the inside diameter of the stock runners is 39mm and average spacing of 95mm center to center, there not all the same apart from center to center, you cant see it from the drawing but there all measured within 1mm plus i am going to add some velocity stacks that will be able to attach to the exsisting flange.

Read complete thread and seen no mention of provision of clearance cut on bottom of bores to make sure top shoulder of rod does not hit on bottom of bore.

Not seen on image of bottom of block either so do you know if you have to do this?

It will become obvious on you first dummy fit and try to turn the crank slowly to see if you have the required clearance.

This is definitely done on the jap engines I have seen and it was mentioned in the Zoom 2.4 build up.

Good luck with it and hope it makes your target RWkW reliably! ;)

Hey guys,

Thanks for that, and yes was well aware of it but thanks for the heads up. When we did the dummy fit up, everything cleared fine 3 - 4mm clearence but we have ground some extra meat away just to be safe :(

Aighty, wellz we are having some problems finding the rings to suite the pistons, we didn't get them with rings with the pistons, and now that we have requested them they said can't do.. so we are stuck with pistons and no rings, this is the only thing stopping it all going to gether and being put in the car.

On another note a few people and pm'd asking for pics of the car its going into.

got any pics of the drivers side rear 1/4>>?? mine has some slight damage and was considering a kit like that, just wondering how is comes up to fuel filler. Also bit of noob with skyline features (silvia man) and was wondering. Are those 4 door taillights or did some 2 doors come with them? If they are 4 door lights.. how u fit them?? Just new rear bar n boot?

goodluck with ur engine biuld up.

cheers

Hey,

They are 2 door lights, as for the kit its a Final Konnexion genuine kit from Japan, through jetspeed. I will try get a pic of the drivers side rear for your tomorrow.

As for the rings,

Does anyone know the measurements of the rings etc? the pistons are made by ROSS

Cheers

You cut the intake runners how short? this thing is going to have even less down low than a stock RB20! We have spoken previously about plenums dude, I'll just remind you my mates' RB30DETT is making 460rwhp through a STANDARD RB25 plenum and throttle body.. good luck with the design and hopefully you don't lose too much torque or lean any cylinders out :(

Well put the car on the dyno last night to fiddle with the boost and AFR currently cars runnign a chipped mines ecu, and we wound the boost upto 1.15bar last night to test the timing and also to find a leak in the exhaust manifold, see the link below can you identify where the leak is lol

  • 4 weeks later...

Just a quick update.

Well Finally for ROSS pistons in the USA to organise my piston rings form Total Seal in Calafornia, They where posted monday, so hoping they will be here begining of next week.

Also i took the adivice of a few people and sold my Garrett 2876R setup, and today I received my new Garret GT30r, and also along with my new highmount manifold.

Just awaiting a few missing parts out of my oil & water line kit from GCG to arrive hopefully tomorrow and the turbo will be bolted upto the car

3076r.jpg

So far its coming along pretty smooth just a couple of hickups along the way but they where expected

Cheers

Cameron

What are the specs on the GT30R, as i thought the GT30R was meant to have the ported compressor cover?

Looks great though...also, if you are going to run that shiny nice manifold long and hard you should consider some shielding/wrap/ceramic coating etc. There is a lot of wiring and hoses around there that dont like heat. Also, its expensive but if you are running ahigh mount manifold and turbo then its worth the effort to get stainless steel braided teflon line and throw some of the red heat sheathing around it. I tried a few different hose types and installs and after a few heavy track days the oil return line showed signs of fatigue and drama. So went the whole hog 3rd tim eround and countless track days and thrashings later never missed abeat. Whislt plenty of other ppl at the track with high mounts have suffered similar fate to my earlier attempts.

But looking good, keen to see the results :)

Yea i will be heat wrapping the dump pipe, and most likely the manifold, also the oil return i was going to wrap in something to keep it safe.

last thing i want is a fire lol

The oil return line i have says its flame resistant lol but yea i will look into getting a steel braided teflon one :banana:

On a good note, rings cleared customs last night, after sitting there for 2 days but of thought they where some sort of hardcore substance

    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
    • That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.
    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.
