Thanks Santa (the neverending trials of the 400,000klm, 400kw, RB30, manual swapped Stagea)


Recommended Posts

Well it has been a while, but I picked up the car from Hills Motorsport yesterday.

It got dropped off as a standard engine bay with a pretty sick (not sik) motor. It came back like this:

stagea_2530.jpg

Basically it has an rb30 bottom end, skyline rb25 head, forged rods and pistons, new bearings, seals etc etc.

High mount ebay nugget t3/t4 turbo (go china!)

Front facing plenum

Pretty much everything else as before (powerfc, manual, sydneykid shocks and springs, d2 8spot front brakes).

So far its only being run in so it hasn't been pushed or tuned - but the torque down low is amazing and a real turn around from the normal (slightly disappointing) standard stagea feeling.

Turbo is making 7psi at 2,000 so I'm sure it will come on nice and early as I hoped, the run we did at 10psi had 160awkw which is a little more than the old setup made on 14psi - but the response even off boost is the real difference.

Very happy A+++ would buy again!

Congratulations! Good to hear. I got an RB30 bottom end (not installed as yet) because unforged it will stand more kw than the RB25 unforged and also have more torque all round . I would guess your engine will make around 280 - 300awkw now and have the potential for much more if you choose! [would you mind PM the drive in drive out price to me? I expect mine will be a little less because I am not getting forged rods and pistons and the front facing plenum will have to wait].

I bet you are a happy camper.

I drove around the yellow thing around today and all I think about is how another 500cc or so would make the car a whole lot nicer to drive in traffic.

How much did you spend on the new motor?

yeah it is beautiful to drive, especially pulling away from idle. no idea what it will actually end up doing, I was aiming for about 250kw but a focus on torque.

If I ever decide to get silly it has all of the required supporting stuff except injectors and an expensive turbo to go 300+.

Cost was about $10k but that did include some other stuff like a new alarm, clutch, intercooler etc etc.

I was going to keep the standard manifold but there may have been clearance issues to the bonnet, and the china front facing manifolds are dirt cheap these days.

$10k . . . i dont think i could ever part with that cash with out getting reamed by the miss's haha.

in one go though. here and there easy, but in one hit.

would have to spoil her for a month before to soften her up

I'd be pretty happy with that for $10k mate. you've got the goods plus a very clean, professional looking job.

if i may have a small nitpick though ( ;) ), it looks like your heatshield/airbox is covering/including your charged air intercooler pipe. it's something small, but i'd be keeping that on the outside of the airbox :P

edit:

tj, you've picked the wrong one! i've already pre-approved a $30k supra with mine ;) i'm still working on the 30k engine package though :):(

Pretty good drive in drive out price

Other expense that you have not listed is the sump adaptor to suit the awd sump and rb30 block. These are not cheap

Could you find which one they used and the cost of it?

yeah I am very happy with the price. $10k is a lot of money, but you have to look at how much time and parts there are in this build. I beleive it was very cheap for the work that was done. Good call on the cooler pipe, might see what I can do.

Nice, were there any issues getting it in and running, or was it all fairly straightforward?

nothing but trouble getting it running, but nothing to do with the job the shop did. For instance, once the whole thing had been assembled and put on the dyno the first time they discovered a crack in the block at a welsh plug at the rear of the head. I hadn't asked for it to be xrayed, they took a chance and lost. And then the second time it was put together the f**king alarm control module failed - but of course that is the last thing you think to check.

and of course the R34 GTT PFC is not a direct fit in my car which needed some stuffing around too.

once it was all together it has been fine though, and the run-in tune was quick and easy. Idle control has been a bit of a pain with the new plenum/throttle/cruise control/aac mvoed etc etc but its all good now.

Looks good!

what throttle body did you use on the plenum?

pretty sure it is the standard tb - I am not looking for more than 300kw from this setup and I'm sure the standard one will be enough for that.

Other expense that you have not listed is the sump adaptor to suit the awd sump and rb30 block. These are not cheap

Could you find which one they used and the cost of it?

yeah they used the pro-engines sump adaptor, about $800 including all fasteners from memory, fit first time without any mods required. also another complexity in a 4wd/rb30 is the oil pick up because the rb30 point is right where the driveshaft goes through the diff. the guys at hills modified it to plug the normal hole and drill into the block at the right place same as a 26 block - very precise work required to get that right. often people just run external oil feeds to the pump, that is probably both cheaper and easier.

once we have a house, the women don't care where my spare cash goes josh :blink: but for now it would be hell haha

lol don't you beleive it! once you have a house you have kids, then it's ALL over.

lucky you have the best wife ever eh Duncan?

:blink:

(and yes, I have a built in radar which automatically detects any thread you post comments about spending money on cars in)

Nice mate!

If you're going Chinese for the intake plenum (the greddy knockoffs) make sure you check for leaks before you drive it away. Look especially hard at the.. stalks? where it comes out of the engine, mine had a pinprick - 1 drop and thanks to the tuners these guys found and fixed it!

Leaks are easy to fix if spotted right away - a cooked engine is not what you want!

But that is bloody tidy, I've just had some work done myself, so I'll put up my build thread when I get a proper camera

lol don't you beleive it! once you have a house you have kids, then it's ALL over.

Its not over. You wait till your 66. :cheers:

Child slavery was invented by parents who wanted to still be able to afford such luxurys as motoracing.

nice work Duncan, the 30s do drive alot nicer than 25/26 capacity motors, especially in stop start traffic they just pull away from idle with ease.

You can buy the internal oil pickup with the pro engines sump adaptor kit and it bolts straight on without any hassle.

One thing to mention is when choosing this combo i feel a small turbo is not such a good idea (not aimed at you duncan). I run a 3076r on mine and it suffers from incrediblely shocking fuel economy, due to the car sitting on 0 on the vac/boost gauge at 100kmh on the freeway. Mines making over 20psi at 2900rpm which when on 100kmh on freeway its sitting on 2700rpm or so doesnt leave much until its wanting to get onto boost.

Im going to bolt my t04z on mine and see how it is, then probably get some 2860-5 lowmounts for longterm to keep it looking stock (i run 26 head)

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
