. Coming from an engineering standpoint: Less rotational weight obviously means there is less energy required to rotate the mass, which results in an easier ability to rev. I really don't think that this is a main issue for N/A vehicles that are used for daily driving application, but for cars under heavy use, and high RPM (racing for long periods of time), the issue relies on the durability factor. The discussion is very interesting and their seem to be a lot of educated views upon each side.
This doesn't affect my car, I will not be using my car for racing or anything of the sort. I also will not be turboing this vehicle.
Are you serious! I did it myself! Nothing too technical, just so people can understand the design. I work in 05/06 at work, but since I'm in school I'm only working in 04. I have a friend who has a copy of 04 Land Desktop as well.
Went outside to take some measurements and came up with this! I think its pretty close to the scematic. I hope that it holds up, I will keep it in my room until the Valve Cover is painted. When I switch the Valve Cover over is when I'll do the first oil change (250-275 miles) after the swap... Here you go...
Peace,

I think that my motor came from a late 90's n15 Nissan Almera (Gti) I have a hunch, there is no way that my motor could have come from 00-01 because of the engine code 1st page. It may have still come from a Primera, but I now have two suspects This is interesting... I will look more into it. But here is a pic of an N15 Gti Engine Bay to compare... Interesting...
Here is my current bay, post JDM RR Swap (w/ USDM IM Swapped)
Here is n15Gti's Non-Stock Almera GTI Bay... I hope he doesn't mind me using this for comparison, but they come with RR's as well... They are mainly in the UK, but I believe they are just called Pulsar's in Japan, I'm not sure if my engine is from Japan or UK? Who knows?
Here is what the JDM looked like Before Removing the JDM IM, similar to P11, and Almera GTI

Yeah, I thought that was the only path from where this motor came from... I thought for sure it came from a P11, but I didn't know the Almera had it as well.
I want to find out for sure somehow... I need to check peoples engine codes... I need more people to sign the roller rocker roll call to find out.
The The Almera GTI comes with a roller rocker, thats what I'm talking about...
I'm not talking about the Mods, I'm speaking of the Engine... What do you mean?
EDIT: Oh I see... I meant the GTI came with a RR engine stock, I'll correct that...I type too fast... Good Eye, Thanks!
The Almera GTi (N15 GTi) came withe the roller rocker SR20 in 1996.
It`s produced from 1996 till 1999. It has the same engine as the P11 GT but the only difference is the country of manufacturing. The P11 GT engine has a UK stamp behind the distributor and de Almera engine hasn`t.
My engine is slightly tuned:
SSAC Header
PR CAI with K&N RX-3900 filter
Unorthodox Racing 2pc. Pulley Kit
2.25" Catback
Catalyser removed
Timing @ 17
Denso Irriudium Spark Plugs
Mobil 1 5W-30 oil
No S-AFC or other managment device.
Without the catback and pulley-kit it had 180.3BHP.

What do you mean?
are you trying to purchase it?
