allot of people on the Skylines Australia forums love the Veilside single tb one. but others that don;t want insanely 700HP cars, just get the Greddy plenum and keep the ITB's (that fixes the starvation to cylinder 6)

-----------------------------------------------------------------------

rb20det Engine variations:

The rb20det came in two different forms, the earlier red top with the NICS system and the newer silver top version with the ECCS system. The red top is the earlier version of the rb20det and came as standard with the r31 skyline, z32 fairlady and the nissan laurel, whilst the r32 skylines and nissan cefiro came with the silver top version.

Just to confuse you more there were a few red top rb20dets with the eccs system, heres some engine power outputs.

RB20DET red top
1986-1987: 178bhp (NICS version)
1988-1989: 190bhp (ECCS version)
RB20DET silver top
1989 onwards: 215bhp

-------------------------------------------------

Resetting the rb20det ECU:

You can reset the ecu by disconnecting the battery and then pressing the brake pedal in for a minute or so, doing this tries to light up the brake lights and removes all of the voltage from the ecu, then connect it back up and go for a drive. Make sure the front wheels are straight when you do this or else the hicass can get a bit screwed up because it thinks the wheels are turning slightly.

The ECU has the mapping for the fuelling this wont change but the timing and airflow is monitored all of the time and adjusted according to conditions if you have been using low octane fuel or carried out recent mods then you'll benifit from the ECU reset as it relearns the optimum settings and changes the timing in very large increments initially then as it gets closer to being right it narrows the adjustments down.

The ignition timing is advanced until knock is detected and then pulled back in narrowing swings above and below ideal until it has narrowed it down to being ok. Once settled it almost stops learning and will use tiny adjustments each time you go out and take a lot longer to get to its ideal each time.

Also all jokes aside. With the S13, there is not enough clearance to run dual pullers, especially if your running air. There is, also limited room to attempt a dual pusher setup on the front side. Hence the push pull setup.
The s14 has a much larger front area, allowing for dual pushers.

P.S. give me a call ken I got a plug I need to send to you.
with the radiator moved forward there is plenty of room for dual pullers

buy everything from SYKO,

"trust me" when i say this.. products + service + support, and everything related to SYKO can only be classified as "TOP NOTCH"

There is no need for you to think twice, just get it.

rb's create alot of blow by. I installed a circuit sports catch can to remedy this problem but I didn't reinstall the restrictor plug in the intake line. My catch can overflowed and I had spy-hunter smoke screen coming out the tail pipe. The restrictor plug is a cylinder shape that fits in the intake line which is about .5-.75" long has a diameter of .5-.75" and has a 1/8" hole in the center. This reduces the vacume pulled from the valve cover into the compressor. My buddy is machining a new one for me and will be installed tomorrow. After there should be no more spy-hunter.

If you want to know where exactly the plug is just feel for a hard bump in the flex line going from the exh. side valve cover to your intake pipe. Your not going to push that thing out so you will need a razor blade to cut it out.

I hope my lesson helps others from my mistake, I thought my turbo was done. Sorry for the repost but this is the best place for this info.

That was turn key, i added on the radiator to the total price, i forgot to add in the $$$ for that one, but i got all the stuff last fall when a lot of places were working on getting rid of their inventory. and had a couple of hook ups that helped shave some cash off the price. needless to say i did all the work myself plumbing and all. Also i spend months researching before the first time i did this so i knew the right places to go.

Dude, this question has been answered already. People who ask this question are not serious about the swap in general anyway. If you do your homework and make the calls you won't have to ask.

My friend is doing a 5 sp conversion on his Automatic RB25. Iam looking for a pilot bearing for a RB25DET block.

Does anyone know if it is the same Nissan part number as a 300zx?

I was hoping i could just run down to the dealer ship and just pick one up instead of waiting a week for Phase2.

Whats up guys just wanted to know what the parts avaliability (can I cross reference most of the oem parts like the sr) is for the rb25. I can get a rb for $150 more than an sr, just weighing my options. Only thing that is really making me lean towards the sr is finding parts.


Also is their any particular year I should get I read something about the crank journals on the older models gave out at 300 hp.
