Cruiseliner,

You have to use the balancer suited to the car its going in.

For example, I run my rb20det item, others may use their r33 item or rb26 item. :/

Use what ever came on your car so you can use your pwr steer and a/c.

An uncles VL cab did over 1mil on the stock bottom end, he did 3 sohc heads that I know of maybe more. :thumbsup:

He ran penrite gas oil, changed every 10k.

Suprisingly when the motor went it wasn't the bearings it was a gudgen pin.

Cabs cant be compared but yer.. its interesting to note

not sure on the balancer just yet but at first looks it looks like it should work.

as for the RB30's and how long they last, ive known of them doing up to 400,000k's and still been going strong.

mine has done 214,000 and the bores still look awesome. and im basically going to be doing exactly the same as you and throw the r33 rb25 head on the untouched rb30 bottom end and see how long it will last and the power i can get outa it. when it blows, if im happy with the power it makes and how long it lasted ill just get another $50 bottom end and start again.

whats the chances if i lean the engine out and lunch a piston that i do damage to the head/turbo/valves???

is it pretty rare to wreck the head if it leans out and blows a hole in a piston?

lots of dollars in my head and turbo i dont wanna lose to a silly tuning error :thumbsup:

Go too lean and you can burn exhaust valves.

I wouldn't worry too much, play on the safe side, be sure you have a good wideband thats reading correctly your other/better half driving (so you have some one to blame if things turn sour eheh) and your laughing. :thumbsup:

Will you really want to drop the 2.7ltr back in after running around with the 3ltr? :/

haha i was waiting for a comment like that, but 400hp is not enough and i think another 200hp+ on top of that will make the downsize a little easier to handle, plus the rpm limit of around 10k :/

a 30/26 will be goin in the stagea again soon enough :(

if i leave the 30 bottom end as it is when i buy it from a wrecked VL then is the adaptor still easy to install without removing the crank and stuff? whats all the grinding needed u mention? do i need to tap new

threads in the bottom of the 30 block for the sump adaptor or do u just use existing threaded holes?

so my interpretation of the mods needed for fitting 26 head on and sump adaptor are...

add 2nd tensioner to front of block

drill and tap block for 12mm rb26 head bolts

external oil pickup onto my existing 26 sump

the 2 bottom gearbox bolts dont lineup but i dont care as ive ran mine without then before

longer silicone joiners for cooler pipes

what happens with the radiator shroud??? or doesnt the height of the fan change?

4wd sump adaptor

modify top power steering bracket bolt hole

get longer timing belt

extend dump pipe for extra height

is that all or am i missing some things to do to make it all fit?

anyone care to answer my questions please??? :D

radiator shroud and fan should not be an issue , as the block is taller ABOVE the water pump so its location doesn't change.

modifying the engine mounts if you have clearance issues will cause these to foul though

as far as i have seen with these combo's its not required to change the tensioner locations.

Do remember this is a Stagea 4wd so the sump adaptor plate will throw 20mm or what ever it is on to the block and shift everything up slightly, so if anything the top of the shroud will be an issue, not the bottom like us rwd ppls where we lower the motor, essentially cruiseliner will be raising the motor, but as he runs the rb26 plenum this create any bonnet fouling issues.

thanx for that link to that site. ill check it now.

with the parts i already gotta complete turbo 25 sitting around i was gona use that, however there many peeps saying use an NA head coz of cams an easier fit is this true? what is the performance diff between NA an turb head?

wouldn't the plate just move the sump etc down, since the mounts are attached to the block above the sump plate/adapter area?

The 4wd sump adaptor is 6mm steel.

Moves the sump down, not the block up.

So, no effect on the water pump location relative to the radiator.

:D cheers :D

so whats this grinding i keep reading about on the bottom end to fit the sump adaptor???

and if the sump goes down 6mm lower is this going to then hit the x-member? or do i have to put spacers under the mounts to raise it so it clears ?

who is the sump adaptor available from sydneykid? im just organising everything and still deciding if ill go in this direction at the moment, and ill know in a few days if ill go ahead or not.

does the sump adaptor use the stock rb30 sump threaded holes or does it require new holes to be tapped into the 30 block ?

thanks again everyone :D

hey humz...its kewl man i didnt really give you anything to go on...just some common sense stuff. This is a site which maybe helpful to you also http://users.tpg.com.au/cobra30/twincam.htm .

I believe difference between na and turbo head is the vct, actually i think those details are in the start of the guide mate, just incase i spun you a porky pie there.

CruiseLiner - is it fitzpatrick speed works who has the lasercut adapter plates? Or is that for something else?

Hows the powerfc cubes r they gonna fix it??? So you can come for a cruse on friday :P Anyone else with an rb25/30 is welcome too :(

Hey Buddy, How did you go with the tune on Wednesday?

I won't be cruising, will be up at the Nannas on the other side of town for tea. :thanks:

Threw new tyres on the car and they have made a massive difference to traction, I'm able to get most of second down now and it actually feels damn fast. :(

Cool good to hear! :D , I took her down on wed to Tilbrook and i wasnt too impressed... firstly they didnt even know my car was booked in at the time they had booked it in and it was just shit customer service, so much for there $75 power run, which they all of a sudden changed to a dyno tune $650-700 on friday which i just lol'd at as they had to get someone else in to do the tune. Pissed me off because they didnt seem to know what they where talking about and i didnt want to leave my car in there hands and pay that much! So i went down to see shawn at BOOSTWORX told him u gave me a hand to tune her so far, he is a great bloke and seems to know what he is talking about. My car is now booked in next friday, which he told me would give me a chance to do some more k's on the motor hence why i chose to get my car tunned there, someone who knows there facts! So if you want to come down next friday if your free, we gonna spin her up on the dyno me and my mate captain thread (helped me build the motor) will be there to see what she can do, Shawn thinks that the standard cooler will cause a bit of a problem, what do you guys think i am only aiming for 220rwkw on 13psi which is what my wastegate is set to at the moment :( I do have a front mount i can put on before next week its just i was going to wait a while and do them all at once, then i had the following upgrades in mind, Q45 AFM, Q45 TB on front facing plenum, FMIC, 550cc injectors.

    • Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
    • Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/
    • Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)
    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
