Just read the whole thread... Very nice engine build!

I love the attention to detail in building the engine, the only shame with the build is the short runner intake. Though it does look cool, you'll make much better power if you can add at least another 10 cm with a 90 deg vertical bend. A little bit of work in doing it, but it seems like you're the right man for the job!

My car started out life as a RB25DE and I very nearly made the decision to sub in a RB30 block (back in 2003) to up the HP keep it N/A. The RB is such a nice feeling (and sounding) engine in NA form I was keen to keep that alive, and also do something a little different. But alas, I went for the more cost effective option of dropping a RB25DET in.

Re: My comments on the short runners above

I'd buy 6 of something like this (or with thicker walls if you can find it):

http://www.ebay.com.au/itm/150mm-x-150MM-50MM-OD-Universal-Alloy-90-Bend-Pipe-/290370839983?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item439b7365af

They'd have an ID of 48mm, which is a pretty close match to the RB26 throttle body. Chop off the trumpets and weld them to the end of the bend, and you have some cool vertical velocity stacks! More power and a funkier look!

i am well aware of the shorter runners = more top end,

longer runners = more bottom end

unfortunatly there is the physical room to fit them, which isnt available

then there is the linkage holder, which there is a bar that was welded onto the trumpets to support that

www.jntperformance.com.au this is where i have bought the ramtubes from, they do have bends and longer ramtubes etc

Nothing wrong with putting a bend in the runners, 45-60deg will clear the clutch master and make their way towards the bonnet. Wouldn't be that hard at all to make....would be good to see some back to back testing if your keen. Pay for materials only ;)

Assembly time.

Kero washed everything, assembled, measured and calculated clearances, ring gaps etc, with flexi, feeler and dial gauges etc. Pulled apart re washed, then assembled using natural thiners and non-synthetic oils and assembly/ run in lubes, roughly dialing the cams in. All the usual stuff that should be done. I took my time and finally finished it over 2 weeks of making sure everything is 100% spot on and perfect

crank clearances all on mid size, piston to valve clearance 0.130" on intake 0.0180 on exhaust

Fitted the one off carbon fibre lower timing cover made. Had 3 dash 8 fittings welded onto the sump and fitted that, one for the drain kit, 2 for a catch can a bit further down the track. Also fitted the 90 amp alternator, engine mount brackets.

Pulled out the old rb30e, dropped the RB26/30DE in

Bought spitfire coil packs, silicon hose kit, fitted the ITB intake manifold, power steering

Sent it to Liverpool exhaust, they fitted equal length 3 into 2 into 1 extractors, hi flow cat, 2.5" mandrel bent exhaust with a resonator and a straight through muffler. Fitted the carbon fibre upper timing cover and coil pack cover when I got it back

Mick at Mick Motorsports wired up the Haltech Pro Sport 2000

I've since the tune, I had a little E10 in 98 pump problem, gave the head a quick reco but with very exact details everything like last build, while the head was off I started to make up my own ram tube manifold with gizmo thermal intake manifold gaskets

Mick at Mick Motorsports is sorting out the throttle body linkages and doing the final tune with cam timing and stuff

above is the most recent picture, not everything was put on as that was more of a dummy assemble

picked up an oil cooler and oil catch can to put on when it gets back

HI Are you still selling tihs engine set up.?

Send me a msg if you are.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
