So yeah I got another manifold (stamped E30) for the Holley. It still needs an adapter but is a nicer lookin piece of kit then the one on the motor now.

What I need to know is when you guys change carby's/extractors what of the associated gear can be chucked in the leftovers pile and what needs to be kept connected?

I would like to remove as much shit as I can to tidy up the engine bay

Can this pipe coming out of the block to exhaust be deleted

The 20mm one with the smaller one off the side?

What else can go?

Also need a longer acclerator cable if anyone knows of anything useful?

Cheers Dan

This is the new manifold and adapter so far

Having looked at a bunch of Jap Nostalgia mags, it seems that everyone has a different idea about what to to with the crank breather; I've seen it blocked off with a welsh plug, connected with a hose to the rocker cover breather and finally allowed to vent to atmosphere via a filter. I'm with Ricky on this one, a little K and N filter tucked out of harm's way seems like the way to go.

As soon as I get my car back (this weekend) from the carby tuners I'll post some engine bay pics for you to compare with; as I have deleted as much as possible from my engine! No air con, power steer, EFI, ECU, AFM... it's pretty much bare bones.

Once again; it's great to see such an interesting project coming along.

Alrighty, thanks guys I'm slowly getting it sorted.

This is why I asked about the crank breather, the supercharger inlet is a tight fit on all sides.

So, If I cut the crank breather off a little closer to the block (removing the smaller vent hose all together) and plumb that to my crude little catch can will that remove the need for the PCV valve?

and if I go down this path, what then do I need to do with the fuel tank vent which is connected to the small crank case vent via this valve that also goes to the air filter housing.

Thanks again for your help, I'm all for leaving stuff as is (if it ain't broke), but most of this stuff will be redundant once the new manifold/Holley goes on.

so.....I tried fitting the new manifold but it's fouling on the old exhaust manifold heat exchanger, so I'm going to need to get a set of extractors I think.

Not having much luck finding a set for the Datto, just wondering if anything else will work, patrol/240/260/280z? anything else? I'm sure I've read that the z's won't work.

Cheers Dan

R30 extractors fit a treat. Most of my exhaust is R30 - you only run into problems around halfshafts/rear muffler.

I suspect that 240K extractors will fit, but maybe pointing in a bit of a strange angle under the car.

Also regarding the previous posts about what to do with the crank/rocker breathers, I was informed at the NDSOC show and shine if I want to do a sprint or hill climb in my car (and God knows I do) I will need to plumb both those guys into a canister or catch can of at least 1L capacity like your awesome Red Bull set up.

Ahh, thankyou good sir.

The patrol stuff looks to come down fairly sharply then sweep back, same basket as the z stuff i think.

As for my catch can, It came with my old KE70 turbo wagon and was replaced asap cause it was just to hectic for the car. It'll do for now untill I can make a new one.

Time to go shopping ;)

      PRP RB26 cast block + head prototype running

      By GTSBoy · Posted

      Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
