The nismo Doesn't work on an RB30 block...with the turbo bolt-on return anyway. Def the go on a 26

Yeah I realise that but who has a 26 thesedays? Haha

I've been toying with making something like the NISMO one and the return plumbing into a Y/T piece after the turbos but it's all just thoughts and not a concern for practicality yet. Id like to know if for example the can was filled, and the return was into a turbo oil line what issues if any that would cause. Straight off the bat I was thinking about the line not being big enough for any extra oil and then the can wouldn't empty. Of course the best route is from the can straight to the sump but how many people will pull a sump out just to make one hole in it then put it back together esspecially in an awd car

Hence the dipstick return jobbies.

I reckon if you had that much oil in the can you'd have bigger problems? Considering what's in your system now stays in, I'm thinking it can't be that much.

Oh yeah agreed I'm thinking worst case here.

I'm just overthinking/complicating it all lol

I completed the Collinsgrove Hill climb on the weekend with the twin catch can setup.

The car went well, came second overall from 52...however I still have an oil problem. On my third run (read-lots of rpm)I managed to fill the primary can, and suck oil into the PCV...yes lots of smoke. I blocked the PCV for the next run and it was ok.

The setup is:

Passenger rocker cover joined to Drivers side rocker cover into the PCV and to the primary catch can, Primary catch can has a return to the dipstick (no check valve atm) the primary can outlet goes to the secondary can then from there into the rear turbo inlet. The covers are fitted with mines tripple flow baffles.

Potential Problems:

Baffle plates are not sealed anymore since going through the hot tank.

Sump is over filled (filled to the full mark on the RB30 Dipstick)

Less than 1.5mm restrictor required in the head

Too much oil pressure(7.7kg idle cold, 4kg warm, 7.5kg above 3000rpm warm)

Too much oil flow

Too thin oil (Nulon 10w40)

Not enough head drainage

Not enough baffle plate drainage (once oil gets into stage 3 of the plate)

What I will try (in order)

Le Mans 20w60 Oil (reduce oil flow), Check baffle plates

Install check Valve in return line

Install rear head drain. (most likely a small electric oil pump This pump Or this or thisgoing to the Dipstick from both Half moons)<---- you heard it from me first. The pump will be Hobbs switch, G-sensor, or TPS activated

Reduce Oil pressure

Install smaller restrictor( this is a last option for me...really not keen on reducing the flow to a level that may see issues when driven quietly on the street.)

i also run 20-60 lemans & it is a very good oil but super expensive.

i pay $60 for 2ltr & need 8ltr for each oil change

The question on my mind is it suitable for E85. I have to run the PCV- you should see how much condensation there is on cold start from E85 in the breathers.

thats good to know that lemans 20-60 is compatible with e85 as i am making the switch very soon

I looking at getting my injectors from here Rb26 injectors

Most likely 1350 or 1450cc. My 1000cc at 4bar base do not cut it.

im running the bosch indy blues 1600cc - my tuner was very happy with them, why dont u get those? cheap as well when compared to jap hardware

u do need to get a suitable fuel rail though to run these 14mm injectors (factory is 11mm) & custom spacers for the fuel rail as the injectors are taller as well

On e85?

From my experience around 1400 would be good. I use ID2000's, not cheap, but they're excellent

where did you by them and how does the car idle...what rpm?

Mercury Motorsport

Idles fine, just like stock except for the lumpy cams. Idle is set to 950rpm.

There's vids on YouTube if you wantto look then up but they wont help with this at all

The biggest shock was the low speed/throttle drivability. Before it was shit on light throttle or carpark speeds and I just put that down to the 1000's being so large. The ID's are just like stockers. Sure they're not cheap, but nothing good is!

The tuner, who does a LOT of tuning in Syd was over the moon with them and couldn't believe how good they are compared to the Indy blues which of course until the ID2000's came around were the big injector of choice for e85 cars

thats surprising stevo - are they that much nicer to tune with than indy blues?

mine idles beautifully with big cams :D

i think at the end of the day, u need to go with hardware which your tuner is happy with or can work with - for example, there is no point running a vipec if your tuner prefers working with a pfc

$1800 for injectors is a little insane..

Some of the Honda guys have been having trouble with these injectors on idle.

I can't remember the exact wording as it was a while ago but the points he was making was;

-Better to tune

-Better to drive

-something about response time

-Well worth the expense

He tunes with any gear that people bring in, so for someone as widely respected to say that, and after driving it back to back on the 1000's, that's good enough for me :(

    • I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies. 
    • It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest. 
    • Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks! 
    • It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers
    • Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...
