Super top secret build

[luvemfast]

Now I have your attention.

I have a few random questions that will make no sense to most, but stay with me as it will all come together...........

 

What triggers the ignition on RB's and where is it? Can I control it with ECU?

 

What bell housing tilts an L series to the opposite side of the engine bay? I beleive an FJ makes it straight?

 

Who has some details about a dry sump on an L series?

 

Anyone have an electric water pump on their L series or RB?

 

Any such thing as VVT on an RB?

 

I will have more questions in the future, this is a starter......

 

Thanks, Simon

The cam angle sensor on the front timing belt cover of the RB triggers the coil igniter which then fires the coil packs.

Second one not sure..

I have seen a dry sump on a L series. Tom Cantwell's 240Z with L28 and Motec

Later RB's came with the variable cam on the inlet? side.

That's all I can help with at the moment!

L series electric water pump

I think VVT is on RB Neo Engines and maybe R34 RB25's (Series 2 RB25's)

Ask those RB questions on Skylines Australia, They should be able to give you definite answers

 

I am pretty sure is is the CAS sensor on the front of the engine that triggers the ignition on a RB engine. this sensor is mounted on the front of the passenger side cam.

 

I am not sure which bell housing would do that, have you looked at 180b's etc? If there is enough clearance with the tunnel and the starter motor bulge on the bell housing you might be able to modify your engine mounts and gearbox mount to suit.

Thanks, could have done a search for it but I was heading off to bed and thought I'd just put it out there.

 

Had a feeling there was a CAS on the front.

VVT is good to know.

 

Where is Tom's old car now days? Is it at *** *********? edited

I think it moves around due to some reason is what I've heard. May not be a good idea to post on the forum..

Hi Simon,

 

My RB30 with RB25DE head is running VVT, as Dimitri mentioned on the inlet side.

[RBZ 260]

yeah rb25det and neos have VVTi on intake side. u can see the bulge on the right side. if u not runnign stock ecu or Apexi power FC most other brands i dont think they take advantage of that.

 

not sure about the relevance of L series housing for RB.

u using RB block? or want to adapt to RB head to L block.

or u trying to fit an L gbox behind an RB?

if last one just use an RB box. lot easier and lot stronger than the L ones. though if space is an issue u can opt for rb20 box

 

 

 

[Scando]

What triggers the ignition on RB's and where is it? Can I control it with ECU?

 

As the others have said, CAS on the front on most RB's with the exception of the RB30 where it is in the dizzy.

[Hunter]

scando just to confirm there is no twin cam rb30 motors out there?

[FuzzyDropbear]

There aren't any from factory. You have to swap the heads with an RB25 or 26.

[Hunter]

just as  I thought. If I put an RB25 head on an RB30. would I be able to keep the dizzy ignition to run triple webers on the engine?

[Zedman240®]

Nope, the single cam RB30 head has the dizzy; you will have to buy a MSD device to run a coil pack from the CAS. I don't think its at all hard to do..

 

You may need one of these..but email them to make sure!

Thats the super top secret part......... for now 

Just gathering some info, think of it as homework for a student.

If this was to get done, it would be the first I know of. And totally insane too!

If you really want a project, go and talk to '1 fast z' on hybridz about 'making' a DOHC head....

LOL...

 

love secrets. seems few of us are having them on the forum at the moment. "the evil masterplan........"

 

good luck.

 

looking forward to the mad creation.

Not sure if this is what you're after and it has been discontinued but v-cam from hks is what I've heard being used for those after vvt on the RB also i saw a dry sump system on import monster for the Z's awhile back it would be easier to construct your own though here are some links for v-cam.

That involves welding x 2  4cyl heads doesn't it?

Your on the money though............

Dimitri the MSD system sounds a bit better than the megajolt as the megajolt needs a 36-1 wheel mounted to the crank shaft or harmonic balancer. Simple enough, but if MSD make one that will use the standard equipment on the engine that would be better.

[Zedman240®]

I tried to find details about how or what kind of trigger it needs but you may have to email or call them up to find out if it will work. I downloaded the instruction manual but it just shows trigger inputs from a factory loom of some car. Best to ask "I have a RB25 with a wasted spark coil pack (3 coils) and original CAS. Which MSD unit will work?) for example.

[Hunter]

sent the message before I read that message dimitri, but it was along the lnes of what you wrote thanks mate.

[NZeder]

Ok since no one as really answered the bellhousing question.

 

Ok from this you want to lean the L6 block the other way or at least stand it up straight for some kind of crossflow setup

 

Find a mid to late 80 Nissan that is powered by a Z series 4 cylinder aka navara ute, 910 bluebird (last of the rwd) and there should be a z20,z22 or z24 between the struts.

 

So why a z series bellhousing? Well the z series is based on the L4 (L20b) block with a cross flow head and the engine leans the other way. Hell the engine mounts might work too

[mtopxsecret6]

the rb20de/t do not have vct, the rb25de/t do. So r33 motor and up is what you want for vct, not vvt, its a nissan, not a toyota motor. The crank angle sensor runs on the exhuast side or the head, and the vct runs on the inlet side of the head. You can bolt the non vct rb25de(r32, not r33) head straight onto an rb30 block, though  it will not be vct. You can bolt later model rb25/26 heads on, though you have to weld up oil/water gallaries, and re drill new ones, as the single cam block was never ment to have a twin cam head, which is why the oil/water gallaries dont match. The rb25de non vct is of the same era blue print, so will bolt straight on. Though getting a non vct rb25de head is extremely hard.

Any chance you're heading down this road?

 

[C.A.R.]

Is there any more info on the M105 head conversion?

The thread on Hybrid seems to died...

[furrybarry]

Nothing I can find. The bloke who was planning it has piked out and decided to go with a complete m104 engine, and is on benz forums extracting information about how to hook a manual trans to it amongst other things.

 

I've been scruffing around Benz wreckers in Melbourne this week to try and find a cheap head to investigate the idea. There's a few about, but they must be used to ripping off wealthy grandmothers.
